Import Tips & Compliance
• Obtain ISPM 15 compliant fumigation certificate if kiln-dried; verify 'not treated' status matches chemical-free requirement
• Provide precise species documentation proving Douglas-fir (Pseudotsuga menziesii) origin to avoid reclassification
• Measure actual thickness post-surfacing to confirm exceeds 6mm; common pitfall is kiln shrinkage below threshold
