Small enough to care and big enough to deliver

OR Service in the UK

On 31 January 2020 the United Kingdom (UK) withdrew from the European Union. Following this so-called Brexit, the new UK chemicals regulatory framework, UK REACH, came into force on 1 January 2021. It currently applies to Great Britain (GB).


Non-GB companies (manufacturers, formulators and suppliers) now have three options to ensure compliance with the new legal requirements, if they want to maintain access to the GB market:

  • use a GB subsidiary
  • appoint an Only Representative (OR) in the UK
  • the GB partner can assume the obligations as importer

Within 300 days of the end of the transition period (until 28 October 2021), GB-based importers and companies based outside GB, who have appointed an OR to act on their behalf, need to file a DUIN (downstream user import notification) under Article 127E of the statutory instrument (SI). This is to notify the HSE and to provide initial information regarding the substances they wish continue importing into GB.

Beginning after those 300 days, companies have 2, 4 or 6 years for the full registrations of their substances to be completed, depending on tonnage band and hazard profile. The Health and Safety Executive (HSE) acts as the UK Agency and has new IT tools available for data submission. Submitting an Article 26 inquiry to notify the HSE about the intention to register a substance is the first step.
