Vendor Registration

To be considered for registration, it is important that potential vendors/organizations provide correct and accurate information.

How to register as a potential supplier of goods and/or services to UNESCAP

Companies that wish to be considered for participating in UNESCAP tendering exercises must register on the United Nations Global Marketplace (UNGM).

By registering on UNGM, vendors become part of a database from which the UN searches for suppliers and can access UNESCAP Expression of Interest Documents online. Furthermore, by subscribing to the Tender Alert Service, companies can be automatically notified via e-mail of all UN business opportunities that match the products and services for which they have registered.

Please note that the UNGM provides for three levels of registration, as follows:
BASIC REGISTRATION: For business opportunities with a value up to US $40,000
LEVEL 1: For business opportunities with a value between US $40,000 and US $500,000
LEVEL 2: For business opportunities with a value above US $500,000

If you require assistance or technical help in completing the registration requirements, please forward your inquiry to the Procurement Unit at this email address:


  • How can I register as a supplier to ESCAP?

    Companies that wish to be considered for participating in UNESCAP tendering exercises must register on the United Nations Global Marketplace (UNGM).
  • I have been approved as a vendor but I have never been invited to bid.

    This may be because the product or service you offer is rarely required, and we simply haven't needed to buy any.
  • I heard there is a bid going on for "xyz" product or service. I want to participate. Who shall I contact?

    You are encouraged to contact our offices. Please note that you will be required to undertake the same registration process before your company would be considered.
  • Are ESCAP purchases tax/duty free?

    As an inter-governmental organization, ESCAP is exempt from payment of al taxes and duties for all its purchases.
  • Does ESCAP conduct purchases for the whole United Nations system?

    No. ESCAP organizes procurement for the ESCAP Secretariat, and associated programmes/projects only. Other UN agencies, funds, and programmes carry out their own procurement activities within their own established rules.
  • How does the ESCAP pay suppliers?

    ESCAP standard payment terms are net payable in 30 days upon receipt of invoice and delivery of goods or performance of contractual services, whichever is later. ESCAP do not issue letters of credit or make an advance payment.
  • Does the United Nations require performance guarantee?

    ESCAP may require a successful contractor to furnish performance bonds in the United Nations standard format or similar forms of guarantee. The amount of performance bonds/guarantees will vary depending on the nature of the requirements. The United Nations may also include a liquidated damages clause in its contractual documents in case adherence to the schedule of delivery of goods or performance of contractual services is critical to meet the requirements of ESCAP.
