This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the product contains other manganese oxides mixed with MnO2
This sibling heading covers other manganese oxides, not pure manganese dioxide.
If the activated product is formulated with a carrier or promoter for specific catalytic use
Catalysts with added carriers may fall under prepared catalysts rather than a pure chemical.
