Reference Agreements

​These are legal instruments through which Petróleos Mexicanos establishes the technical and commercial conditions under which, where applicable, suppliers may, through an award process, supply the procurement recipients with goods and/or services that can be standardized and contracted on a recurring basis.

They contribute to the better achievement of Pemex's goals and objectives by reducing the administrative burden on the operating areas in their procurement requirements, which are addressed in an expedited manner.

They are identified as ACREF.
