Cobalt(II) Oxide (CoO)
Cobalt(II) oxide is a chemically defined inorganic compound of cobalt used primarily as a precursor in ceramics and glass coloring. It falls under HTS 2822.00.00.90 as a commercial cobalt oxide, distinct from pure cobalt(II,III) oxide, meeting Chapter 28 definitions for inorganic metal oxides.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If commercial cobalt(II,III) oxide
Pure or commercial Co3O4 falls under the specific subheading for cobalt(II,III) oxide.
If impure or contains organic stabilizers
Mixtures or preparations not chemically defined per Chapter 28 notes shift to chemical preparations.
If used as luminophore in phosphors
Inorganic products used as luminophores are excluded to heading 3206 per Chapter 28 note.

Import Tips & Compliance
• Verify purity and chemical definition per Chapter 28 Note 1 to avoid misclassification as mixtures
• Include Safety Data Sheets (SDS) and Certificates of Analysis for customs clearance
• Ensure proper UN hazard labeling as it may be toxic; common pitfall is incomplete hazmat documentation
