The Mexican government purchases a large variety of services, raw materials, spare parts and finished goods from the private sector every year. Procurement is generally carried out via open tendering through public notices, but it is highly advisable to work with a Mexican partner if you intend to bid on a tender. This will make it much easier to participate in the bidding process and also (if you secure the contract) to provide after-sales support. Information on open tenders (in Spanish) is available on the Sistema Electronico de Compras Gubernamentales ( CompraNet) website.
