Import Tips
• Verify fiber content exceeds 80% sulfate process via lab testing to confirm uncoated status and avoid reclassification
• Provide mill test certificates showing weight >225 g/m² and bursting strength to prevent customs disputes
• Ensure rolls are not further worked (e.g
• no printing) as that shifts to Chapter 49
