U.S. Sets 15% Polysilicon Tariff and Price Floors for Chip and Solar Supply Chains
The United States imposed a 15% tariff and minimum import prices on polysilicon and downstream products, including price floors of about $21 per kilogram for polysilicon and $0.38 per watt for solar modules, effective December 4.
Why it matters: Polysilicon policy now intersects directly with both domestic chip manufacturing and the power infrastructure required for large-scale AI deployment.
The United States is imposing new trade protections on imported polysilicon as Washington attempts to expand domestic supply chains for semiconductors and solar-power equipment.
The measures include a 15% tariff and minimum import prices on polysilicon and several downstream products. Reported price floors include approximately $21 per kilogram for polysilicon and $0.38 per watt for solar modules, with the protections scheduled to take effect December 4.
China dominates significant portions of the global polysilicon supply chain. That concentration matters to two technology markets undergoing major capital expansion: semiconductor manufacturing and electricity generation.
AI infrastructure increasingly depends on both. Data centers require advanced electronics while also driving demand for new generation capacity. The policy is intended to encourage domestic manufacturing, but higher minimum prices may also raise costs for companies that depend on imported material or downstream solar components.
