Only registered substances are allowed to be manufactured or imported.

Each manufacturer or importer of a substance shall submit his registration dossier for the substance to the Agency, accompanied by a fee.

The registration dossiers submitted to the Agency will be handled electronically to facilitate the management of the expected amount of registrations that will be submitted. The Agency assigns a registration number and a registration date to each registration dossier received and immediately communicates this information to the registrant.

Within 3 weeks of the registration date, the Agency performs an automated completeness check of the dossier to ascertain that all elements required for the registration are included. If the registration is incomplete, the Agency will inform the registrant within these 3 weeks from the registration date about which further information is needed and will set a deadline for completion of the dossier.

The registrant needs to submit the requested missing information in an updated dossier to the Agency within the set deadline. The Agency then confirms the submission date of this information and makes a further completeness check within 3 weeks of receipt of the updated dossier.

If the registrant fails to complete his registration within the set deadline, the registration will be rejected by the Agency and the manufacturer or importer is not allowed to start or continue manufacture or import of the substance.

The Agency will forward the registration dossier, the registration number and date, and the result of the completeness check to the authorities of the Member States in which the manufacturers and importers are established to enable enforcement action, if necessary. Also the further information that is submitted for completion of the dossier will be forwarded to the competent authority together with the result of the second completeness check.
