The Alliance for American Solar Manufacturing and Trade has requested a 50-day postponement of the preliminary antidumping duty determination for solar cells and panels from India, Indonesia, and Laos, according to a report from Solar Power World. The request follows a U.S. International Trade Commission determination in August that the U.S. industry had been materially injured by imports from those three countries.
The Alliance, represented by Tim Brightbill and Wiley Rein LLP, stated the extension is necessary due to the complexity of the investigations covering multiple countries and because numerous outstanding supplemental questionnaires remain. If granted, this extension could push the preliminary antidumping determination release to April 21, 2026. There does not appear to be an extension requested for the countervailing duty determination, which may still be released around February 20.
American panel manufacturers first requested the investigation in July 2025, alleging that solar panel manufacturers had relocated operations to India, Indonesia, and Laos to avoid tariffs on imports from Cambodia, Malaysia, Thailand, and Vietnam. While imports from India have been relatively steady, data shows imports from Indonesia and Laos have increased significantly since 2024.
The Alliance, which includes First Solar, Mission Solar, Qcells, and Talon PV, escalated efforts on January 26 by filing a “critical circumstances” allegation with Secretary of Commerce Howard Lutnick. The document states that imports from India, Indonesia, and Laos have surged, activity that “strongly indicates that these imports are being rushed into the United States in an effort to avoid the imposition of antidumping and countervailing duties.”
The Alliance is asking the Department of Commerce to expedite a critical-circumstances decision by the preliminary countervailing duty determination date of February 20. Such a determination would impose duties retroactively on imports entered up to 90 days before tariffs are announced. This could place retroactive tariffs on the 2.4 GW of solar panels and 1.4 GW of cells from Indonesia that entered the United States in November 2025, plus imports from India and Laos.
During a 2024 investigation into solar imports from Southeast Asia, the Alliance also filed a critical circumstances allegation after observing an import increase from Vietnam and Thailand. The Department of Commerce agreed at that time and ordered retroactive duties on all cells and panels imported from Vietnam and Thailand, except from JA Solar and JinkoSolar.
The original schedule for tariff announcements was delayed by a 43-day government shutdown in October and November. The solar industry is expected to have a clearer picture on tariffs for imports from India, Indonesia, and Laos in the coming months.
