Import Tips
• Verify fiber composition via lab testing to confirm ≥80% sulfate/soda wood fibers and exact Mullen burst index to avoid reclassification
• Provide mill test certificates documenting weight (60-115 g/m²), stretch factors, and tear/tensile minima for customs compliance
• Ensure rolls are machine-finished and uncoated; common pitfall is misdeclaring bleached variants which shift to 4804.41
