Our mission
We help States, professionals and collectors share rules and tools so that trade in works and cultural property remains legal and traceable. Our mandate comprises six complementary missions.
We do not replace judges or national police forces. We provide them with data, standards and certification and mediation services.



Our values
Five values guide our work: integrity, scientific independence, cooperation, transparency and respect for communities of origin. They apply to our staff and our experts alike, through a common code of conduct.
Transparency means publishing our figures and procedures, and making it possible to verify online a document issued by the Organization.
Our members
The 67 Member States decide together in the General Assembly. The twenty-three founding States of 2007 have been joined by States from every continent, from the Pacific to West Africa.
Each member designates a focal point, applies the binding directives and pays an annual contribution. The membership procedures are described in the Member States section.
Our governance
The General Assembly sets the guidelines. The Executive Council, with fifteen members, prepares and monitors decisions. The Secretary-General heads the Secretariat, which implements and reports.
Five standing committees examine technical questions, from finance to cooperation and training. This organization is detailed in the organization chart.
