EU-Mercosur Interim Agreement in Force Since May 1: What DACH SMEs Must Now Review on Supply Chains and Export Tariffs
5 min read
The EU-Mercosur Interim Agreement entered into provisional force on 1 May 2026. For DACH SMEs in mechanical engineering, pharmaceuticals and food processing, this opens up concrete export opportunities – but only if supply chains, proof of origin and customs strategies are adjusted now.
Key Takeaways
- Provisional application from 01 May 2026. The Interim Agreement covers trade elements of the EU-Mercosur treaty before the full agreement is ratified. 90% of EU exports to Mercosur countries will become duty-free in the medium to long term.
- Mechanical engineering and pharma benefit most strongly. German mechanical-engineering companies currently pay up to 35% import duty in Brazil. The agreement envisages a seven-year phase-out to 0%. Pharma export duties in Argentina will drop significantly from the moment the agreement enters into force.
- Proof of origin is mandatory. Without correct origin certificates (EUR.1 or REX declaration), the preferential duty rate does not apply. If you process components from third countries, you must check the value-added quota.
- 24 billion EUR in trade volume affected. The annual EU-Mercosur trade volume with direct DACH links comprises goods from Germany, Austria and Switzerland. For SMEs with fewer than 250 employees, EU export-advisory programmes are available to ease market entry.

What is the EU-Mercosur Interim Agreement? The Interim Agreement is a partial accord between the European Union and the Mercosur bloc (Brazil, Argentina, Uruguay, Paraguay) that brings the trade elements of the full Association Agreement into provisional force. It enables gradual tariff reductions without waiting for full parliamentary ratification by all EU member states.
What this means for DACH SMEs in concrete terms
The impact is sector-specific. Brazil and Argentina are the largest economies in the Mercosur bloc. Brazil alone is Germany’s most important trading partner in Latin America, with bilateral goods trade worth around 10 billion EUR per year.
Current import duties to Brazil (pre-agreement)

Mechanical-engineering imports (average)

Phase-out period for most tariffs
For mechanical-engineering firms, the seven-year timeline is no drawback – it provides planning certainty. Interim steps already take effect in the first year. For companies that have not yet exported directly to Mercosur, now is the time to conduct market analyses.
Five steps to prepare
- Check tariff rates for your products: The EU Market Access Database (MADB) allows you to look up current and planned preferential tariffs for Brazil and Argentina for each HS code.
- Prepare proof of origin: For exports under €6,000, a declaration of origin on the invoice is sufficient. From €6,000 upwards, either an EUR.1 certificate or REX registration with customs is required.
- Verify your products’ value-added share: The agreement applies cumulative rules of origin. If you process pre-products from non-EU countries, you must check whether your depth of processing is sufficient to qualify as “EU originating goods.”
- Inform logistics and customs agents: Existing logistics partners and customs forwarders must be briefed on the new preferential rules. Errors in customs declarations made by the agent are the exporter’s responsibility.
- Use EU export advice: The Enterprise Europe Network (EEN) offers SMEs free initial advice on export markets in South America. Larger mid-sized companies may benefit from engaging a trade lawyer specialising in Latin America.
Opportunities for DACH exporters
- Tariff elimination boosts price competitiveness
- Planning certainty thanks to binding timetable
- Brazil: third-largest export market outside the EU
- Pharmaceutical exports to Argentina immediately cheaper
- SME support via Enterprise Europe Network
Risks and open issues
- Only trade parts for now – no investment protection
- Ratification by EU member states still pending
- BRL/ARS exchange-rate risks remain high
- Proof of origin requires internal effort
- Agricultural products face special rules
The interim agreement is no automatic pass. Tariff benefits apply only if exporters take action – issue proof of origin, file correct customs declarations, brief logistics partners. Those who let the first six months slip by will forfeit competitive advantages that rivals from other EU countries are already leveraging.
What remains unresolved: investment protection and ratification
The interim agreement is deliberately limited to trade. Investment-protection rules, dispute resolution, and sustainability clauses—everything that had made ratification particularly controversial in individual EU member states—are not part of the provisional treaty. That means: if you’re a DACH mid-sized company looking to invest in Mercosur countries, you still don’t have a changed legal framework.
Full ratification by all 27 EU member states is planned for 2027–2028. Several member states—France, Poland, and others—have expressed significant reservations in the past. The interim agreement sidesteps this ratification requirement for the trade-only portion. It is legally stable, yet it is no guarantee for the final comprehensive agreement.
For practical planning: the trade preferences are now legally binding. DACH exporters can base supply chains and export pricing on this foundation. For investment decisions in Mercosur countries, the risk calculus remains unchanged.
„For DACH mid-sized companies in mechanical engineering, pharmaceuticals, and food processing, the deal unlocks concrete export opportunities—but only if supply chains, proof-of-origin documentation, and customs strategies are adjusted now.“
Sectors with urgent action required
Not every DACH sector faces the same impact. Which industries should prioritize evaluating the tariff cuts?
Mechanical and plant engineering: the up-to-35 % tariff reduction to 0 % over a seven-year schedule is the biggest lever. Brazil’s industry is modernizing its manufacturing and automation equipment, putting DACH machinery makers in direct competition with Asian suppliers who previously enjoyed a tariff advantage.
Pharmaceuticals and medical technology: Argentina and Brazil represent large pharmaceutical markets. Import tariffs on specialty drugs and medical devices fall faster than in other categories. If you handle GDPR-like requirements for clinical data, check Brazil’s regulatory landscape in parallel—ANVISA operates its own approval procedures.
Food processing and agricultural machinery: here the picture is mixed. Food-processing machinery follows the machinery-engineering tariff path. For food products themselves, special rules apply—the agreement was politically contentious in this area and includes specific safeguard clauses for European agricultural produce.

Frequently Asked Questions
When exactly do the first tariff reductions come into effect?
The first tariff reductions will take effect immediately upon entry into force on 1 May 2026 in agreed categories. Most mechanical-engineering tariffs follow a seven-year phase-down schedule. Pharmaceuticals and certain chemical products have faster reduction profiles. The exact timelines per HS code are published in the agreement’s preference-tariff annex and accessible via the EU’s MADB database.
Does the agreement also apply to Swiss companies?
No. The EU-Mercosur agreement applies exclusively to EU member states. Switzerland, as a non-EU country, does not benefit directly. Swiss companies can, however, participate indirectly in supply chains via EU subsidiaries or under the EU-Switzerland rules of origin. Direct Swiss exports to Brazil and Argentina remain subject to bilateral trade arrangements.
How burdensome is REX registration for smaller exporters?
REX registration (Registered Exporter System) is free of charge and can be completed online via the German Federal Customs Administration. The administrative effort is low—registration typically takes two to four weeks. For exporters using multiple preference agreements, REX is especially useful because one registration covers all applicable deals. Small exporters shipping goods worth less than €6,000 per consignment may alternatively use an origin declaration on the invoice.
What happens if the full agreement is not ratified?
The interim agreement is legally independent of the full agreement. If the full ratification fails, the interim trade preferences remain in force until a member state actively withdraws—an action that requires its own procedure. For DACH exporters, this means tariff benefits are stable in the medium term. The political risk lies in investment protection and additional regulatory chapters, not in the trade section.
What support is available for SMEs entering the Brazilian market?
Germany Trade & Invest (GTAI) provides free market reports and research support for Brazil, Argentina and Uruguay. The Enterprise Europe Network (EEN) connects SMEs with local partners and distributors. EU co-financing programmes for market-entry measures are also available via COSME successor schemes for companies with fewer than 250 employees. The German Chambers of Commerce (DIHK) and German-Brazilian / German-Argentine Chambers of Commerce (AHKs) offer on-the-ground assistance.
