The US Department of Commerce has set preliminary antidumping duties up to 123.04%, the highest for India, followed by Indonesia and Laos
Some Indian exporters face a 107.77% cash deposit rate based on adverse inference due to incomplete data
The move follows earlier CVDs (up to 143%) and stems from AASMT claims of underpriced imports
The US Department of Commerce (DOC) has announced preliminary antidumping duties (ADDs) of up to 123.04% on solar imports from India, Indonesia, and Laos.
The highest tariff rate of 123.04% has been determined for solar imports from India, 35.17% on imports from Indonesia, and 22.46% on imports from Laos.
The DOC’s factsheet specifically identifies Mundra Solar PV Limited, Mundra Solar Energy Limited, Kowa Company Ltd, and Premier Energies Photovoltaic Private Limited among Indian exporters for the estimated weighted-average dumping margin. These companies must pay an advance cash deposit of 107.77%, assuming adverse inference in the absence of complete information from the companies.
For Laos-based companies listed in the factsheet, the ADD comes with a cash deposit rate of 22.06%. PT Blue Sky Solar Indonesia and PT REC Solar Energy Indonesia are among the companies listed in the factsheet for the ADD.
This follows preliminary countervailing duties (CVDs) – as high as 143% – announced by the DOC in February 2026 on exporters from these countries (see India, Indonesia, Laos Solar Imports Face High US CVD Rates).
Tariffs were imposed after the Alliance for American Solar Manufacturing and Trade petitioned the DOC to investigate solar cell and module imports from Laos, Indonesia, and India, alleging that Chinese-linked firms and Indian exporters were selling at low prices and undercutting the US market (see US Investigates Solar Trade From Laos, Indonesia & India).
According to the DOC, the US received over $792 million of solar imports from India in 2024, up from $760.7 million in 2023 and $83.8 million in 2022. Imports from Indonesia totaled $415 million in 2024, up from $171.9 million the previous year.
Solar imports from Laos rose from nothing in 2022 to $0.0067 million in 2023 to $335.7 million in 2024.
Recently, in an exclusive interview with TaiyangNews, National Solar Energy Federation of India (NSEFI) CEO Subrahmanyam Pulipaka said that Indian manufacturers are already diversifying their export destinations, exploring not just the Middle East, Africa, Latin America, and Europe but also Southeast Asia, East Asia, Oceania, and island nations (see NSEFI Exclusive: India Will Be World’s 2nd-Largest Solar Market In 2026).
As next steps, the DOC will issue final determinations in the AD investigations of solar cells from India and Indonesia around July 13, 2026, while the announcement for Laos will be made around September 9, 2026. Final determinations into both AD and CVD investigations are expected on October 19, 2026.
Meanwhile, AASMT law firm Wiley Rein LLP recently cautioned that solar developers and manufacturers in the US could face growing compliance risks linked to the use of imported blue wafers in solar cell production. The situation could expose projects to trade duties and threaten eligibility for US clean-energy tax credits (see Wiley: Blue Wafer Imports Could Raise US Solar Compliance Risk).
