Import Tips
• Verify fiber composition exceeds 80% sulfate process wood fibers via lab testing to confirm kraftliner status and avoid reclassification
• Provide mill test certificates showing weight ≥225 g/m² and Mullen burst strength to prevent delays at customs
• Ensure product is in rolls or sheets, uncoated, and not printed or further processed per chapter note 3
