Product classification
HS code for HCFC mixtures: 3827.32
Mixtures containing halogenated methane, ethane, propane, containing hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs) or hydrofluorocarbons (HFCs) or not, not chlorofluorocarbons (CFCs), containing substances of subheadings 2903.71 to 2903.75.
Classification of HCFC mixtures under HS 3827.32
HCFC mixtures containing specific substances from subheadings 2903.71 to 2903.75 are classified under HS code 3827.32. This classification is part of the 3827 heading, which manages mixtures of halogenated hydrocarbons. The 3827.32 subheading is used for mixtures that contain hydrochlorofluorocarbons (HCFCs), and may or may not contain perfluorocarbons (PFCs) or hydrofluorocarbons (HFCs), but must not contain chlorofluorocarbons (CFCs). The specific inclusion of substances from 2903.71 (like chlorodifluoromethane) to 2903.75 makes this code the primary destination for many common transitional refrigerant blends used in air conditioning and refrigeration systems. Classification is based on the chemical constituents of the blend. Because these substances are regulated under the Montreal Protocol, precise classification is required for import quotas and environmental reporting. This code specifically targets blends that are used as alternatives to more potent ozone-depleting substances.

Codes often confused with 3827.32
Common mistake. This code is frequently confused with HS code 3827.31, which covers mixtures containing HCFCs but specifically excludes those containing HFCs or PFCs. It is also often confused with 3827.11, which is for mixtures containing CFCs, which are much more strictly regulated and generally banned for most uses.
Top exporters and importers of HS 382732 (the code used for HCFC mixtures), 2025
In 2025, the largest exporter of HS 382732 (the code used for HCFC mixtures) in UN Comtrade data was China, with 83% of world exports; the largest importer in UN Comtrade data was South Korea, with 84% of world imports. Mexico reports $159M of its heading 3827 imports without product detail (confidential), so it may also belong among the top importers.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).

Questions about HCFC mixtures
What is the HS code for HCFC mixtures?
The HS code for HCFC mixtures is 382732 (Mixtures containing halogenated methane, ethane, propane; containing hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs) or hydrofluorocarbons (HFCs) or not, not chlorofluorocarbons (CFCs); containing substances of subheadings 2903.71 to 2903.75). The HS code for mixtures containing HCFCs (specifically from 2903.71 to 2903.75) is 3827.32.
How do I classify HCFC mixtures for customs?
HCFC mixtures is classified under HS code 382732 — Mixtures containing halogenated methane, ethane, propane; containing hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs) or hydrofluorocarbons (HFCs) or not, not chlorofluorocarbons (CFCs); containing substances of subheadings 2903.71 to 2903.75. This is a 6-digit subheading level code.
Can this code be used for pure HCFC-22?
No, pure HCFC-22 is a single chemically defined compound and is classified under HS code 2903.71.
Which countries are the top exporters of HCFC mixtures (HS 382732)?
In 2025, the top exporters of HS 382732 (the code used for HCFC mixtures) in UN Comtrade data were China ($353K, 83% of world exports), the United States ($70K) and Belgium ($845). World exports came to about $425K, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data).
