Our Core Business Values

Similar to other international organizations, the Preparatory Commission for the CTBTO follows the procurement principles of fairness, integrity, transparency, effective competition and best value for money, as well as international best practices.

This is reflected throughout the procurement process which is laid down in our procurement framework.

Suppliers that wish to work with us or already conduct business with the Preparatory Commission for the CTBTO are required to adhere to the UN Supplier Code of Conduct and any other ethical requirements as outlined in our tenders and/or contractual documents – please see the General Conditions of Contract.​ ​
