U.S. Customs Update: Changes to Section 338 Tariffs on Canadian Products Coming October 30th

On October 23, the U.S. President signed a new proclamation that changes which Canadian products are subject to the 50% Section 338 tariffs. The changes apply to goods entered, or withdrawn from warehouse for consumption, on or after 12:01 a.m. ET on October 30, 2026.

What’s new

• More products added, including certain cocoa powder, paints, soaps, vinyl flooring, carpets, wood and paper goods, canoes, chest freezers, valves, instruments and waste products.
• Existing products removed, including certain plywood sheets, paper products, machinery, refrigeration equipment, and packing crates and boxes.

What stays the same

• The rate is still an additional 50%, which stacks on other tariffs
• The tariffs apply to goods that qualify under CUSMA.

Please find more details in the official proclamation. HS lists can be found in Annex I and II.
