Commerce ups Vietnam’s dumping margins in coated trade case
Written by Laura Miller

The US Department of Commerce has upwardly revised the preliminary anti-dumping margins for Vietnam in the ongoing trade case investigating coated flat-rolled steel (CORE) imports.
In April, Commerce released initial anti-dumping margins for all 10 countries under investigation. At the time, the agency assigned Vietnamese CORE producers dumping margins of 39%-88%.
Days later, however, domestic petitioners in the case pointed out “significant ministerial errors” in Commerce’s calculations, according to a filing published this week in the Federal Register.
Recall those petitioners include Steel Dynamics Inc. (SDI), Nucor, U.S. Steel, Wheeling-Nippon Steel, and the United Steelworkers union.
Commerce looked into the petitioners’ claims and found them to be accurate. It therefore amended the estimated dumping margins, ultimately assigning higher rates to all Vietnamese companies (see below).
Exporter/producer | Previous preliminary AD margin | Recalculated preliminary AD margin |
---|---|---|
Hoa Sen Group | 59.00% | 132.10% |
Ton Dong A Corporation | 39.84% | 51.64% |
China Steel and Nippon Steel Viet Nam Joint Stock Company | 49.42% | 91.87% |
Hoa Phat Steel Sheet Limited Liability Company | 49.42% | 91.87% |
Maruichi Sun Steel Joint Stock Company | 49.42% | 91.87% |
Tay Nam Steel Manufacturing & Trading Co., Ltd | 49.42% | 91.87% |
TVP Steel Trading Joint Stock Company | 49.42% | 91.87% |
Viet Phap Steel Corrugated Joint Stock Company | 49.42% | 91.87% |
Vietnam-Wide Entity | 88.12% | 178.89% |
Commerce noted the cash deposit rate for the Vietnam-wide entity will be adjusted for subsidy offsets, resulting in a cash deposit rate of 136.57%.
This sprawling trade case is expected to wrap up later this year, with Commerce set to issue final duty determinations on Aug. 26. The International Trade Commission will then make final injury rulings in early October.
