Mercosur-EU deal: Brazil hit a record, Argentina lost ground
In October, Brazilian exports to the European Union rose 32% and the country posted its largest October trade surplus in 37 years. Argentina, with access to the same tariff, fell 6.7%. The difference is not in the deal.
On 6 November 2026, Brazil’s MDIC and Secex released the October figures. Brazilian exports to the European Union reached USD 6.04 billion for the month, up 32% from USD 4.58 billion in October 2025. For January to October, the total is USD 49.64 billion, up 20%.
That result helped Brazil close October with a trade surplus of USD 9.32 billion, 39.4% above the previous year. It is the largest surplus for any October since the series began in 1989. Thirty-seven years.
Looking at Europe as a bloc, sales reached USD 7.76 billion, up 35.8%, driven mainly by food.
Same deal, opposite results
In the same month, Argentina went the other way. Argentine exports to the European Union fell 6.7% in October, totalling USD 1.53 billion. For the year so far, the drop is 17.2%, at USD 13.115 billion.
Brazil and Argentina are partners in the same agreement. So are Paraguay and Uruguay. All four have access to exactly the same preferential tariff, under the same text, since the deal took provisional effect on 1 May 2026.
So where is the difference?
Not in the deal. In the process.
Capturing a preferential tariff is not automatic. It depends on three things that happen before the cargo leaves:
- The correct tariff classification. The HS code defines which tariff applies. A wrong code cancels the preference, even with the deal in force.
- A certificate of origin that meets the rule. Zero tariff applies to goods that prove Mercosur origin, in the format Europe accepts. Without that proof, you pay the full rate.
- Logistics adjusted to the new flow. More volume means more containers, more documents and more points where an operation can stall.
Companies that sorted these three out are selling more. Those that did not have the same agreement on paper and never see it on the invoice.
What this means for exporters
The deal opened the door, but it does not push anyone through. The tariff advantage is the same for every competitor in the bloc, which means it stops being an advantage and becomes the baseline.
From here, the competitive difference is the quality of your export process. That is what separates a 37-year record from a 17% decline.
If your company exports to Europe, or plans to, it is worth reviewing tariff classification and origin documentation before the next shipment. Fixing it at the office costs less than fixing it at the port.
