CE Marking Medical Devices

Blog, EU Regulations, Guides and Advice, Standards, UK Regulations / David Small

The CE marking of medical devices and in vitro diagnostic devices (IVDs) is a requirement of EU regulations (EU 2017/745 for medical devices and EU 2017/746 for IVDs) to lawfully place medical devices on the EU market. Manufacturers must affix the CE mark on the medical device or IVD itself and on the primary packaging (or just on the packaging if affixing to the device itself it not possible). The CE mark should also be placed on any instructions for use and any labelling. The use of the CE mark identifies that a medical device or IVD conforms to EU regulatory requirements and is a symbol that a device meets safety standards.
