EMDN Classification for Medical Devices
Every device registered in EUDAMED must carry a valid EMDN code, the European Medical Device Nomenclature. With 8,454 codes across an 11-category hierarchy, finding the right one is the step most manufacturers get wrong.
What is EMDN?
The European Medical Device Nomenclature (EMDN) is a hierarchical classification system developed by the European Commission specifically for EUDAMED registration. It replaces the use of GMDN codes in the EU context and is the mandatory nomenclature for all device registrations under MDR (2017/745) and IVDR (2017/746).
EMDN codes follow a structured alphanumeric format. The first character is a letter identifying the top-level category. Subsequent characters narrow the classification down through subcategories to the most specific applicable code, typically 5 to 9 characters total. For example: P090101 identifies a single-use soft contact lens specifically designed for daily wear.
The EMDN taxonomy is published and maintained by the European Commission. It is versioned, updated periodically, and freely accessible through the EUDAMED public interface and the official EC nomenclature browser.
The 11 top-level EMDN categories
Each category branches into subcategories, device types, and specific device codes.
How to find the right EMDN code
Classification is a top-down process starting from intended purpose, not physical design.
Define the primary intended purpose
EMDN is purpose-driven. A device used for multiple functions takes the code for its primary intended purpose. Write this down in one sentence before opening the nomenclature browser.
Select the top-level category
Choose the letter category that matches the intended purpose. Use the 11-category list above. If your device spans two categories, the primary intended purpose determines the letter.
Navigate down the hierarchy
From the category level, step through subcategories using the EUDAMED nomenclature browser or the EC's EMDN browser tool. At each level, read all available options before selecting; sibling codes often look similar.
Verify at the leaf node
The correct code is always the most specific applicable one: the leaf node with no further subcategories. If you stop at a parent code, EUDAMED will reject the submission.
Cross-check with similar registered devices
Search EUDAMED's public device registry for similar products already registered. The EMDN codes other manufacturers used for comparable devices provide a useful sanity check.
Note for IVD manufacturers
In vitro diagnostic devices fall under the K category in EMDN. However, IVDs also have a separate IVDR classification (Class A, B, C, D) based on risk. The EMDN code and the IVDR risk class are both required in EUDAMED and must be consistent with each other. Mismatches between the EMDN code and the declared risk class are a common cause of EUDAMED submission failure for IVD manufacturers.
Common EMDN classification mistakes
These errors account for the majority of EUDAMED submission rejections related to nomenclature.
Using a parent category instead of a leaf code
EMDN is hierarchical: codes go 3-5 levels deep. EUDAMED requires the most specific code available. Submitting 'P' (Ophthalmic) instead of 'P090101' (Single-use contact lens) will fail validation.
Confusing GMDN with EMDN
GMDN (Global Medical Device Nomenclature) and EMDN are separate systems with different code structures. A GMDN code cannot be used in the EMDN field in EUDAMED. They require separate classification work.
One device, one EMDN code
A single device registration takes exactly one EMDN code. If your device spans multiple categories, you must choose the primary intended purpose. Multi-coding is not permitted.
Skipping the intended purpose check
Two physically identical devices can have different EMDN codes if their intended purposes differ. Classification is function-first, not design-first. Always start with intended purpose.
Using outdated EMDN versions
The EMDN taxonomy is versioned and updated periodically. Codes present in an older version may be deprecated or reorganised. Always classify against the current published version.
How EUDAMate handles EMDN classification
EUDAMate includes an AI-assisted EMDN classification engine trained on the full 8,454-code taxonomy. When you upload your device data, the engine reads the device description and intended purpose and suggests the most specific applicable EMDN code, along with a confidence score and alternative candidates.
