CIMAC's organisational structure is based on the CIMAC Council, the CIMAC Board, and the CIMAC Working Groups.

The CIMAC Council, which formulates CIMAC's policy, takes policy decisions and controls implementation, consists of the National Member Associations, each having two seats in the Council, and the Corporate Members, each having one seat per country in the Council.

The CIMAC Executive Board has clearly defined responsibilities and implements CIMAC's policy. Its members are responsible for the day to day business of CIMAC. They are elected by the CIMAC Council for a tenure of three years, as usual for a period between one and another CIMAC Congress.
