Import Tips

• Verify uniform bleaching and exact fiber composition via lab tests to confirm >95% chemical pulp for 4804.52 compliance

• Provide mill certificates showing grammage ≥225 g/m² and uncoated status; common pitfall is classifying coated versions under 4810

• Ensure documentation specifies 'base stock for packaging' end-use to prevent reclassification as generic paperboard
