Import Tips
• Verify fiber composition and saturation process documentation to confirm classification as felt paperboard, avoiding misclassification as coated paper under 4811
• Provide mill test reports showing Mullen burst strength and weight to prove compliance with uncoated felt specs; common pitfall is inadequate roofing end-use certification
• Ensure rolls or sheets are not further worked (e.g
• no printing or perforation) per chapter note, or risk reclassification to chapter 48 headings like 4823
