The REACH Regulation requires companies registering the same substance to share data and to jointly submit their registration dossier.
For phase-in substances, all existing and potential registrants that have preregistered the same substance are part of a Substance Information Exchange Forum (SIEF) that aims to:
Facilitate the exchange of information on available data between co-registrant.
Agree on classification and labelling where there is a difference between co-registrants.
Main benefits of being part of a SIEF:
Increase knowledge on your substance.
Reduce costs of registration for everyone.
Avoid duplication of animal tests.
