HS Code for Wood I-beams

Wood I-beams are classified under HS code 4418.83, which specifically addresses engineered structural timber products. These are structural components used in building construction, typically consisting of top and bottom flanges made of solid sawn lumber or laminated veneer lumber (LVL) and a web made of oriented strand board (OSB) or plywood. The classification under 4418 is reserved for builders' joinery and carpentry of wood. The 2022 HS update introduced specific subheadings for engineered wood products like I-beams to better track trade in these specialized construction materials. These products are designed to provide high strength-to-weight ratios and are distinct from standard sawn timber due to their composite, engineered nature. They are primarily used as floor joists and roof rafters in residential and commercial framing. To qualify for this code, the product must be an assembled structural component rather than a simple piece of lumber or a single sheet of plywood.

Products Included

• Engineered wood I-joists
• Prefabricated wood I-beams for roofing
• Composite timber floor beams
• LVL-flanged wood I-beams

Common Misclassification

Wood I-beams are often misclassified under 4407, which covers simple sawn or chipped wood. They may also be confused with 4418.60 (posts and beams), but 4418.83 is the more specific code for I-shaped engineered products. Another error is using 4412, which is for plywood and laminated wood panels that have not been assembled into structural beams.
