U.S. Finalizes Trade Duties on PV Cells from India, Indonesia and Laos

The U.S. Department of Commerce announced final anti-dumping and countervailing duty determinations on September 11, 2026, covering crystalline silicon photovoltaic cells imported from India, Indonesia and Laos, whether or not assembled into modules.

High Anti-Dumping Margins

The final anti-dumping margins were set at:

• India: 123.04%, with a 107.17% adjusted cash deposit rate after subsidy offsets
• Indonesia: 94.36%
• Laos: 65.43%, with a 65.03% adjusted rate after subsidy offsets

Additional countervailing duties were also imposed, with rates varying by producer and exporter. Some Indonesian and Lao companies received particularly high subsidy rates.

Investigation Timeline

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

The final decision covers products under U.S. tariff codes 8541.42.0010 and 8541.43.0010.

Impact on the U.S. Solar Supply Chain

The decision adds another layer of trade-related costs for solar cells sourced from the three countries. Importers, manufacturers and module suppliers may need to reassess sourcing strategies and supply-chain costs as the U.S. continues to adjust its solar trade framework.
