The US DOC has finalized separate AD/CVD rates for solar imports from India, Indonesia, and Laos
The measures require a positive final injury determination from the ITC to come into effect
The ITC decision, if supporting the DOC decision, will be followed by the latter issuing AD/CVD by November 2, 2026
The US Department of Commerce (DOC) has finalized antidumping and countervailing duties (AD/CVD) on solar imports from India, Indonesia, and Laos. Final rates vary significantly across the three countries.
In its investigation, the DOC found that crystalline silicon PV (CSPV) solar cells and modules from the three countries were sold in the US at unfairly low prices and benefited from countervailable subsidies. The Department states this caused material injury to the domestic solar manufacturing industry.
The final rates vary by country. According to the DOC factsheet, the Department has set an AD margin of 123.04% and a CVD rate of 126.09% for India. For Indonesia, the final dumping margin is 94.36%, while the CVD rates range from 73.2% to 173.7%. For Laos, the dumping margin is set at 65.43%, while CVD rates range from 82.03% to 153.67%.
Among the Indian manufacturers, the DOC has specifically named Mundra Solar PV Limited, Mundra Solar Energy Limited, Kowa Company Ltd., and Premier Energies Photovoltaic Private Limited. Companies identified in the Laos investigation include Solarspace Technology (Laos), JA Solar Vietnam, and Trina Solar Science & Technology (Thailand), among others.
The DOC’s final decision follows an investigation launched in August 2025 in response to a petition by the Alliance for American Solar Manufacturing and Trade (AASMT) concerning solar cell and module imports from the three countries. In April 2026, the department announced preliminary antidumping duties (ADDs) of up to 123.04% on the imports (see US: Up To 123% ADD On Solar Imports From India, Laos, Indonesia).
AASMT’s Lead Counsel and Co-Chair of Wiley’s International Trade Practice Tim Brightbill welcomed the DOC decision, calling it an essential step towards restoring fair competition for US solar manufacturers.
“Today's final determinations are an essential step toward enforcing our trade laws and restoring fair competition for U.S. solar manufacturers and the workers they employ,” said Brightbill.
The final imposition of duties, however, still depends on the International Trade Commission (ITC) making its final injury determination, expected on October 14, 2026. If the commission finds that the US industry has been materially injured or faces a threat of material injury from the imports, the DOC will issue the AD/CVD orders on November 2, 2026.
The determinations are part of a broader trade enforcement effort by US solar manufacturers seeking action against imports they say have harmed domestic production.
The original AD/CVD orders, known as Solar I, were imposed on Chinese CSPV products in December 2012. Claiming that Chinese producers shifted production to Cambodia, Malaysia, Thailand, and Vietnam to circumvent the duties, the US administration issued new AD/CVD orders, known as Solar III, in June 2025. According to the Alliance, imports from those four countries fell from $12.2 billion in 2023 to $1.3 billion in 2025 following the trade actions (see USITC Issues Final Injury Determination In AD/CVD Investigation).
US solar manufacturers filed the Solar IV petitions against India, Indonesia, and Laos in July 2025. The latest announcement moves the three-country case closer to a final outcome, pending the ITC's October injury vote.
Supported by these actions, US solar module manufacturing has expanded way beyond the actual demand – 66 GW DC of nameplate module capacity against annual installation projections of 44 GW DC (see US Solar Installations Rebound 45% YoY To 11.4 GW DC In Q2 2026).
Nevertheless, the US now sources solar cells from other geographies, such as Ethiopia, which is now the subject of a new AD/CVD petition filed by the AASMT. The alliance claims manufacturers are importing solar cells and modules assembled in Ethiopia using Chinese-origin components (see New US Petition Targets Ethiopia Solar Imports).
The trade dispute is unlikely to end with these three countries (Indonesia, India, and Laos), as Brightbill said the group would continue monitoring import data and holding ‘bad actors accountable wherever they move next’.
Meanwhile, the US administration continues to restrict solar imports through broader trade measures, including a 15% tariff on imported polysilicon derivatives and a minimum import price (MIP) for polysilicon products entering the US (see US Announces 15% Tariff On Imported Polysilicon Under Section 232).
Separately, a coalition of Canadian Solar, SEG Solar, and Heliene – called American Manufacturers for Energy Resilience (AMER) – has petitioned the DOC to investigate solar cell imports from South Korea, including from Hanwha Qcells, which is a part of the AASMTC (see Waaree Hit By US Duties; South Korea AD/CVD Probe Sought).
