The U.S. Department of Commerce finalized antidumping and countervailing duty rates on Canadian softwood lumber totaling 24.75%, down from about 35.16%, according to the National Association of Home Builders. The new rates take effect after publication in the Federal Register; a separate 10% tariff means total duties are reported at 34.75%.
The U.S. Department of Commerce has finalized lower antidumping and countervailing duties on Canadian softwood lumber, setting the combined rates at 24.75%, down from about 35.16%, according to the National Association of Home Builders (NAHB). The revised rates will take effect after they are published in the Federal Register, while a separate 10% tariff means the reported total duties on imports remain 34.75%.
Commerce issued its final rates on October 13, concluding the latest annual administrative review of U.S. duties on Canadian lumber. The 24.75% figure combines the antidumping and countervailing duty rates. Antidumping duties address imports that U.S. authorities find are sold at less than fair value; countervailing duties address subsidies that authorities find benefit foreign producers.
The new rates are not yet in effect. They are scheduled to take effect following publication in the Federal Register, the step that formally publishes federal agency actions. The source report does not specify when that publication will occur.
The lower review rates do not remove all charges on Canadian softwood lumber. A separate 10% tariff imposed by the Trump administration after a Section 232 national security investigation remains part of the reported total. Hardware Retailing, citing the NAHB, said total duties on lumber imports are 34.75% when that tariff is included.
How the Rate Change Affects Lumber Costs
The reduction changes one part of the U.S. import-cost calculation for Canadian softwood lumber. Importers and companies that buy or sell lumber may need to account for the revised antidumping and countervailing rates once the final action takes effect. The reported combined rate, however, remains higher than 24.75% once the separate tariff is included.
That distinction matters for readers tracking lumber prices, construction inputs and trade costs: the rate cut is not a complete removal of duties, and the available report does not establish how much of the change will be reflected in prices paid by builders or consumers. The effect will depend on factors such as the timing of implementation and how businesses handle import costs.

Commerce’s Seventh Administrative Review
The final decision followed Commerce’s seventh set of administrative reviews of the U.S. antidumping and countervailing duty orders covering Canadian softwood lumber. The agency began the review process last year and released preliminary findings on April 13, before issuing the final rates on October 13.
Administrative reviews revisit the rates applied under existing trade orders. The current action concerns those review rates; it does not, according to the source report, change the separate 10% tariff imposed after the administration’s Section 232 investigation. The NAHB was the cited source for the revised rates and reported total.

Federal Register Timing and Price Effects
The Federal Register publication date is not specified in the source report, so the effective date of the revised rates remains unknown. The report also does not provide a breakdown of the antidumping and countervailing portions of the 24.75% combined rate, or identify how the final rates vary among companies or shipments.
It is also unclear whether, when or by how much the lower review rates will affect lumber prices. The cited material reports the duty changes but does not include pricing data, statements from Canadian producers or importers, or an estimate of effects on construction costs. The separate 10% tariff is described as still applying in the reported total.
Publication Will Set the Effective Date
The next stated step is publication of Commerce’s final rates in the Federal Register. The revised antidumping and countervailing duties are to take effect after that publication. Until the date is confirmed, importers and other businesses affected by the orders will need to track the federal notice for implementation details.
Further information may clarify the effective date and how the final rates apply across covered imports. The source material does not identify another scheduled review milestone or indicate that the separate 10% tariff is changing.
Key Questions
What rates did the U.S. Department of Commerce finalize?
Commerce finalized combined antidumping and countervailing duties of 24.75% on Canadian softwood lumber, down from about 35.16%, according to the NAHB.
Are the new duties in effect now?
Not based on the source report. The rates take effect after publication in the Federal Register; the publication date was not provided.
Why is the reported total 34.75%?
The reported total adds a separate 10% tariff to the 24.75% in antidumping and countervailing duties. The tariff followed a Section 232 national security investigation, according to the report.
Does the lower rate mean lumber prices will fall?
The source report does not say whether prices will fall or estimate any price effect. It reports the duty change, not how businesses will pass import costs through to buyers.
What review led to the rate change?
The final rates came from Commerce’s seventh set of administrative reviews of the existing softwood lumber antidumping and countervailing duty orders. Preliminary findings were released April 13, and final rates were issued October 13, 2026.
