Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as part of magnesium alloy production set
End-use in magnesium manufacture might shift to Chapter 81 other base metals.
If considered carbides precursor
Certain reactive silicides could be reclassified under inorganic compounds.
If with manganese impurities
Manganese content above trace levels requires ferrosiliconmanganese classification.
