IUCLID
In the EU, the IUCLID software is required for registering substances (Article 111 REACH) and in Switzerland for notifying new substances. This program and all associated documents and supplementary databases can be downloaded free of charge from the following address: IUCLID
Submit IUCLID6 export files (but not the write-protected dossier files, see Annex III of the guidelines) using the E-application for chemicals (RPC): https://www.rpc.admin.ch/rpc/private/
Submit additional or supplementary test report summaries as an export file (allows the relevant endpoints to be imported).
In the event of problems with IUCLID, support is available from the REACH helpdesk.
