The Section 232 tariff will replace a narrower safeguard tariff on solar cells and modules that expired in February, the proclamation says. For covered products from Japan, South Korea, Taiwan, Switzerland, Liechtenstein and European Union members, the proclamation sets the combined total of the new duty and existing levies at 15%. Meanwhile, covered products from the United Kingdom would face a 10% tariff. The Commerce Secretary may adjust minimum import prices based on market conditions or other factors affecting the fair market value of covered products, per the proclamation. In January, the president signed a proclamation that imposed a 25% tariff on a narrow range of semiconductor imports, primarily advanced computing chips.
