The substance identity adaptation webform has been modified to remind co-registrants of their obligation to keep their dossiers up to date when submitting their joint submission plan and documentary evidence.

The service was launched in 2014 to enable registrants to change the chemical identifiers, e.g.  EC number in their REACH dossiers, if the substance has been incorrectly identified.

More information on how to change your substance identifier are available in a dedicated webpage on ECHAS website.
