This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product is a supported catalyst
Supported catalysts are classified in heading 38.15, not as pure chemicals.
If the powder is prepared as a pigment for enamels
Prepared pigments of Chapter 32 take precedence over chemically defined compounds.

Import Tips & Compliance
• Confirm the product is not a commercial grade cobalt oxide, as those may be classified elsewhere
• Provide a certificate of analysis to verify chemical purity
• If used as a catalyst, check if it is supported on a substrate, which may change classification

Battery-Grade Cobalt Tetroxide
Battery-grade cobalt tetroxide (Co3O4) is a high-purity, chemically defined cobalt oxide used as a precursor in lithium-cobalt-oxide cathodes for electric vehicle batteries. It meets Chapter 28's criteria for separate chemically defined compounds and is not excluded by the chapter's legal notes. This tariff item covers cobalt oxides and hydroxides, including commercial grades.
Co3O4 Catalyst Precursor for Chemical Synthesis
Calcined cobalt tetroxide used as a precursor for supported cobalt catalysts in Fischer-Tropsch synthesis is a chemically defined Co3O4. It falls under the tariff item as a cobalt oxide, meeting Chapter 28's criteria. The chapter notes do not exclude it, and it is not covered by other headings.
Cobalt Black Pigment (Co3O4)
Cobalt black pigment (Co3O4) with a spinel structure, used for ceramics and not meeting commercial grade specifications. It is a chemically defined cobalt oxide, classifiable under this tariff item as 'other' cobalt oxide.
Cobalt Green Oxide Pigment
Cobalt green oxide pigment is a cobalt zinc oxide (CoZnO) blend used as a green ceramic pigment. While it contains cobalt oxide, it is a mixture of metal oxides rather than a single chemically defined cobalt oxide or hydroxide. It may still qualify as a commercial cobalt oxide if the cobalt oxide content is predominant and it meets the heading's scope.
Cobalt Hydroxide (Co(OH)2)
Cobalt hydroxide (Co(OH)2) is a rose-colored powder used as a battery precursor and in metallurgy. It is a separate chemically defined compound of cobalt, explicitly covered by the tariff item's description of cobalt hydroxides. It meets Chapter 28's criteria for inorganic compounds and is not excluded by the chapter notes.
Cobaltic Hydroxide
Cobaltic hydroxide (Co(OH)3) is an unstable hydroxide used in specialty oxidants and research. It is a separate chemically defined compound of cobalt and falls under the tariff item's scope for cobalt hydroxides. Chapter 28's notes do not exclude this compound, and it is not covered by other headings.
