U.S. imports of lower-purity silicon (under 99.99% by weight) (HS 280469) totaled $48.0M in April 2026, traded with 16 countries.
Last updated: April 2026 dataMetallurgical-grade silicon โ the dominant form under this heading โ is a primary alloying agent for aluminum castings in automotive and aerospace applications and a feedstock for silicone chemicals and solar-grade polysilicon upgrading. The US schedule distinguishes silicon between 99% and 99.99% pure (2804691000) from silicon below 99% purity (2804695000), with the latter representing the bulk of metallurgical-grade trade. Brazil leads US import supply, followed by Canada and Norway, all of which operate large electric-arc furnace smelting operations.

Metallurgical-grade silicon (typically below 99% purity) is classified under 2804695000 and is used primarily as an alloying element in aluminum production, as a raw material for silicone polymers, and as a precursor in polysilicon manufacturing. It is distinct from the higher-purity grades used directly in semiconductor or solar applications.
Brazil is the leading supplier, followed by Canada and Norway. Australia and Malaysia also contribute meaningfully. These countries host large electric-arc furnace smelters that produce silicon from quartz and carbon reductants at industrial scale.
