Preliminary Results on R-134a Antidumping Review from China
Published Date: 3/12/2026
Notice
Summary
The U.S. Department of Commerce took a close look at a chemical called R-134a from China and found that one big group of companies, including Zhejiang Sanmei and others, are treated as one big team for trade rules. They also decided to stop reviewing three companies for now. This means some import duties might change starting March 12, 2026, affecting businesses that trade this chemical.
Analyzed Economic Effects
4 provisions identified: 0 benefits, 4 costs, 0 mixed.
China-wide Duty Rate Applied (167.02%)
Commerce preliminarily found that Zhejiang Sanmei (the Sanmei single entity) and 23 other named Chinese companies are part of the China-wide entity and will be subject to the China-wide antidumping rate of 167.02 percent for R-134a for the period April 1, 2024 through March 31, 2025. Because no party requested a review of the China-wide entity, that 167.02 percent rate is not being changed in this review.
Cash Deposit Rules Effective March 12, 2026
For shipments entered or withdrawn for consumption on or after March 12, 2026, cash deposit rules apply: (1) previously examined exporters not under review keep their existing exporter-specific deposit rate; (2) Chinese exporters that have not established a separate rate must post the China-wide deposit rate of 167.02 percent; and (3) non-Chinese exporters without their own rate must post the deposit rate of the Chinese exporter that supplied them.
Review Rescinded for Three Firms; Duties Assessed
Commerce rescinded the administrative review for Jiangsu Bluestar Green Technology Co., T.T. International Co., and Weitron International Refrigeration Equipment (Kunshan) Co. Ltd. because they had no suspended entries during April 1, 2024–March 31, 2025; Commerce will instruct U.S. Customs and Border Protection to assess antidumping duties on appropriate entries at rates equal to the cash deposit required at time of entry. Commerce intends to issue assessment instructions no earlier than 35 days after this notice's publication.
Importer Reimbursement Certificate Requirement
Importers must file a certificate about reimbursement of antidumping duties before liquidation of the relevant entries for the April 1, 2024–March 31, 2025 period. If an importer does not file the certificate, Commerce may presume reimbursement occurred and assess double antidumping duties.
