Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing over 30% magnesium
Higher magnesium ferrosilicon variants have separate statistical suffixes within the same heading.
If treated as carbide-based with magnesium
Magnesium-containing carbides classify under Chapter 28 inorganic chemicals, not ferroalloys.
If for ferrosilicomanganese with magnesium
Manganese-inclusive variants fall under ferrosilicomanganese regardless of magnesium addition.
