Last updated: August 2026 dataGlulam — structural beams and columns built from multiple softwood or hardwood laminations bonded with structural adhesives — has become a primary material in mass-timber construction, and Canada is the leading US supplier given its proximity and established softwood lumber industry. Austria and Germany are significant European sources, particularly for large-dimension architectural glulam used in exposed-structure applications. The single US tariff line (4418810000) covers all glulam regardless of species or dimension, but importers should note that Canadian softwood glulam may fall within the scope of softwood lumber antidumping and countervailing duty orders depending on species and product form.

The scope of US softwood lumber trade remedy orders has historically included certain glulam products made from covered softwood species. Whether a specific glulam beam is in scope depends on the species composition and the current Commerce Department scope rulings. Importers of Canadian softwood glulam should obtain a scope determination or consult a licensed customs broker before entry to confirm whether AD/CVD deposits are required.
Glulam consists of laminations all oriented with their grain running parallel to the length of the member, producing a beam or column optimized for bending along one axis. CLT (441882) is built from layers with alternating perpendicular grain orientations, creating a panel product with biaxial strength. The grain orientation of the laminations is the definitive classification criterion.
