EU-Mercosur Agreement 2026: what changes for Spanish exporters and importers

Key data

Spanish companies with commercial operations in Mercosur are already operating under the new rules. The Interim Trade Agreement EU-Mercosur [2026/868], published on 15 April 2026 in the EU Official Journal, enters into provisional application immediately. This means there is no need to wait for full parliamentary ratification: the commercial provisions are binding from now.

The agreement covers trade relations with four countries: Argentina, Brazil, Paraguay and Uruguay. Any Spanish company importing or exporting goods with these markets must act now to take advantage of the benefits or adapt to new competition.

What does this regulation establish?

The interim agreement regulates trade in goods between the European Union and the four Mercosur countries. Its main elements are:

• Tariff reductions: The agreement provides for possible tariff reductions on imports and exports between both blocs. Companies must verify whether their products benefit from reduced rates.
• New market access rules: Updated conditions are established for European products to enter the markets of Argentina, Brazil, Paraguay and Uruguay, and vice versa.
• Tariff quotas: The agreement sets quotas (reduced-tariff quotas) for certain product categories. Exceeding those quotas means paying ordinary rates.
• Rules of origin: To benefit from tariff advantages, products must comply with the rules of origin established in the agreement. Without proper documentation, preferential rates do not apply.
• Provisional application: The commercial provisions are binding from publication, without waiting for full formal ratification by all EU national parliaments.

The sectors most exposed to changes are agriculture, automotive, processed foods and services, although the agreement affects all trade in goods between both blocs.

Economic and operational impact

The impact of the agreement has two sides for Spanish companies:

The most immediate operational impact is the need to review the tariff classification of products, verify that origin requirements are met and update customs procedures to benefit from the new preferential rates.

Who does it affect?

• Spanish exporting companies that sell products to Argentina, Brazil, Paraguay or Uruguay.
• Spanish importing companies that purchase raw materials, agricultural products or manufactures from Mercosur countries.
• Agricultural and agri-food sector: both producers who export and those competing with Mercosur imports.
• Automotive sector: manufacturers and component suppliers with commercial operations in Brazil or Argentina.
• Processed food sector: companies that export or import products originating from Mercosur.
• Service companies with presence or clients in Mercosur countries, which may see their market access conditions modified.
• Foreign trade, logistics and purchasing departments of any company with a supply chain linked to Mercosur.
• Customs and tax advisors managing import or export operations with these countries.

Practical example

A Spanish automotive component manufacturer that regularly exports to Brazil previously operated with general tariffs applicable to its products. With the provisional application of the EU-Mercosur agreement, those components can benefit from reduced tariff rates at destination, provided the company proves that its products comply with the rules of origin established in the agreement.

If the company does not review its origin documentation or update its customs declarations, it will continue to pay the ordinary tariff and lose the competitive advantage over European competitors who have adapted. The first step is to verify the tariff code of each exported product and check whether it falls within the quotas with reduced rates or if a general reduction applies directly.

Conversely, a Spanish importer of meat or soybeans from Argentina or Brazil must analyze whether the new tariff quotas allow them to reduce procurement costs, and whether their European competitors are already taking advantage of that benefit.

What should companies do now?

1. Identify all commercial flows with Mercosur: List the products imported or exported with Argentina, Brazil, Paraguay and Uruguay and their current tariff codes.
2. Review the new applicable tariffs and quotas: Consult the agreement text to verify whether the company's products benefit from tariff reductions or are subject to quotas with limited allocation.
3. Verify compliance with rules of origin: Without proving preferential origin, reduced rates do not apply. Review the origin documentation of each product and update certificates if necessary.
4. Update customs procedures: Inform the logistics department and customs agents of the new applicable rates so they apply them correctly in import and export declarations.
5. Evaluate competitive impact: Analyze whether the entry of Mercosur products with reduced tariffs affects the company's competitive position in the Spanish or European market, especially in agriculture and processed foods.
6. Consult with a foreign trade specialist advisor: Given the technical complexity of quotas and rules of origin, it is advisable to have specialized advice to avoid losing benefits or making errors in customs declarations.
