The Trump administration has announced the imposition of a 15% tariff rate and a minimum price on imports of products made from polysilicon, a critical raw material used in the production of solar panels and semiconductor chips [1]. This policy targets Chinese companies, which currently control 96% of global polysilicon production, underscoring China’s dominant position in the supply chain for both the solar and semiconductor industries [1].
According to the Semiconductor Industry Association, the solar industry is the primary consumer of polysilicon, while semiconductor chips accounted for 2.4% of annual polysilicon consumption in 2025 [1]. The new tariffs are part of a broader US strategy to push back against China’s dominance in the sector, aiming to protect domestic industries and reduce reliance on Chinese imports [1].
The measure is expected to have significant implications for both the solar and semiconductor markets, given polysilicon’s essential role in manufacturing photovoltaic cells and chips [1]. The announcement signals escalating trade tensions between the US and China, with potential disruptions to global supply chains in renewable energy and technology sectors [1].
CONCLUSION
The US’s decision to impose a 15% tariff on polysilicon imports marks a significant escalation in trade tensions with China and is likely to impact global supply chains in the solar and semiconductor industries. Market participants should prepare for potential disruptions and increased costs in these sectors as the new tariffs take effect.
