HCFC
In Europe, the sale and use of HCFCs (hydrochlorofluorocarbons) are governed by the European regulation 1005/2009 of 16 September 2009 about substances that deplete the ozone layer. From 1 January 2010 to 31 December 2014, only the use of non-virgin HCFCs (recycled or reclaimed) is authorised.
Outside Europe, the sale and use of HCFCs may be authorised according to the regulations in the country.
