There are three main procedures for obtaining marketing authorization in the EU: 1. Centralized Procedure allows applicants to obtain approval in all EU countries by applying to the EMEA and results in a binding Commission decision. It is mandatory for certain product types. 2. Mutual Recognition Procedure involves approval in multiple countries based on recognition of an existing national authorization. Applications are made to both a Reference and Concerned Member States. 3. Decentralized Procedure is similar but applies to products without prior EU authorization. Applications are made simultaneously to a Reference and Concerned Member States.
