European Council Approves “Stop-the-Clock” Mechanism on CLP Regulation

On 24 September 2025, the European Council approved the introduction of a “stop-the-clock” mechanism for the revised Classification, Labelling and Packaging (CLP) Regulation. The measure, part of the Commission’s Omnibus VI simplification package, delays the entry into application of the new rules to 1 January 2028.

Purpose: Legal Certainty and Simplification

The mechanism is designed to provide legal certainty for businesses and to avoid a fragmented regulatory framework. Without the postponement, different provisions of the revised CLP would have applied on different dates, creating additional compliance challenges for companies.

The alignment of deadlines covers obligations on:

• Relabelling of substances and mixtures
• Formatting requirements for labels
• Advertisements and distance sales
• Labelling at fuel pumps

By postponing these obligations, the European Council aims to give companies, particularly SMEs, more time to adapt to the new requirements while ensuring continued protection of health and the environment.

Background: Original Deadlines

The revised CLP Regulation entered into force on 10 December 2024, with the majority of obligations initially scheduled to apply from 1 July 2026, and some provisions from 2027 (see more details here). The “stop-the-clock” mechanism shifts all these dates to 1 January 2028, creating a single, harmonised starting point for compliance.

Next Steps in the Legislative Process

Following the European Council’s approval, negotiations will continue with the European Parliament to finalise the regulation. The measure forms part of the broader Omnibus VI package, which seeks to simplify EU chemicals legislation while maintaining high levels of health and environmental protection.
