Diisocyanates Mandatory Training

Understand the mandatory training for PU-based products 


On August 4, 2020, a new restriction on diisocyantes was published in the Official Journal of the European Union.

This regulation addresses respiratory and skin hypersensitivity that can be caused by diisocyanates and requires training before handling relevant products containing diisocyanates.

To ensure that employees can continue to work safely with diisocyanates, new training requirements will become mandatory for professional and industrial users of products with a total concentration of monomer diisocyanate above 0.1 from August 24, 2023, and every five years thereafter.

Safe use and handling of diisocyanates training is now available for free for CPG UK customers via our chosen partner. 

Simply download our instructions on how to access the training, complete your course, and keep hold of your certificate. 

Remember - When using code "FEICA_21_C24" your training is free on CPG UK.

What does this restriction mean?


  • Products placed on the market from February 2022 must bear a clearly visible reference to the training requirements on the label. 
  • All products placed on the market must have the correct labeling of products.

Like any substance, diisocyanates are safe to use when the chemicals are handled in accordance with relevant risk management and safety precautions. 

It is important to emphasis that in fact no diisocyanates are found in final products. Diisocyanates are only used as reactive chemicals, meaning they react with the polyol to form the PU product and are used up in this process. 

Hypersensitivity means that a person can show an allergic reaction to the substance after exposure. If the person is hypersensitive, he or she may have a strong allergic reaction with respiratory consequences (e.g. asthma) whenever he or she comes into contact with it (even at very low concentrations). In most people with diisocyanate-associated asthma, improvement or complete recovery occurs after cessation of exposure.

The new regulation only applies to traders and industry. A separate restriction for consumer/DIY use already came into effect several years ago.

The new regulation was adopted on August 4, 2020, and entered into force on August 24, 2020. By August 24, 2023, all users of PU products must be trained and certified.

The legal requirements must be stated on the packaging of relevant products placed on the market after 24 February 2022 as substances on their own, as components of other substances, or in mixtures for industrial and professional use. In other words, products manufactured on or after February 24, 2022, must include this labeling. This can be read in point 2 of the Annex to Regulation (EU) 2020/1149 on diisocyanates, which includes Annex XVII of the European Parliament and of the Council on the Registration, Evaluation, Authorization, and Restriction of Chemicals ( REACH) is being amended.

The restriction is intended to prevent unsafe handling of diisocyanates and not to limit the availability of products. Due to their unique properties in many applications, PU products will continue to be widely available.
