Commerce Department Finds Dumping of Solar Products from China and Taiwan Likely to Continue if Duties End
Estimated reading time: 4–6 minutes
On February 10, 2026, the U.S. Department of Commerce released the final results of its expedited second sunset reviews of the antidumping duty (AD) orders on certain crystalline silicon photovoltaic products from China and Taiwan.
Commerce determined that ending the AD orders would likely lead to continued or repeated dumping of solar products from both countries.
These findings cover crystalline silicon photovoltaic products—commonly known as solar products.
The original antidumping duty orders for these products were issued on February 18, 2015.
On August 1, 2025, Commerce announced it was starting the second round of five-year sunset reviews under section 751(c) of the Tariff Act of 1930.
Commerce received notices of intent to participate in the review on August 15, 2025, from the American Alliance for Solar Manufacturing. The American Alliance includes five U.S. producers: First Solar, Inc., Hanwha Q CELLS USA, Inc., Heliene USA Inc., Suniva, Inc., and Mission Solar Energy LLC.
According to their notice, the American Alliance qualifies as a domestic interested party under section 771(9)(E) of the Act.
On August 22, 2025, Commerce informed the U.S. International Trade Commission (ITC) that it had received valid notices of intent to participate.
On September 2, 2025, the American Alliance submitted substantive responses to Commerce.
No foreign producers or exporters responded with substantive submissions. Therefore, Commerce proceeded with a 120-day expedited sunset review.
Because of a federal government shutdown and related delays, Commerce extended all deadlines in the review. A total of 68 days of tolling was applied—47 days announced on November 14, 2025, and an additional 21 days announced on November 24, 2025.
The final result was issued on February 5, 2026.
Commerce concluded that ending the AD orders would likely lead to continued or renewed dumping.
The dumping margins likely to return if the orders are lifted are calculated as follows:
- Up to 165.04 percent for China
- Up to 27.55 percent for Taiwan
A full explanation of these results and the analysis behind them is included in the Issues and Decision Memorandum, which is publicly available through the ACCESS system at https://access.trade.gov.
The memorandum includes:
- A summary of the review
- Background of the orders
- Description of the products covered
- History of the review
- Legal analysis
- Findings on likelihood of dumping
- Likely dumping margins
- Final results
- Commerce’s recommendation
This is the final step in this sunset review under sections 751(c), 752(c), and 777(i)(1) of the Tariff Act of 1930, as well as under regulations 19 CFR 351.218 and 19 CFR 351.221(c)(5)(ii).
