The United States produced some 430 thousand metric tons of silicon in 2018. Exports stood at some 12,000 metric tons of ferrosilicon and 41,000 metric tons of silicon metal. On the other hand, the U.S. imported some 158,000 metric tons of ferrosilicon and 118,000 metric tons of silicon metal. Russia is the leading exporter of silicon to the United States, accounting for 19 percent of total silicon imports between 2014 and 2017.
The consumption of silicon in the United States was 660,000 metric tons per year in 2018. Silicon is used in the production of steel, cast irons, superalloys, other alloys, and other unspecified categories. Interestingly, silicon is also the basis for omnipresent silicones - silicon-based polymers. As polysilicon—a particularly pure form of silicon—silicon is vital for the photovoltaic industry. Another important use of silicon is the use of highly refined silicon in electronics, often as semiconductors for discrete devices and integrated circuits.
