SUPPLEMENTARY INFORMATION:

Background

On March 12, 2026, Commerce published the Preliminary Results for the 2023-2024 administrative review of the antidumping duty order on methionine from Spain ^[1] and invited interested parties to comment.^[2] The sole mandatory respondent in this review is Adisseo España S.A. (Adisseo).^[3] On July 7, 2026, Commerce extended the deadline for the final results of this review by 53 days.^[4] On August 31, 2026, Commerce extended the deadline an additional seven days.^[5] As a result, the deadline for the final results is September 8, 2026.

For a complete description of the events that occurred since the Preliminary Results, see the Issues and Decision Memorandum.^[6] The Issues and Decision Memorandum is a public document and is on file electronically via Enforcement and Compliance's Antidumping and Countervailing Duty Centralized Electronic Service System (ACCESS). ACCESS is available to registered users at access.trade.gov. In addition, a complete version of the Issues and Decision Memorandum can be accessed directly at access.trade.gov/​frnotices.

Commerce is conducting this administrative review in accordance with section 751(a) of Tariff Act of 1930, as amended (the Act).

Scope of the Order ^[7]

The merchandise covered by the Order is methionine from Spain. For a complete description of the scope of the Order, see the Issues and Decision Memorandum.

Analysis of Comments Received

All issues raised in the case and rebuttal briefs filed by parties are addressed in the Issues and Decision Memorandum and are listed in the appendix to this notice.

Changes Since the Preliminary Results

Based on our analysis of the comments received from interested parties regarding the Preliminary Results, we made certain changes to the weighted-average dumping margins calculated for Adisseo. For a discussion of these changes, see the Issues and Decision Memorandum.

Final Results of Administrative Review

For these final results, we determine that the following weighted-average dumping margins exist for the POR, September 1, 2023, through August 31, 2024:

Disclosure

Commerce intends to disclose to interested parties the calculations performed in connection with the final results of review within five days of any public announcement or, if there is no public announcement, within five days of the date of publication of this notice in the Federal Register , in accordance with 19 CFR 351.224(b).

Assessment Rates

Commerce has determined, and U.S. Customs and Border Protection (CBP) shall assess, antidumping duties on all appropriate entries of subject merchandise in accordance with these final results of review.^[8] Pursuant to 19 CFR 351.212(b)(1), we calculated importer-specific ad valorem duty assessment rates based on the ratio of the total amount of dumping calculated for the examined sales to the total entered value of the sales for which the entered value was reported. Where the respondent's weighted-average dumping margin is zero or de minimis within the meaning of 19 CFR 351.106(c)(1), or an importer-specific assessment rate is zero or de minimis, we will instruct CBP to liquidate the appropriate entries without regard to antidumping duties.

Commerce's “automatic assessment” practice will apply to entries of subject merchandise during the POR produced or exported by Adisseo for which Adisseo did not know that the merchandise it sold to the intermediary ( e.g., a reseller, trading company, or exporter) was destined for the United States. In such instances, we will instruct CBP to liquidate unreviewed entries at the all-others rate established in the LTFV investigation ( i.e., 37.53 percent ^[9] ) if there is no rate for the intermediate company(ies) involved in the transaction.^[10]

Commerce intends to issue assessment instructions to CBP no earlier than 35 days after the date of publication of the final results of this review in the Federal Register . If a timely summons is filed at the U.S. Court of International Trade, the assessment instructions will direct CBP not to liquidate relevant entries until the time for parties to file a request for a statutory injunction has expired ( i.e., within 90 days of publication).

Cash Deposit Requirements

The following deposit requirements will be effective for all shipments of the subject merchandise entered, or withdrawn from warehouse, for consumption on or after the publication date of the final results of this administrative review, as provided by section 751(a)(2)(C) of the Act: (1) the cash deposit rate for the company listed above will be equal to the weighted-average dumping margin that is established in the “Final Results of Review”; (2) for previously investigated or reviewed companies not subject to this review, the cash deposit rate will continue to be the company-specific rate published for the most recently completed segment of this proceeding in which the company participated; (3) if the exporter is not a firm covered in this review, a prior review, or the original less-than-fair-value (LTFV) investigation, but the producer is, the cash deposit rate will be the rate established for the most recently completed segment of the proceeding for the producer of the merchandise; and (4) the cash deposit rate for all other producers and exporters will continue to be 37.53 percent ad valorem, the all-others rate established in the LTFV investigation.^[11] These cash deposit requirements, when imposed, shall remain in effect until further notice.

Notification to Importers Regarding the Reimbursement of Duties

This notice also serves as a final reminder to importers of their responsibility under 19 CFR 351.402(f)(2) to file a certificate regarding the reimbursement of antidumping duties prior to liquidation of the relevant entries during the POR. Failure to comply with this requirement could result in Commerce's presumption that reimbursement of antidumping duties occurred and the subsequent assessment of double antidumping duties.

Administrative Protective Order

This notice also serves as a reminder to parties subject to an administrative protective order (APO) of their responsibility concerning the return or destruction of proprietary information disclosed under APO in accordance with 19 CFR 351.305(a)(3), which continues to govern business proprietary information in this segment of the proceeding. Timely written notification of the return or destruction of APO materials, or conversion to judicial protective order, is hereby requested. Failure to comply with the regulations and the terms of an APO is a sanctionable violation.

Notification to Interested Parties

We are issuing and publishing this notice in accordance with sections 751(a)(1) and 777(i)(1) of the Act, and 19 CFR 351.221(b)(5) and 19 CFR 351.213(h)(1).
