US Initiates Antidumping Investigation on Indian Solar Cells
The U.S. Department of Commerce has made a preliminary affirmative determination that crystalline silicon photovoltaic cells from India are being sold in the United States at less than fair value (LTFV), triggering an antidumping investigation covering July 2024–June 2025. This is the first step in a process that could result in antidumping duties on solar cells and modules imported from India. Shippers and importers should monitor this case closely, as duties could materially impact landed costs for solar equipment sourced from Indian manufacturers.

The U.S. Department of Commerce announced on April 28, 2026, a preliminary affirmative determination that crystalline silicon photovoltaic cells from India, whether assembled into modules or not, are being sold in the United States at less than fair value (LTFV). The investigation covers the period of July 1, 2024, through June 30, 2025.
What's Covered
The investigation applies to crystalline silicon photovoltaic cells and modules sourced from India. This broad scope covers both finished solar modules and the component cells that feed into downstream assembly and installation. The preliminary determination establishes that there is sufficient evidence of price undercutting to proceed with a formal antidumping investigation.
Preliminary and Critical Circumstances Findings
Commerce has made a preliminary affirmative determination not only of sales at less than fair value, but also of "critical circumstances" in part. This dual finding suggests that the agency believes there is a reasonable likelihood that suspension of liquidation (a freeze on final duties) would be circumvented unless duties are applied retroactively to a date before the formal investigation notice.
As stated in the Federal Register notice: "The U.S. Department of Commerce (Commerce) preliminarily determines that crystalline silicon photovoltaic cells, whether or not assembled into modules (solar cells) from India are being, or are likely to be, sold in the United States at less than fair value (LTFV)."
Next Steps and Comment Period
Interested parties—including Indian manufacturers, U.S. importers, solar installers, and competing U.S. producers—are invited to submit comments on the preliminary determination. The investigation will proceed toward a final determination, which typically occurs several months after the preliminary phase. If Commerce makes a final affirmative determination, the International Trade Commission (ITC) will conduct a separate injury investigation.
Impact on Tariff Classification and Landed Cost
The relevant HS chapter for solar cells is Chapter 85 (Electrical machinery and apparatus). Importers should verify that their specific products are correctly classified within this chapter and should prepare for potential antidumping duties that could be layered on top of existing tariff rates.
For shippers and freight forwarders, this investigation underscores the importance of tracking antidumping cases early and factoring preliminary duty estimates into landed cost calculations as the case develops.
What this means for shippers
Antidumping investigations can result in substantial duties applied retroactively. Monitor the progress of this case and revise your landed cost models to account for potential antidumping duties on Indian solar cells. Confirm HS classification and country of origin documentation now to avoid customs delays if duties are imposed.
