EUH401 — “To avoid risks to human health and the environment, comply with the instructions for use.”

Practical uses of EUH labelling

So now that we have become familiar with the EUH sentences, let us look at a few practical examples when they are used.  

A common situation: you are a supplier of cyanoacrylate adhesives. The presence of isocyanates means you have to label your products with EUH204 »Contains isocyanates. May produce an allergic reaction.«

A similar situation usually happens with epoxy resins. If they contain epoxy constituents with an average molecular weight ≤ 700, you should add the EUH205 “Contains epoxy constituents. May produce an allergic reaction.” on the labels of your products.

Another typical example of labelling with EUH sentences is chlorine-based cleaners. Suppose you sell them to the general public (consumers), and your product contains > 1 % of active chlorine. In that case, you should label your products with EUH206 “Warning! Do not use together with other products. May release dangerous gases (chlorine)”. This informs the consumer of the possible release of chlorine gas if they should use the product in combination with other household cleaners.

How to keep up with EUH labelling?

Keeping up with EUH labelling for hundreds or thousands of products can be a complex process.  

  1. You first must consider the type of your mixtures. 
  2. Secondly, check the CLP regulation in Annex II if your mixture is subject to EUH labelling. 
  3. Include the EUH sentence on your Safety Data Sheets in Section 2. 
  4. Include the EUH sentence on your product labels 
  5. Repeat this process for every product in your portfolio. 

Luckily, this time-consuming process has been made extremely straightforward with Chemius

Let us look at a cyanoacrylate glue example:

1. We add the substance and its concentration with the classification to the material composer. We can immediately see the proposed classification for the product and labelling with EUH sentence – in this case, EUH202.


2. If we then decide we do not want to have the product classified as hazardous and therefore lower the content of the substance from 15 % to %, we can immediately see the proposed labelling with EUH202 and EUH210.  

3.When creating the SDS, the Section 2.2 Label elements will look like this:

4. And the generated label will also contain the same label elements from the Safety Data Sheet.

In this way, we have successfully created the SDS and a corresponding label without thinking and checking CLP regulation, whether we have to add a EUH sentence to the label of our product.

EU chemicals’ regulation is one of the most complex chemical legislation. It follows GHS in general, yet also introduces many unique requirements and specifics.

With Chemius, managing labelling-related requirements has been taken to a new level. You are welcome to give it a try yourself for free at and see for yourself.  

We can also arrange an online practical presentation of Chemius for your company. You can write us at, and we will arrange a meeting.
