HS Code 2820.90 – Manganese oxides; excluding manganese dioxide
HS code 2820.90 is the 6-digit subheading for manganese oxides, excluding manganese dioxide. It is used for manganese(II,III) oxide, manganese(III) oxide, manganese(VII) oxide, manganese monoxide and manganese sesquioxide.
What HS 2820.90 covers
These manganese oxides, excluding the more common manganese dioxide (MnO2), represent a diverse group of inorganic compounds crucial for various industrial applications. In international trade, these materials are primarily exchanged between chemical manufacturers, metallurgical industries, and specialized producers of ceramics, glass, and batteries. Major importers include countries with robust steel production, chemical processing plants, and advanced manufacturing sectors, as manganese compounds are vital as alloying agents, catalysts, and pigments. Exporters are typically nations with significant manganese ore deposits and processing capabilities, or those with advanced chemical synthesis industries. Key things to know include their varying oxidation states, which dictate their specific uses, from powerful oxidizers to colorants. The purity and specific chemical form (e.g., Mn2O3, Mn3O4) are critical trade specifications, often impacting pricing and end-use suitability. Global demand is influenced by trends in steel production, renewable energy technologies (e.g., certain battery types), and the chemical industry's need for catalysts.

Codes often confused with 2820.90
Common mistake. This code is often confused with 282010 (Manganese dioxide) due to the general term "manganese oxides," but the exclusion is critical for proper classification. It might also be confused with manganese ores under Chapter 26 if not sufficiently processed.
Top exporters and importers of HS code 282090, 2025
In 2025, the largest exporter of HS code 282090 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.

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).
