Cobalt(II, III) Oxide Powder from Mexico
High-purity Cobalt(II, III) oxide (Co3O4), also known as cobalt tetroxide, in fine powder form used primarily as a precursor in ceramics and battery production. This chemically defined inorganic compound falls under HTS 2822.00.0010 as a commercial cobalt oxide due to its specific mixed-valence structure. It is essential for manufacturing lithium-ion battery cathodes and magnetic materials.

Import Tips
• Verify purity certificate to confirm it meets 'chemically defined' criteria per Chapter 28 Note 1; ensure SDS includes CAS 1308-06-1
• Common pitfall: classifying as cobalt metal (HTS 8105) if not oxidized
