Why It Matters
Importers, brokers, and logistics providers in the international postal network have until January 20, 2027, to comply with formal-entry requirements for certain merchandise, after U.S. Customs and Border Protection pushed back the prior compliance date of October 22.
The delay matters because the underlying rules, established by a June 24 interim final rule, indefinitely suspended the de minimis administrative exemption for merchandise arriving through the international postal network and created a new postal informal entry process.
The affected shipments fall into three categories: merchandise subject to partner government agency requirements, merchandise subject to duties under Chapter 98 or Chapter 99 of the Harmonized Tariff Schedule of the United States (HTSUS), and merchandise for which duty-free treatment is claimed under Chapter 98 of the HTSUS or pursuant to a Free Trade Agreement.
The Broader Context
The June 24 interim final rule was adopted consistent with Executive Order 14324 of July 30, 2025, titled "Suspending Duty-Free De Minimis Treatment For All Countries," as modified by Executive Order 14388 of February 20, titled "Continuing the Suspension of Duty-Free De Minimis Treatment for All Countries."
The agency says importers, brokers, and logistics providers in the international postal network need additional time "to update their internal systems, develop policies and procedures for submission of relevant data, and to develop the technological infrastructure needed to comply with these requirements." CBP also warned that "failure to afford the public extra time to comply with these requirements could lead to disruptions in the flow of important international postal shipments destined to Americans."
CBP issued the extension as a final rule without a public comment period, invoking the good-cause exception to the Administrative Procedure Act on the ground that "the public comment period would overtake the current compliance deadline of October 22," which would have prevented affected parties from benefiting from the extension. The document imposes no new substantive regulatory requirements; it solely extends the compliance date.
The Bottom Line
The underlying June 24 interim final rule remains unchanged: the indefinite suspension of the de minimis exemption under 19 U.S.C. 1321(a)(2)(C) for merchandise arriving through the international postal network took effect June 24, and the new informal entry process for postal merchandise valued at $2,500 or less took effect July 24. The informal entry process established by that rule remains in place during the extended compliance period; the delay does not revert to any prior practice.
Parties that already have compliant processes in place may voluntarily comply before January 20, 2027, and the Entry Type 13 voluntary electronic mail process for eligible shipments valued at $2,500 or less, which began September 22, remains available as an optional alternative to formal entry for eligible shipments during the extended window.
The new compliance date for 19 CFR § 145.12(a)(2)(v) and (vi) is January 20, 2027.
