Economic Operators Under EU MDR: Who Does What
Every medical device that reaches a clinic or institutional buyer in the EU has passed through a chain of economic operators, a term the Medical Device Regulation (MDR, Regulation (EU) 2017/745) uses for the different parties who place, make available or otherwise facilitate access to a device on the market. The MDR does not treat this chain as a single undifferentiated supply line. It assigns each role a distinct set of legal obligations, and knowing where one role's duty ends and the next one's begins is central to how a distributor manages risk.
Four Roles, One Shared Objective
The MDR recognizes four principal economic-operator roles: the manufacturer, the authorized representative, the importer and the distributor. A single company can hold more than one role depending on what it does with a device (a distributor that relabels or repackages a product under its own name can take on manufacturer-level obligations for that activity). The shared objective is the same across all four: making sure a device that reaches the end user still meets the requirements under which it was certified, with a traceable party responsible if something goes wrong.
| Role | Core relationship to the device | Primary obligation focus | |---|---|---| | Manufacturer | Designs or has designed the device; places it on the market under its own name | Conformity, technical documentation, clinical evidence | | Authorized representative | EU-based party appointed by a non-EU manufacturer | Legal point of contact for the manufacturer within the EU | | Importer | First EU-based party to place a non-EU manufacturer's device on the market | Verifies the device and its documentation before distribution | | Distributor | Makes a device available in the supply chain after the importer | Verifies packaging, labeling, storage and transport conditions |
The Manufacturer: Where Responsibility Originates
The manufacturer carries the broadest set of duties, since it determines the device's design, intended purpose and risk classification. This includes compiling technical documentation, maintaining a quality management system, conducting the conformity assessment appropriate to the device's class, and issuing the declaration of conformity behind the CE mark. Larger or higher-risk manufacturers must also designate a person responsible for regulatory compliance (PRRC), an internal role with specific accountability for regulatory matters.
The Authorized Representative: An EU Foothold for Non-EU Manufacturers
A manufacturer based outside the EU cannot place devices on the EU market without appointing an authorized representative established within the Union. This representative does not design or manufacture the device, but acts as the manufacturer's legal contact for EU authorities, holds certain documentation available for inspection, and can share liability in some circumstances if the manufacturer's own obligations are not met. For a distributor, confirming the identity of a valid authorized representative is one of the first checks worth making when sourcing from a non-EU manufacturer.
Importers and Distributors: Verification All the Way to the Point of Sale
An importer is the first EU-based party in the chain for a device made outside the Union. Before placing a device on the market, MDR principles hold that the importer should verify that the device bears the required CE marking, that a declaration of conformity exists, that an authorized representative has been appointed where required, and that labeling and instructions are in the appropriate language. A distributor, meaning any later party that makes the device available, is expected to carry out an equivalent check further down the chain: confirming that CE marking, labeling and, where applicable, Unique Device Identification (UDI) are present, and that storage and transport have not compromised the device. Both roles are verification roles, not design or testing roles; neither is re-certifying the device itself. If either party identifies a non-conformity, MDR principles hold that the device should not be made available until it is corrected, and that the manufacturer and, where appropriate, the competent authority should be informed.
Why This Framework Matters to Buyers
For an institutional buyer or clinic, this chain is a practical due-diligence tool, not an abstract regulatory detail. Knowing which party was supposed to have verified what makes it possible to ask precise questions: who is the authorized representative for this manufacturer, does the importer's name appear on the packaging, has the distributor documented its own incoming checks. These questions, and the quality agreements that often formalize the answers between manufacturers and distributors, are what turn a regulatory framework into an operational safeguard.
The Takeaway
The MDR's economic-operator structure exists so that responsibility for a device's conformity never becomes diffuse as it moves through the supply chain. Each role, manufacturer, authorized representative, importer and distributor, has a defined and verifiable set of duties, and a buyer who understands that structure is better equipped to evaluate the integrity of the chain a product has traveled through before it reaches them.
