U.S. changes which Canadian goods face the 50% extra duty
The U.S. removed 22 tariff classifications and added 100 to the Canadian products subject to the additional 50% Section 338 duty. The revised coverage applies to consumption entries and warehouse withdrawals from 12:01 a.m. Eastern on 30 October 2026.
What changed
Proclamation 11076 changes the product list, rather than placing every Canadian import under a new uniform duty. Removed items include specified corrugated cartons and packaging machinery; additions include specified shampoos, cocoa powders and vinyl flooring.
The exact eight-digit HTSUS codes in Annexes I and II control. CBP identifies 9903.03.14 for covered goods and says the additional duty can also apply alongside Section 232 duties.
Three checks for import teams
- Compare the exact product code with both the removal and addition lists; broad product names cannot settle coverage.
- Check Canadian origin and the consumption-entry or warehouse-withdrawal time against the 30 October trigger.
- Recalculate entry costs using CBP CSMS 70314289, including applicable Chapter 99 reporting and other duties.
