Enregistrement préalable
Enregistrement préalable
Pre-registration is only for companies planning to register phase-in (existing) substances. After pre-registration, potential registrants of the same substance can find each other's contact details in REACH-IT, so they can get in contact to agree on the sameness of their substance, form a substance information exchange forum (SIEF), share data and submit a registration dossier jointly.
- within six months after exceeding the one tonne per year threshold; and
- no later than 12 months before the relevant registration deadline.
Participating in a SIEF was a legal obligation for all registrants and pre-registrants of phase-in substances. The cooperation among co-registrants has to be maintained also after the deadline for data sharing and joint registration related matters.
In addition to potential registrants, also downstream users and any person or organisation holding data relevant to a phase-in substance could participate in the SIEF, if they had identified themselves as data holders and were willing to share their information.
SIEFs had no prescribed legal form and they were independently managed by industry. ECHA was not involved in their operations.
