Product classification
HS code for Wood I-beams: 4418.83
Wood, engineered structural timber products, I beams.
Classification of wood I-beams under HS 4418.83
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.

Codes often confused with 4418.83
Common mistake. 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.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
