Import Tips

Verify purity and form via chemical analysis certificates to confirm classification as zirconium sponge under 'other' articles

Include mill test reports documenting non-alloy status (zirconium >99% by weight) to avoid misclassification as Chapter 81 alloys

Check for waste/scrap exclusion; ensure documentation proves it's prime material to prevent duty disputes
