Product classification
HS code for CLT: 4418.82
Wood, engineered structural timber products, cross-laminated timber (CLT or X-lam).
Classification of CLT under HS 4418.82
Cross-laminated timber (CLT), also known as X-lam, is classified under HS code 441882. This classification specifically covers engineered structural timber products. CLT is characterized by its unique construction method, where layers of solid-sawn lumber are stacked perpendicularly to adjacent layers and then bonded together with structural adhesives. This cross-lamination provides enhanced dimensional stability, strength, and rigidity, making it suitable for structural applications in construction. The HS code 441882 precisely identifies CLT within the broader category of wood products, distinguishing it from other forms of engineered wood based on its specific manufacturing process and structural properties.

Codes often confused with 4418.82
Common mistake. Common misclassification for CLT often occurs with other engineered wood products. For instance, glued laminated timber (glulam), which consists of parallel laminations of wood bonded together, is classified under HS code 441881. Plywood, another engineered wood product made from thin sheets of wood veneer, falls under HS code 4412. Particle board (4410) and fibreboard (4411) are also distinct, differing significantly in their composition and manufacturing. The key distinction for 441882 is the cross-laminated structure of solid timber layers, which sets it apart from products with parallel laminations or those made from veneers, particles, or fibers. Careful examination of the product's internal structure and manufacturing process is crucial to avoid misclassification.
Top exporters and importers of HS 441882 (the code used for CLT), 2025
In 2025, the largest exporter of HS 441882 (the code used for CLT) 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).

Questions about CLT
What is the HS code for CLT?
The HS code for CLT is 441882 (Wood; engineered structural timber products, cross-laminated timber (CLT or X-lam)).
How do I classify CLT for customs?
CLT is classified under HS code 441882 — Wood; engineered structural timber products, cross-laminated timber (CLT or X-lam). This is a 6-digit subheading level code.
What is the HS code for Cross-Laminated Timber (CLT)?
The HS code for Cross-Laminated Timber (CLT) is 441882.
What distinguishes CLT from other engineered wood products under HS code 4418?
CLT is distinguished by its construction method involving layers of solid-sawn lumber stacked perpendicularly and bonded together. This cross-lamination provides unique structural properties, differentiating it from products like glulam (441881) which use parallel laminations.
Which countries are the top exporters of CLT (HS 441882)?
In 2025, the top exporters of HS 441882 (the code used for CLT) in UN Comtrade data were Austria ($360M, 67% of world exports), Germany ($90M) and Czechia ($27M). World exports came to about $539M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
