Product classification
HS code for Cross laminated timber: 4418.82
Wood, engineered structural timber products, cross-laminated timber (CLT or X-lam).
Classification of cross laminated timber under HS 4418.82
Cross-laminated timber (CLT) is classified under HS code 4418.82. This classification is part of Chapter 44, which covers wood and articles of wood. Heading 4418 specifically addresses builders' joinery and carpentry of wood, including cellular wood panels and assembled flooring panels. Within this heading, the 80-series subheadings were updated in recent years to specifically identify engineered structural timber products. CLT is defined by its unique construction: layers of solid-sawn lumber (usually three, five, or seven) oriented at right angles to one another and bonded with structural adhesives. This cross-orientation provides the material with high structural rigidity and stability in two directions, making it suitable for load-bearing walls, floors, and roofs in mass timber buildings. The classification under 4418.82 is mandatory because it is an engineered structural product, distinguishing it from simple plywood or standard laminated wood.

Codes often confused with 4418.82
Common mistake. CLT is often confused with HS code 4412, which covers plywood, veneered panels, and similar laminated wood. While both involve layers of wood, 4412 is generally for decorative or non-structural panels, whereas 4418.82 is specifically for engineered structural carpentry. Another common misclassification is HS code 4418.81, which is reserved for Glue-laminated timber (Glulam). Glulam differs from CLT because its laminations run parallel to the length of the member, whereas CLT layers are cross-oriented. Using the general code 4418.99 for "other" builders' joinery is also an error now that specific codes for engineered timber exist.
Top exporters and importers of HS 441882 (the code used for cross laminated timber), 2025
In 2025, the largest exporter of HS 441882 (the code used for cross laminated timber) in UN Comtrade data was Austria, with 67% of world exports; the largest importer in UN Comtrade data was Germany, with 21% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
