SUPPLEMENTARY INFORMATION:

Background

On December 18, 2024, based on timely requests for review, in accordance with 19 CFR 351.221(c)(1)(i), we initiated an administrative review of the antidumping duty (AD) order on certain oil country tubular goods (OCTG) from Mexico.^[1] On February 5, 2025, Commerce selected Tubos de Acero de Mexico, S.A. (TAMSA) as the mandatory respondent in this review.^[2] Due to the lapse in appropriations and Federal Government shutdown, on November 14, 2025, Commerce tolled all deadlines in administrative proceedings by 47 days.^[3] Additionally, due to a backlog of documents that were electronically filed via Enforcement and Compliance's Antidumping and Countervailing Duty Centralized Electronic Service System (ACCESS) ( printed page 27015) during the Federal Government shutdown, on November 24, 2025, Commerce tolled all deadlines in administrative proceedings by an additional 21 days.^[4] Between December 30, 2025, and February 27, 2026, we extended the preliminary results of this review to no later than May 7, 2026.^[5]

For a complete description of the events that followed the initiation of this review, see the Preliminary Decision Memorandum.^[6] A list of the topics discussed in the Preliminary Decision Memorandum is attached as an appendix to this notice. The Preliminary Decision Memorandum is a public document and is on file electronically via ACCESS. ACCESS is available to registered users at https://access.trade.gov. In addition, a complete version of the Preliminary Decision Memorandum can be accessed directly at https://access.trade.gov/​frnotices.

Scope of the Order

The product covered by the Order is OCTG from Mexico. For a complete description of the scope of the Order, see the Preliminary Decision Memorandum.^[7]

Recission of Administrative Review, In Part

Pursuant to 19 CFR 351.213(d)(3), it is Commerce's practice to rescind an administrative review of an AD order where it concludes that there were no suspended entries of subject merchandise during the POR.^[8] Normally, upon completion of an administrative review, the suspended entries are liquidated at the AD assessment rate for the review period.^[9] Therefore, for an administrative review to be conducted, there must be a reviewable, suspended entry that Commerce can instruct U.S. Customs and Border Protection (CBP) to liquidate at the AD assessment rate calculated for the POR.^[10] Commerce notified all interested parties of its intent to rescind the instant review regarding Siderca S.A.I.C. and Vallourec Oil & Gas Mexico, S.A. de C.V. because there were no reviewable, suspended entries of subject merchandise from these companies during the POR and invited interested parties to comment.^[11] No party commented on this memorandum. In the absence of any suspended entries of subject merchandise from these companies during the POR, we are rescinding this administrative review for Siderca S.A.I.C. and Vallourec Oil & Gas Mexico, S.A. de C.V., in accordance with 19 CFR 351.213(d)(3).

Methodology

Commerce is conducting this review in accordance with section 751(a) of the Tariff Act of 1930, as amended (the Act). Constructed export price is calculated in accordance with section 772 of the Act. NV is calculated in accordance with section 773 of the Act. For a full description of the methodology underlying our conclusions, see the Preliminary Decision Memorandum.

Preliminary Results of Review

As a result of this review, we preliminarily determine the following estimated weighted-average dumping margin exists for the period November 1, 2023, through October 31, 2024:

Disclosure

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

Public Comment

Case briefs or other written comments may be submitted to the Assistant Secretary for Enforcement and Compliance. Pursuant to 19 CFR 351.309(c)(1)(ii), we have modified the deadline for interested parties to submit case briefs to Commerce to no later than 21 days after the date of publication of this notice.^[12] Rebuttal briefs, limited to issues raised in the case briefs, may be filed no later than five days after the date for filing case briefs.^[13] Interested parties who submit case briefs or rebuttal briefs in this proceeding must submit: (1) a table of contents listing each issue; and (2) a table of authorities.^[14] All briefs must be filed electronically using ACCESS. An electronically filed document must be received successfully in its entirety in ACCESS by 5:00 p.m. Eastern Time on the established deadline.

As provided under 19 CFR 351.309(c)(2)(iii) and (d)(2)(iii), we request that interested parties provide at the beginning of their briefs a public, executive summary for each issue raised in their briefs.^[15] Further, we request that interested parties limit their public executive summary of each issue to no more than 450 words, not including citations. We intend to use the public executive summaries as the basis of the comment summaries included in the issues and decision memorandum that will accompany the final results of this administrative review. We request that interested parties include footnotes for relevant citations in the public executive summary of each issue. Note that Commerce has amended certain of its requirements pertaining to the service of documents in 19 CFR 351.303(f).^[16]

Pursuant to 19 CFR 351.310(c), interested parties who wish to request a hearing must submit a written request to the Assistant Secretary for Enforcement and Compliance, filed electronically via ACCESS by 5:00 p.m. Eastern Time within 30 days after the date of publication of this notice. Requests should contain: (1) the party's name, address, and telephone number; (2) the number of participants, and whether any participant is a foreign national; and (3) a list of issues to be discussed. Issues raised in the hearing will be limited to those raised in the respective case briefs. If a request for a hearing is made, parties will be notified of the time and ( printed page 27016) date for the hearing.^[17] Parties should confirm by telephone the date, time, and location of the hearing two days before the scheduled date.

Assessment Rates

Upon issuance of the final results, Commerce shall determine, and CBP shall assess, antidumping duties on all appropriate entries covered by this review. The final results of this review shall be the basis for the assessment of antidumping duties on entries of merchandise covered by this review and for future deposits of estimated duties, where applicable.^[18]

If TAMSA's weighted-average dumping margin for a mandatory respondent is not zero or de minimis ( i.e., less than 0.50 percent) in the final results of this review, Commerce intends to calculate an importer-specific assessment rate on the basis of the ratio of the total amount of dumping calculated for each importer's examined sales and the total entered value of those sales. Where we do not have entered values for all U.S. sales to a particular importer, we will calculate 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.^[19] To determine whether an importer-specific, per-unit assessment rate is de minimis, in accordance with 19 CFR 351.106(c)(2), we also will calculate an importer-specific ad valorem ratio based on estimated entered values. If TAMSA's weighted-average dumping margin is zero or de minimis or where an importer-specific assessment rate is zero or de minimis, we will instruct CBP to liquidate appropriate entries without regard to antidumping duties.^[20]

In accordance with Commerce's “automatic assessment” practice, for entries of subject merchandise during the POR produced by TAMSA for which it did not know that the merchandise was destined for the United States, we intend to instruct CBP to liquidate those entries at the all-others rate calculated in the less-than-fair-value (LTFV) investigation if there is no rate for the intermediate company(ies) involved in the transaction.^[21]

For Siderca S.A.I.C. and Vallourec Oil & Gas Mexico, S.A. de C.V., for which this administrative review is rescinded, Commerce will instruct CBP to assess antidumping duties on all appropriate entries. Antidumping duties shall be assessed at rates equal to the cash deposit rate for estimated antidumping duties required at the time of entry, or withdrawal from warehouse, for consumption, in accordance with 19 CFR 351.212(c)(1)(i). Commerce intends to issue these rescission instructions to CBP no earlier than 41 days after the date of publication of this notice in the Federal Register .

Commerce intends to issue assessment instructions to CBP regarding TAMSA, Siderca S.A.I.C., and Vallourec Oil & Gas Mexico, S.A. de C.V. no earlier than 41 days after the date of publication of the final results of this review in the Federal Register , in accordance with 19 CFR 356.8(a). 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 that established in the final results of this administrative review, except if the rate is less than 0.50 percent and, therefore, de minimis within the meaning of 19 CFR 351.106(c)(1), in which case the cash deposit rate will be zero; (2) for previously investigated or reviewed companies not covered by this review, the cash deposit rate will continue to be the company-specific cash deposit 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 LTFV investigation, but the manufacturer is, then the cash deposit rate will be the rate established in the most recent segment for the manufacturer of the merchandise; and (4) the cash deposit rate for all other manufacturers or exporters will continue to be 44.93 percent, the all-others rate established in the LTFV investigation.^[22] These cash deposit requirements, when imposed, shall remain in effect until further notice.

Final Results of Review

Unless otherwise extended, Commerce intends to issue the final results of this administrative review, including the results of our analysis of issues raised by the parties in any written briefs, within 120 days of publication of these preliminary results in the Federal Register , pursuant to section 751(a)(3)(A) of the Act and 19 CFR 351.213(h)(1).

Notification to Importers

This notice also serves as a preliminary reminder to importers of their responsibility under 19 CFR 351.402(f)(2) to file a certificate regarding the reimbursement of antidumping and/or countervailing 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 and/or countervailing duties occurred and the subsequent assessment of double antidumping duties, and/or an increase in the amount of antidumping duties by the amount of the countervailing duties.

Notification to Interested Parties

We are issuing and publishing these preliminary results of review in accordance with sections 751(a)(1) and 777(i) of the Act, and 19 CFR 351.221(b)(4).
