I-Joists (Engineered Wood)
I-joists are prefabricated structural beams consisting of wood flanges (typically LVL or solid lumber) and an oriented strand board (OSB) web, joined to form an I-shaped cross-section. They are widely used for floor and roof framing in residential and light commercial construction. As assembled engineered structural timber products, they are classified under this tariff item.

Cross-Laminated Timber (CLT) Panels
Cross-laminated timber (CLT) panels are large-format structural panels made by stacking and gluing layers of solid-sawn lumber at right angles. They are used as load-bearing walls, floors, and roofs in mid-rise and tall wood buildings. CLT falls under this tariff item as an engineered structural timber product not elsewhere specified.
Engineered 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 roofs and floors in residential and commercial buildings. These trusses are classified under this tariff item as other engineered structural timber products.
Glulam Beams
Glulam beams are engineered structural members made by bonding layers of dimension lumber with moisture-resistant adhesives, forming large beams, columns, and arches. They are used in roofs, bridges, and heavy timber frames. Glulam is an engineered structural timber product classified under this tariff item.
Laminated Strand Lumber (LSL)
Laminated strand lumber (LSL) is an engineered wood product made from aspen or other hardwood strands oriented and bonded with adhesives under pressure, then cut into studs, rim boards, and headers. It is used as a structural framing material. LSL falls under this tariff item as other engineered structural timber.
Laminated Veneer Lumber (LVL)
Laminated veneer lumber (LVL) is an engineered wood product made from thin veneers glued together under heat and pressure, with grain oriented parallel to the length. It is used for beams, headers, joists, and rim boards in construction. LVL is classified under this tariff item as other engineered structural timber.
Mass Plywood Panels (MPP)
Mass plywood panels (MPP) are thick structural panels made by laminating multiple layers of veneer into panels 6 inches or more in thickness, used for shear walls and load-bearing walls in mass timber construction. They are engineered structural timber products classified under this tariff item.
