SUPPLEMENTARY INFORMATION:

Background

On February 10, 2026, we published the Preliminary Results and invited interested parties to comment.^[1] We received timely case and rebuttal briefs from the American HFC Coalition (the petitioner) and Zhejiang Sanmei Chemical Industry Co., Ltd. (Sanmei).^[2] On May 20, 2026, and July 2, 2026, Commerce extended the deadline of the final results of this administrative review, in accordance with section 751(a)(3)(A) of the Tariff Act of 1930, as amended (the Act), and 19 CFR 351.213(h)(2); ^[3] accordingly, the deadline is now July 24, 2026.

For details regarding the events that occurred since the Preliminary Results, see the Issues and Decision Memorandum.^[4] 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). ACCESS is available to registered users at https://access.trade.gov. In addition, a complete version of the Issues and Decision Memorandum can be accessed directly at https://access.trade.gov/​frnotices. Commerce conducted this administrative review in accordance with section 751 of the Act.

Scope of the Order ^[5]

The products covered by this Order are HFC blends from China. For a complete description of the scope of the Order, see the Issues and Decision Memorandum.

Analysis of Comments Received

We addressed all the issues raised in the case and rebuttal briefs in the Issues and Decision Memorandum. A list of the issues that parties raised is provided in Appendix I of this notice.

Final Determination of No Shipments

In the Preliminary Results, we determined that Zhejiang Yonghe did not have shipments of subject merchandise during the POR.^[6] We received no comments regarding Zhejiang Yonghe from interested parties. Therefore, we continue to find that Zhejiang Yonghe had no shipments of subject merchandise during the POR and we will issue appropriate liquidation instructions regarding this company consistent with our “automatic assessment” clarification for these final results.^[7]

( printed page 48080)

Separate Rate

In the Preliminary Results, we found that that Sanmei, the only company individually examined in this review, is eligible to receive a separate rate. For the final results, we continue to find that Sanmei has demonstrated its eligibility for a separate rate in this review.

China-Wide Entity

Under Commerce's policy regarding conditional review of the China-wide entity,^[8] 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, the entity is not under review, and the entity's rate ( i.e., 216.37 percent) ^[9] is not subject to change. Commerce considers the companies under review listed in Appendix II to this notice, which did not file a separate rate application or demonstrate separate rate eligibility, to be part of the China-wide entity.

Final Results of Review

Commerce determines that the following estimated weighted-average dumping margin exists for the period August 1, 2023, through July 31, 2024:

Disclosure

Normally, Commerce discloses to interested parties the calculations of the final results of an administrative review within five days of a public announcement or, if there is no public announcement, within five days of the date of publication of the final results in the Federal Register , in accordance with 19 CFR 351.224(b). However, because 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), Commerce will determine, and U.S. Customs and Border Protection (CBP) shall assess, antidumping 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).

For Sanmei, Commerce will calculate importer-specific assessment rates for antidumping duties, in accordance with 19 CFR 351.212(b)(1). Where the respondent reported reliable entered values, Commerce intends to calculate importer-specific ad valorem assessment rates by aggregating the amount of dumping calculated for all U.S. sales to the importer and dividing this amount by the total entered value of the merchandise sold to the importer.^[10] Where the respondent did not report entered values, Commerce will calculate importer-specific assessment rates by dividing the amount of dumping for reviewed sales to the importer by the total quantity of those sales. Commerce will calculate an estimated ad valorem importer-specific assessment rate to determine whether the per-unit assessment rate is de minimis ( i.e., 0.50 percent or below); however, Commerce will use the per-unit assessment rate where entered values were not reported.^[11] Where an importer-specific ad valorem assessment rate is not zero or de minimis, Commerce will instruct CBP to collect the appropriate duties at the time of liquidation. Where either the respondent's weighted-average dumping margin is zero or de minimis, or an importer-specific ad valorem assessment rate is zero or de minimis, Commerce will instruct CBP to liquidate appropriate entries without regard to antidumping duties.^[12]

Pursuant to Commerce's assessment practice,^[13] for entries that were not reported in the U.S. data submitted by Sanmei, we will instruct to CBP to liquidate such entries at the China-wide rate ( i.e., 216.37 percent).^[14] Additionally, where Commerce determined that an exporter under review had no shipments of subject merchandise to the United States during the POR, any suspended entries of subject merchandise that entered under that exporter's CBP case number during the POR will be liquidated at the weighted-average dumping margin assigned to the China-wide entity.

For the companies listed in Appendix II found to be part of the China-wide entity, we will instruct CBP to liquidate all entries of subject merchandise during the POR exported by these companies at the China-wide assessment rate. Further, for Zhejiang Yonghe, the company determined to have no shipments, we will instruct CBP to assess antidumping duties on all appropriate entries at a rate equal to the cash deposit rate of 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).

Cash Deposit Requirements

The following cash deposit requirements will be effective for shipments of the subject merchandise entered, or withdrawn from warehouse, for consumption on or after the publication date for the final results of review, as provided for by section 751(a)(2)(C) of the Act: (1) for Sanmei, the cash deposit rate will be the rate established in the final results of this review; (2) for previously investigated or reviewed exporters not under review that have separate rates, the cash deposit rate will continue to be the existing exporter-specific rate published for the most recently-completed segment of this proceeding; (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., 216.37 percent); and (4) for all exporters of subject merchandise which are not located in China and have not received their own rate, the cash deposit rate will be the rate applicable to the Chinese exporter(s) that supplied that non-China exporter. 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 and/or countervailing ( printed page 48081) 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 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.

Administrative Protective Order

This notice also serves as a reminder to parties subject to an 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 violation which is subject to sanction.

Notification to Interested Parties

We are issuing these final results of administrative review and publishing this notice in accordance with sections 751(a)(1) and 777(i)(1) of the Act, and 19 CFR 351.213(h)(1) and 351.221(b)(5).
