ECHA just published its latest tip of the week on what to do if your dossier is incomplete. After you submit your dossier to ECHA, they check that the information in it is complete before sending you your registration number. If some information is missing, ECHA will inform you through your REACH-IT account.

You can find more information, including practical advice, on the <link https: echa.europa.eu support registration working-together practical-advice-for-new-siefs _blank>ECHA website.
