CLP labels are the primary carrier of information about chemical hazards on the packaging of substances and chemical mixtures. Proper labelling not only meets legal requirements but also ensures the safety of users and workers. It also allows for the continuous and uninterrupted placement of the chemical product on the market. In this article, we discuss which elements must appear on a chemical product label in accordance with Article 17 of the CLP Regulation (1272/2008/EC).

What is CLP labelling?

CLP labelling is a set of mandatory information that must be included on the label of a chemical product classified as hazardous (regardless of whether it is a substance or a mixture). The obligations in this area are defined in Regulation (EC) No 1272/2008 of the European Parliament and of the Council on classification, labelling and packaging of substances and mixtures (CLP). Of course, not all chemical products are subject to this regulation – for example, medicinal products or cosmetics are excluded – and therefore you will not find CLP labelling on their packaging.

Mandatory elements of the CLP label (according to Article 17 CLP)

According to Article 17 of the CLP Regulation, each CLP label must include the following elements:

1. Name of the supplier

The label must include:

• company name,

• address,

• telephone number.

2. Product identifier

It must clearly identify the substance or mixture:

• for substances: at least one of the chemical names in accordance with Annex VI or, if not available, other internationally recognised chemical names;

• for mixtures: the trade name of the mixture and information on the hazardous components.

3. Nominal quantity of the substance or mixture in the package

4. Pictograms

Graphical symbols specified in the CLP Regulation, shown as a diamond with a red border and white background. They indicate the type of hazard (e.g., corrosive, flammable, toxic).

5. Signal word

• “Danger” (for more severe hazards) or

• “Warning” (for less severe hazards).

6. Hazard statements (H-statements)

They describe the nature of hazards arising from the properties of the substance or mixture, e.g.:

• H225 – Highly flammable liquid and vapour

• H315 – Causes skin irritation

7. Precautionary statements (P-statements)

They inform about safe handling practices, e.g.:

• P210 – Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking.

• P280 – Wear protective gloves / protective clothing / eye protection / face protection.

8. Supplemental information

If applicable, additional elements required by other legislation may be needed (e.g., according to REACH or the Detergents Regulation). This also includes any required EUH statements.

9. UFI Code

Technically, this is also part of the supplemental information on the label, but due to its importance, it deserves a separate mention. The UFI code (Unique Formula Identifier) is assigned to a product according to the requirements of Annex VIII to the CLP Regulation and must appear on the label and in the related PCN (Poison Centre Notification) submission.

What to keep in mind regarding CLP labelling?

✅ Even the smallest package of a chemical product must have a legible label with all the required information – in some cases, exemptions may apply for very small packages.

✅ Label elements should be translated into all relevant languages.

✅ Missing any of the required elements may result in administrative penalties or a ban on placing the product on the market.

Example of a CLP label

Summary

Chemical product labels compliant with CLP are a legal obligation and a key element of effective chemical safety management. Proper labelling in line with Article 17 of the CLP Regulation is not only a matter of compliance, but also a practical measure to protect health and the environment. It also ensures uninterrupted and smooth circulation of the chemical product on the market.
