Technical Grade Manganese Dioxide
Technical grade manganese dioxide is used in the production of ferrites, ceramics, and pigments, with moderate purity levels suitable for industrial applications. It is imported under HTS 2820.10.00.00 as a chemically defined inorganic oxide of manganese. Synthetic production ensures uniformity over natural variants.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If incorporated into inorganic pigments
Finished inorganic coloring matters containing MnO2 are classified in Chapter 32, not raw oxides.
If antimony-doped for special ceramics
Doped metal oxides for electronics may shift to other oxide headings if composition changes.

Import Tips & Compliance
• Specify particle size distribution (e.g
• 1-10 microns) to match technical grade specs for customs
• Comply with dust emission standards during import by using sealed containers
• Monitor for Section 301 tariffs if sourced from China

Synthetic Manganese Dioxide (EMD)
Electrolytic Manganese Dioxide (EMD) is a high-purity synthetic form of manganese dioxide produced via electrolysis, used primarily as a cathode material in alkaline and zinc-carbon batteries. It falls under HTS 2820.10.00.00 as it is chemically defined manganese dioxide, distinct from natural ores. This powder form ensures consistent performance in dry cell batteries.
Battery Grade Manganese Dioxide Powder
High-purity manganese dioxide powder specifically formulated for use in primary battery cathodes, offering high discharge capacity and stability. Classified under HTS 2820.10.00.00 due to its chemical definition as MnO2 without other significant impurities. It is produced synthetically to meet rigorous electrochemical standards.
Activated Manganese Dioxide
Activated manganese dioxide is a porous form of MnO2 used as a catalyst in organic synthesis and water purification filters. It is classified in HTS 2820.10.00.00 as chemically defined manganese dioxide, activated through thermal or chemical treatment to increase surface area. This distinguishes it from natural pyrolusite.
