TL;DR
The U.S. Department of Commerce set antidumping and countervailing duties on Canadian softwood lumber at 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; with a separate 10% tariff, the reported total is 34.75%.
The U.S. Department of Commerce has set final antidumping and countervailing duties on Canadian softwood lumber imports at 24.75%, down from about 35.16%, according to the National Association of Home Builders. The new rates follow an annual administrative review and will take effect after they are published in the Federal Register; a separate 10% tariff means the reported combined charge is 34.75%.
Commerce issued its final rates on October 13, concluding the seventh set of administrative reviews of the U.S. antidumping and countervailing duty orders on Canadian softwood lumber. The department’s preliminary findings had been released on April 13, after the review began the prior year, according to the report by Hardware Retailing.
The 24.75% figure covers the two trade-remedy duties together. The 10% timber and softwood lumber tariff is separate: the source says it was imposed by the Trump administration after a Section 232 national security investigation. Including that tariff, the total reported duties on lumber imports are 34.75%.
The lower rate is not yet in effect. The report says the final duties will take effect following publication in the Federal Register. It does not provide a publication date or explain how the final rate applies to individual exporters or shipments.
How the Rate Affects Lumber Costs
A lower antidumping and countervailing duty rate could reduce one component of the charges applied to Canadian lumber entering the United States. Canadian softwood lumber is a significant cross-border building material, so changes to its import costs may matter to lumber suppliers, retailers and home builders. The reported reduction is 10.41 percentage points compared with the previous combined rate of about 35.16% for those two duties.
That change does not mean the overall tariff burden falls to 24.75%. The separate 10% tariff remains part of the reported calculation, producing a combined rate of 34.75% before any other applicable costs or charges. The source does not quantify how the revised rates will affect lumber prices, supply, or construction costs, so those outcomes should not be treated as established.
The distinction between the two measures matters for businesses planning purchases or pricing. The administrative review changes the antidumping and countervailing duties, while the Section 232 tariff is a separate measure. The available report does not say that Commerce’s review altered that tariff.

Commerce Review and Separate Tariff
The duties come from U.S. trade orders addressing Canadian softwood lumber. Commerce periodically reviews those orders; this latest process was the seventh administrative review. The department issued preliminary findings in April and final rates in October, following the sequence described by the National Association of Home Builders and Hardware Retailing.
Antidumping and countervailing duties are distinct trade remedies, though the report presents their final rates as a combined figure. The additional 10% charge has a different basis: a Section 232 national security investigation, according to the source. Keeping those measures separate helps explain why the 24.75% review result does not equal the 34.75% total reported for imports.

Publication and Import-Level Details
The Federal Register publication date is not specified in the source, and the final rates are described as taking effect only after publication. Until that step occurs, the report does not establish when importers will begin applying the revised duties.
The source also does not provide the detailed rate schedules for individual Canadian producers or exporters, explain whether exceptions apply, or describe the treatment of goods already in transit. It reports a combined 24.75% rate and a 34.75% total after the separate tariff, but does not offer shipment-specific guidance. Any effect on retail lumber prices, availability or homebuilding costs remains unquantified.

Federal Register Publication Sets Start
The immediate next step is publication of Commerce’s final rates in the Federal Register, which the source identifies as the condition for the duties to take effect. Importers and other businesses will need the published notice for the effective date and any detailed instructions or rate information it contains.
Until that notice appears, the reported October 13 decision is the confirmed development, while the effective date and practical impact remain open. The separate 10% tariff is reported as continuing alongside the revised duties; the source gives no indication of a change to it.
