The Department of Commerce announced preliminary anti-dumping duties on utility-scale wind towers from China and Vietnam July 27. The preliminary duties add to countervailing duties of between 13.74 and 26 percent announced in May. The initial findings from the Department’s dumping investigation allege that Chinese and Vietnamese producers/exporters have dumped utility-scale wind towers in the United States at margins of 20.85 percent to 72.69 percent and 52.67 percent to 59.91 percent respectively. The agency and the U.S. International Trade Commission will review the tariffs before finalizing them later this year.
