Import Tips & Compliance
• Provide fire-resistance documentation (e.g
• NFPA 703) as many US jurisdictions require treated CLT
• Declare exact dimensions and lamination specs to prevent reclassification as dimension lumber
• Include supplier's quality control records showing shear and bending strength test results
