Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If other ferroalloys like ferrophosphorus
Ferroalloys not containing silicon primarily are classified under other ferroalloys subheadings.
If for lower grade with ≤55% silicon
Silicon content threshold determines specific ferrosilicon subheading versus 'other'.
If in slag form from processing
Ferrosilicon slag waste products fall under Chapter 26 slag and ash provisions.
