China's R-134a Fridge Gas Hit with US Antidumping Duties After Delays
Published Date: 4/2/2026
Notice
Summary
The U.S. Department of Commerce found that China sold 1,1,1,2-Tetrafluoroethane (R-134a) in the U.S. for less than fair value from April 2023 to March 2024. This means importers might face new antidumping duties starting April 2, 2026, to keep things fair for American businesses. Deadlines were pushed back due to government shutdowns, but now the final results are in and ready to roll!
Analyzed Economic Effects
4 provisions identified: 0 benefits, 4 costs, 0 mixed.
Huge Duty: Sanmei Entity 173.90%
If you import R-134a from Zhejiang Sanmei Chemical Ind. Co. Ltd., Jiangsu Sanmei Chemical Ind. Co., Ltd., or Fujian Qingliu Dongying Chemical Ind. Co. Ltd., Commerce found a weighted-average dumping margin of 173.90% for April 1, 2023 through March 31, 2024. Commerce will assess antidumping duties on entries covered by this review, and the company-specific cash deposit rate for shipments entered or withdrawn for consumption on or after April 2, 2026 will equal this 173.90% rate.
China-Wide Rate Set at 167.02%
If you import R-134a from a China exporter that has not been found to have a separate rate, the cash deposit rate will be the China-wide entity rate of 167.02% for shipments entered or withdrawn for consumption on or after April 2, 2026. This China-wide rate also remains unchanged for purposes of this review.
Unreported Sanmei Sales Liquidated at 167.02%
For sales that Sanmei did not report in its U.S. sales data during the review, Commerce will instruct U.S. Customs and Border Protection to liquidate the associated entries at the China-wide entity rate of 167.02%.
File Reimbursement Certificate or Risk Double Duties
If you import the subject merchandise, you must file a certificate about whether antidumping duties were reimbursed before liquidation of the relevant entries for the period April 1, 2023 through March 31, 2024. If you do not comply, Commerce may presume reimbursement occurred and assess double antidumping duties.
