The US announced 15% tariffs on polysilicon products (a key semiconductor and solar panel input) with minimum import prices set for Dec 4, 2026—$21/kg for polysilicon, $100/kg for wafers, and $0.22–$0.38/watt for solar cells/modules. The tariff aims to boost US domestic production and reduce China's 96% market dominance. While industry backers see it as protecting US manufacturers, critics warn higher input costs could slow solar expansion and burden electronics consumers, with Korea's industry cautioning this may deter investment in US manufacturing.
