SUPPLEMENTARY INFORMATION:

Background

On March 16, 2026, Commerce published in the Federal Register the Preliminary Results.^[1] On June 11, 2026, Commerce issued a post-preliminary analysis addressing the particular market situation alleged by the domestic interested parties.^[2] Between June 26, and September 2, 2026, we extended the deadline for the final results of this proceeding by 60 days.^[3] Accordingly, the deadline for these final results is now September 14, 2026.^[4] Commerce conducted this review in accordance with section 751(a) of the Tariff Act of 1930, as amended (the Act).

A summary of the events that occurred since Commerce published the 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.^[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, which is available to registered users at access.trade.gov. In addition, a complete version of the Issues and Decision Memorandum can be accessed at access.trade.gov/​frnotices.

Scope of the Order ^[6]

The product covered by the Order is OCTG from Korea. 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 by interested parties in this administrative review are addressed in the Issues and Decision Memorandum. For a list of issues raised by parties, see Appendix I.

Changes Since the Preliminary Results

We have made three changes since the Preliminary Results, which are: (1) to rely on U.S. benchmark prices to calculate the particular market situation (PMS) adjustment, (2) to apply a different source to calculate constructed value (CV) profit and selling expense ratios for NEXTEEL and SeAH, and (3) to apply a correction to SeAH's margin program by updating the constructed export price (CEP) profit rate.

Rate for Non-Individually Examined Respondents

The statute and Commerce's regulations at the time of initiation do not address the establishment of a rate to be applied to companies not selected for individual examination when Commerce limits its examination in an administrative review pursuant to section 777A(c)(2) of the Act. For the rate for non-selected respondents in an administrative review, generally, Commerce looks to section 735(c)(5) of the Act, which provides instructions for calculating the all-others rate in a market economy investigation, for guidance when calculating the rate for companies which were not selected for individual examination in an administrative review. Under section 735(c)(5)(A) of the Act, the all-others rate is normally “an amount equal to the weighted average of the estimated weighted-average dumping margins established for exporters and producers individually investigated, excluding any zero or de minimis margins, and any margins determined entirely {on the basis of facts available}.” For these final results, we are assigning the non-individually examined respondents a rate of 19.87 percent, which is the simple average of the weighted-average dumping margins calculated for NEXTEEL and SeAH.^[7]

Final Results of Review

For these final results, Commerce determines that the following weighted-average dumping margins exist for the ( printed page 60584) period September 1, 2023, through August 31, 2024:

Disclosure

Commerce intends to disclose the calculations performed for these final results of review within five days after the date of publication of this notice in the Federal Register , in accordance with 19 CFR 351.224(b).

Assessment

Pursuant to section 751(a)(2)(C) of the Act and 19 CFR 351.212(b), Commerce shall determine, and CBP shall assess, antidumping duties on all appropriate entries of subject merchandise in accordance with the final results of this review.^[9]

For entries of subject merchandise during the POR produced by NEXTEEL or SeAH for which it did not know its merchandise was destined for the United States, we will instruct CBP to liquidate unreviewed entries at the all-others rate in the less-than-fair-value (LTFV) investigation if there is no rate for the intermediate company(ies) involved in the transaction.^[10] For the companies that were not selected for individual examination, we will instruct CBP to liquidate entries at the rates established in these final results of review. Commerce intends to issue appropriate 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 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 for by section 751(a)(2)(C) of the Act: (1) the cash deposit rates for the companies listed in these final results will be equal to the simple-average dumping margins established in the final results of this review; (2) for merchandise exported by producers or exporters not covered in this review but covered in a prior segment of this proceeding, the cash deposit rate will continue to be the company-specific rate published for the most recently completed segment in which the company was reviewed; (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 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 5.24 percent,^[11] the all-others rate established in the LTFV investigation. These cash deposit requirements, when imposed, shall remain in effect until further notice.

Notification to Importers

This notice also serves as a final reminder to importers of their responsibility under 19 CFR 351.402(f) 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 did occur and the subsequent assessment of doubled antidumping duties.

Administrative Protective Order

This notice also serves as a reminder to parties subject to 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 terms of an APO is a sanctionable violation.

Notification to Interested Parties

We are issuing and publishing these final results in accordance with sections 751(a)(1) and 777(i) of the Act, and 19 CFR 351.221(b)(5).
