Last updated: April 2026 dataSoftwood dimensional lumber — pine, spruce, fir, hemlock, and related species sawn, chipped, sliced, or peeled to thicknesses exceeding 6 mm — is one of the most commercially significant wood trade categories entering the US market. Canadian softwood lumber has been subject to antidumping and countervailing duty orders for decades, making country of origin a critical compliance variable for every shipment. The heading encompasses planed, sanded, and finger-jointed boards in addition to rough-sawn stock, so the degree of secondary processing affects both classification precision and value for duty calculations.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The US has maintained antidumping and countervailing duty orders on Canadian softwood lumber through multiple administrative reviews. Importers must deposit estimated duties at the time of entry, and final duty rates are determined through annual administrative reviews by the Department of Commerce. Cash deposit rates vary by Canadian province and producer, so importers should consult the most current Federal Register notices and work with a licensed customs broker.
No — the heading explicitly includes wood that is planed, sanded, or finger-jointed, provided it remains over 6 mm thick. However, if the product is continuously shaped along its edges or faces (e.g., tongue-and-groove or shiplap profiles), it moves into the separately defined heading for profiled coniferous wood.
