The European Chemicals Agency (ECHA) is responsible for evaluating the dossiers submitted to it; this includes inquiry documents, Product and Process Orientated Research and Development documents (PPORD), and non-phase-in registration documents. The main reasons for rejection of a dossier include use of non-standardised methods of testing or incomplete or incorrectly completed documents.

Failure to include attachments or completing the necessary parts of the dossier will result in either an automated rejection (within hours of submission) or a rejection based on review by the ECHA within three weeks for non-phase-in substances or within three months for phase-in registrations.
