**SUPPLEMENTARY INFORMATION:**
**Background**
On September 11, 2025, Commerce published the *Preliminary Results* and invited comments from interested parties. [^1] No interested party submitted comments on the *Preliminary Results.* Accordingly, the final results remain unchanged from the *Preliminary Results,* and thus, there is no decision memorandum accompanying this notice.
[^1]*See Large Diameter Welded Pipe from the Republic of Türkiye: Preliminary Results and Rescission, in Part, of Countervailing Duty Administrative Review; 2023,* 90 FR 44019 (September 11, 2025) ( *Preliminary Results* ), and accompanying Preliminary Decision Memorandum (PDM).
Due to the lapse in appropriations and Federal Government shutdown, on November 14, 2025, Commerce tolled all deadlines in administrative proceedings by 47 days. [^2] 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) during the Federal Government shutdown, on November 24, 2025, Commerce tolled all deadlines in administrative proceedings by an additional 21 days. [^3] Accordingly, the deadline for these final results is now March 18, 2026.
[^2]*See* Memorandum, “Deadlines Affected by the Shutdown of the Federal Government,” dated November 14, 2025.
[^3]*See* Memorandum, “Tolling of all Case Deadlines,” dated November 24, 2025.
Commerce conducted this administrative review in accordance with section 751 of the Tariff Act of 1930, as amended (the Act).
**Scope of the Order**
The merchandise covered by the *Order* is welded pipe from Türkiye. For a complete description of the scope of the *Order, see* the *Preliminary Results* PDM.
**Final Results of Review**
For these final results, we determine that the following net countervailable subsidy rate exists for the period January 1, 2023, through December 31, 2023:
| Producer/exporter | Subsidy rate |
| --- | --- |
| HDM Celik Boru Sanyai Ve Ticaret A.S. | 4.40 |
**Disclosure**
[^4] This rate also applies to HDM Spiral Kaynakli Celik Boru A.S., the English name of which is HDM Spirally Welded Steel Pipe Inc.
Normally, Commerce will disclose to the parties in a proceeding the calculations performed in connection with the final results of a review within five days of any public announcement or, if there is no public announcement, within five days of the date of publication of the notice of final results in the *Federal Register* , in accordance with 19 CFR 351.224(b). However, as we have made no changes from the *Preliminary Results,* there are no new calculations to disclose.
**Assessment Rates**
Pursuant to section 751(a)(2)(C) of the Act and 19 CFR 351.212(b)(2), Commerce has determined, and U.S. Customs and Border Protection (CBP) shall assess, countervailing duties on all appropriate entries of subject merchandise in accordance with the final results of this review. 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 Rates**
In accordance with section 751(a)(1) of the Act, Commerce intends to instruct CBP to collect cash deposits of estimated countervailing duties in the amounts shown above for HDM Celik Boru Sanyai Ve Ticaret A.S. for shipments of the subject merchandise entered, or withdrawn from warehouse for consumption on or after the date of publication of the final results of this administrative review. For all non-reviewed firms, we will instruct CBP to continue to collect cash deposits of estimated countervailing duties at the most recent company-specific or all-others rate applicable to the company, as appropriate. These cash deposits, effective upon the publication of the final results of this review, shall remain in effect until further notice.
**Administrative Protective Order**
This notice serves as the only reminder to parties subject to an administrative protective order (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 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) of the Act and 19 CFR 351.221(b)(5).
