What is the revision of the CLP Regulation?
The revision of the CLP Regulation welcomes an agreement on improving the classification, labelling and packaging of hazardous chemical substances reached in 2023.
This agreement is formally set out in Regulation (EU) 2024/2865, published on 20 November 2024, with entry into force on 10 December 2024, which amends the CLP Regulation (EC) No 1272/2008. The consolidated version of the CLP dates from 23 December 2025.
The new measures will provide better protection for consumers, workers and the environment. At the same time, they will improve communication on hazardous chemicals sold online and speed up the identification of hazardous substances and mixtures across the EU. They will also provide more flexibility on how labels can be used.
According to the European Commission, the following points describe the improvements brought by the revision of the CLP Regulation.
Improvements introduced by the CLP revision
- Updated rules for classifying complex substances (substances containing more than one constituent, known as “MOCS”). Plant extracts and essential oils have a specific exemption subject to a five-year review of the scientific evidence.
- Greater protection for consumers buying hazardous chemicals online. Websites must state the hazardous properties of the products.
- Clearer labelling of hazardous chemical products, including in online sales.
- Fold-out and digital labelling: companies will be able to use them, while important safety information and hazard pictograms will still have to appear on the packaging.
- New classification proposals: in addition to Member States and industry, the Commission will also have the right to draw up classification proposals for potentially hazardous substances, which will speed up the pace of identifying hazardous substances.
- Refillable chemical products: for the first time, rules are established to support the safe sale of bulk household chemicals, thereby reducing packaging and the resulting waste.
- Better information for poison centres, which will receive faster, more accurate data for medical emergencies.
These measures are being adopted with the aim of moving towards a more sustainable chemical industry. This revision is intended to serve as an example for chemical companies worldwide and to contribute to the “Strategy for the Sustainability of the Chemical Industry”, a key part of the European Green Deal.
New CLP hazard classes
This amendment to the CLP Regulation, whose new classes and criteria were introduced through Delegated Regulation (EU) 2023/707, in force since 20 April 2023, establishes new hazard classes and new criteria for the classification, labelling and packaging of substances and mixtures placed on the EU market under REACH.
It also applies to active substances in biocides and plant protection products. These are the new hazard classes:
- ED HH, categories 1 and 2 (endocrine disruptor for human health)
- ED ENV, categories 1 and 2 (endocrine disruptor for the environment)
- PBT (persistent, bioaccumulative and toxic) and vPvB (very persistent, very bioaccumulative)
- PMT (persistent, mobile and toxic) and vPvM (very persistent, very mobile)
Once all the agreed changes to the Regulation have been adopted, together with the new hazard criteria for endocrine disruptors and persistent, toxic chemicals in the environment, better communication and identification of chemical hazards will be guaranteed.
CLP compliance deadlines (status as of September 2026)
The new rules entered into force on 20 April 2023. During the transitional period, substances and mixtures may be classified on a voluntary basis.
| Product type | Deadline | Status |
|---|---|---|
| New substances on the market | 1 May 2025 | Already in force |
| New mixtures on the market | 1 May 2026 | Already in force |
| Substances already on the market | 1 November 2026 | Upcoming deadline |
| Mixtures already on the market | 1 May 2028 | Pending |
For new substances placed on the market, companies have had to comply with the rules since 1 May 2025; substances already on the market have until 1 November 2026. For mixtures, there are different transition periods: the new hazard classes apply from 1 May 2026 for new mixtures, and for mixtures already on the market, companies have until 1 May 2028 to update classification and labelling.
What this means for your company
- Check whether your products contain substances in the new categories (ED, PBT, PMT).
- Update pictograms, hazard statements and safety data sheets (SDS).
- Communicate the changes throughout the supply chain.
