In a major win for Chinese exporters, Jinlong Precision Copper Pipe Group, the world’s largest manufacturer of air-conditioning copper pipes, has been granted a "dumping margin of 0.00%" by the U.S. Department of Commerce. This marks the first time since 2010 that a Chinese company has successfully challenged the U.S. anti-dumping duties imposed on copper pipes from China and Mexico. The ruling means that Jinlong’s products are no longer considered to be sold below fair market value in the U.S., effectively removing the trade barrier.
According to the final administrative review released by the U.S. Department of Commerce on June 12, Jinlong did not engage in dumping practices when exporting seamless refined copper pipes to the U.S. between November 22, 2010, and October 31, 2011. As a result, the company’s subsidiaries in China and Mexico will no longer need to prepay anti-dumping duties on their exports. Additionally, approximately $11 million in previously paid duties will be refunded, providing significant financial relief.
Industry experts view this as a breakthrough for the Chinese copper industry, which has long struggled with U.S. anti-dumping measures. It signals a potential shift in how the U.S. approaches these trade barriers, offering hope for future relief. Wang Shizhong, vice president of Jinlong Group, highlighted the company’s competitive edge, emphasizing its advanced production technology and exclusive fittings supply chain. He noted that even U.S. manufacturers cannot replicate these innovations, making the American market reliant on Jinlong’s high-quality products.
The case began in 2009 when U.S. copper pipe manufacturers filed an anti-dumping complaint against imports from China and Mexico. In November 2010, the U.S. International Trade Commission ruled that Chinese and Mexican producers would face anti-dumping duties ranging from 11.25% to 60.85% for China and 24.89% to 31.43% for Mexico. Jinlong was the only company exempted from the highest rates, with a 11.26% duty, while the average rate for other Chinese manufacturers stood at around 30%. This latest ruling represents a turning point, demonstrating that Chinese companies can successfully defend themselves in U.S. trade disputes.
