The Committee on Pipe and Tube Imports, a nonprofit organization for U.S. pipe and tube producers, approved a resolution calling on Congress to oppose extending Trade Promotion Authority unless the Bush Administration initiates Section 421 “investigations against injurious and surging pipe and tube imports from China.” The Committee said those imports have grown 20-fold from 100,000 tons in 2002 to 2.2 million tons in 2006.
