Canada dominates US supply, with Australia and China also among the leading sources. Importers should note that Canadian softwood lumber products, including engineered structural members, have historically been subject to antidumping and countervailing duty orders, making ADD/CVD exposure a key classification and cost consideration. The single US tariff line covering this product is 4418830000.

Canadian softwood lumber and related engineered structural products have been subject to antidumping and countervailing duty orders. Importers should verify the current scope of any applicable orders with CBP or a licensed customs broker before entry, as scope rulings on engineered wood members can be product-specific.
A timber I-beam is characterized by its I-shaped cross-section — typically solid or laminated wood flanges bonded to a structural panel web. Products that do not exhibit this flanged-web geometry may fall under other headings for engineered structural timber (e.g., 441889) or glued laminated timber. The specific profile and manufacturing method are the key classification factors.
