Executive Summary

Commerce concluded its 2024-2025 administrative review of the AD order on 1,1,1,2-Tetrafluoroethane (R-134a) from China (case A-570-044), finding that mandatory respondent Sanmei and 23 additional companies failed to establish separate-rate eligibility and are thus subject to the China-wide entity rate. All reviewed companies will face the full China-wide AD duty going forward.
