Glulam Beams
Glued laminated timber beams made from layered softwood or hardwood lumber bonded with adhesives, used in structural applications like roof trusses and columns. Classified under HTS 4418.89.00.00 as engineered structural timber products (other) due to the lamination process creating enhanced structural properties beyond simple sawn wood.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not laminated or engineered
Coniferous sawn timber without gluing falls under coniferous wood sawn headings.
If used for plywood production
Laminated sheets for plywood rather than structural beams go to plywood classifications.
If not primarily structural
Non-structural joinery like decorative beams classified as other builders' joinery.

Import Tips & Compliance
• Verify adhesive composition meets EPA TSCA Title VI standards for formaldehyde emissions
• Provide mill certificates documenting wood species, strength grades, and lamination process
• Avoid misclassification as rough sawn lumber by emphasizing engineered bonding in documentation
