(8 February 2019) With Brexit day fast approaching, ECHA published a preparedness note encouraging chemicals companies to take action prior to the UK’s withdrawal. In order to maintain market access, UK-based companies will have to transfer their business or appoint an only representative in an EU27/ EEA country. A “Brexit window” for the REACH IT system will be opened from the 12th to 29th of March to enable UK-based companies to change or transfer their registrations. EU27/ EEA downstream users relying on authorisations granted to UK-based companies will also need to make sure they can use another valid authorisation received by an EU27/ EEA-based company.
