The EDQM maintains a database that contains the relevant information about the issued Certificates of Suitability (CEP). The publicly available version allows you to search for a variety of information:
Due to user requests, the database now allows users to search for CEPs which have an expiration/end date. This information about the date is now listed for all CEPs (also for CEPs which are withdrawn or expired).
Here you can open the CEP database.
