Products classified under Tariff item 4418.89
Cross-Laminated Timber (CLT) Panels
Cross-laminated timber (CLT) panels are mass timber panels made by stacking and gluing layers of solid-sawn lumber at right angles, creating a strong, dimensionally stable product for walls, floors, and roofs. They are classified under this tariff item as 'other' builders' joinery and carpentry of wood, as they are assembled engineered wood panels not elsewhere specified. CLT panels are increasingly used in mid-rise and tall wood construction projects.
4418.89.00Engineered Wood Trusses
Engineered wood trusses are pre-assembled structural frameworks made from dimension lumber or engineered wood members, connected with metal plates or gussets. They are used for roof and floor support in residential and commercial buildings. These assembled carpentry products are classified under this tariff item as 'other' builders' joinery of wood.
4418.89.00Glulam Beams
Glulam beams are engineered structural members made by bonding layers of dimension lumber with moisture-resistant adhesives, creating large beams, columns, and arches. They are used in roofs, bridges, and heavy timber frames. As assembled engineered wood products, they are classified under this tariff item for 'other' builders' joinery and carpentry of wood.
4418.89.00I-Joists (Engineered Wood)
I-joists are prefabricated engineered wood beams consisting of solid or laminated wood flanges connected by an oriented strand board (OSB) web, forming an 'I' cross-section. They are used as floor and roof joists in residential and light commercial construction. As assembled structural carpentry products, they fall under this tariff item for 'other' builders' joinery and carpentry of wood.
4418.89.00Laminated Strand Lumber (LSL)
Laminated strand lumber (LSL) is an engineered wood product made from aspen or other wood strands oriented and bonded with adhesives into large billets, then cut into studs, rim boards, and other framing members. It is used as a structural substitute for solid lumber in residential and commercial construction. LSL falls under this tariff item as 'other' engineered structural timber products.
4418.89.00Laminated Veneer Lumber (LVL)
Laminated veneer lumber (LVL) is an engineered wood product made by layering thin wood veneers with adhesives under heat and pressure, forming strong beams, headers, and rim boards. It is widely used in residential and commercial framing. LVL is classified under this tariff item as 'other' engineered structural timber products in builders' joinery.
4418.89.00Mass Plywood Panels (MPP)
Mass plywood panels (MPP) are thick, structural plywood panels made by laminating multiple layers of veneer into panels over 6 inches thick, used for shear walls and mass timber construction. They are distinct from standard plywood due to their thickness and structural role. MPPs are classified under this tariff item as 'other' engineered structural wood products.
4418.89.00Parallel Strand Lumber (PSL)
Parallel strand lumber (PSL) is an engineered wood product made from long, oriented wood strands bonded with waterproof adhesives under pressure, forming high-strength beams and headers. It is used in heavy construction for load-bearing applications. PSL is classified under this tariff item as 'other' engineered structural timber products.
4418.89.00Structural Composite Lumber (SCL)
Structural composite lumber (SCL) is a generic category encompassing engineered wood products like LVL, PSL, and LSL, made from wood fibers or strands bonded with adhesives to form dimensional lumber substitutes. It is used for framing, beams, and headers. SCL products are classified under this tariff item as 'other' engineered structural timber products.
