In the United States, domestic firms can file an anti-dumping petition under the regulations determined by the U.S. Department of Commerce, which determines "less than fair value" and the International Trade Commission, which determines "injury". These proceedings operate on a timetable governed by U.S. law. The Department of Commerce has regularly found that products have been sold at less than fair value in U.S. markets. If the domestic industry is able to establish that it is being injured by the dumping, then anti-dumping duties are imposed on goods imported from the dumpers' country at a percentage rate calculated to counteract the dumping margin.
