U.S. Finalizes Trade Duties on Solar Cells From India, Indonesia And Laos

The U.S. Department of Commerce has finalized anti-dumping and countervailing duty determinations on crystalline silicon photovoltaic cells from India, Indonesia and Laos, whether or not assembled into modules.

High Final Duty Margins

The final anti-dumping margins are 123.04% for India, 94.36% for Indonesia and 65.43% for Laos. After subsidy offsets, the adjusted rates for India and Laos are 107.17% and 65.03%, respectively.

Additional countervailing duties vary by company. Notably, some Indonesian and Lao producers face subsidy rates above 150%, while India’s major producers and other exporters face a 126.09% countervailing duty rate.

Investigation Concludes

The U.S. launched the investigation in August 2025, followed by preliminary countervailing duty determinations in February 2026 and preliminary anti-dumping determinations in April.

The final decision covers crystalline silicon PV cells under U.S. tariff classifications 8541.42.0010 and 8541.43.0010.

Impact on Solar Supply Chains

The measures significantly increase the potential import costs of covered solar cells from the three countries. The decision is expected to influence sourcing strategies and supply-chain planning for companies supplying the U.S. solar market, particularly those using Southeast Asian and Indian manufacturing bases.
