Perfluorocarbon-based refrigerant and specialty gas blends that contain no chlorofluorocarbons or hydrochlorofluorocarbons occupy a distinct regulatory niche under the EPA's Significant New Alternatives Policy (SNAP) program, which evaluates substitutes for ozone-depleting substances. PFC mixtures are potent greenhouse gases with very high global warming potentials, making them subject to EPA reporting and, in some applications, use restrictions. Importers should verify that blends are correctly distinguished from HFC-only mixtures, as misclassification between the 3827 subheadings can trigger compliance issues. The single US tariff line for this heading is 3827590000.

The key distinction is the presence of perfluorocarbons (fully fluorinated, no hydrogen atoms) versus hydrofluorocarbons (partially fluorinated). If a blend contains PFCs but no CFCs or HCFCs, it falls under 382759 regardless of whether HFCs are also present; blends containing only HFCs without PFCs are classified in the more specific HFC subheadings within heading 3827.
PFC mixtures are subject to EPA greenhouse gas reporting requirements under the Mandatory Reporting Rule if import thresholds are met. Additionally, EPA's SNAP program may restrict or prohibit certain PFC blends in specific end-use sectors such as refrigeration and foam blowing, so importers should confirm the intended application is an approved use before entry.
