The United States Department of Commerce has imposed a preliminary duty of 126% on solar cells imported from India, creating fresh trade tensions between the two countries. The decision came into effect on February 24, 2026, after U.S. authorities concluded that Indian solar cell exports were benefiting from heavy government subsidies. According to Washington, these subsidies gave Indian manufacturers an unfair price advantage and affected the competitiveness of the domestic solar industry in the United States.
The investigation began in August 2025 following a petition by the Alliance for American Solar Manufacturing and Trade. The group claimed that rising imports of solar components from India, as well as from Indonesia and Laos, were putting pressure on American manufacturers. U.S. officials pointed to a sharp rise in Indian solar cell exports, which increased from 232 megawatts in 2022 to more than 2,200 megawatts in 2024. Authorities described this jump as substantial and said it justified closer scrutiny.
The preliminary tariff applies to most Indian exporters. However, U.S. officials specifically mentioned large Indian companies such as subsidiaries of the Adani Group, Premier Energies, and Waaree Energies. The Commerce Department stated that some firms did not fully cooperate during the investigation. As a result, it applied what it called “adverse facts available,” a method that can lead to higher duty rates when information is incomplete.
The move comes at a sensitive time. India and the United States had been discussing ways to ease trade barriers and strengthen economic ties. The newly announced duties are in addition to existing tariffs, making it more expensive for Indian solar products to enter the U.S. market. Since the United States is a key export destination for Indian solar manufacturers, the impact could be significant.
Industry in India are now evaluating the possible consequences. Some believe the immediate effect may be limited to the current quarter, as shipments already in transit may not be fully affected. However, many experts warn that such a steep duty will sharply raise prices for Indian solar cells in the American market, reducing their competitiveness.
The Commerce Department is expected to announce its final decision by July 2026. Separate anti-dumping investigations are also underway. Until a final ruling is issued, Indian solar exporters face uncertainty as they adjust to new trade challenges in one of their most important overseas markets.
