HS Code for PFC mixtures

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.

Products Included

• Refrigerant mixtures containing HCFC-22
• Solvent blends containing perfluorocarbons and hydrochlorofluorocarbons
• Fire extinguishing preparations containing substances of subheadings 2903.71 to 2903.75
• Foam-blowing agent mixtures with HFC and HCFC components

Common Misclassification

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).

FAQ

What is the HS code for PFC mixtures?

The HS code for mixtures containing PFCs, HFCs, or HCFCs, specifically those containing substances of subheadings 2903.71 to 2903.75, is 3827.32.

Does this code include pure perfluorocarbons?

No, pure perfluorocarbons are classified as separate chemically defined compounds under Chapter 29, specifically within heading 2903.
