Import Tips
• Verify coating composition meets kaolin/inorganic criteria via lab testing to avoid reclassification to heading 4811
• Provide mill test certificates confirming multi-ply structure, basis weight over 150 g/m², and no other coatings
• Declare exact ply count and end-use (e.g
• packaging) to prevent pitfalls with composite goods rules
