One of the most technical yet crucial aspects of the EU-MERCOSUR trade agreement is its protocol on rules of origin. These rules are the mechanism that determines whether a product can be considered "originating" from the EU or MERCOSUR and thus benefit from the preferential tariffs provided by the agreement. For businesses, a misunderstanding or misapplication of these rules can wipe out all expected tariff benefits. Mastering this regulatory "labyrinth" is therefore essential to fully capitalize on the agreement.
This article breaks down the fundamental principles of the agreement's rules of origin, explains the concepts of "wholly obtained" products and "substantial transformation," and provides a practical guide on how to document and prove the origin of your products.
Rules of origin exist for a simple reason: to prevent trade deflection. Without them, a third country could simply route its products through a member country of the agreement to unduly benefit from preferential tariffs, without any significant value being added there. Rules of origin ensure that only products with a real economic link to the parties of the agreement benefit from its advantages.

In the context of the EU-MERCOSUR agreement, this means that a product can only be classified as "originating" if it has been either wholly produced or sufficiently transformed in one of the two regions.
The simplest concept is that of "wholly obtained" products. It applies to goods that are naturally derived or entirely manufactured in one of the parties. The list is quite intuitive and includes:
* Mineral products extracted from the soil or subsoil. * Harvested plant products. * Live animals born and raised there. * Products from live animals (milk, eggs, etc.). * Products of hunting and fishing. * Products of sea fishing taken from international waters by vessels registered in a party and flying its flag. * Goods manufactured exclusively from these products.
For these products, determining the origin is relatively straightforward.
The situation becomes more complicated for manufactured products that incorporate materials or components from third countries (non-originating). For these products to be considered originating, they must undergo a "substantial transformation" in the EU or MERCOSUR. The agreement defines three main criteria to determine if a transformation is sufficient. These criteria are specific to each product and are detailed in the annex on product-specific rules of origin (PSRs).
The three criteria are:
The agreement provides for flexibilities to help companies meet the origin requirements.
* The tolerance rule (or *de minimis*): It allows the use of a small amount of non-originating materials even if the change in tariff classification rule is not met. Generally, this tolerance is set at 10% of the ex-works price of the product.
* Cumulation: This is a fundamental concept. Bilateral cumulation allows materials originating from the other party (e.g., MERCOSUR components used in an EU factory) to be considered as originating from the party where the manufacturing takes place. This encourages the integration of value chains between the two blocs. A European car manufacturer can thus use Brazilian car parts without them being considered "non-originating," thus facilitating compliance with the origin rule for the finished car.
Once a company has determined that its product is originating, it must prove it to the customs authorities. The EU-MERCOSUR agreement modernizes this process by relying on a Statement on Origin issued by the exporter themselves. This system replaces the old certificates of origin (like the EUR.1) that had to be stamped by customs authorities.
The Statement on Origin can be placed on the invoice or any other commercial document that clearly identifies the products. The exporter must be registered in the EU's Registered Exporter system (REX) to be authorized to issue such statements for shipments exceeding a certain value (usually €6,000).
The exporter who issues a Statement on Origin must be prepared to prove the origin of their products at any time. It is therefore imperative to keep all supporting documents for several years (usually 3 to 5 years), including:
* Accounting documents related to manufacturing. * Supplier declarations regarding the origin of the materials used. * Technical data sheets and product bills of materials.
| Key Concept | Description | Practical Example | | :--- | :--- | :--- | | Wholly Obtained | Products that are natural or made from 100% local materials. | Wine produced in Argentina from Argentine grapes. | | Substantial Transformation | Sufficient transformation of non-originating materials. | Manufacturing of furniture (HS 9403) in Spain from wood imported from Russia (HS 4407). | | Bilateral Cumulation | Materials from one party are considered as originating from the other. | A German car manufacturer uses Brazilian engines for its cars exported to Paraguay. | | Statement on Origin | Self-certification of origin by the registered exporter (REX). | The exporter adds a standard sentence on the commercial invoice. |
The rules of origin in the EU-MERCOSUR agreement are complex, but they are the key that unlocks the door to the agreement's tariff benefits. For businesses, investing time and resources to understand and correctly apply these rules is not a burden, but a strategic investment. Rigorous origin management not only reduces costs but also optimizes supply chains by taking advantage of bilateral cumulation. The companies that master this regulatory labyrinth will be the ones that thrive the most in this new transatlantic trade space.
