Comply with UK REACH: submit and manage chemical registrations and notifications
Use this service to submit and manage chemical registrations and notifications.
If you’re based in Great Britain (England, Scotland and Wales) use this service to:
- submit a new registration for a substance
- 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
Before you start
You’ll need a Government Gateway account and a Defra account to sign into this service.
If you don’t have a Government Gateway account, you can set one up when you use this service for the first time.
You must log in to your Government Gateway account at least once every 3 years. If you don’t, you’ll lose access to your account and its data.
Follow guidance on how to create a Government Gateway account and a Defra account to access the Comply with UK REACH service.
Make sure your substance information is in the correct format as i6z dossier files. You can use IUCLID 6 (or later) to create the files.
Read the UK REACH guidance on the Health and Safety Executive (HSE) website.
