The US Department of Commerce (DOC) earlier, on June 20, based on petitions filed by DAK Americas LLC, Nan Ya Plastics Corporation and Augira Polymers had officially initiated the investigation on polyester fibre imported from Việtnam, China, India, the Republic of Korea and Taiwan.

DOC announced the termination of the anti-dumping investigation on polyester fibre imported from Việtnam.

The plaintiffs alleged that polyester staple fibre products were being shipped to the United States at prices lower than their normal value. In addition, the dumping had caused significant damage to the domestic industry due to price depression.

The scope of the investigation covers fine denier polyester staple fibre, not carded or combed, measuring less than 3.3 decitex in diameter, coded HS: 5503.20.0025.

According to the Ministry of Industry and Trade, Việtnam exported some 13,000 tonnes of fine denier polyester staple fibre worth an estimated US$12.4 million to the United States in 2016, ranking third behind China ($79.4 million) and India ($14.7 million).

The withdrawal of the lawsuit was requested only for Việtnam, and the investigation into products from China, India, the Republic of Korea and Taiwan (China) continues.
