The inquiry is predicated upon a complaint filed by DAK Americas, Nan Ya Plastics and Augira Polymers. They accused that polyester staple fibre products have been shipped to the US at prices less than their normal value and dumping has caused significant damage to the domestic industry due to price depression and reduced profits and market shares and jobs.

The alleged anti-dumping duty margin for Vietnamese product is 64.73%.

Last year, Vietnam shipped around 12.4 million of polyester staple fibre to the US, ranking third behind China (US$79.4 million) and India (US$14.7 million).

DOC is to give a preliminary conclusion on the investigation in late November and anti-dumping duties will be imposed as from mid-March 2018 if any of damage is found.
