CompraNet Guide: Mexico Tender Search in English

What is CompraNet?

CompraNet is the Mexican federal government's electronic procurement platform — the mandatory portal for publishing and receiving bids on federal tenders for goods, services, leasing, and public works (obra pública). Historically hosted at compranet.hacienda.gob.mx, the platform has gone through a significant institutional transition.

Until 2022, CompraNet was administered by the Secretaría de la Función Pública (SFP). As part of broader federal reorganizations between 2022 and 2024 — which also consolidated energy procurement (CFE) and trimmed SFP's scope — the operation of CompraNet was transferred to the Secretaría de Hacienda y Crédito Público (SHCP). During this period the portal has migrated features, interfaces, and domain paths; vendors should verify the latest portal URL at gob.mx before filing bids.

What CompraNet publishes:

• Convocatorias — tender notices for licitación pública nacional and internacional
• Invitaciones a cuando menos tres personas — restricted invitations to pre-selected suppliers
• Adjudicaciones directas — direct awards above the publication threshold
• Programa Anual de Adquisiciones (PAAAS) — annual procurement plans from each federal entity
• Bases de licitación — downloadable specifications and bidding documents
• Fallos — award decisions with winning supplier, price, and scoring
• Contratos — the executed contract documents for transparency

Thresholds under LAASSP and LOPSRM

Mexico's federal procurement is governed by two core laws. LAASSP (Ley de Adquisiciones, Arrendamientos y Servicios del Sector Público) covers goods, services, and leasing. LOPSRM (Ley de Obras Públicas y Servicios Relacionados con las Mismas) covers public works and related services. Each law sets its own value thresholds, which are updated annually in the Presupuesto de Egresos de la Federación (PEF) — the federal budget decree.

The structure is the same across both laws: three procedure tiers based on estimated value. The MXN ranges below are indicative of recent PEF bands and vary by the size of the contracting entity's annual budget.

Licitación pública internacional is further split between "bajo la cobertura de tratados" (covered by free trade agreements) and "abierta" (open international). The former applies USMCA, CPTPP, and EU-Mexico FTA thresholds; the latter opens the tender to any country but may still require reciprocity. Always confirm current PEF threshold tables for the year in question — numeric bands above are illustrative.

Who buys on CompraNet?

Federal contracting authorities (dependencias y entidades) span ministries, decentralized agencies, productive state enterprises, and the armed forces. Several of the largest buyers move tens or hundreds of billions of pesos each year.

Note that CFE and Pemex operate under a special regime as empresas productivas del Estado — their procurement rules combine LAASSP/LOPSRM with sector-specific norms, and some contracts are published on their own portals in parallel with CompraNet.

How to register as a supplier

Becoming a Mexican federal supplier involves three layers: a tax identity, the RUPC registry, and often an entity-specific padrón. Skipping any of them can disqualify an otherwise competitive bid.

What you need:

• RFC — Registro Federal de Contribuyentes (Mexican tax ID). Foreign companies without Mexican presence can participate in licitaciones internacionales without an RFC but typically need one for contract execution and invoicing (CFDI)
• Opinión de Cumplimiento 32-D — positive tax compliance opinion from SAT (Mexico's tax authority), issued electronically and required for most federal awards
• RUPC — Registro Único de Proveedores y Contratistas, the unified supplier and contractor registry. Not mandatory for every bid but effectively required for repeat federal business
• Padrón de proveedores — many agencies (IMSS, CFE, Pemex) maintain their own supplier list with additional technical and financial requirements
• e.firma (FIEL) — SAT-issued digital certificate used to sign bids electronically on CompraNet
• Legal representation — foreign companies generally need a poder notarial (notarized power of attorney) for a Mexican legal representative

Foreign companies note: USMCA, CPTPP, and EU-Mexico FTA suppliers have preferential access to covered international procedures. However, bidding still requires Spanish-language documentation, apostilled and translated corporate records, and almost always a local legal or tax representative for contract execution.

Language glossary: core Spanish procurement terms

CompraNet is Spanish-only. Even the international tender notices are published in Spanish with — at best — an English annex. Learning the core vocabulary is essential for efficient search.

• Licitación pública — open public tender (nacional or internacional)
• Invitación a cuando menos tres personas — restricted invitation to at least three suppliers
• Adjudicación directa — direct award without competition
• Obra pública — public works / construction under LOPSRM
• Bases — the tender bidding documents (specifications, requirements, evaluation criteria)
• Convocatoria — the public call / tender notice
• Junta de aclaraciones — clarification meeting between buyer and bidders
• Propuesta técnica / económica — technical and financial bid
• Fallo — the award decision
• Testigo social — "social witness," an independent civil society observer required for large procurements
• Contrato marco — framework agreement used for recurring purchases
• Dependencia / entidad — contracting authority (ministry / decentralized agency)

Hook lets you query CompraNet in plain English — "federal hospital IT tenders closing this month," for example — and automatically matches the Spanish terms behind the scenes.

Procurement procedures in detail

The four main procedure types each have distinct timelines, competition levels, and documentation burdens:

• Licitación pública nacional — open tender restricted to Mexican suppliers or goods of Mexican origin. Minimum 15 calendar days between convocatoria and bid opening. Full bases, junta de aclaraciones, and formal fallo required.
• Licitación pública internacional bajo la cobertura de tratados — open to suppliers from countries with a trade agreement. Applies above the treaty threshold. Minimum 20 days timeline. Often the cleanest path for foreign bidders from USMCA/CPTPP/EU.
• Licitación pública internacional abierta — open to any country. Used when no domestic or treaty-country supplier is available, or when procuring under an international loan (e.g. World Bank, IDB).
• Invitación a cuando menos tres personas — the buyer selects and invites at least three suppliers. Faster than open licitación but still requires written bids and a fallo. Used in the middle threshold band.
• Adjudicación directa — single-source award. Used below the low threshold or in specific justified exceptions (sole source, emergency, national security, etc.). Must still be published on CompraNet above a minimum value.

How to search CompraNet effectively

CompraNet's native search supports filtering by dependencia, estado (status), procedure type, and CUCoP code — Mexico's Clasificador Único de las Contrataciones Públicas, the federal equivalent of EU CPV codes. The interface has moved between legacy and modern views through the SHCP transition, so filter availability varies.

Tips for effective searching:

• Use CUCoP codes whenever possible — far more precise than keyword search across Spanish terms
• Filter by dependencia to track specific buyers; IMSS alone can justify a full-time monitoring workflow
• Check the Programa Anual de Adquisiciones (PAAAS) of each entity — published early in the fiscal year, it previews nearly every upcoming licitación
• Monitor fallos (award decisions) to understand pricing, incumbents, and recurring framework contracts
• Watch for contratos marco — increasingly used by SHCP for recurring purchases and simplifying participation
• For works, review the Programa Anual de Obras Públicas (PAOP) alongside the PAAAS

The limitations of CompraNet's native search are well-known: inconsistent interface versions, Spanish-only operators, and no cross-entity alerting. Hook's semantic search sits on top of the full tender corpus and bridges these gaps — one query, English, all dependencias.

Common questions about CompraNet

How Hook helps vendors targeting Mexico

Hook is an AI-powered search tool that indexes CompraNet convocatorias, invitaciones, fallos, and contratos. Instead of navigating the Spanish portal (and its shifting URLs) manually, you search in plain English.

Example queries Hook understands:

• "Show me IMSS medical equipment licitaciones closing in the next 30 days"
• "Which Pemex oilfield services contracts were awarded last quarter?"
• "Find CFE transmission works above MXN 50 million"
• "SEDENA construction adjudicaciones directas over MXN 10M in 2026"
• "Federal IT framework contracts (contratos marco) open now"

Hook returns structured results: expediente, dependencia, title, estimated value in MXN, procedure type, threshold tier, and closing date — ready for direct import into your pipeline. No manual Spanish reformatting, no guessing whether the portal URL changed again.

For companies expanding across Latin America, Hook provides a single search layer across Mexico (CompraNet), Colombia (SECOP II), Chile (Mercado Publico), Brazil (ComprasNet), and other regional systems — turning weeks of manual monitoring into a single English query.
