5. How do I notify via IUCLID 5?

Notification via IUCLID 5 is the most effective solution in the following cases:

• You have created IUCLID 5 dossiers for substances to be notified: IUCLID 5 is your product dossier management tool, and you have started work on compiling REACh registration dossiers for the second or third phases (June 2013, June 2018).

• You want to keep the IUPAC name of your substance confidential: you're developing new chemical structures whose names must not be published.

• You wish to notify a substance with several composition profiles or/and several classifications/labels: you need to notify a UVCB substance, a substance resulting from different industrial processes leading to different impurity profiles.
