U.S. Imposes Over 200% Solar Duties on Indian Imports

The United States Department of Commerce announced preliminary anti-dumping duties on solar cells and panels imported from India, Indonesia, and Laos in late April 2026. The agency assigned a dumping margin of 123.04% for India, 35.17% for Indonesia, and 22.46% for Laos. These measures follow a petition by the Alliance for American Solar Manufacturing and Trade, which alleged that low-priced imports were undercutting the U.S. manufacturing sector.

For India, these rates combine with countervailing duties announced in February 2026 to create a total tariff burden of approximately 234%. The department specifically cited critical circumstances for Mundra Solar Energy, Mundra Solar PV, Kowa, and Premier Energies, allowing duties to apply to shipments sent up to 90 days prior to the order. U.S. Customs and Border Protection now requires importers to post cash deposits based on these preliminary rates.

Indian industry bodies, including the National Solar Energy Federation of India and the Indian Solar Manufacturers Association, condemned the findings as fundamentally flawed and stated their intent to contest the ruling. Final determinations for India and Indonesia are scheduled for July 13, 2026, and for Laos around September 9, 2026. The United States International Trade Commission will issue a final injury determination on October 19, 2026, to decide if imports caused material injury to the domestic industry.
