HFC-143a (1,1,1-trifluoroethane) is a high-global-warming-potential component most commonly found in R-404A and R-507A blends, which are widely used in commercial refrigeration and low-temperature freezer applications. Blends meeting the 15% or more by mass threshold for HFC-143a are classified under tariff line 3827610000 and are subject to EPA SNAP program oversight. Mexico is the leading US supplier of these blends, followed by Japan and China, reflecting both proximity-driven logistics and established fluorochemical manufacturing capacity in those markets. Importers should be aware that Section 301 measures apply to Chinese-origin HFC blends.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
R-404A (a ternary blend of HFC-125, HFC-143a, and HFC-134a) and R-507A (a binary blend of HFC-125 and HFC-143a) are the most prevalent commercial refrigerants that meet the 15% or more HFC-143a threshold. Both are widely used in supermarket display cases, transport refrigeration, and industrial freezing systems.
Yes. The American Innovation and Manufacturing (AIM) Act authorizes EPA to phase down HFC production and consumption through an allowance system. Importers of HFC blends containing HFC-143a must hold or acquire EPA consumption allowances, and the allowance requirements have tightened progressively since 2022. Compliance with the allowance program is a prerequisite for lawful importation.
