The pre-registration period, between 1 June and 1 December 2008, allowed potential registrants of the same phase-in substance to get together and submit a registration dossier jointly. Pre-registration was a requisite to benefit from the extended registration deadlines foreseen for these substances.
Potential registrants who, for the first time after 1 December 2008, manufacture or import a phase-in substance in quantities of one tonne per year or more can still submit certain information to ECHA (late pre-registration) and benefit from the extended deadlines. Producers and importers of articles with an intended release of a substance can also submit a late pre-registration.
Late pre-registrations have to be submitted within six months after the manufacturing or importing of the substance that exceeds the one-tonne threshold and no later than twelve months before the relevant registration deadline. Therefore, the late pre-registration period ends on 31 May 2012 for substances to be registered by 31 May 2013, and 31 May 2017 for substances to be registered by 31 May 2018.
Late pre-registration is only obligatory if companies want to benefit from the extended registration deadlines. Companies can also decide to register their phase-in substances immediately, but in this case it is necessary to first submit an inquiry.
After pre-registration and subsequent discussions on the sameness of the substance, the company becomes a member of a Substance Information Exchange Forum (SIEF).
