The private sector, a market player

Auction houses, galleries, insurers, carriers, laboratories and technology companies keep the art market alive. Their cooperation is valuable, provided it is properly regulated.
This page presents the forms of cooperation with the private sector and the rules that guarantee the Organisation's independence. Approved auction houses are presented in the Auction houses section.

Why cooperate with companies
Companies are the first to observe market developments and to handle works. Their data and tools are useful for improving traceability. In return, they benefit from a clear framework that secures transactions.
Cooperation covers specific topics: staff training, exchanges on fraud risks, deployment of verification tools, dissemination of good practices.



Auction houses
Approved auction houses undertake to verify the provenance of lots, to consult BIOP alerts before each sale and to keep documents for ten years (indicative). They are subject to inspections and may lose their approval in the event of a breach.
The procedure is presented in the Sale approval section, and the conformity label distinguishes the most rigorous establishments.
Laboratories and technical service providers
Laboratories carry out materials analyses, dating and imaging examinations. They collaborate with the Organisation under the list of partner laboratories, which specifies their areas of expertise.
Their reports are independent. OIMAP regularly checks the quality of their methods and may suspend a collaboration if anomalies are found.
Insurers, carriers and digital
Insurers and specialist carriers exchange with the Organisation on the risks of theft and damage, as well as on the insurance value stated in conservation reports. Digital companies contribute to the digital certification tools.
All remain subject to the Organisation's confidentiality rules. No personal data of clients is transmitted without a legal basis.
