A number of US officials appealed to the Biden administration to raise import tariffs on Russian-origin ferrosilicon, mainly in order to stimulate domestic production in this way.

It was proposed to increase the import tariff rate on Russian ferrosilicon (75% Si) from the current 11.5% to 35%. This ferrosilicon is classified under HTSUS 7202.21.50.

US ferrosilicon producers Globe Specialty Metals and CC Metals and Alloys have invested more than US$10 million since October 2021 to expand their own production. Therefore, the demand will be met domestically in spite of Russia's supply interruptions.
