The Dept. of Commerce has released its final determinations in an antidumping/countervailing duty (AD/CVD) investigation on solar cell imports from India, Indonesia and Laos. The DOC determined that solar cell and panel producers and exporters from these countries have been dumping solar products into the U.S. market at unfairly low prices and have benefited from subsidies, causing injury to the domestic manufacturing industry.
A range of AD and CVD rates were determined:
India
| Exporter/Producer | Preliminary AD rate | Final AD rate |
| All exporters | 123.04% | 123.04% |
| Exporter/Producer | Preliminary CVD rate | Final CVD rate |
| All exporters | 125.87% | 126.09% |
Indonesia
| Exporter/Producer | Preliminary AD rate | Final AD rate |
| Blue Sky Solar (Elite Solar) | 94.36% | 94.36% |
| All others | 35.17% | 94.36% |
| Exporter/Producer | Preliminary CVD rate | Final CVD rate |
| Blue Sky Solar (Elite Solar) | 143.3% | 173.70% |
| PT REC Solar Indonesia (NE Solar) | 85.99% | 73.20% |
| All others | 104.38% | 73.20% |
*PT REC Solar Indonesia has no relation to REC Group, operating in Singapore.
Laos
| Exporter/Producer | Preliminary AD rate | Final AD rate |
| All exporters | 33.57% | 65.43% |
| Exporter/Producer | Preliminary CVD rate | Final CVD rate |
| Solarspace | 80.67% | 82.03% |
| Vietnam Sunergy (VSUN) | 80.67% | 153.67% |
| All others | 80.67% | 82.03% |
The Alliance for American Solar Manufacturing and Trade, a group of domestic solar manufacturers, petitioned the government in July 2025 for an AD/CVD investigation, alleging that solar panel manufacturers had relocated their operations to India, Indonesia and Laos to avoid tariffs placed on imports from Cambodia, Malaysia, Thailand and Vietnam. The U.S. International Trade Commission (ITC) determined in August 2025 that the U.S. industry has been materially injured by imports from the three countries, and Commerce has been performing its own investigation into the matter.
“America’s solar manufacturing sector is poised for a historic resurgence, with domestic module capacity up more than 750% since 2022 and cell production expanding as well,” said Tim Brightbill, co-chair of Wiley’s International Trade Practice and lead counsel to the Alliance. “But that progress is being harmed by dumped and subsidized imports from India, Indonesia and Laos that have denied American producers a level playing field. [These] final determinations are an essential step toward enforcing our trade laws and restoring fair competition for U.S. solar manufacturers and the workers they employ. We will keep monitoring import data and holding bad actors accountable wherever they move next.”
With Commerce releasing its final tariff amounts, they will only go into effect if the ITC issues an affirmative final decision. The ITC is scheduled to vote on the matter on Oct. 14, 2026.
The Alliance, which includes First Solar, Mission Solar, Qcells and Talon PV, participated in the ITC’s final hearing in this case earlier this month. Sixteen U.S. panel manufacturers provided details to the ITC about their operations: AMPS (JA Solar/Corning), Canadian Solar, Heliene, Hounen, Illuminate USA, Jinko, Mission Solar, PowerFilm, Qcells, Runergy, SEG, Silfab, Suniva, T1, Tesla and Waaree.
Only the Alliance provided comments to the ITC that were supportive of AD/CVD being placed on imports from India, Indonesia and Laos. Commentors discouraging tariffs and critical circumstances include:
- BYD: against tariffs in Indonesia
- Canadian Solar and SEG: against tariffs in Indonesia and Laos
- JA Solar: against tariffs in Indonesia
- Mundra (Adani): against tariffs in India
- Runergy: against tariffs in Indonesia
- Trina and Talesun: against tariffs in Indonesia
- Waaree: against tariffs in Indonesia (and asked the ITC to rely on corrected Indian import numbers)
- SEIA: against tariffs in all three countries
