HS code for Manganese oxide: 2820.90

Manganese oxides, excluding manganese dioxide.

Classification of manganese oxide under HS 2820.90

Manganese oxides are classified under HS code 2820.90 as inorganic chemicals. While natural manganese oxides (ores) fall under Chapter 26, chemically produced or purified oxides are categorized in Chapter 28. Heading 2820 is specifically reserved for manganese oxides. It is subdivided into 2820.10 for manganese dioxide and 2820.90 for "other" oxides. This "other" category includes manganous oxide (MnO), manganese sesquioxide (Mn2O3), and trimanganese tetraoxide (Mn3O4). These substances are often used in industrial applications, such as the production of fertilizers, animal feed, or as precursors to other manganese compounds. The classification depends on the chemical purity and the manufacturing process; if the oxide is obtained by a chemical process or is a purified natural product, it belongs here. It is important to note that this code excludes manganese hydroxides, which are classified under heading 2825. The distinction between the dioxide and other oxides is vital for duty rates and regulatory controls in various jurisdictions.

  • Manganese(II) oxide as a fertilizer additive

Codes often confused with 2820.90

Common mistake. This code is often confused with 2820.10, which is strictly for Manganese Dioxide (MnO2). It is also frequently misclassified as 2602.00 (Manganese ore) if the importer fails to distinguish between a raw mineral and a chemically processed inorganic compound.

Top exporters and importers of HS 282090 (the code used for manganese oxide), 2025

In 2025, the largest exporter of HS 282090 (the code used for manganese oxide) in UN Comtrade data was India, with 16% of world exports; the largest importer in UN Comtrade data was Saudi Arabia, with 15% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

Figures cover everything classified under HS 282090, not only manganese oxide.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
