HS Code for Cobalt oxide

Cobalt oxides and hydroxides are classified under HS code 2822.00. This heading falls within Chapter 28, which covers inorganic chemicals and organic or inorganic compounds of precious metals, of rare-earth metals, of radioactive elements or of isotopes. Specifically, 2822.00 is reserved for separate chemically defined compounds of cobalt. According to the Chapter Notes, this heading includes cobaltous oxide (CoO), which is a grey, brown, or greenish powder, and cobaltic oxide (Co2O3), which is a black powder. It also covers commercial cobalt oxides, which are often mixtures of these oxides. These substances are typically produced by the roasting of cobalt ores or the thermal decomposition of cobalt salts like cobalt nitrate or carbonate. The classification is determined by the chemical nature of the product as an oxide or hydroxide of the base metal cobalt. It is a separate chemically defined compound, which distinguishes it from raw ores or metallic alloys.

Products Included

• Cobaltous oxide (cobalt monoxide)
• Cobaltic oxide (cobalt trioxide)
• Cobaltosic oxide (tri-cobalt tetroxide)
• Commercial cobalt oxides
• Cobalt hydroxides

Common Misclassification

Cobalt oxide is often confused with cobalt ore (HS code 2605.00). The distinction is that ore is a naturally occurring mineral, while the oxide is a chemically processed compound. Another common misclassification is with prepared pigments, opacifiers, and colors used in the ceramic or glass industries, which are classified under HS code 3207.10. If the cobalt oxide is mixed with other substances to form a prepared pigment, it must be moved to Chapter 32. Additionally, cobalt salts like cobalt sulfate (2833.29) are sometimes confused with oxides, but they belong to different headings within Chapter 28. Distinguishing between these requires verification of the chemical formula and intended industrial application.
