  • Request for information or RFI - Used as a vehicle to request market information, to inform of the results of the events of the procurement process, to receive questions related to de Bid guidelines and to obtain any clarifications requested by Pemex.

  • Request for Proposal or RFP - Used as a vehicle for the submission of legal, economic and technical proposals.


These events are setup with the conditions of the event, such as the start and end of date and time, accordance with the planned schedule.

Once you are visible to Pemex buyers, you may receive an email with the link to access different business opportunities in the system through this kind of events.
