Date Adopted: 26 November 2025
Published: Official Journal of the European Union, L 2439 (3 December 2025)
Status: Adopted by the European Parliament and the Council
Overview
The European Union has adopted Regulation (EU) 2025/2439, introducing revised application dates and transitional provisions for recent changes to EU chemical labelling laws. The Regulation amends Regulation (EU) 2024/2865, which updated the EU’s core Classification, Labelling and Packaging (CLP) Regulation (EC) No 1272/2008.
The update primarily postpones the implementation of several new compliance requirements, allowing businesses additional time to adapt.
Background
The CLP Regulation forms the foundation of EU chemical safety, defining how substances and mixtures must be classified and labelled to protect human health and the environment.
In 2024, Regulation (EU) 2024/2865 introduced significant changes, including:
- New chemical label formatting requirements
- Revised deadlines for relabelling following classification changes
- Expanded information obligations for advertisements and distance sales
- Specific labelling rules for chemicals sold at filling stations
Due to the scale and operational impact of these changes, EU institutions reassessed the original implementation schedule.
Timeline Changes
Regulation (EU) 2025/2439 defers several obligations introduced under Regulation 2024/2865:
- Labelling, formatting, and advertising requirements will now apply from 1 July 2026
- Certain specific and transitional provisions will apply from 1 January 2027 or 1 January 2028, depending on the requirement
This phased approach is intended to support smoother implementation across industries.
Transitional Provisions
To prevent regulatory uncertainty:
- Companies may continue using existing classification and packaging rules until the new deadlines
- Transitional measures ensure legal clarity while the updated framework is gradually implemented
Why This Matters
- Improved preparedness: Companies gain additional time to update labels, systems, and compliance processes
- Regulatory stability: Phased deadlines reduce the risk of market disruption and supply chain challenges
- Continued protection: The core objectives of the CLP Regulation—health and Environmental Protection remain unchanged
Status & Next Steps
The Regulation will enter into force 20 days after publication in the Official Journal and is directly applicable across all EU Member States.
Businesses affected by CLP requirements should review the revised timelines and align internal compliance strategies accordingly.
