US President Donald Trump has signed an Executive Order imposing a 15 percent tariff on products made from polysilicon and setting minimum import prices on polysilicon and related products.
Key facts
- However, the order argued that imports of the material had impacted its production capacity in the US, with the country’s share of polysilicon production capacity falling from 50 percent in 2005
- US President Donald Trump has signed an Executive Order imposing a 15 percent tariff on products made from polysilicon and setting minimum import prices on polysilicon and related products
- Around 90 percent of the world’s polysilicon production originates in China
- In addition to imposing tariffs and minimum import prices, the US government will begin offering incentives to companies that invest in US production of polysilicon and polysilicon derivatives
Summary
Polysilicon is a high-purity form of silicon commonly used as a raw material in solar panels and semiconductors. The EO will come into effect on December 4, 2026. Tariffs are paid by the importer, not the exporter. The executive order said that, for decades, “America has allowed foreign countries to weaken United States producers in the polysilicon sector, eroding our economic and national security.”
