UK-based standards body BSI warned devicemakers that their CE certificates in the UK could become invalid if the UK and EU fail to negotiate a Brexit deal by March 29.

BSI is advising manufacturers to migrate their existing CE certificates from its UK notified body to its Netherlands-based notified body before the deadline.

In an urgent notice to manufacturers, BSI said that when it initiated its contingency plan in August 2016, it “could not have foreseen the lack of political progress” toward a Brexit resolution.
