Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If silicon content is 55% or less
Ferrosilicon with lower silicon levels falls under the specific subheading for low-silica ferrosilicon, changing the tariff rate.
If containing both silicon and manganese
Ferroalloys with significant manganese content are classified as ferrosilicon-manganese under a separate heading.
If chemically defined as a mixture for specific chemical use
Processed ferrosilicon mixtures for non-metallurgical chemical applications may fall under Chapter 38 inorganic chemicals.
