SUPPLEMENTARY INFORMATION:

Background

In accordance with sections 735(d) and 777(i) of the Tariff Act of 1930, as amended (the Act), on September 16, 2026, Commerce published its affirmative final determinations in the less-than-fair-value (LTFV) investigations of solar cells from India, Indonesia, and Laos.^[1] On September 16, 2026, the Alliance for American Solar Manufacturing and Trade (the petitioner) timely alleged that Commerce made ministerial errors in the Laos Final Determination.^[2] Section 351.224(f) of Commerce's regulations define ministerial errors as errors in addition, subtraction, or other arithmetic function, clerical errors resulting from inaccurate copying, duplication, or the like, and any other type of unintentional error which Commerce considers ministerial. We reviewed the allegations and determined that we made a ministerial error in the Laos Final Determination. See “Amendment to the Laos Final Determination” section below for further discussion.

On November 2, 2026, pursuant to section 735(d) of the Act, the ITC notified Commerce of its final affirmative determinations that an industry in the United States is materially injured by reason of LTFV imports of solar cells from India, Indonesia, and Laos within the meaning of section 735(b)(1)(A)(i) of the Act.^[3]

Scope of the Orders

The merchandise covered by these orders is solar cells from India, Indonesia, and Laos. For a complete description of the scope of the orders, see the appendix to this notice.

Amendment to the Laos Final Determination

On September 16, 2026, the petitioner timely submitted ministerial error allegations in the Laos Final Determination.^[4] Commerce reviewed the record and, on October 13, 2026, agreed that one of the petitioner's alleged errors constituted a ministerial error within the meaning of section 735(e) of the Act and 19 CFR 351.224(f).^[5] Specifically, Commerce determined that it had erred in removing section 201 duties from reported U.S. duties for all of Solarspace Technology (Laos) Sole Co., Ltd.'s (Solarspace) U.S. sales, instead of limiting the deduction to those U.S. sales which incurred these duties, as the petitioner alleged; however, Commerce also determined that, because the petitioner's allegation regarding the exclusion of Solarspace's U.S. sales through Trina Solar Science & Technology (Thailand) Company Limited and Trina Solar Energy Development Pte. Ltd. in the margin calculation pertained to a methodological decision, it was not a ministerial error.^[6] Pursuant to 19 CFR 351.224(e), Commerce is amending the Laos Final Determination to reflect the correction of the ministerial error, as described in the Ministerial Error Memorandum.^[7] Correcting this error changes Solarspace's final dumping margin. In addition, in the Laos Final Determination, because we based the rate for the non-examined separate rate respondents and the Laos-wide entity on the dumping margin calculated for Solarspace,^[8] we have also revised the rate assigned to these entities. The amended weighted-average dumping margins for Laos are listed in the “Estimated Weighted-Average Dumping Margins” section, below.

Antidumping Duty Orders

As stated above, based on the ITC's affirmative final determinations that an ( printed page 70863) industry in the United States is materially injured within the meaning of section 735(b)(1)(A)(i) of the Act by reason of LTFV imports of solar cells from India, Indonesia, and Laos,^[9] in accordance with section 735(c)(2) of the Act, Commerce is issuing these AD orders. Because the ITC determined that imports of solar cells from India, Indonesia, and Laos are materially injuring a U.S. industry, unliquidated entries of subject merchandise from India, Indonesia, and Laos entered, or withdrawn from warehouse, for consumption, are subject to the assessment of antidumping duties.

Therefore, in accordance with section 736(a)(1) of the Act, Commerce intends to direct U.S. Customs and Border Protection (CBP) to assess, upon further instructions by Commerce, antidumping duties equal to the amount by which the normal value of the merchandise exceeds the export price (or constructed export price) of the merchandise, on all relevant entries of solar cells from India, Indonesia, and Laos, which are entered, or withdrawn from warehouse, for consumption, on or after April 28, 2026, the date of publication of the Preliminary Determinations,^[10] but will not include entries after the expiration of the provisional measures period and before publication of the ITC's final injury determinations under section 735(d) of the Act, as further described in the “Provisional Measures” section of this notice.

Continuation of Suspension of Liquidation and Cash Deposits

Except as noted in the “Provisional Measures” section of this notice, in accordance with section 735(c)(1)(B) of the Act, Commerce intends to instruct CBP to continue to suspend liquidation on all relevant entries of solar cells from India, Indonesia, and Laos. These instructions suspending liquidation will remain in effect until further notice.

Commerce will also instruct CBP to require cash deposits equal to the estimated weighted-average dumping margins indicated in the tables below. Effective on the date of publication in the Federal Register of the notice of the ITC's final affirmative injury determinations, CBP will require, at the same time as importers would normally deposit estimated customs duties on subject merchandise, a cash deposit equal to the rates listed in the table below.

Estimated Weighted-Average Dumping Margins

The estimated weighted-average dumping margins are as follows:

Provisional Measures

Section 733(d) of the Act states that suspension of liquidation pursuant to an affirmative preliminary determination may not remain in effect for more than four months, except where exporters representing a significant proportion of exports of the subject merchandise request that Commerce extend the four-month period to no more than six months. At the request of exporters that account for a significant proportion of exports of solar cells from India, Indonesia, and Laos, Commerce extended the four-month period to six months in each of these investigations.^[11]

The extended provisional measures period, beginning on the date of publication of the Preliminary Determinations on April 28, 2026,^[12] ended on October 24, 2026. Therefore, in accordance with section 736(a)(1) of the Act and our practice,^[13] Commerce will instruct CBP to terminate the suspension of liquidation and to liquidate, without regard to antidumping duties, unliquidated entries of solar cells from India, Indonesia, and Laos entered, or withdrawn from warehouse, for consumption on or after October 25, 2026, the date on which the provisional measures expired, until and through the day preceding the date of publication of the ITC's final affirmative injury determinations in the Federal Register . Suspension of liquidation and the collection of cash deposits will resume on the date of publication of the ITC's final determinations in the Federal Register .

Establishment of the Annual Inquiry Service Lists

On September 20, 2021, Commerce published the Final Rule in the Federal Register .^[14] On September 27, 2021, Commerce also published the Procedural Guidance in the Federal Register .^[15] The Final Rule and Procedural Guidance provide that Commerce will maintain an annual inquiry service list for each order or suspended investigation, and any interested party submitting a scope ruling application or request for circumvention inquiry shall serve a copy of the application or request on the persons on the annual inquiry service list for that order, as well as any companion order covering the same merchandise from the same country of origin.

In accordance with the Procedural Guidance, for orders published in the Federal Register after November 4, 2021, Commerce will create an annual inquiry service list segment in Commerce's online e-filing and document management system, Antidumping and Countervailing Duty Electronic Service System (ACCESS), available at access.trade.gov, within five business days of publication of the notice of the order. Each annual inquiry service list will be saved in ACCESS, under each case number, and under a specific segment type called “AISL-Annual Inquiry Service List.” ^[16]

Interested parties who wish to be added to the annual inquiry service list for an order must submit an entry of appearance to the annual inquiry service list segment for the order in ACCESS within 30 days after the date of publication of the order. For ease of administration, Commerce requests that law firms with more than one attorney representing interested parties in an order designate a lead attorney to be included on the annual inquiry service list. Commerce will finalize the annual inquiry service list within five business days thereafter. As mentioned in the Procedural Guidance,^[17] the new annual inquiry service list will be in place until the following year, when the Opportunity Notice for the anniversary month of the order is published.

Commerce may update an annual inquiry service list at any time as needed based on interested parties' amendments to their entries of appearance to remove or otherwise modify their list of members and representatives, or to update contact information. Changes or announcements pertaining to these procedures will be posted to the ACCESS website at access.trade.gov.

Special Instructions for the Petitioner and Foreign Governments

In the Final Rule, Commerce stated that, “after an initial request and placement on the annual inquiry service list, both petitioners and foreign governments will automatically be placed on the annual inquiry service list in the years that follow.” ^[18] Accordingly, as stated above, the petitioner and foreign governments should submit their initial entry of appearance after publication of this notice in order to appear in the first annual inquiry service lists for these orders. Pursuant to 19 CFR 351.225(n)(3), the petitioner and foreign governments will not need to resubmit their entries of appearance each year to continue to be included on the annual inquiry service list. However, the petitioners and foreign governments are responsible for making amendments to their entries of appearance during the annual update to the annual inquiry service list in accordance with the procedures described above.

Notification to Interested Parties

This notice constitutes the AD orders with respect to solar cells from India, Indonesia, and Laos pursuant to section 736(a) of the Act. Interested parties can ( printed page 70865) find a list of AD and countervailing duty orders currently in effect at www.trade.gov/​data-visualization/​adcvd-proceedings.

The amended Laos final determination and these AD orders are published in accordance with sections 735(e) and 736(a) of the Act, and 19 CFR 351.224(e) and 19 CFR 351.211(b).
