Products classified under Tariff item 4418.82.00
CLT Stair Flight Panels
Pre-cut cross-laminated timber panels forming complete stair flights for mid-rise buildings. These panels are engineered structural timber products made by gluing layers of wood in alternating orientations, providing strength and stability for stair applications. They fall under this tariff item as cross-laminated timber (CLT) structural products.
Douglas Fir CLT Wall Panels
Pre-cut cross-laminated timber panels from Douglas fir, orthogonally glued for load-bearing walls in multi-story construction. These panels are engineered structural timber products with layers of wood stacked crosswise, providing high strength and dimensional stability. They are classified under this tariff item as cross-laminated timber (CLT) structural products.
Fire-Retardant Treated CLT Panels
Cross-laminated timber panels pressure-impregnated with fire retardant for exposed interior applications. The fire-retardant treatment enhances safety but does not alter the fundamental nature of the product as CLT. They remain classified under this tariff item as cross-laminated timber structural products.
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. These panels are engineered structural timber products made by cross-laminating layers of wood, providing excellent load-bearing capacity. They are classified under this tariff item as cross-laminated timber (CLT) products.
Large Span CLT Roof Deck Panels
Heavy-duty cross-laminated timber panels engineered for 40+ foot clear spans in commercial roofing. These panels are structural CLT products with orthogonally glued layers, designed for large-scale applications. They fall under this tariff item as cross-laminated timber (CLT) structural products, regardless of size or span.
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. These panels are engineered structural timber products with layers of wood glued in alternating directions, providing rigidity and fire resistance. They are classified under this tariff item as cross-laminated timber (CLT) structural products.
Pine Cross-Laminated Timber Floor Panels
CLT flooring panels constructed from cross-laminated southern yellow pine boards, designed for multi-span structural floors. These panels are engineered structural timber products with orthogonally glued layers, offering high strength for flooring. They fall under this tariff item as cross-laminated timber (CLT) structural products.
Spruce Cross-Laminated Timber Panels
Cross-laminated timber (CLT) panels made from layered spruce lumber boards, glued orthogonally for enhanced structural strength. These panels are engineered structural timber products designed for various building applications. They are classified under this tariff item as cross-laminated timber (CLT) structural products.
SYP Cross-Laminated Timber Shear Walls
Pre-manufactured shear wall panels from cross-laminated Southern Yellow Pine (SYP), engineered for seismic zones. These panels are structural CLT products with orthogonal lamination, providing excellent shear resistance. They fall under this tariff item as cross-laminated timber (CLT) structural products.
Western Red Cedar CLT Panels
Cross-laminated timber panels made from premium western red cedar, valued for natural decay resistance in exterior applications. These panels are engineered structural timber products with orthogonally glued layers, combining aesthetics with durability. They are classified under this tariff item as cross-laminated timber (CLT) structural products.
