The labelling requirements only apply to F-Gas containers placed on the market and containing F-Gases. All returnable cylinders, drums etc should be labelled. As non-returnable containers are banned these requirements should not need to be applied.
However the labelling requirements do not apply to ISOtanks if these are not placed on the market. Therefore ISOtanks used to deliver F-Gases, where control remains with the supplier, need not have additional F-Gas labelling.
The Commission guidance and the implementating regulation does not require recovery cylinders/drums to be labelled where they placed on the market empty. Recovery cylinders and drums placed on the market empty are not subject to the F-Gas labelling requirements.
