Hydrofluorocarbon Blends From the People's Republic of China: Preliminary Results of the Antidumping Duty Administrative Review and Preliminary Determination of No Shipments; 2023-2024
Published Date: 2/10/2026
Notice
Summary
The U.S. Department of Commerce found that Chinese companies sold hydrofluorocarbon blends at unfairly low prices from August 2023 to July 2024. One company didn’t ship any products during this time. This means some importers might face extra duties soon, and people involved have a chance to share their thoughts before final decisions.
Analyzed Economic Effects
6 provisions identified: 0 benefits, 5 costs, 1 mixed.
Preliminary 182.61% Dumping Margin
Commerce preliminarily found that sales of hydrofluorocarbon blends from China were at less than normal value for the period August 1, 2023 through July 31, 2024. Commerce preliminarily assigned a weighted-average dumping margin of 182.61% to Zhejiang Sanmei Chemical Industry Co., Ltd.; Jiangsu Sanmei Chemical Ind. Co., Ltd.; and Fujian Qingliu Dongying Chemical Ind. Co., Ltd. If finalized, importers of merchandise from these companies may face antidumping duties equal to that percentage.
China-Wide 216.37% Duty Rate Applies
Commerce states the China-wide antidumping rate of 216.37% remains in effect and will be used to liquidate entries for companies it treats as part of the China-wide entity (the companies listed in Appendix II) for the period August 1, 2023 through July 31, 2024. Importers of entries from those Appendix II companies will be assessed duties at the 216.37% China-wide rate when Commerce issues assessment instructions.
Cash Deposit Rules Effective at Publication
For shipments of the subject merchandise entered, or withdrawn from warehouse, for consumption on or after the publication date (February 10, 2026), Commerce will require cash deposits: for Sanmei, a deposit equal to the weighted-average dumping margin established in the final results; for Chinese exporters without a separate rate, the China-wide rate of 216.37%; and for non-Chinese exporters without their own rate, the rate of the Chinese exporter that supplied them. These cash deposit requirements will remain in effect until further notice.
Assessment and Liquidation Instructions
Upon completion of the review, Commerce will instruct U.S. Customs and Border Protection (CBP) to assess antidumping duties on appropriate entries based on the final results; Commerce intends to issue assessment instructions no earlier than 35 days after publication of the final results. Commerce will instruct CBP to liquidate entries for companies in the China-wide entity at 216.37% and, where an exporter had no shipments, to liquidate suspended entries at the cash deposit rate in effect at the time of entry.
Importer Reimbursement Certificate Required
This notice reminds importers of their obligation under 19 CFR 351.402(f) to file a certificate regarding reimbursement of antidumping duties prior to liquidation of relevant entries. If importers fail to file the certificate, Commerce may presume reimbursement occurred and assess double antidumping duties.
No-Shipments Finding for Zhejiang Yonghe
Zhejiang Yonghe Refrigerant Co., Ltd. reported no shipments of subject merchandise to the United States during the period of review, and Commerce preliminarily determined it had no shipments for August 1, 2023 through July 31, 2024. Commerce will not rescind the review for this company and will liquidate any suspended entries that entered under its CBP case number at the cash deposit rate required at the time of entry.
