Illustration showing the role of an EU Authorised Representative under the EU MDR and IVDR, depicting a non-EU manufacturer, the Authorised Representative, Article 11 compliance documentation, EUDAMED registration, Competent Authority communication and medical device regulatory oversight within the European Union.

EU Authorised Representative

Manufacturers based outside the European Union must appoint an EU Authorised Representative (EU AR or EC REP) before placing medical devices or in vitro diagnostic medical devices on the European market under the Medical Device Regulation (EU) 2017/745 (MDR) and In Vitro Diagnostic Medical Device Regulation (EU) 2017/746 (IVDR). Acting as the manufacturer’s legal representative within the EU, the Authorised Representative performs important regulatory duties, supports communication with Competent Authorities and shares legal responsibility for compliance. This guide explains who needs an EU Authorised Representative, their legal obligations under Article 11, and how to choose the right partner.

UK Responsible Person (UKRP) – Medical Devices

The UKRP must provide written evidence that they have the manufacturer’s authority to act as their UK Responsible Person. Importers and distributors are not required to appoint a UK Responsible Person.

The UKRP acts on behalf of the non-UK manufacturer to carry out specified tasks in relation to the manufacturer’s obligations. As noted above, this includes registering the manufacturer’s devices with the MHRA before the devices can be placed on the UK market.

Skin Irritation Testing in the biological evaluation of medical devices (ISO 10993-23)

ISO 10993-23 Skin Irritation Testing Explained: Methods, Requirements and Regulatory Expectations

Skin irritation occurs when a substance causes inflammation or damage to the skin upon contact. For medical devices, this can be a serious concern, as they are often in prolonged contact with the skin. The consequences of not adequately testing for irritation can range from minor redness to severe dermatitis, leading to discomfort, injury, or even infection in users. Therefore, reliable testing methods are crucial to ensure that products are safe before they reach the market.
