EU–Mercosur rules of origin in plain terms

A bottle of French wine shipped to São Paulo pays 27% duty today. Under the EU–Mercosur agreement it paid 24% from 1 May 2026, and it'll pay nothing from 2034. But the lower rate only applies if the wine counts as made in the EU. That's what rules of origin decide, and they're easy to overlook until a customs officer asks about them.

What "originating" means

The agreement gives its preferences to goods that originate in the EU or in Mercosur, not to anything that happens to ship from a European or South American port. A product can originate in one of two broad ways.

It can be wholly obtained in one of the parties. Cattle born and raised in Uruguay, slaughtered there and shipped as boneless beef (0201 30 00) is the textbook case. Nothing in it came from outside, so there's nothing to prove beyond where it came from.

Or it can be sufficiently processed. Most manufactured goods contain some imported material, and that's fine as long as the work done inside the EU or Mercosur meets the rule the agreement sets for that product. These product-specific rules are listed by HS chapter and heading. Depending on the product, a rule might require that the finished good falls under a different tariff heading from its imported inputs, that non-originating materials stay below a certain share of the price, or that a particular processing step takes place locally.

What doesn't work is shortcuts. Shipping goods through an EU or Mercosur country, relabelling them or repacking them doesn't make them originate.

Three examples

Wine into Brazil. French wine made from grapes grown in France is straightforward. If you blend in wine from outside the EU, check the rule for heading 2204 before claiming the preference. The stakes are easy to see: on a shipment worth EUR 50,000 (an example value), the duty in 2026 is EUR 12,000 at the preferential 24% against EUR 13,500 at the normal 27%. The gap widens every January until the preferential duty reaches zero in 2034.

Beef into the EU. Origin is rarely the sticking point here. The quota is. Mercosur beef only gets a preference inside the BF1 and BF2 quotas, at 7.5% instead of 12.8% plus about EUR 300 per 100 kg. The beef has to originate and the importer needs a quota licence. Our beef guide has the numbers.

A car into Brazil. A car assembled in Germany will almost certainly contain parts made outside the EU. Whether it originates depends on the product-specific rule for chapter 87, so read that rule in the agreement. It matters a lot. Cars under NCM 8703.23.10 face Brazil's full 35% until the end of 2032, and the only way to pay less before then is the 15V quota at 17.5%, which is open to originating cars only.

Claiming it

Meeting the rule doesn't lower the duty by itself. The importer has to claim the preferential rate in the customs declaration, supported by proof of origin in the form the agreement sets out. The exporter, in turn, has to be able to back up that claim if customs checks later, so keep supplier declarations, bills of materials and production records.

We haven't summarised the procedural rules (who issues proof of origin, in what format, any value thresholds) because we haven't checked them against the agreement text line by line. The official sources are below.

Where to look

Start with the rules of origin page on this site, which links to the agreement text in the EU's Official Journal (OJ L 2026/184), the European Commission's customs page on Mercosur and the Access2Markets guide. For a binding answer on a specific product, ask the customs authority of the importing country.

The calculator assumes your goods qualify and shows both the preferential and the normal duty, so you can see what's at stake before you do the origin work. The FAQ covers a few related questions.
