Q: Where should I place the UDI on my product?

A: The UDI should be displayed on the device label and all upper-level packaging where it can be seen by users. For certain cases, the UDI can be placed on the next higher packaging if individually packed class I and IIa single-use devices.

Q: What are the implementation dates for UDI requirements?

A: The implementation dates for UDI requirements depend on the risk class of the medical device: Class III and implantable devices should have implemented UDI by 26th May 2021, Class IIa and IIb by 26th May 2023, and Class I by 26th May 2025.

Q: What is the UDI format for combination products?
