Trump revises 50% tariffs on certain Canadian products, changes take effect October 30

U.S. President Donald Trump has announced changes to the 50 per cent additional tariffs imposed on certain Canadian products, with the revisions set to take effect on October 30, 2026.

The order signed by Donald Trump say, under the proclamation, some Canadian products will no longer face the additional 50 per cent duties, while other products will remain subject to the tariffs. The changes will apply to goods entering the United States for consumption, or withdrawn from warehouses for consumption, on or after 12:01 a.m. Eastern time on October 30.

The additional 50% Section 338 tariff will no longer apply to certain Canadian products, including: Seaweed and other algae that are fresh, chilled, frozen or dried and suitable for human consumption. Propylene polymer sheets and films that are non-adhesive, non-cellular and not reinforced or combined with other materials.Plastic boxes, cases, crates and similar containers used for transporting or packing goods and several types of plywood.

Several Canadian products have been added to the list of goods covered by the additional 50% Section 338 tariffs. These include:

Sweetened cocoa powder containing less than 65% sugar by dry weight. Paints and varnishes, including enamels and lacquers, made from acrylic or vinyl polymers in a nonaqueous medium. Soap and other organic surface-active products used as soap, including bars, cakes, pieces, and soap-impregnated paper, wadding or felt intended for toilet use.Artificial and prepared waxes, wooden packing boxes and cases with solid sides, lids and bottoms.

The tariffs were initially imposed under a July 20 proclamation, with the U.S. administration alleging that Canada’s motor vehicle tariff system discriminated against American commerce. The duties took effect on August 22 after a temporary three-day suspension ended.
