HS code · 6-digit subheading

HS Code 3827.64 – 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 3827.64 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-32 blends, R-410A (contains HFC-32), R-407C (contains HFC-32), R-454B and R-452B.

What HS 3827.64 covers

This HS code specifies mixtures of halogenated derivatives of methane, ethane, or propane containing hydrofluorocarbons (HFCs), but not CFCs or HCFCs, where difluoromethane (HFC-32) makes up 30% or more by mass. HFC-32 is a key component in next-generation, lower-GWP HFC blends and is increasingly used as a pure refrigerant, especially in residential and light commercial air conditioning. Its trade is experiencing rapid growth as the HVAC&R industry transitions away from higher-GWP HFCs like R-410A. Importers and exporters are primarily chemical manufacturers and HVAC equipment producers seeking more environmentally friendly and energy-efficient refrigerant solutions to meet global environmental regulations and market demand.

Codes often confused with 3827.64

Common mistake. Can be confused with other HFC mixtures (e.g., 382765) if the specific HFC-32 content threshold is not met. Pure HFC-32 (2903.39) should not be classified here.

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).
