HS code · 6-digit subheading

HS Code 3827.63 – Mixtures containing halogenated derivatives of methane, ethane or propane; containing other hydrofluorocarbons (HFCs) but not containing chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs); other mixtures not included in the subheadings above,

HS code 3827.63 is the 6-digit subheading for mixtures containing halogenated derivatives of methane, ethane or propane, containing other hydrofluorocarbons (HFCs) but not containing chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs), other mixtures not included in the subheadings above,. It is used for R-134a blends, automotive AC refrigerants, domestic refrigeration blends, aerosol propellants and foam blowing agents.

What HS 3827.63 covers

This HS code covers mixtures of halogenated derivatives of methane, ethane, or propane containing hydrofluorocarbons (HFCs), but not CFCs or HCFCs, where 1,1,1,2-tetrafluoroethane (HFC-134a) constitutes 40% or more by mass. HFC-134a is one of the most widely used HFCs, serving as a refrigerant in automotive air conditioning, domestic refrigerators, and chillers, as well as a propellant in aerosols and a blowing agent for foams. Its international trade is substantial, driven by these diverse applications across various industries. While it is non-ozone-depleting, its high global warming potential means it is also subject to phase-down under the Kigali Amendment, leading to a global transition towards lower-GWP alternatives in many sectors.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
