Candidate List

Substances of Very High Concern (SVHC)

Substances fulfilling one or more of the criteria defined in REACH Article 57 can be identified as “substances of very high concern” (SVHC).  Substances that may be designated as SVHC include: 

  • substances meeting the criteria for classification as carcinogenic, mutagenic or reprotoxic (CMR) category 1 or 2;
  • substances for which there is evidence for similar concern, such as endocrine disruptors. 
  • persistent, bioaccumulative and toxic (PBT) substances or very persistent and very bioaccumulative (vPvB) substances; or

SVHC are identified by Member States and placed on the Candidate List.  Addition of a substance to the Candidate List triggers legal obligations throughout the supply chain.


ECHA prioritizes substances on the Candidate List, to determine which substances should be subject to authorization.  Prioritization results in decisions regarding: 

  • the “sunset date” by when a substance can no more be used without authorizisation. 
  • whether or not the substance will be subject to authorization; 
  • which uses of the included substances will not need authorization (e.g. because sufficient controls established by other legislation are already in place); and

REACH contains notification and communication requirements for SVHC in articles.  Suppliers of Candidate List substances and preparations containing them need to provide customers with safety data sheets. 

ECHA publishes a registry of intentions that identifies substances which might be listed as SVHC (before they are included in the Candidate List).
