The US Department of Commerce has announced preliminary anti-dumping duties for imports of fine denier polyester staple fibre from China, India, South Korea, and Taiwan.   

According to its investigations, exporters of fine denier polyester staple fibre from the four countries were found to have sold it at less than fair value. The affirmative preliminary determinations in the anti-dumping investigations were issued on Tuesday (19 December).

As a result, the Commerce Department says it will instruct US Customs and Border Protection to collect cash deposits from importers of fine denier polyester staple fibre from China (52.66% to 170.92%), India (0.66% to 15.66%), Korea (0.00% to 45.23%), and Taiwan (0.00% to 48.86%) based on these preliminary rates.

“The US values its relationships with these nations, but all of our trading partners must play by the rules,” said US Secretary of Commerce Wilbur Ross. “We will continue to review all information related to this preliminary determination while standing up for American businesses and workers.”

In 2016, US imports of fine denier polyester staple fibre from China, India, Korea, and Taiwan were valued at an estimated US$79.4m, $14.7m, $10.6m, and $9.6m, respectively.

The anti-dumping and countervailable duty probe was launched in June in response to a petition filed by three major US synthetic fibre producers: DAK Americas, Nan Ya Plastics Corporation America, and Auriga Polymers Inc.
