Products classified under HTS 4418.81.00.00
Douglas Fir Glulam Beams
Glue-laminated timber beams made from Douglas fir laminations bonded with adhesives, designed for structural load-bearing applications in construction. These beams meet the definition of glulam under HTS 4418.81 as engineered structural timber products consisting of multiple wood layers glued together. Commonly used in residential and commercial building frameworks.
Southern Pine Glulam Columns
Cylindrical glue-laminated columns from southern pine species, engineered for vertical load support in timber frame buildings. Classified under HTS 4418.81 as glulam due to the glued lamination of dimensional lumber. Ideal for post-and-beam construction projects.
Western Red Cedar Glulam Roof Trusses
Pre-engineered glue-laminated roof truss components from western red cedar, laminated for high strength-to-weight ratio. Falls under HTS 4418.81.00.00 as glulam engineered structural timber, not complete joinery. Used in exposed roof applications for aesthetic and structural benefits.
Hem-Fir Glulam I-Joists
Engineered I-shaped joists with Hem-Fir glulam flanges and OSB webs, used for floor and roof framing. Classified as glulam under HTS 4418.81 due to the glued laminated flange components meeting structural timber criteria. Provides long-span capabilities in modern construction.
S-P-F Glulam Lumber
Glue-laminated lumber from Spruce-Pine-Fir mixed stands, dimensionally stable for headers and beams. HTS 4418.81 classification applies as engineered glulam with multiple laminations per definition. Common in Canadian-sourced structural applications.
Laminated Veneer Lumber (LVL) Beams
LVL beams produced by gluing thin wood veneers parallel to grain, functioning as high-strength glulam alternative. Though veneer-based, classified under HTS 4418.81 as glue-laminated structural timber when used similarly. Essential for rim board and header applications.
GluLam Arched Roof Beams
Curved glue-laminated beams from select hardwoods, custom-engineered for arched roof structures. Meets HTS 4418.81 glulam specs through layered gluing allowing complex shapes. Popular in timber-framed arenas and churches.
Mass Timber Glulam Columns
Extra-wide glue-laminated columns for cross-laminated timber (CLT) building systems, supporting multi-story mass timber construction. HTS 4418.81 applies as core glulam structural elements. Revolutionizing sustainable high-rise building.
Glulam Bridge Girders
Heavy-duty glue-laminated girders designed for pedestrian and highway bridge superstructures. Classified under HTS 4418.81 as engineered glulam for structural timber applications. Treated for exterior durability in infrastructure projects.
Fire-Retardant Glulam Beams
Glue-laminated beams pressure-impregnated with fire-retardant chemicals for enhanced building safety. Retains HTS 4418.81 classification as glulam structural timber with added treatment. Meets IBC fire code requirements for exposed wood.
Curly Maple Glulam Posts
Decorative structural posts from laminated curly maple hardwood, combining aesthetics with strength. HTS 4418.81 glulam classification for engineered glued timber used in exposed interior applications. Premium finish for custom homes.
Radiata Pine Glulam Headers
Engineered headers from New Zealand Radiata pine laminations for door and window rough openings. Precise HTS 4418.81 glulam classification for structural glued members. Cost-effective for volume residential construction.
European Larch Glulam Rafters
Sloped glue-laminated rafters from European larch for pitched roof systems. Durable glulam per HTS 4418.81 for exterior structural use. Natural resistance to decay enhances longevity.
Bamboo Glulam Beams
Engineered beams from laminated bamboo strips, per chapter note including woody materials as wood. HTS 4418.81 glulam for structural glued laminations. Sustainable alternative for green building projects.
Hybrid Glulam-Steel Beams
Composite beams combining glulam core with steel flitch plates for enhanced strength. Primary wood classification under HTS 4418.81 as glulam timber with metal reinforcement. Used in seismic zones requiring hybrid performance.
