Import Tips

• Verify fiber composition exceeds 80% sulfate/soda wood fibers via lab testing to confirm kraft status and avoid reclassification

• Provide mill test certificates showing weight ≥225 g/m² and unbleached status; common pitfall is misdeclaring bleached variants

• Ensure documentation distinguishes from heading 4802/4803 newprint base paper to prevent duty adjustments
