NEW YORK — U.S. Steel Corp. and Wheatland Tube Co. have appealed the final determination in an anti-dumping duty investigation by the Commerce Department’s International Trade Administration (ITA) on circular welded carbon-quality steel pipe from China.

The ITA had amended its margins—to 45.35 percent from 69.2 percent for specific producers/exporters and the China-wide rate to 68.24 percent from 85.55 percent—following a ruling by the World Trade Organization’s Dispute Settlement Body.
