Mercosur-EU Agreement: Trade Law Analysis for Businesses

Updated October 2026.

The Mercosur-EU agreement has been provisionally applied since 1 May 2026 between the European Union and the four Mercosur States that signed it — Argentina, Brazil, Paraguay and Uruguay — but it has not yet entered definitively into force. Signed in Asunción on 17 January 2026, after negotiations concluded on 6 December 2024, the treaty is split into two instruments: an interim Trade Agreement, which contains the trade pillar and already produces effects, and a broader Partnership Agreement, which still depends on ratification by the EU Member States. This analysis examines the legal architecture of the agreement, its current status, the main trade commitments and what they mean in practice for companies operating between Brazil and Europe, particularly Germany.

A more detailed analysis in Portuguese, with the tariff schedules, the full quota table and the internal implementing rules adopted in Brazil, is available in our article Acordo Mercosul-União Europeia: o que muda para empresas em 2026.

Legal architecture of the Mercosur-EU agreement

On 3 September 2025, the European Commission submitted to the Council and to the European Parliament proposals concerning two distinct instruments. The first is the EU-Mercosur Partnership Agreement (EMPA), which combines the trade pillar with political dialogue and cooperation. Because it covers matters that do not fall within the exclusive competence of the Union, it must also be ratified by the national parliaments of the EU Member States.

The second is the interim Trade Agreement (iTA), which contains only the trade provisions. As the common commercial policy is an exclusive competence of the EU, this instrument can be concluded and applied by the Union without ratification by national parliaments, and it applies only between the EU and those Mercosur States that have ratified it. Its 23 chapters cover trade in goods, rules of origin, customs and trade facilitation, technical barriers to trade, sanitary and phytosanitary measures, trade remedies, bilateral safeguards, services and establishment, current payments and capital movements, government procurement, intellectual property, small and medium-sized enterprises, competition, subsidies, state-owned enterprises, trade and sustainable development, transparency, exceptions, dispute settlement and institutional and final provisions. The full text is published on the European Commission’s website.

Bolivia, a full member of Mercosur since July 2024, is not a party to the agreement, whose negotiations were largely concluded before its accession. According to the European Commission, the agreement creates a trade area of around 700 million people.

Is the Mercosur-EU agreement in force?

The agreement is being applied provisionally; it is not definitively in force. Argentina, Brazil, Paraguay and Uruguay notified the completion of their ratification procedures, which allowed provisional application of the interim Trade Agreement to begin on 1 May 2026 with all four countries. Since then, exporters and importers may use the tariff preferences, provided they meet the rules of origin.

In Brazil, the National Congress approved the interim Trade Agreement by Legislative Decree No. 14 of 17 March 2026; the Brazilian Government deposited its instrument of ratification on 18 March 2026; and Decree No. 12,953 of 28 April 2026 promulgated the agreement, recording that Brazil would apply it from 1 May 2026.

What is still pending

Definitive entry into force on the EU side requires a Council decision preceded by the consent of the European Parliament (Article 218(6) of the Treaty on the Functioning of the European Union). On 21 January 2026, the European Parliament decided, by 334 votes to 324 with 11 abstentions, to request an opinion from the Court of Justice on the compatibility of the agreement with the Treaties. The request is registered as Opinion 1/26. Under Article 218(11) TFEU, if the opinion is adverse, the agreement may not enter into force unless it is amended or the Treaties are revised. As of this update, the Court has not delivered its opinion, and Parliament’s consent therefore remains pending.

The Partnership Agreement follows a longer path, as it also depends on ratification by the national parliaments of the EU Member States. In the meantime, trade relations between the two blocs are governed by the interim Trade Agreement.

The practical consequence is that the trade effects — tariffs, quotas, rules of origin — are already available, but their continuity depends on decisions of the EU institutions that may be influenced by the outcome of the Court’s opinion. Companies planning long-term investments or contracts on the basis of the preferences should take this into account when allocating contractual risks.

Market access and tariff liberalization

Liberalization is asymmetric in favour of Mercosur. According to the Brazilian Government’s official summary, the EU will eliminate import duties on approximately 95% of goods, representing 92% of the value of EU imports from Brazil, either immediately or linearly over 4, 7, 8, 10 and 12 years. Around 3% of goods, corresponding to 5% of import value, are subject to tariff-rate quotas or other forms of access. Mercosur will eliminate duties on approximately 91% of goods and 85% of the value of Brazilian imports from the EU, immediately or linearly over 4, 8, 10 or 15 years.

The automotive sector received specific treatment on the Mercosur side: tariff elimination for electrified vehicles takes place over 18 years, for hydrogen-powered vehicles over 25 years and for vehicles incorporating new technologies over 30 years. The category of each product is set out in Annex 2-A (tariff elimination schedules), by tariff line, and it is this annex that determines the preferential duty applicable to a given transaction.

Agricultural tariff-rate quotas

Products most sensitive for European farmers were not fully liberalized. For these, the EU opened tariff-rate quotas: within the quota volume a reduced or zero duty applies; above it, the normal duty applies. In several cases the volume increases linearly over five years.

The beef quota is frequently misunderstood: it is not a zero-duty quota, but one with an in-quota duty of 7.5%. Cachaça in bottles of up to two litres will be fully liberalized over four years. Because each quota is limited, supply contracts for products under quota should address what happens if the quota is exhausted and the normal duty applies.

Rules of origin and self-certification

Preferential duties apply only to originating products, that is, products that comply with Chapter 3 of the agreement: goods wholly obtained in the territory of a Party or sufficiently transformed under the product-specific rule set out in Annex 3-B. Since the applicable rule depends on the tariff classification, correct classification is the starting point; a classification error may lead to the wrong rule of origin and to the loss of the preference, with subsequent recovery of duties.

The agreement adopts self-certification: origin is evidenced by a statement on origin made by the exporter, following the model in Annex 3-C. The person issuing the statement is responsible for its accuracy, and supporting documentation — technical data sheets, supplier declarations and cost calculations — should be retained for possible verification by the customs authorities of the importing country.

Safeguards and the rebalancing mechanism

Chapter 9 allows temporary bilateral safeguard measures where liberalization leads to an increase in imports that causes or threatens to cause serious injury to domestic producers. It includes a specific mechanism for the automotive sector (Annex 9-A), which the Brazilian Government presents as an instrument to preserve and promote investment. On the EU side, Regulation (EU) 2026/687 of 11 March 2026 governs the application of the bilateral safeguard clauses to agricultural products and provides for continuous monitoring of imports of sensitive products such as beef, poultry, sugar, ethanol and honey. Safeguard measures generally consist of the temporary suspension of the tariff reduction or the reinstatement of the duty applied to third countries.

A mechanism for the rebalancing of concessions, obtained by Mercosur in the final phase of negotiations, seeks to prevent unilateral measures by one Party from nullifying the negotiated trade concessions. It is particularly relevant in view of European sustainability legislation that conditions market access, although its use depends on the requirements and procedures laid down in the agreement itself.

Services, establishment and government procurement

Chapter 10 governs trade in services and establishment, that is, the setting up of subsidiaries, branches and offices in the territory of the other Party, within the sectors and conditions listed in each Party’s schedules. Unlike a bilateral investment treaty, the interim Trade Agreement contains no investment protection chapter and does not provide for investor-State arbitration. The legal security of European investment in Brazil therefore continues to depend on domestic law, on contracts and on the dispute resolution clauses agreed between the parties.

Chapter 12 grants Mercosur companies preferential access to covered EU public procurement and European companies access to covered procurement in Mercosur countries, according to the entities and value thresholds listed in the annexes. Brazil’s commitments preserve policy space for industrial development, innovation and small businesses, fully exclude purchases by the Unified Health System (SUS) and maintain the preference margins provided for in federal legislation. In Brazil, covered tenders remain governed by Law No. 14,133/2021.

Sustainability and the EU Deforestation Regulation

Chapter 18 deals with trade and sustainable development and reaffirms multilateral commitments such as the Paris Agreement. Tariff preferences do not exempt exporters from EU legislation applicable to imports. The most relevant for agribusiness is the EU Deforestation Regulation (EUDR, Regulation (EU) 2023/1115), which makes the placing on the EU market of cattle, cocoa, coffee, oil palm, rubber, soya, wood and listed derived products conditional on proof that they were produced without deforestation after 31 December 2020 and in accordance with the law of the country of production. After two postponements, the obligations apply from 30 December 2026 for medium and large operators and, as a rule, from 30 June 2027 for micro and small enterprises. Details are set out in our article on the EUDR for Brazilian exporters (in Portuguese).

Dispute settlement

Chapter 21 provides for a State-to-State dispute settlement mechanism, with consultations, an arbitration panel and mediation. It can be triggered by the Parties to the agreement, not by companies. A company affected by a measure inconsistent with the agreement depends on its government bringing the matter forward.

Disputes between companies — on delivery, quality, payment or origin of goods — remain subject to the contract. Between parties established in Contracting States, such as Brazil and Germany, the United Nations Convention on Contracts for the International Sale of Goods (CISG) applies unless excluded by the parties. International arbitration is frequently chosen in such contracts, and the arbitration clause should define the institution, the seat, the language and the applicable law; see our article on international arbitration in Brazil (in Portuguese).

Implications for Brazil-Germany business

Germany, which supports the agreement, is among the European economies with the closest industrial ties to Brazil. According to European authorities, machinery, electrical equipment, chemicals and pharmaceuticals are among the goods benefiting from tariff elimination, which directly concerns the supply chains linking the two countries. For German companies already established in Brazil, and for Brazilian companies supplying European groups, the agreement changes the cost structure of existing operations and raises compliance requirements at the same time.

In practice, provisional application calls for a review of supply, distribution and agency contracts concluded before 1 May 2026: price clauses linked to customs duties; the allocation of costs under the chosen Incoterm; the obligation to provide the statement on origin and its supporting documents; liability for the loss of the preference after an unfavourable verification; and adaptation clauses for the event of a safeguard measure or a suspension of the agreement. Commodity export contracts should also address the data required under the EUDR. The firm’s Stuttgart office, which works with the German Office practice, follows these developments on both sides of the Atlantic.

Conclusion

With provisional application since 1 May 2026, the Mercosur-EU agreement has moved from prospect to legal reality: tariffs are being reduced, quotas are open, rules of origin are enforceable and procurement commitments apply. Definitive entry into force, however, still depends on the Court of Justice’s Opinion 1/26 and on the consent of the European Parliament, and the Partnership Agreement faces a long ratification process. For companies, the task is to use the preferences already available while accounting for this institutional uncertainty: well-documented origin, revised contracts, compliance with the EUDR and European sanitary standards, and integrated tax planning are the conditions for turning tariff reductions into effective market access.
