HS code for 1,1,1-Trifluoroethane mixtures: 3827.61
Mixtures containing halogenated derivatives of methane, ethane or propane, containing other hydrofluorocarbons (HFCs) but not containing chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs), containing 15% or more by mass of 1,1,1-trifluoroethan.
Classification of 1,1,1-Trifluoroethane mixtures under HS 3827.61
HS code 3827.61 is designated for mixtures containing hydrofluorocarbons (HFCs) where 1,1,1-trifluoroethane (also known as HFC-143a) accounts for 15% or more of the total mass. This classification is found in Chapter 38 (Miscellaneous chemical products) under heading 3827, which was created to monitor mixtures of halogenated derivatives that contribute to global warming. To fall under this specific code, the mixture must not contain any chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs). These mixtures are predominantly used as refrigerants in commercial refrigeration systems and as propellants in aerosols. The 15% mass threshold is a critical technical requirement; if the concentration of 1,1,1-trifluoroethane is lower, the mixture may fall under a different subheading such as 3827.62. Classification requires a detailed chemical breakdown, often found in a Safety Data Sheet (SDS), to confirm the percentage of HFC-143a and the absence of ozone-depleting substances regulated under other subheadings.

Codes often confused with 3827.61
Common mistake. A common misclassification occurs with HS code 3827.62, which is for other HFC mixtures that do not meet the 15% threshold of 1,1,1-trifluoroethane. It is also frequently confused with 2903.39, which covers pure HFC-143a as a single chemically defined compound. Furthermore, if the mixture contains even a trace amount of HCFCs, it must be moved to subheadings 3827.31 through 3827.39, which take precedence over the HFC-only codes.
Top exporters and importers of HS 382761 (the code used for 1,1,1-Trifluoroethane mixtures), 2025
In 2025, the largest exporter of HS 382761 (the code used for 1,1,1-Trifluoroethane mixtures) in UN Comtrade data was China, with 71% of world exports; the largest importer in UN Comtrade data was Russia, with about 7.8% 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 1,1,1-Trifluoroethane mixtures
What is the HS code for 1,1,1-Trifluoroethane mixtures?
The HS code for 1,1,1-Trifluoroethane mixtures is 382761 (Mixtures containing halogenated derivatives of methane, ethane or propane; containing other hydrofluorocarbons (HFCs) but not containing chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs); containing 15% or more by mass of 1,1,1-trifluoroethan). The HS code for mixtures containing 15% or more by mass of 1,1,1-trifluoroethane (HFC-143a), without CFCs or HCFCs, is 3827.61.
How do I classify 1,1,1-Trifluoroethane mixtures for customs?
1,1,1-Trifluoroethane mixtures is classified under HS code 382761 — Mixtures containing halogenated derivatives of methane, ethane or propane; containing other hydrofluorocarbons (HFCs) but not containing chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs); containing 15% or more by mass of 1,1,1-trifluoroethan. This is a 6-digit subheading level code.
What happens if the mixture contains less than 15% 1,1,1-trifluoroethane?
If the mixture contains HFCs but the 1,1,1-trifluoroethane content is less than 15% by mass, it is typically classified under HS code 3827.62 or another relevant subheading in the 3827 group.
Which countries are the top exporters of 1,1,1-Trifluoroethane mixtures (HS 382761)?
In 2025, the top exporters of HS 382761 (the code used for 1,1,1-Trifluoroethane mixtures) in UN Comtrade data were China ($185M, 71% of world exports), Slovakia ($13M) and Italy ($7.7M).
