Since September 2009, the US government has imposed and renewed anti-dumping duties on tubes imported from China and Mexicao.
In a vote on November 15, 2016 the U.S. International Trade Commissionrenewed the existing anti-dumping duty orders on seamless refined copperpipe and tube from China and Mexico.
On September 30, 2009 four U.S. firms (Cerro Flow Products, Inc.; KobeWieland Copper Products, LLC; Mueller Copper Tube Products, Inc.; and Mueller Copper Tube Company, Inc.) filed anti-dumping petitions against imports of refined copper pipe and tube from China and Mexico. The Department of Commerce calculated dumping margins of 24.89-31.43% for Mexico and 11.25-60.85% for China in its final determinations, and the U.S. International Trade Commission reached final affirmative injury determinations on October 26, 2010. As a result, the anti-dumping orders were imposed.
The petitioners had estimated dumping margins of 60.6 percent for China and a range of 46.4-54.1 percent for Mexico. In the case of China this estimate is based on the use of India as a "surrogate" under the special methodology used for non-market economies. According to the petitioners, total U.S. imports of these products from China and Mexico were valued at $728.2 million in 2008.
