Canada-U.S. Lumber Duty Dispute Keeps Another Tree Standing
Published Date: 10/19/2026
Notice
Summary
The U.S. Department of Commerce found that some Canadian softwood lumber sellers sold their wood at unfairly low prices during 2024. This means certain companies will face extra duties to level the playing field. These changes take effect starting October 19, 2026, impacting importers and buyers who deal with these lumber products.
Analyzed Economic Effects
6 provisions identified: 0 benefits, 6 costs, 0 mixed.
File reimbursement certificate or risk doubled duties
Importers are reminded they must file a certificate about reimbursement of antidumping and/or countervailing duties prior to liquidation of the relevant entries for this review period. If an importer fails to file the certificate, Commerce may presume reimbursement occurred and assess doubled antidumping duties or increase duties by the amount of countervailing duties.
New antidumping rates on Canadian lumber
The Department of Commerce assigned final antidumping duty margins for imports of certain Canadian softwood lumber for the period January 1, 2024 through December 31, 2024: Canfor group 17.00%, Resolute group 13.13%, West Fraser group 4.71%, and non-selected companies 10.64%. These percentage rates will be used to calculate duties on entries covered by this review.
Cash deposit rules start October 19, 2026
For shipments entered or withdrawn for consumption on or after the publication date (October 19, 2026), importers must post cash deposits equal to the weighted-average dumping margins listed in the final results for the companies under review. If neither the exporter nor the producer is covered in this review or prior segments, the cash deposit rate remains 6.04% ad valorem.
Importers will be assessed importer-specific duties
Commerce will instruct U.S. Customs and Border Protection (CBP) to assess antidumping duties on appropriate entries from the review period using importer- or customer-specific assessment rates based on the ratio of duties to entered value. If an importer-specific rate is zero or de minimis, CBP will liquidate without regard to antidumping duties. Commerce intends to issue assessment instructions no earlier than 41 days after publication of these final results.
Rescission for 105 companies; duties at prior deposit rates
Commerce rescinded the administrative review for 105 companies. For those rescinded companies, CBP will assess antidumping duties on appropriate entries at a rate equal to the cash deposit of estimated antidumping duties required at the time of entry (or withdrawal from warehouse) during January 1, 2024 through December 31, 2024.
Reseller policy can raise liquidation rate
Commerce's reseller policy applies when a reviewed producer/exporter did not know their merchandise sold to an intermediary was destined for the U.S. In those cases, Commerce will instruct CBP to liquidate unreviewed entries at the all-others rate if there is no rate for the intermediate company(ies) involved.
