Summary

The U.S. Department of Commerce's ITA extended by 20 days the deadline for determining whether to initiate antidumping and countervailing duty investigations on imports of lithium hexafluorophosphate from China. The new initiation determination deadline is April 14, 2026. The extension is due to insufficient clarity regarding industry support for the petitions filed by Mexichem Fluor Inc. dba Orbia Fluor & Energy Materials.

What changed

Commerce received petitions on March 5, 2026, from Mexichem Fluor Inc. dba Orbia Fluor & Energy Materials requesting antidumping and countervailing duties on lithium hexafluorophosphate from China. Under the Tariff Act of 1930, Commerce must determine whether the petition has industry support (at least 25% of domestic production and more than 50% among supporters) within 20 days of filing. Because the industry support criteria are unclear, Commerce is exercising its authority under sections 702(c)(1)(B) and 732(c)(1)(B) to extend the determination deadline by an additional 20 days.

Importers and exporters of lithium hexafluorophosphate from China should monitor this proceeding closely, as initiation of formal investigations could lead to imposition of antidumping and/or countervailing duties. The extended initiation determination deadline is April 14, 2026. Interested parties should be prepared to submit information regarding industry support or opposition to the petitions if contacted by Commerce.

What to do next

  1. Monitor the ITA proceeding for the initiation determination due April 14, 2026
  2. Prepare documentation regarding industry support or opposition to the petitions
  3. Assess potential impact of AD/CVD duties on LiPF6 supply chains from China

Extension of Initiation of Investigations

The Petitions

On March 5, 2026, the U.S. Department of Commerce (Commerce) received antidumping and countervailing duty petitions on imports
of lithium hexafluorophosphate (LiPF 6) from the People's Republic of China (China), filed by Mexichem Fluor Inc. dba Orbia Fluor & Energy Materials (the petitioner). (1)

Determination of Industry Support for the Petitions

Sections 702(b)(1) and 732(b)(1) of the Tariff Act of 1930, as amended (the Act), require that a petition be filed by or on
behalf of the domestic industry. To determine that the petition has been filed by or on behalf of the industry, sections 702(c)(4)(A)
and 732(c)(4)(A) of the Act require that the domestic producers or workers who support the petition account for: (i) at least
25 percent of the total production of the domestic like product; and (ii) more than 50 percent of the production of the domestic
like product produced by that portion of the industry expressing support for, or opposition to, the petition. Moreover, sections
702(c)(4)(D) and 732(c)(4)(D) of the Act provide that, if the petition does not establish support of domestic producers or
workers accounting for more than 50 percent of the total production of the domestic like product, Commerce shall: (i) poll
the industry or rely on other information in order to determine if there is support for

     the petition, as required by subparagraph (A); or (ii) if there is a large number of producers, determine industry support
     using a statistically valid sampling method to poll the industry.

Extension of Time

Sections 702(c)(1)(A) and 732(c)(1)(A) of the Act provide that within 20 days of the filing of an antidumping or countervailing
duty petition, Commerce will determine, inter alia, whether the petition has been filed by or on behalf of the U.S. industry producing the domestic like product. Sections 702(c)(1)(B)
and 732(c)(1)(B) of the Act provide that the deadline for the initiation determination, in exceptional circumstances, may
be extended by 20 days in any case in which Commerce must “poll or otherwise determine support for the petition by the industry.”
Because it is unclear whether the industry support criteria have been met, Commerce has determined it should extend the time
period for determining whether to initiate the investigations in order to further examine the issue of industry support.

Commerce will need additional time to gather and analyze additional information regarding industry support. Therefore, it
is necessary to extend the deadline for determining the adequacy of the Petitions by an additional 20 days. As a result, in
accordance with sections 702(c)(1)B) and 732(c)(1)(B) of the Act, Commerce's initiation determination will now be due no later
than April 14, 2026.

International Trade Commission Notification

Commerce will contact the U.S. International Trade Commission (ITC) and will make this extension notice available to the ITC.
