Heading 2820

Manganese oxides

2 declarable lines

Heading 2820 covers manganese oxides as separate chemically defined inorganic compounds. It has two declarable lines: manganese dioxide in 2820.10.00.00, and all other manganese oxides in 2820.90.00.00. Both lines carry the same general (MFN) rate of 4.7%.

Products in this heading

  • Manganese dioxide (MnO2) powder
  • Electrolytic manganese dioxide for battery cathodes
  • Natural manganese dioxide, pyrolusite ore
  • Manganous oxide (manganese monoxide, MnO)
  • Manganese sesquioxide (Mn2O3)
  • Manganese oxide used as a glass and ceramic colorant
  • Manganese oxide feed additive for livestock

How to choose the right subheading

  • Whether the compound is manganese dioxide (MnO2) or another manganese oxide
  • The chemical formula and oxidation state of the manganese in the product
  • Whether the goods are a separate chemically defined inorganic compound rather than a mixture or preparation
  • Whether the product is a finished article or a preparation that puts it in a later chapter

Often confused with

  • Iron oxides and earth colors

    Iron oxide is a separate oxide covered by its own heading, not a manganese compound.

    Heading 2821
  • Chromium oxides and hydroxides

    Chromium oxides are classified in 2819 regardless of similar industrial use.

    Heading 2819
  • Lead oxides, red lead and orange lead

    Lead-based oxides go to 2824, not to the manganese oxide heading.

    Heading 2824
  • Aluminum oxide and aluminum hydroxide

    Alumina products are named in 2818.

    Heading 2818
  • Zinc oxide and other metal oxides not named elsewhere

    Other metal oxides fall in the residual heading 2825.

Frequently asked questions

What is the HTS code for manganese dioxide?

Manganese dioxide is classified under 2820.10.00.00. The general (MFN) duty rate for that line is 4.7%.

What is the duty on manganese dioxide?

The general (MFN) rate for 2820.10.00.00 is 4.7%. Manganese dioxide is the only line in heading 2820 that covers that specific oxide.

How do I classify other manganese oxides such as manganous oxide?

Manganese oxides other than manganese dioxide go under 2820.90.00.00. The general (MFN) duty rate for that line is 4.7%, the same as the dioxide line.
