Cobalt(II) Carbonate Powder from China
Cobalt(II) carbonate (CoCO3) is a pinkish-white inorganic salt used primarily as a precursor in the production of cobalt oxide pigments and catalysts. It falls under HTS 2836.99.10.00 as a chemically defined cobalt carbonate, distinct from stabilized or complex forms excluded by Chapter 28 notes.

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
