The SVHC Candidate List is published and updated twice a year by the European Chemicals Agency (ECHA). Listing carries immediate legal duties even before a substance is added to the REACH authorisation list: when an SVHC is present in an article above 0.1% weight by weight, suppliers must pass that information down the supply chain and notify ECHA's SCIP database.
For a Digital Product Passport this matters because substance-of-concern data is a regulated field across product groups under ESPR. Knowing which SVHCs a product contains, and at what concentration, is the prerequisite for both the SCIP notification and any DPP disclosure on hazardous substances.
Frequently asked
What is the 0.1% SVHC threshold?
When an SVHC on the ECHA Candidate List is present in an article above 0.1% weight by weight, REACH duties trigger: communication of safe-use information down the supply chain, a response to consumer requests within 45 days, and a SCIP notification to ECHA.
Is the SVHC list the same as the REACH Authorisation List?
No. The Candidate List is a precursor — substances on it may later be moved to Annex XIV (the Authorisation List), which then bans their use without specific authorisation. Candidate-List listing already carries notification and communication duties on its own.
