The U.S. International Trade Commission has ruled that additional tariffs will be imposed on solar imports from Cambodia, Malaysia, Thailand, and Vietnam due to injury to the domestic solar industry. This follows a Commerce Department investigation that revealed extremely high subsidy rates for some exporters. The decision paves the way for updated tariff rates, which will affect crystalline silicon photovoltaic cells. Industry representatives express concern that these tariffs may increase costs for domestic manufacturers, underscoring the need for congressional support for the Inflation Reduction Act’s tax credits to bolster U.S. solar manufacturing.
