SUPPLEMENTARY INFORMATION:

The Petition

On August 5, 2026, the U.S. Department of Commerce (Commerce) received an antidumping duty (AD) petition concerning imports of perfluoroalkoxy alkane (PFA) from India, filed in proper form on behalf of The Chemours Company FC, LLC (the petitioner), a domestic producer of PFA.^[1] The AD Petition was accompanied by a countervailing duty (CVD) petition concerning imports of PFA from India.^[2]

Between August 11 and 24, 2026, Commerce requested supplemental information pertaining to certain aspects of the Petition in supplemental questionnaires.^[3] Between August 14 and ( printed page 56117) 25, 2026, the petitioner filed timely responses to these requests for additional information.^[4]

In accordance with section 732(b) of the Tariff Act of 1930, as amended (the Act), the petitioner alleges that imports of PFA from India are being, or are likely to be, sold in the United States at less than fair value (LTFV) within the meaning of section 731 of the Act, and that imports of such products are materially injuring, or threatening material injury to, the PFA industry in the United States. Consistent with section 732(b)(1) of the Act, the Petition was accompanied by information reasonably available to the petitioner supporting its allegations.

Commerce finds that the petitioner filed the Petition on behalf of the domestic industry, because the petitioner is an interested party, as defined in section 771(9)(C) of the Act. Commerce also finds that the petitioner demonstrated sufficient industry support for the initiation of the requested LTFV investigation.^[5]

Period of Investigation (POI)

Because the Petition was filed on August 5, 2026, pursuant to 19 CFR 351.204(b)(1), the POI for the India LTFV investigation is July 1, 2025, through June 30, 2026.

Scope of the Investigation

The product covered by this investigation is PFA from India. For a full description of the scope of this investigation, see the appendix to this notice.

Comments on the Scope of the Investigation

Between August 11 and 24, 2026, Commerce requested information and clarification from the petitioner regarding the proposed scope to ensure that the scope language in the Petition is an accurate reflection of the products for which the domestic industry is seeking relief.^[6] Between August 14 and 25, 2026, the petitioner provided clarifications and revised the scope.^[7] The description of merchandise covered by this investigation, as described in the appendix to this notice, reflects these clarifications.

As discussed in the Preamble to Commerce's regulations, we are setting aside a period for interested parties to raise issues regarding product coverage ( i.e., scope).^[8] Commerce will consider all scope comments received from interested parties and, if necessary, will consult with interested parties prior to the issuance of the preliminary determination. If scope comments include factual information, all such factual information should be limited to public information.^[9] Commerce requests that interested parties provide at the beginning of their scope comments a public executive summary for each comment or issue raised in their submission. Commerce further requests that interested parties limit their public executive summary of each comment or issue to no more than 450 words, not including citations. Commerce intends to use the public executive summaries as the basis of the comment summaries included in the analysis of scope comments. To facilitate preparation of its questionnaires, Commerce requests that scope comments be submitted by 5:00 p.m. Eastern Time (ET) on September 14, 2026, which is 20 calendar days from the signature date of this notice. Any rebuttal comments, which may include factual information and should also be limited to public information, must be filed by 5:00 p.m. ET on September 24, 2026, which is 10 calendar days from the initial comment deadline.

Commerce requests that any factual information that parties consider relevant to the scope of this investigation be submitted during that period. However, if a party subsequently finds that additional factual information pertaining to the scope of the investigation may be relevant, the party must contact Commerce and request permission to submit the additional information. All scope comments must be filed simultaneously on the records of the concurrent LTFV and CVD investigations.

Filing Requirements

All submissions to Commerce must be filed electronically via Enforcement and Compliance's Antidumping Duty and Countervailing Duty Centralized Electronic Service System (ACCESS), unless an exception applies.^[10] An electronically filed document must be received successfully in its entirety by the time and date it is due.

Comments on Product Characteristics

Commerce is providing interested parties an opportunity to comment on the appropriate physical characteristics of PFA to be reported in response to Commerce's AD questionnaires. This information will be used to identify the key physical characteristics of the subject merchandise in order to report the relevant cost of production (COP) accurately, as well as to develop appropriate product comparison criteria.

Interested parties may provide any information or comments that they feel are relevant to the development of an accurate list of physical characteristics. Specifically, they may provide comments as to which characteristics are appropriate to use as: (1) general product characteristics; and (2) product comparison criteria. We note that it is not always appropriate to use all product characteristics as product comparison criteria. We base product comparison criteria on meaningful commercial differences among products. In other words, although there may be some physical product characteristics ( printed page 56118) utilized by manufacturers to describe PFA, it may be that only a select few product characteristics take into account commercially meaningful physical characteristics. In addition, interested parties may comment on the order in which the physical characteristics should be used in matching products. Generally, Commerce attempts to list the most important physical characteristics first and the least important characteristics last.

In order to consider the suggestions of interested parties in developing and issuing the AD questionnaires, all product characteristics comments must be filed by 5:00 p.m. ET on September 14, 2026, which is 20 calendar days from the signature date of this notice. Any rebuttal comments must be filed by 5:00 p.m. ET on September 24, 2026, which is 10 calendar days from the initial comment deadline. All comments and submissions to Commerce must be filed electronically using ACCESS, as explained above, on the record of the LTFV investigation.

Determination of Industry Support for the Petition

Section 732(b)(1) of the Act requires that a petition be filed on behalf of the domestic industry. Section 732(c)(4)(A) of the Act provides that a petition meets this requirement if 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, section 732(c)(4)(D) of the Act provides 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) determine industry support using a statistically valid sampling method to poll the “industry.”

Section 771(4)(A) of the Act defines the “industry” as the producers as a whole of a domestic like product. Thus, to determine whether a petition has the requisite industry support, the statute directs Commerce to look to producers and workers who produce the domestic like product. The U.S. International Trade Commission (ITC), which is responsible for determining whether “the domestic industry” has been injured, must also determine what constitutes a domestic like product in order to define the industry. While both Commerce and the ITC apply the same statutory definition regarding the domestic like product,^[11] they do so for different purposes and pursuant to a separate and distinct authority. In addition, Commerce's determination is subject to limitations of time and information. Although this may result in different definitions of the like product, such differences do not render the decision of either agency contrary to law.^[12]

Section 771(10) of the Act defines the domestic like product as “a product which is like, or in the absence of like, most similar in characteristics and uses with, the article subject to an investigation under this title.” Thus, the reference point from which the domestic like product analysis begins is “the article subject to an investigation” ( i.e., the class or kind of merchandise to be investigated, which normally will be the scope as defined in the petition).

With regard to the domestic like product, the petitioner does not offer a definition of the domestic like product distinct from the scope of the investigation.^[13] Based on our analysis of the information submitted on the record, we have determined that PFA, as defined in the scope, constitutes a single domestic like product, and we have analyzed industry support in terms of that domestic like product.^[14]

In determining whether the petitioner has standing under section 732(c)(4)(A) of the Act, we considered the industry support data contained in the Petition with reference to the domestic like product as defined in the “Scope of the Investigation,” in the appendix to this notice. To establish industry support, the petitioner provided its own 2025 production of the domestic like product.^[15] The petitioner identified itself as the only producer of PFA in the United States; therefore, the Petition is supported by 100 percent of the U.S. industry.^[16] We relied on data provided by the petitioner for purposes of measuring industry support.^[17]

Our review of the data provided in the Petition, the First General Issues Supplement, and other information readily available to Commerce indicates that the petitioner has established industry support for the Petition.^[18] First, the Petition established support from domestic producers (or workers) accounting for more than 50 percent of the total production of the domestic like product and, as such, Commerce is not required to take further action in order to evaluate industry support ( e.g., polling).^[19] Second, the domestic producers (or workers) have met the statutory criteria for industry support under section 732(c)(4)(A)(i) of the Act because the domestic producers (or workers) who support the Petition account for at least 25 percent of the total production of the domestic like product.^[20] Finally, the domestic producers (or workers) have met the statutory criteria for industry support under section 732(c)(4)(A)(ii) of the Act because the domestic producers (or workers) who support the Petition account for 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.^[21] Accordingly, Commerce determines that the Petition was filed on behalf of the domestic industry within the meaning of section 732(b)(1) of the Act.^[22]

Allegations and Evidence of Material Injury and Causation

The petitioner alleges that the U.S. industry producing the domestic like product is being materially injured, or is threatened with material injury, by reason of the imports of the subject merchandise sold at LTFV. In addition, the petitioner alleges that subject imports exceed the negligibility threshold provided for under section 771(24)(A) of the Act.^[23]

The petitioner contends that the industry's injured condition is illustrated by a significant increase in the absolute volume of subject imports; ( printed page 56119) significant increase in the volume of subject imports relative to apparent U.S. consumption; underselling and price depression and suppression; negative impact on financial performance; lost sales and revenue; decline in production, capacity utilization, and U.S. shipments; and increase in subject imports market penetration.^[24] We assessed the allegations and supporting evidence regarding material injury, threat of material injury, causation, as well as negligibility, and we have determined that these allegations are properly supported by adequate evidence, and meet the statutory requirements for initiation.^[25]

Allegations of Sales at LTFV

The following is a description of the allegations of sales at LTFV upon which Commerce based its decision to initiate an LTFV investigation of imports of PFA from India. The sources of data for the deductions and adjustments relating to U.S. price and normal value (NV) are discussed in greater detail in the India AD Initiation Checklist.

U.S. Price

Because the petitioner had reason to believe the sale or sales offer was made through a U.S. affiliate, the petitioner based constructed export price (CEP) on pricing information for PFA produced in India and sold or offered for sale in the U.S. market.^[26] The petitioner made certain adjustments to U.S. price to calculate a net ex-factory U.S. price, where applicable.^[27]

Normal Value  ^[28]

The petitioner calculated NV on home market pricing information it obtained for PFA produced in and sold, or offered for sale, in India during the POI.^[29]

Fair Value Comparisons

Based on the data provided by the petitioner, there is reason to believe that imports of PFA from India are being, or are likely to be, sold in the United States at LTFV. Based on comparisons of CEP to NV in accordance with sections 772 and 773 of the Act, the estimated dumping margins for PFA from India covered by this initiation range from 38.78 to 46.80 percent.^[30]

Initiation of LTFV Investigation

Based upon the examination of the Petition and supplemental responses, we find that they meet the requirements of section 732 of the Act. Therefore, we are initiating an LTFV investigation to determine whether imports of PFA from India are being, or are likely to be, sold in the United States at LTFV. In accordance with section 733(b)(1)(A) of the Act and 19 CFR 351.205(b)(1), unless postponed, we will make our preliminary determination no later than 140 days after the date of this initiation.

Respondent Selection

In the Petition, the petitioner identified one company in India ( i.e., Gujarat Fluorochemicals Limited (GFL)) as a producer and/or an exporter of PFA.^[31] We currently know of no additional producers/exporters of PFA from India.

Accordingly, Commerce intends to individually examine the only known producer/exporter in the investigation in the investigation from India ( i.e., GFL). We invite interested parties to comment on this issue. Such comments may include factual information within the meaning of 19 CFR 351.102(b)(21). Parties wishing to comment must do so within three business days of the publication of this notice in the Federal Register . Comments must be filed electronically using ACCESS. An electronically filed document must be received successfully in its entirety via ACCESS by 5:00 p.m. ET on the specified deadline. Because we intend to examine the only known producer/exporter in India, if no comments are received or if comments received further support the existence of only this producer/exporter in India, we do not intend to conduct respondent selection and will proceed to issuing the initial AD questionnaire to the company identified. However, if comments are received which create a need for a respondent selection process, we intend to finalize our decisions regarding respondent selection within 20 days of publication of this notice.

Distribution of a Copy of the Petition

In accordance with section 732(b)(3)(A) of the Act and 19 CFR 351.202(f), a copy of the public version of the Petition has been provided to the Government of India via ACCESS. To the extent practicable, we will attempt to provide a copy of the public version of the Petition to each exporter named in the Petition, as provided under 19 CFR 351.203(c)(2).

ITC Notification

Commerce will notify the ITC of our initiation, as required by section 732(d) of the Act.

Preliminary Determination by the ITC

The ITC will preliminarily determine, within 45 days after the date on which the Petition was filed, whether there is a reasonable indication that imports of PFA from India are materially injuring, or threatening material injury to, a U.S. industry.^[32] A negative ITC determination will result in the investigation being terminated.^[33] Otherwise, this LTFV investigation will proceed according to statutory and regulatory time limits.

Submission of Factual Information

Factual information is defined in 19 CFR 351.102(b)(21) as: (i) evidence submitted in response to questionnaires; (ii) evidence submitted in support of allegations; (iii) publicly available information to value factors under 19 CFR 351.408(c) or to measure the adequacy of remuneration under 19 CFR 351.511(a)(2); (iv) evidence placed on the record by Commerce; and (v) evidence other than factual information described in (i)-(iv). Section 351.301(b) of Commerce's regulations requires any party, when submitting factual information, to specify under which subsection of 19 CFR 351.102(b)(21) the information is being submitted ^[34] and, if the information is submitted to rebut, clarify, or correct factual information already on the record, to provide an explanation identifying the information already on the record that the factual information seeks to rebut, clarify, or correct.^[35] Time limits for the submission of factual information are addressed in 19 CFR 351.301, which provides specific time limits based on the type of factual information being submitted. Interested parties should review the regulations prior to submitting factual information in this investigation.

( printed page 56120)

Extensions of Time Limits

Parties may request an extension of time limits before the expiration of a time limit established under 19 CFR 351.301, or as otherwise specified by Commerce. In general, an extension request will be considered untimely if it is filed after the expiration of the time limit established under 19 CFR 351.301, or as otherwise specified by Commerce.^[36] For submissions that are due from multiple parties simultaneously, an extension request will be considered untimely if it is filed after 10:00 a.m. ET on the due date. Under certain circumstances, Commerce may elect to specify a different time limit by which extension requests will be considered untimely for submissions which are due from multiple parties simultaneously. In such a case, we will inform parties in a letter or memorandum of the deadline (including a specified time) by which extension requests must be filed to be considered timely. An extension request must be made in a separate, standalone submission; under limited circumstances we will grant untimely filed requests for the extension of time limits, where we determine, based on 19 CFR 351.302, that extraordinary circumstances exist. Parties should review Commerce's regulations concerning the extension of time limits and the Time Limits Final Rule prior to submitting factual information in this investigation.^[37]

Certification Requirements

Any party submitting factual information in an AD or CVD proceeding must certify to the accuracy and completeness of that information.^[38] Parties must use the certification formats provided in 19 CFR 351.303(g).^[39] Commerce intends to reject factual submissions if the submitting party does not comply with the applicable certification requirements.

Notification to Interested Parties

Interested parties must submit applications for disclosure under APO in accordance with 19 CFR 351.305. Parties wishing to participate in this investigation should ensure that they meet the requirements of 19 CFR 351.103(d) ( e.g., by filing the required letter of appearance). Note that Commerce has amended certain of its requirements pertaining to the service of documents in 19 CFR 351.303(f).^[40]

This notice is issued and published pursuant to sections 732(c)(2) and 777(i) of the Act, and 19 CFR 351.203(c).

Appendix

Scope of the Investigation

The merchandise covered by this investigation 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, -C₂ F₅, -C₃ F₇). PFA is normally associated with Chemical Abstracts Service (CAS) registry number 26655-00-5 and may also be associated with registry number 31784-04-0.

The scope includes PFA resin in primary form (including, but not limited to pellets, granules, cubes, powder, flakes, fluff, or aqueous dispersions). PFA has a minimum melting endotherm peak temperature of 265 degrees Celsius and a melt flow rate of greater than or equal to 1 g/10 min, measured in accordance with applicable ASTM standards.

PFA resin in primary form may contain minor processing aids and additives inherent to the PFA manufacturing process. This merchandise remains covered by the scope to the extent that the PFA content constitutes at least 98 percent of the material by dry weight.

PFA resin in primary form may be compounded, mixed, or otherwise blended with fillers or reinforcing materials subsequent to the manufacturing of PFA resin. These fillers or reinforcing materials include, but are not limited to, stabilizers, pigments, glass fiber, carbon fiber, carbon black, graphite, mineral fillers, or similar reinforcing additives. The scope includes only the PFA component of any PFA compounded, mixed, or otherwise blended with non-PFA fillers or reinforcing materials after production, when the PFA content constitutes at least 80 percent of the material by dry weight.

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. When packaged with another product, only the PFA resin is covered.

The scope also includes PFA that is commingled or blended with PFA from sources not subject to the investigation. In such circumstances, only the subject component of such commingled products is covered by the scope of this investigation.

Excluded from the scope of this investigation is merchandise that has a minimum melting endotherm peak temperature of less than 265°C or a melt flow rate of less than 1 g/10 min.

Also excluded from the scope of this investigation is PFA in which minor processing aids and additives used in the manufacturing of PFA resin result in PFA resin representing less than 98 percent of that merchandise by dry weight. When PFA has been compounded with fillers or reinforcing materials, the PFA component of the compounded merchandise is excluded when it is less than 80 percent of the compounded material by dry weight.

The subject merchandise is currently properly classifiable under the Harmonized Tariff Schedule of the United States (HTSUS) subheading 3904.69.5000. Products subject to this investigation may also enter under HTSUS subheadings 3904.61.0010, 3904.61.0090 and 3904.69.1000.

Although the HTSUS subheading and CAS numbers are provided for convenience and customs purposes, the written description of the scope is dispositive.
