Import Tips & Compliance
• Ensure ISPM 15 heat treatment or fumigation certification for bark-stripped logs to meet quarantine standards
• Label shipments clearly as 'Western or Mountain Hemlock' to prevent confusion with S-P-F or Hem-Fir
• Check for CITES restrictions if logs appear from old-growth stands, though common hemlock typically exempt
