What is the EU-Mercosur Trade Agreement?

The partnership agreement between the European Union and Mercosur (Argentina, Brazil, Paraguay, and Uruguay) represents one of the most significant developments in trade and regulatory relations between the two blocs.

The legal framework currently under discussion is based on two distinct instruments: the EU–Mercosur Partnership Agreement (“EMPA”), which is broader in nature, and the Interim Trade Agreement (“iTA”), focused on trade and investment disciplines. This architecture allows for a phased application with progressive legal effects as the respective internal approval and ratification procedures are concluded.

The provisional application effective as of May 1, 2026, marks the beginning of a new phase in EU–Mercosur relations, but this does not mean the overall agreement has come into full effect. This distinction is relevant because it helps correctly frame the legal moment when companies begin to feel the practical effects of the new regime, particularly regarding trade, investment, rules of origin, and contractual predictability.

Opportunities

Opportunities for Portuguese Companies

For Portuguese companies, the agreement could translate into better access conditions to markets with strong growth potential, particularly in sectors such as metalworking, industrial equipment, technology, energy, and niche agrifood. Increased regulatory and contractual predictability tends to favor commercial expansion, the formation of new partnerships, and an increase in long-term sales.

At the same time, this new framework requires greater attention to contract drafting, guarantee regimes, payment clauses, and the definition of effective collection and debt recovery mechanisms, especially in operations where the risk of default is higher.

Opportunities for Mercosur Companies in Portugal

The agreement reinforces Portugal's role as a gateway for Mercosur companies wishing to invest in the European Union. In areas such as technology, aeronautics, energy, and specialized services, there are already signs of increased interest from South American investors in Portugal.

In this context, the legal framework for market entry, corporate structuring, formalization of contracts, and risk management associated with commercial operations gain particular relevance, especially when activity takes place across different jurisdictions.

What Changes for Credit Management and Collection

In an international context underpinned by greater geopolitical instability and increasing tensions over supply chains, logistical costs, and commercial predictability, the need to define solid credit policies also increases. This includes contracts with clear payment clauses, guarantees, and competent jurisdiction, as well as collection mechanisms capable of responding to defaults in a cross-border context.

Prevention remains essential, but the ability to act quickly in debt recovery also becomes decisive for preserving cash flow and reducing risk exposure.

How Castilho Empowers Its Clients

Castilho positions itself as a leading partner for companies looking to seize the opportunities of the EU-Mercosur agreement without neglecting the legal framework and commercial risk.

For Mercosur companies wishing to invest in Portugal, Castilho provides support in the legal structuring of entry into Europe, customs and documentary support for imports, product regulatory compliance, and contractual protection and mitigation of commercial risk.
