**SUPPLEMENTARY INFORMATION:**
**Background**
On July 11, 2025, Commerce published in the *Federal Register* the *Preliminary Results* of the 2023-2024 administrative review [^1] of the antidumping duty order on R-125 from China and invited interested parties to comment. [^2]

[^2]*Id.* 90 FR at 30868.
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) during the Federal Government shutdown, on November 24, 2025, Commerce tolled all deadlines in administrative proceedings by an additional 21 days. [^4] The deadline for the final results is now January 16, 2026.
[^3]*See* Memorandum, “Deadlines Affected by the Shutdown of the Federal Government,” dated November 14, 2025.
[^4]*See* Memorandum, “Tolling of all Case Deadlines,” dated November 24, 2025.

The products subject to the *Order* is R-125 from China. [^6] A full description of the scope of the *Order* is provided in the Issues and Decision Memorandum.

**Analysis of Comments Received**
All issues raised in briefs filed by parties in this administrative review are addressed in the Issues and Decision Memorandum and are listed in the appendix to this notice.
**Separate Rate**
No parties commented on Commerce's preliminary decision to grant a separate rate to the Sanmei Companies, [^7] nor on Commerce's preliminary decision not to grant a separate rate for Yonghe. [^8] We have made no changes to Commerce's preliminary separate rate determination for these final results.
[^7] The Sanmei Companies are comprised of Zhejiang Sanmei; Jiangsu Sanmei Chemical Ind. Co., Ltd.; and Fujian Qingliu Dongying Chemical Ind. Co., Ltd. *See Pentafluoroethane (R-125) from the People's Republic of China: Final Results of Antidumping Duty Administrative Review; 2021-2023,* 89 FR 66033 (August 14, 2024).
[^8]*See Preliminary Results* at “Separate Rates” section.
**China-Wide Entity**
As noted above, we continue to find that Yonghe is ineligible for a separate rate. Therefore, for the final results, we continue to find that Yonghe is part of the China-wide entity.
Under Commerce's policy regarding the conditional review of the China-wide entity, [^9] the China-wide entity will not be under review unless a party specifically requests, or Commerce self-initiates, a review of the entity. Because no party requested a review of the China-wide entity in this review, the entity is not under review, and the entity's rate ( *i.e.,* 267.51 percent) is not subject to change. [^10]

[^10]*See Order,* 87 FR at 12082.
**Changes Since the Preliminary Results**
Based on our review of the record and comments received from interested parties regarding our *Preliminary Results,* and for the reasons explained in the Issues and Decision Memorandum, we made certain changes to the margin calculation for Sanmei. [^11]
[^11]*See* Issues and Decision Memorandum at part IV.
**Final Results of Review**
Commerce determines that the following estimated weighted-average dumping margin exists for the period March 1, 2023, through February 29, 2024:
| Exporter | Weighted- |
| --- | --- |
| Zhejiang Sanmei Chemical Ind. Co., Ltd.; Fujian Qingliu Dongying Chemical Co., Ltd.; Jiangsu Sanmei Chemical Ind. Co., Ltd | 48.67 |
**Disclosure**
Commerce intends to disclose the calculations performed in connection with these final results of review to interested parties 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 the notice of final results 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), Commerce has determined, and U.S. Customs and Border Protection (CBP) shall assess, antidumping duties on all appropriate entries of subject merchandise covered by this review.
For Sanmei, Commerce will calculate importer-specific assessment rates for antidumping duties, in accordance with 19 CFR 351.212(b)(1).
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 subject merchandise entered, or withdrawn from warehouse, for consumption on or after the publication date, as provided for by section 751a)(2)(C) of the Act: (1) for the Sanmei Companies, the cash deposit rate will be equal to the dumping margin established in the final results of this review; (2) for previously examined Chinese and non-Chinese exporters not listed above that maintain separate rates based on a prior completed segment of this proceeding, the cash deposit rate will continue to be the existing exporter-specific cash deposit rate; (3) for all Chinese exporters of subject merchandise that have not been found to be entitled to a separate rate, the cash deposit rate will be the rate for the China-wide entity ( *i.e.,* 267.51 percent); and (4) for all non-Chinese exporters of subject merchandise which have not received their own rate, the cash deposit rate will be the rate applicable to the Chinese exporter that supplied that non-Chinese exporter. These 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 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**
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 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 of administrative review in accordance with sections 751(a)(1) and 777(i)(1) of the Act and 19 CFR 351.221(b)(5) and 19 CFR 351.213(h)(2).
Dated March 9, 2026.
