3827.11.00.00 - Containing chlorofluorocarbons (CFCs), whether or not containing hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs) or hydrofluorocarbons (HFCs)

This HTS category, 3827.11.00.00, encompasses mixtures and products that contain chlorofluorocarbons (CFCs) as a primary component. Crucially, the presence of other halogenated hydrocarbons, such as hydrochlorofluorocarbons (HCFCs), perfluorocarbons (PFCs), or hydrofluorocarbons (HFCs), does not preclude classification under this heading, provided CFCs are also present. These mixtures are typically found in specialized applications, often related to refrigerants, propellants, or cleaning agents, though their use has been significantly restricted due to environmental regulations.

This classification is distinct from its siblings by the specific identification of chlorofluorocarbons (CFCs) as a defining constituent. For instance, HTS code 3827.12.00.00 covers mixtures *only* containing hydrobromofluorocarbons (HBFCs), while 3827.13.00.00 is for those containing carbon tetrachloride, and 3827.14.00.00 pertains to those containing 1,1,1-trichloroethane. The presence of CFCs is the determining factor for classification under 3827.11.00.00.

As this is a leaf node within the HTS structure, there are no further subcategories for this specific classification. Therefore, the focus for classification purposes rests entirely on the accurate identification and quantification of CFCs within the mixture, alongside any other specified halogenated hydrocarbons. Importers and exporters must carefully review the chemical composition of their products to ensure correct adherence to this specific tariff line, particularly considering the stringent controls on ozone-depleting substances.
