The provisional implementation of the EU-Mercosur trade agreement on May 1, 2026, initiates a gradual tariff reduction schedule affecting over 700 million consumers across both blocs. While certain agricultural products from Mercosur receive immediate duty-free access to European markets, European automotive and industrial exports face elimination timelines extending to 18 years. Non-tariff barriers, including new EU geolocation requirements for soy imports starting December 2026, may limit the practical impact of tariff reductions for South American exporters.
