Mercosur open tenders: Brazil dominates, smaller markets favor construction
Updated: October 25, 2026
Opportia tracks 10,551 open processes across five Mercosur countries. Brazil concentrates most of them, while Uruguay, Argentina, Paraguay and Bolivia offer smaller, more specific niches.
Overview: what today's data show
Opportia is currently monitoring 10,551 open procurement processes across the five countries of Mercosur, the customs union of Argentina, Brazil, Paraguay, Uruguay and Bolivia. The distribution is very uneven:
- Brazil: 10,388 open processes
- Uruguay: 126
- Argentina: 29
- Paraguay: 5
- Bolivia: 3
Brazil also shows the most activity. It has a total value of 119.3 B BRL, 1,663 new processes in the last week and 6,118 closing this week. Uruguay has 88 processes closing this week, Argentina 19, Paraguay 2 and Bolivia 1. None of those four countries registered new processes in the last week.
Where the opportunity is
**Brazil.** The main categories are construction, maintenance and repair (1,506 processes), management, consulting and administration (1,248), health services (882) and vehicles and transport (137). Among the entities with the most processes are ESTADO DO CEARA (74) and SUP. EST. DE LICITACAO (13). The most frequent modality is Pregão - Eletrônico. Brazil's purchasing is spread across federal, state and municipal buyers, which helps explain the volume and variety.
**Uruguay.** Construction, maintenance and repair leads with 33 processes, followed by land, buildings and structures (7), industrial cleaning services (6) and printing, photography and audiovisual (5). Administración de las Obras Sanitarias del Estado, Banco de Previsión Social and Intendencia de Tacuarembó have 9 processes each. The most frequent modality is Licitación Abreviada. The total value appears as 0 UYU, which most likely means values are not reported in the source, not that the processes are free of cost.
**Argentina.** Of the 29 open processes, the data list only one category, lighting and electrical equipment (1). Administración de Parques Nacionales and Estado Mayor General de la Armada have 4 each, and Estado Mayor General del Ejercito has 2. The most frequent modality is Licitación Pública.
**Paraguay.** There are few processes, but the total value is 229.0 B PYG. Construction, maintenance and repair accounts for 3 and furniture for 1. The MOPC, MITIC and MSPBS have 1 process each, and the most frequent modality is Licitación pública internacional.
**Bolivia.** All 3 processes belong to the Banco Central de Bolivia (BCB), under the modality Apoyo nacional a la producción y empleo (ANPE).
What to watch and how to prepare
- Check closing dates first. With 6,118 processes closing this week in Brazil, many opportunities have little time left, so prioritize those where you can realistically prepare a compliant bid.
- In Brazil, become familiar with the electronic auction format and with how each state or municipal buyer publishes its requirements.
- In Uruguay, look at construction and maintenance, and follow the repeat buyers listed above.
- In Paraguay, read the terms of international public tenders carefully, since the few processes carry large values.
- Consider local partners, especially in markets with specific rules for national suppliers, such as Bolivia's ANPE modality.
- Do not rely on aggregate values. Where the data show 0, review the original documents to confirm the budget.
- Verify requirements, documents and deadlines in each official notice before committing resources.
Scope of these data
These figures cover open processes that Opportia monitors and do not represent the entire Mercosur market. Some processes, buyers or portals may not be included, and fields such as value or category are not always complete. Use this analysis as a starting point for exploration, and always confirm details in the official source of each process.
