May 1, 2026, will go down in history as a pivotal date for trade relations between the European Union and MERCOSUR. After years of complex negotiations and intense political debates, the provisional application of the interim Trade Agreement (iTA) is finally a reality. For the past 48 hours, a new trade paradigm has begun to take shape, creating both immense hope and immediate operational challenges. As privileged observers of this matter, we offer you an initial hot take, based on field observations, business reactions, and the first available data. This is not an exhaustive analysis, but a snapshot of the first hours of a new commercial era.
The stakes are colossal. We are talking about a combined market of over 780 million consumers and a bilateral trade in goods that already exceeded €88 billion in 2022. The objective of the iTA is to dismantle tariff and non-tariff barriers, simplify procedures, and stimulate investment. But between the signing of an agreement and its effective implementation on the ground, there is a world of logistical, customs, and regulatory complexities. These first 48 hours offer us a valuable first lesson on the reality of large-scale trade integration.
From the early hours of May 1, the question on the lips of all importers and exporters was: which tariff reductions apply immediately? The agreement provides for a gradual dismantling of customs duties over several years, but a significant first tranche has come into force. Our initial analyses of customs declarations confirm the expected reductions on several key products.

However, not everything has been smooth. Reports indicate confusion over some specific products, particularly processed agricultural products. For example, for certain cheeses (HS code 0406), the precise classification to benefit from the preferential tariff required clarification from the customs authorities, leading to delays for the first shipments.
The promise of simplified customs procedures was at the heart of the iTA. The first 48 hours have shown a mixed picture. In major ports like Rotterdam, Antwerp, and Santos, the IT systems seem to have integrated the new rules well. Advance declarations and the Authorized Economic Operator (AEO) status have allowed many large groups to clear their goods without any notable hitches.
However, challenges quickly emerged. The main point of friction has been the management of the EUR.1 movement certificate, a key document to prove the preferential origin of goods. Several companies, especially less prepared SMEs, had their goods blocked due to formal errors in filling out these certificates. It is estimated that about 15% of the first declarations requesting the benefit of the iTA were temporarily suspended for documentary reasons. In addition, unexpected delays were reported at secondary entry points, which are less accustomed to handling such large trade flows and whose customs staff were not yet fully trained in the subtleties of the new agreement.
A Brazilian importer of auto parts told us yesterday: "We have been waiting for this tariff reduction for years, but our first container is stuck in Itajaí because the HS code mentioned on the origin certificate allegedly does not exactly match that of our declaration. It's an immense frustration."
The reception of the agreement by the business world is mostly positive, but tinged with great caution. The major industrial federations, such as the VDA in Germany for the automotive industry or the CNI in Brazil, have hailed a "historic step". The logistics directors and sales managers contacted over the past 48 hours express relief, but emphasize the uncertainty that remains.
It is obviously too early to have consolidated statistics, but real-time data from logistics platforms already show trends. An increase of about 10% in the volume of sea freight bookings from Europe to MERCOSUR was observed in the week preceding May 1, a sign of clear anticipation by companies. The flows of agri-food products (wines, cheeses, olive oil) and capital goods were the first to react.
The main challenges at the borders, besides documentary issues, have been logistical. The sudden increase in volumes on certain lines has put a strain on storage capacities in ports and airports. Longer than usual truck queues have been observed at land border posts between Brazil and Argentina, where the customs systems of both countries must now interface with the new requirements of the iTA.
These first 48 hours, although short, are rich in lessons for companies in both blocs:
The application of the iTA is a marathon, not a sprint. These first days have highlighted the immense opportunities but also the frictions inherent in a change of such magnitude. In the coming weeks, we will analyze in more detail the sectoral impacts and the strategies that companies will have to adopt to successfully navigate this new commercial environment.
