The U.S. Department of Commerce (Commerce) determines that certain exporters of hydrofluorocarbon blends (HFC blends) from the People's Republic of China (China) sold subject merchandise at less than normal value during the period of review (POR), August 1, 2023, through July 31, 2024. Further, we also determine that Zhejiang Yonghe Refrigerant Co., Ltd. (Zhejiang Yonghe) had no shipments of subject merchandise to the United States during the POR. Final Determination of No ShipmentsIn the Preliminary Results, we determined that Zhejiang Yonghe did not have shipments of subject merchandise during the POR. For the final results, we continue to find that Sanmei has demonstrated its eligibility for a separate rate in this review. 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.
