Import Tips
• Verify fiber content exceeds 80% sulfate wood fibers via lab testing to confirm kraft classification
• Provide mill test certificates showing grammage >225 g/m² and uncoated status to avoid misclassification
• Watch for reclassification to 4804.11 if Mullen burst meets kraftliner specs
