SVHC

Substances of Very High Concern

Clear definitions for marketplaces, manufacturers, and importers.

What it means

SVHCs are substances classified under REACH as being of very high concern — for example because they are carcinogenic, mutagenic, toxic to reproduction, or persistent and bioaccumulative. ECHA maintains a continuously updated Candidate List. Suppliers must inform downstream users if an article contains more than 0.1% by weight of an SVHC. The list currently contains over 230 substances.
