President Donald Trump signed an executive order on August 6, 2026, imposing a 15% tariff and minimum import prices on polysilicon products, effective this December.
The measure aims to protect US manufacturers, whose share of global polysilicon production dropped from 50% in 2005 to less than 2% in 2024, amid intense competition from China.
The Chinese embassy in Washington criticized the move as an abuse of state power that disrupts trade, while the US government plans to offer incentives to boost domestic production.
