The US Department of Commerce published preliminary affirmative antidumping duty (AD) determinations on April 23, 2026 (Federal Register publication April 28, 2026), finding that crystalline silicon photovoltaic cells (whether or not assembled into modules) from India, Indonesia, and Laos are being sold in the US at less than fair value. Preliminary dumping margins are 123.04% for India, 35.17% for Indonesia, and 22.46% for Laos, with Commerce ordering US Customs and Border Protection to begin collecting AD cash deposits at those rates (107.77% adjusted cash-deposit rate for India; 22.06% for Laos). This runs parallel to, and stacks on top of, the CVD case on the same merchandise and countries (see responds_to), meaning combined AD+CVD cash-deposit burdens on subject imports now exceed 100% for all three origins. Final AD determinations are due July 13, 2026 (India, Indonesia) and September 9, 2026 (Laos).

The US Department of Commerce published preliminary affirmative countervailing duty (CVD) determinations on February 26, 2026, finding that producers and exporters of crystalline silicon photovoltaic cells (whether or not assembled into modules) from India, Indonesia, and Laos received countervailable government subsidies. Preliminary subsidy rates are 125.87% for India; 85.99%–143.30% by individual Indonesian producer (104.38% all-others rate); and a uniform 80.67% for Laos. Commerce ordered US Customs and Border Protection to begin collecting cash deposits at these rates on subject imports pending a parallel antidumping investigation and final determinations later in 2026. The case originated from a petition filed in August 2025 by US crystalline silicon PV manufacturers.

The US Department of Commerce preliminarily determined that countervailable subsidies are being provided to producers and exporters of silicon metal from Laos, Australia, Norway, and Thailand, publishing four parallel preliminary affirmative CVD determinations on 2025-09-26 following an initiation on 2025-05-21 (petition by Ferroglobe USA, Inc. and Mississippi Silicon LLC). For Laos, Commerce set a preliminary countervailable-subsidy cash-deposit rate of 240.00% ad valorem for both the sole mandatory respondent, Lao Silicon Co., Ltd., and the all-others rate, based entirely on adverse facts available after finding the respondent did not cooperate. Companion CVD investigations against Australia, Norway, and Thailand were found affirmative the same day, each with its own preliminary subsidy-rate cash-deposit schedule. Commerce ordered CBP to suspend liquidation and require cash deposits at the indicated rates on covered entries from the Laos determination onward. Final CVD determinations are aligned with companion antidumping investigations on the same product.

The US Department of Commerce, following affirmative final less-than-fair-value determinations and an affirmative material-injury finding by the US International Trade Commission, issued antidumping duty orders on silicon metal from Angola and Laos, effective 2026-04-16. Commerce set a 68.45% ad valorem weighted-average dumping margin for Angola (both named respondents and the all-others rate) and a 94.44% margin for Laos, both based entirely on adverse facts available after the respondents did not cooperate with the investigation. The orders stem from an April 2025 petition by Ferroglobe USA, Inc. and companion less-than-fair-value investigations initiated 2025-05-21 that also covered Australia and Norway, where preliminary and final LTFV determinations followed on a later schedule.
