Creating your registration dossier

After you have compiled all the information on your substance necessary for fulfilling the REACH requirements, you need to document your findings in a registration dossier.

The file that you submit to ECHA to register your substance is called a dossier. A dossier is a read-only copy of your substance dataset, complemented with information about the type of your registration.

Two types of dossiers can be prepared depending on your role in the joint submission:

  1. The lead registrant dossier, which includes the identity of the substance covered in the joint submission, the information on the properties of the substance as well as the company-specific information of the lead registrant.

  2. Member dossiers, where all the other registrants include their company-specific information, like contact details, exact substance identification, the volumes produced or imported and the uses of the chemical by their customers.

For both types of dossiers dossier you can use:

  1. IUCLID Cloud 
    If you are a consultant working for a registrant or if you are a registrant yourself with non-frequent use of IUCLID or have only a few substances to manage.
  2. IUCLID application
    If you manage large amounts of data.
