Import Tips
• Verify cobalt purity via certified assay reports to confirm classification under 8105.20.60.00 and avoid reclassification as powders
• Include mill test certificates documenting alloy composition, as cobalt content must exceed other metals per Chapter 81 notes
• Ensure proper hazardous material declarations if ingots contain trace impurities; common pitfall is undervaluation based on LME cobalt prices
