Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as unfinished coniferous wood boards
Plain sawn wood without glulam processing is under 4409 for construction lumber.
If fully assembled into complete door or window frames
Assembled joinery products like frames are in 4418.20, beyond raw glulam.
If made with bamboo or woody materials in thin veneers
Laminated bamboo products may classify under 4412 if meeting plywood definitions.

Import Tips & Compliance
• Submit truss design calculations certified by a professional engineer to confirm glulam classification
• Document adhesive formulation to prove compliance with formaldehyde emission standards like CARB Phase 2
• Package securely to prevent delamination during shipping, which could lead to reclassification claims
