Import Tips
• Verify purity and chemical definition per Chapter 28 Note 1 to ensure classification as cobalt carbonate, not organo-inorganic compounds
• Provide Certificate of Analysis (CoA) confirming CoCO3 composition; common pitfall is contamination shifting to 2842 for complex salts
• Check REACH/SVHC restrictions on cobalt compounds; label toxicity warnings for industrial handling
