2822.00.00 - Cobalt oxides and hydroxides; commercial cobalt oxides

This HTS category, 2822.00.00, specifically covers cobalt oxides and hydroxides, including those commercially produced. These are inorganic chemical compounds primarily derived from the metal cobalt. The scope is limited to these oxidized or hydroxylated forms of cobalt, distinguishing them from elemental cobalt or other cobalt salts and compounds that fall under different tariff codes.

Within the broader Chapter 28, which deals with inorganic chemicals, this code is positioned to capture specific cobalt compounds. It differentiates itself from other metal oxides and hydroxides covered elsewhere in Chapter 28 by its exclusive focus on cobalt. The distinction from elemental cobalt (which would be classified under a different heading) or cobalt alloys is also critical for accurate import and export declarations.

The subcategories under 2822.00.00 provide for further differentiation based on specific types of cobalt oxides. Code 2822.00.00.10 identifies cobalt(II, III) oxide, also known as cobalt tetroxide, a distinct chemical entity. The residual category, 2822.00.00.90, encompasses all other cobalt oxides and hydroxides not specifically enumerated, ensuring comprehensive coverage within this classification.
