Spruce Cross-Laminated Timber Panels
Cross-laminated timber (CLT) panels made from layered spruce lumber boards, glued orthogonally for enhanced structural strength. Classified under HTS 4418.82.00.00 as engineered structural timber products specifically for cross-laminated timber (CLT or X-lam). Used in walls, floors, and roofs of modern buildings.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as unlaminated sawn spruce lumber before CLT assembly
Sawn or chipped lengthwise softwood lumber falls under heading 4412, not assembled engineered products.
If classified as other assembled builders' joinery rather than specifically CLT
Non-specific engineered wood joinery goes to 4418.90; CLT has dedicated subheading 4418.82.
If made from fiberboard or particleboard layers instead of solid lumber
Density fiberboard (MDF/HDF) panels use heading 4411, not solid wood CLT.

Import Tips & Compliance
• Obtain structural engineering certifications and grading stamps (e.g
• APA or SPIB) to prove compliance with US building codes
• Include mill certificates showing glue type (e.g
• PUR adhesives) and low formaldehyde emissions to meet EPA TSCA Title VI
• Avoid misclassification as sawn lumber by providing assembly documentation showing orthogonal lamination process
