The U.S. Department of Commerce has lowered the total import tax rate on Canadian softwood lumber to 34.75 per cent. This marks a decrease from the 45 per cent combined rate that was previously reported in August 2025.

Why it matters

The adjustment follows a formal review of import tax rates conducted by the U.S. Department of Commerce. This change modifies the financial landscape for cross-border lumber trade between the two nations.

The new 34.75 per cent rate comprises a 14.11 per cent countervailing duty, a 10.64 per cent anti-dumping rate, and a 10 per cent national security tariff. Officials finalized these figures following a recent agency review.

Market Dynamics
