Products classified under HTS 4418.82.00.00
Spruce Cross-Laminated Timber Panels
Cross-laminated timber (CLT) panels made from layered spruce lumber boards, glued orthogonally for enhanced structural strength. Classified under HTS 4418.82.00.00 as engineered structural timber products specifically for cross-laminated timber (CLT or X-lam). Used in walls, floors, and roofs of modern buildings.
Douglas Fir CLT Wall Panels
Pre-cut cross-laminated timber panels from Douglas fir, orthogonally glued for load-bearing walls in multi-story construction. Falls under HTS 4418.82.00.00 as CLT structural products distinguished by cross-layering technique.
Pine Cross-Laminated Timber Floor Panels
CLT flooring panels constructed from cross-laminated southern yellow pine boards, designed for multi-span structural floors. HTS 4418.82.00.00 covers these engineered panels due to their specific cross-lamination manufacturing process.
Hem-Fir Cross-Laminated Timber Roof Panels
Structural CLT roof panels from mixed hemlock-fir lumber (Hem-fir), orthogonally laminated for long-span roofing applications. Specifically classified under HTS 4418.82.00.00 for cross-laminated timber products.
Western Red Cedar CLT Panels
Cross-laminated timber panels made from premium western red cedar, valued for natural decay resistance in exterior applications. HTS 4418.82.00.00 applies to all CLT regardless of species due to manufacturing process.
SYP Cross-Laminated Timber Shear Walls
Pre-manufactured shear wall panels from cross-laminated Southern Yellow Pine (SYP), engineered for seismic zones. Classified under 4418.82.00.00 as CLT structural products with orthogonal lamination.
Mixed Softwood CLT Elevator Shaft Panels
Cross-laminated timber panels from mixed spruce-pine-fir (S-P-F) for elevator shaft enclosures in tall buildings. HTS 4418.82.00.00 specifically identifies CLT structural panels per nomenclature.
Fire-Retardant Treated CLT Panels
Cross-laminated timber panels pressure-impregnated with fire retardant for exposed interior applications. Still classified under HTS 4418.82.00.00 as CLT, with treatment noted separately.
Large Span CLT Roof Deck Panels
Heavy-duty cross-laminated timber panels engineered for 40+ foot clear spans in commercial roofing. HTS 4418.82.00.00 covers all CLT regardless of size or span capability.
CLT Stair Flight Panels
Pre-cut cross-laminated timber panels forming complete stair flights for mid-rise buildings. Classified as CLT structural products under HTS 4418.82.00.00.
