MDR and EUDAMED:

A new milestone for medical device traceability

MDR and EUDAMED: what this really means for stakeholders in the medical supply chain

On May 28, 2026, EUDAMED’s UDI/Devices module enters its operational phase. For those who work daily with medical device manufacturers, this is a significant milestone.

Traceability: the new standard for industrial control

Behind the acronym UDI (Unique Device Identification), the requirement is clear: every element of the value chain—from the metal ingot to the implanted device—must be documented, consistent, and accessible at any time.

For manufacturers, this means their suppliers must be able to provide reliable data, not just compliant materials.

Metal raw material suppliers are not registered in EUDAMED, but they directly influence their customers’ ability to achieve and maintain proper compliance within the system.

What our OEM customers and their subcontractors expect from us, and what we deliver

The same questions arise regularly:

“Can you guarantee full batch traceability?”
“Are your material certificates available immediately?”
“How do you manage changes in alloy grade or supplier?”

These are not new questions. The MDR did not create them; it simply provided a formal framework. What it changed is their nature: what was once considered best practice has become auditable. Good documentation is no longer merely a sign of professionalism, it is a verifiable requirement.

At STAINLESS Group, we have been meeting these expectations for many years through our in-house metallurgical testing laboratory, structured batch-by-batch traceability, long-term partnerships with alloy producers, readily available documentation, and responsiveness. The medical sector leaves no room for approximation, and this is a reality we embrace even before our customers express it.

A long-term trend, not a temporary constraint

The strengthening of MDR and EUDAMED requirements confirms a deeper industry trend. The distinction between product quality and documentation quality is gradually disappearing. Manufacturers need partners who can master both.

The implementation of the UDI/Devices module in May 2026 further reinforces a key MDR principle: traceability is becoming fully integrated, digital, and structured at a European level.

A supplier’s reliability is no longer measured solely by the compliance of its materials. It is also measured by its ability to provide usable data at the right time and in the right format.

In response to these requirements, MDR audit readiness, responsiveness in supplying data, and the ability to support manufacturers in meeting compliance obligations are becoming critical factors in securing the medical device supply chain.
