Mercosur-European Union Trade Agreement Promulgated by Brazilian Congress, Signaling Imminent Implementation

Brazil’s National Congress formally promulgated the Mercosur-EU trade agreement during a ceremonial session on March 17, 2026, concluding Brazil’s legislative process for the accord. The agreement, signed in January 2026 in Assunção, Paraguay, aims to eliminate tariffs on 91% of European goods imported into Mercosur over 15 years, while the EU will remove tariffs on 95% of Mercosur-origin products across 12 years. The bloc encompasses Argentina, Brazil, Paraguay, and Uruguay, with the EU representing a significant trade partner for Brazil, registering over US$100 billion in bilateral trade in 2025. The accord also covers regulatory areas such as services, investment, intellectual property, public procurement, sustainability, sanitary, and phytosanitary measures, alongside dispute resolution mechanisms.

Post-promulgation, Brazil’s executive branch must ratify the agreement, followed by formal notification to the EU. The treaty enters into force at the start of the month after these procedures are completed. On the European side, legal scrutiny by the Court of Justice is pending after the European Parliament requested an assessment regarding the accord’s alignment with EU treaties. Despite this, the European Commission has indicated provisional application of the trade provisions from May 2026 to avoid delay in economic benefits. Given simultaneous ratifications by other Mercosur countries and the initiation of EU provisional implementation, the trade framework is poised to expand market access, diversify supply chains, and strengthen economic resilience. Brazilian authorities have preemptively established safeguard regulations to mitigate risks of import surges impacting domestic industries, covering both agriculture and manufacturing sectors. The accord is positioned as a significant strategic instrument fostering not only economic growth but also reinforcing cooperation grounded in shared democratic and sustainable development values.
