The Committee on Pipe and Tube Imports has charged that Chinese pipe and tube producers are evading duties on their imports into the U.S., in some cases by falsifying the points of origin on the shipments. U.S. manufacturers have brought the allegations to the attention of U.S. Customs authorities. "They’re doing it mostly in standard pipe and we’ve seen it in some mechanical tubing but also energy and oil country tubular goods," said Barry Zekelman, CEO of John Maneely Co. "It’s really widespread."
