The United States International Trade Commission (USITC) has ruled that imports of crystalline silicon photovoltaic (PV) cells, whether assembled into modules or not, from India, Indonesia, and Laos materially injured the domestic solar manufacturing industry.

Following the USITC’s affirmative determination, the Department of Commerce will issue antidumping and countervailing duty orders on November 2, 2026, on the covered solar products imported from India, Indonesia, and Laos.

The determination follows the US Department of Commerce’s September findings that solar products imported from the three countries were sold in the U.S. at less than fair value and benefited from government subsidies.

In its final affirmative determinations, Commerce finalized a dumping margin of 123.04% on Indian solar cell exporters. The companies include Mundra Solar PV, Mundra Solar Energy, Kowa Company, Premier Energies Photovoltaic, and all other unnamed exporters.

In the countervailing duty investigation, Commerce determined a subsidy rate of 126.09% for Mundra Solar Energy and Mundra Solar PV. It applied the same rate to all other Indian exporters and producers.

The USITC’s October 14 determination completes the injury assessment required for the imposition of the trade remedies.

The investigations followed petitions filed on July 17, 2025, by the Alliance for American Solar Manufacturing and Trade, comprising First Solar, Hanwha Q CELLS USA, and Mission Solar Energy.

The Department of Commerce initiated antidumping and countervailing duty investigations in August 2025 to examine the allegations.

In February 2026, Commerce announced preliminary affirmative countervailing duty determinations for solar imports from the three countries. For India, it assigned a preliminary subsidy rate of 125.87% to Mundra Solar Energy and Mundra Solar PV and applied the same rate to other exporters.

In April 2026, Commerce announced preliminary affirmative antidumping determinations. It assigned a dumping margin of 123.04% to Mundra Solar Energy and Mundra Solar PV.
