Definition#

An SVHC is a substance identified under REACH as having serious effects on human health or the environment. Identified SVHCs go on the Candidate List, which ECHA maintains and updates roughly twice a year.

Key point

Above 0.1% in an article, an SVHC triggers communication (REACH Article 33), possible ECHA notification, and a SCIP entry. Browse them in the searchable Candidate List.

What qualifies a substance#

  • CMR: carcinogenic, mutagenic or toxic to reproduction.
  • PBT / vPvB: persistent, bioaccumulative and toxic (or very persistent and very bioaccumulative).
  • Equivalent concern, for example endocrine disruptors.

Why it matters in products#

When an article contains a Candidate List SVHC above 0.1% by weight, several duties can apply:

  • communication down the supply chain (REACH Article 33),
  • notification to ECHA (Article 7(2)),
  • a submission to the SCIP database.
