The U.S. Department of Commerce set Canadian softwood lumber antidumping and countervailing duties at 24.75%, down from about 35.16%, after an annual review. The lower rates take effect after publication in the Federal Register, while a separate 10% tariff means the stated total duties remain 34.75%.
The U.S. Department of Commerce has set antidumping and countervailing duties on Canadian softwood lumber at 24.75%, down from about 35.16%, following its annual review. The new rates, issued October 13, will take effect after publication in the Federal Register; a separate 10% tariff means the stated total duties on lumber imports remain 34.75%, according to the National Association of Home Builders.
The finalized 24.75% rate combines the antidumping and countervailing duties applied under U.S. orders on Canadian softwood lumber. Commerce began its seventh set of administrative reviews of those orders last year and released preliminary findings on April 13, according to the report by Hardware Retailing, citing the NAHB. The October 13 decision sets the final rates for this review.
The lower figure does not remove the separate tariff described in the report. The Trump administration imposed a 10% tariff on timber and softwood lumber after a Section 232 national security investigation. With that charge included, the report gives the total duties on lumber imports as 34.75%. It does not explain how the separate tariff is applied to individual shipments or how the combined charges are calculated in every case.
The final rates are not yet in force based on the information provided. Commerce’s decision is scheduled to take effect following publication in the Federal Register. The source material does not give a publication date, so importers and buyers will need to watch for the formal notice to establish when the revised rates begin applying.
How the Rate Cut Affects Lumber Costs
The reduction changes a significant trade cost attached to Canadian lumber entering the U.S. market. A lower antidumping and countervailing duty rate could reduce that portion of the charge for importers, but the continued 10% separate tariff means the overall duty burden is not reduced to 24.75%. The report identifies the combined total as 34.75%.
That distinction matters to businesses that buy, import, distribute or sell lumber. Duty changes can affect landed costs and commercial decisions, but the source does not report whether companies will pass any savings on to customers or how prices will respond. No price forecast or estimate of consumer impact is provided, so those outcomes remain uncertain.
For the housing and building-supply sectors, the decision is a change in the import-cost environment rather than a removal of trade measures. The NAHB is the cited source for the rate change, but the material does not provide a statement from the association about the expected market effect. The final 34.75% total is the figure presented in the report, and the applicable amount for particular transactions may depend on details not included there.

Commerce’s Seventh Annual Review
The new rates stem from Commerce’s seventh administrative review of the antidumping and countervailing duty orders on Canadian softwood lumber. Such reviews determine the rates applied under those orders for the period under examination. The source says the review began last year, with preliminary findings released on April 13 and final rates announced on October 13, 2026.
The review addresses two types of duties: antidumping measures and countervailing measures. The reported combined rate for those duties falls from about 35.16% to 24.75%. Separately, the administration’s 10% tariff followed a Section 232 national security investigation, making it distinct from the rates Commerce finalized through this administrative review.
The distinction between the review duties and the separate tariff explains why the headline rate reduction does not equal an end to the charges on Canadian lumber. The available report does not set out the full history of the trade dispute, identify individual company rates, or describe how the final rate compares with those applied to every exporter. Those details should not be inferred from the aggregate figures provided.

Effective Date and Market Effects
The exact effective date remains unknown in the source material. The rates take effect after publication in the Federal Register, but no publication schedule or notice date is provided. Until that publication occurs, the report does not establish that importers are already paying the revised 24.75% review rate.
The material also does not explain whether every Canadian exporter or shipment is covered by the same rate, how the separate tariff interacts with the duties in specific transactions, or whether other charges apply. It gives no estimate of the effect on lumber prices, construction costs, supply or retail sales. Those outcomes should not be treated as confirmed consequences of the decision.
Federal Register Notice Sets Timing
The next procedural milestone is publication of Commerce’s final rates in the Federal Register. That notice will determine when the new antidumping and countervailing duty rates take effect. Importers, lumber sellers and builders will be able to use the published details to assess the timing and terms of the change.
After publication, the market impact will depend on how the revised review rates and the separate tariff apply to individual imports, as well as on business pricing and purchasing decisions. The source provides no dates for further agency action and no forecast of price changes. Until more detail is available, the confirmed development is the lower finalized review rate, alongside the separate tariff and the stated 34.75% total.
