Trump imposes 15% tariff on polysilicon to curb China's market dominance

The Trump administration has announced a 15% tariff on polysilicon, a critical material used in semiconductor and solar panel manufacturing. The measure is designed to counter China's dominant position in global polysilicon production, where Chinese producers currently hold a near-monopoly. The tariff is part of broader U.S. efforts to reduce dependence on Chinese supply chains for strategically important materials. By raising import costs, Washington aims to incentivize domestic or allied-nation production of the key chip material.
