US delays anti-dumping ruling on Indian solar cells to September 2026
The US Department of Commerce has postponed its final determination in the anti-dumping investigation of crystalline silicon photovoltaic cells from India, moving the deadline from the original date to September 10, 2026. Provisional measures—which impose preliminary duties to prevent injury during the investigation—have been extended from four months to not more than six months. Exporters and importers of Indian solar cells face an extended period of uncertainty on final duty rates.

The U.S. Department of Commerce announced on May 20, 2026, that it is postponing the final determination in its less-than-fair-value (LTFV) investigation of crystalline silicon photovoltaic cells from India. The new deadline for the final determination is September 10, 2026.
"The U.S. Department of Commerce (Commerce) is postponing the deadline for issuing the final determination in the less-than-fair-value (LTFV) investigation of crystalline silicon photovoltaic cells, whether or not assembled into modules (solar cells) from India until September 10, 2026, and is extending the provisional measures from a four-month period to a period of not more than six months." — Federal Register, 20 May 2026
Provisional measures extended to six months
In addition to the postponement, Commerce has extended provisional anti-dumping measures from the original four-month period to a maximum of six months. Provisional measures refer to preliminary duties imposed during the investigation to prevent market disruption and material injury to domestic producers while Commerce completes its fact-finding.
Crystalline silicon photovoltaic cells (HS Chapter 85, specifically around 8541.40) are a critical input for solar panel manufacturing and solar energy systems. This investigation addresses allegations that Indian producers are selling these cells in the U.S. market at prices below fair value, in violation of trade remedy law.
Impact on importers and exporters
The extended investigation timeline means that importers of Indian solar cells, as well as U.S. solar manufacturers and project developers relying on these inputs, will face prolonged uncertainty on final duty rates. During the provisional period, importers must post bonds or deposits equal to the preliminary duty rate to secure clearance of shipments. The six-month extension gives Commerce additional time to gather evidence, conduct verification, and prepare its final analysis.
What this means for shippers
Importers of solar cells from India must budget for provisional duties through at least September 10, 2026, and prepare for final duty assessments immediately thereafter. Verify your HS classification and country-of-origin documentation now to avoid post-determination penalties. Update your landed-cost estimates and supply-chain contracts to account for the extended provisional period and potential final duties. /hs-codes/search
