SUPPLEMENTARY INFORMATION:

Background

On May 13, 2026, Commerce published the Preliminary Results and invited comments from interested parties.^[1] On August 25, 2026, in accordance with section 751(a)(3)(A) of the Tariff Act of 1930, as amended (the Act), Commerce extended the final results of this review to November 2, 2026.^[2] Commerce conducted this administrative review in accordance with section 751 of the Act.

A summary of the events that occurred since Commerce published these Preliminary Results, as well as a full discussion of the issues raised by parties for these final results, may be found in the Issues and Decision Memorandum.^[3] 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, which 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.

Scope of the Order^[4]

The merchandise covered by the Order is OCTG from Mexico. For a complete description of the scope of the Order, see the Issues and Decision Memorandum.^[5]

Analysis of Comments Received

All issues raised by parties in their case briefs are addressed in the Issues and Decision Memorandum.^[6] For a list of the issues raised by parties, see the appendix to this notice.

Changes Since the Preliminary Results

Based on our review of the record and our analysis of the comments received, Commerce made certain changes to the preliminary margin calculations for Tubos de Acero de Mexico, S.A. (TAMSA) for these final results of review. For a discussion of the issues, see the Issues and Decision Memorandum.

Final Results of Administrative Review

Commerce determines that the following estimated weighted-average dumping margin exists for the period November 1, 2023, through October 31, 2024:

Disclosure

Commerce intends to disclose its calculations and analysis performed for these final results within five days of any public announcement or, if there is no public announcement, within five days after the date of publication of this notice, in accordance with 19 CFR 351.224(b).

Assessment Rates

Pursuant to section 751(a)(2)(C) of the Act and 19 CFR 351.212(b)(1), Commerce shall determine, and U.S. Customs and Border Protection (CBP) shall assess, antidumping duties on all appropriate entries of subject merchandise in accordance with the final results of this review.^[7]

Because the mandatory respondent's weighted-average dumping margin is not zero or de minimis ( i.e., less than 0.50 percent) in the final results of this review, Commerce calculated importer-specific assessment rates on the basis of the ratio of the total amount of dumping calculated for each importer's examined sales to the total entered value of those sales. Where we do not have entered values for all U.S. sales to a particular importer, we calculated an importer-specific, per-unit assessment rate on the basis of the ratio of the total amount of dumping calculated for the importer's examined sales to the total quantity of those sales. To determine whether an importer-specific, per-unit assessment rate is de minimis, in accordance with 19 CFR 351.106(c)(2), we also calculated an importer-specific ad valorem ratio based on estimated entered values. Where a mandatory respondent's weighted-average dumping margin is ( printed page 69809) zero or de minimis or where an importer-specific ad valorem assessment rate is zero or de minimis, we will instruct CBP to liquidate appropriate entries without regard to antidumping duties.^[8]

These final results of this review shall be the basis for the assessment of antidumping duties on entries of merchandise covered by the final results of this review and for future deposits of estimated duties, where applicable.^[9]

Commerce intends to issue assessment instructions to CBP no earlier than 41 days ^[10] 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 cash deposit requirements will be effective upon publication of this notice for all shipments of subject merchandise entered, or withdrawn from warehouse, for consumption on or after the publication of these final results, as provided by section 751(a)(2) of the Act: (1) the cash deposit rate for company subject to this review will be equal to the company-specific weighted-average dumping margin established in the final results of this administrative review; (2) for merchandise exported by producers or exporters not covered in this administrative review but covered in a prior segment of the proceeding, the cash deposit rate will continue to be the company specific rate published for the most recently completed segment of this proceeding; (3) if the exporter is not a firm covered in this review, a prior review, or the original investigation, but the producer is, the cash deposit rate will be the rate established for the most recently completed segment of this proceeding for the producer of the subject merchandise; and (4) the cash deposit rate for all other producers or exporters will continue to be 44.93 percent, the all-others rate established in the less-than-fair-value 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 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 this review period. 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 (APO)

This notice also serves as a reminder to parties subject to APO of their responsibility concerning the disposition 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 351.213(h) and 19 CFR 351.221(b)(5).
