Q178. Are importers of HFCs required to obtain EPA approval before importing the HFCs into the U.S.?
A178. Importers of hydrofluorocarbons (HFCs) are not required to obtain approval from EPA before importing the HFCs. However, under EPA's Greenhouse Gas Reporting Rule (40 CFR Part 98), importers are required to annually report their bulk imports and exports of HFCs and other greenhouse gases if their total combined bulk imports of fluorinated greenhouse gases (fluorinated GHGs), nitrous oxide (N2O), and carbon dioxide (CO2) exceed 25,000 metric tons of carbon dioxide equivalents (CO2e) per year. (They are also required to report if their total annual exports of these gases exceed 25,000 metric tons of carbon dioxide equivalents (CO2e) per year.) Fluorinated GHGs include HFCs, perfluorocarbons (PFCs), sulfur hexafluoride (SF6), nitrogen trifluoride (NF3), hydrofluoroethers (HFEs), and others. For purposes of the Greenhouse Gas Reporting Rule, fluorinated GHGs exclude chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), which are regulated under EPA's stratospheric ozone protection regulations (40 CFR Part 82).
