HS Code 2820 — Manganese Oxides

Manganese oxides are inorganic compounds used primarily in the production of dry-cell batteries and as decolourising agents in glass making. Manganese dioxide is the most commercially significant member of this group, appearing as a black powder or grey metallic solid. It is also a catalyst in chemical synthesis.

What's included

Manganese dioxide
Manganous oxide
Manganic oxide
Electrolytic manganese dioxide (EMD)

What's excluded

Natural manganese dioxide (pyrolusite) → use 2602 (Natural ores are classified by their mineral state in Chapter 26.)

Common examples

EMD for alkaline batteries
Chemical manganese dioxide (CMD)
Manganese oxide for animal feed
Manganese sesquioxide

Frequently asked questions

How do you distinguish between natural and synthetic manganese dioxide?

Natural pyrolusite is HS 2602; synthetic versions produced via electrolysis or chemical precipitation are 2820.
