U.S. exports of refrigerant mixtures containing 55% or more hfc-125 (pentafluoroethane), excluding hfos (HS 382762) totaled $155K in June 2026, traded with 1 country.
Last updated: June 2026 dataPentafluoroethane (HFC-125) at concentrations of 55% or more by mass — and without any hydrofluoroolefin (HFO) content — defines this subheading, which primarily captures blends such as R-125/HFC-125 neat or high-HFC-125 binary mixtures used in fire suppression and certain refrigeration applications. The explicit exclusion of HFOs is a classification boundary that separates these legacy blends from newer, lower-GWP fourth-generation refrigerant formulations. China and the Netherlands are the leading US suppliers, with China dominating upstream HFC-125 production and the Netherlands serving as a European blending and re-export hub. Chinese-origin imports are subject to Section 301 tariffs.

Adding even a small quantity of an HFO (such as HFO-1234yf or HFO-1234ze) to a blend that would otherwise qualify here shifts classification to a different subheading that specifically covers HFO-containing mixtures. Formulators and importers must verify the exact composition certificate to confirm no HFO content before declaring under 382762.
Yes. Because these blends contain HFCs subject to the EPA's HFC phasedown program under the AIM Act, importers must hold sufficient consumption allowances for the HFC content of each shipment. The allowance requirement applies regardless of the blend's country of origin.
