Information regarding the antidumping and countervailing duty petitions on Crystalline Silicon Photovoltaic Cells, Whether or Not Assembled Into Modules, From India, Indonesia, and Laos

The Petition

On July 17, 2025, the Alliance for American Solar Manufacturing and Trade ("Petitioner")¹ filed antidumping duty ("ADD") and countervailing duty ("CVD") petitions on imports of crystalline silicon photovoltaic cells, whether or not assembled into modules, ("CSPV cells and modules") from the Republic of India ("India"), the Republic of Indonesia ("Indonesia"), and the Lao People's Democratic Republic ("Laos"). The ADD petition alleges that imports of CSPV cells and modules from the targeted countries are being sold in the United States at less than fair value (that is, "dumped"). The CVD petition alleges that the Governments of the targeted countries are providing countervailable subsidies with respect to the manufacture, production, and export of CSPV cells and modules. Petitioner alleges that the domestic industry has been materially injured and is threatened with further material injury by the subject imports.

1. Petitioner has defined the products covered by the petition as follows:

Also excluded from the scope of these investigations are all products covered by the scope of the antidumping and countervailing duty orders on Crystalline Silicon Photovoltaic Cells, Whether or Not Assembled into Modules, from the People's Republic of China, 77 Fed. Reg. 73,018 (Dep't Commerce Dec. 7, 2012) (amended final deter. of sales at less than fair value, and antidumping duty order) ("Solar I"); and Crystalline Silicon Photovoltaic Cells, Whether or Not Assembled Into Modules, from the People's Republic of China, 77 Fed. Reg. 73,017 (Dep't Commerce Dec. 7, 2012) (countervailing duty order).

Also excluded from the scope of these investigations are all products covered by the scope of the antidumping and countervailing duty orders on Crystalline Silicon Photovoltaic Cells, Whether or Not Assembled Into Modules From Cambodia, Malaysia, Thailand, and the Socialist Republic of Vietnam, 90 Fed. Reg. 26,786 (Dep't Commerce June 24, 2025) (antidumping duty orders); Crystalline Silicon Photovoltaic Cells, Whether or Not Assembled Into Modules From Cambodia, Malaysia, Thailand, and the Socialist Republic of Vietnam 90 Fed. Reg. 29,843 (Dep't Commerce July 7, 2025) (antidumping duty orders; correction); and Crystalline Silicon Photovoltaic Cells, Whether or Not Assembled Into Modules, From Cambodia, Malaysia, Thailand, and the Socialist Republic of Vietnam, 90 Fed.

Merchandise covered by the investigations is currently classified in the Harmonized Tariff System of the United States ("HTSUS") under subheadings 8501.61.0000, 8507.20.80, 8541.42.0010, and 8541.43.0010. These HTSUS subheadings are provided for convenience and customs purposes; the written description of the scope of the investigations is dispositive.

Subject merchandise includes products meeting the physical description set forth in the scope language, regardless of the manufacturing technology utilized (e.g., tunnel oxide passivated contact ("TOPCon"), passivated emitter and rear cell ("PERC")). So-called "hybrid" c-Si PV cells and modules that also contain a layer of thin film are covered by the scope, consistent with the Department's scope rulings in the Solar I China case. Tandem solar cells consisting of crystalline silicon and perovskite or other cell material, including but not limited to those produced in serial fashion or by mechanical stacking, are also covered. Also consistent with the Department's Solar I scope rulings, c-Si PV cells are created once a wafer is doped and a positive/negative ("p/n junction") is created.

2. Petitioner alleges the following quantities and values of the subject imports for calendar years 2023 – 2024, which reflect imports made only under HTS subheadings 8541.42.0010 (CSPV modules) and 8541.43.0010 (CSPV cells):

Overview of ADD/CVD proceedings

There are two phases – preliminary and final – of ADD and CVD investigations. The Department of Commerce ("DOC") will determine whether imports of CSPV cells and modules from the targeted countries were dumped in the United States, and establish the ADD that will be imposed. It will also determine whether the governments of the targeted countries subsidized exports of CSPV cells and modules to the United States and establish the CVD that will be imposed. The International Trade Commission ("ITC") will determine whether imports of the subject merchandise are materially injuring, or threaten to materially injure, the domestic industry.

In order for final ADD and CVD to be imposed, both agencies must issue "affirmative" findings. We discuss below the steps involved in reaching such findings.

A. DOC Dumping Investigation

By August 6, 2025, DOC must decide whether the ADD petition contains the legally required information regarding Petitioner's standing, dumping, and injury to warrant initiating an investigation. The standard for initiation is low, requiring only that the ADD petition contains information that is "reasonably available" to Petitioner. Consequently, we expect DOC will initiate the ADD investigation by the August 6, 2025, deadline.

DOC will issue a questionnaire to, and calculate a dumping rate for, one or more producers in each of the targeted countries. These producers are referred to as "mandatory respondents." The decision of which producers will receive the questionnaire will be based on export volumes. DOC could choose only one producer from each targeted country to respond to the questionnaire if it is possible to account for 80%-85% of exports with just one producer. If not, DOC will choose two or more producers from each targeted country.

The companies that are selected as mandatory respondents will receive ADD rates based on their actual data. If a company refuses to respond to the questionnaire, it will be assigned a dumping rate based on "adverse facts available" ("AFA"), which is a punitive rate, typically based on the dumping rate calculated in the petition. The dumping rates calculated in the petition vary by country, as follows:

All other producers from each country (other than those that are issued the questionnaire) will be subject to each country's "All Others" Rate, which normally is calculated as the weighted average of the rates assigned to the mandatory respondents in each country.

The ADD questionnaire will request detailed information regarding US sales and home-market sales of CSPV cells and modules (transaction-specific prices, direct selling expenses, movement expenses, etc.) and production costs during the period of investigation ("POI"), which will be the period of July 1, 2024, through June 30, 2025. DOC will also issue one or more supplemental questionnaires to clarify information reported in the initial response. The burden of responding to the questionnaires is significantly increased if: (1) companies affiliated with the mandatory respondent also produce and/or sell the subject merchandise in the targeted countries; and/or (2) key materials used to produce the subject merchandise are purchased from affiliated suppliers.

Within 140 days after the ADD investigation is initiated (we estimate by December 24, 2025), DOC must make a preliminary determination of whether dumping exists and, if so, the estimated dumping margin for each company investigated (DOC can, and often does, postpone the preliminary determination for an additional 50 days). If DOC makes an affirmative preliminary determination, Customs and Border Protection ("CBP") will suspend liquidation of entries of CSPV cells and modules from the targeted countries and require importers to provide ADD cash deposits equal to the preliminary dumping margin calculated for the exporter multiplied by the entered value of the merchandise. Normally, the suspension of liquidation begins on the date DOC's preliminary determination is published in the Federal Register. However, if there are "critical circumstances," the suspension can apply retroactively to imports made 90 days before the preliminary determination is published.

DOC personnel normally visit the mandatory respondents' offices to verify the accuracy of the information provided in the questionnaire responses. This is normally done after the preliminary determination. If the questionnaire responses are incomplete or their accuracy cannot be verified, DOC will calculate dumping margins based on AFA, which normally means DOC will accept the dumping margins calculated by Petitioner. The verification is one of the most difficult aspects of the investigation.

Within 75 days after the preliminary determination, DOC will issue a final ADD determination (as with the preliminary determination, DOC can, and often does, postpone this deadline for an additional 60 days). DOC's final decision is based on the verified information, public hearings, and briefs submitted by counsel involved in the case. If a zero-dumping finding is made, or only "de minimis" levels (i.e., less than 2.00%) of dumping margin are found, the investigation ends. If DOC's final ADD determination is affirmative, the case proceeds to ITC for a final injury determination. DOC will also instruct CBP to continue to suspend liquidation of entries of CSPV cells and modules from the targeted countries and require ADD cash deposits at the final dumping margins determined for each exporter. Individual companies receiving zero or de minimis rates are excluded from the ADD order (if issued).

B. DOC Subsidy Investigation

As with the dumping investigation, DOC must decide whether the CVD petition contains the legally required information regarding Petitioner's standing, subsidies, and injury to warrant initiating an investigation by August 6, 2025.

DOC will then issue CVD questionnaires to the companies selected for investigation from the targeted country, as well as to the government of the targeted country. Typically, DOC chooses the two or three largest foreign exporters to respond to the questionnaire. Again, these are referred to as "mandatory respondents." The CVD questionnaire will seek information about the alleged subsidies for the POI (the most recently completed fiscal year – that is, 2024), as well as for prior years. DOC will likely issue one or more supplemental questionnaires seeking clarification or additional information.

Within 65 days after the CVD investigation is initiated (we estimate by October 10, 2025), DOC must make a preliminary determination of whether subsidization exists and, if so, the estimated CVD rate for each company investigated (DOC can, and often does, postpone the preliminary determination for an additional 65 days). If DOC makes an affirmative preliminary determination, CBP will (as in the dumping investigation) suspend liquidation of entries of CSPV cells and modules from the targeted country and require importers to provide cash deposits equal to the preliminary CVD rate calculated for the exporter multiplied by the entered value of the merchandise. Normally, the suspension of liquidation begins on the date DOC's preliminary determination is published in the Federal Register. As with ADD, if there are "critical circumstances," the suspension can apply retroactively to imports made 90 days before the preliminary determination is published.

DOC personnel will visit the mandatory respondents' offices to verify the accuracy of the information provided in the CVD questionnaire responses. DOC will also conduct on-site verifications of the information reported by the governments of the targeted countries. As in the dumping context above, DOC will first determine whether an on-site verification is feasible with respect to health and safety precautions and may conduct a "virtual verification" as an alternative to an on-site, in-person verification.

Within 75 days after the preliminary determination, DOC will issue a final CVD determination. DOC's final decision is based on the verified information, public hearings, and briefs submitted by counsel involved in the case. If a zero-subsidy finding is made, or only "de minimis" levels of subsidies (i.e., less than 1.00%) are found, the investigation ends. If DOC's final determination is affirmative, the case proceeds to ITC for a final injury determination. DOC will also instruct CBP to continue to suspend liquidation of entries of CSPV cells and modules from the targeted country, and require CVD cash deposits at the final subsidy rates determined for each exporter. Individual companies receiving zero or de minimis subsidy rates are excluded from the order.

C. ITC Injury Investigation

ITC will make a preliminary determination no later than September 2, 2025. The preliminary investigation will move very quickly. The legal standard that ITC must apply in reaching its preliminary determination is very low. Essentially, ITC must issue an affirmative preliminary injury determination unless it is clear that the US industry is not being injured or is not threatened with injury. Any doubt requires ITC to continue the investigation. Because this standard is so low, it is extremely difficult to terminate an investigation at the preliminary stage. In the final injury investigation, ITC has considerably more time to conduct its investigation and consider the facts and arguments presented by the parties. The legal standard is also higher in the final phase. Therefore, foreign producers are more likely to succeed at the final stage of ITC's investigation than at the preliminary stage. Nevertheless, it can be advantageous for foreign producers and importers to participate in the preliminary phase of the investigation so they can frame themes and issues for ITC's consideration in the final phase.

ITC will base its preliminary injury determination primarily on information received in responses to the questionnaires sent to US producers, US importers, and foreign producers. Typically, ITC circulates these questionnaires to parties within two to three business days of the filing of the petition (around July 21, 2025); and sets the deadline for them a week before the Staff Conference, discussed below (around July 31, 2025). It is important that foreign producers timely submit responses. Otherwise, ITC likely will accept Petitioner's allegations, resulting in an affirmative preliminary injury determination.

ITC Staff will conduct a conference on or around August 7, 2025. At the conference, interested parties will have an opportunity to present oral testimony and answer ITC Staff's questions. Afterwards, parties will have an opportunity to present written arguments (and supporting exhibits) in post-conference briefs, which will be due around August 12, 2025.

In the final phase, ITC conducts a more thorough investigation, with a much higher standard of injury. For the final phase, ITC crafts more detailed questionnaires for issuance to US producers, US importers, and foreign producers, as well as (unlike in the preliminary phase) for issuance to US purchasers. Before issuing the questionnaires, ITC Staff circulates draft questionnaires for the parties' comments, which is an important opportunity to ensure the questionnaires solicit information needed to support the defense. After issuing and receiving responses to the questionnaires, ITC Staff prepares a report summarizing and discussing the information and data reported in the questionnaire responses, as well as information compiled from the preliminary phase of the investigation and ITC Staff's independent research. The ITC Staff's report is important because it is a key document relied upon by the Commissioners in evaluating whether the US industry is materially injured or threatened with material injury because of the cumulated subject imports. After issuance of the ITC Staff report, parties have approximately one week to submit briefs ("prehearing briefs") presenting their arguments supporting or opposing an affirmative determination of material injury (or threat thereof). Normally one week after the deadline for prehearing briefs, ITC holds a public hearing at which the Commissioners (i.e., the decision makers) preside. During the hearing, both sides – Petitioner in support of ADD/CVD and the foreign producers and US importers/purchasers opposed to ADD/CVD – will each have one hour to make an affirmative presentation, followed by a question-and-answer session with the Commissioners. For the defense, in particular, it is critical that industry witnesses (such as importers and US purchasers) opposed to the imposition of ADD/CVD participate and testify at the ITC hearing. After the hearing, the parties have approximately one week to prepare "posthearing" briefs, which typically focus on rebutting the other side's arguments and answering specific questions raised by the Commissioners at the hearing. Several days before the date of the ITC's scheduled vote, parties have one last opportunity to submit final comments in the case. Unlike the preliminary phase, which takes place over the course of approximately six weeks, the final phase normally takes place over the course of approximately four months.
