About the EU QP system

The EU GMP first adopted the QP system in 1975. In the near 50 years that followed,it was proven to be an advanced system for pharmaceutical quality management and has thus become a core element of the EU GMP.

The EU has strict requirements for QPs and has clearly defined the legal status,required qualifications and responsibilities of QPs in the European Council Directive (2001/83/EC) and the EU GMP Annex 16 on the Certification by a Qualified Person and Batch Release. These high requirements make QPs some of the most authoritative experts in pharmaceutical manufacturing.
