PVTIME – Following an anti-dumping (AD) investigation into crystalline silicon photovoltaic (CSPV) cells imported from India, Indonesia and Laos, the US Department of Commerce has issued a preliminary affirmative determination. Preliminary dumping margins stand at 123.04% for all imports from India, regardless of whether the cells are assembled into modules, 35.15% for all producers in Indonesia, and 22.46% for Laos.
Combined with earlier preliminary countervailing duty (CVD) rulings, the total preliminary AD/CVD rates are approximately 234% for India, 121–178% for Indonesia, and 103% for Laos. The Department confirmed that enterprise-specific rates are based on available facts and adverse inferences. Indian firms, including Mundra Solar PV, Mundra Solar Energy, Premier Energy Photovoltaic and Kowa Company, face an adjusted cash deposit rate of 107.77%.
In Indonesia, the Department identified companies such as PT Blue Sky Solar Indonesia and PT REC Solar Energy Indonesia, which have an estimated average dumping margin of 35.17%. Laos has a weighted average dumping margin of 22.46%, resulting in a cash deposit rate of 22.06%.
Final determinations for India and Indonesia are expected in July 2026, with Laos’s final ruling due in September 2026. The final AD/CVD determinations and the U.S. International Trade Commission’s final injury ruling are projected for September and October 2026, respectively. AD/CVD orders are expected to follow in October 2026.
Premier Energies’ Chief Commercial Officer, Vinay Rustagi, told PV Tech that the tariffs would have a minimal impact. He noted that India’s module exports had already fallen significantly over the past year due to US tariff threats, and that further incremental effects would be negligible.
Solarium co-founder Nikhil Bansal noted that, although the Indian manufacturer does not directly target the US market, such developments would affect global supply chains and price dynamics. He added that India is in a difficult position, as export-focused manufacturers are facing short-term challenges, but have a stronger case for expanding domestic capacity under initiatives such as ‘Make in India’.
The investigation was prompted by a petition filed in August 2025 by the Alliance for American Solar Manufacturing and Trade, whose members include the US manufacturers First Solar, Hanwha QCells USA, and Mission Solar Energy. The Alliance claims that dumped and subsidised imports harm US manufacturing, a claim supported by the International Trade Commission’s finding of reasonable indications of material injury to the US industry.
The Department also noted that it had imposed preliminary CVDs of up to 125.87% on Indian CSPV cells in February.
