Commerce Finalizes Antidumping and Countervailing Duties on Solar Imports from Southeast Asia
Year-long case results in high tariffs for Chinese-owned companies harming the U.S. solar manufacturing industry
Washington, D.C. — The U.S. Department of Commerce has issued final affirmative determinations in its antidumping (AD) and countervailing duty (CVD) investigations concerning crystalline silicon photovoltaic (CSPV) cells and modules imported from Cambodia, Malaysia, Thailand, and Vietnam. These determinations confirm that producers and exporters from these nations have been dumping solar products into the U.S. market at unfairly low prices and have benefited from countervailable subsidies, causing material injury to the domestic solar manufacturing industry.
Final Determinations in the AD and CVD Solar III cases:
Cambodia: Dumping margins up to 125.37%; CVD rates up to 3,403.96%.
Malaysia: Dumping margins up to 81.24%; CVD rates up to 168.80%.
Thailand: Dumping margins up to 202.90%; CVD rates up to 799.55%.
Vietnam: Dumping margins up to 271.28%; CVD rates up to 542.64%.
“On behalf of the American Alliance for Solar Manufacturing Trade Committee and its members, we would like to commend the Commerce Department for its extremely hard work on these important investigations over the last year. This is a decisive victory for American manufacturing and confirms what we’ve long known: that Chinese-headquartered solar companies have been cheating the system, undercutting U.S. companies, and costing American workers their livelihoods,” said Tim Brightbill, co-chair of Wiley’s International Trade Practice and lead counsel to the Alliance. “Enforcing our trade laws isn’t just a legal matter—it’s essential to rebuilding our industrial base, securing our energy independence, and protecting American jobs.”
These duty rates are set to take effect following the U.S. International Trade Commission’s (ITC) final injury determination, expected on May 20, 2025. If the ITC affirms that the U.S. industry is materially injured or threatened by these imports, the Department of Commerce will issue AD and CVD orders, enforcing duties on imports from the four countries.
The investigations were initiated in response to petitions filed on April 24, 2024, by the American Alliance for Solar Manufacturing Trade Committee—a coalition of U.S. solar manufacturers including Convalt Energy, First Solar, Meyer Burger, Mission Solar, Qcells, REC Silicon, and Swift Solar, and Talon PV. The coalition, represented by Wiley Rein LLP, sought relief from unfair trade practices that have undermined the U.S. solar manufacturing sector.
