EU-Mercosur Deal Puts South America-Europe Cargo Flows in Focus

The EU-Mercosur interim trade agreement began provisional application on 1 May 2026, giving freight forwarders a new set of tariff rules to track across an already substantial Atlantic trade lane. Any effect on cargo volumes is likely to build gradually: demand, production, prices and companies’ ability to use preferential tariffs will all shape which shipments become more attractive.

The scale is significant. In 2024, the European Union imported €56 billion in goods from Argentina, Brazil, Paraguay and Uruguay, and exported €55.2 billion to the four founding Mercosur members. Primary goods made up most EU imports, while manufactured products dominated EU exports. That established exchange gives logistics teams a useful baseline as businesses assess the new terms.

Tariffs meet origin and customs procedures

The EU and Mercosur reached a political agreement on their Partnership Agreement in December 2024. They signed that agreement and an Interim Trade Agreement in January 2026. The interim deal now applies provisionally; the wider Partnership Agreement is expected to replace it after completing its ratification process.

The framework covers tariffs, rules of origin, customs and trade facilitation, technical barriers, sanitary and phytosanitary measures, and sustainable development. For shippers, lower duties only translate into savings when goods qualify under the origin rules and the required paperwork is in order.

Under EU customs guidance cited for the interim agreement, exporters make a statement on origin to support preferential treatment. Importers can claim that treatment when goods enter or within two years after their release. An incorrect or incomplete declaration can therefore prevent an otherwise eligible shipment from receiving the reduced tariff.

The EU-Mercosur trade agreement could change the commercial appeal of individual lanes and products. It doesn’t guarantee a broad rise in container volumes: the response will depend on market conditions and how quickly companies adjust sourcing, sales and shipping plans.

Potential changes across several cargo types

Existing flows are concentrated in distinct categories. In 2024, primary goods represented 81.3% of EU imports from the four Mercosur countries. Major imports included petroleum and related products, animal feed, coffee, tea and cocoa, metalliferous ores, and oilseeds. In the other direction, 86.6% of EU exports to Mercosur were manufactured goods, including machinery, vehicles, pharmaceuticals and chemicals.

The agreement offers tariff relief for European exports including vehicles, machinery, appliances, pharmaceuticals and agri-food products. Duties on EU electric and hybrid vehicles entering Mercosur fall immediately from 35% to 25%; those on conventional cars are reduced from 35% to 17.5%. Tariffs on many machinery and appliance exports are scheduled for gradual removal.

These changes could support more sales of European equipment and vehicles in South America, with possible freight demand for finished vehicles, components and machinery. The agreement also expands market access for EU agri-food exports such as wine, olive oil and fruit preparations. The European Commission estimates that EU agri-food exports to Mercosur could increase significantly as access expands, though the source gives no volume forecast.

For forwarders, the range of products matters as much as the headline tariff reductions. Different cargoes call for different equipment, handling and routing. The actual effect will become clearer as companies respond to the new costs and buyers’ demand.

Ports and inland links shape the opportunity

Santos is a central gateway for Brazilian trade. The Santos Port Authority reported that the port handled 186.4 million tonnes of cargo in 2025, including about 5.9 million TEU. It connects Brazil with more than 600 destinations and handles cargo from over 200 countries.

Brazil is the EU’s largest trading partner within Mercosur. Two-way EU-Brazil goods trade reached €87.1 billion in 2025, and agricultural products accounted for 42% of Brazil’s exports to the EU. The planned Tecon Santos 10 terminal is intended to raise the port’s container capacity by around 50%, according to the Brazilian government. That expansion may matter if demand grows, but the article doesn’t establish how much additional cargo the agreement will generate.

Buenos Aires and Montevideo serve the Río de la Plata region. Montevideo is also building its role as a regional hub for transit cargo from Paraguay, southern Brazil and Argentina. Its development work has included container-terminal upgrades and dredging the access channel.

Rotterdam and Antwerp-Bruges are major European entry points. From Rotterdam, cargo can continue inland through distribution, warehousing and links to industrial centres. The relevant route doesn’t end at the quay: road, rail and barge connections determine how cargo reaches its destination across Europe.

Gateway choices will vary by shipment origin and destination. A shipper in southern Brazil may face different options from an exporter in Argentina or Paraguay. Inland transport costs, vessel schedules, congestion and equipment availability will all affect which route works best.

What logistics teams should track

Capacity is one early signal to watch. If tariff changes lead to additional shipments in particular commodities, demand could rise for container space, specialised equipment or dependable vessel schedules on specific corridors. Forwarders will need to distinguish sustained changes from seasonal movement.

Origin documentation deserves equal attention. Companies seeking preferential treatment need processes that support accurate statements of origin and timely claims. The tariff reduction alone doesn’t complete the shipment’s commercial case.

Infrastructure and route flexibility will also matter. Santos is expanding container capacity, while Montevideo has pursued terminal and channel improvements. Across the Atlantic, inland links influence how effectively ports can serve shippers beyond their immediate hinterlands.

The agreement is unlikely to remake the Atlantic freight market overnight. The EU and the four Mercosur countries exchanged more than €111 billion in goods in 2024; Brazil alone accounted for €89.5 billion of the EU’s trade with the bloc. For operators, the practical task is to watch how individual products, ports and inland corridors respond as businesses put the new terms to use.
