Import Tips

Verify fiber content exceeds 80% sulfate wood fibers via lab testing to confirm kraft classification and avoid reclassification

Provide mill test certificates documenting grammage (150-225 g/m²) and unbleached status for CBP review

Watch for common pitfalls like misdeclaring as bleached (4804.51) or under 150 g/m², leading to penalties
