Ternium requests postponement in coated steel trade case

Ternium Mexico wants the Commerce Department to delay making its final decision in the ongoing corrosion-resistant steel dumping investigation.
US petitioners, however, think the company has already been granted enough extensions and shouldn’t be allowed anymore.
On March 10, legal representatives for Ternium requested that Commerce extend its deadline for completing the anti-dumping investigation to the maximum allowed by law, 135 days after the preliminary determination. The request would bump the final decision until Aug. 16.
Commerce’s preliminary AD decision is currently due April 3. On that date, provisional duties will begin to be collected on subject imports. The deadline for Commerce’s final determination is June 17.
The company has also asked “that the department extend the application of provision measures by a corresponding period of extension.”
On March 11, counsel for petitioners U.S. Steel, Wheeling-Nippon Steel, Steel Dynamics Inc., and the United Steelworkers requested Commerce deny any more of Ternium’s postponement requests.
They point out the department has already granted the Mexican steelmaker numerous extensions amounting to nearly two months.
“Petitioners respectfully submit that the calculation of a fair and accurate dumping margin in this investigation requires that Ternium be held to existing reporting deadlines, as it has already been given all the extra time that it could possibly expect (and more),” the petitioner’s legal counsel wrote.
Coated trade case update
US mills and the United Steelworkers are seeking anti-dumping duties on coated sheet imports from Australia, Brazil, Canada, Mexico, the Netherlands, South Africa, Taiwan, the United Arab Emirates, and Vietnam.
Additionally, they want countervailing duties (CVDs) placed on subsidized coated imports from Brazil, Canada, Mexico, and Taiwan.
The US government began investigating the imports in September.
Commerce issued preliminary CVDs last month, and Customs has begun collecting the duties of 1-140% on coated imports from those four countries.
US mills have alleged critical circumstances exist for South Africa and the UAE. If Commerce confirms the allegations, AD duties on CORE from the two nations will be applied retroactively to Jan. 3.
The Commerce Department is scheduled to release preliminary AD duties on April 3, and final AD and CVD margins on June 17. The International Trade Commission (ITC) is slated to make the final injury determinations by Aug. 1.
Editor’s note: This story has been updated to correctly state Wheeling-Nippon Steel as a petitioner, not Nippon Steel.
