HS Code 3827.31 – Mixtures containing halogenated derivatives of methane, ethane or propane; containing hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs) or hydrofluorocarbons (HFCs) or not, but not containing chlorofluorocarbons (CFCs); containing substances of su

HS code 3827.31 is the 6-digit subheading for mixtures containing halogenated derivatives of methane, ethane or propane, containing hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs) or hydrofluorocarbons (HFCs) or not, but not containing chlorofluorocarbons (CFCs), containing substances of su. It is used for R-22 refrigerant (HCFC-22), R-134a refrigerant (HFC-134a), R-410A refrigerant (HFC blend), R-404A refrigerant (HFC blend) and HFC-227ea fire suppressant.

What HS 3827.31 covers

This HS code covers mixtures containing hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs), or hydrofluorocarbons (HFCs), but explicitly excludes mixtures containing chlorofluorocarbons (CFCs). HCFCs are ozone-depleting substances, albeit less potent than CFCs, and are currently undergoing a global phase-out under the Montreal Protocol. HFCs and PFCs, while not ozone-depleting, are potent greenhouse gases subject to phase-down under the Kigali Amendment to the Montreal Protocol and other climate change regulations. These mixtures are widely traded as refrigerants, blowing agents for foams, aerosol propellants, and fire suppressants. Importers and exporters include chemical manufacturers, HVAC-R companies, and automotive suppliers. The trade is dynamic, driven by technological advancements towards lower global warming potential (GWP) alternatives and evolving environmental policies.

Covers
  • R-22 refrigerant (HCFC-22)
  • R-134a refrigerant (HFC-134a)
  • R-410A refrigerant (HFC blend)
  • R-404A refrigerant (HFC blend)
  • HFC-227ea fire suppressant
  • PFC-based heat transfer fluids
  • HCFC-141b blowing agent.
Examples
  • Chemours Freon (e.g., R-410A)
  • Honeywell Solstice (HFOs, but also HFCs)
  • Arkema Forane (e.g., R-134a)
  • Daikin HFC refrigerants.

Codes often confused with 3827.31

Common mistake. Often confused with CFC-containing mixtures (382711) if the absence of CFCs isn't confirmed, or with pure halogenated hydrocarbons (Chapter 29) if they are not mixtures. The presence of HCFCs, PFCs, or HFCs is key for proper classification and regulatory compliance.

3827.11Mixtures containing halogenated derivatives of methane, ethane or propane, not elsewhere specified or included; containing chlorofluorocarbons (CFCs), whether or not containing hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs) or hydrofluorocarbon

Top exporters and importers of HS code 382731, 2025

In 2025, the largest exporter of HS code 382731 in UN Comtrade data was China, with 77% of world exports; the largest importer in UN Comtrade data was Angola, with 27% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
