Product classification
HS code for HFC 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 HFC mixtures under HS 3827.61
HFC mixtures containing 15% or more by mass of 1,1,1-trifluoroethane (HFC-143a) are classified under HS code 3827.61. This classification falls under Chapter 38, which covers miscellaneous chemical products, rather than Chapter 29, because the product is a mixture of different chemical substances rather than a single chemically defined compound. Heading 3827 was introduced in the 2022 HS update to specifically categorize mixtures containing hydrofluorocarbons (HFCs), which are potent greenhouse gases. The subheading 3827.61 is specifically for mixtures that do not contain chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs) but do contain a significant concentration of HFC-143a. This classification is vital for the implementation of the Kigali Amendment to the Montreal Protocol, which aims to phase down the production and consumption of HFCs globally.

Codes often confused with 3827.61
Common mistake. These mixtures are often misclassified under 3827.62 through 3827.69, which cover other HFC mixtures with different chemical compositions or lower concentrations of specific HFCs. Before 2022, these were often classified under 3824.78. Another common error is attempting to classify the mixture under the HS code of its primary component in Chapter 29 (such as 2903.39). However, General Interpretative Rule 1 and the notes to Chapter 29 dictate that mixtures must be classified in Chapter 38.
Top exporters and importers of HS 382761 (the code used for HFC mixtures), 2025
In 2025, the largest exporter of HS 382761 (the code used for HFC 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 HFC mixtures
What is the HS code for HFC mixtures?
The HS code for HFC 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).
How do I classify HFC mixtures for customs?
HFC mixtures is classified under HS code 382761 โ 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 is the HS code for R-404A?
R-404A is typically classified under HS code 3827.61 because it contains more than 15% HFC-143a.
Why was the HS code for HFC mixtures changed recently?
The HS 2022 amendments created heading 3827 to better track HFCs and HFC mixtures for environmental monitoring under the Kigali Amendment.
Which countries are the top exporters of HFC mixtures (HS 382761)?
In 2025, the top exporters of HS 382761 (the code used for HFC mixtures) in UN Comtrade data were China ($185M, 71% of world exports), Slovakia ($13M) and Italy ($7.7M). World exports came to about $261M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
Which countries are the top importers of HFC mixtures (HS 382761)?
In 2025, the top importers of HS 382761 (the code used for HFC mixtures) in UN Comtrade data were Russia (about $19M, 7.8% of world imports), India ($19M) and Slovakia ($17M). World imports came to about $244M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Mexico reports $159M of its heading 3827 imports without product detail (confidential), so it may also belong among the top importers.
Is the HS code for HFC mixtures the same in all countries?
The base HS code 382761 for HFC mixtures is internationally standardized for the first 6 digits across 200+ countries. Individual countries may add additional digits for national tariff lines and specific classifications.
What is the NCM code for HFC mixtures in Brazil?
In Brazil, HFC mixtures (HS 382761) is classified under NCM 3827.61.00.
