SUPPLEMENTARY INFORMATION:

Background

On March 16, 2026, Commerce published the Preliminary Results of the 2023-2024 administrative review of the antidumping duty order of OCTG from Vietnam in the Federal Register and invited interested parties to comment.^[1] On April 6, 2026, we received case briefs from SeAH VINA, and from Axis Pipe and Tube, Borusan Pipe US Inc., Vallourec Star, and Welded Tube USA, Inc. (collectively, the domestic interested parties).^[2] On April 13, 2026, SeAH VINA and the domestic interested parties submitted rebuttal briefs.^[3] Between July 10 and September 4, 2026, Commerce extended the deadline for the final results of this review by 59 days.^[4] Accordingly, the deadline for these final results is September 11, 2026. Commerce conducted this administrative review in accordance with section 751(a)(1)(B) of the Tariff Act of 1930, as amended (the Act).

For a complete description of the events that occurred since the Preliminary Results, see the Issues and Decision Memorandum.^[5] 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), 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 ^[6]

The merchandise covered by the Order is OCTG from Vietnam. For a complete description of the scope of the Order, see the Issues and Decision Memorandum.^[7]

Analysis of Comments Received

All issues raised in case and rebuttal briefs filed by interested parties in this administrative review are addressed in the Issues and Decision Memorandum. A list of the issues addressed in the Issues and Decision Memorandum is provided in Appendix I 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 weighted-average dumping margin calculation for SeAH VINA. For further discussion of these changes, 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 September 1, 2023, through August 31, 2024:

Disclosure

Commerce intends to disclose the calculations performed in connection with these final results of review to interested parties in this review within five days after public announcement of the final results 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

Pursuant to section 751(a)(2)(C) of the Act and 19 CFR 351.212(b)(1), Commerce has determined, and U.S. Customs and Border Protection (CBP) shall assess, antidumping duties on all appropriate entries of subject merchandise covered by the final results of this review.

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 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]

In accordance with Commerce's “automatic assessment” practice, for entries of subject merchandise during the POR produced by SeAH VINA 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 Vietnam-wide rate ( i.e., 111.47 percent) ^[9] if there is no rate for the intermediate companies involved in the transaction.^[10]

The final results of this review shall be the basis for the assessment of ( printed page 58850) antidumping duties on entries of merchandise covered by the final results of this review and for future deposits of estimated duties, where applicable.^[11]

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 cash deposit requirements will be effective upon publication of the final results of this administrative review for all shipments of the subject merchandise from Vietnam entered, or withdrawn from warehouse, for consumption on or after the publication date, as provided for by section 751(a)(2)(C) of the Act: (1) for SeAH VINA, the cash deposit rate will be the margin listed above; (2) for previously investigated or reviewed Vietnamese and non-Vietnamese exporters not listed above that received a separate rate in a prior segment of this proceeding, the cash deposit rate will continue to be the exporter-specific rate published for the most-recently completed segment of this proceeding in which the exporter was reviewed; (3) for all Vietnamese exporters of subject merchandise which have not been found to be entitled to a separate rate, the cash deposit rate will be the rate established for the Vietnam-wide entity, which is 111.47 percent; ^[12] and (4) for all non-Vietnamese exporters of subject merchandise which have not received their own rate, the cash deposit rate will be the rate applicable to the Vietnamese exporter that supplied that non-Vietnamese exporter with the subject merchandise. These cash deposit requirements, when imposed, shall remain in effect until further notice.

Notification to Importers

This notice 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 this POR. Failure to comply with this requirement could result in Commerce's presumption that reimbursement of antidumping duties has occurred and the subsequent assessment of double antidumping duties

Administrative Protective Order (APO)

This notice also serves as a final reminder to parties subject to an 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

These final results of review are issued and published in accordance with sections 751(a)(1) and 777(i)(1) of the Act, and 19 CFR 351.221(b)(5).
