Product classification
HS code for PFC 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 PFC mixtures under HS 3827.32
The classification of PFC mixtures under HS code 3827.32 is a result of the 2022 amendments to the Harmonized System, which sought to provide greater granularity for substances with high global warming potential. This code specifically addresses mixtures containing halogenated derivatives of methane, ethane, or propane. To be classified here, the mixture must contain hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs), or hydrofluorocarbons (HFCs). Furthermore, it must specifically contain substances listed in subheadings 2903.71 to 2903.75, which include chemicals like chlorodifluoromethane (HCFC-22) or various isomers of tetrachlorofluoroethanes. The classification is driven by General Interpretative Rule (GRI) 1 and 6, focusing on the chemical constituents of the mixture. These products are primarily used in industrial refrigeration systems, air conditioning units, and as specialized solvents. Because these mixtures are often subject to international environmental treaties like the Montreal Protocol, precise classification is mandatory for regulatory compliance and environmental monitoring. The mixtures must not contain chlorofluorocarbons (CFCs) to remain under this specific subheading, as those are categorized under different subheadings within heading 3827. The technical nature of these chemicals requires laboratory analysis to confirm the presence of specific halogenated hydrocarbons before final classification can be determined.

Codes often confused with 3827.32
Common mistake. PFC mixtures are frequently confused with HS code 3824.71 through 3824.79, which were the previous classifications for these mixtures prior to the 2022 HS update. Additionally, they may be misclassified under 2903.71 to 2903.79 if the importer assumes the product is a pure chemical rather than a mixture. Another common error is using 3827.11, which is reserved specifically for mixtures containing chlorofluorocarbons (CFCs).
Top exporters and importers of HS 382732 (the code used for PFC mixtures), 2025
In 2025, the largest exporter of HS 382732 (the code used for PFC 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 PFC mixtures
What is the HS code for PFC mixtures?
The HS code for PFC 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 PFCs, HFCs, or HCFCs, specifically those containing substances of subheadings 2903.71 to 2903.75, is 3827.32.
How do I classify PFC mixtures for customs?
PFC 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.
