Duty to inquire
Potential registrants of non-phase-in substances or phase-in substances that were not pre-registered have to inquire from ECHA whether a registration has previously been submitted for the same substance. In addition, they have to inform ECHA of their information needs so that the available data can be shared among the registrants of the same substance. ECHA assess the inquiry and then facilitates contact between the potential registrant and the previous registrants in order to enable data sharing. Potential registrants must wait for the result of the inquiry before submitting the registration dossiers or starting any tests on vertebrate animals. The inquiry dossier must include enough information to allow the correct identification of the substance so that ECHA can determine whether the same substance has previously been registered or whether there are other inquirers for the same substance, and so potential registrants are advised to pay particular attention to the substance identity information they provide.
Further information on the inquiry process is available in ECHA’s Q&As. There is further information on how to submit the inquiry dossier at http://www.echa.europa.eu/web/guest/support/dossier-submission-tools/reach-it/inquiry.
