The EU-Mercosur Interim Trade Agreement provisionally applies from 1 May, opening the first tariff reductions and market-access benefits for European exporters while the wider partnership agreement awaits full ratification.
The EU-Mercosur Interim Trade Agreement begins provisional application today, bringing into effect the first trade provisions of a wider partnership between the European Union and Mercosur countries.
The arrangement covers trade between the EU and Argentina, Brazil, Paraguay and Uruguay. It follows the political agreement reached in December 2024, the adoption of Council decisions in January 2026, and the subsequent signing of both the broader EU-Mercosur Partnership Agreement and the Interim Trade Agreement. The Commission’s EU-Mercosur agreement page states that the interim trade instrument applies provisionally from 1 May 2026.
The immediate effect is commercial rather than diplomatic. The interim agreement allows tariff reductions and other trade provisions to begin before the full partnership agreement completes all required ratification procedures. Once the wider agreement enters into force, the interim instrument will be repealed and replaced by the full EU-Mercosur Partnership Agreement.
For EU exporters, the most visible change is the start of phased tariff reductions across several industrial sectors. A Commission factsheet on provisional application states that duties on EU electric and hybrid vehicle exports to Mercosur fall immediately from 35 per cent to 25 per cent. Duties on internal combustion engine cars are reduced from 35 per cent to 17.5 per cent.
The automotive sector is one of the clearest beneficiaries of the first day of provisional application, but the agreement is not confined to vehicles. Tariffs on car parts are to be gradually dismantled for 90 per cent of EU exports over a 10-year period, with an initial cut on day one. Machinery and appliances, pharmaceuticals and textiles are also covered by phased tariff-reduction schedules.
For machinery and appliances, existing duties of 14 to 20 per cent are to be gradually dismantled for 93 per cent of EU exports over a 10-year period in most cases. Pharmaceutical tariffs of up to 14 per cent begin a transition towards zero for 90 per cent of EU exports. Textile duties of 35 per cent begin an eight-year transition to zero for all EU textile exports to Mercosur.
The services sector is also covered. The agreement provides for market-access opportunities in areas including financial services, postal services and telecommunications. It also contains provisions on temporary business movement, allowing service suppliers such as intra-corporate transferees and contractual suppliers to enter the EU and Mercosur countries temporarily for business purposes.
Public procurement is another area affected by the agreement. EU companies gain access to government contracts in Argentina at federal level, in Brazil at federal and sub-central level, and in Uruguay at federal level, subject to exceptions. Access to procurement in Paraguay is due to follow within three years.
The Commission says the agreement is intended to reduce both tariff and non-tariff barriers. It includes provisions on technical barriers to trade, labelling, international standards, conformity assessment, dispute settlement and support for small and medium-sized enterprises through the EU’s Access2Markets portal.
The economic relationship is already substantial. According to the Commission, the EU is Mercosur’s second-largest trading partner in goods, with EU exports to the region worth €57 billion in 2024. The EU also accounts for a quarter of Mercosur’s trade in services, with EU service exports to the region amounting to €29 billion in 2023. EU foreign direct investment stock in Mercosur stood at €390 billion in 2023.
The agreement remains politically sensitive, particularly in relation to agriculture. EU farming groups and several national political actors have raised concerns over imports of agricultural products, market pressure and production standards. In October 2025, the Commission proposed additional safeguards intended to strengthen protections for EU farmers in the context of the EU-Mercosur agreement.
Those concerns are likely to continue as the agreement begins to operate. Provisional application gives exporters immediate access to certain benefits, but it also brings closer scrutiny of how the market effects are distributed across sectors and member states. Industrial exporters may see new opportunities in a large South American market, while agricultural interests will continue to monitor import volumes, safeguards and enforcement.
The text of the agreement sets out the legal framework for trade liberalisation, rules of origin, customs procedures, services, procurement and dispute settlement. The practical consequences will depend on how quickly businesses adjust supply chains, pricing and market-entry strategies to the new tariff schedules.
For Brussels, the start of provisional application marks the transition from negotiation to implementation. The EU-Mercosur deal is now no longer only a political commitment or a pending ratification file. From today, parts of it begin to shape real trade conditions between Europe and South America.
