Comply with UK REACH: submit and manage chemical registrations and notifications

Use the service to submit and manage chemical registrations and notifications.

If you’re based in Great Britain (England, Scotland and Wales) use this service to:

  • notify that you’re going to continue importing EU REACH registered substances by submitting a Downstream User Import Notification (DUIN)
  • transfer your assets, such as registrations, to another legal entity
  • submit your Northern Ireland notification
  • manage joint registrations - claim the lead registrant role, submit a lead dossier and approve joint registration group members
  • manage your Product and Process Orientated Research and Development (PPORD) notification
