Rules of origin under the EU–Mercosur agreement
The lower duties in the EU–Mercosur agreement aren't available to every product that ships from Santos to Rotterdam or from Hamburg to Buenos Aires. They're for goods that originate in the EU or in Mercosur. Rules of origin are the test for that.
Why the rules exist
Without them, a product made anywhere could be routed through a Mercosur or EU country and enter at the preferential rate. Rules of origin stop that. They set out how much of the work, or which steps of production, have to happen inside the two blocs for a product to count as theirs.
The two basic ways a product qualifies
Preferential rules of origin in EU agreements work along two lines.
Wholly obtained. Some products come entirely from one party: cattle born and raised in Uruguay, soybeans grown in Paraguay, iron ore mined in Brazil. These originate without further conditions.
Sufficiently processed. Most manufactured goods contain materials from elsewhere. They originate if the work done in the EU or Mercosur meets the rule written for their product. Those product-specific rules are listed by HS chapter or heading in the agreement. A rule can require a change of tariff classification, a maximum share of non-originating materials, a specific processing step, or a combination.
Simply passing goods through, repacking them or doing other minor operations doesn't make them originate.
Claiming the preference
Meeting the rule isn't enough on its own. The importer has to claim the preferential rate when the goods are declared, backed by proof of origin in the form the agreement requires, and the exporter has to be able to show how the product qualifies if customs asks. Keep supplier declarations and production records for that.
We don't summarise the procedural details (who can issue proof of origin, in what form, and any value thresholds) because we haven't checked them line by line against the agreement text. Use the official sources below.
What this means for the calculator
The calculator doesn't check origin. Every rate and saving it shows assumes your goods qualify as originating and that you claim the preference. If they don't, the normal duty applies, which the calculator also shows as today's applied rate. The methodology page lists this and the calculator's other limits.
Where to check the rules for your product
- Agreement text, OJ L 2026/184: the origin rules and the product-specific rules are part of the agreement.
- European Commission, DG TAXUD: Mercosur: the EU customs page on the agreement.
- Access2Markets: rules of origin: the Commission's guide to preferential origin.
For a binding answer on a specific product, ask the customs authority of the importing country. Our post rules of origin in plain terms walks through a few examples.
