U.S. International Trade Commission Finds Solar Imports from India, Indonesia, and Laos Injure U.S. Manufacturers

On October 14, 2026, the U.S. International Trade Commission (ITC) released the result of its vote in the antidumping and countervailing duty investigation involving solar imports from India, Indonesia, and Laos. The ITC issued an affirmative final determination, finding that the domestic industry is materially injured or threatened with material injury by imports of cheap solar equipment from those three countries. 

As a result of the determination, the U.S. Department of Commerce will issue an antidumping order and a countervailing duty order in the next month on imports of solar equipment that fall within the scope of the investigation. Commerce previously set total duties ranging from 147% to 267% across the three countries.

The U.S. solar industry is also monitoring additional Trump administration actions that could affect import costs and supply chains. Beginning December 4, 2026, new Section 232 measures will impose a 15% tariff and minimum import prices on covered polysilicon products and derivatives, a key input for solar panels. These measures will stack on top of other applicable duties. Separately, Commerce is investigating whether solar products assembled in Ethiopia using Chinese components should be subject to existing duties on Chinese solar products.
