In a Presidential Proclamation published on October 23, 2026, the White House announced modifications to the list of Canadian products subject to the 50% Section 338 tariffs.

As of October 30, 2026, the following goods will no longer be subject to the Section 338 tariffs:

• Certain seaweeds and other algae;
• Non-adhesive plates, sheets, film, foil and strip of polymers of propylene;
• Certain plywood sheets under several tariff subheadings, including products with various outer ply materials;
• Bleached paper and paperboard, corrugated paperboard cartons, boxes, and cases, and paper pulp; and
• Certain industrial machinery and refrigeration equipment.

The modifications also add more than 100 products that will now be subject to Section 338 tariffs. The newly covered products span several industries and include, but are not limited to cocoa powder, acrylic paints, soaps, artificial waxes, chemical residuals, vinyl flooring, fiberboard, and certain carpet products.

These changes will go into effect at 12:01 a.m. Eastern Time on October 30, 2026.
