New phytosanitary labeling 2026: what manufacturers and distributors must change

Key data

Manufacturers and distributors of phytosanitary products and pesticides face a new and immediate obligation: their labels no longer comply with current regulations. The Regulation (EU) 2026/1123, published on May 27, 2026 and in force since May 26, 2026, replaces the previous Regulation (EU) No 547/2011 and imposes harmonized labeling requirements throughout the European Union. This is not a minor format change: it affects the mandatory content of labels, packaging processes and associated technical documentation.

The stated objective of the regulation is threefold: to improve product traceability, strengthen the safety of professional users and protect the environment through clearer and more complete information. For companies in the sector, this translates into a comprehensive review of their labeling materials.

What does this regulation establish?

Regulation (EU) 2026/1123 establishes harmonized labeling requirements for all phytosanitary products marketed in the EU. These are the elements that new labels must include or update:

The regulation expressly repeals Regulation (EU) No 547/2011, which has been the reference framework for phytosanitary labeling until now. Companies that maintain labels based on the previous regulation will be in non-compliance from the date of entry into force.

Economic and operational impact

The impact is not just documentary. Adapting labeling involves real costs in several dimensions:

• Label redesign: Each product reference marketed requires a review and update of its label in accordance with new requirements.
• Packaging reformulation: In many cases, changes in the mandatory label content require modifying the physical design of the container or packaging material.
• Technical documentation review: The technical documentation associated with each product must be updated to reflect new information standards.
• Risk of market withdrawal: Products that do not comply with new labeling may be withdrawn from the market by the competent authorities.
• Administrative sanctions: Non-compliance may result in administrative sanctions, the amount of which will depend on the national legislation of each Member State.

The cost of adaptation varies significantly depending on the size of the product catalog and the degree of divergence between current labels and new requirements. Companies with a larger number of references on the market will have a proportionally greater adaptation burden.

Who does it affect?

• Manufacturers of phytosanitary products: Required to adapt the labels of all their products before marketing.
• Distributors of phytosanitary products: Must verify that the products they distribute comply with new labeling.
• Professional users of pesticides: Must ensure that the products they purchase and use carry labeling in accordance with Regulation (EU) 2026/1123.
• Agricultural sector operators: Any company or professional using phytosanitary products in their activity must be aware of new requirements to identify compliant products.
• Packaging and graphic design companies: Suppliers working with the phytosanitary sector must be aware of new standards to offer compliant solutions.

Practical example

A Spanish herbicide manufacturer with 15 product references on the European market has, since May 26, 2026, the obligation to review the labels of each and every one of those 15 references. For each one, it must verify that information on composition, instructions for use, safety warnings and environmental data complies with the new harmonized standards of Regulation (EU) 2026/1123, replacing any reference to the previous Regulation (EU) No 547/2011.

If during a market inspection the authorities detect that any of those references is still being marketed with the previous labeling, the company is exposed to administrative sanctions and product withdrawal from the market, with the resulting reputational and economic cost. Starting the adaptation now—beginning with the references with the highest sales volume—is the most efficient decision to minimize risk.

What should companies do now?

1. Audit the current catalog: Identify all phytosanitary product references marketed and review whether their labels comply with the new requirements of Regulation (EU) 2026/1123.
2. Prioritize by volume and risk: Begin adaptation with products with the highest sales volume or greatest exposure to market inspections.
3. Review the four blocks of mandatory content: Composition, instructions for use, safety warnings and environmental data must be adjusted to new harmonized standards.
4. Update technical documentation: All technical documentation associated with each product must reflect new labeling requirements.
5. Reformulate packaging if necessary: If changes in label content require modifying the physical design of the container, start the process with packaging suppliers as soon as possible.
6. Inform the distribution chain: Communicate labeling changes to distributors and professional customers to avoid confusion and ensure compliance throughout the chain.
7. Document the adaptation process: Keep a record of the adaptation process as evidence of due diligence in case of inspections.
