The US Department of Commerce Tuesday said it had imposed preliminary antidumping 

duties on polytetrafluoroethylene imports from China and India. 

"Commerce preliminarily determined that exporters from China and India have sold PTFE 

resin  in  the  United  States  at  69.34%  to  208.16%  and  18.49%  less  than  fair value, 

respectively," the department said. 

For China, Daikin Fluorochemicals had been assigned with an 84.75% duty, while Shando

ng Dongyue Polymer Material Co. faced 69.34%. Hangzhou Fine Fluorotech and Shanghai 

Huayi 3F New Materials Sales had been slapped with 78.74% each. Other than the named 

companies, a China-wide duty of 208.16% was imposed. 

For India, a duty of 18.49% was imposed on Gujarat Fluorochemicals and all other domestic 

producers and exporters. 

The Department of commerce will make a final determination on the antidumping duties on 

September 12. 

In 2016, the US received 3,057 mt of PTFE from China and 1,716 mt from India, valued at 

$24.6 million and $14.3 million, respectively, the US Census Bureau said. 

PTFE  is  used  in  the  production  of semiconductors, automotive components, electrical 

appliances and non-stick frying pans.
