The tariff and minimum price floors are likely to raise costs for U.S. importers of polysilicon and derivatives, potentially increasing prices for semiconductors and solar panels. U.S. producers may benefit from reduced competition, while Chinese exporters face higher barriers, and South Korean chipmakers may see increased costs for U.S. operations.

On August 6, 2026, U.S. President Donald Trump signed a proclamation imposing a 15% tariff on imports of polysilicon derivative products, effective December 4, 2026. The action, taken under Section 232 of the Trade Expansion Act of 1962, also establishes minimum import prices for polysilicon and its derivatives: $21 per kilogram for polysilicon, $100 per kilogram for ingots and wafers, $0.22 per watt for solar cells, and $0.38 per watt for solar modules. The measure aims to protect U.S. polysilicon manufacturing, which is critical for semiconductor and solar panel production, and to counter alleged dumping by China. The proclamation follows a Section 232 investigation launched by the U.S. Department of Commerce in July 2025. Officials, including Commerce Secretary Howard Lutnick and United States — White House Staff Secretary William Scharf, emphasized the goal of onshoring supply chains and preventing foreign actors from undermining U.S. industry. South Korea's semiconductor industry is closely monitoring the impact on its U.S. operations.
