GUIDANCE: Federal Register Notice Published on De Minimis Requirements Per Executive Order 14256 and Guidance for Carriers Transporting International Mail

Plain-English explanation

CSMS 64861116 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin (operational), published on April 25, 2025. It carries the official CBP guidance brokers and importers must follow for the topic — "GUIDANCE: Federal Register Notice Published on De Minimis Requirements Per Executive Order 14256 and Guidance for Carriers Transporting International Mail". CSMS messages are the operational layer between Commerce determinations and at-the-border collections: when Commerce publishes a new rate, scope ruling, or instruction, CBP turns it into a CSMS that ACE/ACS systems and brokers act on.

CSMS # 64861116 - GUIDANCE: Federal Register Notice Published on De Minimis Requirements Per Executive Order 14256 and Guidance for Carriers Transporting International Mail U.S. Customs and Border Protection sent this bulletin at 04/25/2025 05:34 PM EDT   Cargo Systems Messaging Service CSMS # 64861116 - GUIDANCE: Federal Register Notice Published on De Minimis Requirements Per Executive Order 14256 and Guidance for Carriers Transporting International Mail On April 24, 2025, the “ Notice of Implementation of Additional Duties on Products of the People’s Republic of China Pursuant to the President’s Executive Order 14256, Further Amendment to Duties Addressing the Synthetic Opioid Supply Chain in the People’s Republic of China as Applied to Low-Value Imports ” was placed on public inspection in the Federal Register.   The notice implements Executive Order 14256 of April 2, 2025, as amended.  Accordingly, effective 12:01 a.m. eastern daylight time on May 2, 2025, covered goods will not receive the administrative exemption from duty and certain taxes under 19 U.S.C. § 1321(a)(2)(C), known as the “de minimis” exemption. Goods described in Section 2(a) of Executive Order 14195, “Imposing Duties To Address the Synthetic Opioid Supply Chain in the People’s Republic of China” (90 FR 9121, Feb. 7, 2025), as amended, that are not sent through international mail, must be entered under an appropriate entry type, such as a type 11 or 01 entry, in ACE, and will be subject to all applicable duties, taxes, and fees.  Requests for de minimis entry and clearance for ineligible shipments will be rejected. Separate instructions are provided below and attached for goods described in Section 2(a) of Executive Order 14195 that are sent through international mail from China or Hong Kong. As noted in the Federal Register Notice, CBP is temporarily suspending the parenthetical exception clause in 19 CFR 143.21(a) (pertaining to articles valued in excess of $ 250 classified in Chapter 99, Subchapters III and IV, HTSUS).  This temporary suspension of the parenthetical exception clause in 19 CFR 143.21(a) applies to all modes of entry and all countries of origin.  CBP systems will be updated to reflect this temporary suspension on April 30, 2025, and filers will be able to file a Type 11 informal entry for articles valued at up to $ 2,500.  As also noted in the FRN, CBP is temporarily suspending 19 CFR 145.12(b) (pertaining to CBP’s preparation of informal mail entry).  This temporary suspension of 19 CFR 145.12(b) applies to all informal mail entries from China or Hong Kong, regardless of value.  Consequently, during the temporary suspension of 19 CFR 145.12(b), formal entry will be required for mail shipments from China or Hong Kong valued at over $ 800. Trade filers are strongly advised not to submit manifests or entries for de minimis clearance on any shipment containing articles described in Section 2(a) of Executive Order 14195, as amended, that are products of China or Hong Kong and that will arrive on or after 12:01 a.m. eastern daylight time on May 2, 2025. Such shipments will be rejected for de minimis clearance beginning at 12:01 am eastern daylight time on May 2, 2025. Attached to this CSMS is detailed guidance for carriers transporting international mail that outlines how to comply with the requirements of Executive Order 14256, as amended, to collect and remit payment of the duties on international mail packages from China or Hong Kong. The procedures attached to this CSMS do not apply to carriers that do not transport international mail.

Frequently asked questions

What is CSMS 64861116?

CSMS 64861116 is a U.S. Customs and Border Protection (CBP) Cargo Systems Messaging Service bulletin titled "GUIDANCE: Federal Register Notice Published on De Minimis Requirements Per Executive Order 14256 and Guidance for Carriers Transporting International Mail". CSMS bulletins are the operational instructions CBP issues to brokers, importers, and ACE filers covering rate changes, system updates, scope guidance, and other day-to-day customs-operations changes.

When was CSMS 64861116 published?

CBP published CSMS 64861116 on April 25, 2025. The bulletin's instructions are typically operative as of the publication date unless the body specifies a different effective date.

Is the CBP CSMS the legally binding instruction?

Yes — for at-the-border filing and entry collection. CSMS messages translate Commerce's Federal Register determinations into operational CBP instructions that ACE/ACS systems and brokers execute. The Federal Register notice is the underlying legal authority; the CSMS is the operational implementation. Both should be read together when reconciling a rate or scope change.
