CLP and GHS

The CLP Regulation decides how substances and mixtures are classified, labelled and packaged in the EU. Its classification is the basis of section 2 of every safety data sheet. What it covers, how it relates to the UN GHS and which changes are under way.

What CLP is

The Globally Harmonised System (GHS) is a set of UN recommendations for classifying chemicals and communicating their hazards through labels and safety data sheets. It is not binding on its own: each country decides how to adopt it.

In the EU, the GHS was adopted through Regulation (EC) No 1272/2008 (CLP). Suppliers have to classify substances and mixtures before placing them on the market, label and package them accordingly, and use the same classification in section 2 of the safety data sheet. The SDS itself is governed by REACH, the label by CLP.

Three groups of hazards

Annex I to CLP sets the criteria for each hazard class. They fall into three main groups:

Annex I, Part 2

Physical hazards

For example explosives, flammable gases, liquids and solids, oxidisers, gases under pressure and substances corrosive to metals.
Annex I, Part 3

Health hazards

For example acute toxicity, skin corrosion and irritation, sensitisation, carcinogenicity, mutagenicity, reproductive toxicity and specific target organ toxicity.
Annex I, Part 4

Environmental hazards

Hazards to the aquatic environment and, since Regulation (EU) 2023/707, new classes for endocrine disruptors and persistent substances (PBT, vPvB, PMT, vPvM).

What goes on the label

A hazardous substance or mixture carries a label with these elements, in the official language of the country where it is sold.

Source: CLP, Art. 17
  • Name, address and telephone number of the supplier
  • Nominal quantity, for packages made available to the general public
  • Product identifiers
  • Hazard pictograms, where applicable
  • Signal word – “Danger” or “Warning”
  • Hazard statements (H statements)
  • Precautionary statements (P statements)
  • Supplemental information, where applicable

Changes to CLP

Three recent acts change how products are classified and labelled. Dates differ for substances, mixtures and products already on the market.

Delegated Reg. (EU) 2023/707

New hazard classes

Endocrine disruptors, PBT/vPvB and PMT/vPvM. Substances from 1 May 2025 (until 1 November 2026 for those already on the market), mixtures from 1 May 2026 (until 1 May 2028 for those already on the market).
Regulation (EU) 2024/2865

Revision of CLP

Specific rules on label formatting, relabelling deadlines after a change in classification, advertisements, distance sales and labelling at filling stations. In force since 10 December 2024, applied in stages.
Regulation (EU) 2025/2439

Deferral to 2028

Defers the new rules on label formatting, advertisements, distance sales offers and relabelling. Several of them now apply from 1 January 2028.

Classification changed?

A new classification means the SDS has to be updated without delay. We reclassify your mixtures under the current CLP and revise the safety data sheets.
