Substance of very high concern

[3] It is expected that industries operating in EU member states abide by the regulations of REACH and submit chemicals for consideration when appropriate.

[6][7] A substance may be proposed as an SVHC if it meets one or more of the following criteria: The "equivalent concern" criterion is significant because it is this classification which allows substances which are, for example, neurotoxic, endocrine-disrupting or otherwise present an unanticipated environmental health risk to be regulated under REACH.

Many such substances are already subject to restrictions on their use within the European Union, such as those in Annex XVII of the REACH Regulation.

On the basis of this technical report, the Agency decides whether to prioritise the substance, in effect, whether to make a recommendation to the European Commission to add the substance to Annex XIV of the REACH Regulation, making its use subject to authorisation.

Suppliers of pure SVHCs must provide their customers with a safety data sheet (SDS).

[14] Suppliers of mixtures of substances which contain more than 0.1% by weight of any SVHC must provide their customers with a safety data sheet on request.
