I. Executive Summary

A. Purpose and Coverage of the Proposed Rule

    The proposed rule, if finalized, would amend our regulations at 
parts 170 and 570 (21 CFR parts 170 and 570) to require the submission 
of GRAS notices for the use of a human or animal food substance that is 
purported to be GRAS under the conditions of its intended use under 
section 201(s) of the FD&C Act (21 U.S.C. 321(s)). Food 
substances include both ingredients and substances added indirectly, 
such as from food packaging. The proposed rule would require any person 
introducing a substance into interstate commerce under the GRAS 
provision of section 201(s) of the FD&C Act to notify FDA of the basis 
for their conclusion that the substance is GRAS under the conditions of 
its intended use unless an exception to the requirement to submit a 
GRAS notice applies. This change would provide greater transparency 
about substances that are added to food (including substances already 
in the food supply and those being introduced into interstate commerce 
for use in food for the first time), so that FDA can more efficiently 
determine if the use of a substance constitutes a food additive use 
that is subject to FDA review and approval under the FD&C Act. This 
change is expected to provide FDA with information to help identify the 
use of potentially unsafe substances in food, thereby enabling FDA to 
take action as appropriate and regulate the safety of food substances 
more effectively.

B. Summary of the Major Provisions of the Proposed Rule

    The proposed rule, if finalized, would:
     Convert the voluntary GRAS notification program to a 
mandatory GRAS notification program and explain that if the 
notification requirement is not met for a substance's conditions of 
intended use, FDA would consider such noncompliance as a factor in its 
prioritization of food substances for post-market review;
     Establish certain exceptions to the requirement to submit 
a GRAS notice, including a time-limited option to make a streamlined 
submission to FDA for certain intended uses of substances already in 
interstate commerce instead of initially submitting a GRAS notice; and
     Revise our procedural regulations for a threshold of 
regulation (TOR) exemption for human food to reflect updated scientific 
guidance and to include uses of substances in food and as a food 
contact substance (FCS).

C. Legal Authority

    We are issuing this proposed rule consistent with our authority in 
sections 201, 402, 409, and 701 of the FD&C Act (21 U.S.C. 321, 342, 
348, 371).

D. Costs and Benefits

    This proposed rule would revise the procedures by which a person 
introducing a human or animal food substance into interstate commerce 
notifies FDA of a conclusion that the use of such substance is GRAS. 
Specifically, the proposed rule would require the submission of GRAS 
notices to FDA for certain uses of food substances. A substance that is 
GRAS under the conditions of its intended use is not subject to FDA 
premarket review and approval as a food additive for that particular 
use (see sections 201(s) and 409 of the FD&C Act). Under our current 
regulations, a person who concludes that the use of a substance is GRAS 
under the conditions of its intended use may, but is not required to, 
notify FDA of this conclusion. The submission of a GRAS notice is 
therefore currently voluntary. If the proposed rule is finalized, GRAS 
notices will be required for certain uses of substances in human and 
animal food.
    The primary benefits of the proposed rule, if finalized, would come 
from increased information being made available to FDA and the public 
regarding substances used in human and animal foods. This information 
would enable us to more effectively determine if the use of a substance 
constitutes a food additive use that is subject to premarket review and 
approval under the FD&C Act. This information is also expected to 
provide FDA with information to help identify the use of potentially 
unsafe substances in food, thereby enabling FDA to take action as 
appropriate and regulate the safety of food substances more 
effectively. A mandatory GRAS notification program would allow FDA to 
ensure that GRAS conclusions have a scientific basis and that 
appropriate documentation supporting those conclusions exists. The 
proposed rule, if finalized, is in part intended to help

[[Page 51836]]

strengthen public confidence in FDA's ability to oversee the safety of 
the U.S. food supply. One-time costs of the proposed rule to persons 
who introduce a substance into interstate commerce under the GRAS 
provision of section 201(s) of the FD&C Act include reading the rule 
and revising standard operating procedures regarding GRAS notices. 
Other one-time per manufacturer costs of the proposed rule are 
preparing and submitting streamlined submissions related to uses of 
substances introduced into interstate commerce under the GRAS provision 
of section 201(s) of the FD&C Act before the effective date of a final 
rule, for firms that choose to submit this information during the 
window of availability for this time-limited option for such 
submissions. Costs associated with these activities may include 
translation costs for manufacturers in non-English speaking countries. 
Recurring costs to affected manufacturers would include preparing and 
submitting GRAS notices for new uses of substances introduced into 
interstate commerce under the GRAS provision of section 201(s) of the 
FD&C Act after the effective date of a final rule that would otherwise 
have been the subject of an independent conclusion of GRAS status 
(i.e., a GRAS conclusion has been reached without submitting a GRAS 
notice) (see sections III and VII of this document for further 
discussion of independent conclusion of GRAS status and effective and 
compliance dates, respectively).
    Costs to FDA would include one-time costs of reviewing streamlined 
submissions related to uses of substances introduced into interstate 
commerce under the GRAS provision of section 201(s) of the FD&C Act 
before the effective date of a final rule during the time-limited 
period for such submissions, and annual costs of evaluating ongoing 
submissions of GRAS notices regarding uses of substances that would 
otherwise have been the subject of an independent conclusion of GRAS 
status.
    Other effects of the proposed rule may include transfers of market 
share and revenue between manufacturers of products with similar 
ingredients. For example, the submission of a GRAS notice may lead to a 
determination by FDA that there is an insufficient basis for concluding 
that a substance that happens to be used in only certain of the 
products was GRAS. We acknowledge the potential for such transfers if 
the rule is finalized. We do not estimate the magnitude of such effects 
because we cannot identify which substances may be the subject of an 
insufficient basis letter, which products they are in, or the market 
share of such products.
    We estimate that the present value of the costs of the proposed 
rule would be approximately $89.6 million, with a lower bound of $34.9 
million and an upper bound of $210.0 million, discounted at 3 percent 
at 10 years in 2024 dollars. At a 7 percent discount rate, the present 
value of costs would be approximately $82.3 million, with a lower bound 
of $31.5 million and an upper bound of $195.9 million. We estimate that 
the annualized costs of the proposed rule would be approximately $10.5 
million, with a lower bound of $4.1 million and an upper bound of $24.6 
million, discounted at 3 percent over 10 years. At a 7 percent discount 
rate, annualized costs would be approximately $11.7 million, with a 
lower bound of $4.5 million and an upper bound of $27.9 million.

III. Background

    On March 10, 2025, the Secretary of Health and Human Services, 
Robert F. Kennedy Jr., directed FDA to explore rulemaking to eliminate 
the pathway for firms to introduce purported GRAS uses of substances 
into the market without notifying FDA of the basis for their GRAS 
conclusions (Ref. 1). Secretary Kennedy's call for a reformed GRAS 
notification process aligns with the Administration's Make America 
Healthy Again initiative by providing increased transparency about the 
substances being added to the nation's food supply (Ref. 2). A 
mandatory GRAS notification program would require any person 
introducing a substance into interstate commerce under the GRAS 
provision of section 201(s) of the FD&C Act to notify FDA of the basis 
for their conclusion that the substance is GRAS under the conditions of 
its intended use. A mandatory program would enable FDA to more 
effectively ensure the safety of the U.S. food supply--one that has 
grown far more complex in recent years--by providing us with 
information needed to help identify the use of potentially unsafe 
substances in food or additives that require FDA's review and approval 
to be lawfully marketed, so we can take action as appropriate. A 
mandatory GRAS notification program would therefore address growing 
concerns about the increasingly complex U.S. food supply. For example, 
firms are introducing substances into food without publicly disclosing 
the underlying safety information about the use of such ingredients and 
FDA sometimes becomes aware of the need to take action regarding unsafe 
substances in food only after adverse public health events occur. 
Further, a mandatory program that includes the continued public 
disclosure of information about GRAS uses of substances would 
substantially increase the public's access to information concerning 
the substances being added to human and animal food.
    In 1958, Congress enacted the Food Additives Amendment to the FD&C 
Act (the 1958 amendment) (Pub. L. 85-929, 72 Stat. 1784), which 
expanded FDA's broad authority under the FD&C Act to ensure the safety 
of the U.S. food supply. Among other things, the 1958 amendment created 
a new framework for FDA's oversight of substances being added to food. 
The 1958 amendment defined the term ``food additive'' and established a 
premarket review and approval framework for these food substances 
(sections 201(s) and 409 of the FD&C Act). Notably, in defining what 
constitutes a food additive subject to premarket review and approval, 
the 1958 amendment excluded substances that are GRAS under the 
conditions of their intended use (section 201(s) of the FD&C Act). 
Congress therefore exempted substances that are GRAS under the 
conditions of their intended use from the premarket review and approval 
requirements for food additives under the FD&C Act. However, as 
discussed elsewhere in this document, Congress struck a balance: 
although it exempted substances that are GRAS under the conditions of 
their intended use from premarket review and approval, Congress granted 
FDA the authority to review food substances on the market, including 
new and existing substances introduced into food that are purported to 
be GRAS under the conditions of their intended use, to assess whether 
these substances meet the definition of a food additive that requires 
premarket authorization (sections 409(a) and (d) of the FD&C Act).
    In the over 60 years since the enactment of the 1958 amendment, FDA 
has regulated GRAS uses of substances in food through various 
mechanisms, including by: listing certain substances as GRAS under the 
conditions of their intended use in our regulations; conducting a 
comprehensive study of purported GRAS uses of substances to determine 
whether certain uses of substances required FDA's review and approval 
as food additive uses; and establishing a GRAS affirmation process, 
through which interested parties could petition us to affirm the GRAS 
status of a particular use of a substance.
    Our current GRAS notification program was first proposed in 1997, 
and under this program, parties can voluntarily notify us of a 
conclusion that a substance is GRAS under the conditions of its 
intended use. Through a GRAS notice, parties can share with us the 
underlying data and other scientific information used to support their 
conclusion that the use of a substance is GRAS under the conditions of 
its intended use. A GRAS conclusion constitutes an assertion on the 
part of the notifier (i.e., the person responsible for the GRAS notice; 
see Sec.  170.203 (21 CFR 170.203) and Sec.  570.203 (21 CFR 570.203)) 
that the intended use of a substance is not a food additive use that is 
subject to the premarket review and approval requirements of section 
409 of the FD&C Act. Importantly, a person's conclusion that a 
substance is GRAS under the conditions of its intended use (or similar 
claims by a person that they have independently ``certified'' the use 
of a substance as GRAS) does not necessarily mean that such a use is 
GRAS or that the use is not an unapproved food additive use. For 
example, FDA may determine, based on an assessment of evidence, that 
the use of a substance is not GRAS or that it is otherwise an 
unapproved food additive.
    As part of our voluntary GRAS notification program, once we file a 
GRAS notice, we conduct an evaluation to determine whether the data and 
information presented, and other information available to FDA, provide 
a sufficient basis for a conclusion that the substance is GRAS under 
the conditions of its intended use. In general, FDA will respond to a 
GRAS notice in one of three ways: (1) by indicating that we do not 
question the basis for the GRAS conclusion contained in the notice 
(``no questions'' letter); (2) by indicating that we have concluded 
that the notice does not provide a sufficient basis for a GRAS 
conclusion (e.g., because the notice does not include appropriate data 
and information or because key data and information are not publicly 
available); or (3) by stating that we have granted a request by the 
notifier for us to cease our evaluation of the GRAS notice. There is no 
requirement that a notifier must wait to receive a response from FDA 
regarding their GRAS conclusion before introducing the substance into 
interstate commerce. We provide information about GRAS notices and our 
responses on our website (Refs. 3 and 4).
    While the current GRAS notification program has been informative 
and beneficial to our administration of the FD&C Act, our nearly 30 
years of experience with the program, and particularly our experience 
administering the program since it was finalized in 2016, has 
highlighted several challenges.
    The voluntary nature of the GRAS notification program has meant 
that information gaps persist for both FDA and the public about 
substances being added to food, an issue covered extensively in a 2010 
U.S. Government Accountability Office (GAO) report (see section 
III.B.1.c of this document for further discussion) (Ref. 5). Our lack 
of complete information about what substances are being added to food 
has, at times, prevented early engagement with industry about new uses 
of substances in food and frustrated our ability to carry out our 
public health and safety responsibilities under the FD&C Act (see 
section III.B of this document for further discussion). At the same 
time, recent changes in our country's food supply, such as evolving 
consumer demand for different types of

[[Page 51838]]

products and ongoing innovation in food manufacturing and ingredient 
development, have resulted in a more diverse food supply. It was 
estimated that, as of January 2011, more than 10,000 additives were 
being used in food, including an estimated 1,000 human food substances 
for which firms had claimed independent conclusions of GRAS status 
(i.e., they had reached a GRAS conclusion without submitting a GRAS 
notice) (Refs. 6 and 7).
    In light of the issues we have identified with the voluntary GRAS 
notification program, and the challenges we face due to ongoing food 
innovation and evolving consumer demands, we find ourselves in a 
situation much like the years before the 1958 amendment's enactment. At 
that time, numerous substances with unknown safety profiles were being 
added to or used in connection with food without sufficient FDA 
oversight. Today, an unknown number of substances are being introduced 
into the market under the GRAS provision of section 201(s) of the FD&C 
Act. The proposed rule would address our current circumstances by 
requiring the submission of GRAS notices. Mandatory submission of GRAS 
notices would increase knowledge and improve the transparency about 
substances in the U.S. food supply that are purported to be GRAS under 
the conditions of their intended use. It would give FDA, state 
regulators, consumers, industry, and consumer advocacy groups more 
information about substances being used in human and animal food. Once 
filed, information about all purported GRAS uses of substances is 
expected to enable FDA to more efficiently determine whether the use of 
a substance meets the definition of a food additive use under the FD&C 
Act, and therefore whether the use of the substance requires FDA's 
review and approval to be lawfully marketed. Further, mandatory 
submission of GRAS notices would help FDA ensure that GRAS conclusions 
have a scientific basis and are appropriately documented and 
maintained. It would also provide an earlier opportunity for us to 
engage with industry if questions arise regarding a conclusion that a 
substance is GRAS under the conditions of its intended use. Mandatory 
submission of GRAS notices would enable FDA to administer and enforce 
the FD&C Act more effectively and efficiently.

A. Statutory and Regulatory History

1. The Food Additives Amendment of 1958
    In 1950, to address emerging health concerns about the use of new 
chemicals in food, the U.S. House of Representatives established a 
committee chaired by Representative James Delaney of New York (the 
Delaney Committee) to investigate the substances being added to or used 
in connection with the nation's changing food supply. The Delaney 
Committee issued a report in June 1952 summarizing its findings (Ref. 
8). The report found, among other things, that food substances were 
being used ``without adequate and sufficient testing of their possible 
long-range injurious effects'' (id. at 27). The report further 
concluded that the public was ``entitled to greater protection with 
respect to the foods it must necessarily consume[,]'' and that ``such 
protection [was] not afforded by existing legislation, under which the 
Government may take no action until after the food has been placed upon 
the market and injury may have occurred'' (id. at 27). The Delaney 
Committee therefore recommended that the FD&C Act be amended to require 
premarket safety reviews for ``chemicals employed in or on foods'' (id. 
at 27).
    In 1958, based in part on the Delaney Committee's report, as 
referenced in the corresponding House Report (Ref. 9), Congress enacted 
the Food Additives Amendment to the FD&C Act to strengthen government 
oversight of substances being added to or used in connection with food. 
``Food'' includes articles used for food or drink for humans or other 
animals and articles used for components of such food (see section 
201(f) of the FD&C Act); therefore, the 1958 amendment covered 
additives in both human and animal foods. Echoing the Delaney 
Committee's call for premarket oversight of food substances, Congress's 
stated purpose in passing the 1958 amendment was ``[t]o protect the 
public health by amending the [FD&C Act] to prohibit the use in food of 
additives which have not been adequately tested to establish their 
safety'' (Pub. L. 85-929, 72 Stat. 1784).
    Specifically, the 1958 amendment requires that, before certain 
substances may be added to food, FDA must authorize their use through a 
premarket review and approval process (sections 409(b) through (e) of 
the FD&C Act). Among other things, the 1958 amendment:
     defines what constitutes a ``food additive'' subject to 
premarket review and approval (now codified at section 201(s) of the 
FD&C Act);
     creates a detailed premarket authorization process for 
food additives that can result in a food additive regulation 
establishing the safety of a food additive for a particular use 
(sections 409(a) through (e) of the FD&C Act);
     enables any person to submit a food additive petition to 
propose the issuance of a food additive regulation (section 409(b) of 
the FD&C Act);
     empowers the Secretary of the U.S. Department of Health 
and Human Services (the Secretary) to at any time, on their own 
initiative, propose the issuance of a food additive regulation (section 
409(d) of the FD&C Act); and
     deems adulterated any food that is, or bears or contains, 
a ``food additive that is unsafe within the meaning of section 409 [of 
the FD&C Act]'' (now section 402(a)(2)(C)(i) of the FD&C Act).
    With some exceptions, section 409(a) of the FD&C Act provides that 
food additives are deemed ``unsafe'' for purposes of the adulteration 
provision of section 402(a)(2)(C)(i) of the FD&C Act unless their use 
conforms with a food additive regulation issued pursuant to the 
premarket review and approval process of section 409 of the FD&C Act. 
Congress later added to this premarket authorization framework by 
establishing a mandatory food contact notification program for human 
foods (see section 409(h) of the FD&C Act) and certain requirements 
specific to food additives intended for use in animal food (see section 
409(k) of the FD&C Act).
2. Statutory Approach to Substances Generally Recognized as Safe (GRAS)
    In enacting the 1958 amendment, Congress recognized that many 
substances added to food would not need to go through formal premarket 
review and approval to assure their safety, either because their safety 
had been established by a long history of use in food or by virtue of 
the nature of the substance, its customary or projected conditions of 
use, and the information generally available to scientists about the 
substance. Therefore, Congress adopted a two-step definition of ``food 
additive'' (see section 201(s) of the FD&C Act). The first step broadly 
includes any substance, the intended use of which results or may 
reasonably be expected to result, directly or indirectly, in its 
becoming a component or otherwise affecting the characteristics of 
food. This includes substances added to food directly (i.e., 
ingredients) and indirectly (i.e., substances used in contact with 
food). As such, substances that migrate or may reasonably be expected 
to migrate into food from their intended use in contact with food 
(e.g.,

[[Page 51839]]

from conveyor belts, containers for shipping, packaging for food) would 
be regulated as food additives unless such use is GRAS or otherwise 
excepted from the definition of a food additive. Further information 
about food contact substances is available on our website (see Ref. 
10). The second step excludes from the definition of a ``food 
additive'' substances that are generally recognized, among experts 
qualified by scientific training and experience to evaluate their 
safety, as having been adequately shown through scientific procedures 
(or, in the case of substances used in food before January 1, 1958, 
through either scientific procedures or through experience based on 
common use in food) to be safe under the conditions of their intended 
use. Under section 201(s) of the FD&C Act, the conditions of intended 
use of a substance, rather than the substance itself, are eligible for 
GRAS status. Similarly, food additives are deemed unsafe when their 
conditions of use do not conform with a food additive regulation (see 
section 409(a) of the FD&C Act).
    The 1958 amendment created two distinct processes for the proposal 
and creation of food additive regulations. First, under section 409(b) 
of the FD&C Act, any person may propose the issuance of a food additive 
regulation by filing a petition with the Secretary. Under section 
409(c) of the FD&C Act, in response to a food additive petition, the 
Secretary, and by delegation, FDA, will, by order, either: (1) deny the 
petition; or (2) establish a food additive regulation prescribing the 
conditions under which the food additive may be safely used. Second, 
under section 409(d) of the FD&C Act, Congress specifically authorized 
the Secretary, and by delegation, FDA, to at any time, upon the 
Secretary's own initiative, propose the issuance of a food additive 
regulation prescribing the conditions under which a particular food 
additive may be safely used. After 30 days, the Secretary, and by 
delegation, FDA, may issue an order establishing a food additive 
regulation based upon the proposal (section 409(d) of the FD&C Act).
    Section 409(d) of the FD&C Act thus authorizes us to propose food 
additive regulations of our own accord. As discussed further in section 
IV of this document, by granting FDA authority to propose food additive 
regulations upon our own initiative and at any time, Congress intended 
for FDA to play a critical role in determining whether a food substance 
being introduced into interstate commerce, including one already being 
added to food, meets the definition of a food additive and requires a 
food additive regulation to be lawfully marketed.
3. FDA's Regulatory Approach to the GRAS Provision of Section 201(s) of 
the FD&C Act
    We have periodically revised our regulations to adapt our approach 
to the GRAS provision of section 201(s) of the FD&C Act to the nation's 
changing food supply and to address issues we identified after years of 
experience under prior regulatory schemes. The revisions were intended 
to help us better understand what substances are being added to or used 
in connection with food under the GRAS provision of section 201(s) of 
the FD&C Act. The goal of these regulations was to give us, and the 
public, safety information about these substances and to enable us to 
take appropriate actions to assure the safe use of these substances in 
food. Shortly after Congress amended the FD&C Act in 1958, we clarified 
the regulatory status of many substances that were added to food before 
1958, and we ultimately amended our regulations to include a list of 
food substances that, when used for the purposes indicated and in 
accordance with good manufacturing practices, are GRAS. The list, 
historically referred to as ``the GRAS list,'' can be found at part 182 
(21 CFR part 182) for human food and part 582 (21 CFR part 582) for 
animal food.
    When creating the GRAS list, we acknowledged that it would be 
impracticable for us to list all substances that are GRAS for their 
intended use in our regulations (Sec.  121.101(a) (later renumbered as 
Sec.  182.1(a) (21 CFR 182.1(a)) and Sec.  582.1(a) (21 CFR 582.1(a))). 
Consequently, we did not include many substances considered GRAS under 
the conditions of their intended use by the food industry in the GRAS 
list. Despite the fact that a substance that is GRAS under the 
conditions of its intended use is not subject to FDA premarket review 
and approval as a food additive for that particular use (see sections 
201(s) and 409 of the FD&C Act), firms who concluded on their own 
initiative that a use of a substance qualified for GRAS status 
frequently sought our opinion on whether their conclusion was 
justified. Many firms requested an ``opinion letter,'' in which FDA 
would render an informal opinion on the GRAS status of the conditions 
of use of a substance. Although convenient and expedient, these 
informal opinion letters were often available only to the requestor and 
were not binding on us even at the time they were issued.
    FDA updated the GRAS list over time. For example, in the Federal 
Register of October 21, 1969 (34 FR 17063), we deleted from the GRAS 
list various cyclamate salts, a family of nonnutritive sweeteners that 
had been added to food under the GRAS provision of section 201(s) of 
the FD&C Act, because they were implicated in the formation of bladder 
tumors in rats (Ref. 11). Later, in response to concerns raised by the 
new information on cyclamates, then-President Nixon directed FDA to 
reexamine the safety of all substances included on the GRAS list (Ref. 
12). We subsequently announced that we were conducting a comprehensive 
study of these substances (35 FR 18623, December 8, 1970). The purpose 
of the study was to evaluate the available safety information for 
substances on the GRAS list. For substances determined safe under their 
conditions of use, we would then repromulgate each substance in a new 
(i.e., affirmed) GRAS list, a food additive regulation, or an interim 
food additive regulation pending completion of additional studies. In 
conjunction with this comprehensive study, we revoked informal GRAS 
opinion letters issued before April 9, 1970, in part because many 
letters no longer resided in FDA's files; thus, in the absence of 
information concerning the names and uses of the substances in the 
letters, the safety of all such substances and uses could not be 
reexamined (35 FR 5810, April 9, 1970) (see Sec.  170.6 (21 CFR 170.6) 
and Sec.  570.6 (21 CFR 570.6)).
    In the notice announcing the comprehensive review of substances 
included on the original GRAS list, we proposed criteria that could be 
used to establish whether the use of these substances should be 
included on a new GRAS list, become the subject of a food additive 
regulation, or be listed in an interim food additive regulation pending 
completion of additional studies (35 FR 18623). We incorporated these 
criteria into our regulations as Sec.  121.3 (21 CFR 121.3) (36 FR 
12093, June 25, 1971) (renumbered as Sec.  170.30 (21 CFR 170.30) for 
human food and Sec.  570.30 (21 CFR 570.30) for animal food; see 41 FR 
38618, September 10, 1976, and 42 FR 14302, March 15, 1977). We later 
announced that we were conducting a study of certain GRAS substances 
(36 FR 20546, October 23, 1971) and subsequently instituted a 
rulemaking to establish procedures that we could use, on our own 
initiative, to affirm the GRAS status of substances that were the 
subject of that review and were found to satisfy the criteria 
established in Sec.  121.3 (proposed rule, 37

[[Page 51840]]

FR 6207, March 25, 1972; final rule, 37 FR 25705, December 2, 1972). We 
recodified these procedures at Sec.  170.35(a) and (b) (21 CFR 
170.35(a) and (b)) for human food (42 FR 14302) and Sec.  570.35(a) and 
(b) (21 CFR 570.35(a) and (b)) for animal food (41 FR 38618). Because 
the GRAS review did not cover all GRAS substances (e.g., substances 
that were marketed based on a firm's conclusion of GRAS status), the 
1972 rulemaking included a mechanism (the GRAS affirmation petition 
process) whereby an individual could petition us to review the GRAS 
status of substances not being considered as part of our GRAS review. 
If we agreed that the substance was GRAS under the conditions of its 
intended use, we could affirm the use of the substance as GRAS in our 
regulations. Our affirmations of GRAS status are currently codified in 
parts 184 and 186 (21 CFR parts 184 and 186) for human food and part 
584 (21 CFR part 584) for animal food.
    Petitions submitted as part of the GRAS affirmation process 
informed us, the domestic and international food industry, and the 
public of conclusions of GRAS status. However, this framework proved to 
be resource-intensive (e.g., FDA issued a rule proposing to affirm a 
substance as GRAS under the conditions of its intended use and affirmed 
the GRAS status in a final rule). Therefore, in the Federal Register of 
April 17, 1997 (62 FR 18938), we proposed to: (1) clarify the criteria 
for eligibility for classification as GRAS; and (2) replace the 
voluntary GRAS affirmation petition process with a voluntary GRAS 
notification procedure. In the Federal Register of August 17, 2016 (81 
FR 54960) (the 2016 GRAS final rule), we finalized the voluntary GRAS 
notification regulation in Subpart E of part 170 (21 CFR part 170) for 
human food and Subpart E of part 570 (21 CFR part 570) for animal food. 
The regulations provide that any person may notify FDA of a view that a 
substance is not subject to the premarket review and approval 
requirements of section 409 of the FD&C Act based on that person's 
conclusion that the substance is GRAS under the conditions of its 
intended use (see Sec.  170.205 (21 CFR 170.205) and Sec.  570.205 (21 
CFR 570.205)). We explained that we would evaluate whether the data, 
information, and narrative in a GRAS notice support that conclusion (81 
FR 54960 at 55035; see also Sec.  170.265(b) (21 CFR 170.265(b)) and 
Sec.  570.265(b) (21 CFR 570.265(b))).

B. The Need To Mandate GRAS Notifications

    The voluntary GRAS notification program has improved our efficient 
administration of the FD&C Act by providing us with more data and 
information about uses of substances in food. GRAS notices have 
informed us about new food substances entering the market, including 
some substances into which we might not otherwise have insight. GRAS 
notices have therefore provided us with information that improved our 
understanding of the U.S. food supply and enhanced our ability to 
protect public health by helping to identify the use of potentially 
unsafe substances in food or additives that require FDA review and 
approval to be lawfully marketed, so we can take action as appropriate.
    As part of an interim pilot program created with the 1997 proposed 
rule, parties began notifying us about their conclusions of GRAS status 
(62 FR 18938 at 18954). FDA's former Center for Food Safety and Applied 
Nutrition (now called the Human Foods Program (HFP)) filed its first 
GRAS notice in 1998 under the interim pilot program. As of March 25, 
2025, HFP has filed over 1,200 GRAS notices (Ref. 3). FDA's Center for 
Veterinary Medicine (CVM) established its interim pilot program more 
recently (75 FR 31800, June 4, 2010) and filed its first GRAS notice in 
December 2010. As of March 28, 2025, CVM has filed 75 GRAS notices 
(Ref. 4).
    In addition to providing us with more information about uses of 
substances in food, the voluntary GRAS notification program has 
improved our administration of the FD&C Act in other ways. For example, 
the voluntary GRAS notification program created new opportunities for 
us to engage with industry to learn more about the U.S. markets for 
human and animal food. Under the voluntary GRAS notification program, 
FDA routinely engages with industry through pre-submission meetings and 
related consultations. We also work with industry to improve GRAS 
notice submissions and recommend the necessary data and other 
information to facilitate a successful evaluation of a GRAS notice. 
These opportunities to engage with stakeholders provide us with more 
information about human and animal food substances, and they enable us 
to better achieve our ultimate goal of helping to identify the use of 
potentially unsafe substances in food or additives that require FDA 
review and approval to be lawfully marketed, so we can take action as 
appropriate.
    Despite the benefits of our GRAS notification program, we have 
identified challenges with our current voluntary approach to GRAS 
notifications. These challenges, which we describe in the sections that 
follow, have created obstacles to fulfilling our statutory 
responsibility to determine if the use of a substance constitutes a 
food additive use that is subject to the premarket review and approval 
requirements of section 409 of the FD&C Act. We are, therefore, 
proposing a mandatory approach to GRAS notifications to better serve 
these purposes.
1. Issues Identified Over the Course of the Voluntary GRAS Notification 
Program
    After nearly 30 years of receiving and evaluating GRAS notices, and 
after filing more than 1,200 GRAS notices, FDA has identified several 
issues with the current voluntary approach to GRAS notifications. We 
describe some issues we have identified with a voluntary approach to 
GRAS notifications in greater detail in the following sections.
    a. Issue #1: Inadequate analyses to support independent conclusions 
of GRAS status can result in unapproved food additive uses. Due to the 
voluntary nature of the GRAS notification program, we have periodically 
learned about the continued use of substances in food that we have 
publicly indicated constitute unapproved food additive uses. It may be 
unclear whether such substances are being used based on a new 
independent conclusion of GRAS status and, if so, what data and 
information a firm may be relying on to substantiate that conclusion.
    The continued use of stevia leaves and crude extracts of stevia 
leaves provide one such example. We first issued an import alert in 
1991 for crude extracts of stevia leaves and foods containing stevia 
leaves or stevia extracts to prevent the importation of unsafe stevia 
products into the United States. We have updated the import alert to 
add firms subject to the import alert and to account for uses of 
purified extracts for which FDA does not have questions following the 
review of a GRAS notice. The most recent update issued in 2025 
continues to recommend detention without physical examination of stevia 
leaves, crude extracts of stevia leaves, or foods containing these 
substances (Ref. 13). The import alert states that, when used in 
conventional foods, stevia leaf, or its crude extract, is not an 
approved food additive and is not considered GRAS due to inadequate 
toxicological information necessary to demonstrate safety. In contrast, 
the safety of high purity (greater than or equal to 95 percent pure) 
steviol glycosides, the sweetening molecules found in stevia leaves, is 
well-established, and FDA has evaluated and issued ``no questions'' 
letters in response to multiple GRAS notices

[[Page 51841]]

regarding highly purified forms of steviol glycosides. Notwithstanding 
these developments regarding high purity steviol glycosides, FDA's 
position on stevia leaves and their crude extracts has remained clear 
and consistent since the 1991 import alert--their use is not considered 
GRAS and constitutes an unapproved food additive use. Despite our 
unambiguous position regarding stevia leaves and stevia leaf crude 
extracts since 1991, we continue to find products containing these 
substances. In 2022, for instance, FDA issued a warning letter about 
the use of an unapproved food additive--stevia leaf--in several green 
tea products (Ref. 14).
    Our experience under the voluntary GRAS notification program has 
further demonstrated that some firms may not be conducting sufficient 
analyses of whether their use of a substance in food is GRAS. FDA 
advises firms that preserving the applicable data and information that 
forms the basis of an independent conclusion of GRAS status represents 
prudent practice for those who assert that the statutory premarket 
review and approval requirements for food additives do not apply to the 
use of a substance in food (81 FR 54960 at 55028; see also 62 FR 18938 
at 18947). We encourage firms to maintain the data and information that 
support the independent conclusion of GRAS status in the form of a GRAS 
notice (81 FR 54960 at 55027; see also Ref. 14). We also recommend that 
a firm make public the basis for its independent conclusion of GRAS 
status, as that aligns with FDA's practice to make GRAS notices 
publicly available (Ref. 15) and our goal of increasing transparency.
    Notwithstanding these recommendations, we have learned that some 
firms may not conduct an evaluation that is sufficient to establish 
that a substance is GRAS under the conditions of its intended use. 
Firms also may not have the data and information that adequately 
support the basis for an independent conclusion of GRAS status. These 
observations are troubling given that firms are responsible for the 
safe manufacture of food being introduced into interstate commerce, 
including assuring the safety of substances used in making a food 
product.
    Several examples illustrate the real-life consequences of these 
trends. In 2009, we received a letter from 18 Attorneys General and one 
city attorney expressing concerns about caffeinated alcoholic beverages 
(Ref. 16). FDA advised manufacturers that we were considering whether 
caffeine could lawfully be added to alcoholic beverages (Ref. 17). We 
informed these firms that there are no food additive regulations 
authorizing the use of added caffeine in alcoholic beverages, that such 
use was not prior sanctioned, and that we had not determined the use to 
be GRAS (id.). We gave them 30 days to submit their rationale, 
supporting data, and information for their conclusion that the use of 
caffeine in alcoholic beverages was GRAS or prior sanctioned. One firm 
said that it would prepare and submit a GRAS notice to us (Ref. 18), 
but it took more than 7 months for us to receive their GRAS notice. We 
identified several questions for the submitted notice, and in the end, 
we granted the firm's request to cease to evaluate the GRAS notice 
(Ref. 19).
    During our evaluation of the GRAS notice, we issued four warning 
letters to firms marketing caffeinated alcoholic beverage products, 
including the firm that submitted the GRAS notice (Ref. 20). We stated 
in the letters that, based on the publicly available literature, a 
number of qualified experts have concerns about the safety of 
caffeinated alcoholic beverages. We further stated that FDA is not 
aware of data or other information to establish the safety of caffeine 
as used in these products. We informed firms marketing these 
caffeinated alcoholic beverages that caffeine, as used in the firms' 
products, is an unsafe food additive, and that the products are thus 
adulterated under section 402(a)(2)(C) of the FD&C Act. The firms 
subsequently ceased distribution of these products. This experience 
yielded a valuable insight into our GRAS notification program--had the 
firms marketing caffeinated alcoholic beverages been required to submit 
GRAS notices, we could have reviewed the information provided and 
informed firms much earlier that this use of caffeine rendered the 
substance a food additive requiring premarket review and approval.
    We have drawn similar insight from our more recent experience 
involving human food products containing Delta-8 tetrahydrocannabinol 
(THC). In 2024, we sent warning letters to several firms for selling 
human food products that were represented as containing Delta-8 THC 
(Ref. 21). We stated that no food additive regulation authorizes the 
use of Delta-8 THC and that the use of the substance was not prior 
sanctioned. The warning letters went on to explain that available data 
raise serious concerns about the potential harm from Delta 8-THC, 
including adverse effects on the central nervous and cardiopulmonary 
systems and that some studies in animals suggested gestational exposure 
can interfere with neurodevelopment. The warning letters also cited 
adverse event reports related to ingestion by children and adults of 
edible products containing Delta-8 THC. The letters concluded that, 
based on FDA's review, the use of Delta-8 THC in conventional foods did 
not meet the criteria for GRAS status in FDA's regulations and that 
these products contained an unsafe food additive rendering them 
adulterated under section 402(a)(2)(C)(i) of the FD&C Act.
    When we are not aware of an independent conclusion of GRAS status, 
we do not know what data and other information a firm uses to support 
their GRAS conclusion. Thus, there may be independent GRAS conclusions 
for currently marketed uses of substances for which we would typically 
have questions about their GRAS status. Without data and information, 
we cannot follow up on these questions as we would if we received a 
deficient voluntary GRAS notice. Moreover, in the case of independent 
conclusions of GRAS status, we may not become aware of a firm's poorly 
supported GRAS conclusion until after a product becomes available to 
consumers and, in some cases, only after an adverse event occurs.
    For example, in 2022, a firm that used tara flour as an ingredient 
in a human food product initiated a voluntary recall of that product 
after it was associated with roughly 400 adverse event reports that 
detailed, among other things, gastrointestinal distress, 
hepatotoxicity, and hospitalization (Ref. 22). The firm conducted its 
own root cause analysis and identified tara flour as a possible 
contributor to the illnesses. We requested, but the firm did not share 
with FDA any records or other indication that demonstrated that they 
had reached a GRAS conclusion regarding the use of tara flour in human 
food. FDA evaluated the regulatory status of tara flour, which had not 
been the subject of any prior GRAS notice or a GRAS pre-submission 
meeting. We determined that there are not enough data on the use of 
tara flour in food, or a history of its safe use in food before 1958, 
to consider it GRAS, and there is also no food additive regulation 
authorizing the use of tara flour in food (id.). We posted our 
assessment of tara flour to FDA's ``Post-market Determinations that the 
Use of a Substance is Not GRAS'' website (Ref. 23). If we had received 
information from the firm through a GRAS notice earlier, we could have 
advised them of the need for information and studies to establish 
safety.
    In addition to posting ``not GRAS'' memos to our website, we also 
issue import alerts or warning letters in

[[Page 51842]]

situations where we have first evaluated the regulatory status of an 
ingredient, such as following inspection activities. For example, in 
2023 FDA placed ashwagandha, an evergreen shrub whose extracts were 
identified in some human food products, on Import Alert 99-45 after FDA 
inspectors raised questions about its regulatory status and deemed it 
to be an unsafe food additive (Ref. 24). As a result, FDA may detain, 
without physical examination, shipments of certain identified food 
products containing ashwagandha from firms on the Red List of Import 
Alert 99-45. Ashwagandha has not been the subject of a voluntary GRAS 
notice.
    These examples demonstrate that, under the current voluntary GRAS 
notification program, firms sometimes lack a sufficient basis for GRAS 
conclusions, resulting in the use of unapproved food additives in our 
food supply. In some cases, we become aware of the need to take action 
regarding unsafe additives in food only after learning of adverse 
public health events. Mandating the submission of GRAS notifications 
would enable us to better address concerns regarding the potential use 
of unapproved food additives in foods by providing us with information 
about independent conclusions of GRAS status. It would also further 
improve our administration of the FD&C Act by providing more 
opportunities for us to engage with industry to understand the basis 
for these GRAS conclusions.
    b. Issue #2: Substances introduced into the marketplace after we 
cease to evaluate a GRAS notice at a notifier's request. The voluntary 
GRAS notification program provides that notifiers may request that FDA 
cease to evaluate a GRAS notice (see Sec.  170.260(b) (21 CFR 
170.260(b)) and Sec.  570.260(b) (21 CFR 570.260(b))). We noted in the 
2016 GRAS final rule that a cease to evaluate letter signals that a 
GRAS notice does not provide an adequate basis for a conclusion that 
the notified substance is GRAS under the conditions of its intended 
use, even though we do not issue an insufficient basis letter regarding 
the notified substance (81 FR 54960 at 55010).
    In current practice, notifiers request that we cease to evaluate a 
GRAS notice for a variety of reasons. For example, if we have questions 
about a GRAS notice that cannot be addressed by a timely amendment, a 
notifier may ask us to cease evaluating their GRAS notice so that they 
can later submit a new GRAS notice that addresses our questions. During 
our evaluation of a GRAS notice, we also may raise issues regarding the 
data and information used to support the GRAS conclusion. If our 
questions about the underlying support for a GRAS conclusion cannot be 
easily resolved, notifiers may request that we cease reviewing the 
notice while they develop or compile additional data to address the 
issues raised. For GRAS notices pertaining to substances used in animal 
food, notifiers have sometimes sent us cease to evaluate requests after 
we have raised questions about proposed contaminant limits in their 
GRAS notices.
    In some cases, a notifier who received a cease to evaluate letter 
submits a new GRAS notice for the use of the notified substance after 
addressing our questions, and we respond to the new GRAS notice with a 
no questions letter. Alternately, after receiving a cease to evaluate 
letter from FDA, some notifiers may decide not to submit a new GRAS 
notice and instead to make an independent conclusion of GRAS status and 
market the substance or food containing the substance. If a notifier 
does not submit a new GRAS notice to FDA after receiving a cease to 
evaluate letter, we have no information about whether the previously 
notified substance later entered the market based on an independent 
conclusion of GRAS status. We also do not have insight into whether any 
questions we raised about the notified substance were adequately 
addressed. In such cases, this could cause confusion about whether the 
use of a substance meets the definition of a food additive use under 
the FD&C Act, and therefore whether the use of the substance requires 
FDA review and approval to be lawfully marketed. Our existing voluntary 
GRAS notification program creates the opportunity for a notifier to 
introduce a substance about which we had safety questions into the 
market without providing transparency to FDA and the public regarding 
the basis of their GRAS conclusion.
    c. Issue #3: Insufficient information hinders FDA's efficient 
administration of the FD&C Act. Due to the voluntary nature of our 
current GRAS notification program, a firm can market a substance that 
it has concluded is GRAS under the conditions of its intended use 
without submitting a notice to FDA. This prevents us and the public 
from having knowledge about, and insight into, these purported GRAS 
uses of substances. Our lack of a complete understanding of what 
substances are being used in the food supply impedes our ability to 
efficiently carry out our role under the FD&C Act to prohibit the use 
of unsafe additives in food and protect public health.
    In GAO's 2010 report entitled ``Food Safety: FDA Should Strengthen 
Its Oversight of Food Ingredients Determined to be Generally Recognized 
as Safe (GRAS),'' GAO noted that FDA generally has no information about 
GRAS determinations that are not submitted to the voluntary 
notification program (Ref. 5 at page 12). (We use the terms ``GRAS 
conclusion'' or ``conclusion of GRAS status'' instead of ``GRAS 
determination''; see 81 FR 54960 at 54969.) The GAO report included one 
example of a firm indicating that it ``makes about 5 GRAS 
determinations each year without notifying FDA'' (Ref. 5 at page 12). 
These GRAS determinations usually pertained to ``new uses of substances 
that have been deemed GRAS for other uses'' (id. at page 12). The GAO 
report further stated that FDA is less informed about the U.S. food 
supply and consumers' cumulative dietary exposure to GRAS substances 
because we do not oversee all GRAS determinations (id. at page 13). GAO 
recommended that we develop a strategy to require any firm that 
conducts a GRAS determination to provide FDA with basic information 
about the identity and use of the substance (id. at page 34).
    As discussed in our response to the GAO Report, we share the 
transparency goal underlying GAO's recommendation to require the 
submission of basic information about GRAS uses of substances (Ref. 5). 
In the 2016 GRAS final rule, we said that a voluntary approach to GRAS 
notifications would mitigate many issues GAO raised in its report. For 
instance, we noted that a voluntary GRAS notification program would 
enable us to evaluate more, and higher priority, substances (81 FR 
54960 at 54961). We also discussed the increasing use of the voluntary 
GRAS notification program throughout the interim pilot program (id. at 
54980). However, after nearly a decade of additional experience 
administering the voluntary GRAS notification program, and in light of 
the ongoing changes to the nation's food supply discussed in greater 
detail below, the risks of not requiring GRAS notifications have become 
more evident.
    As of January 2011, some sources estimate that there were 1,000 
substances in use in human food for which firms had claimed independent 
conclusions of GRAS status (Refs. 6 and 7). However, given that the 
current GRAS notification program is voluntary, we have little, if any, 
information on independent conclusions of GRAS status, including the 
identity of the substance and its intended use(s).
    Regarding food contact substances, specifically, we operate two 
programs (the infant formula notification program and the food contact 
substance

[[Page 51843]]

formulation review program) where food packaging producers submit their 
packaging product formulations to us to verify compliance with FDA 
regulations. These programs provide FDA with limited opportunities to 
obtain information on independent conclusions of GRAS status. Through 
these programs, FDA has reviewed submissions where the inclusion of 
certain food contact product components is based on claims that the 
component is GRAS under the conditions of its intended use. While these 
programs provide us with some insight into independent GRAS conclusions 
made about those components, we lack a complete understanding of the 
number of substances currently on the market based on an independent 
conclusion of GRAS status.
    In addition, our lack of a complete understanding of the substances 
added to food prevents us from efficiently sharing knowledge and 
providing transparency to others, such as state regulators, food 
manufacturers, and consumers, about substances in interstate commerce 
that are purported to be GRAS under the conditions of their intended 
use. For example, both HFP and CVM receive questions from state 
regulators, the regulated industry, and consumers about the regulatory 
status of such substances in human and animal food. Responding to these 
inquiries can often be challenging, as the lack of information we have 
on many substances impedes FDA's ability to effectively provide 
oversight in partnership with state regulators.
    We are also aware that confidence in the federal government's 
ability to ensure the safety of the U.S. food supply, generally, has 
declined. The percentage of U.S. adults who say they have a ``great 
deal'' or ``fair amount'' of confidence in the government to keep the 
food supply safe fell from 68 percent in 2019 to 57 percent in 2024 
(Ref. 25). Consumers indicate they would have more confidence in the 
safety of the U.S. food supply if they better understood how the 
federal government and industry work together to ensure food safety or 
if the federal government's regulations on food safety were stricter 
(Ref. 26). This general lack of consumer confidence speaks to an 
overarching need for the federal government to work to strengthen 
public confidence in the safety of the U.S. food supply--this proposed 
rule would be one example of a way to strengthen public confidence 
through increased transparency about the substances being added to the 
nation's food supply.
    Unless a voluntary GRAS notice has been filed, we may not have 
insight into whether a given substance is GRAS under the conditions of 
its intended use without expending significant FDA resources to 
identify whether publicly available data supports the safe use of the 
substance. Aside from our GRAS notice inventory, which does not cover 
independent conclusions of GRAS status, no publicly available list 
exists where we or interested parties can verify the use in interstate 
commerce of all substances purported to be GRAS under the conditions of 
their intended use. Our inability to proactively share knowledge and 
provide transparency regarding all such substances may undermine public 
confidence regarding FDA's ability to protect public health. It also 
impedes our ability to effectively and efficiently regulate the U.S. 
food supply.
2. The Changing Food Supply in the United States
    The country's continually evolving food supply also presents new 
challenges to our efficient administration of the FD&C Act. As 
referenced elsewhere in this document, some sources estimate that, as 
of January 2011, there were more than 10,000 additives in use in food, 
including an estimated 1,000 human food substances for which firms had 
claimed independent conclusions of GRAS status (Refs. 6 and 7). 
Although we cannot verify the accuracy of these estimates, these 
figures, and the statistics from our voluntary GRAS notification 
programs for both human and animal food, describe a food supply that is 
markedly different from the one FDA regulated when it first began to 
implement the 1958 amendment.
    The Delaney Committee, for instance, stated in its 1952 report that 
FDA representatives testified during a 1950 hearing that there were in 
total ``704 chemicals employed in food use'' at that time (Ref. 8), of 
which ``428 [were] definitely known to be safe'' (id.). In contrast, 
HFP and CVM combined have filed over 670 GRAS notices since January 
2016 and more than 1,200 GRAS notices in total since 1998 when FDA 
began filing GRAS notices under the interim pilot program. (We note 
that multiple GRAS notices may pertain to the same substance (i.e., 
they describe different conditions of intended use).) Information from 
GRAS notices we have filed also highlights the increasingly complex and 
globalized nature of our food supply. Of the more than 1,200 filed GRAS 
notices, 617 were submitted by foreign firms, and 503 of these were 
submitted by foreign firms located in countries where English is not 
the primary language.
    An additional challenge is that, for certain nutrients, dietary 
exposure estimates are approaching the tolerable upper intake level 
(UL) established by the Institute of Medicine (IOM) (now the National 
Academies of Sciences, Engineering, and Medicine). A nutrient's UL is 
the highest level of daily intake that is likely to pose no risk of 
adverse health effects (Ref. 27). A UL may differ for individuals at 
different life stages (e.g., children ages 9 through 13 years, adults 
over 70 years) and is determined using a risk assessment approach 
developed specifically for nutrients (id.). Notably, whether a 
substance in food is contributing to dietary exposure approaching a 
nutrient's UL is information that is critical to our assessment of both 
whether a given use of a substance renders it a food additive use, and 
whether the use of a food additive is safe.
    A case study of calcium demonstrates the importance of such 
information. Calcium is an essential nutrient necessary for numerous 
physiological processes, including formation/metabolism of bone, and 
intracellular signaling related to muscular function, vascular 
contraction/dilation, nerve transmission, and hormonal secretion (Ref. 
28). Maintenance of calcium balance is essential for the body's normal 
function (Id.). The IOM established ULs between 2,000 and 3,000 
milligrams per day for different life stage groups among the population 
aged 4 years and older (Ref. 29). However, excessive supplemental 
calcium intake can lead to certain health complications, such as an 
increased risk for kidney stones (Refs. 29 and 30).
    To assess the safety of calcium, which we would do when we are 
evaluating a submission for a calcium salt, such as a food additive 
petition, color additive petition, or GRAS notice, we consider the IOM 
ULs relative to the cumulative dietary exposure estimates. Since 2017, 
our evaluations regarding uses of calcium salts for human foods have 
shown that cumulative dietary exposure estimates to calcium have been 
increasing (see 82 FR 51554, November 7, 2017; and 87 FR 58445, 
September 27, 2022). In 2024, we noted that the dietary exposure 
estimate for calcium at the 90th percentile was approaching the IOM's 
upper limit for calcium of 2000 mg for population groups 51-70 and 71 
years and older (Ref. 31). We also noted that the National Cancer 
Institute (NCI) developed a validated model to estimate the usual 
dietary intakes of episodically consumed foods and dietary

[[Page 51844]]

supplements (NCI usual dietary intakes method) (id.).
    In a recent final order listing calcium phosphate (a calcium salt) 
as a color additive in ready-to-eat chicken products, white candy 
melts, doughnut sugar, and sugar for coated candies, we stated our 
literature search identified no new publications relevant to the safe 
use of calcium in food, and therefore, the current state of the science 
supports the continued use of the IOM UL for calcium as a dietary 
reference value to support public health (90 FR 20097, May 12, 2025). 
During our review, and in consultation with us, the petitioner amended 
the intended uses of calcium phosphate to remove the use in icing and 
reduce the use level in sugar for coated candies to reduce overall 
dietary exposure to calcium (id. at 20098). Using 2015-2020 National 
Health and Nutrition Examination Survey food consumption data combined 
with the NCI usual dietary intakes method, we estimated the cumulative 
dietary exposure to calcium from the background dietary sources, 
including dietary supplements and drugs, and the petitioned uses to be 
1,195 mg/p/d at the mean and 1,789 mg/p/d at the 90th percentile for 
the U.S. population ages 2 years and older (id.). If the petitioner had 
not amended the intended uses of calcium phosphate, then overall 
dietary exposure to calcium would have exceeded the UL for certain life 
stage groups.
    We anticipate continuing to see nutrients approaching, and 
potentially exceeding, the UL, which, in certain cases, would present 
questions about the safe use of such ingredients and raise health 
concerns that we would want to address. Ongoing consumption of 
substances that are purported to be GRAS under the conditions of their 
intended use, as well as consumption of new substances that are 
purported to be GRAS under the conditions of their intended use, may be 
contributing to these trends. Without a mandatory GRAS notification 
requirement, FDA will not always be aware of what uses of substances 
are contributing to nutrient consumption approaching the UL, nor will 
FDA always be provided with sufficient information to engage with firms 
to address questions and concerns about such issues.
    Another facet of the changes we are seeing to the nation's food 
supply is the increase in individually packaged single-serving foods 
along with the growing awareness both by food manufacturers and 
consumers about the environmental impact of disposable food packaging 
(Ref. 32). This has resulted in initiatives to substitute certain food 
packaging materials, in particular plastics made from petroleum 
sources, with alternative packaging materials thought to have lower 
environmental impacts (id.). Many of these alternative packaging 
materials are bio-based (i.e., derived from raw materials such as 
plants), which may be perceived as less toxic than petroleum-based 
plastics (Ref. 33). In some cases, users of these alternative materials 
may consider them to be GRAS under the conditions of their intended use 
and may choose not to go through FDA's review programs prior to 
bringing their products to market. As stated elsewhere in this 
document, due to the voluntary nature of our current GRAS notification 
program, a firm can market a substance that it has concluded is GRAS 
under the conditions of its intended use without submitting a notice to 
FDA. The Food and Drug Administration Modernization Act amended section 
409 of the FD&C Act to establish the food contact notification program 
for food contact substances that are food additives, as an alternative 
to food additive petitions. Food contact notifications (FCNs) or food 
additive petitions are not required for food contact substances that 
are GRAS. Therefore, companies use the GRAS provision of the statute to 
conclude that a food contact substance is GRAS and that a food contact 
notification or a food additive petition is not required. This prevents 
us and the public from having knowledge about, and insight into, these 
purported GRAS uses of substances. This proposed rule would provide 
flexibility to companies to submit an FCN instead of a GRAS notice for 
food contact substances if they prefer to use the FCN process. Note, in 
contrast to GRAS notices, food contact notifications and the intended 
use are specific to the listed manufacturer or supplier for the 
effective FCN.
    Our lack of a complete understanding of what substances are being 
used in the food supply impedes or delays our ability to efficiently 
carry out our role under the FD&C Act to prohibit the use of unsafe 
additives in food and protect public health.
    For example, we recently evaluated, on our own initiative, 
dinnerware (i.e., bowls, plates, cups, cutlery) manufactured from the 
sheath of leaves from the Areca catechu (A. catechu) plant (Ref. 34) 
after inquiries from industry as to whether this use would require 
premarket authorization. Our research shows that naturally occurring 
toxins in these products migrate into food at levels that may pose a 
potential safety concern to consumers (Ref. 35). Therefore, the use of 
the sheath of A. catechu palm leaves in food contact articles such as 
dinnerware does not meet the statutory criteria for GRAS, and no 
authorizations exist for its use in food (Ref. 34). We issued a letter 
informing retailers, distributors, and importers of dinnerware 
manufactured from the sheath of leaves from the A. catechu plant that 
such dinnerware may not be lawfully offered for sale in the U.S. (Ref. 
36), and we added palm leaf dinnerware to Import Alert 23-15 (Ref. 37).
3. How a Mandatory GRAS Notification Program Would Address These Issues 
and Challenges
    A mandatory GRAS notification program would provide FDA with 
information, in the form of a GRAS notice, on the uses of substances 
that would otherwise be marketed under an independent conclusion of 
GRAS status. The proposed amendments to convert our current voluntary 
GRAS notification program to a mandatory program would increase the 
level of knowledge and transparency about substances in the U.S. food 
supply that are purported to be GRAS under the conditions of their 
intended use. This would provide FDA, state regulators, consumers, and 
industry with more information about substances being added to human 
and animal food and enable FDA to establish a more comprehensive 
catalog of what substances are being added to food. These proposed 
changes would help ensure that GRAS conclusions have a scientific basis 
and that sufficient documentation supporting those conclusions is 
developed and shared with FDA. This information would be accessible to 
the public within a few weeks of filing through FDA's GRAS Notice 
Inventory, which is available on our website and where we currently 
maintain this information (Refs. 3 and 4), thereby increasing 
transparency about purported GRAS uses of substances (see section V.K 
of this document for further discussion). These proposed changes would 
also enhance our ability to efficiently carry out our role under the 
FD&C Act to prohibit the use of unsafe additives in food and protect 
public health. Therefore, the proposed rule, if finalized, is in part 
intended to help strengthen public confidence in FDA's ability to 
oversee the safety of the U.S. food supply.
    A mandatory GRAS notification program would also help ensure that 
human food safety, as well as target animal safety in the case of 
animal food GRAS notices, is fully assessed as part of a notifier's 
GRAS conclusion. This information would help us to more efficiently 
determine whether the use of

[[Page 51845]]

a substance meets the definition of a food additive use under the FD&C 
Act, and therefore whether the use of the substance requires FDA review 
and approval to be lawfully marketed. A mandatory GRAS notification 
program would also respond to GAO's recommendation to develop a 
strategy to require any firm that conducts a GRAS determination to 
provide FDA with basic information about the identity and use of the 
substance.
    In addition, a mandatory GRAS notification program would provide us 
with insight into any current uses of substances that were the subject 
of a cease to evaluate letter. Only some notified substances that were 
the subject of a cease to evaluate letter were later the subject of a 
new GRAS notice for the same intended use. While our existing voluntary 
GRAS notification program does not prohibit a notifier from making an 
independent conclusion of GRAS status and entering the market with a 
use of a substance that was the subject of a cease to evaluate letter, 
this, in practice, leads to the same lack of knowledge that we have 
when it comes to other independent conclusions of GRAS status. Unless 
we receive a voluntary GRAS notice or there is a public health concern 
prompting us to evaluate the use of an ingredient, we do not always 
know how such substances are being used. Making GRAS notice submissions 
mandatory would eliminate much of the confusion over whether a 
substance is GRAS under the conditions of its intended use, because 
these GRAS conclusions and their underlying data would be publicly 
available along with our response letters.
    Information about levels of added nutrients, such as calcium, would 
help FDA evaluate the uses of nutrients across the food supply to 
accurately evaluate dietary exposure. Mandatory GRAS notices would 
provide more transparency about the ingredients, such as calcium salts, 
being used in the food supply, including how they are being used and at 
what levels. Such information would give us greater insight into 
whether these ingredients pose safety concerns under certain conditions 
of use, which might render them food additives subject to premarket 
review and approval for those uses.
    Ultimately, the proposed rule would help us better carry out our 
statutory responsibility to prohibit the use of unsafe additives in 
food. The proposed rule, if finalized, would create a framework whereby 
firms would still be able to render their own GRAS conclusions, but 
they would be required to submit these GRAS conclusions to FDA in 
accordance with subpart E of parts 170 and 570. Mandatory GRAS notices 
would provide us with safety information about substances that are 
purportedly GRAS under the conditions of their intended use, helping us 
to carry out our statutorily-defined role under sections 409(a) and (d) 
of the FD&C Act of determining whether uses of substances introduced 
into interstate commerce constitute food additive uses that are subject 
to premarket review and approval. The proposed rule would, therefore, 
aid in our effective and efficient administration of the FD&C Act.

IV. Legal Authority

    We are proposing to amend parts 170 and 570 to require submission 
of GRAS notices for certain substances added to or used in connection 
with human or animal food under our authority in sections 201, 402, 
409, and 701 of the FD&C Act. Specifically, the proposed rule would 
require any person introducing a substance into interstate commerce 
under the GRAS provision of section 201(s) of the FD&C Act, for which 
the conditions of intended use of such substance are not covered by one 
of several exceptions listed in the rule, to notify FDA of the basis 
for a conclusion that the conditions of intended use of the substance 
are GRAS.

A. Statutory Framework

    As discussed in section III.A.1 of this document, in 1958 Congress 
amended the FD&C Act to address growing concerns about the increasing 
number of chemicals being added to the nation's food supply. As 
amended, the FD&C Act requires that all food additives (as defined by 
section 201(s) of the FD&C Act) be approved by FDA before they are 
marketed or used in food (sections 402(a)(2)(C)(i) and 409 of the FD&C 
Act). Sections 409(a) through (h), and also (k) for animal food, of the 
FD&C Act authorize FDA to approve a food additive by issuing an order 
establishing a regulation regarding the food additive's safety for a 
particular use. In particular, sections 409(b) and (d) of the FD&C Act 
set out in detail the two types of processes that may result in orders 
establishing food additive regulations: (1) under section 409(b) of the 
FD&C Act, any person may file with the Secretary a petition proposing 
the issuance of a food additive regulation; and (2) under section 
409(d) of the FD&C Act, the Secretary (or his delegate) may propose the 
issuance of a food additive regulation at any time, upon his own 
initiative. In addition, section 409(h) of the FD&C Act provides for a 
process through which the intended use of a food additive that is an 
FCS becomes authorized through a notification submitted by the 
manufacturer or supplier. With some exceptions, food additives are 
deemed unsafe food additives under section 409(a) of the FD&C Act 
unless their use conforms with a food additive regulation. Foods that 
are, or bear or contain, unsafe food additives are deemed adulterated 
under section 402(a)(2)(C)(i) of the FD&C Act, rendering them potential 
targets for enforcement actions under the FD&C Act (e.g., sections 302 
and 304 of the FD&C Act).
    Section 201(s) of the FD&C Act excludes from the definition of a 
food additive a substance generally recognized, among experts qualified 
by scientific training and experience to evaluate its safety, as having 
been adequately shown through scientific procedures (or, in the case of 
a substance used in food before January 1, 1958, through either 
scientific procedures or experience based on common use in food) to be 
safe under the conditions of its intended use. Thus, substances that 
are GRAS under the conditions of their intended use are not subject to 
the food additive premarket review and approval requirements of section 
409 of the FD&C Act.

B. Legal Basis for the Proposal

    The proposed rule would provide FDA with information about 
substances being introduced into interstate commerce under the GRAS 
provision of section 201(s) of the FD&C Act. Specifically, the proposed 
rule would require the submission of information about the intended use 
of such substances and the data and information supporting the 
conclusion that the substance is GRAS under the conditions of its 
intended use. Because the conditions of intended use of these 
substances, together with available safety data, may render them food 
additives subject to premarket review and approval, requiring the 
submission of information about these substances and their intended 
uses would help FDA efficiently carry out its responsibilities under 
sections 409(a) and (d) of the FD&C Act to propose and establish food 
additive regulations.
    When read together, sections 409(a) and (d) of the FD&C Act task 
the Secretary, and by delegation, FDA, with identifying food substances 
that have not been the subject of a food additive petition or an FCN 
and with initiating review of the safety of such substances for 
particular uses. See Se. Minerals, Inc. v. Harris, 622 F.2d 758, 767 
(5th

[[Page 51846]]

Cir. 1980) (citing, inter alia, section 409(d) of the FD&C Act and 
Weinberger v. Hynson, Westcott & Dunning, Inc., 412 U.S. 609, 624 
(1973)) (``The FDA has the authority to determine whether a particular 
product requires an approved food additive regulation in order to be 
marketed in interstate commerce.''). Thus, sections 409(a) and (d) of 
the FD&C Act authorize FDA to review substances on the market, 
including new and existing substances introduced into food that are 
purportedly GRAS under the conditions of their intended use, to assess 
whether these uses constitute food additive uses that require a food 
additive regulation to be lawfully marketed. The proposed rule, which 
would require persons introducing certain substances into interstate 
commerce under the GRAS provision of section 201(s) of the FD&C Act to 
notify FDA of the basis for their conclusion that the use of a 
substance is GRAS, would help FDA to efficiently carry out these 
statutory responsibilities.
    Specifically, requiring the submission of GRAS notifications would 
better enable us to monitor what substances are being added to or used 
in connection with food by alerting us to substances on the market that 
we might not otherwise know exist. This includes uses of substances in 
food that were the subject of independent conclusions of GRAS status, 
and thus uses of substances that FDA otherwise may learn about only 
after public health concerns are raised. Further, requiring the 
submission of GRAS notices would provide us with safety information 
about substances that are purportedly GRAS under the conditions of 
their intended use, which would help us to determine whether such uses 
of substances actually constitute food additive uses that are subject 
to the premarket review and approval requirements of the FD&C Act. See, 
e.g., Se. Minerals, Inc., 622 F.2d at 767 (``FDA, as the administrative 
agency created by Congress to administer the [FD&C Act], cannot 
intelligently and rationally perform its regulatory duties unless it 
determines what products are `food additives' . . . and what products, 
because of their GRAS status, are exempt from regulation.''). This 
information would also support FDA's compliance and enforcement 
activities related to the use of unapproved food additives, such as the 
issuance of warning letters and seizure of adulterated foods. A 
mandatory GRAS notification program would therefore help us to fulfill 
the underlying purpose of sections 409(a) and (d) and related 
provisions of the FD&C Act by providing us with information that better 
enables us ``[t]o prohibit the use in food of additives which have not 
been adequately tested to establish their safety.'' See Public Law 85-
929, 72 Stat. 1784 (1958).
    The proposed rule, if finalized, would thus facilitate FDA's 
efficient administration and enforcement of sections 409(a) and (d) of 
the FD&C Act. Section 701(a) of the FD&C Act authorizes the Secretary 
to issue regulations for the efficient enforcement of the FD&C Act; 
under section 1003(d) of the FD&C Act (21 U.S.C. 393(d)), the Secretary 
is responsible for executing the FD&C Act, including section 701(a) of 
the FD&C Act, through the Commissioner of Food and Drugs.

V. Description of the Proposed Rule

    As discussed in section III.B.1 of this document, in light of the 
issues we have identified with the voluntary GRAS notification program, 
and the challenges posed by the changing U.S. food supply, we are 
proposing to require the submission of GRAS notices for the use of a 
human or animal food substance that is purported to be GRAS under the 
conditions of its intended use. Food substances include both 
ingredients (i.e., substances added directly to food) and food contact 
substances (i.e., substances added indirectly to food, such as 
migration from food packaging). In proposing these changes, FDA is (1) 
converting the current GRAS notification program from voluntary to 
mandatory; (2) identifying certain categories of exceptions from the 
requirement to submit a GRAS notice, including a time-limited option to 
make a streamlined submission to FDA for certain substances already in 
use in interstate commerce; and (3) identifying uses of substances that 
are not eligible to be the subject of a GRAS notice.
    We are also proposing to make conforming edits throughout part 170 
to reflect the change to a mandatory program; changes to our procedural 
regulations for a TOR exemption to reflect updated scientific guidance 
and to expand the scope of this exemption to cover uses of substances 
in food and FCSs generally, in addition to FCSs used in food contact 
articles; and other changes to make non-substantive edits. Several of 
these changes would support the Administration's goal of modernizing 
Federal regulations to eliminate outdated or unnecessary requirements 
and ensure there is flexibility to, for example, leverage new 
technology in the future to more efficiently fulfill regulatory 
requirements. In addition, we are proposing new definitions to help in 
the administration of a mandatory GRAS notification program and 
updating other definitions for clarity.

A. Proposed Revisions to Sec.  170.3--Definitions

    Our regulations, at Sec.  170.3 (21 CFR 170.3), define certain 
terms for use throughout part 170. Specifically, Sec.  170.3(m) defines 
food as including human food, substances migrating to food from food-
contact articles, pet food, and animal feed. Proposed Sec.  170.3(m) 
would revise the definition of food to include human food, substances 
migrating to food from food-contact articles, and animal food. The term 
``animal food'' would update ``pet food, and animal feed'' and would 
align with the use of the term ``animal food'' within our regulations 
in part 507 (21 CFR part 507) (see Sec.  507.3) and proposed changes to 
part 570 (see section V.Q of this document).
    Proposed Sec.  170.3(p) would define ``We, our, us, and FDA'' to 
mean the Food and Drug Administration. While our regulations, at Sec.  
170.203, define ``We, our, and us'' as the ``United States Food and 
Drug Administration'' for use in Subpart E--Generally Recognized as 
Safe (GRAS) Notice, these terms are not defined in Sec.  170.3 to apply 
more generally to part 170. We propose adding ``FDA'' to the list of 
terms that would mean the Food and Drug Administration. This change 
would establish these terms for use throughout part 170.

B. Proposed Revisions to Sec.  170.30--Eligibility for Classification 
as GRAS

    Our regulations, at Sec.  170.30, describe the criteria for 
determining if a substance is eligible to be classified as GRAS. 
Specifically, Sec.  170.30(a) outlines the general criteria for GRAS 
status, in accordance with section 201(s) of the FD&C Act, and provides 
that general recognition of safety may be based only on the views of 
experts qualified by scientific training and experience to evaluate the 
safety of substances directly or indirectly added to food. GRAS status 
may be based on scientific procedures (see Sec.  170.30(a)(1)) or for a 
substance used in food before January 1, 1958, through experience based 
on common use in food (see Sec.  170.30(a)(2)). Our regulations, at 
Sec.  170.30(b) and (c), further explain the elements of the general 
criteria for GRAS status, and Sec.  170.30(d) through (l) discuss 
specific situations in relation to GRAS status.
    We are proposing revisions to Sec.  170.30(c), (e), and (i). Our 
regulations, at Sec.  170.30(c)(2), recommend that a person notify FDA 
if they conclude that

[[Page 51847]]

a use of a substance is GRAS through experience based on its common use 
in food outside of the U.S. Proposed Sec.  170.30(c)(2) would remove 
this recommendation, because the proposed rule would require a person 
to notify FDA about the purported GRAS status of a substance used in 
food before January 1, 1958, if that conclusion is through experience 
based on the substance's common use in food outside of the United 
States.
    Our regulations, at Sec.  170.30(e), provide some historical 
context for substances listed or affirmed as GRAS in parts 182, 184, or 
186 of this chapter and mention of the systematic review of such 
substances that FDA conducted beginning in 1969. Proposed Sec.  
170.30(e) would remove those discussions because they are no longer 
necessary.
    Our regulations, at Sec.  170.30(i), state that if a substance is 
affirmed as GRAS in part 184 or part 186 with no limitation other than 
good manufacturing practice, then it is regarded as GRAS if its 
conditions of use are not significantly different from those reported 
in the regulation as the basis on which the GRAS status of the 
substance was affirmed. If the conditions of use are significantly 
different, then the use of the substance may not be GRAS, and a 
manufacturer may not rely on the regulation as authorizing the use but 
must independently establish that the use is GRAS or must use the 
substance in accordance with a food additive regulation. Proposed Sec.  
170.30(i) would divide the provision into Sec.  170.30(i)(1) and (i)(2) 
for clarity, as these provisions cover different circumstances. 
Proposed Sec.  170.30(i)(1) would contain the concept that a substance 
will be regarded as GRAS if the conditions of use are not significantly 
different from those reported in the regulation (i.e., part 184 or part 
186). A mandatory GRAS notice would not be required for substances that 
fall within the scope of proposed Sec.  170.30(i)(1) (see proposed 
Sec.  170.205(b)(3)). Proposed Sec.  170.30(i)(2) would contain the 
concept that if the conditions of use of a substance are significantly 
different, the regulation in part 184 or part 186 may not be relied on 
as authorizing such use. In this latter situation, a GRAS notice would 
need to be submitted to FDA that covers the conclusion that a substance 
is GRAS under the conditions of its intended use if relevant safety 
information is generally available or a food additive petition could be 
submitted if there is not an existing food additive regulation to cover 
such use. Together, proposed Sec.  170.30(i)(1) and (i)(2) would 
clarify the circumstances when our regulations in part 184 or part 186 
can be relied on to regard a substance as GRAS under the conditions of 
its intended use.

C. Proposed Revisions to Sec.  170.38--Determination of Food Additive 
Status

    The proposed rule would amend Sec.  170.38 (21 CFR 170.38) to 
remove unnecessary provisions and add new provisions to clarify the 
steps we may take when we determine that a substance is not GRAS under 
the conditions of its intended use.
    Our regulations, at Sec.  170.38(a), provide for the Commissioner 
to publish a notice in the Federal Register determining that a 
substance is not GRAS under the conditions of its intended use if, 
after proposing that a substance is entitled to affirmation as GRAS 
under the conditions of its intended use, the Commissioner evaluates 
the comments and concludes that there is a lack of convincing evidence 
that the substance is GRAS under the conditions of its intended use 
(see Sec.  170.35). The proposal would amend Sec.  170.38(a) to remove 
the reference to publishing a notice in the Federal Register because 
FDA does not necessarily publish a notice when making such a 
determination. However, even though we may not publish a notice in the 
Federal Register, we would still make public the basis for our 
determination that the substance is not GRAS under the conditions of 
its intended use and is a food additive subject to section 409 of the 
FD&C Act. Proposed Sec.  170.38(a) would retain the concept that when a 
substance is determined to not be GRAS under the conditions of its 
intended use and would instead be a food additive, the substance and 
its use or intended use are subject to section 409 of the FD&C Act. A 
substance subject to section 409 of the FD&C Act would require the 
issuance of a food additive regulation, or an effective FCN in the case 
of an FCS, for its use as a food additive to be authorized.
    Our regulations, at Sec.  170.38(b), provide for the Commissioner, 
on his own initiative or on the petition of any person pursuant to part 
10 of this chapter, to issue a notice in the Federal Register proposing 
that a substance is not GRAS under the conditions of its intended use 
and is a food additive subject to section 409 of the FD&C Act; receive 
comments; and, upon evaluation of all comments, publish a notice in the 
Federal Register as to whether the substance's conditions of intended 
use are GRAS. Proposed Sec.  170.38(b) would clarify that this 
paragraph applies to substances listed or affirmed as GRAS in parts 
182, 184, or 186. We also propose other non-substantive edits for Sec.  
170.38(b)(1) and (b)(2) (see section V.O of this document for further 
discussion). Proposed Sec.  170.38(b)(3) would also provide that if FDA 
concludes that there is a lack of convincing evidence that the 
substance is GRAS under the conditions of its intended uses, FDA will 
amend or repeal the relevant regulation. We propose removing language 
stating that we will evaluate all comments received. As we would 
consider comments in response to a published proposal, this language is 
unnecessary.
    Our regulations, at Sec.  170.38(c), state that a Federal Register 
notice determining that a substance is a food additive must provide the 
use of the food additive in food or food contact substances and that we 
may promulgate a food additive regulation governing the additive's use, 
an interim food additive regulation governing the additive's use, 
require discontinuation of the additive's use, or adopt any combination 
of the above for different uses or levels of use of the additive. 
Proposed Sec.  170.38(c) would replace the discussion of what a Federal 
Register notice must contain (because the discussion is unnecessary as 
sections 409(c) and (d) of the FD&C Act already describe the contents 
of a food additive regulation) and would provide that, for uses of a 
substance for which FDA has issued a no questions letter (see proposed 
Sec.  170.203 and section V.E of this document for further discussion) 
in response to a GRAS notice, FDA may send the notifier questions about 
their GRAS conclusion in accordance with Sec.  170.265(c). Under 
proposed Sec.  170.38(c), if we determine that a substance is not GRAS 
under the conditions of its intended use (e.g., we receive information 
that calls into question a notifier's GRAS conclusion), FDA would make 
public the basis for this determination and update or rescind the no 
questions letter. This provision would pertain to GRAS conclusions 
received through the current voluntary GRAS notification program and 
the proposed mandatory GRAS notification program, if finalized.
    Our regulations, at Sec.  170.38(d), provide that if we are aware 
of a prior sanction for use of a substance, FDA will concurrently 
propose a separate regulation for such use. We propose to replace Sec.  
170.38(d), because the proposal of a regulation based on prior sanction 
for use of the substance would be covered by proposed Sec.  170.30(e). 
Instead, the proposed rule would create a new paragraph (d) to cover 
uses of substances not covered by proposed paragraphs (b) or (c) (i.e., 
uses of substances not covered by a regulation or a GRAS notice but 
which exist in

[[Page 51848]]

interstate commerce). If FDA makes a determination that uses of such 
substances are not GRAS, we would make public the basis for this 
determination. The fact that FDA has not made such a determination for 
a specific substance does not mean that the substance is GRAS under the 
conditions of its intended use.

D. Proposed Revisions to Sec.  170.39--Threshold of Regulation (TOR) 
for Substances Used in Food or as a Food Contact Substance

    Our regulations, at Sec.  170.39 (21 CFR 170.39), allow for an 
exemption from regulation for a substance used in food contact articles 
(e.g., food packaging or food processing equipment) that migrates or, 
that may be expected to migrate, into food if such substance meets the 
TOR criteria, as outlined in Sec.  170.39(a)(1) through (a)(4). These 
criteria include that the substance has not been shown to be a 
carcinogen and data supporting the resultant dietary concentration will 
be below 0.5 parts per billion.
    FDA established the TOR exemption process for food contact uses 
where migration is so trivial there are no concerns for safety. TOR 
submissions to FDA only require minimal data (e.g., identity, dietary 
exposure) to demonstrate the safe use of a substance. A full safety 
narrative is not required for a TOR submission. The scientific basis 
for the TOR is FDA's determination that very low dietary exposure 
presents no meaningful safety concern. Analysis of existing 
toxicological data allows FDA to identify a dietary exposure threshold 
for safety under certain criteria (see 60 FR 36582, July 17, 1995).
    We propose revising the title of Sec.  170.39 to ``Threshold of 
regulation for substances used in food or as a food contact 
substance.'' We propose amending Sec.  170.39(a) to provide that any 
substance used in food (both directly or indirectly added to food) will 
be exempted from regulation as a food additive or from the GRAS 
notification requirement under Sec.  170.205, if it meets the TOR 
criteria (see proposed 170.39(a)(1) through (a)(3)), which demonstrate 
safe use (i.e., the substance is present in foods at levels that result 
in no appreciable risk to human health). This would be true regardless 
of whether the use of the substance directly or indirectly resulted in 
it becoming a component of food. Therefore, both direct and indirect 
uses of a substance would be appropriately handled through the TOR 
process.
    We propose other changes throughout Sec.  170.39 to consistently 
reflect the expansion of the TOR exemption program to include 
substances used in food or as food contact substances and remove 
language specific to food contact articles (see proposed Sec.  
170.39(c)(2), (c)(3), (c)(4)(i) through (c)(4)(iv), (e), and (g)). 
Additionally, in several provisions, we propose amendments to reference 
GRAS substances, the GRAS notification requirement, and the GRAS notice 
program, given the proposed expansion of the TOR provisions to cover 
uses in food and as FCSs generally, that fall under the GRAS exception 
to the food additive definition of section 201(s) of the FD&C Act, as 
well as the FCN program, where applicable (see proposed Sec.  
170.39(b), (c), and (e)). We note that a substance that meets the TOR 
criteria can fall outside the definition of a food additive as defined 
by section 201(s) of the FD&C Act if such substance, under the 
conditions of its intended use, is GRAS. In such situations, a 
manufacturer or supplier may submit a TOR request as specified under 
proposed Sec.  170.39 and, if the intended use of a substance is the 
subject of a granted TOR exemption under Sec.  170.39, would meet an 
exception to submitting a mandatory GRAS notice under proposed Sec.  
170.205(b)(5). The TOR process is specifically tailored to handle the 
submission of data related to the use of substances that meet the TOR 
criteria, and we therefore recommend that industry use the TOR process 
for the intended use of a food substance that is purported to be GRAS 
and meets the TOR criteria.
    We propose revising Sec.  170.39(a) to update scientific 
terminology and reflect updated approaches to account for the 
assessment of cancer risk of carcinogenic compounds. Our regulation, at 
Sec.  170.39(a)(2)(i), states that the use in question must result in a 
dietary concentration of the FCS at or below 0.5 parts per billion 
corresponding to dietary exposure levels at or below 1.5 micrograms per 
person per day (based on a diet of 1,500 grams of solid food and 1,500 
grams of liquid food per person per day). Proposed Sec.  
170.39(a)(2)(i) would reflect updated approaches to determining 
exposure that accounts for differences in total dietary consumption and 
body weight of different subpopulations; the proposed revision from the 
dietary concentration of 0.5 parts per billion currently specified in 
our regulations to an estimated daily intake of 0.025 micrograms per 
kilogram bodyweight per day normalizes exposure across subpopulations, 
ensuring an equivalent level of safety for all subpopulations (Ref. 
38). We would make corresponding edits in proposed Sec.  170.39(a)(1), 
(c)(3) through (c)(5), (e), and (g).
    Additionally, our regulations at Sec.  170.39(a)(1) state that a 
substance must not contain a carcinogenic impurity or, if it does, it 
must not contain a carcinogenic impurity with a TD50 value 
of less than 6.25 milligrams per kilogram bodyweight per day. Proposed 
Sec.  170.39(a)(1) would update this requirement to reflect equivalent 
updated approaches to assessment of cancer risk and scientific 
terminology and state that the substance, if it contains a carcinogenic 
impurity, must not contain a carcinogenic impurity with a lifetime 
cancer risk greater than one in one million, when calculated using a 
TD50 value or another approach based on chronic feeding 
studies reported in the scientific literature or otherwise available to 
FDA, when present in the diet at 0.025 micrograms per kilogram 
bodyweight per day. In the parenthesis that follows, we propose 
clarifying that a TD50 of 6.25 milligrams per kilogram 
bodyweight per day equates to a lifetime cancer risk of less than one 
in one million when the impurity is present in the diet at 0.025 
micrograms per kilogram bodyweight per day. This demonstrates that the 
proposed revision results in an equivalent level of safety to that 
currently specified in our regulations. We would make corresponding 
edits in proposed Sec.  170.39(c)(5).
    Our regulations, at Sec.  170.39(a)(3), state that a substance used 
in a food contact article that migrates, or that may be expected to 
migrate, into food will be exempted from regulation as a food additive 
because it becomes a component of food at levels that are below the 
threshold of regulation if the substance has no technical effect in or 
on the food to which it migrates. We propose removing Sec.  
170.39(a)(3) because it is focused on food contact articles and would 
thus be inconsistent with our proposed change to expand the regulation 
to include substances added to food, and FCSs generally, that meet the 
criteria for exemption. We would also renumber existing Sec.  
170.39(a)(4) as Sec.  170.39(a)(3).
    Our regulations, at Sec.  170.39(b), state that we reserve the 
right to decline to grant an exemption in those cases in which 
available information establishes that the proposed use may pose a 
public health risk. The rule also states that we will provide the 
reasons for our decision to decline to grant an exemption in our 
response to the ``requestor.'' Proposed Sec.  170.39(b) would clarify 
that the ``requestor'' is the person who submits the request to exempt 
a use of a

[[Page 51849]]

substance from regulation as a food additive or from the GRAS 
notification requirement. These proposed changes align with the 
proposed expansion of TOR and the proposed changes to the GRAS 
notification program (see proposed Sec.  170.205).
    Our regulations, at Sec.  170.39(c), describe the contents of a 
request to exempt a use of a substance from regulation as a food 
additive. For example, under Sec.  170.39(c), the request must include 
three copies. Under Sec.  170.39(c)(1), the request must contain the 
chemical composition of the substance for which the request is being 
made, including, whenever possible, the chemical's name in accordance 
with the current Chemical Abstract Service (CAS) nomenclature 
guidelines and a CAS registry number if available. Proposed Sec.  
170.39(c) would clarify that a request under this section may be for 
FDA to exempt a use of a substance from regulation as a food additive 
or from the proposed GRAS notification requirement under Sec.  170.205. 
The proposed change would expand the provision to include the proposed 
mandatory GRAS notification requirement (see proposed Sec.  170.205(a)) 
and remove the requirement to submit three copies of the request, as 
submission in triplicate is no longer efficient or necessary.
    Our regulations, at Sec.  170.39(d), specify where data to be 
reviewed under this section must be submitted. Proposed Sec.  170.39(d) 
would require electronic submission of the data through HFP's 
Centralized Online Submission Module (COSM). Electronic submission of 
the data would make our administration of the TOR exemption process 
more efficient. Proposed Sec.  170.39(d) would also include an 
opportunity to request a waiver from the requirement to electronically 
submit the data through COSM. We are aware that electronic submission 
may not be available to every requestor, and thus, we are proposing 
that a requestor may request a waiver from the electronic data 
submission requirement from HFP's Office of Pre-Market Additive Safety.
    Our regulations, at Sec.  170.39(e), state that FDA will inform the 
requestor by letter whether the specific use is exempt from regulation 
as a food additive and that FDA will maintain a list of substances 
exempt from regulation as food additives on display at the Dockets 
Management Staff. Such list would include the name of the company that 
made the request, the chemical name of the substance, the specific use 
for which it has received an exemption from regulation as a food 
additive, and any appropriate limitations on its use, but it will not 
include trade names. Proposed Sec.  170.39(e) would remove reference to 
informing the requestor ``by letter'' whether the use is exempt or not 
from regulation as a food additive or from the GRAS notification 
requirement under Sec.  170.205. This change would provide flexibility 
to ensure we can leverage current and future technology to communicate 
information to the requestor and the public. Proposed Sec.  170.39(e) 
would also state that FDA will maintain a ``publicly available'' list 
of substances and their uses that are exempted from regulation as food 
additives or from the GRAS notification requirement under Sec.  
170.205. The proposed revision would remove language which provides 
that the list of substances and their use will be on display at the 
Dockets Management Staff and what the list will include. We are 
proposing these changes to maintain flexibility in how we provide 
information to a requestor and the public.
    We propose removing Sec.  170.39(f) which provides that if a 
request for an exemption from regulation as a food additive is not 
granted, the requestor may submit a petition for reconsideration to FDA 
in accordance with Sec.  10.33 (21 CFR 10.33). Paragraph (f) is 
unnecessary because our existing regulations at Sec.  10.33, 
``Administrative reconsideration of action,'' establish a process for 
interested persons to request reconsideration. Although it would no 
longer be specified in Sec.  170.39, under Sec.  10.33 the opportunity 
to seek reconsideration is available to a requestor that is denied a 
request for an exemption from regulation. We would renumber existing 
Sec.  170.39(g) as Sec.  170.39(f).
    Our regulations, at Sec.  170.39(h), state that guidance documents 
to help a requestor prepare a submission seeking exemption from the 
food additive regulations are available from FDA's Office of Food 
Additive Safety. The rule also encourages interested persons to obtain 
specific guidance from FDA on protocols to be used for obtaining 
migration data, on validation of analytical methods used to quantify 
migration levels, on procedures used to relate migration data to 
dietary exposures, and on any other issue. The proposed rule would 
remove Sec.  170.39(h) because FDA guidance documents are publicly 
available online, as well as through HFP, generally. As such guidance 
and recommendation language is not information we usually include in 
our regulations, removing it would streamline the provision.

E. Proposed Revisions to Sec.  170.203--Definitions Pertaining to GRAS 
Notices

    Our regulations, at Sec.  170.203, provide definitions that are 
applicable throughout Subpart E--Generally Recognized as Safe (GRAS) 
Notice. Proposed Sec.  170.203 would remove introductory language, as 
well as the definition of ``We, our, and us;'' amend the definitions of 
``GRAS'' and ``GRAS notice'' with clarifying edits; and establish 
definitions for ``Inventory'' and ``No questions letter.'' We propose 
removing the introductory language, which states ``The definitions and 
interpretations of terms in Sec.  170.3 apply to such terms when used 
in this subpart. The following definitions also apply.'' This language 
is unnecessary, as the introductory language of Sec.  170.3 makes clear 
that the definitions listed in Sec.  170.3 apply throughout part 170. 
The definitions in proposed Sec.  170.3 would continue to apply to 
subpart E of part 170, as well as to the other subparts. As discussed 
in section V.A of this document, we propose moving the definition of 
``We, our, and us'' to Sec.  170.3 so that these terms can apply 
throughout part 170.
    In the definition of ``GRAS,'' we propose adding a cross-reference 
to Sec.  170.3(i), which defines ``safe or safety.'' Our regulations, 
at Sec.  170.203, explain the acronym ``GRAS,'' but they do not provide 
a tie to how we define ``safe.'' Providing a cross-reference to Sec.  
170.3(i) would connect the explanation of the GRAS acronym with the 
definition of ``safe or safety'' in our regulations.
    In the definition of ``GRAS notice,'' we propose to cross-reference 
Sec.  170.205, ``Opportunity to submit a GRAS notice,'' in relation to 
``a submission'' and to revise ``not subject to the premarket approval 
requirements'' to read ``not subject to the premarket review and 
approval requirements for food additives under section 409 of the Act'' 
for clarity.
    We propose establishing definitions for ``Inventory'' and ``No 
questions letter,'' as we use these terms in proposed Sec.  170.275 (21 
CFR 170.275) and Sec.  170.205, respectively. ``Inventory'' would mean 
an online repository where FDA makes public certain information related 
to GRAS notices. In proposed Sec.  170.275(b) (see section V.K of this 
document for further discussion), we state that we will make the 
information included in Sec.  170.275(b)(1) through (3) available to 
the public through its inclusion in the inventory. We propose keeping 
the term ``inventory'' generic to allow for flexibility, because the 
name of the inventory or the location where

[[Page 51850]]

we house the inventory might evolve over time. This information is 
currently housed in a searchable database entitled ``GRAS Notices'' 
(Ref. 3).
    As discussed in the 2016 GRAS final rule, we established at least 
three categories of response letters during the interim pilot program, 
with ``No questions letter'' being one category (81 FR 54960 at 55014). 
We stated that the content of these categories of response letters has 
evolved over time and may continue to evolve; therefore, we did not 
specify any detail about the nature of our responses in our regulations 
(id.). Under the current voluntary GRAS notification program, a typical 
no questions letter makes clear that: (1) It is the information that is 
provided by the notifier that forms the basis for our response, and 
that the notifier (rather than FDA) is responsible for the conclusion 
of GRAS status; (2) our response must be considered in context based on 
the knowledge and information available to us at a point in time, 
because scientific knowledge and information about a particular 
ingredient can evolve and sometimes change; and (3) our response is not 
an affirmation of GRAS status of the notified substance under the 
conditions of its intended use in accordance with Sec.  170.35.
    Proposed Sec.  170.203 would define ``No questions letter'' as a 
letter from FDA, sent in response to a GRAS notice, which states that, 
based on the information the notifier provided, as well as other 
information available to us, we have no questions at this time 
regarding the notifier's conclusion that the notified substance is GRAS 
under the conditions of its intended use. We also propose including 
language to clarify that a no questions letter is neither an 
affirmation by FDA that the notified substance is GRAS for its intended 
conditions of use under Sec.  170.35, nor a published finding under 
section 721(b)(4) of the FD&C Act, which pertains to the premarket 
review and approval process for color additives, declaring the use of 
such substance exempt from the term ``food additive'' because of its 
being GRAS. Establishing a definition in our regulations for the no 
questions letter would be appropriate and necessary, as we propose to 
include an exception to the proposed requirement to submit a GRAS 
notice that is based off the existence of a no questions letter (see 
proposed Sec.  170.205 and section V.F of this document for further 
discussion).
    We also discussed two other categories of response letters in the 
2016 GRAS final rule (81 FR 54960 at 55014 through 55015). We noted 
that it is possible that in the future a response to a GRAS notice may 
not fit squarely within one of the current categories of response 
letters. In addition to the proposed definition for no questions 
letter, we also propose establishing definitions for cease to evaluate 
letter and insufficient basis letter (see section V.M.1 of this 
document). However, we are not proposing to establish these categories 
of response letters as the only response letters FDA might send in 
response to a GRAS notice.

F. Proposed Sec.  170.205--Creation of a Mandatory GRAS Notification 
Program

    Our regulations, at Sec.  170.205, provide that any person may 
voluntarily notify FDA of a view that a substance is not subject to the 
premarket review and approval requirements of section 409 of the FD&C 
Act based on that person's conclusion that the substance is GRAS under 
the conditions of its intended use. As discussed in section III of this 
document, we propose moving from the current voluntary GRAS 
notification program to a framework under which GRAS notices would be 
mandatory with certain limited exceptions. This change would lead to 
increased transparency about substances that are added to food, 
enabling FDA to regulate the safety of food substances more effectively 
and efficiently; determine if the use of a substance constitutes a food 
additive use that is subject to the premarket review and approval 
requirements of section 409 of the FD&C Act; and possibly identify 
instances where a potentially unsafe food additive is used in food, so 
we can take action as appropriate. Therefore, we propose revising the 
title of Sec.  170.205 from ``Opportunity to submit a GRAS notice'' to 
``Submission of a GRAS notice.''
1. Mandatory GRAS Notice Submission
    The proposed rule would create a new Sec.  170.205(a) to provide 
that any person introducing a substance into interstate commerce under 
the GRAS provision of section 201(s) of the FD&C Act must notify FDA of 
the basis for their conclusion that the substance is GRAS under the 
conditions of its intended use. This would include substances already 
in the food supply and those being marketed for food use for the first 
time. Proposed Sec.  170.205(a) would replace the current voluntary 
GRAS notification program, under which any person may, but is not 
required to, notify FDA of a view that a substance is GRAS under the 
conditions of its intended use. As discussed elsewhere in this 
document, our experience administering the voluntary GRAS notification 
program, particularly in the last decade, has demonstrated a need for 
us to require the submission of GRAS notices to provide FDA with 
information to help us to better identify potentially unsafe substances 
used in food, thereby enabling FDA to take action as appropriate and 
regulate the safety of food substances more effectively. Changes in our 
country's food supply during this same period further support the need 
to require the submission of GRAS notices. Among other things, 
requiring the submission of GRAS notices would increase transparency 
about substances in the U.S. food supply that are purported to be GRAS 
under the conditions of their intended use.
    Uses of substances that are excepted from the definition of a food 
additive under section 201(s)(1) through (6) of the FD&C Act cannot be 
the subject of a GRAS notice. Specifically, the term ``food additive'' 
does not include: (1) A pesticide chemical residue in or on a raw 
agricultural commodity or processed food; (2) a pesticide chemical; (3) 
a color additive; (4) any substance used in accordance with a sanction 
or approval granted prior to September 6, 1958, pursuant to the FD&C 
Act, the Poultry Products Inspection Act (Pub. L. 85-172, 71 Stat. 441) 
or the Federal Meat Inspection Act (Pub. L. 59-382, 34 Stat. 669); (5) 
a new animal drug; or (6) an ingredient described in section 201(ff) of 
the FD&C Act in, or intended for use in, a dietary supplement (section 
201(s)(1) through (6) of the FD&C Act). As such categories are excepted 
from the definition of ``food additive'' in section 201(s) of the FD&C 
Act, they are not eligible for classification as GRAS under the GRAS 
provision included in the definition of ``food additive'' (see proposed 
Sec.  170.205(c)).
    Proposed Sec.  170.205(a) would also provide that if the conditions 
of use meet the definition of an FCS in accordance with Sec.  
170.3(e)(3), then a manufacturer or supplier may submit an FCN as 
specified under Sec.  170.100 (21 CFR 170.100) instead of a GRAS 
notice. An FCN refers to a premarket notification for an FCS. Section 
409(h)(3)(A) of the FD&C Act states that the FCN process shall be 
utilized for authorizing the marketing of food additives that are FCSs, 
except where the Secretary determines that the submission and review of 
a food additive petition is necessary to provide adequate assurance of 
safety, or where FDA and any manufacturer or supplier agree that a 
petition may be submitted (see S. Rept. No. 105-43, 105th Cong., 1st 
sess. 46 (1997); H. Rept. 105-306, 105th Cong., 1st sess. 19 (1997)). 
FCNs are required only for those FCSs that are

[[Page 51851]]

food additives as defined by section 201(s) of the FD&C Act (21 U.S.C. 
321(s)) and that are not otherwise authorized under section 409 of the 
FD&C Act. We note, however, that an FCS can fall outside the definition 
of a food additive as defined by section 201(s) of the FD&C Act if such 
substance, under the conditions of its intended use, is GRAS. In such 
situations, a manufacturer or supplier may submit either an FCN as 
specified under Sec.  170.100 or a mandatory GRAS notice under proposed 
Sec.  170.205. However, we recognize that the FCN process is 
specifically tailored to handle the submission of data related to FCSs, 
and we therefore recommend that industry use the FCN process for an FCS 
that is purported to be GRAS under the conditions of its intended use.
    For uses of substances that are required to be the subject of a 
GRAS notice, FDA would consider as a factor in its prioritization of 
food substances for post-market review whether the notification 
requirement has been met concerning the substance's conditions of 
intended use pursuant to Sec.  170.265(a) (which relates to what FDA 
will do with a GRAS notice). As discussed in section II.B.3 of this 
document, we are proposing the GRAS notification requirement to gain 
information about purported GRAS uses of substances on the market, 
including some substances and uses into which we might not otherwise 
have insight. Because the failure to comply with the proposed GRAS 
notification requirement would impede FDA's efforts in this regard, as 
well as our ability to carry out our statutory responsibility to 
prohibit the use of unsafe additives in food, noncompliance with 
proposed Sec.  170.205(a) for uses of substances that are required to 
be the subject of a GRAS notice would be a factor in FDA's 
prioritization of food substances for post-market review.
    As we have received a significant number of submissions during the 
voluntary GRAS notification program that we did not file as GRAS 
notices (e.g., because the submission did not contain all parts of a 
GRAS notice that are required by our regulations), we are proposing 
that the mere submission of materials for a GRAS notice to FDA would 
not be sufficient to meet the notification requirement. Rather, under 
proposed Sec.  170.265(a)(2), FDA would consider the notification 
requirement of proposed Sec.  170.205 to be met upon FDA's filing of a 
submission as a GRAS notice, except as provided for in proposed Sec.  
170.265(b)(3).
    Upon receipt of a submission, we would continue to follow our 
existing procedures to conduct an initial evaluation of the submission 
before determining whether to file it as a GRAS notice, but we are 
proposing that this initial evaluation will be completed within 45 days 
(see proposed Sec.  170.265(a)(1)). During this preliminary assessment 
to determine whether the submission is adequate to file, FDA is not 
evaluating the GRAS status of the substance's conditions of intended 
use, and the filing of a GRAS notice does not mean that the substance 
that is the subject of the GRAS notice is GRAS under the conditions of 
its intended use. Upon the filing of a GRAS notice, we will then 
evaluate the notifier's basis for concluding that the criteria for GRAS 
status are satisfied.
    Importantly, the proposed GRAS notification program generally, and 
proposed Sec.  170.205(a), do not establish a premarket review program 
for purportedly GRAS substances. As explained elsewhere in this 
document, the FD&C Act allows a person to introduce a substance into 
interstate commerce if the substance is GRAS under the conditions of 
its intended use (see sections 201(s) and 409 of the FD&C Act). Thus, a 
company may continue marketing a purported GRAS substance before 
submitting a GRAS notice or after submitting a GRAS notice before it is 
filed by FDA. Similarly, a company may reach a GRAS conclusion about a 
new use of a substance and introduce the substance into interstate 
commerce before submitting a GRAS notice. However, the proposed GRAS 
notification program would assist FDA's post-market review of purported 
GRAS substances, enabling FDA to determine whether these substances are 
not GRAS and therefore require FDA review and approval under section 
409 of the FD&C Act.
2. Exceptions From Mandatory GRAS Notice Submission
    There may be circumstances where requiring the submission of a GRAS 
notice would be unnecessary or unwarranted.
    a. No questions letter. Proposed Sec.  170.205(b)(1) would create 
an exception from the GRAS notice submission requirement when an 
existing no questions letter covers the substance under the conditions 
of its intended use. There is no provision in the FD&C Act providing a 
notifier exclusivity for the use of a substance on the basis that it is 
GRAS under the conditions of its intended use. As discussed in section 
V.E of this document, a no questions letter is a category of response 
letter that FDA may send to the notifier in response to a GRAS notice 
(see also 81 FR 54960 at 55014). When a no questions letter exists and 
covers a substance under the conditions of its intended use, that means 
that we previously received a GRAS notice pertaining to the conditions 
of use of the substance, conducted a substantive evaluation of the GRAS 
notice, and had no questions at that time regarding the notifier's 
conclusion that the notified substance is GRAS under the conditions of 
its intended use (see proposed Sec.  170.203). Given this prior 
evaluation and assessment, if the conditions of use of a substance are 
the same as those that were the subject of a GRAS notice that received 
a no questions letter, we would not need to evaluate the GRAS status of 
the use of such substance.
    We note that a GRAS conclusion within a GRAS notice for which we 
issued a no questions letter may not apply to a use of a substance if 
the identity of, manufacturing process for, or the conditions of use 
(e.g., food categories, use levels, technical effect, specifications) 
of that substance are significantly different from those discussed in 
the GRAS notice that received the no questions letter response. For 
example, a substance may not be food grade following a manufacturing 
process change that introduces impurities into the substance. 
Therefore, a change in manufacturing process may alter the composition, 
and perhaps the toxicity, of the substance. If the use of a substance 
differs from the uses discussed in a GRAS notice that received a no 
questions letter response, it is the obligation of the manufacturer to 
demonstrate whether the substance is GRAS under the conditions of its 
intended use. The manufacturer may consult with FDA regarding this 
issue.
    In addition, we note that proposed Sec.  170.205(b)(1) would 
require that a no questions letter cover the conditions of use of a 
substance in order for the exception to apply. Thus, proposed Sec.  
170.205(b)(1) would not apply, and a GRAS notice would be required for 
the use of the substance, if pursuant to proposed Sec.  170.38(c), FDA 
later rescinded the no questions letter that pertained to the 
conditions of use of the substance.
    We considered whether to provide for an alternate procedure (e.g., 
abbreviated GRAS notice submission) for substances that exist in our 
GRAS notice inventory--e.g., when the use of a substance differs from 
the uses discussed in an existing GRAS notice that received a no 
questions letter or when there is a change in manufacturing process 
related to the

[[Page 51852]]

uses of a substance discussed in an existing GRAS notice that received 
a no questions letter. We have tentatively concluded that an alternate 
procedure is unnecessary, as notifiers currently are able to 
incorporate into a new GRAS notice data and information previously 
submitted to FDA (see 21 CFR 170.215). As we stated in the 2016 GRAS 
final rule (81 FR 54960 at 54988), we expect a notifier to provide a 
specific file number (e.g., for a GRAS notice) that contains the 
referenced data and information, and to identify the specific data and 
information in that file (rather than to broadly incorporate into a 
GRAS notice the entire file without explaining which data and 
information to incorporate). However, we invite comment on additional 
ways in which we could facilitate or make more efficient a notifier's 
ability to incorporate data and information already submitted to FDA 
into a new GRAS notice. We also invite comment on other specific 
scenarios for which FDA could consider providing an alternate procedure 
(e.g., abbreviated GRAS notice submission) or that FDA could consider 
to be covered by an existing no questions letter. Furthermore, as 
discussed in section V.Q of this document, we invite comment on this 
topic as it relates to substances that exist in our animal food GRAS 
notice inventory.
    b. Substance listed or affirmed as GRAS under the conditions of its 
intended use in parts 182, 184, or 186. Proposed Sec.  170.205(b)(2) 
would create an exception from the GRAS notice submission requirement 
for a substance that is listed or affirmed as GRAS under the conditions 
of its intended use in parts 182, 184, or 186. Where FDA has conducted 
rulemaking to list or affirm a substance as GRAS under the conditions 
of its intended use, we have already determined that such substance is 
GRAS for its intended use. Therefore, a GRAS notice would be 
unnecessary. If, pursuant to proposed Sec.  170.38(b), we later repeal 
the relevant regulation in parts 182, 184, or 186 that covered the 
conditions of use of a substance, or amended the relevant regulation 
such that it no longer covered the conditions of use of the substance, 
a GRAS notice would be required if the substance is introduced into 
interstate commerce under the GRAS provision of section 201(s) of the 
FD&C Act.
    c. Substance considered GRAS under the conditions of its intended 
use in accordance with Sec.  170.30(d) or proposed Sec.  170.30(i)(1). 
Proposed Sec.  170.205(b)(3) would create an exception from the GRAS 
notice submission requirement for a substance considered GRAS under the 
conditions of its intended use in accordance with Sec.  170.30(d) or 
proposed Sec.  170.30(i)(1). Our regulations, at Sec.  170.30(d), 
provide that a food ingredient of natural biological origin that has 
been widely consumed for its nutrient properties in the United States 
before January 1, 1958, without known detrimental effects, which is 
subject only to conventional processing as practiced before January 1, 
1958, and for which no known safety hazard exists, will ordinarily be 
regarded as GRAS without specific inclusion in parts 182, 184, or 186. 
Our regulations, at Sec.  170.30(i) (see proposed Sec.  170.30(i)(1)), 
provide that a substance that is affirmed as GRAS under the conditions 
of its intended use in part 184 or part 186 with no limitation other 
than good manufacturing practice shall be regarded as GRAS if its 
conditions of use are not significantly different from those reported 
in the regulation as the basis on which the GRAS status of the 
substance was affirmed. While such substances are not explicitly listed 
or affirmed as GRAS under the conditions of their intended use in our 
regulations, both provisions provide that such substances are generally 
to be regarded as GRAS if certain conditions are met. Requiring a GRAS 
notice for uses of substances already covered by Sec.  170.30(d) and 
proposed Sec.  170.30(i)(1) would similarly be unnecessary.
    d. Established FDA process. Proposed Sec.  170.205(b)(4) would 
create an exception from the GRAS notice submission requirement where 
we have considered the intended use of the substance through an 
established FDA process to evaluate the potential presence of 
unapproved food additives and documentation made publicly available by 
FDA through that process does not recommend or otherwise identify the 
need to submit a GRAS notice.
    FDA operates three processes for evaluating foods developed using 
innovative technologies to help developers ensure that resulting foods 
are safe and lawful prior to marketing. For foods from new plant 
varieties developed through biotechnology, HFP and CVM jointly offer 
Voluntary Premarket Consultations and Voluntary Premarket Meetings. For 
foods from cultured animal cells, HFP offers Animal Cell Culture 
Consultations. These processes are standardized, science-based, and 
provide transparency--we post information about the subjects of 
Voluntary Premarket Consultations, Voluntary Premarket Meetings, and 
Animal Cell Culture Consultations to FDA's website (Refs. 39 to 41). 
During these processes, we consider whether the food under 
consideration may require further review because it contains a 
substance that would be subject to the premarket review and approval 
requirements for food additives under section 409 of the FD&C Act or 
those for color additives under section 721 of the FD&C Act.
    A possible outcome is a recommendation that a substance undergo 
evaluation through a separate program (e.g., GRAS notification, FCN, 
food additive petition, or color additive petition). If the process 
concludes without FDA recommending or otherwise identifying the need 
for evaluation through a GRAS notice, we propose that a GRAS notice 
would not be required for anyone marketing the substance for the 
particular use that was reviewed because FDA was able to examine the 
intended use of the substance in food before it is introduced into 
interstate commerce. We note that if we were to recommend or otherwise 
identify the need for evaluation through a premarket review and 
approval program (e.g., FCN, food additive petition, or color additive 
petition), it would not be appropriate to introduce such a substance 
into the food supply under the GRAS provision of section 201(s) of the 
FD&C Act.
    FDA routinely conducts informal consultations with firms and 
advises on the regulatory status of substances added to food. Informal 
written statements, such as technical assistance, would not qualify for 
the exception in proposed Sec.  170.205(b)(4), because such 
documentation does not necessarily reflect the conclusion of a formal, 
standardized evaluation process providing for transparency. FDA also 
offers the Early Food Safety Evaluation Program for new non-pesticidal 
proteins produced by new plant varieties not intended to enter the food 
supply, but that might occur in food unintentionally at intermittent, 
low levels. This program would similarly not qualify for the exception 
in proposed Sec.  170.205(b)(4), because this process was developed to 
manage instances of unintended, low-level presence in food, not to 
resolve regulatory issues about the potential presence of unapproved 
food additives.
    e. TOR exemption. Proposed Sec.  170.205(b)(5) would create an 
exception from the GRAS notice submission requirement where the 
intended use of a substance is the subject of an exemption under the 
TOR process in Sec.  170.39. If the intended use of a substance is a 
subject of an exemption under the TOR process as proposed in Sec.  
170.39, it means that the substance is in foods or migrates into foods 
at levels that result in no

[[Page 51853]]

appreciable risk to human health. As such, the substance used in food 
or as a food contact substance is present in the diet at levels that 
are below the TOR. The TOR process allows these substances to undergo 
an abbreviated review process where we determine whether the specific 
use of the substance meets criteria ensuring that the intended use 
would pose no more than a negligible health risk. If we evaluated the 
specific use of a substance under TOR and granted an exemption, a 
mandatory GRAS notice would be redundant and unnecessary. Providing an 
exception in this circumstance would enable us to devote more time and 
resources to reviewing GRAS notices for uses of substances where there 
could be more pressing public health concerns.
    f. Effective premarket notification for an FCS. Proposed Sec.  
170.205(b)(6) would create an exception from the GRAS notice submission 
requirement where there is an effective premarket notification for an 
FCS which covers the substance under the conditions of its intended use 
and the substance in interstate commerce originates from the 
manufacturer or supplier listed in the effective FCN. As discussed 
elsewhere in this document, the FCN program may receive submissions 
that cover a food contact substance that is GRAS under the conditions 
of its intended use. If there is an effective FCN which covers the 
substance under the conditions of its intended use, a GRAS notice is 
not required. However, as the FCN program is limited to the use of a 
specific food contact-substance and to the specific manufacturer or 
supplier listed in the FCN (see section 409(h)(2)(C) of the FD&C Act 
and Sec.  170.100(a)), this exception from a mandatory GRAS notice 
submission would apply only for the manufacturer or supplier listed in 
the FCN. Therefore, if the substance under the conditions of its 
intended use is in interstate commerce through a different manufacturer 
or supplier than is listed in the FCN, this exception would not apply, 
and a GRAS notice submission would be required for the substance under 
the conditions of its intended use.
    g. Time-limited option to submit certain information to FDA. 
Proposed Sec.  170.205(b)(7) would create an exception from the GRAS 
notice submission requirement if certain information about the 
conditions of use of the substance is submitted to FDA (see proposed 
Sec.  170.305 (21 CFR 170.305), discussed in section V.M of this 
document) and the submission is included on a public list maintained by 
FDA, unless we issue a determination that a GRAS notice or a food 
additive petition must be submitted for the intended use of a 
substance. Thus, inclusion on the list would not represent a 
determination by FDA that the use of the substance is GRAS or does not 
require a food additive petition (see proposed Sec.  170.305(d) (21 CFR 
170.305(d))).
    This proposed exception from having to submit a GRAS notice, in 
conjunction with proposed Sec.  170.305, provides a pathway, for a 
time-limited period, to submit certain information to FDA for a 
substance that was introduced into interstate commerce before the 
effective date of any final rule resulting from this rulemaking based 
on an independent conclusion of GRAS status. As many persons have 
relied on section 201(s) of the FD&C Act and our existing regulations 
to market these substances and given the considerable resources it 
takes us to evaluate and respond to a GRAS notice, providing this 
alternate streamlined submission pathway would enable FDA to gather 
information about these substances and their conditions of use while 
not overly burdening our administrative resources. We would use the 
information we gather to evaluate through post-market activities 
whether the use of substances should be re-evaluated, including whether 
a GRAS notice regarding the conditions of use of a substance must be 
submitted (see proposed Sec.  170.305(d) and section V.M. of this 
document for further discussion).

G. Proposed Revisions to Sec.  170.210--Mandatory Electronic Submission 
of GRAS Notices to FDA

    Our regulations, at Sec.  170.210 (21 CFR 170.210), specify where a 
GRAS notice is to be submitted, the format, and the organization of a 
GRAS notice. Proposed Sec.  170.210 would require electronic submission 
of GRAS notices through HFP's Centralized Online Submission Module 
(COSM). Requiring the electronic submission of GRAS notices would make 
our administration of the GRAS notification program more efficient. 
Requiring electronic submission of GRAS notices would reduce the 
resources needed to disseminate a submission among FDA staff, decrease 
the likelihood of poor-quality paper scans or lost documents, and 
ensure submissions are transmitted in a timely fashion, thus making our 
administration of the GRAS notification procedure more efficient.
    We propose the use of COSM for submission of mandatory GRAS 
notices. COSM is used to transmit not only voluntary GRAS notices, but 
also food and color additive petitions, FCNs, final biotechnology 
consultations, and more. COSM provides a real-time user interface to 
assist users in making submissions to HFP's program offices. FDA has 
worked with industry on transmitting the submission of GRAS notices in 
electronic format since 2010.
    Proposed Sec.  170.210 would also include the opportunity to 
request a waiver from the requirement to electronically submit a GRAS 
notice through COSM. We are aware that electronic submission may not be 
available to every notifier, and, thus, we are proposing that a 
notifier could send a request for a waiver from the requirement to 
submit a GRAS notice electronically to the Office of Pre-Market 
Additive Safety. If granted, a waiver would allow the notifier to 
submit a GRAS notice on paper.

H. Proposed Revisions to Sec.  170.220--Requirement To Submit English 
Translations of Material Included in a GRAS Notice

    Our regulations, at Sec.  170.220 (21 CFR 170.220), cover general 
requirements applicable to a GRAS notice. Proposed Sec.  170.220(c) 
would add a requirement that any material submitted in or referenced by 
a GRAS notice that is in a foreign language must be accompanied by an 
accurate and complete English translation. This requirement is 
comparable to the requirements in Sec.  170.100 and Sec.  171.1(a) (21 
CFR 171.1(a)) for data submitted in a premarket notification for an FCS 
and a food additive petition, respectively, and would facilitate our 
review of GRAS notice submissions.

I. Proposed Revisions to Sec.  170.250--Identification of Data and 
Information Exempt From Disclosure Under the Freedom of Information Act

    Our regulations, at Sec.  170.250 (21 CFR 170.250), describe what 
is to be included in Part 6 of a GRAS notice: Narrative. Specifically, 
Sec.  170.250(d) tells notifiers that they must, at the time of their 
submission, identify specific data and information that they view as 
exempt from disclosure under the Freedom of Information Act (FOIA; 5 
U.S.C. 552). Proposed Sec.  170.250(d) would clarify how we intend to 
handle data and information that is not identified as exempt under FOIA 
by stating that if a notifier's narrative does not identify data and 
information as exempt from disclosure under FOIA, we will consider such 
data and information to not be exempt from disclosure or that you have 
waived any claim of confidentiality. This proposed change would provide 
transparency to notifiers as to what data and information will be 
considered not exempt and subject to

[[Page 51854]]

public disclosure in accordance with part 20 (21 CFR part 20).
    Proposed Sec.  170.250(e) would require the notifier to explain how 
there could be a basis for a conclusion of GRAS status for any non-
public, safety related data and information that the notifier 
identifies as exempt from disclosure under FOIA despite the fact that 
qualified experts do not have access to such data and information. The 
proposed change would more clearly connect the explanation required by 
Sec.  170.250(e) with the data and information identified as exempt 
from disclosure under FOIA in Sec.  170.250(d).

J. Proposed Revisions to Sec.  170.265--Circumstance Where FDA Would 
Not Consider the Mandatory GRAS Notice Notification Requirement To Be 
Met

    Our regulations, at Sec.  170.265, outline what FDA does with a 
GRAS notice. Currently, we conduct an initial evaluation of a 
notifier's submission to determine whether to file it as a GRAS notice. 
There are no timing parameters for how long this initial evaluation 
takes. Proposed Sec.  170.265(a)(1) would add a 45-day timeframe to 
this initial evaluation of a submission to determine whether to file it 
as a GRAS notice. We recognize that, under the current voluntary GRAS 
notification program, the initial evaluation of a submission can be 
lengthy. Including timing parameters around our initial pre-filing 
evaluation would alleviate concerns about potential delays that might 
occur for these steps and provide more certainty about FDA's GRAS 
notification program. As we are proposing that the notification 
requirement of Sec.  170.205 will be met when we file a submission as a 
GRAS notice, we request comment on this proposed 45-day pre-filing 
period and other ways to reduce potential delays between receipt of a 
submission and filing of a GRAS notice.
    Our regulations, at Sec.  170.265(a)(2), provide that if FDA files 
a submission as a GRAS notice, we will send the notifier a letter that 
informs them of the date of filing; alternately, Sec.  170.265(a)(3) 
provides that if FDA does not file a submission as a GRAS notice, we 
will send the notifier a letter that informs them of this fact and 
provides our reasons for not filing the submission as a GRAS notice. We 
propose to amend Sec.  170.265(a)(2) and (a)(3) to state that we will 
send these letters within two business days of FDA making the decision 
to file or not file the submission as a GRAS notice. Including timing 
parameters around our sending of these filing decision letters would 
similarly alleviate potential concerns and provide more certainty about 
FDA's GRAS notification program. Proposed Sec.  170.265(a)(2) would 
also state that if we file a submission as a GRAS notice, we will 
consider the notification requirement of Sec.  170.205 to be met, 
except as provided by Sec.  170.265(b)(3). Proposed Sec.  170.265(a)(5) 
would clarify that we may contact a notifier with questions related to 
the notice, including about the data and information used to support a 
GRAS conclusion, during our evaluation of a GRAS notice. This new 
provision would help prevent confusion with the response that we send 
to a notifier based on our evaluation of a GRAS notice under Sec.  
170.265(b)(1).
    Our regulations, at Sec.  170.265(b)(1), state that, within 180 
days of filing plus an additional 90 days if needed, we will respond to 
a notifier based on our evaluation of a GRAS notice. If we need to 
extend the timeframe, we inform a notifier in writing of the extension 
as soon as practicable but no later than within 180 days of filing (see 
Sec.  170.265(b)(2)). Proposed Sec.  170.265(b)(1) would add a second 
90-day extension period, if necessary, and proposed Sec.  170.265(b)(2) 
would clarify that we will inform a notifier in writing of this second 
extension as soon as practicable but no later than the end of the 
initial 90-day extension. Given the expected increase in the number of 
GRAS notices if this rule is finalized, a second 90-day extension would 
provide FDA with the opportunity to complete timely evaluations. It 
would give us the time needed to consider amendments to a filed notice 
or any other information received from a notifier related to a GRAS 
submission. Further, allowing for a second 90-day extension may 
increase the potential for a successful evaluation outcome (i.e., 
issuance of a no questions letter). Informing the notifier about the 
need for a second extension by no later than the end of the initial 90-
day extension aligns with the current notification procedure for an 
extension of the 180-day evaluation period. We invite comment on the 
addition of a second 90-day extension to the 180-day evaluation period.
    Our regulations, at Sec.  170.265(b)(3), state that if a notifier 
asks us to cease to evaluate a GRAS notice, we will send the notifier a 
letter informing them of our decision regarding the request. Proposed 
Sec.  170.265(b)(3) would clarify that if FDA ceases to evaluate a GRAS 
notice, we will not consider the mandatory GRAS notification 
requirement under proposed Sec.  170.205 to be met. A GRAS notice for 
which we grant a cease to evaluate request for has the same effect as 
if we never received a GRAS notice for the intended use of a substance. 
Therefore, a notifier would not meet their obligation under proposed 
Sec.  170.205 to submit a mandatory GRAS notice if they: submit a GRAS 
notice, later request that FDA cease to evaluate their GRAS notice, and 
we grant such request. In such a case, the use of the substance that 
was the subject of the GRAS notice that we ceased to evaluate would not 
comply with the GRAS notification requirement until we filed a new GRAS 
notice pertaining to the substance's use.
    In other situations, after completing our review of a GRAS notice, 
we may not issue a no questions letter, and may instead issue a 
different response, for example, a letter stating that the notice does 
not provide sufficient information in support of a GRAS conclusion. A 
response stating that there is an insufficient basis for a GRAS 
conclusion would not mean that a notifier has failed to meet their 
obligation under Sec.  170.205 to submit a mandatory GRAS notice. 
However, such a response would be relevant to our determination of 
whether a food substance is an unapproved food additive under its 
conditions of use and would inform any post-market action against such 
a substance added to food.

K. Proposed Revisions to Sec.  170.275--Public Disclosure of a GRAS 
Notice

    Our regulations, at Sec.  170.275, cover public disclosure of GRAS 
notices. Specifically, Sec.  170.275(a)(1) states that even though 
submission of a GRAS notice is voluntary, it is considered a mandatory 
submission for purposes of its status under FOIA and FDA's public 
information requirements in part 20. Section 170.275(a)(2) states that 
the information is available for public disclosure in accordance with 
part 20 as of the date that we receive the GRAS notice. Proposed Sec.  
170.275(a) would reflect the change from a voluntary to a mandatory 
submission requirement for GRAS notices and combine the information in 
a single paragraph (a), thus eliminating the need for subparagraphs 
(a)(1) and (2).
    Our regulations, at Sec.  170.275(b), outline what information we 
will make readily accessible to the public. However, we do not specify 
a location where we make this information public. Proposed Sec.  
170.275(b) would clarify that we will make the information listed in 
Sec.  170.275(b)(1) through (3) accessible to the public through the 
inventory (as defined in proposed Sec.  170.203). We currently maintain 
this information in FDA's GRAS Notice Inventory, which is available on 
our website (Refs. 3 and 4). We intend to continue using this web page 
to share: (1) filed GRAS notices; (2)

[[Page 51855]]

any letters sent based on our evaluation of the notice (Sec.  
170.265(b)(1)) or subsequent letters regarding the notice (Sec.  
170.265(c)); and (3) any letters granting a cease to evaluate request 
(Sec.  170.265(b)(3)).
    We propose removing Sec.  170.275(c), which states that we will 
disclose all remaining data and information that are not exempt from 
public disclosure in accordance with part 20, because this language 
would be covered by proposed Sec.  170.275(a). Data and information 
which falls within the definitions of a trade secret or confidential 
commercial or financial information are not available for public 
disclosure (see part 20).

L. Proposed Revocation of Sec.  170.285--Disposition of GRAS 
Affirmation Petitions

    Our regulations, at Sec.  170.285 (21 CFR 170.285), cover how we 
handled filed GRAS affirmation petitions that were pending as of 
October 17, 2016 (the effective date of the GRAS final rule) as we 
transitioned to the current voluntary GRAS notification program. As 
there are no longer any pending GRAS affirmation petitions, and we have 
replaced the GRAS affirmation process with the voluntary GRAS 
notification program, this section is outdated. We propose removing 
Sec.  170.285 consistent with Executive Order 13563, ``Improving 
Regulation and Regulatory Review'' (76 FR 3821, Jan. 21, 2011), which 
requires agencies to periodically conduct retrospective analyses of 
existing regulations to identify those ``that may be outmoded, 
ineffective, insufficient, or excessively burdensome, and to modify, 
streamline, expand, or repeal them,'' accordingly.

M. Proposed Addition of Subpart F--Establishment of Definitions and 
Pathway for Submission of Certain Information During Time-Limited 
Option for Substances Introduced Into Interstate Commerce Under the 
GRAS Provision of Section 201(s) of the FD&C Act Before the Effective 
Date of a Final Rule

    We propose establishing a new subpart F, ``Submissions for 
Substances Introduced into Interstate Commerce Under the GRAS Provision 
of Section 201(s) of the Act Before [EFFECTIVE DATE OF THE FINAL 
RULE].'' The proposed subpart F would provide definitions that would 
apply only to subpart F (see proposed Sec.  170.303 (21 CFR 170.303)) 
and describe the time-limited option that firms can choose to 
participate in to qualify for an exception from the GRAS notice 
submission requirement under proposed Sec.  170.205(b)(7) (see proposed 
Sec.  170.305).
1. Definitions Applicable for Proposed Subpart F
    Proposed Sec.  170.303 would define ``Cease to evaluate letter,'' 
``GRAS,'' ``GRAS notice,'' ``Insufficient basis letter,'' and 
``Submitter.'' Our regulations reference that FDA may grant a 
notifier's request that we cease to evaluate a GRAS notice by sending a 
letter informing the notifier of our decision (Sec.  170.265(b)(3)). 
While we refer to these as cease to evaluate letters (see, e.g., 81 FR 
54960 at 55015), our regulations have not codified this term. Because 
proposed Sec.  170.305 would use this term (see section V.M.2 of this 
document), we propose to define ``Cease to evaluate letter'' to mean a 
letter from FDA granting a request to cease to evaluate a GRAS notice 
under Sec.  170.265(b)(3).
    We propose using the terms ``GRAS'' and ``GRAS notice'' in subpart 
F in the same way as we use these terms in subpart E; however, the 
definitions in Sec.  170.203 only apply to subpart E. Therefore, we 
propose including the same definitions for ``GRAS'' and ``GRAS notice'' 
in Sec.  170.303 so that these terms are defined for use in subpart F 
of part 170 and align with subpart E of part 170.
    Our regulations, at Sec.  170.265(b)(1), state that within 180 days 
of filing a GRAS notice, we will respond to a notifier by letter based 
on our evaluation of the notice. As discussed in the 2016 GRAS final 
rule, we established at least three categories of response letters 
during the interim pilot program--``Insufficient basis letter'' was one 
category (81 FR 54960 at 55014). The content of these categories of 
response letters has evolved over time and may continue to evolve; 
therefore, we did not specify any detail about the nature of our 
responses in our regulations (Id.). We propose in Sec.  170.303 to 
define ``Insufficient basis letter'' to mean a letter from FDA, sent in 
response to a GRAS notice, which states that, based on the data and 
information provided, as well as other available information, the 
notice does not provide a sufficient basis for a conclusion that the 
notified substance (as defined in Sec.  170.203) is GRAS under the 
conditions of its intended use. Establishing this definition is 
necessary because we propose that a submission under Sec.  170.305 is 
not allowed for any conditions of use of a substance that are the 
subject of an insufficient basis letter (see proposed Sec.  170.305(b) 
and section V.M.2 of this document for further discussion).
    Proposed Sec.  170.303 would define ``Submitter'' to mean a person 
(e.g., an individual, partnership, corporation, association, or other 
legal entity) who is responsible for the submission under subpart F, 
even if another person (such as an attorney, agent, or qualified 
expert) prepares or submits the information. This definition would 
parallel the definition of ``Notifier'' for a GRAS notice (see Sec.  
170.203), while also differentiating the people responsible for a GRAS 
notice (``notifiers'') from those who are responsible for this 
information in accordance with proposed Sec.  170.303 (``submitters'').
2. Specific Requirements Proposed for the Option To Submit Information 
To Be Excepted From Mandatory GRAS Notice Submission
    As discussed in section V.F of this document, we are proposing a 
limited number of exceptions to the proposed GRAS notice submission 
requirement. One exception would state that a GRAS notice does not need 
to be submitted if certain information about the conditions of use of a 
substance is submitted to FDA in accordance with proposed Sec.  170.305 
and the submission is included on a public list maintained by FDA, 
unless we issue a determination that a GRAS notice or a food additive 
petition must be submitted for the intended use of a substance (see 
proposed Sec.  170.205(b)(7)). Any person could rely on the inclusion 
of the submission on a public list maintained by FDA for the same 
conditions of use of a substance.
    Proposed Sec.  170.305 would provide a streamlined way for us to 
gain insight into substances already in use in the market under the 
GRAS provision of section 201(s) of the FD&C Act. We are proposing this 
exception because we recognize that many persons have relied on section 
201(s) of the FD&C Act and our existing regulations to market uses of 
substances based on an independent conclusion of GRAS status. Requiring 
GRAS notices for all such uses of substances would likely overburden 
the administrative resources we have to evaluate and respond to GRAS 
notices. This exception will enable us to administer the proposed 
mandatory GRAS notification program more effectively and efficiently.
    Proposed Sec.  170.305(a) would describe the substances that could 
be the subject of these streamlined submissions, i.e., substances that 
have been introduced into interstate commerce before the effective date 
of any final rule resulting from this rulemaking based on a conclusion 
that the substance is GRAS

[[Page 51856]]

under the conditions of its intended use. Proposed Sec.  170.305(a) 
would state that, for a substance that has been introduced into 
interstate commerce before the effective date of any final rule under 
the GRAS provision of section 201(s) of the FD&C Act, a person may 
submit information regarding the substance and its conditions of use in 
accordance with subpart F instead of submitting a GRAS notice under 
proposed Sec.  170.205. Obtaining this information for substances 
already in use in food would better inform our oversight of the food 
supply and help us prioritize our post-market review of substances used 
in food.
    Proposed Sec.  170.305(b) would not allow a submission under this 
subpart in two circumstances, even if a substance would otherwise 
qualify under Sec.  170.305(a). First, a submission would not be 
allowed under this subpart if the submission concerned any conditions 
of use of a substance that are the subject of an insufficient basis 
letter (proposed Sec.  170.305(b)(1)). If the conditions of use of a 
substance are the subject of an insufficient basis letter, this means 
that we have evaluated the data and information in a prior GRAS notice 
for the substance under the conditions of its intended use and 
determined that the GRAS notice does not provide a sufficient basis for 
a conclusion that the notified substance is GRAS under the conditions 
of intended use. Under these circumstances, a new GRAS notice would 
have to be submitted that covers the substance purported to be GRAS 
under the conditions of its intended use to enable us to re-evaluate 
whether data and information provides a sufficient basis for a GRAS 
conclusion (and whether the insufficient basis should be revised or 
rescinded), or whether the use of the substance should be the subject 
of a food additive petition.
    Second, a submission would not be allowed under this subpart if the 
submission concerned any conditions of use of a substance that are the 
subject of a determination by FDA that the substance is not GRAS under 
the conditions of its intended use (proposed Sec.  170.305(b)(2)). If 
the conditions of use of a substance are the subject of such a 
determination by FDA, this means we have evaluated data and information 
relating to a substance and determined that such conditions of use of a 
substance are not GRAS. As explained in section III.B.1.a of this 
document, we post our determinations that the conditions of use of a 
substance are not GRAS on a public inventory (see Ref. 20). Under these 
circumstances, we would expect to receive a food additive petition for 
the substance's conditions of use. However, if a person believes that 
there are data or information supporting the conclusion that the 
substance is GRAS under these conditions of use, we would require the 
submission of a GRAS notice so that we can adequately evaluate that 
GRAS conclusion.
    Proposed Sec.  170.305(c) would detail what a submission must 
include (proposed Sec.  170.305(c)(1)), additional information that it 
may include (proposed Sec.  170.305(c)(2)), and how the submission must 
be made and by when (proposed Sec.  170.305(c)(3)).
    Proposed Sec.  170.305(c)(1)(i) would require the submission to 
include the name and address of the submitter. This is necessary for 
full identification of the person who accepts responsibility for the 
submission. This is also necessary so that we can ask a submitter 
questions about their submission (proposed Sec.  170.305(d)(2)). 
Proposed Sec.  170.305(c)(1)(ii) would require the submission to 
include the name of the substance, using an appropriately descriptive 
term. This is necessary to identify the substance to both FDA and the 
public. Proposed Sec.  170.305(c)(1)(iii) would require the submission 
to include the conditions of intended use of the substance, including 
the foods in which the substance is used or is in contact with, the 
levels of use, and the purposes for which the substance is used. 
Information describing the conditions of intended use is necessary to 
delineate the boundaries of the submission under this subpart and the 
GRAS provision of section 201(s) of the FD&C Act. The information that 
would be required to be submitted under proposed Sec.  170.305(c)(1)(i) 
through (iii) aligns with information submitted as part of a GRAS 
notice (see Sec.  170.225(c)(2) through (4)). We are not proposing to 
require that submissions under proposed subpart F include underlying 
data or information pertaining to a conclusion of GRAS status.
    Proposed Sec.  170.305(c)(1)(iv) would require the submission to 
include evidence of presence of the substance under the conditions of 
its intended use in interstate commerce before the effective date of 
any final rule resulting from this rulemaking. Evidence of presence in 
interstate commerce before the effective date of any final rule 
resulting from this rulemaking would be necessary, as only those 
substances that have been introduced into interstate commerce before 
this time can take advantage of the option to submit under proposed 
subpart F of part 170. We would offer this alternative to submitting a 
GRAS notice only for substances already in interstate commerce under 
the GRAS provision of section 201(s) of the FD&C Act so that we can 
gather information on all purported GRAS uses of substances and not 
just for new uses moving forward. Uses of substances that are excepted 
from the definition of a food additive under section 201(s)(1) through 
(6) of the FD&C Act cannot be the subject of a GRAS notice. Likewise, 
uses of substances that are excepted from the definition of a food 
additive under section 201(s)(1) through (6) of the FD&C Act would be 
ineligible for this alternative to submitting a GRAS notice for uses of 
substances already in interstate commerce. As this option is available 
as an exception to the proposed requirement to submit a GRAS notice, it 
would be available only for uses of substances that can properly be the 
subject of a GRAS notice.
    Proposed Sec.  170.305(c)(1)(v) would require the submitter to 
include a GRAS notice file number (GRN No.) if FDA sent a cease to 
evaluate letter in response to a submitter's previous GRAS notice for 
the same conditions of intended use of a substance. Information about a 
submitter's previous GRAS notice in the form of submitting to us the 
GRN No. is necessary, as safety issues raised during our evaluation of 
a GRAS notice that we ceased to evaluate may warrant consideration as a 
higher priority.
    Proposed Sec.  170.305(c)(2) would provide that a submission may 
inform us of the statutory basis for the conclusion of GRAS status for 
the conditions of intended use of the substance (i.e., through 
scientific procedures or through experience based on common use in food 
(section 201(s) of the FD&C Act; see also Sec.  170.30(a) through 
(c))), but this information would not be a required element of the 
submission. This information is not necessary to establish the presence 
of a substance already in interstate commerce under the GRAS provision 
of section 201(s) of the FD&C Act, but we recommend its inclusion 
because it would help us understand the basis for the GRAS conclusion.
    Proposed Sec.  170.305(c)(3) would require that a submission under 
this section be submitted to us electronically through COSM within one 
year after the effective date of any final rule, unless provided with a 
waiver to submit on paper. This would align with our proposed 
requirement for electronic submission of GRAS notices (see proposed 
Sec.  170.210). The proposed one-year deadline to make these 
submissions would enable us to obtain information on many substances 
already

[[Page 51857]]

in use in food, informing our oversight of the food supply and helping 
us prioritize our post-market review of these substances. The one-year 
deadline would also allow many affected parties to efficiently comply 
with new proposed regulatory requirements, while helping us to more 
effectively administer the proposed mandatory GRAS notification 
program.
    Proposed Sec.  170.305(c)(3) would provide that submissions under 
subpart F of part 170 will not be accepted beyond one year after the 
effective date of any final rule resulting from this rulemaking. This 
would provide a clear cutoff for submissions under this subpart.
    Proposed Sec.  170.305(d) would outline what we will do with these 
submissions. Proposed Sec.  170.305(d)(1) would state that we will post 
the information we receive (i.e., information listed in proposed Sec.  
170.305(c)(1) and (2)) in a publicly available list in accordance with 
part 20 and clarify that the posting of this information does not mean 
that we have reviewed the GRAS status of the substance's conditions of 
intended use. This would provide transparency into the substances that 
are purported to be GRAS under the conditions of their intended use, 
and it would enable us to develop a more comprehensive catalog of food 
substances in use in the market under the GRAS provision of section 
201(s) of the FD&C Act.
    Proposed Sec.  170.305(d)(2) would enable us to ask a submitter 
questions about their submission. This is necessary for us to ask 
clarifying questions about any information provided or to help us 
determine whether we need more information about the use of a 
substance.
    Proposed Sec.  170.305(d)(3) would state that we may issue a 
determination that a GRAS notice or food additive petition must be 
submitted for the intended use of a substance in accordance with 
subpart E of part 170 or section 409 of the FD&C Act, respectively. 
This would mean that the conditions of use of the substance would not 
qualify for the exception from the GRAS notice submission requirement 
under proposed Sec.  170.205(b)(7). The submitter would have to submit 
a GRAS notice in accordance with subpart E of part 170 or, under 
certain circumstances, a food additive petition in accordance with 
section 409 of the FD&C Act. Proposed Sec.  170.305(d)(3) would also 
state that we would make such a determination publicly available. This 
would provide transparency into the substances that were purported to 
be GRAS under the conditions of their intended use but no longer 
qualify for the exception from the GRAS notice submission requirement 
under proposed Sec.  170.205(b)(7).
    While we are not proposing to require that submissions under 
proposed subpart F include underlying data or information pertaining to 
a conclusion of GRAS status, FDA is proposing that we may issue a 
determination that a GRAS notice must be submitted for the intended use 
of a substance that is the subject of a proposed subpart F submission. 
Thus, proposed subpart F would provide a streamlined way for us to gain 
insight into substances already in use in the market under the GRAS 
provision of section 201(s) of the FD&C Act, while still enabling us to 
require that additional information (in the form of a GRAS notice) be 
submitted for certain uses of these substances.

N. Proposed Revision to the Header of Part 170

    Part 170 of Title 21 is titled ``Part 170--Food Additives;'' 
however, it not only covers food additives but also our GRAS 
regulations. Therefore, to reflect the subject matter of this part more 
accurately, we propose renaming part 170 to ``Part 170--Food Additives 
and Generally Recognized as Safe (GRAS) Substances.''

O. Non-Substantive Edits to Part 170

    We propose several non-substantive edits throughout part 170 to 
align with federal plain language guidelines (Ref. 42). We propose 
revising ``prior to'' to ``before''; ``shall'' to ``must,'' ``will,'' 
or ``are''; ``assist'' to ``help''; and ``agency'' to ``FDA'' (see 
proposed Sec. Sec.  170.30(c)(2), (d), (e), (i)(1), 170.38(b)(1) and 
(b)(2), and 170.39(b), (c), (d), (e), and (f)).
    We propose other non-substantive edits to update terms and improve 
clarity. We propose changing ``company'' to ``requestor,'' ``part 182, 
part 184, or part 186 of this chapter'' to ``parts 182, 184, or 186 of 
this chapter,'' and ``Federal Food, Drug, and Cosmetic Act'' to ``the 
Act'' (as defined in Sec.  170.3(d) for use throughout part 170) (see 
proposed Sec. Sec.  170.30(c)(2) and (d), 170.38(b)(3), 170.39(e), 
170.203, and 170.225(c)(6)). We propose changing ``Commissioner'' and 
``he'' or ``his'' to ``FDA'' and ``its,'' respectively, adding ``of 
this chapter'' after ``Sec.  171.130(b),'' and adding ``under the 
conditions of its intended use'' after ``substance is GRAS'' (see 
proposed Sec.  170.38(a), (b)(1), and (b)(3)).
    Proposed Sec. Sec.  170.203 and 170.225(c)(6) would clarify that 
``premarket approval requirements of the Federal Food, Drug, and 
Cosmetic Act'' means ``premarket review and approval requirements for 
food additives under section 409 of the Act.'' As defined in Sec.  
170.3(d), ``the Act'' means the FD&C Act and as discussed in the prior 
paragraph, we propose using this term throughout part 170 consistent 
with this definition. In creating the premarket approval requirement 
for food additives in the 1958 amendment, Congress excluded a substance 
that is GRAS under the conditions of its intended use from the 
definition of food additive. The creation of the GRAS provision 
reflected Congress' determination that many substances intentionally 
added to food for a specific use do not need premarket review by FDA to 
ensure their safety, either because their safety has been established 
by a long history of use in food, or because their safety has been 
established by information that is generally available to and accepted 
by qualified experts, regarding the intended conditions of use of a 
substance in food. This revision would help avoid any confusion with 
the mandatory GRAS notification submission and with other premarket 
submissions (e.g., new dietary ingredient notifications).

P. Table Summarizing the Proposed Changes to Part 170

    In table 1, we briefly summarize the proposed changes to part 170 
and how they would impact the existing GRAS regulations at part 170. 
Table 1 provides the current section citation in part 170, the 
corresponding proposed section citation in part 170, and a summary of 
the proposed revision which includes a cross-reference to the section 
of this document that discusses the reasons for the proposed revision.

Q. Proposed Revisions to Part 570 for Food Substances Used in Animal 
Food and Incorporation by Reference

    FDA is also proposing to amend certain provisions of part 570. The 
proposed revisions to the animal food regulations in part 570 largely 
track the proposed revisions to the human food regulations in part 170 
because parts 170 and 570 implement the same statutory provisions, and 
the rationale for proposing these revisions is the same. However, there 
are some proposed revisions to part 570 that are different from the 
proposed revisions to their counterpart regulation in part 170, some 
proposed revisions to part 570 that have no counterpart in part 170, 
and some proposed revisions to part 170 that have no counterpart in 
part 570.
1. Proposed Revisions to Part 570 That Parallel the Proposed Revisions 
to Part 170
    See table 2 for a summary of the proposed revisions to part 570 
that are parallel to the proposed revisions to part 170. Table 2 
provides the proposed revision section in part 570, the parallel 
proposed revision section in part 170, and a summary of the proposed 
revision which includes a cross-reference to the section of this 
document that discusses the reasons for the proposed revision.

BILLING CODE 4164-01-C
    Related to proposed Sec.  570.205(b)(1), we are seeking comment on 
our tentative conclusion that, in light of existing regulations 
providing for the incorporation of data and information previously 
submitted to FDA into a new GRAS notice (see 21 CFR 570.215), it is 
unnecessary to provide for an alternate procedure (e.g., abbreviated 
animal food GRAS notice submission) for substances that exist in our 
animal food GRAS notice inventory. For example, this would involve 
situations where the use of an animal food substance differs from the 
uses discussed in an existing animal food GRAS notice that received a 
no questions letter or when there is a change in manufacturing process 
related to the uses of an animal food substance discussed in an 
existing animal food GRAS notice that received a no questions letter. 
We also invite comment on additional ways in which we could facilitate 
or make more efficient a notifier's ability to incorporate data and 
information already submitted to FDA into a new animal food GRAS 
notice, as well as on other specific animal food scenarios for which 
FDA could consider providing an alternate procedure (e.g., abbreviated 
GRAS notice submission) or that FDA could consider to be covered by an 
existing no questions letter. Refer to section V.F.2 of this document 
for additional discussion of this tentative conclusion and these 
requests for comment.
    Our regulations, at Sec.  570.38(d), provide that if we are aware 
of a prior sanction for use of a substance, FDA will concurrently 
propose a separate regulation for such use. This proposed rule would 
remove Sec.  507.38(d). Prior sanctioned uses of substances for human 
food use are almost all for use in manufacturing food packaging 
materials (see 21 CFR part 181, subpart B). The prior sanctioned 
substances for human food use were placed in the then-new part 181 in 
1977 (42 FR 14302, 14638-40, March 15, 1977). At the same time, FDA 
amended part 570 to include Sec.  570.13, which incorporates the 
regulations in part 181 for use in the manufacture of animal food-
packaging materials (42 FR 14091, March 15, 1977). Since then, the only 
prior sanctioned uses of a substance for animal food that we are aware 
of are menadione and menadione sodium bisulfite complex (certain 
vitamin K active substances) for use in poultry feed (48 FR 16748, 
April 19, 1983). A person wishing to assert that an animal food use of 
a substance is prior sanctioned should contact CVM at [email protected] to discuss their situation.
2. Proposed Revisions to Part 570 That Are Different From Parallel 
Proposed Revisions to Part 170
    The proposed changes to parts 170 and 570 also differ slightly 
regarding the administration of the mandatory GRAS notification 
program. Where proposed Sec.  170.205(a) would reference FCNs as an 
alternate pathway for conditions of use of a substance that meet the 
definition of an FCS in accordance with Sec.  170.3(e)(3), proposed 
Sec.  570.205(a) would not include this language because the FCN 
program is specific to human foods.
    Our regulations, at Sec.  570.210, specify where a GRAS notice is 
to be submitted. Proposed Sec.  570.210 would be revised to include a 
technical change to replace ``Division of Animal Feeds (HFV-220)'' with 
``Division of Animal Food Ingredients'' to bring our regulations up to 
date with FDA's current structure. The proposed changes would also 
instruct notifiers to contact CVM's Division of Animal Food Ingredients 
by email prior to submitting a GRAS notice for the most current 
instructions on submission, while we consolidate our physical location, 
including our mailing address, and transition from paper submissions to 
online submissions. If the proposed rule is finalized, we also 
anticipate making additional information on how to submit an animal 
food GRAS notice available on our website.
    In proposed subpart F of part 570, in which we would provide 
definitions that would apply only to this subpart (see proposed Sec.  
570.303) and describe the time-limited option that firms can choose to 
participate in to qualify for an exception to the GRAS notice 
submission requirement (see Sec.  507.305), the definitions and 
requirements are identical to those applicable to human food under 
proposed subpart F of part 170, with the exception of proposed Sec.  
570.305(c)(1)(iii) and (iv).
    Proposed Sec.  570.305(c)(1)(iii) would specify that submissions 
must include: the intended conditions of use of the substance, 
including the target animal species; foods in which the substance is 
used; the levels of use in such foods; the purposes for which the 
substance is used; and, when the intended use is in food for food-
producing animals, the quantities of any residues that humans may be 
exposed to in edible animal tissues. Therefore, we propose limiting 
these submissions, when applicable, to substances for which the 
submitter had data or information to support human food safety related 
to such use.
    Proposed Sec.  570.305(c)(1)(iv) would require that the submission 
include evidence of presence of the substance under the conditions of 
its intended use

[[Page 51866]]

in interstate commerce before the effective date of any final rule 
resulting from this rulemaking. The conditions of intended use include, 
when applicable, being marketed for a particular target animal species 
and use.
    Proposed Sec.  570.305(c)(3) would detail how the submission must 
be made and by when. We propose that a submission under this section 
must be submitted to CVM by email within one year after the effective 
date of any final rule.
3. Proposed Revisions to Part 570 That Have No Counterpart in Part 170
    We are proposing an exception in Sec.  570.205(b)(5) from the 
requirement to submit a GRAS notice if the intended use of the 
substance has been the subject of an established animal food ingredient 
consultation process with FDA and a summary document made publicly 
available by FDA through the consultation process indicates that FDA 
has no questions or concerns about the safety of the substance for the 
intended use.
    An example of such a consultation process is the Animal Food 
Ingredient Consultation (AFIC), described in our Guidance for Industry 
(GFI) #294 (Ref. 43). This guidance describes an interim, voluntary 
process that helps FDA become aware of some new animal food ingredients 
that are marketed in interstate commerce and any potential safety 
concerns associated with them. Upon completion of a consultation under 
AFIC, FDA intends to provide a letter summarizing the information that 
FDA reviewed in order to conclude whether the agency has questions 
about the safe use of the ingredient, and to post the letter to an FDA 
web page. The consultation provides FDA with the opportunity to express 
our concerns to a person regarding their plan to market an animal food 
ingredient without further evaluation through a GRAS notice or an 
animal food additive petition when we have questions about the public 
health impact. Because AFIC enables FDA to examine intended uses of 
substances in animal food, we propose that a GRAS notice would not be 
required for anyone marketing a substance for a particular use that was 
reviewed by FDA under AFIC, so long as FDA provided a publicly 
available summary that indicates it has no questions or concerns about 
the safety of the substance for the intended use.
    In addition, for animal food ingredients that are listed in and 
used in accordance with Chapter 6 ``Official Feed Terms, Common or 
Usual Ingredient Names and Ingredient Definitions'' of the ``Official 
Publication'' (OP) of the Association of American Feed Control 
Officials, Inc. (AAFCO), 2024 ed., (Ref. 44) and for which FDA has not 
publicly expressed a concern about the GRAS status of the use of the 
ingredient, we provide an exception in proposed Sec.  570.205(b)(6) 
from the requirement to submit a GRAS notice. This exception would be 
applicable if the ingredient is introduced in interstate commerce for 
use in animal food under the GRAS provision of section 201(s) of the 
FD&C Act and may overlap with other exceptions (e.g., inclusion in part 
582, coverage by a GRAS notification that has received a no questions 
letter from FDA).
    We are proposing to except these ingredients from the requirement 
to submit a GRAS notice because we are aware of their use given their 
listing in AAFCO's 2024 OP, and we have reviewed many of them for 
safety for their intended use in animal food through our former 
participation in the AAFCO ingredient definition request process under 
a memorandum of understanding (MOU) that expired in October 2024 (Ref. 
45). Moreover, for ingredients that were reviewed as part of the AAFCO 
ingredient definition request process but that we did not specifically 
review as part of the MOU process, we are not aware of any safety 
issues concerning them and many have a long history of use in animal 
food. For animal food ingredients listed and used in accordance with 
editions of the AAFCO OP other than the 2024 edition, and for animal 
food ingredients that are used in accordance with the AAFCO 2024 OP but 
that are the subject of a public FDA statement of concern regarding 
their GRAS status, the exception in Sec.  570.205(b)(6) would not 
apply, and proposed Sec.  570.205(a) would require a GRAS notice if the 
substance is being introduced into interstate commerce under the GRAS 
provision of section 201(s) of the FD&C Act.
    Proposed Sec.  570.205(b)(5) and proposed Sec.  570.205(b)(6) have 
therefore been added to structure a mandatory GRAS notification program 
for animal food ingredients that takes into account the unique 
circumstances of how animal food has historically been regulated by 
States and FDA, as well as how we anticipate we will continue to 
regulate animal food ingredients.
4. Proposed Revisions to Part 170 That Have No Counterpart in Part 570
    Proposed Sec.  170.39 would expand the scope of the TOR exemption 
to include uses in human food and FCSs generally, not just food contact 
articles. There is no TOR exemption for animal food, and we do not 
propose one at this time because we are unaware that there is a need 
for such a regulation for animal food and because of the complexities 
involved in determining appropriate TOR criteria for animal species 
with differing body sizes, diets, feeding practices, and physiologies. 
As there is no TOR provision or FCN program for animal food, the 
exceptions we are proposing in Sec.  170.205(b)(5) and (b)(6) would not 
apply to animal food GRAS notices. The changes we are proposing to 
Sec.  570.205(b) would therefore not contain these two exceptions.
5. Incorporation by Reference
    In Sec.  570.205(b)(6), FDA is proposing to incorporate by 
reference the ``Official Common or Usual Names and Definitions of Food 
Ingredients'' section of Chapter 6 of the ``Official Publication'' of 
AAFCO, 2024 edition, pages 367-549.
    You may obtain a free copy of the material from the Docket for GFI 
#293, FDA Enforcement Policy for AAFCO-Defined Animal Feed Ingredients, 
at https://www.regulations.gov/document/FDA-2024-D-2977-0003 or you may 
inspect a copy at the Dockets Management Staff (HFA-306), Food and Drug 
Administration, 5630 Fishers Lane, Rm. 1061, Rockville MD 20852; phone 
240-402-7500, between 9 a.m. and 4 p.m., Monday through Friday. You may 
also purchase a copy from AAFCO, 1800 S Oak Street, Suite 100, 
Champaign, IL, 61820-6974; phone: 217-356-4221; website (including 
links for purchasing AAFCO publications): https://www.aafco.org.
    Chapter 6 of the 2024 edition of the ``Official Publication'' 
contains a comprehensive list of animal food ingredients, many of which 
include definitions established through AAFCO's ingredient definition 
request process. Because most States adopt the ingredient definitions 
listed in the ``Official Publication'' under their State laws, the 
publication facilitates the marketing of animal food ingredients under 
those State laws. As explained above, for animal food ingredients that 
are listed in and used in accordance with Chapter 6 of the 2024 edition 
of AAFCO's ``Official Publication,'' we are proposing an exception in 
proposed Sec.  570.205(b)(6) from the requirement to submit a GRAS 
notice, as long as FDA has not publicly expressed a concern about the 
GRAS status of the use of the ingredient.
    We are proposing to incorporate by reference the ``Official Common 
or Usual Names and Definitions of Feed Ingredients'' section of Chapter 
6 of the 2024 edition of AAFCO's ``Official Publication,'' pages 367-
549, for the

[[Page 51867]]

sole purpose of providing a list of ingredients that would be covered 
by proposed Sec.  570.205(b)(6).

VI. Request for Comments on Alternatives

    In addition to seeking comments on the overall proposed rule, FDA 
is specifically seeking comments on potential alternatives to the 
proposed rule that could reduce regulatory burdens (e.g., allowing 
streamlined submissions for all substances purported to be GRAS under 
the conditions of their intended use under section 201(s) of the FD&C 
Act). FDA is seeking comments on any alternatives that would still meet 
our goals of helping FDA fulfill its statutory responsibility to 
prohibit the use of unsafe additives in food and of increasing 
transparency about the substances being added to the U.S. food supply. 
In addition, FDA is interested in comments on whether such alternatives 
would enhance our ability to protect public health by helping FDA 
identify the use of potentially unsafe substances in food or additives 
that require FDA review and approval to be lawfully marketed, so we can 
take action as appropriate. FDA is seeking data and other information 
to support any suggested alternatives, including how such an 
alternative would meet FDA's goals of protecting public health and 
increasing transparency.

VII. Proposed Effective/Compliance Dates

    We intend that any final rule resulting from this rulemaking become 
effective 60 days after the date of the final rule's publication in the 
Federal Register.
    We also propose that Sec. Sec.  170.205 and 570.205, if finalized, 
have a compliance date of 18 months after the effective date of the 
final rule. Based on our experience reviewing GRAS notices under the 
voluntary GRAS notification program, we think that a compliance period 
of 18 months would provide industry with sufficient time to come into 
compliance with these proposed requirements and for FDA to make 
available on a public list the information that is submitted under the 
time-limited option to make a streamlined submission to FDA for certain 
substances already in interstate commerce in proposed Subpart F that 
has a period of one year from the effective date. The availability of 
this information on a public list would be necessary to inform industry 
whether the exception in proposed Sec. Sec.  170.205(b)(7) and 
570.205(b)(7) applies.

VIII. Preliminary Economic Analysis of Impacts

    We have examined the impacts of the proposed rule under Executive 
Order 12866, Executive Order 13563, Executive Order 14192, the 
Regulatory Flexibility Act (5 U.S.C. 601-612), and the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4).
    Executive Orders 12866 and 13563 direct us to assess all benefits 
and costs of available regulatory alternatives and, when regulation is 
necessary, to select regulatory approaches that maximize net benefits. 
Rules are economically significant under Executive Order 12866 if they 
have an annual effect on the economy of $100 million or more; or 
adversely affect in a material way the economy, a sector of the 
economy, productivity, competition, jobs, the environment, public 
health or safety, or State, local, or tribal governments or 
communities. The Office of Information and Regulatory Affairs (OIRA) 
has determined that this proposed rule is an economically significant 
regulatory action under section 3(f)(1) of Executive Order 12866.
    Executive Order 14192 requires that any new incremental costs 
associated with certain significant regulatory actions ``shall, to the 
extent permitted by law, be offset by the elimination of existing costs 
associated with at least 10 prior regulations.'' This proposed rule, if 
finalized as proposed, is expected to be an Executive Order 14192 
regulatory action.
    The Regulatory Flexibility Act requires us to analyze regulatory 
options that would minimize any significant impact of a rule on small 
entities. Because we estimate that the economic impact of this proposed 
rule is more than 3 percent of annual revenue for small entities, we 
find that the proposed rule would have a significant economic impact on 
a substantial number of small entities.
    The Unfunded Mandates Reform Act of 1995 (Section 202(a)) requires 
us to prepare a written statement, which includes estimates of 
anticipated impacts, before proposing ``any rule that includes any 
Federal mandate that may result in the expenditure by State, local, and 
tribal governments, in the aggregate, or by the private sector, of 
$100,000,000 or more (adjusted annually for inflation) in any one 
year.'' The current threshold after adjustment for inflation is $193 
million, using the most current (2025) Implicit Price Deflator for the 
Gross Domestic Product. This proposed rule would result in an 
expenditure in at least one year that meets or exceeds this amount.
    The primary benefits of the proposed rule, if finalized, would come 
from increased information being made available to FDA and the public 
regarding substances used in human and animal foods. A mandatory GRAS 
notification program would allow FDA to ensure that GRAS conclusions 
have a scientific basis and that appropriate documentation supporting 
those conclusions exists. The proposed rule, if finalized, is in part 
intended to help strengthen public confidence in FDA's ability to 
oversee the safety of the U.S. food supply.
    One-time costs of the proposed rule to persons who introduce a 
substance into interstate commerce under the GRAS provision of section 
201(s) of the FD&C Act include reading the rule and revising standard 
operating procedures regarding GRAS notices. Other one-time costs of 
the proposed rule are preparing and submitting streamlined submissions 
related to uses of substances introduced into interstate commerce under 
the GRAS provision of section 201(s) of the FD&C Act before the 
effective date of a final rule, for firms that choose to submit this 
information during the window of availability for this time-limited 
option for such submissions. Costs associated with these activities may 
include translation costs for manufacturers in non-English speaking 
countries. Recurring costs to affected manufacturers include preparing 
and submitting GRAS notices for new uses of substances introduced into 
interstate commerce under the GRAS provision of section 201(s) of the 
FD&C Act after the effective date of a final rule that would otherwise 
have been the subject of an independent conclusion of GRAS status.
    Costs to FDA would include one-time costs of reviewing streamlined 
submissions related to uses of substances introduced into interstate 
commerce under the GRAS provision of section 201(s) of the FD&C Act 
before the effective date of a final rule during the time-limited 
period for such submissions and annual costs of evaluating ongoing 
submissions of GRAS notices regarding uses of substances that would 
otherwise have been the subject of an independent conclusion of GRAS 
status.
    We estimate that the present value of the costs of the proposed 
rule would be approximately $89.6 million, with a lower bound of $34.9 
million and an upper bound of $210.0 million, discounted at 3 percent 
at 10 years in 2024 dollars. At a 7 percent discount rate, the present 
value of costs would be approximately $82.3 million, with a lower bound 
of $31.5 million and an upper bound of $195.9 million. We

[[Page 51868]]

estimate that the annualized costs of the proposed rule would be 
approximately $10.5 million, with a lower bound of $4.1 million and an 
upper bound of $24.6 million, discounted at 3 percent over 10 years. At 
a 7 percent discount rate, annualized costs would be approximately 
$11.7 million, with a lower bound of $4.5 million and an upper bound of 
$27.9 million. The estimated benefits and costs of the proposed rule 
are summarized in table 3.
[GRAPHIC] [TIFF OMITTED] TP11AU26.051

    In line with Executive Order 14192, we estimate present and 
annualized values of costs, cost savings, and net costs over an 
infinite time horizon in table 4. The net present value of the costs of 
the proposed rule are approximately $86.0 million, with a lower bound 
of $37.8 million and an upper bound of $189.7 million, discounted at 7 
percent over an infinite time horizon in 2024 dollars. The annualized 
costs of the proposed rule are approximately $6.0 million, with a lower 
bound of $2.6 million with an upper bound of $13.3 million.
[GRAPHIC] [TIFF OMITTED] TP11AU26.052

    We have developed a Preliminary Economic Analysis of Impacts that 
assesses the impacts of the proposed rule. The full preliminary 
analysis of economic impacts is available in the docket for this 
proposed rule (Ref. 46) and at https://www.fda.gov/economics-staff/regulatory-impact-analyses-ria.

IX. Analysis of Environmental Impact

    We have determined under 21 CFR 25.30(h) that this action is of a 
type that does not individually or cumulatively have a significant 
effect on the human environment. Therefore, neither an environmental 
assessment nor an environmental impact statement is required.

[[Page 51869]]

X. Paperwork Reduction Act of 1995

    This proposed rule contains information collection provisions that 
are subject to review by OMB under the Paperwork Reduction Act of 1995 
(44 U.S.C. 3501-3521). A description of these provisions is given in 
the Description section below with an estimate of the annual reporting. 
Included in the estimate is the time for reviewing instructions, 
searching existing data sources, gathering, and maintaining the data 
needed, and completing and reviewing each collection of information.
    FDA invites comments on these topics: (1) whether the proposed 
collection of information is necessary for the proper performance of 
FDA's functions, including whether the information will have practical 
utility; (2) the accuracy of FDA's estimate of the burden of the 
proposed collection of information, including the validity of the 
methodology and assumptions used; (3) ways to enhance the quality, 
utility, and clarity of the information to be collected; and (4) ways 
to minimize the burden of the collection of information on respondents, 
including through the use of automated collection techniques, when 
appropriate, and other forms of information technology.
    Title: Substances Generally Recognized as Safe: Notification 
Procedure; OMB Control Number 0910-0342--Revision.
    Description: The FD&C Act requires that all food additives (as 
defined by section 201(s) of the FD&C Act) be reviewed and approved by 
FDA before they are marketed. Section 409 of the FD&C Act establishes a 
premarket review and approval requirement for ``food additives.'' 
Section 201(s) of the FD&C Act provides an exclusion to the definition 
of food additive, and thus from the food additive premarket review and 
approval requirement, for uses of substances that are GRAS by qualified 
experts. The GRAS provision of section 201(s) of the FD&C Act is 
implemented in parts 170 and 570 for human food and animal food, 
respectively. The provisions include an administrative procedure for a 
person to voluntarily notify FDA about a conclusion that a substance is 
GRAS under the conditions of its intended use in food for humans or 
animals.
    A GRAS notice will include the following information:
     signed statements and a certification;
     the identity, method of manufacture, specifications, and 
physical or technical effect of the notified substance;
     dietary exposure to the notified substance (and human 
exposures when used in food for food-producing animals);
     self-limiting levels of use in circumstances where the 
amount of the notified substance that can be added to human food or 
animal food is limited because the food containing levels of the 
notified substance above a particular level would become unpalatable or 
technologically impractical;
     evidence of substantial history of consumption of the 
substance for food use by a significant number of consumers (or animals 
in the case of animal food) prior to January 1, 1958, if a conclusion 
of GRAS status is based on common use of the substance in food prior to 
1958;
     a narrative that provides the basis for the notifier's 
conclusion of GRAS status, including why the data, information, 
methods, and principles described in the notice provide a basis for the 
conclusion that the notified substance is generally recognized, among 
qualified experts, to be safe under the conditions of its intended use; 
and
     a list of the data and information the notifier cites in 
the GRAS notice.
    This proposed rule, if finalized, would amend our regulations in 
parts 170 and 570 to require the submission of GRAS notices for the use 
of a human or animal food substance that is purported to be GRAS under 
the conditions of its intended use under section 201(s) of the FD&C 
Act. This proposed rule would require any person introducing a 
substance into interstate commerce under the GRAS provision of section 
201(s) of the FD&C Act to notify FDA of the basis for their conclusion 
that the substance is GRAS under the conditions of its intended use 
unless an exception to the requirement to submit a GRAS notice applies. 
In short, the proposed rule would convert the voluntary GRAS 
notification program to a mandatory GRAS notification program. This 
change would provide greater transparency about substances that are 
added to food (including substances already in the food supply and 
those being introduced into interstate commerce for use in food for the 
first time) so that FDA can more efficiently determine if the use of a 
substance constitutes a food additive use that is subject to the 
premarket review and approval requirements of the FD&C Act. This will 
therefore enable FDA to more effectively regulate the safety of food 
substances and ultimately help identify the use of potentially unsafe 
substances in food, so we can take action as appropriate.
    The proposed rule would establish certain exceptions to the 
requirement to submit a GRAS notice, including a time-limited option to 
make a streamlined submission to FDA for certain substances already in 
interstate commerce under the GRAS provision of the FD&C Act instead of 
initially submitting a GRAS notice. The submission must include: (1) 
the name and address of the submitter; (2) the name of the substance, 
using an appropriately descriptive term; (3) the intended conditions of 
use of the substance, including the foods in which the substance is 
used or is in contact with, the levels of use, and the purposes for 
which the substance is used (and the target animal species for animal 
food as well as human exposures when used in food for food-producing 
animals); (4) evidence of presence in interstate commerce before the 
effective date of the final rule; and (5) if applicable, where FDA sent 
a cease to evaluate letter in response to a notifier's previous GRAS 
notice (GRN or AGRN), provide that file number (GRN No. or AGRN No.) as 
part of the submission.
    The proposed rule would revise our procedural regulations for a TOR 
exemption for human food to reflect updated scientific guidance and to 
include substances used in food and as an FCS. FDA has an existing 
information collection for information submitted in support of a TOR 
exemption for a food contact substance under OMB control number 0910-
0495 (Food Additives; Food Contact Substances Notification System). The 
proposed rule would allow manufacturers and suppliers to also seek the 
TOR exemption for substances used in food. A request for a TOR 
exemption will include: (1) the chemical composition of the substance 
for which the request is made; (2) detailed information on the 
conditions of use of the substance; (3) a clear statement of the basis 
for the request for exemption from regulation as a food additive; (4) 
data that will enable FDA to estimate the daily dietary concentration 
resulting from the proposed use of the substance; (5) results of a 
literature search for toxicological data on the substance and its 
impurities; and (6) information on the environmental impact that would 
result from the proposed use.
    HFP would require notifiers or submitters to submit data 
electronically using the Centralized Online Submission Module (COSM) 
(Form FDA 3667) (https://www.fda.gov/food/registration-food-facilities-and-other-submissions/centralized-online-submission-module-cosm) for 
GRAS

[[Page 51870]]

notices, the time-limited option to submit information for certain 
substances already in interstate commerce, and requests for a TOR 
exemption. Notifiers may request a waiver from HFP to submit on paper 
at Office of Pre-Market Additive Safety, Human Foods Program, Food and 
Drug Administration, 5001 Campus Dr., College Park, MD 20740. CVM would 
require notifiers to contact CVM by email at [email protected] before submitting a GRAS notice. For the time-
limited option to submit information for certain substances already in 
interstate commerce, CVM would require submitters to send data by email 
at [email protected].
    Description of Respondents: Respondents to the collection of 
information are manufacturers of substances used in food for humans and 
animals.
    We estimate the burden of this collection of information as 
follows:
[GRAPHIC] [TIFF OMITTED] TP11AU26.053

    The burden estimates in tables 5 and 6 are consistent with the 
estimates found in the Preliminary Regulatory Impact Analysis (PRIA) 
(Ref. 46). The existing information collection for annual voluntary 
GRAS notices, OMB control number 0910-0342 (Substances Generally 
Recognized as Safe: Notification Procedure), estimates 100 firms for 
human foods and 12 firms for animal food that voluntarily submitted 
GRAS notices for a total of 112 firms. These annual estimates are based 
on our experience with the voluntary GRAS notice program, and we 
include with them our annual estimates for additional firms that will 
submit GRAS notices to comply with the proposed rule, if finalized.
    In table 15 of the PRIA, we estimate that a total of approximately 
98 additional firms, including GRAS substance producers and food 
manufacturers, will submit a GRAS notice annually. Of the new firms, we 
estimate that 94 produce human food, and 4 produce animal food. For 
this analysis, we estimate that 194 firms (100 voluntarily submitting + 
94 due to rulemaking) annually will submit a GRAS notice for human 
food, and 16 firms (12 voluntarily submitting + 4 due to rulemaking) 
will submit a GRAS notice for animal food. In table 14 of the PRIA, we 
estimate that it will take 180 hours to prepare and submit a GRAS 
notice for either human or animal food. Accordingly, we estimate the 
annual burden for submitting a GRAS notice to be 34,920 hours for human 
food (194 notices x 180 hours) and 2,880 hours for animal food (16 
notices x 180 hours).
    We estimate that approximately 58 respondents will request a waiver 
to submit in paper format either a GRAS notice, TOR exemption, or the 
time-limited option to submit information for certain substances 
already in interstate commerce for human food. This annual estimate is 
based on our experience with the voluntary GRAS notice program and the 
annual estimate in the existing information collection approved under 
OMB control number 0910-0342, where we estimate that approximately 30 
percent of submissions are in paper format annually. For this analysis, 
we will assume approximately 30 percent of firms will choose to submit 
in paper format. Thus, 30 percent of the estimated 194 firms for human 
food is about 58 (194 firms x 0.30). We believe respondents will need 
no longer than an hour to prepare such a request as respondents should 
already have any information needed to request a waiver. Accordingly, 
we estimate the annual burden to request a waiver to submit a GRAS 
notice for human food in paper format to be 58 hours.
    The existing information collection for food contact substances 
covers TOR exemption under OMB control number 0910-0495 (Food 
Additives; Food Contact Substances Notification System). For this 
analysis, we will use the same annual estimates for TOR exemption from 
that information collection to apply to the TOR exemption for food 
substances. Thus, we estimate that 7 respondents annually will each 
submit 1 request for a TOR exemption, which will take approximately 48 
hours to prepare and submit. Accordingly, we estimate the annual burden 
to request a TOR exemption for a food substance will be 336 hours (7 
requests x 48 hours).

    In table 7 of the PRIA, we estimate that there are 1,028 unique 
firms with independent conclusions of GRAS status. Based on table 6 of 
the PRIA, we calculate that 94 percent of the independent conclusions 
of GRAS status are for human foods (1,885 human food independent 
conclusions of GRAS status / 2,000 total human and animal independent 
conclusions of GRAS status). We assume the same distribution for the 
number of unique firms preparing a submission for certain substances 
purported to be GRAS based on an independent conclusion of GRAS status. 
Accordingly, we calculate the number of respondents preparing a 
submission for certain substances purported to be GRAS based on an 
independent conclusion of GRAS status for human food to be 966 (1,028 x 
0.94).
    In table 10 of the PRIA, we estimate that each respondent will 
prepare approximately 2.5 submissions for certain substances purported 
to be GRAS based on an independent conclusion of GRAS status that were 
already introduced into interstate commerce before the effective date 
of a final rule. In table 10 of the PRIA, we estimate that there are 
1,740 association expert panel-concluded GRAS substances. As discussed 
in the PRIA, this category includes substances evaluated by the Flavor 
and Extract Manufacturers Association and introduced into interstate 
commerce under section 201(s) of the FD&C Act but can include other 
independent conclusions of GRAS status made by other expert panels 
selected and convened by associations. For efficiency purposes, we 
assume that there will be one submission by one respondent to cover all 
submissions for certain substances purported to be GRAS based on an 
association expert panel GRAS conclusion that were already introduced 
into interstate commerce before the effective date of a final rule.
    Accordingly, we calculate the total number of respondents to be 967 
(966 respondents preparing a submission for certain substances 
purported to be GRAS based on an independent conclusion of GRAS status 
+ 1 respondent preparing a submission for certain substances purported 
to be GRAS based on an association expert panel GRAS conclusion). 
Although we believe that one respondent will have one submission for 
1,740 substances, we estimate that on average each respondent will 
submit 2.5 responses. Thus, we calculate that 2,418 submissions 
(rounded up from 2,417.5) will be submitted for certain substances 
purported to be GRAS based on an association expert panel GRAS 
conclusion that were already introduced into interstate commerce before 
the effective date of a final rule (967 respondents x 2.5 responses).
    In table 10 of the PRIA, we estimate that it will take 
approximately 32 hours (rounded up from 31.5) to prepare a submission 
for certain substances purported to be GRAS under section 201(s) of the 
FD&C Act that were already introduced into interstate commerce before 
the effective date of a final rule (we assume, in the PRIA, that a 
streamlined submission would require between 10 percent and 25 percent 
of the time expenditure of a GRAS notice (180 hours), with a central 
estimate of 17.5 percent to arrive at the estimate of 31.5 hours to 
prepare a streamlined submission (180 hours x 17.5 percent). 
Accordingly, we calculate the burden for this activity to be 77,376 
hours (2,418 submissions x 32 hours). We believe that this will be a 
one-time burden because these streamlined submissions are time-limited 
and would only be available for 1 year after the effective date of a 
final rule.
    We estimate the remaining 62 respondents would be preparing a 
submission for certain substances purported to be GRAS based on an 
independent conclusion of GRAS status for animal food (1,028 unique 
firms with independent conclusions of GRAS status--966 respondents 
preparing a submission for certain substances purported to be GRAS 
based on an independent conclusion of GRAS status for human food). In 
table 10 of the PRIA, we estimate that each respondent will prepare 
approximately 2.5 submissions for certain substances purported to be 
GRAS based on an independent conclusion of GRAS status that were 
already introduced into interstate commerce before the effective date 
of the final rule. Provided that each respondent will prepare 2.5 
submissions, we calculated that there will be 155 responses (62 
respondents x 2.5 submissions per respondent). In table 10 of the PRIA, 
we estimate that it will take approximately 32 hours (rounded up from 
31.5) to prepare a submission for certain substances purported to be 
GRAS based on an independent conclusion of GRAS status that were 
already introduced into interstate commerce before the effective date 
of a final rule. Accordingly, we estimate the burden for this activity 
to be 4,960 hours (155 submissions x 32 hours). We believe that this 
will be a one-time burden because the option to make streamlined 
submissions would only be available for 1 year after the effective date 
of a final rule.
    To ensure that comments on information collection are received, OMB 
recommends that written comments be submitted through reginfo.gov (see 
ADDRESSES). All

[[Page 51872]]

comments should be identified with the title of the information 
collection.
    In compliance with the Paperwork Reduction Act of 1995 (44 U.S.C. 
3407(d)), we have submitted the information collection provisions of 
this proposed rule to OMB for review. These information collection 
requirements will not be effective until FDA publishes a final rule, 
OMB approves the information collection requirements, and the rule goes 
into effect. FDA will announce OMB approval of these requirements in 
the Federal Register.

XI. Federalism

    We have analyzed this proposed rule in accordance with the 
principles set forth in Executive Order 13132. We have determined that 
the proposed rule does not contain policies that have substantial 
direct effects on the States, on the relationship between the National 
Government and the States, or on the distribution of power and 
responsibilities among the various levels of government. Accordingly, 
we conclude that the rule does not contain policies that have 
federalism implications as defined in the Executive order and, 
consequently, a federalism summary impact statement is not required.

XII. Consultation and Coordination With Indian Tribal Governments

    We have analyzed this proposed rule in accordance with the 
principles set forth in Executive Order 13175. We have tentatively 
determined that the rule does not contain policies that would have a 
substantial direct effect on one or more Indian Tribes, or the 
relationship between the Federal Government and Indian Tribes, or on 
the distribution of power and responsibilities between the Federal 
Government and Indian Tribes. FDA invites comments from tribal 
officials on any potential impact on Indian Tribes from this proposed 
action.

    The revisions and additions read as follows:


Sec.  170.30  Eligibility for classification as generally recognized as 
safe (GRAS).

* * * * *
    (c) * * *
    (2) A substance used in food before January 1, 1958, may be 
generally recognized as safe through experience based on its common use 
in food when that use occurred exclusively or primarily outside of the 
United States if the information about the experience establishes that 
the substance is safe under the conditions of its intended use within 
the meaning of section 201(u) of the Act (see also Sec.  170.3(i)). 
Common use in food before January 1, 1958, that occurred outside of the 
United States must be documented by published or other information and 
must be corroborated by information from a second, independent source 
that confirms the history and circumstances of use of the substance. 
The information used to document and to corroborate the history and 
circumstances of use of the substance must be generally available; that 
is, it must be widely available in the country in which the history of 
use has occurred and readily available to interested qualified experts 
in the United States.
    (d) The food ingredients listed as GRAS in part 182 of this chapter 
or affirmed as GRAS in part 184 or part 186 of this chapter do not 
include all substances that are generally recognized as safe for their 
intended use in food. Because of the large number of substances, the 
intended use of which results or may reasonably be expected to result, 
directly or indirectly, in their becoming a component or otherwise 
affecting the characteristics of food, it is impracticable to list in 
part 182 of this chapter or affirm in part 184 or part 186 of this 
chapter all such substances that are GRAS. A food ingredient of natural 
biological origin that has been widely consumed for its nutrient 
properties in the United States before January 1, 1958, without known 
detrimental effects, which is subject only to conventional processing 
as practiced before January 1, 1958, and for which no known safety 
hazards exists, will ordinarily be regarded as GRAS without specific 
inclusion in parts 182, 184, or 186 of this chapter.
    (e) All affirmations of GRAS status or determinations of food 
additive status or prior sanction status must be handled pursuant to

Sec.  170.38  Determination of food additive status.

    (a) FDA may determine that a substance is not GRAS under the 
conditions of its intended use and is not otherwise excepted from the 
definition of a food additive. If FDA determines that a substance is a 
food additive under the conditions of intended use, the substance and 
its use or intended use are subject to section 409 of the Act.
    (b) For substances listed or affirmed as GRAS in parts 182, 184, or 
186 of this chapter:
    (1) FDA, on its own initiative or on the petition of any person, 
pursuant to part 10 of this chapter, may issue a notice in the Federal 
Register proposing to determine that a substance is not GRAS under the 
conditions of its intended use and is a food additive subject to 
section 409 of the Act. Any petition must include all relevant data and 
information of the type described in Sec.  171.130(b) of this chapter. 
FDA will place all the data and information on which it relies on 
public file in the office of the Dockets Management Staff and will 
include in the Federal Register notice the name of the substance, its 
known uses, and a summary of the basis for the determination.
    (2) The Federal Register notice will allow a period of 60 days 
during which any interested person may review the data and information 
and/or file comments with the Dockets Management Staff. Copies of all 
comments are available for examination in the Dockets Management 
Staff's office.
    (3) If FDA concludes that there is a lack of convincing evidence 
that the substance is GRAS under the conditions of its intended use, 
FDA will amend or repeal the relevant regulation in parts 182, 184, or 
186 of this chapter, as appropriate.
    (c) For a use of a substance for which FDA has issued a no 
questions letter as defined in Sec.  170.203 in response to a GRAS 
notice, FDA may send the notifier (see Sec.  170.203) questions about 
their GRAS conclusion in accordance with Sec.  170.265(c). If FDA later 
determines that such substance is not GRAS under the conditions of its 
intended use, FDA will make public the basis for this determination and 
update or rescind the no questions letter.
    (d) For a use of a substance not covered by paragraphs (b) or (c) 
of this section, if FDA determines that such substance is not GRAS 
under the conditions of its intended use, FDA will make public the 
basis for this determination. The fact that FDA has not made such a 
determination does not mean that a substance is GRAS under the 
conditions of its intended use.

    The revisions read as follows:


Sec.  170.39  Threshold of regulation for substances used in food or as 
a food-contact substance.

    (a) A substance used in food or as a food-contact substance will be 
exempted from regulation as a food additive or from the GRAS 
notification requirement under Sec.  170.205 because the substance 
becomes a component of food at levels that are below the threshold of 
regulation if:
    (1) The substance has not been shown to be a carcinogen in humans 
or animals, and there is no reason, based on the chemical structure of 
the substance, to suspect that the substance is a carcinogen. The 
substance must also not contain a carcinogenic impurity or, if it does, 
must not contain a carcinogenic impurity with a lifetime cancer risk 
greater than one in one million, when calculated using a 
TD50 value or another approach based on chronic feeding 
studies reported in the scientific literature or otherwise available to 
FDA, when present in the diet at 0.025 micrograms per kilogram 
bodyweight per day. (The TD50, for purposes of this section, 
is the feeding dose that causes cancer in 50 percent of the test 
animals when corrected for tumors found in control animals. A 
TD50 of 6.25 milligrams per kilogram bodyweight per day 
equates to a lifetime cancer risk of less than one in one million when 
present in the diet at 0.025 micrograms per kilogram bodyweight per 
day. If more than one TD50 value has been reported in the 
scientific literature for a substance, FDA will use the lowest 
appropriate TD50 value in its review.);
    (2) The substance presents no other health or safety concerns 
because:
    (i) The use in question has been shown to result in or may be 
expected to result in dietary exposure levels at or below 0.025 
micrograms per kilogram bodyweight per day; or
    (ii) The substance is currently regulated for direct addition into 
food, and the dietary exposure to the substance resulting from the 
proposed use is at or below 1 percent of the acceptable daily intake as 
determined by safety data in FDA's files or from other appropriate 
sources; and
    (3) The substance use has no significant adverse impact on the 
environment.
    (b) Notwithstanding paragraph (a) of this section, FDA may decline 
to grant an exemption in those cases in which available information 
establishes that the proposed use may pose a public health risk. The 
reasons for FDA's decision to decline to grant an exemption will be 
explained in FDA's response to the person who submitted the request 
(the requestor) to exempt a use of a substance from regulation as a 
food additive or from the GRAS notification requirement under Sec.  
170.205.
    (c) A request for FDA to exempt a use of a substance from 
regulation as a food additive or from the GRAS notification requirement 
under Sec.  170.205 must include the following information (if part of 
the submitted material is in a foreign language, it must be accompanied 
by an English translation verified to be complete and accurate in 
accordance with Sec.  10.20(c)(2) of this chapter):
    (1) * * *
    (2) Detailed information on the conditions of use of the substance;
    (3) A clear statement as to whether the request for exemption from 
regulation as a food additive is based on the fact that the use of the 
substance results in a dietary exposure level at or below 0.025 
micrograms per kilogram bodyweight per day, or on the fact that it 
involves the use of a regulated direct food additive for which the 
dietary exposure is at or below 1 percent of the acceptable dietary 
intake (ADI);
    (4) Data that will enable FDA to estimate the dietary exposure 
resulting from the proposed use of the substance;
    (5) The results of an analysis of existing toxicological 
information on the substance and its impurities. This information on 
the substance is needed to show whether an animal carcinogen bioassay 
has been carried out, or whether there is some other basis for 
suspecting that the substance is a carcinogen or potent toxin. This 
type of information on the impurities is needed to show whether any of 
them are carcinogenic, and, if carcinogenic, whether their lifetime 
cancer risk is less than one in one million when present in the diet at 
0.025 micrograms per kilogram bodyweight per day in accordance with 
paragraph (a)(1) of this section; and
    (6) * * *
    (d) Data to be reviewed under this section must be submitted 
electronically through the Centralized Online Submission Module, unless 
provided with a waiver to submit on paper. Send a request for a waiver 
to the Office of Pre-market Additive Safety, Human Foods Program, Food 
and Drug Administration, 5001 Campus Dr., College Park, MD 20740.
    (e) FDA will inform the requestor whether the use is exempt from 
regulation as a food additive or from the GRAS notification requirement 
under Sec.  170.205. Although a use that results in a dietary exposure 
at or below the threshold of regulation will not be the subject of a 
regulation published in the Federal Register and will not appear in the 
Code of Federal Regulations, FDA will maintain a publicly available 
list of substances and their use exempted from regulation as food 
additives or from the GRAS notification requirement under Sec.  
170.205. The list will not include any trade names. The list will 
enable interested persons to see the types of uses being exempted under 
the regulation. Interested persons may also obtain a copy of the list 
of exempted substances by contacting the Food and Drug Administration's 
Office of Food Additive Safety (HFS-200), 5001 Campus Dr., College 
Park, MD 20740. For actions requiring an environmental assessment, 
FDA's finding of no significant impact and the evidence supporting that 
finding, contained in the petitioner's environmental assessment, also 
will be available for public inspection at the Dockets Management Staff 
in accordance with Sec.  25.51(b)(2) of this chapter. Requests for 
copies of releasable information contained in submissions requesting 
exemptions from the food additive regulations or from the GRAS 
notification requirement under Sec.  170.205 will be handled in 
accordance with the Freedom of Information Act procedures in part 20 of 
this chapter. Data and information that fall within the definitions of 
a trade secret or confidential commercial or financial information are 
not available for public disclosure in accordance with Sec.  20.61(c) 
of this chapter.
    (f) If FDA receives significant new information that raises 
questions about the dietary exposure or the safety of a substance that 
FDA has exempted from regulation, FDA may reevaluate the substance. If 
FDA tentatively concludes that the information that is available about 
the substance no longer supports an exemption for the proposed use of 
the substance from the GRAS or food additive regulations, FDA will 
notify any persons that requested an exemption for the substance of its 
tentative decision. FDA will give the requestor an opportunity to show 
why the use of the substance should not be regulated under the food 
additive provisions of the Act. If the requestor fails to respond 
adequately to the new evidence, FDA will notify them that further use 
of the substance in question for the particular use will require a food 
additive regulation, an effective premarket notification for a food-
contact substance, or a GRAS notice. This

[[Page 51876]]

notification will be made publicly available. FDA recognizes that 
manufacturers other than those that made a request for exemption may 
also be using exempted substance under conditions of use that are 
similar to those for which the exemption was issued. Because only the 
requestor will be notified as part of the revocation process described 
in this section, FDA plans to notify other manufacturers by means of a 
notice published in the Federal Register of its decision to revoke an 
exemption issued for a specific use of a substance in food or as a 
food-contact substance.

under the conditions of its intended use. A no questions letter is 
neither an affirmation by FDA that the notified substance is GRAS for 
its intended conditions of use under Sec.  170.35, nor a published 
finding under section 721(b)(4) of the Act declaring the use of such

    (4) The intended use of the substance has been considered by FDA 
through an established FDA process to evaluate the potential presence 
of unapproved food additives, and documentation made publicly available 
by FDA through that process does not recommend or otherwise identify 
the need to submit a GRAS notice;
    (5) The intended use of the substance is the subject of an 
exemption under the threshold of regulation process described in Sec.  
170.39;
    (6) There is an effective premarket notification for a food-contact 
substance (FCN) which covered the substance under conditions of its 
intended use, and the substance in interstate commerce originates from 
the manufacturer or supplier listed in the effective FCN; or
    (7) Information about the conditions of use of the substance has 
been submitted in accordance with Sec.  170.305 and the submission is 
included on a public list maintained by FDA, unless FDA issues a 
determination that a GRAS notice or food additive petition must be 
submitted for the intended use of a substance.
    (c) Uses of substances that are excluded from the definition of a 
food additive in section 201(s)(1) through (6) of the Act cannot be the

    (a) Submissions for pre-[EFFECTIVE DATE OF THE FINAL RULE] 
substances. For a substance introduced into interstate commerce before 
[EFFECTIVE DATE OF THE FINAL RULE] under the GRAS provision of section 
201(s) of the Act, a person may submit information regarding the 
substance and its conditions of use in accordance with this subpart 
instead of submitting a GRAS notice under Sec.  170.205.
    (b) When a submission is not allowed. A submission under this 
subpart may not concern any conditions of use of a substance that are 
the subject of:
    (1) An insufficient basis letter (see Sec.  170.303); or
    (2) A determination by FDA that the substance is not GRAS under the 
conditions of its intended use.
    (c) Parts of a submission and how to submit.
    (1) A submission must include the following:

    (iv) Evidence of presence in interstate commerce before [EFFECTIVE 
DATE OF THE FINAL RULE]; and
    (v) If applicable, where FDA sent a cease to evaluate letter in 
response to a submitter's previous GRAS notice (GRN), provide that file 
number (GRN No.) as part of the submission.
    (2) A submission may inform us of the statutory basis for the 
conclusion of GRAS status (i.e., through scientific procedures in 
accordance with Sec.  170.30(a) and (b) or through experience based on 
common use in food in accordance with Sec.  170.30(a) and (c)).
    (3) This information must be submitted to FDA electronically 
through the Centralized Online Submission Module by [DATE 1 YEAR AFTER 
EFFECTIVE DATE OF THE FINAL RULE], unless provided with a waiver to 
submit on paper. Send a request for a waiver to the Office of Pre-
market Additive Safety, Human Foods Program, Food and Drug 
Administration, 5001 Campus Dr., College Park, MD 20740. Submissions 
under this subpart will not be accepted after [DATE 1 YEAR AFTER 
EFFECTIVE DATE OF THE FINAL RULE].
    (d) What FDA will do with a submission.
    (1) FDA will post information that meets the requirements for a 
submission as specified in Sec.  170.305(c)(1) and (c)(2) in a publicly 
available list in accordance with part 20 of this chapter. The posting 
of this information does not mean that FDA has reviewed the GRAS status 
of the substance's conditions of intended use.

[[Page 51878]]

    (2) FDA may ask the submitter questions about their submission.
    (3) FDA may issue a determination that a GRAS notice or food 
additive petition must be submitted for the intended use of a substance

    (c) * * *
    (2) A substance used in food before January 1, 1958, may be 
generally recognized as safe through experience based on its common use 
in food when that use occurred exclusively or primarily outside of the 
United States if the information about the experience establishes that 
the substance is safe under the conditions of its intended use within 
the meaning of section 201(u) of the Act (see also Sec.  570.3(i)) for 
both the target animal and for humans consuming human food derived from 
food-producing animals. Common use in food before January 1, 1958, that 
occurred outside of the United States must be documented by published 
or other information and must be corroborated by information from a 
second, independent source that confirms the history and circumstances 
of use of the substance. The information used to document and to 
corroborate the history and circumstances of use of the substance must 
be generally available; that is, it must be widely available in the 
country in which the history of use has occurred and readily available 
to interested qualified experts in the United States.
    (d) The food ingredients listed as GRAS in part 582 of this chapter 
or affirmed as GRAS in part 584 of this chapter do not include all 
substances that are generally recognized as safe for their intended use 
in food. Because of the large number of substances, the intended use of 
which results or may reasonably be expected to result, directly or 
indirectly, in their becoming a component or otherwise affecting the 
characteristics of food, it is impracticable to list in part 582 of 
this chapter or affirm in part 584 of this chapter all such substances 
that are GRAS. A food ingredient of natural biological origin that has 
been widely consumed for its nutrient properties in the United States 
before January 1, 1958, without known detrimental effects, which is 
subject only to conventional processing as practiced before January 1, 
1958, and for which no known safety hazard exists, will ordinarily be 
regarded as GRAS without specific inclusion in parts 582 or 584 of this 
chapter.
* * * * *
    (h) If a substance is affirmed as GRAS in part 584 of this chapter 
with no limitation other than good manufacturing practice:
    (1) It will be regarded as GRAS if its conditions of use are not 
significantly different from those reported in the regulation as the 
basis on which the GRAS status of the substance was affirmed; or
    (2) If the conditions of use are significantly different, the 
regulation may not be relied on as authorizing such use.

    The revisions and addition read as follows:


Sec.  570.38  Determination of food additive status.

    (a) FDA may determine that a substance is not GRAS under the 
conditions of its intended use and is not otherwise excepted from the 
definition of a food additive. If FDA determines that a substance is a 
food additive under the conditions of intended use, the substance and 
its use or intended use are subject to section 409 of the Act.
    (b) For substances listed or affirmed as GRAS in parts 582 or 584 
of this chapter:
    (1) FDA, on its own initiative or on the petition of any interested 
person, pursuant to part 10 of this chapter, may issue a notice in the 
Federal Register proposing to determine that a substance is not GRAS 
under the conditions of its intended use and is a food additive subject 
to section 409 of the Act. Any petition must include all relevant data 
and information of the type described in Sec.  571.130(b) of this 
chapter. FDA will place all the data and information on which it relies 
on public file in the office of the Dockets Management Staff and will 
include in the Federal Register notice the name of the substance, its 
known uses, and a summary of the basis for the determination.
    (2) The Federal Register notice will allow a period of 60 days 
during which any interested person may review the data and information 
and/or file comments with the Dockets Management Staff. Copies of all 
comments are available for examination in the Dockets Management 
Staff's office.
    (3) If FDA concludes that there is a lack of convincing evidence 
that the substance is GRAS under the conditions of its intended use, 
FDA will amend or repeal the relevant regulation in part 582 or 584 of 
this chapter, as appropriate.
    (c) For a use of a substance for which FDA has issued a no 
questions letter as defined in Sec.  570.203 in response to a GRAS 
notice, FDA may send the notifier (see Sec.  570.203) questions about 
their GRAS conclusion in accordance with Sec.  570.265(c). If FDA later 
determines that such substance is not GRAS under the conditions of its 
intended use, FDA will make public the basis for this determination and 
update or rescind the no questions letter.
    (d) For a use of a substance not covered by paragraphs (b) or (c) 
of this section, if FDA determines that such substance is not GRAS 
under the conditions of its intended use, FDA will make public the 
basis for this determination. The fact that FDA has not made such a 
determination does not mean that a substance is GRAS under the 
conditions of its intended use.

Sec.  570.203  Definitions.

* * * * *
    GRAS means generally recognized as safe (see Sec.  570.3(i)).
    GRAS notice means a submission under Sec.  570.205 that informs us 
of your view that a substance is not subject to the premarket review 
and approval requirements for food additives under section 409 of the 
Act based on your conclusion that the substance is GRAS under the 
conditions of its intended use in accordance with Sec.  570.30.
    Inventory means an online repository where FDA makes public certain 
information related to GRAS notices.
    No questions letter means a letter from FDA, sent in response to a 
GRAS notice, which states that, based on the information you provided, 
as well as other information available to FDA, we have no questions at 
this time regarding your conclusion that the notified substance is GRAS 
under the conditions of its intended use. A no questions letter is 
neither an affirmation by FDA that the notified substance is GRAS for 
its intended conditions of use under Sec.  570.35, nor a published 
finding under section 721(b)(4) of the Act declaring the use of such 
substance exempt from the term ``food additive'' because of its being 
GRAS.
