The US Department of Commerce has placed preliminary duties on imports of polytetrafluoroethylene (PTFE) resin from China and India as it begins an anti-dumping investigation.

US Secretary of Commerce Wilbur Ross announced the preliminary determinations of its anti-dumping duty investigations of imports of PTFE at prices far below market value following a petition by chemical firm The Chemours Company.

"The dumping of goods below market value in the United States is something the Trump Administration takes very seriously," said Secretary Ross. "The Department of Commerce will continue to stand up for American workers and business's in order to ensure that everyone trades on a level playing field."

On a preliminary investigation, the Commerce Department found exporters from China and India to have sold PTFE resin in the US at 69.34% to 208.16% and 18.49% less than fair value, respectively.

The Department says it will instruct US Customs and Border Protection (CBP) to collect cash deposits from importers of imports of PTFE resin from China and India based on these preliminary rates.

In 2016, imports of PTFE resin from China and India were valued at an estimated US$24.6m and $14.3m, respectively. 

Since Donald Trump took office, the US Commerce Department has initiated 112 new anti-dumping and countervailing duty investigations. This is 75% more than the 64 initiations in the last 466 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 unfair pricing of imports into the United States. Commerce currently maintains 430 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 is scheduled to announce the final determinations in these investigations on 18 September.
