The U.S. Department of Commerce announced its preliminary affirmative determinations in the anti-dumping duty investigations of crystalline photovoltaic cells, whether or not assembled into modules, from Cambodia, Malaysia, Thailand, and Vietnam. This move follows investigations stemming from concerns that manufacturers in these countries benefit from unfair government subsidies.

Here are the preliminary dumping rates determined by the Department of Commerce for companies in each country:

In June, the United States International Trade Commission decided to proceed with investigations into the alleged dumping of crystalline silicon photovoltaic cells from these Southeast Asian countries.

The Commission concluded that there was a reasonable indication that these imports, allegedly sold in the U.S. at unfairly low prices and subsidized by their respective governments, were causing material injury to the U.S. industry. It also found a reasonable indication that the U.S. industry is threatened with material injury because of subsidized imports of crystalline silicon photovoltaic cells from Cambodia.

The Commerce Department recently announced its preliminary affirmative determinations in the countervailing duty investigations of crystalline photovoltaic cells, whether or not assembled into modules from these countries.

The U.S. solar industry has experienced a significant surge in imports from Cambodia, Malaysia, Thailand, and Vietnam over the past three years. Imports from Cambodia rose from 799 million watts in 2021 ($218 million) to 6.72 billion watts ($2.31 billion) in 2023.

Malaysian imports grew from 6.19 billion watts ($1.67 billion) in 2021 to 6.76 billion watts ($1.87 billion) in 2023. Thailand’s imports increased from 4.3 billion watts ($1.13 billion) in 2021 to 10.6 billion watts ($3.73 billion) in 2023. Vietnam followed a similar trajectory, with imports rising from 5.34 billion watts ($1.31 billion) in 2021 to 12.3 billion watts ($3.99 billion) in 2023.

The U.S. International Trade Commission (ITC) made a preliminary determination in June this year.

The Commerce Department’s final determination is expected by February 10, 2025, while the ITC’s is scheduled for March 27, 2025. Should both bodies find that unfair subsidies were indeed granted, the final orders will be issued on April 3, 2025.
