Vietnamese defendants included Sujia Steel Pipe Ltd Company, Vietnam Steel Pipe Company Limited and SeAH Steel Vina Corporation.
The plaintiff also noted that many other Vietnamese steel exporters have not been listed in the complaint yet.
The dumping margins on Vietnamese businesses are very high of 103.83%.
Earlier in 2011, the US initiated anti-dumping and countervailing duty investigations on imports of CWP from India, Oman, UAE and Vietnam. However, it ended as the DOC identified that Vietnamese businesses received no subsidy and the ITC concluded that there was no damage on the US CWP industry.
Thus, this is the second US anti-dumping investigation against Vietnamese CWP and the sixth one on Vietnamese steel this year.
The DOC will carry out investigations within 20 days since the official complaint is lodged.
The Vietnam Competition Authority warned that domestic CWP producers and exporters prepare all necessary things to cope with the lawsuit to protect their legitimate rights.
