The U.S. Department of Commerce set combined antidumping and countervailing duty rates on Canadian softwood lumber at 24.75%, down from about 35.16%, following an annual review. The rates take effect after Federal Register publication, while a separate 10% tariff means total duties are reported at 34.75%.

The U.S. Department of Commerce has set combined antidumping and countervailing duties of 24.75% on Canadian softwood lumber imports, down from about 35.16% under the previous rates. The final rates were issued October 13 after an annual review and will take effect after publication in the Federal Register, according to the National Association of Home Builders (NAHB), as reported by Hardware Retailing.

The new 24.75% rate covers the two trade remedies: antidumping duties and countervailing duties. Commerce reached the final rates as part of its seventh set of administrative reviews of the U.S. duty orders on Canadian softwood lumber. The agency began the review last year and published preliminary findings on April 13, the source report said.

The 24.75% rate is not the full amount of duties described in the report. A separate 10% tariff on timber and softwood lumber, imposed by the Trump administration after a Section 232 national security investigation, brings the reported total duties on lumber imports to 34.75%. That separate tariff is distinct from the antidumping and countervailing rates set in the annual review.

The reported reduction is 10.41 percentage points compared with the previous combined rate of about 35.16%. The change does not apply immediately: the final rates are scheduled to go into effect only following Federal Register publication. The source report did not provide a publication date.

Costs for Canadian Lumber Imports

The reduced trade-remedy rate could lower one part of the duty burden on Canadian lumber entering the United States. However, the separate 10% tariff remains part of the total described in the report, so importers and buyers should not read 24.75% as the overall rate. The reported combined total remains 34.75% once that tariff is included.

Softwood lumber is used in residential construction and other building projects. Changes to import costs may matter to lumber buyers, suppliers, retailers and builders, although the source material does not quantify any expected change in prices or describe how companies will respond. The practical effect will also depend on when the revised rates take effect and how the separate tariff is applied.

The Seventh Duty Review

The duties stem from U.S. antidumping and countervailing duty orders covering Canadian softwood lumber. Antidumping measures address imports that authorities determine are sold at less than fair value; countervailing measures address subsidies. The current development is the final result of Commerce’s seventh administrative review, rather than a report that the underlying orders have ended.

Commerce released preliminary findings on April 13 before issuing the final rates on October 13, according to the Hardware Retailing report. Separately, a Section 232 national security investigation preceded the administration’s 10% tariff on timber and softwood lumber. These measures have different stated bases and are counted separately in the report’s calculation of total duties.

Publication Date and Market Effects

The source report does not state when the final rates will appear in the Federal Register, so the date they become effective is not established in the material provided. It also does not identify how the new rates will be allocated among individual Canadian exporters or provide details about any company-specific rates.

The report gives no estimate of the effect on lumber prices, construction costs or import volumes. It also does not describe any response from Canadian officials, lumber producers, U.S. importers or builders. The 34.75% total is the report’s stated calculation combining the 24.75% trade-remedy rates with the separate 10% tariff; it is not presented as a newly issued Commerce rate for every shipment.

Federal Register Publication Awaits

The next stated milestone is publication of Commerce’s final rates in the Federal Register. After publication, the 24.75% antidumping and countervailing duty rates are expected to take effect. The source material does not specify a publication schedule or describe any further review or appeal process, so those details remain unconfirmed here.

Importers, lumber suppliers and construction businesses will be watching for the publication date and further information on how the final rates apply. Any assessment of price or supply effects will require details beyond the rates reported so far.
