Import Tips

Verify tungsten purity exceeds 99% by weight to confirm classification under Chapter 81; alloys shift to other base metal headings

Provide mill test certificates documenting chemical composition and mechanical properties to avoid misclassification as scrap

Ensure wire diameter and tolerance specs match 'wire' definition, as thicker forms may classify as bars under 8101.94
