Product classification
HS code for Glued laminated timber: 4418.81
Wood, engineered structural timber products, glue-laminated timber (glulam).
Classification of glued laminated timber under HS 4418.81
Glued laminated timber, commonly referred to as glulam, is classified under HS code 4418.81. This classification is part of Chapter 44, which covers wood and articles of wood, specifically under heading 4418 for builders' joinery and carpentry of wood. The 2022 Harmonized System updates introduced specific subheadings for engineered structural timber products to better track these sustainable building materials. Glulam is distinguished by its construction: multiple layers of dimensional lumber bonded together with moisture-resistant structural adhesives. Because these are finished structural components intended for use in the construction of buildings or civil engineering works, they are classified as "builders' joinery" rather than simple sawn wood or basic plywood. The classification requires that the product be an engineered structural member where the grain of all laminations runs parallel to the longitudinal axis, providing high strength and stability for large-scale architectural projects.

Codes often confused with 4418.81
Common mistake. Glulam is frequently misclassified under HS code 4407, which covers wood sawn or chipped lengthwise. However, 4407 is for basic lumber, whereas glulam is a manufactured structural component. It is also confused with HS code 4412, which covers plywood and veneered panels; glulam differs because its laminations are parallel, unlike the cross-grained layers in plywood. Furthermore, it must be distinguished from Cross-Laminated Timber (CLT), which is classified under 4418.82.
Top exporters and importers of HS 441881 (the code used for glued laminated timber), 2025

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).
