In a rapidly evolving geopolitical landscape marked by rising tensions and global economic challenges, the European Union is accelerating efforts to diversify its trade partnerships. One of the most significant recent developments is the signing of the EU-Mercosur Partnership Agreement (EMPA, or the Agreement) and the Interim Trade Agreement (iTA) on 17 January 2026, after more than 25 years of negotiations between the EU and four Mercosur countries: Argentina, Brazil, Paraguay, and Uruguay. The Agreement is historic both in market size and scope. Together, the EU and Mercosur represent more than 700 million consumers, and upon entry into force, the iTA will eliminate import duties on over 90% of goods traded between both blocs. Yet the path forward is not without obstacles; we discuss key developments that are shaping the Agreement’s trajectory below.
Understanding the Agreement’s structure and how to claim trade benefits
The EMPA encompasses both political cooperation and trade components, thus requiring ratification by all EU member states before it can enter into force. In contrast, the iTA covers only the trade and investment aspects of the EMPA and can therefore be ratified at the EU level alone. This two-track approach enables trade-related commitments to take effect ahead of the EMPA’s full implementation. Only goods originating in the respective territories may benefit from preferential treatment under the iTA. Accordingly, the Agreement includes provisions governing the determination of origin, which assess whether products have been wholly obtained in the territory, produced exclusively from originating materials, or manufactured incorporating non-originating materials that fulfil the product-specific rules of origin.
The iTA establishes a self-certification system based on “statements on origin” rather than formal certificates issued by governmental authorities. The statement must appear on the invoice, delivery note, or other relevant commercial document; it must generally bear the original, handwritten signature of the exporter; and it must be submitted within its validity period. Having a statement alone is not sufficient: importers must be prepared to submit, at any time upon request by customs authorities (even after the import happened), all appropriate documents proving the originating status of the imported products. Any products exported under tariff rate quotas granted by the EU must also be accompanied by an official document issued by the Signatory Mercosur State.
The iTA includes several mechanisms to ensure that businesses can enjoy the benefits of the Agreement and protect themselves from unwarranted impacts. Businesses can request an investigation in the event of a threat of serious injury to their industry due to the increase of bilateral trade (see the bilateral safeguard clause below); they can request advance rulings with regard to tariff classification or origin (and, to a degree, also on valuation); and the Agreement foresees administrative and judicial appeal mechanisms against administrative actions, rulings, and decisions of customs or other authorities affecting the trade between the two blocs.
Sensitivities and the road to provisional application
The Agreement has faced strong opposition from agricultural stakeholders and environmental advocates in the EU. Critics argue that it would expose EU farmers to unfair competition from imports produced under weaker labour, environmental, animal welfare, and pesticide standards, threatening farm livelihoods and EU food security. Concerns were also raised about the Agreement’s unprecedented “rebalancing mechanism”, which allows either party to demand compensation or adjust tariff concessions if the other party introduces new laws on environmental, climate, or health topics. Opponents warn that this provision could undermine EU sovereignty by allowing Mercosur countries to challenge and seek compensation for EU sustainability legislation, including measures on deforestation (EUDR), the Carbon Border Adjustment Mechanism (CBAM), and corporate sustainability due diligence (CSDDD).
On 21 January 2026, these concerns prompted the European Parliament to adopt a motion to request the Court of Justice of the European Union to assess the compatibility of the Agreement with the EU Treaties. The Parliament has indicated that it “will be able to vote to grant consent (or not) to the Agreement” only after the Court delivers its opinion. As this is expected to take up to two years, this creates a significant procedural hurdle for the Agreement’s conclusion. Despite the request for an opinion on the legality, the European Commission may still proceed with the provisional application of the Agreement; however, doing so would go against standard practice and enter politically sensitive territory.
Bilateral safeguard clause
On 10 February 2026, the European Parliament furthermore approved a new regulation establishing enhanced safeguard clauses to protect the EU agricultural sector from potential market disruptions resulting from trade liberalisation under the Agreement. The Safeguard Regulation allows the EU to temporarily suspend tariff preferences on agricultural imports from Mercosur countries if a surge in imports threatens to harm EU producers.
The safeguard mechanism introduces stricter thresholds than originally proposed by the Commission. An investigation into protective measures will be triggered when imports of sensitive agricultural products –including poultry, beef, eggs, dairy, garlic, citrus, honey, sugar, and biodiesel – increase by 5% on a three-year average (reduced from the Commission’s proposed 10% per year) and when import prices fall 5% below the relevant domestic price. Investigations may also be initiated at the request of a member state or industry representatives in cases of threatened serious injury. The Commission is required to report to Parliament at least every six months on the impact of sensitive product imports. Once formally adopted by the Council, the Regulation will enter into force alongside the iTA.
Looking ahead
The EMPA represents a landmark achievement in international trade diplomacy, particularly given the scale and economic significance of the markets involved. However, its path to implementation remains uncertain amid ongoing internal divisions within the EU. The recent referral for review by the Court of Justice constitutes an important setback for the European Commission, adding complexity to an already fraught ratification process. As the Agreement navigates these remaining procedural and political hurdles, companies operating across both trade blocs would be well-advised to monitor developments closely and assess potential implications for their cross-border operations. Looking ahead, the EU-Mercosur experience also signals a shift in how the EU approaches trade agreements going forward: frustrated by lengthy ratification timelines, the European Commission has proposed a “possible accelerated procedure” that would shorten the process from conclusion of negotiations to entry into force from 23 months to just 13 months, with trade deals with Indonesia and India identified as potential test cases.
What businesses trading between the EU and Mercosur should consider next
Our International Trade team has capabilities across Europe and Latin America, and we are well positioned to assist you in understanding and leveraging the mechanisms and advantages provided by the Agreement.
While the Agreement is pending ratification, businesses should use this period to prepare. This includes:
- Supply chain planning and impact assessment: Analyse your supply chains to identify products that may benefit from preferential tariff treatment and those that may require adjustments to meet origin requirements, and assess the potential duty benefits.
- Origin review: Assess whether your products qualify as “originating” under the Agreement’s rules and review your evidentiary documentation for origin determination purposes, including statements on origin, supplier declarations, and supporting records.
- Tariff classification analysis: Review the tariff classification of goods that could benefit from potential duty savings under the Agreement and seek advance rulings where appropriate.
- Compliance gap analysis: Identify gaps in your current documentation and record-keeping practices against the iTA’s requirements.
- Regulatory monitoring: Keep on top of developments in the ratification process, the Court of Justice proceedings, and any changes to related EU legislation (e.g., EUDR, safeguard regulations).
- Regulatory compliance: Comply with standalone EU regulations (e.g., EUDR, CBAM, CSDDD) that will remain in effect regardless of the Agreement’s status, ensuring your products meet all necessary standards for market access.
Once the iTA enters into force, businesses should ensure ongoing compliance and maximise the Agreement’s benefits:
- Authorised Economic Operator (AEO) applications: Consider applying for AEO status to benefit from reduced documentation, fewer inspections, faster release times, and other trade facilitation advantages.
- Customs broker management: Ensure that customs brokers are appropriately instructed to process preferential duty claims and ensure compliance with origin evidencing requirements.
- Safeguards: Protect your interests in safeguard investigations, whether you are an EU producer seeking protection or an exporter affected by potential safeguard measures.
- Customs disputes and appeals: File administrative and judicial appeals against customs decisions affecting your trade.
Should the Court of Justice of the EU issue an adverse opinion or the ratification process otherwise fail, businesses will need to reassess their strategies. In the absence of the Agreement, standard customs rules – including non-preferential origin requirements, most-favoured-nation (MFN) tariff rates, and existing regulatory and market access limitations – would continue to apply. Ensuring compliance with these requirements remains essential to avoid disruptions and hurdles in accessing the EU and Mercosur markets.
- Non-preferential origin compliance: Assess compliance with non-preferential origin rules and documentation requirements that apply in the absence of a preferential trade agreement.
- MFN tariff assessment: Analyse the impact of continued MFN tariff rates on your products.
