Existing supplier registrations will be updated to reflect the changes made. A general notification will be issued on this web-site when the process has been completed and all changes have been incorporated accordingly. Potential suppliers will continue to be responsible for ensuring that they are registered for the categories of equipment and/or services of their choosing.

Vendors and companies wishing to register with ICAO's Tendering website may do so on this website by clicking on "Register" under "New Users" on the left. Any concerns regarding the registration process should be routed to the following e-mail address specifying "Queries with Registration".

In order to ensure a fair, competitive and open process, once a project or procurement is published on the ICAO Tendering Website all communications from interested vendors or persons acting on their behalf, relevant to a published tender, must be directed to ICAO via this website as indicated in the tender document Instructions to Tenderers.

Vendors or respondents to any tender or solicitation published by ICAO, or persons acting on their behalf shall not contact (via e-mail or telephone) any employee of the ICAO Procurement Section concerning any aspect of this solicitation between the publishing of the solicitation/tender and the date of the notice of award. Violation of this provision may be grounds for rejecting a response.

A tender price and document must be fully uploaded and submitted in the ICAO Tendering System by the indicated closing date/time. It is recommended that potential suppliers wishing to upload their proposal do so within sufficient allotted time and before the closing date of the tender. ICAO is not responsible for issues that may arise when uploading and submitting documents such as speed, time of upload, format, type or quality of documents. Please note that all bids/proposals received after the closing period WILL NOT be accepted by the system under any circumstances. Note also that pricing or financial information provided directly to any ICAO recipient other than through the ICAO tendering portal, will automatically disqualify the potential bidder for the tender, as such action compromises the integrity of the Tender process. Please refer to the Instructions to Tenders for details.

In accordance with standard UN Procurement Guidelines, vendors which have been unsuccessful in a tendering exercise and wish to obtain a de-brief on the tender/solicitation outcome, may do so by contacting ICAO at A debrief meeting will be arranged where the following framework shall apply: During the debriefing only the proposal from the unsuccessful supplier will be reviewed. ICAO will discuss the sections / points of this proposal which were considered not acceptable or non compliant or where ICAO envisages there could be some improvements. ICAO will clarify the evaluation criteria used, the reasons for non-compliance and indicate areas of improvement in future tender participation. In no circumstances will ICAO discuss or disclose any technical details about the proposal selected for award of the contract other than the published final price of the selected vendor.

At any time, suppliers must refrain from directly contacting by telephone or personal work emails, any ICAO Procurement Staff member regarding potential/pipeline projects, and budgets.

Vendors or companies requesting a meeting to demonstrate or provide briefings on their goods/services and/or to obtain information on ICAO Procurement opportunities may do so by contacting ICAO at, explaining the intent. If deemed appropriate, the procurement section shall contact the vendor in writing and propose a date for a meeting, if deemed appropriate, which a minimum of two ICAO Procurement Staff shall attend.
