EU Set to Debate ‘One Substance, One Assessment’ Chemicals Package to Overhaul Safety Rules
MEPs to debate 'one substance, one assessment' rule to simplify EU chemical safety laws. Industry must prepare for regulatory change.


The European Commission’s 2025 Work Programme includes plans to introduce a chemicals industry package in Q4 2025, aiming to streamline compliance, reduce regulatory burdens, and enhance data management. The upcoming proposal is expected to impact manufacturers, suppliers, and businesses handling hazardous substances. A targeted revision of REACH will also be included to improve regulatory efficiency while maintaining high safety and environmental standards.
While full details are yet to be released, the Commission’s plans focus on:
If implemented as planned, businesses can expect reduced administrative complexity, particularly in chemical registration, reporting, and authorisation. This is expected to ease costs for manufacturers and service providers in the supply chain.
Despite the focus on simplification, companies handling PFAS and other high-risk substances will likely face stricter classification and authorisation processes, ensuring compliance with the Chemicals Strategy for Sustainability.
A new EU-wide data platform is expected to improve regulatory monitoring and supply chain transparency, making compliance more efficient and ensuring better industry oversight.
Industry leaders have responded positively to the proposed regulatory simplifications, while environmental groups stress the importance of maintaining strong safety measures.
Maroš Šefčovič, Commissioner for Trade and Economic Security, emphasised:
"We have listened to and heard our businesses’ call for rules that are simpler to manage."
The proposal is expected to undergo stakeholder consultations before being formally introduced in Q4 2025.
