De minimis: every CBP message
Section 321 of the Tariff Act of 1930 allows low-value shipments, $800 or less per person per day, to enter free of duty and with less paperwork. Duty-free treatment ended for products of China and Hong Kong in May 2025 and was paused for all countries on August 29, 2025. The pause was extended in February 2026.
CBP’s CSMS messages on de minimis cover Type 86 and Section 321 entries, which shipments still qualify, postal shipments, and how to file shipments that no longer do.
