Under heading 7202, ferrochromium with more than 4% carbon by weight is classified as high-carbon (720241), while ferrochromium containing 4% carbon or less is classified as low-carbon (720249). The carbon threshold reflects the metallurgical distinction between grades used in stainless steelmaking versus specialty low-carbon applications.

Yes, several ferroalloy products — including certain ferrosilicon and ferrovanadium grades — have been subject to antidumping or countervailing duty orders from specific countries at various times. Importers should check the current scope of any orders with CBP and the International Trade Administration before importing, as the applicable measure is line- and origin-specific.
