The Trump administration has implemented a 15% tariff on polysilicon-based imports, effective December 4th. Polysilicon, a highly refined form of silicon, serves as a critical component in semiconductor and solar panel production. The move targets goods primarily sourced from China, which dominates global polysilicon manufacturing.
According to an executive order signed Thursday, the tariff aims to strengthen domestic US production capabilities in semiconductors and solar energy sectors. Officials argue the measure is necessary to maintain economic and national security standards while enabling American manufacturers to compete with Chinese competitors in artificial intelligence and renewable energy markets.
China’s foreign ministry criticized the decision, contending that the US has misused national security justifications to disadvantage Chinese businesses. A ministry spokesperson warned that protectionist policies would ultimately harm US competitiveness and disrupt commercial relationships between the two nations. The US currently operates two major polysilicon facilities: one in Michigan operated through a joint venture involving Corning and a Japanese partner, and another in Tennessee run by Munich-based Wacker Chemie. Both companies expressed support for the tariff, citing benefits for semiconductor supply chain resilience and national defense interests.
