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
