BRAVE AI:
Canadian softwood lumber imports into the United States are subject to significant tariffs. As of mid-2026, most Canadian commodity softwood lumber faces a combined tariff burden of approximately 34.83%, which consists of 24.83% in preliminary anti-dumping and countervailing duties and a 10% tariff imposed under Section 232.
Anti-Dumping and Countervailing Duties: These are applied to offset alleged unfair pricing and subsidies. Rates vary by company; for example, Canfor faces a combined rate of 47.59%, while West Fraser faces 26.47%.
Section 232 Tariffs:
In October 2025, the U.S. imposed a 10% global tariff on softwood timber and lumber citing national security, which applies in addition to existing duties.
Exemptions:
Lumber products that comply with USMCA (United States-Mexico-Canada Agreement) rules of origin are generally exempt from broader reciprocal tariffs but remain subject to the specific anti-dumping, countervailing, and Section 232 duties.
Impact:
These tariffs act as a tax on U.S. importers, contributing to higher construction costs in the United States, though they also affect Canadian export revenues and market stability.
Canada supplies approximately 25% to 30% of the softwood lumber consumed in the United States, which accounts for a significant portion of wood building products. In 2024, Canada was the source of nearly half of all U.S. wood product imports, providing roughly $11 billion of the $23 billion total in wood imports.
Specifics of the trade relationship include:
Softwood Lumber Dominance: Canada accounts for 84.3% of all softwood lumber imports into the U.S., supplying about 28.1 million cubic meters in 2024.
Market Share:
While Canada previously supplied over 80% of U.S. softwood imports, recent tariffs and trade disputes have reduced its market share to approximately 71% of softwood lumber imports (valued at $4.5–5.2 billion) as of 2025.
Hardwood Lumber:
The U.S. purchases over 50% of Canada’s total exports of hardwood lumber, though the volume is significantly lower than that of softwood.
Overall Imports:
In 2025, total U.S. imports of wood and articles of wood from Canada were valued at US$10.16 billion, with sawn wood and particle board being the largest categories.
