Once a substance has been officially identified in the EU as being of very high concern, it will be added to a list (the Candidate List). This list is available on ECHA's website, and shows consumers and industry which chemicals are identified as SVHCs. Substances placed on the Candidate List can then move to another list (the Authorisation List). This means that, after a given date, companies will not be allowed to place the substance on the market or to use it, unless they have been given prior authorisation to do so by ECHA. One of the main aims of this listing process is to phase out SVHCs wherever possible.
