Genetically Modified Corn NK603 × T25: The EU Renews Its Authorization and What Importers and Manufacturers Must Do

Key data

Corn importers and food and feed manufacturers working with the genetically modified variety NK603 × T25 have the green light to continue operating in the European Union. Implementing Decision (EU) 2026/1417, adopted on 29 June 2026 and published in the Official Journal on 3 July 2026, formally renews the marketing authorization for this variety under Regulation (EC) No 1829/2003.

The renewal is neither automatic nor indefinite: authorization holders and all operators in the supply chain must comply with the established conditions. Any breach in labeling, traceability or post-market surveillance may result in suspension or revocation of the authorization.

What does this regulation establish?

Corn NK603 × T25 is a genetically modified corn variety that combines two distinct biotechnological characteristics:

Implementing Decision 2026/1417 renews the authorization so that products that contain, are composed of or have been produced from this corn may continue to be imported, processed and commercialized in the EU. The legal basis is Regulation (EC) No 1829/2003, which regulates genetically modified food and feed in the European market.

The renewal implies that operators must comply with three blocks of obligations:

• Labeling: products must clearly identify the presence of genetically modified material in accordance with current European regulations.
• Traceability: operators must be able to trace the origin and destination of corn NK603 × T25 throughout the entire supply chain.
• Post-market surveillance: authorization holders are obliged to conduct continuous monitoring of the product's effects once on the market and to report results to the competent authorities.

Economic and operational impact

For operators already working with this variety, the renewal means operational continuity without the need to reformulate products or seek alternative raw materials. Interruption of authorization would have forced product withdrawal from the market and renegotiation of supply contracts, with potentially significant costs.

However, the renewal does not eliminate operational burdens: traceability and labeling systems must be active and auditable at all times. Companies that have not updated their internal procedures since the previous authorization must review whether they continue to comply with current requirements of Regulation (EC) No 1829/2003.

The main operational impacts are:

• Importers: may continue imports of corn NK603 × T25 without additional restrictions, but must ensure traceability documentation for each batch.
• Processed food manufacturers: products containing or produced from this corn must maintain labeling in accordance with GMO regulations.
• Feed producers: the authorization also covers use in feed, so they may continue incorporating this variety in their formulations under the same traceability and labeling obligations.

Who does it affect?

• Corn importers bringing batches of NK603 × T25 from third countries (mainly North and South America).
• Processed food manufacturers using corn or corn derivatives (starch, flour, oil, glucose syrup) in their formulations that may contain this genetically modified variety.
• Feed producers incorporating corn NK603 × T25 as raw material in their mixtures or compound feeds.
• Authorization holders, who are directly responsible to the European Commission for compliance with renewal conditions, including post-market surveillance.
• Intermediate operators (warehouses, distributors, traders) handling this corn in the supply chain and subject to traceability obligations.

Practical example

A Spanish compound feed manufacturer for pig farming imports corn from Argentina, part of which corresponds to the NK603 × T25 genetically modified variety. Thanks to the renewal of authorization through Decision 2026/1417, it can continue using this raw material without interruptions in its production process.

However, to comply with the renewal conditions, the company must:

• Have documentation proving the traceability of each batch of corn NK603 × T25 from origin to its incorporation into the feed.
• Ensure that the labeling of its feeds correctly reflects the presence of genetically modified material, in accordance with Regulation (EC) No 1829/2003.
• Collaborate with the authorization holder if it requires data for the post-market surveillance report.

If the company does not maintain these systems updated and an inspection occurs, it could face corrective measures or, in serious cases, suspension of its ability to operate with this variety in the European market.

What should companies do now?

1. Verify if they work with corn NK603 × T25: review technical data sheets and origin certificates of raw materials to confirm whether any batch corresponds to this genetically modified variety.
2. Audit traceability systems: check that records of entry, transformation and exit of corn NK603 × T25 are complete and auditable by competent authorities.
3. Review product labeling: ensure that all products containing or produced from this corn comply with GMO labeling requirements established in Regulation (EC) No 1829/2003.
4. Contact the authorization holder: if the company is an operator in the supply chain, coordinate with the holder to learn about specific requirements of the post-market surveillance plan.
5. Update internal procedures: if traceability and labeling protocols have not been reviewed recently, now is the time to update them to ensure continued compliance with the renewed regulation.
