You should use this webform if you want to request a change to the chemical identifiers of a registered substance.
The information you submit with this request is assessed by ECHA. If the Agency considers that the service can be provided, it will issue a service charge to each affected registrant.
Please fill in the following fields. Compulsory fields are marked with an asterisk (*). Please also attach a "Joint Submission Plan" (JSP) and documentary evidence that all the co-registrants agree with the
adaptations specified in the JSP (if applicable) and that they commit to update their dossier within 2 months after ECHA carries out the technical changes in REACH-IT. You can download a JSP template (Microsoft Excel document) from this link.
The template can be used for both joint submissions and individual submissions. Please read carefully the instructions included. When done, click the Submit to ECHA button below.
If you would like to submit more than one document, please create a zip archive where you include all files and upload the zip file as attachment. Maximum file size is 10 MB.
If you have received a communication letter from ECHA asking you to submit the request, it is sufficient to provide the ECHA communication number instead of a justification.
