Canadian softwood lumber imports are set to face a lower combined duty rate following a finalized federal trade review, offering a reduction in import costs while leaving a separate tariff in place. Announced October 14, the final determination by the U.S. Department of Commerce lowers the combined antidumping and countervailing duty rate for most covered Canadian producers from 35.16% to 24.75%.

The revised rates consist of a 10.64% antidumping duty and a 14.11% countervailing duty for most non-selected Canadian producers. When the separate 10% tariff imposed under Section 232 is included, the total trade burden falls to 34.75%, compared with 45.16% under the previous rates. The revised rates took effect upon publication in the Federal Register on October 19, 2026. Actual rates may vary by producer.

For lumber and building-material dealers, the change could influence the cost of imported products and purchasing decisions in the months ahead. However, the continued application of tariffs means Canadian lumber will remain subject to substantial additional costs. The impact on individual businesses will depend on their suppliers, sourcing arrangements, and the extent to which changes in import costs are reflected in market prices.

Cross-border trade remains an important component of the North American building-materials market. As trade policies continue to evolve, dealers must account for potential changes in material costs, supply availability, and procurement planning.

ABMA will continue to follow developments in lumber trade policy and share relevant updates with members as new information becomes available.
