New Antidumping Duty and Countervailing Duty Petitions on PFA from India

At a Glance

• The Chemours Company FC, LLC filed antidumping and countervailing duty petitions on Perfluoroalkoxy Alkane (PFA) from India.
• Investigations related to these petitions could result in increased prices and/or decreased supply of PFA.
• The US Department of Commerce is expected to begin investigations on August 25, 2026.

On August 5, 2026, The Chemours Company FC, LLC. (Chemours) filed antidumping (AD) and countervailing duty (CVD) petitions on Perfluoroalkoxy Alkane (PFA) from India. PFA is a chemical used in a range of applications, including semiconductor fabrication, oil and gas chemical processing, pharmaceutical manufacturing, medical device production, laboratory equipment, food processing, high performance wire and cable, electrical insulation, and aerospace.

The US AD law imposes special tariffs to counteract imports that are sold in the United States at less than “normal value.” The US CVD law imposes special tariffs to counteract imports that are sold in the United States with the benefit of foreign government subsidies. For AD/CVD duties to be imposed, the US government must determine not only that dumping and/or subsidization is occurring, but also that there is “material injury” (or threat thereof) by reason of the dumped and/or subsidized imports. Importers are liable for any potential AD/CVD duties imposed. In addition, these investigations could impact purchasers by increasing prices and/or decreasing supply of PFA.

Proposed Product Scope

Please note that this section was not written by our authors but is taken verbatim from the petition.

The merchandise covered by these investigations is perfluoroalkoxy alkane (“PFA”), a copolymer of tetrafluoroethylene and perfluoroalkoxy side chains. Its chemical structure is represented as a repeating chain of tetrafluoroethylene units with perfluoroalkoxy side chains (-(CF₂-CF₂)_n-(CF₂-CF(OR_f))_m-) where R_f is a perfluorinated alkyl group (e.g., -CF₃,-C₂F₅, -C₃F₇). PFA is normally associated with Chemical Abstracts Service (“CAS”) registry number 26655-00-5 or 31784-04-0.

The scope includes PFA resin provided in primary forms (including, but not limited to pellets, granules, powder, flakes, or aqueous dispersions). PFA has a minimum melting endotherm peak temperature of 265 degrees Celsius and a melt flow rate of greater than 1 g/10 min.

The scope also includes merchandise matching the above description that has been finished, packaged, or otherwise processed in a third country, including by packaging with another product, or any other finishing, packaging, or processing that would not otherwise remove the merchandise from the scope of the investigation. The scope also includes PFA that is commingled or blended with PFA from sources not subject to the investigations. Only the subject component of such commingled products is covered by the scope of these investigations.

Excluded from the scope of these investigations is PFA that has a minimum melting endotherm peak temperature of less than 265°C and a melt flow rate of less than 1 g/10 min.

Also excluded from the scope of these investigations are PFA products compounded with fillers or reinforcing materials, including, but not limited to, glass fiber, carbon fiber, carbon black, graphite, mineral fillers, or similar reinforcing additives. This exclusion does not apply to unfilled PFA resin containing only minor processing aids, stabilizers, pigments, or other non-reinforcing additives.

The subject merchandise is currently properly classifiable under the Harmonized Tariff Schedule of the United States (“HTSUS”) subheading 3904.69.50. Products subject to these petitions may also enter under HTSUS subheadings 3904.61.00 and 3904.69.1000. Although the HTSUS subheadings are provided for convenience and customs purposes, the written description of the scope of the investigations is dispositive.

Estimated Dumping Margins

Chemours alleges dumping margins ranging from 47.93% to 56.57%.

Chemours also alleges subsidies with respect to subject imports from India, although the CVD petition does not quantify the alleged net subsidy margin.
