The registrant of a substance needs to compile all the required information in a registration dossier, which consists of two main components:
A technical dossier, always required for all substances subject to the registration obligations
A chemical safety report, required if the registrant manufactures or imports a substance in quantities of ten tonnes or more per year.
The registration dossier has to be prepared using the IUCLID 5 software application. IUCLID 5 implements the Harmonised Templates developed by the OECD and it is compatible with other chemical legislations around the world.
Once the dossier has been created with IUCLID 5, it has to be submitted to ECHA through REACH-IT.
Manufacturers and importers have to collect all existing available information on the intrinsic properties of a substance as well as on its manufacture, uses and exposure.
