Notice
Summary
The U.S. Department of Commerce finished reviewing imports of a chemical called R-134a from China for 2024-2025. They decided that Zhejiang Sanmei and 23 other companies won’t get special treatment and will be treated as part of a bigger China-wide group for duties. This means importers might face consistent antidumping duties starting June 22, 2026, keeping trade fair and prices steady.

167.02% Duty Applied to Listed Exporters
If you import R-134a that was exported during April 1, 2024 through March 31, 2025 by any company listed in the Appendix, U.S. Customs will be instructed to apply an ad valorem antidumping assessment rate of 167.02 percent to those entries. This assessment instruction relates to entries covered by the administrative review and is effective as described in the notice published June 22, 2026.
167.02% Cash Deposit Requirement
For shipments of R-134a entered or withdrawn for consumption on or after June 22, 2026, China exporters that were not found entitled to a separate rate must now post a cash deposit equal to the China-wide rate of 167.02 percent. The notice states these cash deposit requirements will remain in effect until further notice.
Importer Reimbursement Certificate Reminder
If you are an importer of the subject merchandise, you must file a certificate about whether antidumping duties were reimbursed before liquidation of entries from the reviewed period. The notice warns that failing to file this certificate could lead Commerce to presume reimbursement occurred and could trigger assessment of double antidumping duties.
