An organisation serving heritage
OIMAP is an intergovernmental organisation created by treaty in 2007. It brings together the States that want an art market that is transparent, safe and respectful of communities of origin. Its motto comes down to three verbs: observe, regulate, protect.
It addresses States, market professionals, museums, collectors and the general public. Discover its mandate and its presentation.
Six concrete missions
Observing the market through reliable data; regulating through common standards, including the seven OIMAP Directives of 2019; protecting heritage through the BIOP database; certifying works; training professionals; arbitrating disputes.
Each mission is presented on the page The six missions and detailed in a section of the site: market, regulation, protection, certification, training and arbitration.
Online services
The OIMAP Desk brings together the procedures: registration of a work, certificates of authenticity and provenance, import-export licence, sale accreditation, digital certification. Each case receives a number in the form OIMAP-AAAA-NNNNNN, which allows it to be tracked.
To check a certificate you have received, the page Verify a document allows verification by number or QR code. The procedures are presented in the OIMAP Desk.
Everyday protection
A theft or loss can be reported free of charge: the alert is processed within 24 hours and circulated to customs, police forces and accredited auction houses. A free subscription allows you to receive alerts by e-mail.
Before buying, consult the BIOP alerts and apply the ten good practices of the Collector's Charter.
Staying informed
The news, the calendar and the press releases follow the life of the Organisation. The 19th General Assembly takes place in Singapore on 10–12 June 2026.
A free newsletter summarises the essentials each month.
