HS Code for Manganese dioxide

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.

Products Included

• Electrolytic manganese dioxide (EMD)
• Chemical manganese dioxide (CMD)
• Synthetic manganese dioxide for battery manufacture
• Manganese dioxide used as a glass decolorizer
• Activated manganese dioxide for catalysts

Common Misclassification

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).

FAQ

What is the HS code for manganese dioxide?
