II. Background

    On July 30, 2025, the President signed Executive Order (E.O.) 14324 
(Suspending Duty-Free De Minimis Treatment For All Countries).\1\ Among 
other things, E.O. 14324 suspended the availability of the de minimis 
administrative exemption under 19 U.S.C. 1321(a)(2)(C) for most 
imports, to address the national emergencies declared in E.O. 14193 of 
February 1, 2025 (Imposing Duties To Address the Flow of Illicit Drugs 
Across Our Northern Border), E.O. 14194 of February 1, 2025 (Imposing 
Duties To Address the Situation at Our Southern Border), E.O. 14195 of 
February 1, 2025 (Imposing Duties To Address the Synthetic Opioid 
Supply Chain in the People's Republic of China), and E.O. 14257 of 
April 2, 2025 (Regulating Imports With a Reciprocal Tariff To Rectify 
Trade Practices That Contribute to Large and Persistent Annual United 
States Goods Trade Deficits).\2\ E.O. 14324 generally calls for 
shipments that qualified for the de minimis exemption prior to the 
effective date of the order, other than shipments sent through the 
international postal network, to be entered using an appropriate entry 
type in the Automated Commercial Environment (ACE) by a party qualified 
to make such entry.
---------------------------------------------------------------------------

    \1\ 90 FR 37775 (Aug. 5, 2025).
    \2\ For more information regarding these national emergency 
declarations, please see ``Notice of Implementation of the 
President's Executive Order 14324, Suspending Duty-Free De Minimis 
Treatment for All Countries'' at 90 FR 42418 (Sept. 2, 2025), which 
is CBP's notice effectuating Executive Order 14324, inter alia: 
Executive Order 14193, 90 FR 9113 (Feb. 7, 2025); Executive Order 
14194, 90 FR 9117 (Feb. 7, 2025); Executive Order 14195, 90 FR 9121 
(Feb. 7, 2025); and Executive Order 14257, 90 FR 15041 (Apr. 7, 
2025). As noted in Executive Order 14389, 91 FR 9437 (Feb. 20, 
2026), the national emergencies declared or described in the above 
orders remain in effect.
---------------------------------------------------------------------------

    On February 20, 2026, the United States Supreme Court decided 
Learning Resources, Inc. v. Trump, 607 U.S. __(2026), holding that the 
International Emergency Economic Powers Act (IEEPA), 50 U.S.C. 1701 et 
seq., does not authorize the President to impose additional tariffs. 
That decision did not address the suspension of the de minimis 
administrative exemption pursuant to IEEPA. In light of that decision, 
E.O. 14389 of February 20, 2026 (Ending Certain Tariff Actions),\3\ 
terminated the additional duties that had been imposed under IEEPA in

[[Page 37802]]

certain Executive Orders (including the Executive Orders listed in the 
preceding paragraph), while making clear that the national emergency 
declarations underlying the imposition of the tariffs remain ongoing 
and maintaining other measures adopted under those orders. On the same 
day, E.O. 14388 of February 20, 2026 (Continuing the Suspension of 
Duty-Free De Minimis Treatment for All Countries),\4\ continued the 
suspension of the duty-free de minimis exemption under 19 U.S.C. 
1321(a)(2)(C), including for shipments sent through the international 
postal network, and stated that CBP should continue to inspect such 
goods and collect applicable duties, taxes, fees, exactions, and 
charges on such shipments.
---------------------------------------------------------------------------

    \3\ 91 FR 9437 (Feb. 25, 2026).
    \4\ 91 FR 9433 (Feb. 25, 2026).
---------------------------------------------------------------------------

    Pursuant to section 2(b) of E.O. 14324, as revised by E.O. 14388, 
shipments sent through the international postal network that would 
otherwise qualify for the de minimis exemption under 19 U.S.C. 
1321(a)(2)(C) ``shall pass free of any duties except those specified in 
section 3 of this order,'' and without the preparation of an entry by 
CBP, ``until the effective date for the new entry process for postal 
shipments established by CBP and published in the Federal Register.'' 
Section 3 of E.O. 14324, as revised by E.O. 14388, established an 
interim process and new duty rates for covered products sent to the 
United States through the international postal network, discussed in 
more detail below, and directed that the duty rate ``shall be assessed 
until the expiration date of the temporary import surcharge established 
by Proclamation 11012 of February 20, 2026 (Imposing a Temporary Import 
Surcharge to Address Fundamental International Payment Problems), or 
until the effective date of the new entry process for postal shipments 
established by CBP, whichever date occurs first.'' \5\ In turn, 
Proclamation 11012 invoked Section 122 of the Trade Act of 1974, and 
pursuant to Section 122, imposed, for a period of 150 days, a 10 
percent ad valorem surcharge on certain imports.
---------------------------------------------------------------------------

    \5\ The products subject to this interim process are shipments 
of articles that formerly qualified for the de minimis exemption 
under 19 U.S.C. 1321(a)(2)(C), and which are not identified in 50 
U.S.C. 1702(b). A detailed description of this interim process prior 
to E.O. 14388 appears in the Federal Register notice implementing 
E.O. 14324. See 90 FR 42418 (Sept. 2, 2025).
---------------------------------------------------------------------------

    Consistent with the policy objectives encapsulated by these 
Executive Orders, and independently pursuant to CBP's own statutory 
authorities, as discussed in further detail below, and after 
considering the relevant issues and factors and weighing the relevant 
considerations, this rulemaking implements in CBP regulations an 
indefinite suspension of the de minimis administrative exemption under 
19 U.S.C. 1321(a)(2)(C) (hereinafter ``the de minimis administrative 
exemption'' or ``the de minimis exemption'') for merchandise valued at 
$800 or less and imported by one person on one day arriving through the 
international postal network, consistent with 19 U.S.C. 1321(b), to 
protect revenue, prevent unlawful importations, and for further reasons 
discussed in more detail below. This rulemaking does not affect the 
availability of the exemptions for bona fide gifts under 19 U.S.C. 
1321(a)(2)(A) or personal or household articles accompanying travelers 
under 19 U.S.C. 1321(a)(2)(B). Further, this rulemaking establishes a 
new process for merchandise valued at $2,500 or less entering the 
United States through the mail environment, including shipments that 
would previously have been eligible for the de minimis exemption. 
Although this rulemaking is implementing the indefinite suspension of 
the de minimis administrative exemption for merchandise valued at $800 
or less arriving through the international postal network (also 
referred to in this document as mail or postal environment), CBP is 
publishing a concurrent rulemaking announcing the indefinite suspension 
of the de minimis administrative exemption for merchandise valued at 
$800 or less arriving via all modes other than through the 
international postal network.\6\
---------------------------------------------------------------------------

    \6\ Although CBP is issuing this interim final rule concurrently 
with a separate interim final rule addressing related issues under 
19 U.S.C. 1321, CBP views each rule as a distinct regulatory action. 
CBP would have issued this interim final rule even if the other 
interim final rule had not been issued, and CBP intends that this 
interim final rule remain in effect even if the other interim final 
rule is later amended, delayed, or held invalid in whole or in part, 
unless CBP itself changes this rule through subsequent rulemaking.
---------------------------------------------------------------------------

    Specifically, and as discussed in more detail below, this 
rulemaking addresses certain challenges CBP faces in the informal mail 
entry environment related to the de minimis exemption. These challenges 
concern efforts to protect the revenue and to identify violations of 
U.S. customs and trade laws, health and safety requirements, 
intellectual property rights, and consumer protection rules, as well as 
to detect and prevent the entry of illicit drugs such as fentanyl 
(including synthetic drug precursors and related chemicals and related 
manufacturing equipment). To address these challenges, in addition to 
announcing the indefinite suspension of the de minimis exemption for 
merchandise in the postal environment, this rule also makes changes 
from what is currently required under the interim process announced in 
Executive Order 14324, as amended, for goods arriving through the 
international postal network and further specified in CBP's Notice of 
Implementation of the President's Executive Order 14324, Suspending 
Duty-Free De Minimis Treatment for All Countries.\7\

A. Authority

1. The De Minimis Administrative Exemption
    Section 321 of the Tariff Act of 1930 (19 U.S.C. 1321), as amended 
by the Trade Facilitation and Trade Enforcement Act of 2015 (TFTEA), 
Section 901, Public Law 114-125, 130 Stat. 122, authorizes the 
Secretary of the Treasury,\8\ ``in order to avoid expense and 
inconvenience to the Government disproportionate to the amount of 
revenue that would otherwise be collected,'' to provide by regulation 
for administrative exemptions from duty and any tax imposed on or by 
reason of importation for three categories of articles. These 
categories include: bona-fide gifts valued at $100 or less ($200, if 
the gift is from certain island possessions) sent from persons in 
foreign countries to persons in the United States (19 U.S.C. 
1321(a)(2)(A)); certain personal or household articles valued at $200 
or less accompanying persons arriving in the United States (19 U.S.C. 
1321(a)(2)(B)); and other articles when the value of the article is 
$800 or less, referred to here as the de minimis administrative 
exemption (19 U.S.C. 1321(a)(2)(C)). The origin of the de minimis 
exemption was to codify the Government's existing discretionary 
``practice of waiving duties when, in the opinion of local customs 
officials, collecting the duty would be an inefficient use of 
government resources.'' \9\ Though Congress has several times amended 
Section 321, including to adjust the statute's dollar

[[Page 37803]]

amounts, the purpose of Section 321 has remained the same.\10\
---------------------------------------------------------------------------

    \8\ The Secretary of the Treasury has delegated this authority 
to the Secretary of Homeland Security pursuant to the Homeland 
Security Act of 2002 (see Pub. L. 107-296, 116 Stat. 2142) and 
Treasury Order 100-20 (Oct. 30, 2024), available at https://home.treasury.gov/about/general-information/orders-and-directives/treasury-order-100-20.
    \9\ Imports and the Section 321 (De Minimis) Exemption: Origins, 
Evolution, and Use, Cong. Research Serv., R48380 at 5-6 (Jan. 31, 
2025); see also, e.g., Customs Administrative Act of 1938, Public 
Law 75-721, 52 Stat. 1081 (June 25, 1938), ch. 679, Sec.  7.
    \10\ See, e.g., Simplification of Customs Administration: 
Hearings on H.R. 1535 Before the Comm. on Ways and Means House of 
Rep., 82nd Cong., at 19 (1951) (``the purpose'' of this provision 
was ``to avoid waste of customs manpower in determining and 
collecting trivial amounts of money,'' and ``[t]he object of the 
[1953] amendment [was] the same as that of the original section[ ] . 
. . [as it was] necessary in order to minimize the cost of 
administering the customs service''); H.R. Rep. No. 83-760, at 123 
(1953) (noting that Section 321 was ``intended to avoid dissipating 
customs manpower in assessing and collecting duties in trivial 
amounts''); H.R. Rep. No. 103-361, pt. 1, at 144-45 (1993) (changing 
the statutory amount because ``inflation and the substantial 
increases in passenger arrivals and low-value entries'' meant that 
the statutory amounts that were then in place were ``not 
sufficiently high for the statutorily stated goal of limiting 
expense to the Government disproportionate to the revenue that is 
collected''); S. Rep. No. 103-189, at 93 (1993); Customs 
Modernization Act, Title VI of the North American Free Trade 
Agreement Implementation Act, Public Law 103-182, 651, 107 Stat. 
2057, 2209 (1993); Trade Facilitation and Trade Enforcement Act of 
2015, Public Law 114-125, 901, 130 Stat. 122 (2016).
---------------------------------------------------------------------------

    In granting this discretion to admit articles free of duty and of 
any tax imposed by reason of importation, in order to avoid expense and 
inconvenience to the Government disproportionate to the amount of 
revenue that would otherwise be collected, Section 321(a)(2)(C) sets a 
framework for any de minimis exemption that the Secretary of the 
Treasury (Secretary) (and now the Secretary of Homeland Security) 
chooses, in his or her discretion, to implement. In other words, the 
Secretary's authority to implement the administrative exemptions 
authorized under Section 321 is, and has always been, discretionary, 
not mandatory. Nothing in Section 321 requires the Secretary to create 
(or to maintain) a de minimis exemption. Instead, the creation (or the 
maintaining) of the de minimis exemption is in the Secretary's 
discretion.
    Importantly, 19 U.S.C. 1321(b) also authorizes the Secretary to 
promulgate regulations that except certain merchandise from eligibility 
for the administrative exemptions in 19 U.S.C. 1321(a) when the 
Secretary finds that such an exception is consistent with the purpose 
of 19 U.S.C. 1321(a) or is necessary for any reason to protect the 
revenue or to prevent unlawful importations.
    The de minimis exemption is implemented in part 10 of title 19 of 
the Code of Federal Regulations (19 CFR part 10) at 19 CFR 10.151 and 
10.153, and is also referenced in 19 CFR parts 128, 143, and 145 (Mail 
Importations), the general subject of this rulemaking.
2. Entry Procedures
    All merchandise imported into the customs territory of the United 
States is subject to entry and clearance procedures, unless 
specifically excepted. These procedures ensure the proper appraisement, 
valuation, and tariff classification of the merchandise for the purpose 
of collecting the lawful amount of duties owed, as well as compliance 
with all other laws and regulations administered and enforced by CBP. 
Different types of entry procedures are used for the entry and 
clearance of merchandise depending upon its value and other relevant 
criteria.
    Formal entry procedures, established by 19 U.S.C. 1484 and 1485, 
are generally applicable to shipments of merchandise valued in excess 
of $2,500.\11\ Informal entry procedures are authorized by 19 U.S.C. 
1498(a)(1)(A) for shipments of merchandise valued at $2,500 or less, 
and may incorporate formal entry procedures appearing in 19 U.S.C. 1484 
and 1485.\12\ 19 U.S.C. 1498(b). Informal entry regulations are 
generally found in 19 CFR part 143, subpart C. Specific procedures for 
shipments imported by mail, including informal mail entries, are found 
in part 145, Mail Importations (19 CFR part 145). Generally, informal 
entry procedures are less burdensome and complex than formal entry 
procedures. But CBP may require formal entry for any merchandise if 
deemed necessary for purposes of admissibility, revenue protection, or 
the efficient conduct of customs business. 19 CFR 143.22.
---------------------------------------------------------------------------

    \11\ Part 142 of title 19 of the CFR (19 CFR part 142) 
implements 19 U.S.C. 1484, as amended, and prescribes formal entry 
procedures.
    \12\ The Secretary of the Treasury is authorized to ``prescribe 
rules and regulations for the declaration and entry of merchandise 
when the aggregate value of the shipment does not exceed an amount 
specified . . . by regulation, but not more than $2,500.'' See 19 
U.S.C. 1498(a)(1)(A). The Homeland Security Act of 2002 (HSA) 
generally transferred the functions of the U.S. Customs Service from 
the Treasury Department to the Secretary of Homeland Security. See 
Public Law 107-296, 116 Stat. 2142; 6 U.S.C. 203 (``there shall be 
transferred to the Secretary [of Homeland Security] the functions . 
. . of (1) the United States Customs Service of the Department of 
the Treasury, including the functions of the Secretary of the 
Treasury relating thereto''). Nevertheless, pursuant to Section 412 
of the HSA, the Treasury Department retained authority related to 
various customs revenue functions, including those functions found 
in the Tariff Act of 1930, Public Law 71-361, 46 Stat. 590, as 
amended (codified at 19 U.S.C. 1202 et seq.). 6 U.S.C. 212(a)(1), 
(2). But the Secretary of the Treasury may delegate any such 
retained authority at the Secretary's discretion. 6 U.S.C. 
212(a)(1). Consistent with this delegation authority, the Secretary 
of the Treasury issued Treasury Order 100-20 (available at https://home.treasury.gov/about/general-information/orders-and-directives/treasury-order-100-20), delegating the authorities contained in 6 
U.S.C. 212 and 215 to the Secretary of Homeland Security.
---------------------------------------------------------------------------

    Additionally, specific procedures for shipments arriving through 
the international postal network, including merchandise that could have 
previously qualified for the de minimis exemption prior to its 
suspension, are found in part 145, Mail Importations (19 CFR part 145). 
CBP is publishing a separate rulemaking concurrently with this 
rulemaking announcing the indefinite suspension of the de minimis 
administrative exemption for merchandise valued at $800 or less 
arriving via all modes other than through the international postal 
network.

B. De Minimis and the Dangers of the Low-Value Shipment E-Commerce 
Environment

    The Customs Administrative Act of 1938 amended the Tariff Act of 
1930 by adding Section 321, which authorized the original de minimis 
exemption for articles imported by one person on one day which are 
valued at $1 or less, in order to limit the ``expense and 
inconvenience'' of collecting duty when ``disproportionate to the 
amount of such duty.'' \13\ At that time, the amount of duty to be 
collected for these low-value shipments was deemed to be so minimal 
(especially when compared to the costs associated with collecting the 
duties that would have been owed) that ``the purpose of [Section 321 as 
added in 1938 was] to avoid waste of customs manpower in determining 
and collecting trivial amounts of money.'' \14\ Congress subsequently 
raised the value cap for articles eligible for the de minimis exemption 
authorized by Section 321(a)(2)(C), as amended, to $5 in 1978, $200 in 
1993, and most recently, to $800 in 2016.\15\

prepared by the Department of the Treasury and included as part of 
the legislative record for the Customs Simplification Act of 1953

Implementation Act, Public Law 103-182, 107 Stat. 2057, 2209 (1993) 
(raising the daily value cap to $200 and also removing the specific 
authorization to the Secretary of the Treasury to diminish the 
dollar amount of the administrative exemption); Trade Facilitation 
and Trade Enforcement Act of 2015, Public Law 114-125, 130 Stat. 122 
(2016) (raising the daily value cap to $800).
---------------------------------------------------------------------------

    The current regulatory framework for the de minimis exemption was 
promulgated through two final rules in

[[Page 37804]]

1994 and 1995. The 1994 rule provided express consignment operators and 
carriers the right to enter goods into the United States without a 
registered customs broker.\16\ The 1995 rule amended the customs 
regulations to implement the legislative increase of the value cap to 
$200, and to specify the special informal entry procedures applicable 
to qualifying low-value shipments.\17\ In 2016, Section 901(d) of the 
Trade Facilitation and Trade Enforcement Act of 2015 (TFTEA) amended 19 
U.S.C. 1321(a)(2)(C) by increasing the value cap from $200 to $800.\18\ 
CBP published an interim final rule amending the regulations to 
implement the new statutory value cap and to identify certain goods 
excluded from eligibility for the de minimis exemption.\19\ Otherwise, 
CBP has not made any significant changes to the regulatory requirements 
since 1995. In those intervening three decades, however, as discussed 
in more detail below, there have been significant changes in the trade 
environment relating to the de minimis exemption.

    \17\ T.D. 95-31 (60 FR 18983 (Apr. 14, 1995)).
    \18\ Section 901 did not change the administrative exemptions 
for bona-fide gifts and personal or household articles accompanying 
travelers under 19 U.S.C. 1321(a)(2)(A) and (B), respectively.
    \19\ CBP Dec. No. 16-13 (81 FR 58831 (Aug. 26, 2016)).
---------------------------------------------------------------------------

    As noted above, E.O. 14324 suspended duty-free de minimis treatment 
under 19 U.S.C. 1321(a)(2)(C) and established an interim process for 
mail shipments formerly eligible for de minimis. Given the risks of 
evasion of U.S. laws, fraud, and illicit-drug importations that create 
health and safety risks, as well as risks to the revenue described in 
the following sections, CBP is implementing a de minimis suspension for 
all merchandise arriving through the international postal network in 
its regulations pursuant to the authority provided for in 19 U.S.C. 
1321.
    Because these shipments are no longer eligible for the de minimis 
exemption, they are also unable to use the special informal entry 
procedures applicable to articles claiming the de minimis exemption. 
Therefore, as explained in more detail below, these shipments will need 
to use an appropriate method of entry, such as the new postal informal 
entry process announced in this rulemaking, which is limited to 
articles classifiable only in chapters 1-97 of the Harmonized Tariff 
Schedule of the United States (HTSUS). For merchandise arriving through 
the international postal network that is subject to any additional 
duties imposed under chapter 99 of the HTSUS, quota, antidumping or 
countervailing duties (AD/CVD) orders, Partner Government Agency (PGA) 
data requirements,\20\ or merchandise for which duty-free treatment is 
claimed under Chapter 98 of the HTSUS or pursuant to a Free Trade 
Agreement, formal entry is required, see 19 CFR 145.12(a).
---------------------------------------------------------------------------

    \20\ As detailed below, CBP has provided a delayed compliance 
date for the requirement that certain merchandise arriving through 
the international postal network must file formal entry. During the 
delayed compliance period, CBP will permit merchandise subject to 
PGA requirements, merchandise subject to duties under Chapter 98 or 
Chapter 99 of the Harmonized Tariff Schedule of the United States 
(HTSUS), or for which duty-free treatment is claimed under Chapter 
98 of the HTSUS or pursuant to a Free Trade Agreement (see new 19 
CFR 145.12(a)(2)(v)-(vi)) to use the postal informal entry process 
established by this rule. For more information on the compliance 
date, please see Section III. Explanation of Amendments to the CBP 
Regulations.
---------------------------------------------------------------------------

    Although this rule is consistent with and responsive to E.O. 14324 
and related Presidential actions, CBP is herein independently 
exercising its statutory authorities to implement a de minimis 
suspension for merchandise arriving through the international postal 
network. After considering the relevant issues and factors and weighing 
the relevant considerations, CBP has determined that duty-free de 
minimis treatment under 19 U.S.C. 1321(a)(2)(C) is no longer necessary 
for shipments through the international postal network to avoid expense 
and inconvenience to the Government disproportionate to the amount of 
revenue that would otherwise be collected. See 19 U.S.C. 1321(a). 
Further, after considering the relevant issues and factors and weighing 
the relevant considerations, CBP has determined that the suspension of 
duty-free de minimis treatment under 19 U.S.C. 1321(a)(2)(C) is 
consistent with the purpose of 19 U.S.C. 1321(a). See 19 U.S.C. 
1321(b). Moreover, after considering the relevant issues and factors 
and weighing the relevant considerations, CBP has independently 
determined that the suspension of duty-free de minimis treatment under 
19 U.S.C. 1321(a)(2)(C) is necessary to protect the revenue. See 19 
U.S.C. 1321(b). In addition, after considering the relevant issues and 
factors and weighing the relevant considerations, CBP has independently 
determined that the suspension of duty-free de minimis treatment under 
19 U.S.C. 1321(a)(2)(C) is necessary to prevent unlawful importations, 
including unlawful importations of illicit or dangerous goods. See 19 
U.S.C. 1321(b). Finally, after considering the relevant issues and 
factors and weighing the relevant considerations, CBP has determined 
that any of the above reasons--separately, cumulatively, or in any 
combination--justifies the suspension of duty-free de minimis treatment 
under 19 U.S.C. 1321(a)(2)(C).
    In making these determinations, CBP considered the relevant issues 
and factors and weighed the relevant considerations. For example, CBP 
considered any potential reliance interests but determined that the 
reliance interests are either not actually present or are outweighed by 
the benefits of this rule. CBP also considered various alternatives but 
determined that this rule is more reasonable than and preferable to 
potential alternatives. In CBP's judgment, this rule is reasonable, 
consistent with the purpose of 19 U.S.C. 1321(a), necessary to protect 
the revenue, and necessary to prevent unlawful importations.
    CBP is adopting these regulatory measures under its own statutory 
authority and would do so even in the absence of E.O. 14324 or any 
related Executive Orders. Moreover, this rulemaking aligns with U.S. 
Government positions in trade and security negotiations with countries 
regarding policy matters that are squarely within the foreign affairs 
domain. The timing of this rulemaking is linked intimately with the 
United States's overall foreign-affairs and national-security agenda 
and affects relations with foreign countries.
1. Exponential Increase in the Volume of De Minimis Packages
    The continued rise of e-commerce, with the internet empowering 
individuals to easily make international purchases, the increase of the 
value cap for the de minimis exemption to $800 in 2016, and the 
establishment of the Entry Type 86 Test \21\ in which CBP authorized a 
voluntary electronic entry process for qualifying low-value shipments 
in the Automated Commercial Environment (ACE), led to drastic increases 
in the volume of shipments using the $800 de minimis exemption, 
including through the international postal environment. The dramatic 
increase in the volume of de minimis shipments accelerated 
overwhelmingly during the COVID-19 pandemic and never returned to pre-
pandemic levels. During Fiscal Year 2024, over 1.36 billion de minimis 
shipments were processed by CBP, an almost ten-fold increase over the 
139 million de minimis shipments

[[Page 37805]]

processed by CBP in 2015.\22\ Today, the crushing volume of these de 
minimis shipments imposes a significant and costly burden on CBP 
related to identifying violative merchandise and processing the 
shipments.
---------------------------------------------------------------------------

(Sept. 2, 2025).

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

    Despite the staggering volume of trade involved, CBP's current 
regulations generally require minimal data for entry of shipments 
claiming the de minimis administrative exemption, and no entry is 
prepared for shipments claiming de minimis in the postal environment. 
The risks associated with merchandise that would have previously 
qualified for the de minimis exemption are even further exacerbated in 
the mail environment. Prior to its suspension, de minimis shipments 
sent via mail were processed initially at one of the U.S. Postal 
Service's (USPS) International Service Centers (ISCs) that sort 
international mail, before being transferred to a CBP facility for 
further examination. Under the current regulatory framework for 
informal entry of merchandise arriving by mail, there is a burdensome 
and manual process for CBP to verify the information necessary for the 
shipment to be deemed admissible and properly entered in accordance 
with all applicable requirements, such as verifying origin and value to 
ensure duties are accurately collected. Pursuant to 19 CFR 
145.12(b)(1), subject to exceptions, a CBP officer must manually 
prepare a mail entry form for a shipment valued at $2,500 or less, and 
the recipient will pay the duties, taxes, and fees owed. Payment is 
generally tendered at the local post office prior to the recipient 
taking possession of the shipment.
    In addition to the time-intensive and costly manual process of 
preparing an entry and collecting duties for informally entered mail 
articles, the high volume and the lack of advance entry information to 
aid in risk assessment and targeting creates substantial problems for 
CBP. CBP also lacks advance information regarding the volume of 
shipments arriving, preventing CBP from effectively allocating 
resources to aid in the processing of mail shipments.
    As noted above, E.O. 14324 resulted in the implementation of an 
interim entry process for low-value mail shipments valued at $2,500 or 
less, including shipments formerly eligible for the de minimis 
exemption. This process did not require CBP to prepare a manual entry 
for those mail shipments, but did mandate duty collection that 
necessitates manual auditing by CBP to ensure proper duty remittance. 
Pursuant to section 2(b) of E.O. 14324, as revised by E.O. 14388, the 
interim process is applicable to mail shipments until such time as CBP 
establishes a new entry process and implementing regulations published 
in the Federal Register take effect.
    Under the Executive Order's interim process as specified by the CBP 
notice, qualified third parties transmit entry data and duties owed to 
CBP. The foreign post office would receive the package from the 
shipper, collect the required information and duties, and transmit 
relevant information and duties owed to the qualified third party. The 
qualified third party would then transmit the following information to 
CBP via email in the form of an Excel spreadsheet:

Carrier
Flight Number
Tracking Number (generated by the foreign post operator)
Arrival Port
Arrival Date
Duty Rate
Country of Origin
Value
Total Duty Owed

    The spreadsheet is required to be transmitted to CBP on the 7th day 
of the month following the arrival of the postal shipment. At the same 
time, the qualified third party would transmit payment for duties owed 
for all shipments arriving the prior month, via Pay.gov. For example, 
for a package that arrived on April 15th, the spreadsheet and payment 
would be due no later than May 7th. Qualified third parties 
transmitting data to CBP are required to have a basic importation and 
entry bond, consistent with 19 CFR 113.62.
    Although this interim process was critical to address the urgent 
issues leading to the emergency declarations detailed in E.O. 14324, 
concerns regarding minimal shipment data and the need for manual 
verification by CBP remain. As explained in more detail in the economic 
analysis section below, the volume of merchandise imported by mail has 
decreased \23\ since the Executive Order's effective date, but the 
overall burden on CBP to assess admissibility of the merchandise and 
collect the relevant duties continues to present challenges.
---------------------------------------------------------------------------

    \23\ There has been an estimated two-thirds reduction in mail 
shipments following the global suspension of the de minimis 
exemption in E.O. 14324.
---------------------------------------------------------------------------

2. Attempted Unlawful Importations
    There is an apparent perception amongst transnational criminal 
organizations and other bad actors that low-value shipments, including 
those through the international postal environment, are less likely to 
be interdicted due to the sheer volume of entries and because these 
shipments are generally not subject to the more extensive formal entry 
procedures. This has resulted in attempts to enter illicit and 
dangerous goods, such as firearms, counterfeit merchandise, illicit 
fentanyl, and other illicit drugs, by claiming the de minimis 
exemption.\24\
---------------------------------------------------------------------------

    \24\ See, e.g., E.O. 14324, 90 FR at 37776-77 (``For example, 
many shippers go to great lengths to evade law enforcement and hide 
illicit substances in imports that go through international 
commerce. These shippers conceal the true contents of shipments sent 
to the United States through deceptive shipping practices. Some of 
the techniques employed by these shippers to conceal the true 
contents of the shipments, the identity of the distributors, and the 
country of origin of the imports include the use of re-shippers in 
the United States, false invoices, fraudulent postage, and deceptive 
packaging. The risks of evasion, deception, and illicit-drug 
importation are particularly high for low-value articles that have 
been eligible for duty-free de minimis treatment.''). For more 
information regarding the national emergency declarations, see 90 FR 
42418 (Sept. 2, 2025) discussing, inter alia, E.O. 14193 of February 
1, 2025 (Imposing Duties To Address the Flow of Illicit Drugs Across 
Our Northern Border), E.O. 14194 of February 1, 2025 (Imposing 
Duties To Address the Situation at Our Southern Border), and E.O. 
14195 of February 1, 2025 (Imposing Duties To Address the Synthetic 
Opioid Supply Chain in the People's Republic of China).
---------------------------------------------------------------------------

    As noted above, the overwhelming volume of low-value shipments, 
including in the postal environment, makes it more challenging for CBP 
to conduct targeting for purposes of identifying violations of U.S. 
customs and trade laws, health and safety requirements, intellectual 
property rights, and consumer protection rules, as well as preventing 
illicit drugs, such as fentanyl (including synthetic drug precursors 
and related chemicals and related manufacturing equipment) from 
entering the country. Moreover, the fact that many consumers ordering 
goods online that were shipped through the international postal network 
are not familiar with the customs and trade laws increases the danger 
that an item they are purchasing may not comply with U.S. health and 
safety standards or pose other risks. Taken together, if not addressed, 
the enforcement challenges in the current environment have the capacity 
to put American consumers' well-being and lives at risk.
3. Significant Uncollected Duties Endangering the Revenue
    Because of the significant burdens that de minimis valued 
merchandise imposes on CBP relating to targeting and processing, 
allowing for the de minimis exemption to remain in place for 
merchandise arriving through the

[[Page 37806]]

international postal network is no longer consistent with the purpose 
of 19 U.S.C. 1321(a), which is to avoid a cost and inconvenience to the 
government that is outweighed by the duties that would be collected. To 
put it plainly, despite collecting no revenue, the burden of work 
imposed on CBP related to the de minimis exemption was growing with 
each passing year until the exemption was suspended.
    Moreover, advances in technology have facilitated the electronic 
filing of an entry along with the automation of data verification and 
duty collection. As a result, where an electronic entry is filed for 
dutiable merchandise, the cost to and burden on CBP from collecting 
duties is negligible, particularly when compared to the burden and 
amount of duties that would otherwise be owed but for the de minimis 
exemption. Additionally, there have been significant improvements in 
CBP's automation regarding the targeting, verification, and processing 
of entry or related data, which removed a significant time burden that 
was part of the original justification for establishing the de minimis 
exemption.
    Today, the outdated and burdensome tasks, involving CBP employees 
having to manually review documents and process money or paper checks 
to collect duties, stand ready to be replaced by fully electronic 
processes. These newer processes minimize the cost to CBP to assess and 
collect duty payments, enforce compliance with applicable PGA 
requirements, and determine admissibility. Technological advances, 
including expanded use of Pay.gov, have significantly reduced the 
burden on CBP personnel pertaining to general duty collection and 
enforcement.\25\
---------------------------------------------------------------------------

    \25\ For example, CBP recently announced Pay.gov as being 
available to pay bills at the importer's convenience. For more 
information, see https://www.cbp.gov/trade/priority-issues/revenue/bill-payments.
---------------------------------------------------------------------------

    Moreover, the revenue forgone due to the de minimis exemption has 
steadily increased, as even low-value merchandise would otherwise be 
subject to additional duties pursuant to trade actions addressing 
discriminatory trade practices and threats to national security and 
domestic industries.\26\ In addition, given CBP's challenges in the de 
minimis enforcement environment, the volume of shipments that claimed 
the de minimis exemption but did not actually qualify resulted in 
significant lost revenue. Therefore, the cost to and burden on CBP to 
collect the duties owed, given advances in technology, pale in 
comparison to the vast aggregate amount of duties uncollected due to 
the de minimis exemption, which endangers the revenue.
---------------------------------------------------------------------------

    \26\ For example, additional duties imposed pursuant to Section 
232 of the Trade Expansion Act of 1962, Section 201 of the Trade Act 
of 1974, and Section 301 of the Trade Act of 1974. See 90 FR 6852 
(Jan. 21, 2025).
---------------------------------------------------------------------------

    Accordingly, in addition to CBP implementing in the regulations the 
indefinite suspension of the de minimis exemption pursuant to its 
authority in 19 U.S.C. 1321 for merchandise arriving through the 
international postal network, as discussed in more detail below, CBP is 
implementing a new postal informal entry process to better address 
unlawful and potentially dangerous importations, and the risks to the 
revenue of the United States, arising from de minimis packages sent 
through the international postal network.\27\
---------------------------------------------------------------------------

    \27\ As noted elsewhere, CBP is also publishing a concurrent 
rulemaking regarding the suspension of the de minimis exemption for 
merchandise arriving via all modes other than through the 
international postal network.
---------------------------------------------------------------------------

4. January 2025 Notices of Proposed Rulemaking and Other Potential 
Alternatives
    In January 2025, CBP published two notices of proposed rulemaking 
that proposed changes to the entry process for low-value shipments. The 
first of these, the ``Entry of Low-Value Shipments'' (ELVS) proposed 
rule, proposed new ``enhanced'' and ``basic'' entry processes and 
associated data requirements for shipments qualifying for and seeking 
the benefit of the de minimis duty exemption authorized under 19 U.S.C. 
1321(a)(2)(C) and 19 CFR 10.151 (90 FR 3048, Jan. 14, 2025). The 
second, the ``Trade and National Security Actions and Low-Value 
Shipments'' (TranSALS) proposed rule, proposed to make merchandise 
subject to specified Sections 232, 201, and 301 actions ineligible for 
the administrative exemption and to require 10-digit HTSUS 
classification for shipments entered under both the basic and enhanced 
processes (90 FR 6852, Jan. 21, 2025).
    But CBP proposed these two rulemakings under very different 
circumstances. Since that time, additional legal and factual 
developments, including E.O. 14324, as revised, subsequent national 
emergency declarations, enactment of legislation terminating the de 
minimis exemption effective July 1, 2027,\28\ and further experience 
with the interim mail process, have demonstrated that these proposed 
rulemakings are not the appropriate course of action at this time and 
do not adequately address revenue and public safety risks associated 
with low-value shipments to the United States.
---------------------------------------------------------------------------

    \28\ One Big Beautiful Bill Act, Public Law 119-21, Section 
70531(b)(3), 139 Stat. 72, 283 (2025).
---------------------------------------------------------------------------

    As further discussed below, although this rulemaking represents a 
different approach from those proposed in ELVS and TranSALS, ELVS and 
TranSALS demonstrate the path CBP has taken in its attempts to get 
control of the overwhelming volume of low-value shipments, as well as 
the associated risks discussed throughout this document. While the ELVS 
proposed rule was intended to assist CBP in acquiring additional data 
regarding low-value shipments, the TranSALS proposed rule was designed 
to limit the availability of the de minimis exemption in certain 
scenarios. Neither of the rules went far enough to address the current 
issues CBP faces in the de minimis and low-value shipment environment, 
particularly with respect to the postal environment. Unlawful 
importation concerns exist for all imports that could qualify for the 
de minimis exemption. Further, limited exceptions to the de minimis 
exemption would raise circumvention or evasion concerns. Lastly, the 
sheer volume of shipments claiming the de minimis exemption, including 
shipments sent through the international postal network, combined with 
the technological advances CBP has implemented in recent years, means 
that allowing the exemption is no longer consistent with the purpose 
stated in Section 321(a); that is, the administrative burden of 
collecting the duties no longer outweighs the revenue to be collected 
for low-value shipments.
    Accordingly, considering its past efforts and the changed 
landscape, CBP has determined that it is necessary to move forward with 
the indefinite suspension of the de minimis exemption for merchandise 
arriving through the international postal network, under CBP's own 
authorities. As described throughout this preamble, the indefinite 
suspension of the de minimis exemption for goods valued at $800 or less 
arriving through the international postal network will help CBP address 
the risks to the revenue and public safety consistent with long-
standing and recent developments, including the policy objectives of 
this Administration.
    CBP has considered other alternatives and determined that at this 
time, this rule is still more reasonable than and preferable to 
potential alternatives. For example, CBP has considered excepting from 
the de minimis exemption some low-value imports but not other low-value 
imports, as in the TranSALS

[[Page 37807]]

proposed rule discussed above.\29\ But unlawful importation concerns 
exist for all low-value imports that could qualify for the de minimis 
exemption. And in general, the expense and inconvenience of imports 
under the de minimis exemption exist for all such imports; a limited 
suspension of the de minimis exemption would not resolve the imbalance 
of the expense and inconvenience of administering the exemption vis-
[agrave]-vis the potential revenue collection. A limited exception to 
the suspension of the de minimis exemption also raises circumvention or 
evasion concerns that are obviated by applying the suspension to all 
shipments. So a limited suspension of only certain low-value imports is 
not as consistent with the purpose of 19 U.S.C. 1321(a) as this rule, 
and would not as effectively protect the revenue or prevent unlawful 
importations. In CBP's judgment, this rule is more reasonable than and 
preferable to this alternative approach.
---------------------------------------------------------------------------

    \29\ This rule does not suspend the exemptions for bona fide 
gifts under 19 U.S.C. 1321(a)(2)(A) or personal or household 
articles accompanying travelers under 19 U.S.C. 1321(a)(2)(B). The 
lower volume and lower value threshold of these exemptions raise 
different issues. Bona fide gifts and personal or household articles 
accompanying travelers do not raise the same unlawful-importation or 
revenue concerns or at least do not do so anywhere near the same 
extent. In CBP's judgment, it is not necessary at this time to 
suspend the exemptions for bona fide gifts under 19 U.S.C. 
1321(a)(2)(A) or personal or household articles accompanying 
travelers under 19 U.S.C. 1321(a)(2)(B).
---------------------------------------------------------------------------

    CBP has considered the option of requiring additional information 
while not indefinitely suspending the de minimis exemption, as proposed 
in the ELVS proposed rule discussed above.\30\
---------------------------------------------------------------------------

    \30\ In this interim final rule, CBP is also modifying entry 
requirements for shipments through the international postal 
environment to ensure the accurate collection of duties, taxes, and 
fees, and to better enable CBP to prevent unlawful importations. In 
CBP's judgment, these modifications, in tandem with the indefinite 
suspension of the de minimis exemption, are necessary to protect the 
revenue and to prevent unlawful importations. Still, as noted above, 
although CBP is issuing this interim final rule concurrently with a 
separate interim final rule addressing related issues under 19 
U.S.C. 1321 for the non-postal environment, CBP views each rule as a 
distinct regulatory action. CBP would have issued this interim final 
rule even if the other interim final rule had not been issued, and 
CBP intends that this interim final rule remain in effect even if 
the other interim final rule is later amended, delayed, or held 
invalid in whole or in part, unless CBP itself changes this rule 
through subsequent rulemaking.
---------------------------------------------------------------------------

    But merely requiring additional entry requirements without the 
suspension of de minimis does not adequately address the revenue and 
unlawful-importation concerns. Indeed, even if increased information 
could as effectively address unlawful importation, increased 
information does not protect the revenue and, in fact, exacerbates the 
expense and inconvenience to the Government, making such expenses and 
inconvenience even more disproportionate to the amount of revenue that 
would otherwise be collected. So this alternative is not as consistent 
with the purpose of 19 U.S.C. 1321(a) as this rule and does not as 
effectively protect the revenue or prevent unlawful importations as 
this rule.
    Finally, CBP has considered other alternatives, including a 
combination of the above alternatives, but CBP has determined that at 
this time, this rule's approach is more consistent with the applicable 
statutory provisions and more effectively protects the revenue and 
prevents unlawful importations than potential alternatives. In CBP's 
judgment and based on CBP's experience, this rule is better than 
alternative approaches and is the most reasonable approach for 
addressing the relevant issues.

C. Addressing the Dangers of the De Minimis Administrative Exemption in 
the Postal Environment

1. Suspension of the De Minimis Administrative Exemption for 
Merchandise Arriving Through the International Postal Network
    As discussed above, the de minimis exemption is discretionary under 
Section 321. Moreover, 19 U.S.C. 1321(b) authorizes the Secretary to 
promulgate regulations that except merchandise from eligibility for the 
administrative exemptions otherwise authorized by 19 U.S.C. 1321(a) 
when such exceptions are consistent with the purpose of 19 U.S.C. 
1321(a), or necessary to protect the revenue or to prevent unlawful 
importations. Pursuant to this statutory authority, and consistent with 
E.O. 14324, as revised by E.O. 14388, CBP is implementing a regulatory 
suspension of the exemption authorized in 19 U.S.C. 1321(a)(2)(C).\31\ 
Accordingly, this rule amends 19 CFR 145.31 to announce the indefinite 
suspension of the de minimis exemption at 19 U.S.C. 1321(a)(2)(C) for 
merchandise arriving through the international postal network. Any 
subsequent modification or revocation of this suspension will be 
announced in the Federal Register.
---------------------------------------------------------------------------

    \31\ Again, CBP issues this rule independently of the Executive 
Orders.
---------------------------------------------------------------------------

    No other duty exemptions specified in 19 U.S.C. 1321(a)(2) are 
affected by this rulemaking. Specifically, the requirements for 
entering shipments exempt from duty under 19 U.S.C. 1321(a)(2)(A), 
bona-fide gifts valued at $100 or less ($200, if the gift is from 
certain island possessions) sent from persons in foreign countries to 
persons in the United States, and under 19 U.S.C. 1321(a)(2)(B), 
certain personal or household articles valued at $200 or less 
accompanying persons arriving in the United States, remain unchanged. 
As noted elsewhere in this document, CBP is also publishing a 
concurrent rulemaking regarding the suspension of the de minimis 
exemption for merchandise arriving via all modes other than through the 
international postal network.
2. New Informal Mail Procedures
    Considering the issues discussed above and the shifting of mail 
volumes formerly eligible for the de minimis exemption to other 
informal entry processes, CBP has determined it is necessary to amend 
the regulations to include a new informal entry process for mail 
shipments valued at $2,500 or less that will replace the interim 
process applied pursuant to Executive Order 14324, as amended. The 
modified entry process and requirements will allow CBP to collect all 
applicable duties, taxes, and other fees (rather than a subset); better 
ensure the accuracy of the collection of applicable duties, taxes, and 
other fees; better enable CBP to police undervaluation, evasion, and 
fraud; and better prevent unlawful importation through the 
international postal environment. Accordingly, CBP is amending 19 CFR 
145.31(b), as well as making other conforming changes throughout part 
145, to provide for this new postal informal entry process. Notably, 
the requirements for this new process are related to the entry and 
release of merchandise imported into the United States through the 
postal network and are distinct from, and in addition to, Universal 
Postal Union (UPU) requirements.
a. Eligible Shipments of Merchandise
    Except during the delayed compliance period described below, the 
new postal informal entry process provided for in this rulemaking is 
available only to shipments of merchandise valued at $2,500 or less, 
that are sent to the United States via mail, and are classifiable only 
in Harmonized Tariff Schedule of the United States (HTSUS) chapters 1-
97. Merchandise subject to quota, antidumping or countervailing duties 
(AD/CVD) orders, any duties imposed under chapters 98 and 99 of the 
HTSUS, import and entry-related Partner Government Agency (PGA) 
requirements, or merchandise for which duty-free treatment is claimed 
under Chapter 98 of the HTSUS or pursuant to

[[Page 37808]]

a Free Trade Agreement, is ineligible to use the new informal postal 
entry process. Such merchandise must instead use formal entry 
procedures (see 19 CFR 145.12(a)).
b. Eligible Parties
    The process for filing under this new postal informal entry process 
is limited to parties with the right to make entry under 19 CFR 
143.26(a), that is, an owner or purchaser of the merchandise being 
mailed to the United States, or a licensed customs broker appropriately 
designated by the owner, purchaser, or consignee. See 19 CFR 143.26(a).
c. Bonding Requirements
    The Secretary of Homeland Security and the Commissioner of CBP have 
broad legal authority to require bonds or other security ``by 
regulation or specific instruction'' when necessary to protect the 
revenue of the United States or to assure compliance with any law, 
regulation, or instruction that CBP is authorized to enforce. 19 U.S.C. 
1623(a); \32\ 19 CFR 113.1. The Secretary and the Commissioner also 
have the authority to prescribe the conditions and form of the bond, 
the manner in which the bond may be filed, and the amount of the bond. 
19 U.S.C. 1623(b); 19 CFR 113.2. In 19 CFR part 113, CBP has 
promulgated regulations exercising this authority, detailing 
requirements for the execution and filing of bonds required by Chapter 
I of title 19 of the Code of Federal Regulations. Subpart G of 19 CFR 
part 113 enumerates the terms and conditions for regulatory bonds 
required by CBP. The terms and conditions for the Basic Importation and 
Entry Bond are found in 19 CFR 113.62.
---------------------------------------------------------------------------

    \32\ The Homeland Security Act of 2002 (HSA) generally 
transferred the functions of the U.S. Customs Service from the 
Treasury Department to the Secretary of Homeland Security. See 
Public Law 107-296, 116 Stat. 2142; 6 U.S.C. 203 (``there shall be 
transferred to the Secretary [of Homeland Security] the functions . 
. . of (1) the United States Customs Service of the Department of 
the Treasury, including the functions of the Secretary of the 
Treasury relating thereto''). Nevertheless, pursuant to Section 412 
of the HSA, the Treasury Department retained authority related to 
various customs revenue functions, including those functions found 
in the Tariff Act of 1930, Public Law 71-361, 46 Stat. 590, as 
amended (codified at 19 U.S.C. 1202 et seq.). 6 U.S.C. 212(a)(1), 
(2). But the Secretary of the Treasury may delegate any such 
retained authority at the Secretary's discretion. 6 U.S.C. 
212(a)(1). Consistent with this delegation authority, the Secretary 
of the Treasury issued Treasury Order 100-20 (available at https://home.treasury.gov/about/general-information/orders-and-directives/treasury-order-100-20), delegating the authorities contained in 6 
U.S.C. 212 and 215 to the Secretary of Homeland Security.
---------------------------------------------------------------------------

    To protect the revenue, and ensure compliance with applicable laws 
and regulations, CBP is requiring that the party filing a postal 
informal entry have a bond to secure the transaction. Accordingly, CBP 
is amending the regulations for informal mail entries by adding a new 
regulation at 19 CFR 145.15 to clarify that the party making entry must 
obtain a basic importation and entry bond (either a single transaction 
bond (STB) or a continuous bond), with the conditions found in 19 CFR 
113.62, sufficient to secure the entries using the new mail process for 
informal entries provided for in this rulemaking.
    This bonding requirement secures the revenue to be collected from 
such imported merchandise. A basic importation and entry bond also 
secures redelivery of merchandise, e.g., when additional information is 
necessary to determine admissibility, and obligates an importer of 
record to correct non-compliance with an applicable law or regulation 
pertaining to admissibility, thereby ensuring the safety and security 
of American consumers. Importantly, as noted above, qualified third 
parties participating in the current interim process for mail shipments 
are already required to have a bond.
d. New Regulatory Process and Data Requirements
    CBP is establishing in the regulations a new process for informal 
mail shipments. This new regulatory process improves upon the interim 
process established pursuant to Executive Order 14324, as amended. 
Under the new regulatory process, the filer will be responsible for 
obtaining and transmitting the following required information to CBP 
via email in the form of an Excel spreadsheet:

Filer Code
Bond Number
Description of Merchandise
Country of Origin of Merchandise
All Applicable 10-digit HTSUS Classification(s)
Quantity/Weight (conditional and required ONLY if using a specific 
duty rate)
Duty Rate
Value
Total Duty Owed
Carrier
Flight/Conveyance Number
Tracking Number (generated by the foreign post operator)
Arrival Port
Arrival Date

    The Excel spreadsheet must be transmitted to [email protected] no 
later than the 7th day of the month following the package's arrival. 
Pursuant to 19 U.S.C. 1315(a)(1), the duty rate for a mail article is 
based on the ``rate or rates in effect when the preparation of the 
entry is completed[.]'' Because CBP is no longer preparing the entry, 
the regulations are being amended to reflect that the preparation of 
the informal mail entry is completed upon the filing of the entry in 
proper form, meaning in accordance with 19 CFR 141.68(h) and all other 
applicable requirements, including the timely transmittal of the Excel 
spreadsheet. Payment must be transmitted via Pay.gov no later than the 
7th day of the month following the arrival of the shipment. For 
example, for a package that arrived on April 15th, the spreadsheet and 
payment would be due no later than May 7th.
e. No CBP Officer Manual Preparation of Forms
    As part of the transition to this new postal informal entry process 
for mail shipments, CBP officers will no longer manually prepare entry 
forms for such shipments, and duties will not be collected upon 
delivery of such shipments to addressees. Accordingly, CBP is amending 
19 CFR 145.12(b)(1) to remove the relevant language providing for 
manual preparation of the entry forms.
3. Reliance Interests
    It is well established that there is no protectable legal interest 
in importing merchandise, let alone doing so free of duty.\33\ Indeed, 
importers lack any constitutional right to the maintenance of an 
existing rate of duty. But to the extent importers may have reliance 
interests tethered to the regulatory status quo, CBP has determined 
that they in no event outweigh the United States's interest in 
indefinitely suspending the de minimis exemption.
---------------------------------------------------------------------------

    \33\ See, e.g., Int'l Custom Prods., Inc. v. United States, 791 
F.3d 1329, 1337 (Fed. Cir. 2015) (``As we noted, `the Constitution 
does not provide a right to import merchandise under a particular 
classification or rate of duty,' . . . or even afford `a protectable 
interest to engage in international trade.''' (quoting, 
respectively, A Classic Time v. United States, 123 F.3d 1475, 1476 
(Fed. Cir. 1997), and Am. Ass'n of Exporters & Importers-Textile & 
Apparel Grp. v. United States, 751 F.2d 1239, 1250 (Fed. Cir. 
1985))); The Abby Dodge v. United States, 223 U.S. 166, 176-77 
(1912) (``[N]o one can be said to have a vested right to carry on 
foreign commerce with the United States.''); Norwegian Nitrogen 
Prods. Co. v. United States, 288 U.S. 294, 318 (1933) (``No one has 
a legal right to the maintenance of an existing rate or duty.'').
---------------------------------------------------------------------------

    Whatever reliance interest related to the de minimis exemption 
importers may have, the interest is not weighty. The existence of the 
de minimis administrative exemption has always been at the discretion 
of the Secretary under Section 321 and in any event, has always been 
subject to an express statutory authorization for reduction or 
modification through regulatory action. Plus, the de minimis exemption 
has been suspended since at least August

[[Page 37809]]

29, 2025.\34\ Moreover, the One Big Beautiful Bill Act, which was 
enacted on July 4, 2025, terminated the de minimis exemption effective 
July 1, 2027.\35\ Thus, any reliance interests from prior regulatory 
policy are significantly minimized by the fact that the de minimis 
exemption under 19 U.S.C. 1321(a)(2)(C) was always subject to change 
under Section 321, is currently suspended, has been suspended for 
months, and will in 2027 be permanently terminated pursuant to a recent 
statute. Though CBP is cognizant that importers may have some minimal 
residual reliance interests in the de minimis exemption, CBP has 
determined that such reliance interests are outweighed by the benefits 
of eliminating the de minimis exemption. Indeed, CBP has determined at 
this time that any of the above reasons--separately, cumulatively, or 
in any combination--outweighs any reliance interests created by a prior 
policy allowing the de minimis exemption for low-value imports through 
the international postal environment and any benefits from a prior 
policy allowing the de minimis exemption for low-value imports through 
the international postal environment.
---------------------------------------------------------------------------

    \34\ See E.O. 14324, 90 FR 37775 (suspending duty-free de 
minimis treatment for low-value imports of all countries since 
August 29, 2025); E.O. 14256, 90 FR 14899 (suspending duty-free de 
minimis treatment for low-value imports from the People's Republic 
of China since May 2, 2025). To be sure, due to practical 
limitations, only certain duties were collected for low-value 
imports sent through the international postal environment under the 
current suspension of de minimis treatment under IEEPA. But 
importers were on notice that CBP would issue new processes to 
address these practical limitations, greatly reducing (if not 
eliminating) any reliance interest. See Suspending Duty-Free De 
Minimis Treatment for All Countries, 90 FR 37775, 37777 (allowing 
low-value postal shipments to pass without entry and only limited 
duties ``until such time as CBP establishes a new entry process and 
publishes that process in the Federal Register.'').

70531(b), 139 Stat. 72, 283 (2025).

III. Explanation of Amendments to the CBP Regulations

Amendments to Part 145

    CBP is amending part 145, in accordance with the new requirements 
described above. Specifically, CBP is making the following changes:
    CBP is amending 19 CFR 145.12 in multiple places. CBP is amending 
19 CFR 145.12(a) by removing the requirement that formal entries be 
made at the customhouse, and further enumerating the circumstances 
where a formal mail entry is required. Additionally, as mentioned 
above, CBP is providing a narrow and short-term delayed compliance 
window regarding the enforcement of 19 CFR 145.12(a)(2)(v)-(vi), during 
which CBP will permit merchandise subject to PGA requirements, 
merchandise subject to duties under Chapter 98 or Chapter 99 of the 
Harmonized Tariff Schedule of the United States (HTSUS), or for which 
duty-free treatment is claimed under Chapter 98 of the HTSUS or 
pursuant to a Free Trade Agreement to use the postal informal entry 
process established by this rule. Accordingly, until the date specified 
in the DATES section of this document for 19 CFR 145.12(a)(2)(v)-(vi), 
mail shipments valued at $2,500 or less and subject to PGA data 
requirements, merchandise subject to duties under Chapter 98 or Chapter 
99 of the HTSUS, or for which duty-free treatment is claimed under 
Chapter 98 of the HTSUS or pursuant to a Free Trade Agreement, may use 
the new postal informal entry procedures provided for in this 
rulemaking. CBP is providing this flexible and narrow delayed 
compliance window in order to provide the trade with sufficient time to 
adjust to the new requirements and in consideration of the business 
process changes that may be necessary to achieve full compliance. 
Concurrently with this rulemaking, CBP is also announcing a test of a 
new voluntary electronic mail process for shipments valued at $2,500 or 
less, known as the Entry Type 13 test, which will provide an optional 
alternative to filing formal entry in those cases. The opening of the 
Entry Type 13 test will coincide with the end of the delayed compliance 
window. Accordingly, at the end of the delayed compliance window for 
those specified shipments, filers may choose to utilize formal entry 
procedures (in accordance with 19 CFR 145.12(a)(2)(v)-(vi)) or 
participate in the Entry Type 13 test.
    CBP is amending 19 CFR 145.12(b) in multiple places to provide for 
the new postal process for informal mail entries discussed throughout 
this rulemaking, as well as removing the requirement that a CBP Officer 
prepare manual entries.
    CBP is adding a new Section 145.15 (19 CFR 145.15) to state that an 
informally entered mail shipment entered using the new postal informal 
entry process provided for in 19 CFR 145.12(b) will not be released 
from CBP custody, and the entry will not be accepted, unless a single 
transaction or continuous bond, containing the bond conditions set 
forth in Sec.  113.62 of this chapter, executed by an approved 
corporate surety, or secured by cash deposits as provided for in Sec.  
113.40 of this chapter, has been transmitted to CBP pursuant to part 
113.
    CBP is amending 19 CFR 145.31 to provide for the indefinite 
suspension of the de minimis exemption for merchandise arriving through 
the international postal network. CBP's determinations and amendments 
in this interim final rule are intended to operate independently of one 
another. Each provision, including the suspension of the de minimis 
administrative exemption for merchandise arriving through the 
international postal network, the new postal informal entry process and 
its associated data requirements, and the bonding requirements for 
informal mail entries, is supported by the record and authorities 
described in this preamble, and CBP would have adopted each provision 
even in the absence of any other provision in this interim final rule. 
Accordingly, if any provision, or the application of any provision to a 
particular person or circumstance, is held unlawful or unenforceable, 
CBP intends that the remaining provisions, and their application to 
other persons or circumstances, continue in effect to the maximum 
extent permitted by law. For example, if a particular data element or 
procedural requirement in the postal informal entry process were set 
aside by a court, CBP would continue to implement the suspension of the 
de minimis administrative exemption for postal shipments, as well as 
the remaining aspects of the postal informal entry process and the 
bonding requirements.

IV. Statutory and Regulatory Requirements

A. Administrative Procedure Act

    The Administrative Procedure Act (APA), 5 U.S.C. 551 et seq., 
generally requires agencies to publish a notice of proposed rulemaking 
in the Federal Register and provide interested persons the opportunity 
to submit comments prior to issuing a final rule. Notice and comment, 
however, is not required here because this rule involves a foreign 
affairs function of the United States and because CBP finds good cause, 
as notice and public comment here is impracticable and contrary to the 
public interest. 5 U.S.C. 553(a)(1), (b)(B).
    First, the requirements of the APA do not apply to the extent that 
the rulemaking involves a foreign affairs function of the United 
States. 5 U.S.C. 553(a)(1). Because this rule involves a foreign 
affairs function of the United States, notice and comment is not 
required.
    Proceeding before notice and comment will prevent definitely 
undesirable international

[[Page 37810]]

consequences.\36\ It will allow the U.S. Government to more promptly 
address sensitive foreign-policy and national-security matters that 
affect relations with foreign governments. Proceeding before notice and 
comment will reduce the risk that a delay in acting would undermine the 
strength of U.S. Government positions in trade and security 
negotiations with foreign countries, which implicate this rulemaking. 
For example, the United States is currently in negotiations regarding 
imports of certain articles and derivative articles that the President 
has found under Section 232 are being imported into the United States 
in such quantities or under such circumstances as to threaten to impair 
the national security of the United States.\37\ This rule directly 
implicates the collection of duties for such imports and how such 
imports enter the United States. In addition, the United States is 
negotiating trade and security agreements with foreign governments, as 
well as issuing joint statements on framework trade and security 
agreements.\38\ Again, this rule could implicate the collection of 
duties and the terms of entry for imports that are at issue in these 
negotiations and framework trade and security agreements.
---------------------------------------------------------------------------

    \36\ See, e.g., Am. Ass'n of Exporters & Importers-Textile & 
Apparel Grp. v. United States, 751 F.2d 1239, 1249 (Fed. Cir. 1985) 
(``The purpose of the exemption was to allow more cautious and 
sensitive consideration of those matters which `so affect relations 
with other Governments that, for example, public rule-making 
provisions would provoke definitely undesirable international 
consequences.' '').
    \37\ See, e.g., Proclamation 10976 of September 29, 2025, 
Adjusting Imports of Timber, Lumber, and Their Derivative Products, 
90 FR 48127 (Oct. 6, 2025) (imposing tariffs under Section 232 on 
certain imports of wood products and directing senior officials to 
pursue negotiations of agreements regarding the national security 
threat posed by imports of wood products); Proclamation 11002 of 
January 14, 2026, Adjusting Imports of Semiconductors, Semiconductor 
Manufacturing Equipment, and Their Derivative Products Into the 
United States, 91 FR 2443 (Jan. 20, 2026) (imposing tariffs under 
Section 232 on certain semiconductors and directing senior officials 
to pursue negotiations of agreements regarding the national security 
threat posed by imports of semiconductors, semiconductor 
manufacturing equipment, and their derivative products); 
Proclamation 11020 of April 2, 2026, Adjusting Imports of 
Pharmaceuticals and Pharmaceutical Ingredients Into the United 
States, 91 FR 18183 (Apr. 9, 2026) (similar with respect to imports 
of pharmaceuticals and pharmaceutical ingredients).
    \38\ See, e.g., Executive Order 14346 of September 5, 2025, 
Modifying the Scope of Reciprocal Tariffs and Establishing 
Procedures for Implementing Trade and Security Agreements, 90 FR 
43737 (Sept. 10, 2025); General Terms for the United States of 
America and the United Kingdom of Great Britain and Northern Ireland 
Economic Prosperity Deal, White House (May 8, 2025), https://www.whitehouse.gov/briefings-statements/2025/05/general-terms-for-the-united-states-of-america-and-the-united-kingdom-of-great-britain-and-northern-ireland-economic-prosperity-deal/; Joint 
Statement on a United States-European Union Framework on an 
Agreement on Reciprocal, Fair, and Balance Trade, White House (Aug. 
21, 2025), https://www.whitehouse.gov/briefings-statements/2025/08/joint-statement-on-a-united-states-european-union-framework-on-an-agreement-on-reciprocal-fair-and-balanced-trade/; United States-
India Joint Statement, White House (Feb. 6, 2026), https://www.whitehouse.gov/briefings-statements/2026/02/united-states-india-joint-statement/.
---------------------------------------------------------------------------

    Moreover, proceeding before notice and comment will reduce the risk 
of impairing relations with other countries through advance public 
discussion of whether certain imports from certain countries are a 
potential danger to the national security and revenue collection of the 
United States. It will also reduce the risk of the United States 
suffering retaliation from foreign countries for the action in this 
interim final rule before the rule takes effect.\39\
---------------------------------------------------------------------------

    \39\ See, e.g., Executive Order 14259 of April 8, 2025, 
Amendment to Reciprocal Tariffs and Updated Duties as Applied to 
Low-Value Imports From the People's Republic of China, 90 FR 15509 
(Apr. 14, 2025); Executive Order 14266 of April 9, 2025, Modifying 
Reciprocal Tariff Rates to Reflect Trading Partner Retaliation and 
Alignment, 90 FR 15625 (Apr. 15, 2025).
---------------------------------------------------------------------------

    In short, advance public notice and comment here would hamper the 
President and his Administration's ability to conduct foreign policy 
regarding matters that are squarely within the foreign-affairs domain. 
The timing and substance of this rulemaking are linked intimately with 
the United States's overall foreign-affairs and national-security 
agenda and relations with foreign countries.\40\
---------------------------------------------------------------------------

    \40\ CBP has determined that the 30-day delayed effective date 
for the new postal informal entry process provided for in this 
rulemaking strikes the appropriate balance between sufficient 
preparation time without undue interruption in implementation. The 
30-day delayed effective date is designed to provide adequate time 
to affected parties to prepare for the changes set forth in this 
rule while not unduly delaying the implementation of the critical 
measures needed to target illicit and dangerous goods, protect the 
national security of the United States, and protect the revenue of 
the United States.
---------------------------------------------------------------------------

    In addition, proceeding before notice and comment may prevent the 
flooding of low-value merchandise into the United States, including the 
illegal importation or smuggling of illicit drugs and other harmful 
unlawful imports in these low-value shipments. Before completion of 
advance notice and comment, manufacturers and importers may have a 
significant incentive to flood as much low-value merchandise as 
possible into the United States before this rule takes effect, thereby 
frustrating the purpose of the rule.\41\ The flooding concern is 
particularly acute here, where current implementation of the suspension 
of the de minimis exemption under IEEPA does not practically enable 
full collection of applicable duties for shipments through the 
international postal environment, while this rule would enable full 
collection of applicable duties for shipments through the international 
postal environment.
---------------------------------------------------------------------------

    \41\ See Am. Ass'n of Exporters & Importers-Textile & Apparel 
Grp., 751 F.2d at 1249 (concluding that the foreign affairs function 
exception applied in part because ``prior announcement of CITA's 
intention to impose stricter quotas pending consultations creates an 
incentive for foreign interests and American importers to increase 
artificially the amount of trade in textiles prior to a final 
administrative determination. American importers would want to 
increase inventories in the face of the prospect that foreign 
supplies could drop below current levels. Foreign manufacturers 
would have a great incentive to dump (in the literal and technical 
senses of the word) as much merchandise as possible into the United 
States, since the quotas CITA imposes are based on the levels of 
trade in the preceding months. The expansion in American imports 
between the date of notice and date of the final rule would 
exacerbate the market disruption which led CITA to act in the first 
place.'' (citation modified)).
---------------------------------------------------------------------------

    The President's actions under IEEPA confirm that this interim final 
rule falls under the foreign affairs function exception.\42\ In E.O. 
14324, as modified by E.O. 14388, discussed in more detail above, the 
President took several actions ``to deal with the unusual and 
extraordinary threats, which have their source in whole or substantial 
part outside the United States, to the national security, foreign 
policy, and economy of the United States.'' As noted in E.O. 14324 and 
related Executive Orders, these threats include the public health 
crisis caused by fentanyl and other illicit drugs, and the activities 
of chemical precursor suppliers, money launderers, and other 
transnational criminal organizations. To address these threats, E.O. 
14324 suspended the de minimis exemption, mandated certain filing 
requirements for shipments that qualified for the de minimis exemption 
prior to the effective date of the order, and established an interim 
process and new duty rate for covered products sent to the United 
States through the international postal network. The President also 
recognized that to more efficiently and effectively implement the 
suspension of the de minimis exemption under IEEPA, CBP would need to 
supplement the interim process that the Executive Order, as amended, 
established for international mail shipments with a new entry process 
that enables collection of all

[[Page 37811]]

applicable duties for the postal environment.\43\
---------------------------------------------------------------------------

    \42\ See, e.g., United States v. Quinn, 401 F. Supp. 2d 80, 94, 
n.12 (D.D.C. 2005) (``IEEPA-based regulations are likely to be 
exempt from the notice-and-comment requirements of the 
Administrative Procedure Act as relating to the `foreign affairs 
function of the United States,' within the meaning of 5 U.S.C. 
553(a)(1).'').
    \43\ See E.O. 14324, 90 FR at 37778 (``until such time as CBP 
establishes a new entry process and publishes that process in the 
Federal Register''); E.O. 14388, 91 FR at 9434 (``until the 
effective date for the new entry process for postal shipments 
established by CBP and published in the Federal Register'').
---------------------------------------------------------------------------

    Though this interim final rule is under CBP's independent statutory 
authority, it is grounded in, and addresses, the same foreign unusual 
and extraordinary threats on which the President's suspension of the de 
minimis exemption under IEEPA was based. Specifically, as discussed 
above, this interim final rule implements the regulatory suspension of 
the de minimis exemption for merchandise arriving through the 
international postal network under CBP's own statutory authority, and 
expands upon the very measures taken in E.O. 14324, as amended, to 
address those foreign threats (e.g., establishing an additional postal 
process for informal entries for merchandise entering through the mail 
environment). Therefore, this interim final rule involves foreign 
affairs functions of the United States.
    Second, the APA provides an exception to advance notice and comment 
requirements ``when the agency for good cause finds (and incorporates 
the finding and a brief statement of reasons therefor in the rules 
issued) that notice and public comment thereon are impracticable, 
unnecessary, or contrary to the public interest.'' 5 U.S.C. 553(b)(B).
    CBP finds that good cause exists to issue this rule as an interim 
final rule, with provisions for post-promulgation public comments, 
under the APA's good cause exception. Delaying the publication of this 
interim final rule for purposes of providing public notice and comment 
would be impracticable and contrary to the public interest. CBP finds 
that due and timely execution of its functions would be significantly 
impeded by advance notice and comment.\44\ CBP finds that immediate 
implementation of this rule directly affects public safety and 
addresses imminent hazards to persons or property within the United 
States. CBP finds that delay for advance notice and comment would 
create a significant threat of serious damage to important public 
interests, would harm the public welfare, and would tend to defeat the 
purpose of the action in this interim final rule.\45\ In CBP's judgment 
and based on CBP's experience, the urgency here is one that does not 
always exist in the trade context.
---------------------------------------------------------------------------

    \44\ See, e.g., Tom C. Clark, Attorney General's Manual on the 
Administrative Procedure Act, at 30 (1947) (``In general, it may be 
said that a situation is `impracticable' when an agency finds that 
due and timely execution of its functions would be impeded by the 
notice otherwise required in section 4 (a).''); S. Doc. No. 248, 
79th Cong., 2d Sess. 200 (1946); Jifry v. FAA, 370 F.3d 1174, 1179 
(D.C. Cir. 2004); NRDC v. Nat'l Highway Traffic Safety Admin., 894 
F.3d 95, 114 (2d Cir. 2018).
    \45\ See, e.g., Tom C. Clark, Attorney General's Manual on the 
Administrative Procedure Act, at 30-31 (1947).
---------------------------------------------------------------------------

    As an initial matter, as explained above, further delaying the 
interim final rule's effectiveness for notice and comment will have 
significant foreign affairs implications and undesirable international 
consequences. Further, as explained above, it may also result in the 
flooding of low value shipments into the United States that undermines 
this rule and the foreign policy, national security, and economy of the 
United States. And as noted above, this interim final rule addresses 
the unusual and extraordinary foreign threats acknowledged in E.O. 
14324 and other related Executive Orders, consistent with the 
Administration's direction and foreign policy priorities. As discussed 
above, and for the reasons cited above, as well as those cited in E.O. 
14324 and E.O. 14388, to address the unusual and extraordinary threats 
to the national security, foreign policy, and economy of the United 
States, this rule establishes a new process for informal mail entries, 
to replace the temporary process set forth in E.O. 14324, as amended, 
including additional data elements to aid in targeting and processing, 
thereby protecting the revenue of the United States, and most 
importantly, protecting the health and safety of the public.
    Moreover, given the critical public health and safety implications 
of continued shipments of illegal opioids into the United States in the 
de minimis mail environment, to delay the implementation of this rule 
would be impracticable and contrary to the public interest. With this 
rulemaking, CBP is addressing various issues threatening public safety 
and posing risks to the revenue in the de minimis informal mail 
environment, while facilitating lawful importers in complying with 
their statutory and regulatory responsibilities.\46\

(citing the Attorney General's Manual for the proposition that the

notice would defeat the purpose of the rule).
---------------------------------------------------------------------------

    In the mail environment, under current regulations at 19 CFR 
145.31, de minimis shipments would (in the absence of the Executive 
Orders) pass free of duty and tax without preparing an entry, such that 
the processes applicable to mail shipments eligible for the de minimis 
exemption provide insufficient and untimely data for CBP to handle the 
extreme volume of low-value shipments while also addressing the influx 
of illicit shipments, including dangerous and harmful drugs, being 
shipped to the United States in the mail environment. Though the 
interim process for mail shipments implemented pursuant to Executive 
Order 14324, as amended, provides a pathway for the entry of low-value 
mail shipments, it was intended to be temporary until CBP establishes a 
new entry process, and did not fully address the information gaps in 
the mail environment required to fully collect duties on shipments 
formerly eligible for the de minimis exemption.\47\ This interim final 
rule provides important additional entry processes to ensure the full 
collection of information and duties for postal shipments beyond those 
in E.O. 14324, as amended, which will reduce unlawful importation and 
protect the revenue. The new postal informal entry process provided for 
in this rulemaking is needed to ensure that CBP has more information 
about shipments arriving in the mail environment, to interdict 
dangerous and illegal shipments, including those with fentanyl and 
other illicit drugs, chemical precursors, and other dangerous goods. 
The new postal process will also allow lawful importers to enter 
merchandise in a safer and more secure mail environment. Moreover, this 
rule requires goods subject to the requirements of PGAs to be entered 
under formal entry procedures. This allows the Government to ensure 
compliance with the health and safety requirements of PGAs under the 
more robust formal entry process, to prevent dangerous and illegal 
merchandise from entering the country.
---------------------------------------------------------------------------

    \47\ Indeed, the applicable Executive Orders anticipated that 
CBP would need to continue to establish additional entry processes 
for postal environment, including to collect all applicable duties 
in the postal environment. See E.O. 14324, 90 FR at 37778 (``until 
such time as CBP establishes a new entry process and publishes that 
process in the Federal Register''); E.O. 14388, 91 FR at 9434 
(``until the effective date for the new entry process for postal 
shipments established by CBP and published in the Federal 
Register'').
---------------------------------------------------------------------------

    In short, delaying implementation of these requirements, for 
purposes of notice-and-comment proceedings, would delay action that 
immediately addresses risks to the public's health and safety. A delay 
would also result in multiple burdens for the Government.

[[Page 37812]]

As discussed above, the threat to the revenue posed by the sheer volume 
of shipments claiming the de minimis exemption has defeated the 
underlying purpose of the de minimis exemption. That is, there was no 
revenue being collected, yet the burden of processing the vast numbers 
of de minimis mail shipments continued to grow. The suspension of de 
minimis for mail, in conjunction with the establishment of a new postal 
process allowing for the full collection of duties, is essential to 
protect the revenue of the United States. Moreover, under this rule, 
goods subject to quota, AD/CVD, or additional duties imposed under 
Chapters 98 and 99 of the HTSUS, or for which a claim for duty-free 
treatment is made under Chapter 98 or pursuant to a Free Trade 
Agreement, are required to enter under formal entry procedures. This 
ensures that CBP has adequate data and processes to collect the revenue 
in these special circumstances. Accordingly, it would be impracticable 
and contrary to the public interest to further delay implementation of 
these requirements, which will provide CBP with more data to help 
protect the American public from dangerous and illegal goods entering 
from abroad, and to protect the revenue of the United States.
    CBP is publishing this rulemaking with a request for comments to 
allow the public to weigh in on the regulatory changes. Additionally, 
CBP is publishing this rulemaking with a delayed effective date for the 
requirements regarding the new postal informal entry process in order 
to give the lawful importing community time to modify the relevant 
processes. However, the substantial additional delays in implementation 
that would result from advance notice and comment or a more protracted 
delayed effective date would risk frustrating the Administration's 
chosen and appropriate means of addressing the very issues targeted by 
this rulemaking. Such delays would also create a degree of uncertainty 
that would undermine the credibility and effectiveness of the United 
States's emergency trade and counter-narcotics measures and could 
incentivize attempts to send more illicit shipments into the country 
before this rulemaking enters into effect. Nevertheless, CBP is 
voluntarily soliciting public comments on this interim final rule and 
will consider all timely submitted comments in determining whether and 
how to revise the rule in a subsequent final rulemaking.
    In sum, for the reasons discussed, this rule is exempt from the 
prior public notice and comment requirements of the APA under both the 
foreign affairs exception and the good cause exception. For more 
information and statistics on the volume of attempted illicit 
shipments, including dangerous and harmful drugs, and informal entry 
shipments generally, please see the analysis below.

B. Executive Orders 12866, 13563, and 14192

    Executive Orders 12866 (Regulatory Planning and Review) and 13563 
(Improving Regulation and Regulatory Review) direct agencies to assess 
the costs and benefits of available regulatory alternatives and, if 
regulation is necessary, to select regulatory approaches that maximize 
net benefits. Executive Order 13563 emphasizes the importance of 
quantifying both costs and benefits, of reducing costs, of harmonizing 
rules, and of promoting flexibility. Executive Order 14192 (Unleashing 
Prosperity Through Deregulation) directs agencies to significantly 
reduce the private expenditures required to comply with Federal 
regulations and provides that ``any new incremental costs associated 
with new regulations shall, to the extent permitted by law, be offset 
by the elimination of existing costs associated with at least 10 prior 
regulations.''
    This rule has been designated a ``significant regulatory action'' 
that is economically significant, under section 3(f)(1) of Executive 
Order 12866. Accordingly, the rule has been reviewed by the Office of 
Management and Budget. Pursuant to section 5(a) of Executive Order 
14192, the requirements of that Executive Order do not apply to 
regulations issued with respect to foreign affairs-related functions of 
the United States. As discussed above, this interim final rule is 
issued with respect to foreign affairs-related functions of the United 
States Government. Accordingly, this rule is exempt from the 
requirements of Executive Order 14192. CBP discusses both quantified 
and qualitative effects of the rule in the analysis below. The 
estimated quantified net annualized costs of the rule equal $169,794 at 
a 7% discount rate or $172,980 at a 3% discount rate. The rule will 
also result in an increase in tariff revenue, discussed in the 
Transfers section. The estimated annualized tariff revenue that would 
result from the rule is $166,130,323 at a 7% discount rate or 
$163,007,696 at a 3% discount rate. Table 1 shows an accounting 
statement for the effects of the rule.

Background

    The Customs Administrative Act of 1938 amended the Tariff Act of 
1930 by adding Section 321, which authorized a general de minimis 
exemption for imported merchandise valued at $1 or less in order to 
limit the ``expense and inconvenience'' of collecting duty when 
``disproportionate to the amount of such duty.'' \48\ The duties 
potentially owed for such shipments were considered de minimis because 
the revenue associated with collecting the duties that would have been 
owed would not have covered the cost of collecting the duties.
---------------------------------------------------------------------------

    \48\ Customs Administrative Act of 1938, Public Law 75-721, 52 
Stat. 1077, 1081 (1938).
---------------------------------------------------------------------------

    The current regulatory framework for the de minimis exemption was 
promulgated through a final rule in 1995, which, among other things, 
amended the customs regulations to implement the legislative increase 
of the exemption to $200 and specify the special informal entry 
procedures applicable to qualifying low-value shipments.\49\ Such 
shipments were not subject to the same formal customs entry procedures 
and data requirements as higher-value shipments entering the United 
States.\50\
---------------------------------------------------------------------------

    \49\ 60 FR 18983 (Apr. 14, 1995). See 19 U.S.C. 1498(a)(1)(A) 
(authorizing regulations to prescribe special rules for the 
declaration and entry of merchandise when the aggregate value of the 
shipment does not exceed an amount specified by the Secretary by 
regulation, but not more than $2,500).
    \50\ See 60 FR 18983.
---------------------------------------------------------------------------

    In 2016, TFTEA increased the administrative exemption from $200 to 
$800.\51\ CBP published an interim final rule amending the regulations 
to implement the new statutory amount and to specify certain goods 
excluded from the administrative exemption.\52\ Otherwise, CBP has not 
made any significant changes to the regulatory requirements since 1995. 
In the intervening three decades, however, there have been significant 
changes in the trade environment relating to the de minimis exemption.
---------------------------------------------------------------------------

    \51\ Section 901 did not change the administrative exemptions 
for bona-fide gifts and personal or household articles accompanying 
travelers under 19 U.S.C. 1321(a)(2)(A) and (B), respectively.

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

    The continued rise of e-commerce, with the internet empowering 
individuals to easily make international purchases, the increase of the 
value cap for the de minimis exemption to $800 in 2016, and the trade's 
usage of the Entry Type 86 Test \53\ in which CBP authorized a 
voluntary new electronic entry process for qualifying low-value 
shipments in ACE, have led to drastic increases in the volume of 
shipments using the $800 de minimis exemption (and low-value informal 
entries more generally, i.e., shipments valued at $2,500 or less). The 
dramatic increase in the volume of de minimis shipments (and low-value 
shipments generally) accelerated overwhelmingly during the COVID-19 
pandemic and has shown no signs of returning to pre-pandemic levels. 
During Fiscal Year 2024, over 1.36 billion de minimis shipments were 
processed by CBP, an almost ten-fold increase over the 139 million de 
minimis shipments processed by CBP in 2015.\54\ Today, the crushing 
volume of these shipments imposes a significant and costly burden on 
CBP relating to targeting and processing the shipments.

    On July 4, 2025, the President signed into law the ``One Big 
Beautiful Bill'' Act, which, among other things, enacted the 
termination of the de minimis exemption effective July 1, 2027.\55\ On 
July 30, 2025, the President signed E.O. 14324 (Suspending Duty-Free De 
Minimis Treatment For All Countries), which discussed multiple declared 
national emergencies and announced that the President determined that 
it was necessary and appropriate to suspend duty-free de minimis 
treatment under 19 U.S.C. 1321(a)(2)(C) for most imports, to deal with 
the continuing unusual and extraordinary threats, which have their 
source in whole or substantial part outside the United States, to the 
national security, foreign policy, and economy of the United 
States.\56\

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

    Prior to E.O. 14324, mail shipments claiming the administrative 
exemption under 19 U.S.C. 1321(a)(2)(C) did not have an entry prepared 
and were not required to pay duties. E.O. 14324, which suspended de 
minimis treatment for most importations, established an interim mail 
duty process and mail shipments previously eligible for duty-free de 
minimis treatment were subject to duty payments for the first time. 
Unlike for other entry methods, the Executive Order permitted two duty 
calculation methodologies for shipments sent through the international 
postal network that were no longer eligible for de minimis

[[Page 37814]]

treatment--an ad valorem duty methodology and a specific duty 
methodology assessed on each package. The duties were allowed to be 
paid by carriers or qualified parties. So far, only qualified parties 
have submitted the international mail duty worksheets needed to 
calculate duties, and all qualified parties have chosen to pay using 
the ad valorem method.
    On February 20, 2026, the President signed E.O. 14388 (Continuing 
the Suspension of Duty-Free De Minimis Treatment For All Countries), 
which, among other things, continued the suspension of duty-free de 
minimis treatment under 19 U.S.C. 1321(a)(2)(C), including for 
shipments sent through the international postal network, and confirmed 
that CBP should continue to collect applicable duties, taxes, fees, 
exactions, and charges on such shipments. Section 3 of E.O. 14324, as 
revised by E.O. 14388, established an interim process and new duty 
rates for covered products sent to the United States through the 
international postal network and directed that the duty rate ``shall be 
assessed until the expiration date of the temporary import surcharge 
established by Proclamation 11012 of February 20, 2026 (Imposing a 
Temporary Import Surcharge to Address Fundamental International Payment 
Problems), or until the effective date of the new entry process for 
postal shipments established by CBP, whichever date occurs first.'' 
\57\ In turn, Proclamation 11012 invoked Section 122 of the Trade Act 
of 1974, and pursuant to Section 122, imposed, for a period of up to 
150 days, a 10 percent ad valorem surcharge on certain imports to 
address fundamental international payments problems and to deal with 
large and serious United States balance-of-payments deficits.
---------------------------------------------------------------------------

    \57\ The covered products subject to this interim process are 
shipments of articles that formerly qualified for the de minimis 
exemption under 19 U.S.C. 1321(a)(2)(C), and which are not 
identified in 50 U.S.C. 1702(b). A detailed description of this 
interim process prior to E.O. 14388 appears in the Federal Register 
notice implementing E.O. 14324. See 90 FR 42418 (Sept. 2, 2025).
---------------------------------------------------------------------------

    Although the de minimis exemption has been suspended for both 
postal and non-postal environments, there is a disparity between postal 
and non-postal modes in terms of the information submitted and duties 
applied. Low-value non-postal shipments that would have claimed the de 
minimis exemption are now generally entered through entry type 11 
(ET11), and CBP applies all applicable duties, taxes, and fees to those 
shipments. Low-value postal shipments that would have claimed the de 
minimis exemption are now entered through the interim postal process, 
and, unlike ET11, the postal process only applies the simple 10% ad 
valorem duty mentioned above. To declare the value of the imports and 
the duties owed to CBP, qualified parties must submit a monthly 
International Mail Duty Worksheet (IMDW) that details the value of each 
shipment and the corresponding duty owed.\58\ Furthermore, even if CBP 
wanted to apply other duties to postal entries, the interim postal 
process does not currently collect enough data on entries to be able to 
apply all the duties to which ET11 entries are subject. Namely, postal 
shipments are not required to provide HTSUS classifications, which 
determine the appropriate duty rate in many cases. Accordingly, with 
this rule, CBP is requiring the relevant information needed to properly 
collect duties owed.
---------------------------------------------------------------------------

    \58\ Even if a qualified party has many clients, the party 
submits only one worksheet per month.
---------------------------------------------------------------------------

Purpose of Rule
    CBP had been overwhelmed by the number of low-value shipments being 
brought into the country with little or no accurate and reliable data 
which CBP could use to properly assess admissibility, duty 
requirements, and PGA requirements. By 2025, the administrative 
exemption had become a substantial risk to the revenue and the health 
and welfare of U.S. residents, and, through E.O. 14324, the 
administrative exemption was suspended for most importations in 2025. 
This rule makes several changes to address various issues that remain 
unresolved by the current interim mail process.
Suspension of the De Minimis Exemption for Postal Shipments
    Due to the high volume of de minimis shipments and the lack of 
reliable data for admissibility determinations, administering the de 
minimis exemption had become a significant time burden to CBP. CBP 
officers needed to manually review data submitted and, often, 
physically inspect the package to know what was in the shipment. At the 
same time, advances in technology that facilitate automation and 
electronic filing of entry and collection of duties reduced the burden 
of collecting duties on shipments. Combined, the increased burden of 
administering the de minimis exemption and the reduced burden of 
collecting duties made the current environment no longer consistent 
with the purposes of 19 U.S.C. 1321(a), which is to avoid a cost and 
inconvenience to the government that is outweighed by the possible 
duties that would be collected. E.O. 14324 suspended use of the 
administrative exemption for most importations in 2025, and E.O. 14388 
continued the suspension of the administrative exemption. For the 
reasons described in this rule and to establish new procedures for 
informal mail entry made necessary by the suspension of the 
administrative exemption, CBP is also amending the regulations under 
its own authorities to suspend the use of the Section 321(a)(2)(C) 
administrative exemption. As a result, the administrative exemption 
will no longer be available for formerly de minimis postal shipments 
pursuant to Section 321(a)(2)(C). Shipments must instead go through the 
new postal informal entry process or through a different entry type, 
such as formal entry. With the suspension of de minimis, importers of 
postal shipments will need to provide additional data for these 
shipments compared to the old de minimis processes.
    While CBP is exercising its own authority to suspend de minimis for 
postal shipments, E.O. 14324 has been in effect since August 29, 2025, 
and the statutory repeal of the basis for de minimis will take effect 
starting on July 1, 2027. This rule does not, in practice, change the 
existing suspension of de minimis for postal shipments; rather it 
matches the existing suspension to a regulatory suspension implemented 
in this rule, providing better clarity. CBP considers the effects of 
the suspension of de minimis for postal shipments to belong to the 
Executive Orders (from August 29, 2025 until July 1, 2027) and the 
statutory repeal of the basis for the de minimis exemption (from July 
1, 2027 on).
    Should the Executive Order be amended or removed prior to the 
statutory repeal of de minimis, CBP's regulatory suspension would 
remain in effect and take on the effects of the suspension of de 
minimis for postal shipments that would have otherwise belonged to the 
Executive Orders between the effective date of the change in the 
Executive Orders and the statutory change. Once the statutory repeal of 
de minimis is effective, the effects of the de minimis suspension 
belong to the statutory change and not this rule.
New Postal Informal Entry Process
    CBP has determined that it is necessary to update the temporary, 
interim postal process established by the Executive Order 14324, as 
amended by E.O. 14388 (with the new process to

[[Page 37815]]

be called the new postal informal entry process) to reduce the 
disparity between postal and non-postal informal shipments. Filers will 
now need to submit on their international mail duty worksheets, the 
filer code, bond number, all applicable 10-digit HTSUS classifications 
for each shipment,\59\ and a description of the merchandise. If the 
applicable duty is dependent on the quantity or weight of the 
merchandise, then that information must be submitted as well. These 
additional data elements will allow CBP to apply the duties to postal 
shipments that are already being collected from non-postal ET11 
entries, improving parity between postal and non-postal shipments. 
Because the new postal informal entry process will require the filer to 
provide more detailed information, CBP is requiring that the filer be a 
party with the right to make entry, including a duly-authorized, 
licensed customs broker. The filer code is being added as a required 
data element so that CBP can validate that the broker is licensed. As 
with the baseline interim postal process, the filer will submit the 
information to CBP through a monthly IMDW, which will cover all the 
shipments handled by the filer that month. This method of data 
submission differs from the method of other entry types, for which a 
separate entry form is submitted for each shipment.
---------------------------------------------------------------------------

    \59\ Some goods, like watches, may require multiple HTSUS 
classifications, corresponding to the different duties that all 
apply to that good.
---------------------------------------------------------------------------

    As discussed later in this analysis, CBP estimates that the new 
postal informal entry process will lead to an increase in duties of 
more than $100 million per year. Therefore, CBP is protecting the 
revenue of the U.S. Government by requiring proper classification of 
merchandise and subjecting all informal mail entries to the appropriate 
duties, unless excepted pursuant to another exception.
Baseline and Regulatory Alternative Scenarios
    This regulatory impact analysis estimates the net effects of the 
rule by comparing the baseline scenario with the regulatory alternative 
scenario. In the baseline, the President already suspended the use of 
the de minimis administrative exemption for most imports, including 
postal shipments, and postal shipments continue to be entered through 
the interim mail process that was put in place in 2025, pursuant to 
E.O. 14324, as amended by E.O. 14388. Additionally, the ``One Big 
Beautiful Bill'' Act, as enacted, eliminates the de minimis exemption 
effective July 1, 2027. This rule considers the effects of deviations 
from the baseline. In the regulatory alternative scenario, the interim 
postal process is updated to require additional data elements so that 
CBP may apply non-Section 122 duties to informal postal shipments. The 
benefits and costs of the rule are the benefits and costs of changing 
from the baseline to the regulatory alternative scenario. Because the 
rule takes effect midway through 2026, this analysis considers the 
effects of the rule over a 10-year regulatory period from mid-2026 to 
mid-2036. CBP deals with the shortened first and last year of the 
analysis by cutting the estimates of most costs and benefits in 2026 
and 2036 by half.
Projected Entry Counts
    In this section, CBP presents its projections for postal de minimis 
entry counts from 2026-2036, which CBP uses for its calculations in the 
Transfers section. Although the rule could affect import volumes, CBP 
assumes, for the purposes of calculating the effect of the rule on 
government revenue, that annual entry counts would be the same in the 
regulatory scenario as in the baseline scenario.\60\ This simplifying 
assumption allows CBP to calculate total tax revenue and other costs 
using the same projected entry counts used in the baseline. However, 
the rule will result in certain higher duties and shipping costs for 
postal shipments, and these changes will likely cause total imports to 
fall by some amount. As a result of this decrease in imports, the total 
increase in government revenue will likely be lower than in the 
analysis, which assumes the rule will have no effect on the quantity of 
imports. The fall in imports will also lead to a deadweight loss, 
increasing the total cost of the rule to society beyond CBP's cost 
estimates in the analysis. CBP discusses these limitations of the 
analysis further below. Table 1 displays the annual entry counts for 
postal entries from FY 2021 to FY 2024. Over this time period, the 
compound annual growth rate (CAGR) for postal de minimis entries was -
11.63%.
---------------------------------------------------------------------------

    \60\ The rule could lead to some entries shifting from postal to 
non-postal modes, but such a shift would not affect our quantified 
cost estimates. After all, the increase in duties would be the same 
whether a postal shipment uses the new postal informal entry process 
or switches to ET11 as a result of the rule.

    In 2025, the imposition of new duties, the suspension of the de 
minimis exemption for most imports, and the creation of an interim mail 
process led to a large decrease in import volume. The de minimis 
exemption was suspended for most imported products of all countries 
effective August 29, 2025. Therefore, CBP uses entry counts from the 
following three months, September through November of 2025, to estimate 
the inflow of entries under the current status quo. From September 1 to 
November 30, 7,254,980 postal entries arrived in the United States. At 
that rate, 29,099,645 postal shipments would arrive annually. These 
numbers are shown in Table 2.

Source: Obtained from Office of Trade (OT) on December 4, 2025. The
  projected annual counts equal the counts from September 1 to November
  30, 2025, multiplied by 365/91.

    Compared to the 2024 entry counts, the figures in Table 2 show that 
the suspension of de minimis led to a fall in postal shipments. As de 
minimis will remain suspended (in either scenario), CBP does not expect 
postal volumes to return to pre-2025 levels. Moreover, now that the 
interim mail process is being updated, postal shipments could face even 
higher duties and data requirements than they did under the baseline 
interim mail process, making it even less likely that postal entry 
counts will rebound. To project postal entry counts during the 
regulatory period, 2026-2036, CBP applies the CAGR from 2021-2024 to 
the projected annual count in Table 2. These projections are shown in 
Table 3.

Costs
    The rule will result in costs due to increased information 
requirements, the exclusion of certain goods from the new postal 
informal entry process, deadweight loss from higher duties, and the 
possibility of temporary hiatuses of postal shipments.
CBP
    Although more data will be submitted under the new postal informal 
entry process than under the interim process provided for in Section 3 
of E.O. 14324, as revised by E.O. 14388, CBP does not expect that 
handling this extra data will be more work on CBP's part, other than 
requiring some modifications to the current database to accommodate 
additional data elements.\61\ The cost to CBP of making those 
modifications is negligible.\62\

Filers
    The new postal informal entry process will require filers to submit 
additional data elements, namely the filer code, bond number, all 
applicable 10-digit HTSUS classifications, and a description of the 
merchandise. Moreover, if the duty depends on the quantity or weight of 
the merchandise, then that data will also be required. Filers will 
submit these additional data elements to CBP on the monthly IMDW. 
Brokers may file a monthly IMDW that covers all shipments for all of 
the broker's clients that month. CBP estimates that the updated IMDW 
will take 6 hours to complete each month, which is 4 hours more than 
the time burden in the baseline.\63\ In both the baseline and in the 
regulatory scenario, CBP estimates that there will be 100 filers who 
submit the IMDW once a month. The total time burden of the IMDW will 
therefore increase by 400 hours per month, or 4,800 hours per year. CBP 
assumes that, under the rule, most if not all IMDWs will be submitted 
by brokers. Applying an average broker wage of $36.57, the added annual 
time burden equals $175,536 per year.\64\ CBP estimates that the cost 
in 2026 and in 2036 will be $87,768 (=$175,536/2) because the period of 
analysis starts in the mid-2026 and ends in mid-2036. Although CBP is 
including this cost in the filer subsection, importers may bear some of 
the burden, as they may have to start giving brokers more information 
about the shipments so that the brokers can classify the goods. 
Moreover, brokers could shift some of the monetary burden onto 
importers by charging higher fees.

Importers
Exclusion of Non-Broker Qualified Parties From Submitting an IMDW
    Because the new version of the IMDW will require product 
classifications, submission of the IMDW will now be considered customs 
business. Therefore, if not the owner or purchaser, only licensed 
customs brokers will be allowed to submit the IMDW. Currently, about 
half of qualified parties are brokers. Importers and foreign postal 
operators (FPOs) that are working with non-broker qualified parties 
will need to find a licensed customs broker. Based on conversations 
with non-broker qualified parties representing a majority of IMDW 
submissions to CBP, these parties typically have an existing 
relationship with a broker, sometimes where the broker is part of the 
company or a subsidiary, so many of the importers will not be affected 
by this provision. This change will be an inconvenience to the 
importers and FPOs who do not already have a relationship with a 
broker, as it will take time to find a broker and perhaps for the FPO 
to sign a contract with that new party. Of course, the exclusion of 
non-broker qualified parties from submitting IMDWs will also hurt said 
qualified parties, but we count this effect as a pure transfer from 
non-brokers to brokers and discuss it in the Transfers section below.
Exclusion of Certain Goods From the New Postal Informal Entry Process
    Under the rule, importers will not be allowed to import goods 
subject to Section 201, Section 232, or Section 301 duties, or goods 
subject to AD/CVD orders, or goods subject to PGA data requirements 
through the new postal informal entry process. Technically, goods 
subject to PGA data requirements were already excluded from the interim 
postal process in the baseline, but enforcement of this rule could 
improve as a result of the product classification data that CBP will be 
requiring. To continue importing these goods excluded from the new 
postal informal entry process, importers will need to switch to another 
entry type. These other entry types require the importer to submit more 
data, and they also require the broker to do more work, which could 
entail significant broker fees. Importers who are not using the new 
postal informal entry process will have to provide data for CBP Forms 
3461 and 7501 for entry and entry summary, respectively. The time 
burden for CBP Form 3461 is 10 minutes,\65\ and that of CBP Form 7501 
is 5 minutes.\66\ Our

[[Page 37817]]

estimate for the average hourly wage of importers is $36.57.\67\ The 
average costs of the time burdens for submitting CBP Forms 3461 and 
7501 are therefore $6.10 and $3.05. Furthermore, these entry forms have 
to be submitted much sooner than the IMDW, which is not due until 7 
days after the end of the current month. Due to the present lack of 
product classification data in the postal environment, CBP does not 
know what share of postal entries will no longer be eligible for the 
new postal informal entry process. Therefore, CBP cannot estimate the 
total cost resulting from some postal shipments having to use a 
different entry type as a result of the rule.

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

    While CBP assumes for this analysis that these costs will fall 
entirely on importers, the incidence of the fees is determined by the 
relative price elasticities of supply and demand. The importers, the 
final deliver-to parties, the exporters, and the brokers will share the 
incidence of these costs to varying extents. How much of the incidence 
each party bears will depend on the relevant price elasticities of 
supply and demand, which CBP is unable to estimate for this analysis. 
The costs will result to some extent in reduced quantity demanded and 
ultimately deadweight loss, which we discuss in a later subsection.
Mail Hiatuses
    As filers and FPOs transition to the new postal informal entry 
process, under the rule there could be temporary hiatuses or reductions 
of mail from certain countries. The different parties currently 
importing through the interim postal process may need time to adapt 
their processes to handle the new data requirements, and importers and 
FPOs who currently use non-broker qualified parties will need to switch 
to a licensed customs broker, as discussed above. If the filers or FPOs 
are unable to adapt immediately, there may be a short period during 
which postal shipping is not available in certain countries. In that 
case, the importers and exporters affected by the hiatus would need to 
ship the goods through a non-postal entry type or wait until the postal 
mode becomes available again. Either of these options would cost more 
or be an inconvenience to the importers and the other parties involved. 
As CBP does not know the extent to which postal shipping might be 
halted in the short-run, CBP is unable to estimate the costs of this 
effect.
Deadweight Loss
    Although this analysis assumes in the Transfers section below that 
the quantity of imports will be unaffected by the rule (setting aside 
any short-run hiatuses), it is likely that the duty increase for postal 
shipments and other cost increases resulting from the rule will cause 
importers to import less. This decrease in imports would correspond to 
a cost to society in the form of deadweight loss. While some of these 
goods will not be imported under the rule, the fact that they would be 
imported in the baseline means that the benefit of those imports to the 
importers exceeds the cost of producing those goods, shipping them, and 
complying with the baseline entry process. Were importers to decide not 
to import some shipments because of the rule, society would be missing 
out on the net gains from trade that would have occurred with those 
shipments. The deadweight loss from the rule is the total value of this 
lost surplus. While CBP lacks the data to estimate deadweight loss in 
this analysis, this could be an important cost of the rule. Also, to 
the extent that there will be deadweight loss under the rule due to a 
decrease in imports, there will be a smaller increase in government 
revenue than CBP's estimate in the Transfers section below, as there 
will be fewer shipments.

Total Costs

    The rule would increase the annual time burden of submitting the 
IMDW to CBP, and this cost is shown in Table 4. Due to data 
limitations, CBP is unable to quantify the other costs that will result 
from the rule. These unquantified costs include the cost of switching 
some goods to a different entry type, the cost to some importers of 
finding a licensed customs broker, the deadweight loss that will result 
from reduced imports, and possibly a short-run hiatus of postal 
shipments for some FPOs. While CBP is unable to estimate these costs, 
it acknowledges that some of them could be significant.

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

Benefits
    In the baseline, postal shipments pay a lower duty rate than non-
postal shipments because the former only have to pay Section 122 
duties, while the latter pay both Section 122 duties and any other 
applicable duties. This disparity between postal and non-postal modes 
will disappear under the rule because postal shipments will be subject 
to all applicable duties and will start providing to CBP the HTSUS 
classification data needed to calculate those duties. The rule will 
therefore lead to an increase in revenue collected by the government. 
Because this benefit to the government will be balanced out by the loss 
to the duty payers, we count this effect as a transfer instead of a 
benefit to society and estimate it in the Transfers section.
    While the increased tax revenue is not a benefit per se, the rule 
does have the benefit of stricter enforcement of trade enforcement 
actions. U.S. trade law explicitly permits the President to impose 
tariffs under certain acts of Congress: the Trade Expansion Act of 1962 
and the Trade Act of 1974. Section 232 of the Trade Expansion Act of 
1962

[[Page 37818]]

allows the President to adjust imports if there are threats that impair 
U.S. national security. Section 201 of the Trade Act of 1974 allows the 
President to impose temporary trade measures if there is ``substantial 
cause or threat of serious injury'' to U.S. industries. Lastly, Section 
301 of the Trade Act of 1974 allows the U.S. Trade Representative to 
impose import restrictions if a trading partner is violating trade 
agreements or engaging in practices that harm U.S. commerce. In this 
analysis, CBP refers to duties imposed under the authority of Section 
232, 201, or 301 as ``trade enforcement actions.'' In the baseline, 
importers and exporters can avoid these trade-enforcement actions by 
importing through the interim postal process, where these duties (and 
all non-Section 122 duties) do not apply. As a result, CBP is unable to 
strictly enforce measures and resultant duties that have been imposed 
for purposes other than revenue collection. Because the rule will 
require shipments subject to trade enforcement actions to use an entry 
type other than the new postal informal entry process, CBP will be able 
to pursue the goals of the trade enforcement actions more effectively.
Transfers
    Shipments entered through the new postal informal entry process may 
be subject to higher duties under the rule than in the baseline, 
resulting in a transfer from duty payers to the U.S. government. As 
discussed earlier, the President suspended de minimis treatment for 
most importations by executive order, which is already factored into 
the baseline of this rule. Therefore, CBP does not include the effects 
of suspending de minimis treatment in this rule. However, duty payments 
on postal shipments could increase because in the baseline the only 
duties applied to postal shipments are based on the Section 122 duties 
established by Proclamation 11012. Under the new postal informal entry 
process, HTSUS classifications will be required for postal shipments, 
and CBP will use this information to assess all applicable duties, such 
as those depending on the product classification and country of origin. 
It is the filers who pay the duties in the postal informal entry 
process, but these duties can be passed on to other parties to the 
transaction such as the importer or the supplier.
    Because CBP was not previously requiring the collection the HTSUS 
classifications for postal shipments, it is unable to say what the 
exact increase in duties on postal shipments would be under the rule. 
Therefore, CBP estimates the increase by assuming that the same 
effective average duty rate that is applied to ET11 entries will also 
apply to postal entries. CBP took a sample of 392,312 ET11 entries from 
September to November of 2025 and calculated the total duties, taxes, 
and fees \68\ (referred to here collectively as duties), excluding the 
IEEPA duties because the IEEPA duties applied to both postal and ET11 
entries (and others).\69\ Dividing those non-IEEPA duties ($13,847,415) 
by the total value of the goods in the sample ($160,675,653) yields 
8.62%, the effective average rate of those non-IEEPA duties. From 
September to November of 2025, $914,623,378 of postal shipments arrived 
in the United States. At that rate, CBP calculates that $3,668,544,318 
of postal shipments would arrive in the United States over one 
year.\70\ Applying the non-IEEPA duties rate of 8.62% to this total, 
CBP estimates that annual duties from postal shipments would increase 
by $316,163,988 under the rule. CBP assumes that -11.63%, the CAGR of 
postal entries over 2021-2024, is the rate at which annual postal 
duties would change over the regulatory period. Applying -11.63% growth 
to the annual duties of $316,163,988, CBP projects the additional 
postal duties under the rule during the regulatory period, shown in 
Table 5. CBP reduces the projected amount in the first and last year by 
half because the rule takes effect midway through the year and the 
period of analysis is 10 years, extending to mid-2036. To the extent 
that postal shipment volumes will be affected by the higher duties or 
that the composition of postal shipments differs from that of ET11 
entries, the true increase in duties will differ from our estimate. CBP 
also notes that in this analysis it did not quantify any additional 
tariffs that might be imposed in the future, because CBP did not have 
enough specific information about the rates and applicability of future 
tariffs.

applicable duty rate for goods shipped via the international postal 
network is ``equal to the rate provided in Proclamation 11012 of 
February 20, 2026,'' which imposed additional duties under Section 
122 of the Trade Act of 1974 (19 U.S.C. 2132) (Section 122). Hence, 
the Section 122 duties are applicable to postal and non-postal 
shipments in the same manner as the formerly applicable IEEPA 
duties.

    Besides the transfers to the U.S. government through increased 
duties, taxes, and fees, the rule may also result in transfers to 
brokers. The rule requires that parties submitting IMDWs to CBP be the 
owner, purchaser, or duly appointed licensed customs brokers. As a 
result, clients that have been using non-broker qualified parties to 
submit IMDWs will switch to using brokers, except for clients whose 
non-broker qualified party becomes a licensed customs broker so that it 
can continue submitting the IMDW under the rule.
Net Impact
    The rule updates the postal informal entry process so that postal 
shipments are subject to all applicable duties. To make this change, 
CBP will require filers to include the product classification and 
relevant duty rate on the IMDW. Furthermore, goods subject to trade 
enforcement and trade remedy actions or PGA data requirements will need 
to make entry some other way than through the new postal informal entry 
process. The rule will therefore strengthen CBP's trade enforcement 
actions and generate revenue from increased duties on postal shipments. 
The projected duty increase is shown in Table 6.

                                  Rule

    These changes to the entry process will also result in costs. 
Filers will face a larger time burden when submitting the IMDW. Some 
importers will have to switch to importing through an entry type other 
than the new postal informal entry process, and some importers and FPOs 
will need to find a broker if their previous qualified party was not a 
licensed customs broker. Difficulties during the transition to the new 
postal informal entry process may cause temporary hiatuses of postal 
shipments. Finally, the higher duties on postal shipments, along with 
the higher costs of complying with the entry process, will result in 
deadweight loss as some importers decide to import less. Due to data 
limitations, CBP was only able to quantify the cost of the increased 
time burden of the IMDW. CBP does not anticipate any cost savings from 
the rule and has analyzed but not quantified the benefits of stricter 
enforcement of trade enforcement actions.
    Table 7 shows the quantified estimates of the costs and net impact 
under the rule. Table 8 shows the discounted net impact during the 
regulatory period of mid-2026 to mid-2036. The increase in duties under 
the rule is not included in these calculations because the revenue is a 
transfer of value from one party (duty payers) to another (the U.S. 
government) that will not have a direct net effect on society as a 
whole. The annualized net impact of the rule is estimated to be a net 
cost of $172,980 per year under a discount rate of 3% or $169,794 under 
a discount rate of 7%. Other potential impacts discussed in this 
analysis, including potential increases in broker fees, additional 
importer compliance burdens for shipments that must use other entry 
types, possible short-term postal shipment hiatuses, and deadweight 
loss from reduced imports, are qualitatively described but not 
quantified, and therefore are not reflected in the quantified net 
impact estimates of the rule.

C. Regulatory Flexibility Act

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.), as amended 
by the Small Business Regulatory Enforcement Fairness Act of 1996, 
requires an agency to prepare and make available to the public a 
regulatory flexibility analysis that describes the effect of a proposed 
rule on small entities (i.e., small businesses, small organizations, 
and small governmental jurisdictions) when the agency is required to 
publish a general notice of proposed rulemaking for a rule. Since a 
general notice of proposed rulemaking was not necessary for this rule, 
CBP is not required to prepare a regulatory flexibility analysis for 
this rule.

D. Paperwork Reduction Act

    In accordance with the Paperwork Reduction Act of 1995, Public Law 
104-13, 109 Stat. 163 (44 U.S.C. 3501 et seq.) (PRA), CBP may not 
conduct, and a person is not required to respond to, a collection of 
information unless the collection of information displays a valid 
control number assigned by the Office of Management and Budget (OMB). 
The collection of information contained in this IFR was submitted to 
OMB for emergency review and authorization under Section 3507(j) of the 
PRA.
    In accordance with Sec.  3507(j)(1)(A) and (B), CBP determined that 
the collection of information described in this IFR is needed prior to 
the expiration of the time periods established under the PRA and is 
essential to the mission of CBP. Delaying the implementation of this 
IFR for purposes of providing public notice and comment in accordance 
with the PRA would be reasonably likely to cause public harm. As noted 
above in section IV.A, CBP also determined that delaying the 
publication of this IFR for the purposes of providing notice and 
comment in general would be impracticable, and contrary to the public 
interest. It would create a significant threat of serious damage to 
important public interests. Additionally, in accordance with Sec.  
3507(j)(1)(B), CBP determined that it cannot reasonably comply with the 
provisions of the PRA because public harm is reasonably likely to 
result if normal clearance procedures are followed.
    As discussed in Section IV.B of the preamble to this rule, in 
recent years there has been a dangerous increase in the volume of low-
value packages. This has led to an unacceptable rate of attempted 
unlawful importations using the de minimis processes and has resulted 
in significant uncollected duties. As such, CBP is making numerous 
changes to the requirements for informal entries, including changes to 
a previously approved information collection. For the reasons stated 
above,

[[Page 37820]]

CBP has determined that it is necessary to request, under Sec.  
3507(j), an emergency authorization for the collection of information 
discussed in this IFR.
    CBP is simultaneously inviting the general public and other Federal 
agencies to comment on the proposed and/or continuing information 
collections, pursuant to Sec.  3506(c)(2)(A). This process is conducted 
in accordance with 5 CFR 1320.8. Written comments and suggestions from 
the public and affected agencies should address one or more of the 
following four points: (1) whether the proposed collection of 
information is necessary for the proper performance of the functions of 
the agency, including whether the information will have practical 
utility; (2) the accuracy of the agency's estimate of the burden of the 
proposed collection of information, including the validity of the 
methodology and assumptions used; (3) suggestions to enhance the 
quality, utility, and clarity of the information to be collected; and 
(4) suggestions to minimize the burden of the collection of information 
on those who are to respond, including through the use of appropriate 
automated, electronic, mechanical, or other technological collection 
techniques or other forms of information technology, e.g., permitting 
electronic submission of responses. The comments that are submitted 
will be summarized and included in the request for approval. All 
comments will become a matter of public record. Such comments can be 
submitted in the regulatory docket for this IFR or by email to 
[email protected].
    Among other things, this IFR will require new data elements on the 
existing International Mail Duty Worksheet (OMB Control Number 1651-
0147).
International Mail Duty Worksheet (1651-0147)
    Estimated Number of Respondents: 100.
    Estimated Number of Total Annual Responses: 1,200.
    Estimated Time per Response: 6 hours.
    Estimated Total Annual Burden Hours: 7,200.

E. Unfunded Mandates Reform Act of 1995

    Title II of the Unfunded Mandates Reform Act of 1995 (2 U.S.C. 
1531-38, UMRA) requires each Federal agency to prepare a written 
statement assessing the effects of any Federal mandate in a proposed 
rule or final rule for which the agency published a proposed rule, 
which includes any Federal mandate that may result in a $100 million or 
more expenditure (adjusted annually for inflation) in any one year by 
State, local, and tribal governments, in the aggregate, or by the 
private sector.
    A written statement under UMRA is not required unless an agency has 
published a notice of proposed rulemaking. See 2 U.S.C. 1532(a). In 
addition, an action is exempt from UMRA if it is necessary for national 
security. See 2 U.S.C. 1503(5). As discussed elsewhere, this rule is 
exempt from notice and comment rulemaking procedures and is necessary 
for national security. Accordingly, CBP has not prepared a written 
statement in connection with this rule.

F. Congressional Review Act

    Before a rule can take effect, 5 U.S.C. 801, the Congressional 
Review Act (CRA), requires agencies to submit the rule and a report 
indicating whether it is a major rule, to Congress and the Comptroller 
General. If a rule is deemed a ``major rule'' by OMB, the CRA generally 
provides that the rule may not take effect until at least 60 days 
following its publication. 5 U.S.C. 801(a)(3). However, the CRA 
provides that if an agency finds good cause that notice and public 
procedure are impracticable, unnecessary, or contrary to the public 
interest, the rule shall take effect at such time as the agency 
determines. 5 U.S.C. 808(2).
    The Administrator of the Office of Information and Regulatory 
Affairs of OMB has determined that this IFR meets the criteria for a 
``major rule'' in 5 U.S.C. 804(2). However, as discussed above, CBP 
finds good cause exists under 5 U.S.C. 808(2) to issue this rule 
notwithstanding the timing requirements for major rules under 5 U.S.C. 
801(a)(3). As explained above, delaying the effectiveness of the new 
postal informal entry process provided for in this rule beyond 30 days 
is impracticable. As explained above, due to the unusual and 
extraordinary circumstances in the de minimis mail environment, 
delaying the implementation of the regulatory suspension of the de 
minimis administrative exception provided for in this rule beyond the 
date of publication could result in a gap during the pendency of the 
notice-and-comment proceedings, thereby allowing illicit drugs, 
violative intellectual property, and other violative goods to enter the 
United States. Requiring 60 days for the rule to take effect would pose 
a threat to the revenue due to the sheer volume of de minimis mail 
shipments that CBP processes on a daily basis without collecting 
revenue. Thus, this rule has two effective dates: the regulatory 
suspension of the de minimis administrative exception is effective on 
the date of publication and all other changes, including the new postal 
informal entry process requirements will take effect 30 days after 
publication. Until the new postal informal entry process requirements 
take effect, importers may use the interim process provided for in 
Section 3 of E.O. 14324, as revised by E.O. 14388.

V. Signing Authority

    In accordance with Treasury Order 100-20, the Secretary of the 
Treasury delegated to the Secretary of Homeland Security the authority 
related to the customs revenue functions vested in the Secretary of the 
Treasury as set forth in 6 U.S.C. 212 and 215, subject to certain 
exceptions. This regulation is being issued in accordance with DHS 
Delegation 07010.3, Revision 03.2, which delegates to the Commissioner 
of CBP the authority to prescribe and approve regulations related to 
customs revenue functions.

    Section 145.15 is also issued under 19 U.S.C. 1623;
* * * * *

0
2. Effective July 24, 2026, amend Sec.  145.12 by revising paragraphs 
(a) and (b) to read as follows:


Sec.  145.12  Entry of merchandise.

    (a) Formal entries--(1) Discretionary. CBP may require formal entry 
of any mail shipment regardless of value if it is necessary to protect 
the revenue.
    (2) Required. Formal entry will be required as follows:
    (i) Formal entry is required for every mail importation which 
exceeds $2,500 in value, except for special classes of merchandise 
which can be released without entry (see subpart D of this

[[Page 37821]]

part), and except as provided in subparts B and C of part 143 and Sec.  
10.1 of this chapter.
    (ii) Formal entry is required for any merchandise of a class or 
kind provided for in any absolute or tariff-rate quota, whether the 
quota is open or closed. In the case of merchandise of a class or kind 
provided for in a tariff-rate quota, the merchandise is subject to the 
rate of duty in effect on the date of entry.
    (iii) Formal entry is required for merchandise subject to any 
antidumping or countervailing duty determination, instruction, or order 
issued by the Department of Commerce; or any other merchandise 
otherwise precluded by law from eligibility for informal entry.
    (iv) Formal entry is required for alcoholic beverages, cigars 
(including cheroots and cigarillos) and cigarettes containing tobacco, 
cigarette tubes, cigarette papers, smoking tobacco (including water 
pipe tobacco, pipe tobacco, and roll-your-own tobacco), snuff, or 
chewing tobacco.
    (v) Formal entry is required for any mail shipment subject to the 
requirements of another government agency.
    (vi) Formal entry is required for any merchandise subject to duties 
under Chapter 98 or Chapter 99 of the Harmonized Tariff Schedule of the 
United States (HTSUS), or for which duty-free treatment is claimed 
under Chapter 98 of the HTSUS or pursuant to a Free Trade Agreement.
    (3) Separate shipments. Separate shipments not exceeding $2,500 in 
value, if mailed abroad at different times (as shown by the declaration 
or other mailing indicia), cannot be combined for the purpose of 
requiring formal entry, even though they reach CBP at the same time and 
are covered by a single order or contract in excess of $2,500, unless 
there was a splitting of shipments in order to avoid the payment of 
customs duty.
    (4) Notice of formal entry requirement. When a formal entry is 
required, the addressee will be notified of the arrival of the shipment 
and of the method by which entry is to be made. If the shipment is 
addressed to a point which is not a CBP port or customs station, the 
port of entry specified in the notice will be the port nearest the 
destination of the shipment. When a formal entry is filed, it must 
contain all the statistical information as provided in Sec.  141.61(e) 
of this chapter.
    (b) Mail and informal entries--(1) Preparation of entry form. 
Except as provided in paragraphs (a), (c), (d), and (e) of this 
section, for each eligible shipment not exceeding $2,500 in value which 
is to be delivered by the Postal Service, a party with the right to 
make entry under Sec.  143.26(a) of this chapter must transmit the 
informal mail entry, as provided in paragraph (b)(3) of this section, 
and pay the applicable rate of duty as provided for in paragraph (b)(2) 
of this section.
    (2) Rates of duty and payment. Merchandise released under a mail 
informal entry will be dutiable at the rates of duty in effect when the 
preparation of the entry is completed. Preparation of the entry is 
completed when the entry is properly transmitted to CBP. Payment must 
be transmitted via Pay.gov no later than the 7th day of the month 
following the arrival of the shipment.
    (3) Postal informal entry process. The following data elements are 
required to be transmitted to CBP via email no later than the 7th day 
of the month following the arrival of the shipment(s):
    (i) Filer Code;
    (ii) Bond Number;
    (iii) Description of Merchandise;
    (iv) Country of Origin of Merchandise;
    (v) All Applicable 10-digit HTSUS Classification(s);
    (vi) Quantity/Weight (conditional and required ONLY if using a 
specific duty rate);
    (vii) Duty Rate;
    (viii) Value;
    (ix) Total Duty Owed;
    (x) Carrier;
    (xi) Flight/Conveyance Number;
    (xii) Tracking Number (generated by the foreign post operator);
    (xiii) Arrival Port; and
    (xiv) Arrival Date.
* * * * *

3. Effective July 24, 2026, add Sec.  145.15 to read as follows:


Sec.  145.15  Bonding requirements for informal mail entries.

    Each shipment valued at $2,500 or less which is to be delivered by 
the United States Postal Service, pursuant to Sec.  145.12(b), will not 
be released from CBP custody unless a single transaction or continuous 
bond containing or meeting the bond conditions set forth in Sec.  
113.62 of this chapter has been transmitted to CBP pursuant to part 113 
of this chapter, and has been secured by an approved corporate surety, 
or cash deposits as provided for in Sec.  113.40 of this chapter.

0
4. Effective June 24, 2026, revise Sec.  145.31 to read as follows:


Sec.  145.31  Importations not over $800 in value.

    (a) Except as provided in paragraph (b) of this section, the port 
director will pass free of duty and tax, without preparing an entry as 
provided for in Sec.  145.12, packages containing merchandise having an 
aggregate fair retail value in the country of shipment of not over 
$800, subject to the requirements set forth in Sec. Sec.  10.151 and 
10.153 of this chapter.
    (b) The exemption provided in paragraph (a) of this section is 
suspended for merchandise arriving through the international postal 
network until such time as CBP determines that the application of the 
exemption is no longer inconsistent with the purpose of 19 U.S.C. 
1321(a), no longer jeopardizes the revenue, and no longer facilitates 
unlawful importations. Notice of a modification or revocation of this 
suspension will be announced by the Commissioner in the Federal 
Register.
