The US Department of Commerce has resolved to impose anti-dumping tariffs on fine denier polyester staple fibre suppliers in China, India, Korea and Taiwan.

The affirmative final determination follows an investigation into whether the four Asian nations were selling the product in the US market at unfairly low prices.

In 2017, imports of fine denier polyester staple fibre from China, India, Korea, and Taiwan were valued at an estimated $61.4m, $23.7m, $11.9m, and $7.4m, respectively.

The Commerce Department determined that exporters from the four countries sold fine denier polyester staple fibre in the US at less than fair value. As such, the tariffs imposed on China range between 65.2%-103.1%, while Korean importers can expect a tariff of 45.2%. India exporters were given a flat rate of 21.4%, and Taiwan up to 48.9%.

The US Government launched the investigation after DAK Americas, Auriga Polymers Inc., and Nan Ya Plastics Corp., America filed a petition in March 2017.

Since President Donald Trump took office, the US Commerce Department has initiated 114 new anti-dumping and countervailing duty investigations. This is 78% more than the 64 initiations in the last 489 days of the previous administration, it claims.

"The AD law provides US businesses and workers with an internationally accepted mechanism to seek relief from the harmful effects of the unfair pricing of imports into the United States. Commerce currently maintains 440 anti-dumping and countervailing duty orders which provide relief to American companies and industries impacted by unfair trade," it said in a statement.

The Department says it will now instruct US Customs and Border Protection to collect cash deposits from importers of fine denier polyester staple fibre from China, India, Korea, and Taiwan based on the final rates.
