REACH is based on the principle of one substance, one registration. For this reason, when a manufacturer and/or importer pre-registers a substance, he becomes a participant in a SIEF (Substance Information Exchange Forum).
The SIEF includes all companies that have pre-registered one and the same substance. The SIEF facilitates data sharing between Pre-Registrants, and ultimately, where possible, the joint submission of the technical dossier. The aim is to avoid unnecessary testing, or repetition of tests on vertebrate animals, and to ease the financial burden on registrants.
REACH does not, however, provide for clear rules on how information should be exchanged between the SIEF participants.
In anticipation of these tasks, many companies have decided to combine their resources to set up consortia which provide a formal forum for organising all activities related to the preparation of the REACH registration dossiers.
