Duty Rate (from China)
Products classified under Tariff item 4418.81.00.00
Bamboo Glulam Beams
Engineered beams made from laminated bamboo strips, bonded with adhesives to form structural members. Under Chapter 44 Note 6, bamboo is treated as wood, and these beams meet the definition of glue-laminated timber (glulam) for load-bearing applications.
4418.81.00Curly Maple Glulam Posts
Decorative structural posts made from laminated curly maple hardwood, combining aesthetic grain with engineered strength. These glue-laminated posts are suitable for exposed interior applications and meet the definition of glulam under heading 4418.
4418.81.00Douglas Fir Glulam Beams
Glue-laminated timber beams made from Douglas fir laminations bonded with adhesives, designed for structural load-bearing applications. These beams meet the definition of glulam as engineered structural timber products under tariff item 4418.81.00.
4418.81.00European Larch Glulam Rafters
Sloped glue-laminated rafters from European larch for pitched roof systems, offering natural decay resistance. These structural members are engineered through lamination and fall under glulam as defined in tariff item 4418.81.00.
4418.81.00Fire-Retardant Glulam Beams
Glue-laminated beams pressure-impregnated with fire-retardant chemicals for enhanced building safety. The treatment does not alter the glulam classification, as it remains engineered structural timber under tariff item 4418.81.00.
4418.81.00GluLam Arched Roof Beams
Curved glue-laminated beams from select hardwoods, custom-engineered for arched roof structures. The layered gluing process allows complex shapes while maintaining structural integrity, qualifying as glulam under tariff item 4418.81.00.
4418.81.00Glulam Bridge Girders
Heavy-duty glue-laminated girders designed for pedestrian and highway bridge superstructures. These engineered structural members are treated for exterior durability and meet the glulam definition under tariff item 4418.81.00.
4418.81.00Hem-Fir Glulam I-Joists
Engineered I-shaped joists with Hem-Fir glulam flanges and OSB webs, used for floor and roof framing. The glued laminated flange components meet the structural timber criteria, classifying the product as glulam under tariff item 4418.81.00.
4418.81.00Hybrid Glulam-Steel Beams
Composite beams combining a glulam core with steel flitch plates for enhanced strength. The primary wood classification applies as glulam timber with metal reinforcement, falling under tariff item 4418.81.00 for engineered structural timber.
4418.81.00Laminated Veneer Lumber (LVL) Beams
LVL beams produced by gluing thin wood veneers parallel to grain, functioning as high-strength glulam alternatives. Though veneer-based, they are classified as glue-laminated structural timber under tariff item 4418.81.00 when used similarly.
4418.81.00Mass Timber Glulam Columns
Extra-wide glue-laminated columns for cross-laminated timber (CLT) building systems, supporting multi-story mass timber construction. These core glulam structural elements fall under tariff item 4418.81.00 as engineered structural timber.
4418.81.00Radiata Pine Glulam Headers
Engineered headers from New Zealand Radiata pine laminations for door and window rough openings. These structural glued members meet the glulam definition and are classified under tariff item 4418.81.00 for cost-effective residential construction.
4418.81.00Southern Pine Glulam Columns
Cylindrical glue-laminated columns from southern pine species, engineered for vertical load support in timber frame buildings. The glued lamination of dimensional lumber qualifies as glulam under tariff item 4418.81.00.
4418.81.00S-P-F Glulam Lumber
Glue-laminated lumber from Spruce-Pine-Fir mixed stands, dimensionally stable for headers and beams. This engineered glulam with multiple laminations meets the definition under tariff item 4418.81.00 and is common in Canadian construction.
4418.81.00Western Red Cedar Glulam Roof Trusses
Pre-engineered glue-laminated roof truss components from western red cedar, laminated for high strength-to-weight ratio. These glulam engineered structural timber products fall under tariff item 4418.81.00, not complete joinery.
