What must be on a CLP compliant label?

Since there are quite a few rules for labelling hazardous chemicals, it will be easiest to look at the correct labelling on an example. Below you can see the label of a dangerous chemical intended for sale to general users.

The obligatory parts of the CLP label are:

- product identifiers (trade name and/or designation of the mixture),

- identity of the supplier,

- signal word,

- hazard statements,

- precautionary statements,

- obligatory supplemental information (Regulation (EC) No 648/2004 on detergents),

- UFI code.


As the product is supplied to the general public, its nominal quantity is also provided on the label.


During the inspection, the inspector usually first checks the suitability of the CLP labels and safety data sheets.

When labelling chemicals, it is necessary to pay attention to several rules that we have covered in our BLOG posts.

Below is an example of rules for the size and shape of CLP pictograms.

The colour and appearance of the label must allow the hazard pictograms and their background to be clearly visible.

The pictograms must be in the form of a square placed at a point, ie. they must be shown in diamond shape when the label is read HORIZONTALLY.

They must also have a black symbol with a red frame on a white background.

The smallest dimensions refer to the sides of the red frame of the pictogram itself.

What is a UFI and what it means?

You can read more about the UFI code as part of the provision of our UFI code editing services and on our BLOG.

What does it mean to be REACH compliant?

If your product is a chemical product (substance or mixture), you need to ensure that every substance in it has been registered under EU REACH when the volume of that substance exceeds 1t/y. The best way to show compliance is to obtain a REACH registration number issued by the European Chemicals Agency (ECHA).

Is my product a biocide?

A biocidal product is defined as a product with an active substance that is intended to destroy, render harmless, deter, prevent the action of, or otherwise exert a controlling effect on harmful or undesired organisms. 

Since September 2013, the Biocidal Products Regulation (BPR, Regulation (EU) 528/2012) acts as a legal framework with the aim to control and harmonize the rules delimiting the marketing and use of biocidal products in the European Union. 

It is very important to emphasize that the sale of a biocidal product is not allowed without properly regulated documentation (biocidal product registration) and the use of a certified manufacturer / supplier of the active substance (Article 95 list).

Especially in the initial steps of selling chemicals, all entrepreneurs have a lot of questions: "What must be on a CLP compliant label? What is a UFI and what it means? What does it mean to be REACH compliant? Is my product a biocide?«
