ECHA regularly assesses the substances from the Candidate List to determine which ones should be included in the Authorisation List as a priority.
This prioritisation is based primarily on information in registration dossiers on uses and volumes of the substance in the scope of authorisation. It also takes into account information received during the SVHC consultation or other sources, if relevant.
Priority is given to substances with :
PBT or vPvB properties
Additional aspects relevant for the recommendation can be considered.
