Product classification
HS code for Manganese dioxide: 2820.10
Manganese dioxide.
Classification of manganese dioxide under HS 2820.10
Manganese dioxide is classified under HS code 2820.10. This product is an inorganic chemical compound with the formula MnO2. Chapter 28 of the Harmonized System covers inorganic chemicals, precious metals, and rare-earth metals. Heading 2820 is specifically designated for manganese oxides. Subheading 2820.10 is reserved for manganese dioxide, which is the most commercially significant oxide of manganese due to its use as a cathode material in alkaline and lithium-ion batteries. This classification applies to both natural manganese dioxide that has been chemically treated (such as electrolytic manganese dioxide or EMD) and synthetic versions produced through chemical precipitation. It is distinguished from manganese ores, which are raw mineral products classified in Chapter 26. The high level of chemical purity and the specific manufacturing process (electrolysis or chemical synthesis) are the primary factors that place this product in Chapter 28 rather than the mining chapters.

Codes often confused with 2820.10
Common mistake. Manganese dioxide is often confused with HS code 2602.00, which covers natural manganese ores and concentrates. The distinction is that 2602.00 is for raw minerals, while 2820.10 is for chemically pure or processed oxides. It may also be confused with 2820.90, which covers other manganese oxides such as manganese oxide (MnO) or mangano-manganic oxide (Mn3O4).
Top exporters and importers of HS 282010 (the code used for manganese dioxide), 2025
In 2025, the largest exporter of HS 282010 (the code used for manganese dioxide) in UN Comtrade data was China, with 45% of world exports; the largest importer in UN Comtrade data was Indonesia, with 19% 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 282010, not only manganese dioxide.

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).
