The long-standing antidumping and countervailing duty orders on softwood lumber from Canada apply specifically to softwood species and do not cover hardwood lumber. Hardwood sawn lumber imports are subject to their own HTS subheadings and, depending on species and origin, may face separate trade-remedy proceedings or none at all. Importers should verify the current order scope before assuming a product is covered or excluded.

Species identification matters for both HTS classification and, increasingly, for sustainability certification (FSC, SFI) required by major retail and construction buyers. For certain tropical hardwood species, CITES documentation may also be required. Accurate species declaration on entry documents is essential to avoid misclassification and potential enforcement action.
