U.S. imports of refrigerant mixtures containing 20% or more hfc-32 and 20% or more hfc-125, nesoi (HS 382765) totaled $26K in May 2026, traded with 1 country.
Refrigerant Mixtures Containing 20% or More HFC-32 and 20% or More HFC-125, NESOI imports of $26K in May 2026 ran 206% above the year-to-date monthly average of $9K.
Last updated: May 2026 dataDifluoromethane (HFC-32) and pentafluoroethane (HFC-125) together at these minimum thresholds define a subheading that captures blends such as R-410A variants and certain ternary mixtures used in air-conditioning and heat-pump systems, provided they are not already covered by a more specific subheading. India and Canada are the primary US suppliers under this heading. Canadian-origin shipments may benefit from USMCA treatment, while Indian-origin goods are assessed at MFN rates. EPA AIM Act allowance requirements apply to all imports, and the phasedown schedule for high-GWP HFC blends makes supply-chain planning increasingly important for HVAC distributors.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes — classification within heading 3827 follows a hierarchy of specificity. If the blend also meets the threshold for the 55%-or-more HFC-125 subheading (382762) or another more specific provision, that subheading takes precedence. The NESOI designation on 382765 means it applies only when no more specific subheading covers the blend's composition.
EPA's HFC phasedown under the AIM Act progressively reduces the total allowable consumption of high-GWP HFCs, including HFC-32 and HFC-125. Importers and distributors should track the annual allowance allocation schedule, as tightening caps can constrain import volumes and incentivize transition to lower-GWP alternatives such as R-32 neat or HFO-containing blends.
