Postal De Minimis Suspension & New Postal Informal Entry Process

Current understanding

CBP has indefinitely suspended the $800 Section 321 de minimis administrative exemption for merchandise arriving via the international postal network and established a new postal informal entry process for such shipments. This closes the remaining de minimis channel (mail) after the parallel suspension for all other modes of entry, meaning low-value international mail parcels to U.S. consumers now require formal customs treatment. Effect: higher compliance and duty costs for foreign sellers shipping small parcels by mail, new procedural burden on USPS and CBP handling of inbound mail, and likely pass-through to U.S. consumer prices on low-value cross-border e-commerce.

Evidence log

• 2025-05-22 — Closing the De Minimis Loophole Act: cross-connection with closing-de-minimis-loophole-act: The bill’s directive to strengthen postal shipment rules and informal-entry data mirrors CBP’s postal de minimis suspension and new postal informal entry process — legislative and regulatory tracks converging on postal channels. (novelty: 3)
• 2025-03-04 — Closing the De Minimis Loophole Act: cross-connection with closing-de-minimis-loophole-act: Bill’s Treasury postal-fee rulemaking directive parallels the CBP postal informal entry process already established administratively. (novelty: 3)
• 2026-07-30 — Duty Collection for Domestic Mail Arriving From Certain Insular Possessions and Territories: cross-connection with postal-duty-collection-insular-possessions: Both revise Postal Service handling of duty collection and customs clearance on inbound mail; the insular possessions rule extends prepayment obligations to intra-U.S. mail from territories, paralleling the informal entry process created for international postal shipments after de minimis suspension. (novelty: 2)
• 2026-06-24 — Indefinite Suspension of the De Minimis Exemption for Mail Shipments and New Postal Informal Entry Process: cross-connection with de-minimis-exemption-suspension: Paired CBP final rules: the first suspended de minimis for all non-postal modes; the second (this finding) suspends it for the postal network and introduces a bespoke postal informal entry process — together eliminating the $800 de minimis pathway across all import channels. (novelty: 4)
