For nearly a decade, any shipment worth $800 or less entering the United States cleared duty-free under the Section 321 de minimis exemption (19 U.S.C. §1321(a)(2)(C)). That carve-out quietly carried cross-border e-commerce logistics through three administrations — and it is now suspended for shipments from every country, in every quantity, by every transport mode.

I maintain a free tariff-data project and we rebuilt the full 2016–2026 timeline from 21 dated legal instruments (Federal Register notices, executive orders, Public Laws), each linked to its primary source and cross-checked against the live CFR — including the August/September 2025 executive orders and the October 2026 final rule that made the suspension permanent-looking in the regulations:

Happy to answer questions on how the data pipeline sources and timestamps each instrument.
