Washington, D.C. (April 23, 2026) – The U.S. Department of Commerce (DOC) made affirmative preliminary antidumping determinations (AD) in its investigations into crystalline silicon photovoltaic (CSPV) cells, whether or not assembled into modules, from India, Indonesia, and the Lao People’s Democratic Republic (Laos).
The preliminary determinations confirm that producers in these countries are dumping solar cells and modules into the U.S. market at unfairly low prices, undercutting American-made products and distorting market competition at a pivotal moment for the domestic manufacturing sector. As a result, preliminary antidumping duties will now be imposed, and cash deposits collected to offset the unfair pricing margins identified by Commerce.
The preliminary antidumping duty margins are 123.04% for all Indian producers, 35.15% for all Indonesian producers, and 22.46% for all Laotian producers.
Combined with the preliminary countervailing duty determinations, this means that the current AD/CVD rates are about 234% for India, 121% to 178% for Indonesia, and 103% for Laos.
The margins announced today represent the next step in a rigorous, multi-stage process that will continue to evolve as Commerce gathers additional data and completes its investigation. Today’s rates confirm that these countries were dumping solar imports in the U.S.
Since filing its petitions on July 17, 2025, the Alliance has advanced these cases through multiple stages of the U.S. trade remedy process. Following Commerce’s initiation of both AD and CVD investigations, the U.S. International Trade Commission voted affirmatively in its preliminary phase, finding a reasonable indication that unfairly traded imports are materially injuring the domestic industry.
Commerce’s affirmative preliminary subsidy and dumping determinations now confirm that producers in India, Indonesia, and Laos are benefiting from unfair government support and selling products into the U.S. market at unfairly low prices. Together, these findings reinforce the Alliance’s position that strong enforcement is essential to preserving the momentum of America’s solar manufacturing resurgence.
Key Upcoming Dates
- Final AD and CVD Determinations (Commerce): September 3, 2026
- Final Injury Determination (ITC): October 19, 2026
- Issuance of AD/CVD Orders: October 26, 2026
The Alliance looks forward to continuing to work with Commerce and the ITC throughout the remainder of this investigation to ensure that U.S. trade laws are fully enforced and that American solar manufacturing receives the level playing field it deserves.
The Alliance for American Solar Manufacturing and Trade is a coalition of four member and supporter companies calling for the enforcement of U.S. trade laws against foreign entities engaging in illegal practices to protect American jobs, ensure fair market prices, and secure a strong American solar manufacturing industry for generations to come.
