Full CIPAC members are official analytical chemists who are elected because of their expertise in the field of pesticide formulation analysis and their contributions to the achievements of the CIPAC goals.

Only one full member is appointed per country. Other people may be elected as correspondents or observers, depending on their contributions to the CIPAC work.

Liaison with other international organisations is maintained through the appointment of representatives with correspondent status.

Industry participates through their experts who report on special subjects and conduct collaborative studies, or take part in the trials.
