Import Tips
• Provide APA trademark certification proving structural rating (e.g
• Exposure 1); unrated panels risk detention
• Declare exact strand orientation; random orientation may classify as generic particle board without OSB premium
• Check for moisture content <8% to prevent mold claims; include kiln-drying certificates
