Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If low ferrosilicon with <2% Mg
Base ferrosilicon grades under 65% silicon use different subheadings.
If ferrosilicomanganese composition
Silicomanganese ferroalloys have dedicated heading regardless of minor magnesium.
If pure silicon content emphasized
Silicon, even high-purity, without ferro characteristics goes to inorganic chemicals.

Import Tips & Compliance
• Submit weight-percentage assays from accredited labs; use steel drums for safe transport of reactive alloys; monitor anti-dumping duties on Chinese-origin ferrosilicon
