Understanding SVHCs and the REACH Authorisation Process

One of the aims of REACH is the identification and control of substances which pose a high risk to human health or the environment. This process begins when there is sufficient scientific evidence to suggest that a substance poses a significant concern. This evidence is used as a justification for greater control to ECHA by EU Member State Competent Authorities, who nominate substances about which they have particular concerns.

If, after a review of the evidence, the wider EU membership and the EU Commission accept the need for the use of a substance to be controlled, the substance is formally recognised as a "Substance of Very High Concern" (SVHC). The names of substances that have been determined to be SVHCs are published by the European Chemicals Agency (ECHA) in the form of ‘the candidate list’. This list represents those substances which may be subject to Authorisation in the future.


Currently there are 151 substances on the REACH candidate list but this will increase over time (see ‘How and when will the Candidate List be updated?’).


REACH Regulation requires companies to let their customers know if SVHCs are contained within their products. As a consequence, all manufacturers, retailers, distributers/importers and suppliers of components or parts must identify if their products contain SVHCs and determine whether or not these substances are subject to Authorisation and what action is required to ensure their supply chain is compliant with REACH.

We offer services to help companies determine if their products contain SVHCs and assess the impact on their business and supply chains.
