- EU–Mercosur Agreement: what is it?
Since 1 May 2026, the interim trade agreement between the European Union and Mercosur has been provisionally applied.
After more than 25 years of negotiations, this topic is no longer only political. It is now operational for companies that import, export or work with South America.
The agreement concerns trade between the European Union and several Mercosur countries, including Brazil, Argentina, Uruguay and Paraguay.
Its objective is clear: to facilitate trade through a gradual reduction of customs duties and a more predictable framework for companies.
However, this change does not mean that formalities disappear.
To benefit from tariff advantages, goods must meet specific conditions. Rules of origin, REX status, customs supporting documents and documentary compliance remain essential.
This is why the EU–Mercosur Agreement directly changes the way international logistics must be approached.
In 2026, logistics performance no longer depends only on transport. It also depends on a company’s ability to anticipate customs requirements, secure its documents and integrate rules of origin from the start.
Why does the EU–Mercosur Agreement change the rules?
The EU–Mercosur Agreement aims to facilitate trade between the European Union and Mercosur countries.
It notably provides for a gradual reduction of customs duties on many products. This change can make certain flows more competitive.
But the impact is not limited to transport prices or purchasing costs.
In reality, the agreement changes the entire way logistics performance is assessed. A company must now analyse several elements before importing or exporting:
- applicable customs duties;
- rules of origin;
- required documents;
- REX status;
- customs clearance times;
- goods compliance;
- real logistics costs.
In other words, competitiveness no longer depends only on transport. It also depends on customs expertise.
Brazil, a key player in EU–Mercosur flows
Within Mercosur, Brazil plays a major role.
It concentrates a large share of trade with the European Union. Its role is therefore central to the operational impact of the EU–Mercosur Agreement.
For European companies, this can create new opportunities. Some goods may become more accessible. Some suppliers may become more competitive. Some trade routes may also become more attractive.
However, these opportunities must be studied carefully.
A tariff advantage is not always enough to secure an international shipment. Companies must also check origin conditions, customs formalities and the documents to be provided.
Customs duties: a real advantage, but under conditions
The reduction of customs duties is one of the most visible aspects of the EU–Mercosur Agreement.
On paper, it can help companies reduce costs. But in practice, this advantage depends on several conditions.
To benefit from preferential tariff treatment, goods must comply with the rules of origin provided for in the agreement.
This means that a company cannot simply import or export a product from a Mercosur country and automatically apply a reduced duty.
It must prove that the goods genuinely originate from the relevant territory, according to the criteria set out.
This is where customs becomes essential.
An error in origin, an incomplete declaration or a missing document can call the tariff advantage into question. In some cases, this can lead to additional duties, delays or blocked goods.
Rules of origin and REX status: two points to anticipate
Rules of origin are at the heart of the EU–Mercosur Agreement.
They determine whether goods can benefit from reduced or eliminated customs duties.
For European exporters, REX status can also play an important role. It allows a registered company to self-certify the preferential origin of its products under certain trade agreements.
But this status should not be treated as a simple formality.
The company must be able to justify the declared origin. It must keep the necessary evidence. It must also ensure that its products meet the applicable criteria.
Without this preparation, the tariff advantage can become a risk.
A direct impact on the supply chain
The EU–Mercosur Agreement can change companies’ logistics decisions.
Previously, some flows could be less attractive because of customs duties or administrative complexity. With the agreement, these flows may become more competitive.
This can influence several decisions:
- choosing a new supplier;
- reviewing a purchasing strategy;
- comparing several sourcing countries;
- adapting transport routes;
- anticipating customs clearance times;
- integrating compliance from the commercial negotiation stage.
The supply chain must therefore be considered earlier.
Companies can no longer wait until shipment to ask the right questions. They must integrate customs rules from the purchasing, sales or contractual negotiation phase.
Logistics performance also depends on customs
In an international shipment, transport remains important.
But it is not enough.
Goods can be transported quickly and still be blocked at customs. A transport cost can be competitive, but lose its value if customs duties are poorly anticipated. A supplier may offer a good price, but create a risk if origin documents are not reliable.
This is why logistics performance must be analysed as a whole.
It depends on transport, but also on compliance, documentation, rules of origin, declarations and the right choice of partners.
In this context, the role of the freight forwarder and customs representative becomes even more strategic.
Why should companies anticipate now?
The EU–Mercosur Agreement does not only concern large companies.
It can also affect SMEs that import, export or work with international suppliers.
Companies that anticipate can gain a structural advantage.
They can identify the products concerned, check rules of origin, review their commercial contracts and adapt their logistics organisation.
Conversely, companies that wait may suffer from the changes.
They may discover too late that a product does not meet origin conditions. They may lose a tariff advantage. They may also face delays or unexpected costs.
How to prepare your logistics for the EU–Mercosur Agreement
To secure their flows, companies should start by analysing their current operations.
The first step is to identify the goods concerned. Then, they must check customs codes, applicable duties and rules of origin.
It is also important to review the documents used in international trade: commercial invoices, certificates, proof of origin, transport documents and customs declarations.
Finally, companies must ensure that their teams and partners understand the new requirements.
Good preparation helps avoid mistakes. It also makes it possible to turn the EU–Mercosur Agreement into a real competitive advantage.
