Key takeaway
What This Development Means
The EU’s draft regulation on data requirements for active substances represents a significant modernisation of plant protection policy. It demands deeper toxicological, ecological, and efficacy data while offering transitional flexibility. Industry stakeholders must act swiftly to ensure compliance and maintain market access.
What is the key change in the updated EU data requirements for active substances?
The update mandates more comprehensive and standardised data on toxicity, environmental fate, and endocrine disruption. It also distinguishes requirements for chemical versus biological substances, including new protocols aligned with EFSA and ECHA guidance.
How will the transition period affect ongoing applications?
Applicants have a 24-month window to choose between the existing and new requirements. This decision must be declared at submission and is binding for that application. It provides time for industry to adjust without immediate regulatory disruption.
The European Commission has published a draft regulation updating data requirements for the approval of active substances in plant protection products. The revision, which amends Commission Regulation (EU) No 283/2013, aims to align regulatory practices with scientific advancements and emerging environmental and public health priorities. The public feedback period is open until 2 October 2025.
Strengthened Safety Standards For Active Substances
The draft regulation introduces significant changes to the types of information required for chemical and biological active substances seeking EU approval. These updates reflect enhanced methodologies for risk assessment and data evaluation, with a strong emphasis on protecting human health, vulnerable groups, animals, and the environment.
Applicants will now need to provide more comprehensive data, including:
- All available toxicological and ecotoxicological studies, including non-target species effects and long-term environmental impact.
- Information on relevant metabolites, breakdown products, and potential groundwater contamination.
- Summaries of peer-reviewed scientific literature.
- Comparative assessments for active substances also used in veterinary or biocidal products.
- Expanded testing protocols for endocrine-disrupting properties, neurotoxicity, and developmental toxicity.
Revised Approach For Biologicals And Micro-Organisms
Reflecting a growing market interest in biopesticides, the regulation clearly differentiates data expectations between chemical and biological active substances. A separate dossier structure (Part B) applies for micro-organisms, including metabolites claimed to contribute to plant protection effects. This distinction supports tailored assessments based on substance type and function.
Transition Period And Compliance Strategy
To ease the burden of immediate compliance, the Commission is offering a transitional period of 24 months. During this time, applicants may submit data using either the existing or updated requirements, provided the decision is clearly stated at the time of application and remains fixed for the procedure.
Importantly, plant protection product authorisation applications may also use legacy data requirements if they relate to active substances approved or renewed under the previous rules. This flexibility acknowledges varying levels of readiness across the industry.
Implications Across The Agricultural Supply Chain
This regulatory update carries wide-reaching implications for chemical manufacturers, formulators, food producers, environmental scientists, and policymakers. Stakeholders will need to:
- Reassess existing dossiers and pipeline substances for compliance gaps.
- Prepare to invest in additional studies, particularly those addressing newer endpoints like endocrine disruption and environmental persistence.
- Anticipate extended review times due to expanded data packages.
- Monitor further updates from EFSA and ECHA guidance linked to the new rules.
New Testing Protocols And Environmental Focus
The regulation incorporates EFSA’s latest guidance on risk assessments for birds, mammals, and bees, as well as new protocols concerning water treatment and residues. This underscores a shift towards holistic ecosystem protection and drinking water safety.
Industry Response And Call For Feedback
Stakeholders have until 2 October 2025 to submit feedback on the proposed changes via the Commission’s “Have Your Say” portal. Contributions will inform the final version of the regulation, which is expected to be adopted shortly thereafter.
