This bill tightens the “de minimis” rule for small packages entering the U.S. Right now, shipments worth $800 or less can come in without tariffs, fees, or taxes. The bill would block that duty‑free treatment for items already under special trade actions, like antidumping or countervailing duties, safeguard measures, actions against unfair trade practices (Section 301), or national‑security tariffs (Section 232) . It also bans splitting one order into many packages to get around the rules, requires more detailed product codes for certain countries to use de minimis, and sets civil fines for violations. These changes start 30 days after the bill becomes law.

Key points

• What changes: Certain imports can no longer use the $800 duty‑free rule if they’re under trade remedies (antidumping/countervailing, safeguard, Section 301, or Section 232).
• Extra data: To qualify for de minimis, goods from countries under Section 301 must include a 10‑digit HTS code in the entry filing to U.S. Customs and Border Protection.
• No splitting orders: You can’t divide one order into multiple packages to claim the de minimis benefit.
• Penalties: $5,000 for the first violation; $10,000 for each later one, on top of any other penalties.
• When: Applies starting 30 days after enactment.
