(34)A central so-called F-gas Portal should be set up and operated by the Commission to manage quota for the placing on the market of HFCs, registration of undertakings concerned, and reporting on all substances and on all equipment placed on the market, in particular where the equipment is pre-charged with HFCs that have not been placed on the market prior to charging. To ensure that only genuine traders can register in the F-gas Portal, specific conditions should be established. A valid registration in the F-gas Portal should constitute a licence, which is an essential requirement under the Protocol to monitor HFC trade and prevent illegal activities in that respect.
