United States Steel Corp. announced its intention to challenge a recent determination by the U.S. International Trade Commission that revocation of an antidumping duty order on large-diameter welded line pipe from Mexico would not be likely to cause material injury to domestic producers.

U.S. Steel is appealing this decision to a bi-national dispute resolution panel to be convened under the terms of the North American Free Trade Agreement. U.S. Steel’s appeal will seek a reversal of the ITC’s determination and ask that the antidumping order on large-diameter line pipe from Mexico be reinstated. No timetable for briefing or decision in this appeal has yet been released.
