How do I update my notifications?
Placing a chemical substance on the market, notifying the classification to the European Chemicals Agency (ECHA)

Elements may lead to a change in the classification of your substance: new knowledge on intrinsic properties, evolution of classification criteria... In this case, you need to modify the content of your notification.

The update process is identical to that for creating a notification. All three tools described above can be used. The additional information required is :

• notification number ;

• the EC number of the substance or the list number assigned following notification;

• submission number (only via IUCLID 5) ;

• justification for the update.
