Substances of Very High Concern (SVHC)
Definition
Substances of very high concern are chemicals meeting the EU REACH Regulation's most serious hazard criteria: carcinogenic, mutagenic or toxic for reproduction (CMR); persistent, bioaccumulative and toxic (PBT); very persistent and very bioaccumulative (vPvB); or of equivalent concern, such as endocrine disruptors. Identified SVHCs are placed on the Candidate List, triggering supply chain communication duties, and may be moved to the Authorisation List, after which their use requires specific authorisation — a mechanism designed to drive substitution.

Overview
How it is used
The concept structures chemicals compliance, product material disclosure, restricted substances lists in manufacturing, and green chemistry substitution programmes.
Why it matters
SVHC is where chemical hazard becomes market signal — the regulatory engine of safer materials in Europe and, by supply chain contagion, beyond.
