Import Tips & Compliance
• Verify uniform bleaching and exact fiber content (>95% chemical process) via lab certification to avoid reclassification to lower headings
• Measure grammage precisely as >225 g/m²; provide Mullen burst test results if claiming kraftliner status for potential duty differences
• Ensure documentation shows uncoated status and not for printing (Chapter 49) or converted articles (Chapter 48 headings 4814+)
