Downstream use notifications of authorised uses

Applications for authorisation can cover uses of a given substance by the applicant, uses further down in the supply chain, or both.

Downstream users covered by an authorisation granted to an actor up their supply chain must notify ECHA of their use. This requirement is based on Article 66 of REACH.

ECHA keeps a register of downstream user notifications and passes the information to the Member State competent authorities.

The graph below gives an overview of all downstream user notifications received to date. For completeness, for the respective substances also the granted authorisations are presented. ECHA will update the information on a quarterly basis.

More details on the geographical distribution of uses are available under ‘Maps and graphs’.

Information collected from individual notifications is presented under ‘Register of notifications’.

The information provided is based on notifications received from users. Therefore, inaccuracies may exist. Please consult ECHA’s legal notice for further information.


Authorisations to use SVHCs can be granted if an applicant can demonstrate that the risk from the use of the substance is adequately controlled, or that the socio-economic benefits outweigh the risks and there are no suitable alternatives. All authorisations are subject to a time-limited review period. The authorisation process aims to ensure that SVHCs are progressively replaced by less dangerous substances or technologies where technically and economically feasible alternatives are available. For more information about the authorisation process, follow the links available on this page.

For more information regarding the public version of the notification register and its aims, see ‘Information from downstream user notifications made public by ECHA’.
