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.
Laminated Veneer Lumber (LVL)
Engineered wood product composed of thin wood veneers glued together under heat and pressure, forming strong beams for headers, joists, and rim boards in construction. Falls under HTS 4418.89.00.00 as other engineered structural timber products due to veneer lamination for load-bearing capacity.
Cross-Laminated Timber (CLT) Panels
Mass timber panels made by cross-laminating layers of solid-sawn lumber at right angles with structural adhesives, used for walls, floors, and roofs in mid-rise buildings. HTS 4418.89.00.00 covers these as other engineered structural timber products for their orthogonal lamination strength.
I-Joists (Engineered Wood)
Prefabricated structural beams with wood chord members and OSB webs, designed for floor and roof framing in residential construction. HTS 4418.89.00.00 includes these assembled engineered products as other structural timber elements.
Structural Composite Lumber (SCL)
Generic term encompassing LVL, PSL, and LSL engineered products with wood fibers or strands bonded to form dimensional lumber substitutes for framing. Falls under HTS 4418.89.00.00 as other engineered structural timber products.
Laminated Strand Lumber (LSL)
Engineered wood made from aspen strands laminated into billets then ripped into studs and rim boards for framing. HTS 4418.89.00.00 captures LSL as other engineered structural timber.
