Trump administration to impose 15% tariff in polysilicon probe meant to counter China

The United States Trade Representative announced on Monday that a 15% tariff will be applied to imports of polysilicon from China, a move tied to an ongoing anti‑dumping investigation. Polysilicon, a key raw material for photovoltaic panels, has seen a surge in Chinese shipments to the U.S., prompting officials to claim that the pricing undercuts domestic producers and threatens jobs. The probe, launched in 2022, examines whether Chinese exporters receive subsidies that allow them to sell below fair market value. If the investigation confirms dumping, the tariff could become permanent. U.S. solar manufacturers such as First Solar and SunPower have welcomed the step, saying it could restore competitive balance and encourage investment in local production facilities. Chinese firms and trade groups warned that the duty will raise costs for solar developers, potentially slowing the rollout of renewable projects and inviting retaliation in other sectors. The tariff will take effect 30 days after publication in the Federal Register, and the administration said it will monitor market impacts while remaining open to adjustments.
