CONSUMER PRODUCT SAFETY COMMISSION

16 CFR Part 1233

[Docket No. CPSC-2015-0016]


Safety Standard for Portable Hook-On Chairs

AGENCY: Consumer Product Safety Commission.

ACTION: Direct final rule.

-----------------------------------------------------------------------

SUMMARY: In March 2016, the U.S. Consumer Product Safety Commission 
(CPSC or Commission) published a consumer product safety standard for 
portable hook-on chairs based on the ASTM voluntary standard for 
portable hook-on chairs. Currently, CPSC's mandatory standard 
incorporates by reference ASTM F1235-18, Standard Consumer Safety 
Specification for Portable Hook-on Chairs. The Consumer Product Safety 
Improvement Act of 2008 (CPSIA) sets forth a process for updating 
mandatory standards for durable infant or toddler products that are 
based on a voluntary standard, when a voluntary standards organization 
revises the standard. In January 2026, ASTM published a revised 
voluntary standard. This direct final rule updates the mandatory 
standard for portable hook-on chairs to incorporate by reference the 
2025 version of ASTM F1235.

DATES: The rule is effective on July 19, 2026, unless the Commission 
receives a significant adverse comment by April 29, 2026. If the 
Commission receives such a comment, it will publish a notice in the 
Federal Register, withdrawing this direct final rule before its 
effective date. The incorporation by reference of the publication 
listed in this rule is approved by the Director of the Federal Register 
as of July 19, 2026.

ADDRESSES: You can submit comments, identified by Docket No. CPSC-2015-
0016, by any of the following methods:

SUPPLEMENTARY INFORMATION:

I. Statutory Authority and Background

A. Statutory Authority

    Section 104(b) of the CPSIA requires the Commission to assess the 
effectiveness of voluntary standards for durable infant or toddler 
products and adopt mandatory standards for these products. 15 U.S.C. 
2056a(b)(1). Mandatory standards must be ``substantially the same as'' 
applicable voluntary standards, or they may be ``more stringent'' than 
the voluntary standards, if the Commission determines that more 
stringent requirements would further reduce the risk of injury 
associated with the products. Id. Accordingly, mandatory standards may 
be based, in whole or in part, on a voluntary standard.
    Section 104(b)(4)(B) of the CPSIA specifies the process for when a 
voluntary standards organization revises a standard the Commission has 
incorporated by reference under section 104(b)(1). 15 U.S.C. 
2056a(b)(4)(B). First, the voluntary standards organization must notify 
the Commission of the revision. Once the Commission receives this 
notification, the Commission may reject or accept the revised standard. 
To reject a revised standard, the Commission must notify the voluntary 
standards organization within 90 days of receiving the notice of 
revision that the Commission has determined that the revised standard 
does not improve the safety of the consumer product and that CPSC is 
retaining the existing standard. If the Commission does not take this 
action, then the revised voluntary standard will be considered a 
consumer product safety standard issued under section 9 of the Consumer 
Product Safety Act (CPSA) (15 U.S.C. 2058), effective 180 days after 
the Commission received notification of the revision (or a later date 
specified by the Commission in the Federal Register). 15 U.S.C. 
2056a(b)(4)(B).

B. Safety Standard for Portable Hook-On Chairs

    Pursuant to section 104(b)(1) of the CPSIA, on March 28, 2016, the 
Commission published a mandatory consumer product safety standard that 
incorporated by reference ASTM F1235-15, Standard Consumer Safety 
Specification for Portable Hook-On Chairs. (81 FR 17062, March 28, 
2016). The standard covers performance requirements, test methods, and 
labeling requirements for portable hook-on chairs.
    The ASTM standard incorporated by CPSC defines a portable hook-on 
chair in section 1.3 as ``[u]sually a legless seat constructed to 
locate the occupant at a table in such a position and elevation so that 
the surface of the table can be used as a feeding surface for the 
occupant . . . [s]upported solely by the table on which it is 
mounted.'' Typical hook-on chairs consist of a fabric over a 
lightweight frame, with a device to mount the seat to a support 
surface, such as a table or counter. Some hook-on chairs fold for easy 
storage or transport, and some include a removable tray that can be 
used in conjunction with a table.
    On September 24, 2018, the Commission published a direct final rule 
revising the CPSC's mandatory standard for portable hook-on chairs. The 
revision incorporated by reference the most recent version of the 
applicable standard (ASTM F1235-18) at that time (83 FR 48219, Sept. 
24, 2018). The updated standard included new requirements addressing 
fabric passive crotch restraints.
    On January 20, 2026, ASTM notified the Commission that it had 
approved and published a newly revised version of the voluntary 
standard for portable hook-on chairs, ASTM F1235-25. As explained in 
sections II.A and II.B of this preamble, ASTM F1235-25 contains 
substantive revisions that improve the safety of portable hook-on 
chairs. The substantive changes add requirements for batteries, battery 
compartments, and AC adapters. The Commission determines that these 
changes improve the safety of portable hook-on chairs because of the 
addition of performance and marking requirements for batteries, battery 
compartments, and AC adapters that are consistent with other juvenile 
products. Also, the standard's language was updated to align with ASTM 
F15 Ad Hoc Language task group recommendations for consistency with 
other ASTM juvenile product standards. The Commission determines that 
these changes are safety neutral.
    On January 29, 2026, the Commission published in the Federal 
Register a Notice of Availability, requesting comment on whether the 
2025 revision improves the safety of portable hook-on chairs. 91 FR 
3846. CPSC received one comment that was out of scope.
    Based on staff's evaluation of ASTM F1235-25, the Commission will 
allow ASTM F1235-25 to become the new consumer product safety standard 
for portable hook-on chairs. Pursuant to CPSIA section 104, the revised 
voluntary standard will take effect as the new mandatory standard for 
portable hook-on chairs on July 19, 2026. 15 U.S.C. 2056a(b)(4)(B). 
This direct final rule updates 16 CFR part 1233 to incorporate by 
reference the revised voluntary standard, ASTM F1235-25.

II. Revisions to ASTM F1235

    ASTM F1235-25 includes several additions and revisions to ASTM 
F1235-18, including new performance requirements, a test method, and 
marking requirements for batteries, battery compartments, and AC 
adapters, as well as ad-hoc language and editorial revisions that do 
not alter substantive requirements in the standard or impact safety. 
The Commission considers the revisions in ASTM F1235-25 to be an 
improvement to the safety of portable hook-on chairs because the 
revised standard added performance and marking requirements for 
batteries, battery compartments, and AC adapters.

[[Page 15538]]

A. Performance and Testing Requirements

    In section 6.8 of ASTM F1235-25, ASTM added requirements for 
battery compartments to contain leaks, prevent charging of non-
rechargeable batteries through design or circuitry, limit surface 
temperatures to 160 [deg]F (71 [deg]C) without causing fire or leakage, 
and ensure AC adapters meet national safety standards with output below 
30 VDC and 8 amps.
    In section 7.14 of ASTM F1235-25, ASTM added the peak temperature 
and battery leakage test. The test ensures that battery-powered 
functions operate at maximum intensity using specified battery types or 
AC power, under controlled conditions, to monitor peak temperature and 
verify safety without disabling protective features.

B. Warnings and Instructions

    In section 8.6 of ASTM F1235-25, ASTM added marking requirements 
for portable hook-on chairs with batteries. The section states that 
products with battery compartments must be permanently and clearly 
labeled with battery specifications, and if they use non-replaceable 
batteries accessible by common tools, they must also be marked to 
indicate the batteries are not replaceable or include that information 
in the instructions.
    In section 9.4 of ASTM F1235-25, ASTM added cautionary statement 
requirements that require products using replaceable batteries to 
include cautionary instructions to prevent leaks and injuries, 
emphasizing proper storage, disposal, and consistent battery 
replacement practices.
    The requirements discussed above to ASTM F1235 improve the product 
safety of portable hook-on chairs by adding new performance, warning 
and instruction requirements that mitigate hazards associated with 
battery-powered features. While most hook-on chairs currently lack such 
features, these revisions proactively address risks observed in other 
juvenile products and align with established ASTM standards for 
juvenile products.

C. Other Revisions

    ASTM F1235-25 includes several language revisions to reflect 
current ``ad hoc'' language recommendations, which are recommendations 
from the ASTM F15 Ad Hoc Language task group to maintain consistent 
language for requirements in ASTM juvenile product standards. Examples 
include requirements addressing scissoring, shearing, and pinching 
hazards; permanency of labels and warnings; and protective components. 
The modifications are consistent with CPSC's interpretation of the 
requirements in the current standard and therefore do not impact 
safety.
    ASTM F1235-25 also includes editorial revisions, such as adding the 
parts of speech next to the terms in the terminology section, adding 
dimensions to numbers (e.g., ``6 x 6 in.'' to ``6 in. x 6 in.''), and 
updates to section and figure numbers to reflect revised and new 
sections. These revisions do not impact safety because they do not 
alter any substantive requirements in the standard.

III. Incorporation by Reference

    Section 1233.2 of the direct final rule incorporates by reference 
ASTM F1235-25. The Office of the Federal Register (OFR) has regulations 
regarding incorporation by reference. 1 CFR part 51. Under these 
regulations, agencies must discuss, in the preamble to a final rule, 
ways in which material the agency incorporates by reference is 
reasonably available to interested parties, and how interested parties 
can obtain the material. In addition, the preamble to the final rule 
must summarize the material. 1 CFR 51.5(b).
    In accordance with the OFR regulations, section II of this preamble 
summarizes the revised provisions of ASTM F1235-25 that the Commission 
incorporates by reference into 16 CFR part 1233. The standard is 
reasonably available to interested parties in several ways. Until the 
direct final rule takes effect, a read-only copy of ASTM F1235-25 is 
available for viewing on ASTM's website at: https://www.astm.org/CPSC.htm. Once the rule takes effect, a read-only copy of the standard 
will be available for viewing on the ASTM website at: https://www.astm.org/READINGLIBRARY/. Additionally, interested parties can 
purchase a copy of ASTM F1235-25 from ASTM International, 100 Barr 
Harbor Drive, P.O. Box C700, West Conshohocken, PA 19428-2959 USA; 
phone: 610-832-9585; www.astm.org. Finally, interested parties can 
schedule an appointment to inspect a copy of the standard at CPSC's 
Office of the Secretary, U.S. Consumer Product Safety Commission, 4330 
East-West Highway, Bethesda, MD 20814, telephone: 301-504-7479; email: 
[email protected].

IV. Certification

    Section 14(a) of the CPSA (15 U.S.C. 2063(a)) requires 
manufacturers, including importers, of products subject to a consumer 
product safety rule under the CPSA, or to a similar rule, ban, 
standard, or regulation under any other act enforced by the Commission, 
to certify that the products comply with all applicable CPSC 
requirements. 15 U.S.C. 2063(a). Such certification must be based on a 
test of each product, or on a reasonable testing program, or, for 
children's products, on tests of a sufficient number of samples by a 
CPSC-accepted third party conformity assessment body accredited to test 
according to the applicable requirements. As noted, standards issued 
under section 104(b)(1)(B) of the CPSIA are ``consumer product safety 
standards.'' Thus, they are subject to the testing and certification 
requirements of section 14 of the CPSA.
    Because portable hook-on chairs are children's products, a CPSC-
accepted third party conformity assessment body must test samples of 
the products. Products subject to part 1233 also must comply with all 
other applicable CPSC requirements, such as the lead content 
requirements in section 101 of the CPSIA,\1\ the phthalates 
prohibitions in section 108 of the CPSIA,\2\ 16 CFR part 1307, the 
tracking label requirements in section 14(a)(5) of the CPSA,\3\ and the 
consumer registration form requirements in section 104(d) of the 
CPSIA.\4\ ASTM F1235-25 makes no changes that would impact any of these 
existing requirements.

---------------------------------------------------------------------------

V. Notice of Requirements

    In accordance with section 14(a)(3)(B)(vi) of the CPSA (15 U.S.C. 
2063(a)(3)(B)(vi)), the Commission previously published a notice of 
requirements (NOR) for accreditation of third-party conformity 
assessment bodies (third party labs) for testing portable hook-on 
chairs. 81 FR 17062 (March 28, 2016). The NOR provided the criteria and 
process for CPSC to accept accreditation of third-party conformity 
assessment bodies for testing portable hook-on chairs to 16 CFR part 
1233. The NORs for all mandatory standards for durable infant or 
toddler products are listed in the Commission's rule, ``Requirements 
Pertaining to Third Party Conformity Assessment Bodies,'' codified in 
16 CFR part 1112. The NOR for accreditation of third-party labs for 
testing for portable hook-on chairs is codified at 16 CFR 
1112.15(b)(40).
    ASTM F1235-25 changed the testing requirements for portable hook-on 
chairs by adding a peak temperature and battery leakage test. The new 
peak temperature and battery leakage test is included in other juvenile 
product

[[Page 15539]]

standards and can be conducted by accredited testing laboratories, as 
these facilities generally possess the capability to evaluate a range 
of different juvenile products. Therefore, testing laboratories that 
have demonstrated competence for testing in accordance with other 
juvenile product standards and ASTM F1235-18 will have the competence 
to test in accordance with the revised standard ASTM F1235-25. Based on 
the above, the Commission considers the existing CPSC-accepted 
laboratories for testing to ASTM F1235-18 to be capable of testing to 
ASTM 1235-25 as well. Accordingly, the existing NOR for this standard 
will remain in place, and CPSC-accepted third party conformity 
assessment bodies are expected to update the scope of the testing 
laboratories' accreditations to reflect the revised standard in the 
normal course of renewing their accreditations.

VI. Direct Final Rule Process

    The Commission is issuing this rule as a direct final rule. 
Although the Administrative Procedure Act (APA; 5 U.S.C. 551-559) 
generally requires agencies to provide notice of a rule and an 
opportunity for interested parties to comment on it, section 553 of the 
APA provides an exception when the agency ``for good cause finds'' that 
notice and comment are ``impracticable, unnecessary, or contrary to the 
public interest.'' Id. 553(b)(B).
    The purpose of this direct final rule is to update the reference in 
the Code of Federal Regulations (CFR) so that it reflects the version 
of the standard that takes effect by statute. This rule updates the 
reference in the CFR, but under the terms of the CPSIA, ASTM F1235-25 
takes effect as the new CPSC standard for portable hook-on chairs, even 
if the Commission does not issue this rule. Thus, public comments would 
not lead to substantive changes to the standard or to the effect of the 
revised standard as a consumer product safety rule under section 104(b) 
of the CPSIA. Under these circumstances, notice and comment are 
unnecessary.
    In Recommendation 2024-6, the Administrative Conference of the 
United States (ACUS) endorses direct final rulemaking as an appropriate 
procedure to expedite rules that are noncontroversial and that are not 
expected to generate significant adverse comments. See 89 FR 106406 
(Dec. 30, 2024). ACUS recommends that agencies use the direct final 
rule process when they act under the ``unnecessary'' prong of the good 
cause exemption in 5 U.S.C. 553(b)(B). 89 FR 106406, 106409. ACUS also 
explains that notice and comment may be ``unnecessary'' when the agency 
lacks discretion regarding the substance of the rule. Id. at 106408. As 
noted, this rule updates a reference in the CFR to reflect a change 
that occurs by statute. Consistent with the ACUS recommendation the 
Commission is publishing this rule as a direct final rule, because CPSC 
does not expect any significant adverse comments.
    Unless CPSC receives a significant adverse comment within 30 days 
of this notification, the rule will become effective on July 19, 2026. 
In accordance with ACUS's recommendation, the Commission considers a 
significant adverse comment to be one where the commenter explains why 
the rule would be inappropriate, ``including challenges to the rule's 
underlying premise or approach,'' or where the commenter explains why 
the rule would be ineffective or unacceptable without change. Id. at 
106409. As noted, this rule updates a reference in the CFR to reflect a 
change that occurs by statute.
    If the Commission receives a significant adverse comment, the 
Commission will withdraw this direct final rule. Depending on the 
comment and other circumstances, the Commission may then incorporate 
the adverse comment into a subsequent direct final rule or publish a 
notice of proposed rulemaking, providing an opportunity for public 
comment.

VII. Regulatory Flexibility Act

    The Regulatory Flexibility Act (RFA; 5 U.S.C. 601-612) generally 
requires agencies to review proposed and final rules for their 
potential economic impact on small entities, including small 
businesses, and prepare regulatory flexibility analyses. 5 U.S.C. 603, 
604. The RFA applies to any rule that is subject to notice and comment 
procedures under section 553 of the APA. 5 U.S.C. 601-612. As discussed 
in section VI of this preamble regarding the Direct Final Rule Process, 
the Commission has determined that notice and the opportunity to 
comment are unnecessary for this rule. Therefore, the RFA does not 
apply. The Commission also notes the limited nature of this document, 
which updates the incorporation by reference to reflect the mandatory 
CPSC standard that takes effect under section 104 of the CPSIA.

VIII. Paperwork Reduction Act

    The current mandatory standard for portable hook-on chairs includes 
labeling requirements that constitute a ``collection of information,'' 
as defined in the Paperwork Reduction Act (PRA; 44 U.S.C. 3501-3521). 
While the revised mandatory standard adds marking and labeling 
requirements for portable hook-on chairs, the new requirements would 
not materially add to the burden hours because the products already 
require marking and labeling. The Commission took the steps required by 
the PRA for information collections when it promulgated 16 CFR part 
1233, and the marking, labeling, and instructional literature for 
portable hook-on chairs are currently approved under OMB Control Number 
3041-0159. Because the information collection burden is essentially 
unchanged, the revision does not affect the information collection 
requirements or approval related to the standard. The agency will 
consider whether OMB Control number 3041-0159 should be revised for 
portable hook-on chairs in the next scheduled update.

IX. Environmental Considerations

    The Commission's regulations provide for a categorical exclusion 
from any requirement to prepare an environmental assessment or an 
environmental impact statement where they ``have little or no potential 
for affecting the human environment.'' 16 CFR 1021.5(c)(2). This rule 
falls within the categorical exclusion, so no environmental assessment 
or environmental impact statement is required.

X. Preemption

    Section 26(a) of the CPSA provides that where a consumer product 
safety standard is in effect and applies to a product, no state or 
political subdivision of a state may either establish or continue in 
effect a requirement dealing with the same risk of injury unless the 
state requirement is identical to the Federal standard. 15 U.S.C. 
2075(a). Section 26(c) of the CPSA also provides that states or 
political subdivisions of states may apply to CPSC for an exemption 
from this preemption under certain circumstances. Section 104(b) of the 
CPSIA deems rules issued under that provision ``consumer product safety 
standards.'' Therefore, once a rule issued under section 104 of the 
CPSIA takes effect, it will preempt in accordance with section 26(a) of 
the CPSA.

XI. Effective Date

    Under the procedure set forth in section 104(b)(4)(B) of the CPSIA, 
when a voluntary standards organization revises a standard that the 
Commission adopted as a mandatory standard, the revision becomes the 
CPSC standard 180 days after notification to the Commission, unless the 
Commission

[[Page 15540]]

determines that the revision does not improve the safety of the 
product, or the Commission sets a later date in the Federal Register. 
15 U.S.C. 2056a(b)(4)(B). The Commission is taking neither of those 
actions with respect to the revised standard for portable hook-on 
chairs. Therefore, ASTM F1235-25 automatically will take effect as the 
new mandatory standard for portable hook-on chairs on July 19, 2026, 
180 days after the Commission received notice of the revision. As a 
direct final rule, unless the Commission receives a significant adverse 
comment within 30 days of this notice, the rule will become effective 
on July 19, 2026.

XII. Congressional Review Act and Executive Order 12866

    Pursuant to the Congressional Review Act (CRA) and Executive Order 
(E.O.) 12866, the Office of Management and Budget's Office of 
Information and Regulatory Affairs has determined that this rule does 
not qualify as a ``major rule,'' as defined in 5 U.S.C. 804(2), and is 
not a significant regulatory action as defined under section 2(f) of 
E.O. 12866. To comply with the CRA, CPSC will submit the required 
information to each House of Congress and the Comptroller General.
