Since 1 June 2019, the import and export of hydrofluorocarbons (HFCs) has been subject to an authorization requirement pursuant to Annex F of the Montreal Protocol (Annex 1.5, numbers 4.3.1 and 5.1, ORRChem). The authorization requirement serves in particular to monitor compliance with the HFC consumption planned for Switzerland in accordance with its international obligations (see diagram).

The import of these HFCs requires an import permit issued by the FOEN, which is only granted if the HFCs are intended for a permissible use or an exemption permit has been issued. The licence is granted as a general import licence (Annex 1.5, number 4.3 ORRChem).
