Which D03 codes can be used in a EUDAMED device record?

11 of the 14 codes listed under D03 (Chlorine Derivatives for the Disinfection of Medical Devices) are terminal and can be selected. The other 3 are branch headings that cannot.

How many D03 codes are catch-all entries?

4 terminal codes under D03 are "- Other" entries, 36% of the branch. The remaining 7 name a specific device type.

EMDN D03: Chlorine Derivatives for the Disinfection of Medical Devices

Complete hierarchy for EMDN group D03 in category D (Disinfectants, Antiseptics, Sterilising Agents and Detergents for Medical Devices): 11 terminal codes, EMDN v2026. Terminal codes are the ones accepted in a EUDAMED device record.

Registered classes, as of 8 Sep 2026. For each code with at least 20 registrations under a legislation, the chip shows how devices registered in EUDAMED under that code are classed, counted once per primary UDI-DI and kept separate for each legislation. It is not a determination. The class of a device comes from the MDR and IVDR classification rules for its intended purpose. MDD and IVDD classes are the directive classification and can differ from the class the same device would have under MDR or IVDR.

fallback entries: Other and Accessories

The Chlorine Derivatives for the Disinfection of Medical Devices branch runs 3 levels deep. 3 entries below are branch headings that group other codes rather than naming a device, so a classification has to resolve all the way down to one of the 11 codes marked terminal.

4 terminal codes are “- Other” entries, 36% of the branch. An “- Other” code is the residual slot for devices its siblings do not name, so it is worth ruling out every specific sibling before settling on one.

The largest sub-branch is D0301 (Hypochlorites and Associates for the Disinfection of Medical Devices), holding 6 of the 11 terminal codes.
