U.S. softwood lumber duties (combined antidumping and countervailing) have been a structural feature of Canadian-U.S. trade for decades. Combined rates have varied 8-25% by mill and review period. Individual mill determinations affect specific producers; administrative reviews adjust rates annually.
This guide covers Canadian Softwood Lumber Duty Deep Dive. For SMB importers and exporters, the practical implementation depends on volume, sector, and operational structure.
For background, see /usmca-cusma/ and our complete cross-border practice.
Combined AD/CVD framework
AD addresses Canadian lumber sold below fair value in U.S. market. CVD addresses Canadian government subsidies (provincial stumpage). Combined rate applies.
Individual mill determinations
Specific Canadian mills can request individual rate determination. Lower individual rates often available for cooperative mills.
Scope rulings
Specific lumber products at scope boundaries can request scope rulings. Engineered wood, treated lumber, finished products sometimes outside scope.
Administrative reviews
Annual reviews adjust rates based on prior year data. Importers can participate to argue for lower rates.
