HS Code for CLT

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.

Products Included

Common Misclassification

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.

FAQ

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.
