U.S. imports of mixtures containing chlorofluorocarbons (cfcs) (HS 382711) totaled $27K in June 2026, traded with 1 country.
Mixtures Containing Chlorofluorocarbons (CFCs) imports of $27K in June 2026 ran 37% above the year-to-date monthly average of $20K.
CFC-containing refrigerant blends are among the most tightly regulated substances under the Montreal Protocol, and US imports require EPA compliance under the Clean Air Act's ozone-depleting substance (ODS) provisions before entry is permitted. The single US tariff line (3827110000) captures all such mixtures regardless of whether they also contain HCFCs, PFCs, or HFCs, making correct classification critical when blends contain multiple halogenated components. Canada is the leading supplier, with South Korea also a notable source. Importers should be prepared to document allowance allocations and verify that the exporting country's production is consistent with its Montreal Protocol phase-out schedule.

Importers must hold valid EPA allowances under the Clean Air Act's ODS import program. Shipments without proper allowance documentation can be refused entry, and the EPA may require advance notification depending on the substance and quantity.
The presence of CFCs controls classification: a mixture that contains CFCs falls under 382711 regardless of whether it also contains HCFCs, PFCs, or HFCs. Only blends that are entirely free of CFCs would be classified under the HCFC-specific headings (382731, 382732, or 382739).
