WASHINGTON, D.C. — September 11, 2026 — The U.S. Commerce Department has finalized substantial anti-dumping and countervailing duties on solar cells and panels imported from India, Indonesia and Laos, concluding that producers in the three countries dumped products in the U.S. market and benefited from unfair government subsidies.

The Commerce Department assigned anti-dumping margins of 123.04% for Indian producers, 94.36% for Indonesian producers and 65.43% for Lao producers.

Additional countervailing duty rates were set at 126.09% for Indian producers, between 73.2% and 173.7% for Indonesian producers, and between 82.03% and 153.67% for Lao producers.

The trade investigation was initiated by the Alliance for American Solar Manufacturing and Trade, whose members include U.S. solar manufacturers First Solar, Hanwha Qcells and Mission Solar Energy.

The Alliance said the final determinations represent an important step toward enforcing U.S. trade laws and restoring competition for domestic solar manufacturers and workers.

The case will now move to the U.S. International Trade Commission (USITC), which is scheduled to issue its final determination on October 14 regarding whether imports from the three countries have materially injured, or threaten to injure, U.S. manufacturers.

If the USITC reaches an affirmative determination, the Commerce Department is expected to issue final duty orders in November 2026.

The latest action represents another major development in the U.S. solar trade dispute. The United States first imposed anti-dumping and countervailing duties on Chinese solar products in 2012, after which Chinese manufacturers increasingly shifted production capacity to other Asian markets.

The new duties on India, Indonesia and Laos could therefore have broader implications for global solar manufacturing and supply chains, potentially affecting sourcing strategies, production locations and the cost structure of PV projects entering the U.S. market.
