UK Declaration of Conformity

After Britain leaving the EU, there have been many changes in the regulations regarding medical devices. An example of this is the UK’s Declaration of Conformity.

UK Declaration of Conformity (DoC) is a technical document that products with UKCA marking should possess. The information needed on the Declaration of Conformity (DoC) is largely the same as what was required on an EU Declaration of Conformity.

According to UK’s guidance on UKCA marking, manufacturers are recommended to keep a separate UK DoC even if their product already has an EU DoC. Moreover, this document should be available to authorities on request.
