EU held registration: UK Downstream Users
UK Downstream Users
(who do not hold an EU REACH registration) importing chemicals from an EU/EEA country need to
ensure the substances they purchase are covered by a valid UK REACH registration. These UK
Downstream Users must notify the UK Agency HSE (Healthy and Safety Executive) using a
Downstream User Import Notification (DUIN) of their intention to continue importing
substances from the EU/EEA by 27 October 2021.
A new registration must then be submitted to the HSE within 2, 4 or 6 years of 28 October 2021,
depending on the registration tonnage band and hazard profile of the substance. Alternatively,
UK Downstream Users can encourage their EU/EEA supplier to appoint a GB-based Only Representative
(OR), or change their source to a GB registered supplier.
