Cobalt oxides and hydroxides; commercial cobalt oxides
2 declarable lines
Heading 2822 covers cobalt oxides and cobalt hydroxides, including commercial cobalt oxides sold as powders and pigments. It has two declarable lines: one for cobalt(II, III) oxide (cobalt tetroxide) and one residual line for all other cobalt oxides and hydroxides. Both lines carry the same general (MFN) rate of 0.1%.
Products in this heading
- Cobalt(II, III) oxide powder (cobalt tetroxide)
- Cobalt(II) oxide (cobaltous oxide) powder
- Cobalt(III) oxide (cobaltic oxide)
- Cobalt hydroxide powder for battery precursor use
- Commercial cobalt oxide pigment for ceramics and glass
- Cobalt oxide for catalyst preparation
- Cobalt hydroxide paste for plating and chemical synthesis
How to choose the right subheading
- Confirm the product is a cobalt oxide or cobalt hydroxide, not a cobalt salt such as a sulfate, chloride or carbonate.
- Check whether the chemical form is cobalt(II, III) oxide (cobalt tetroxide), which takes the specific line 2822.00.00.10.
- Place all other cobalt oxides and cobalt hydroxides, including commercial grades, in the residual line 2822.00.00.90.
- Confirm the cobalt is not combined with other metals into a complex oxide or oxometalate salt, which is classified elsewhere.
Often confused with
- Heading 2833Cobalt sulfate
Cobalt sulfate is a sulfate salt, classified in the sulfates heading, not as an oxide.
- Heading 2827Cobalt chloride
Cobalt chloride is a halide and falls in the chlorides heading.
- Heading 2836Cobalt carbonate
Cobalt carbonate is a carbonate salt, covered by the carbonates heading.
- Heading 8105Unwrought cobalt metal and cobalt mattes
Metallic cobalt and cobalt metallurgy products sit in chapter 81, not chapter 28.
- Heading 2825Nickel oxides
Oxides of metals other than cobalt are classified as other metal oxides.
Frequently asked questions
What is the HTS code for cobalt tetroxide?
Cobalt(II, III) oxide, also called cobalt tetroxide, is classified under 2822.00.00.10 with a general (MFN) rate of 0.1%.
What is the duty on cobalt hydroxide?
Cobalt hydroxide falls under the residual line 2822.00.00.90, which carries a general (MFN) rate of 0.1%.
How do I classify cobalt oxide powder?
If the powder is cobalt(II, III) oxide, use 2822.00.00.10. Other cobalt oxides go in 2822.00.00.90. Both lines have a general (MFN) rate of 0.1%.
