The restriction on diisocyanates, amending Annex XVII to Regulation (EC) No 1907/2006 of the European Parliament and of the Council concerning the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) is available in all official EU languages here.

To ensure that workers across the EU can continue to handle diisocyanates safely, new training requirements will become mandatory for professional and industrial users under the EU’s REACH Regulation from 24 August 2023.

The user of diisocyanates - either the employer of the user or the self-employed person - must complete and document the completion of the training.
If you do not comply with these mandatory trainings, you will no longer be allowed to work with with products containing diisocyanates exceeding the 0.1% limit established by Regulation (EU) 2020/1149.
ISOPA/ALIPA and our industry partners are organizing a comprehensive training programme to ensure the safe use of diisocyanates for producers and professional users all over Europe.

Here is what you need to do

1. Go to the Safe Use of Diisocyanates website to read more about the training requirements and how they might apply to you.

2. Ensure that you are following the link below to receive training and certification for the safe handling of diisocyanates. To participate in the free training program, go to the training platform and use the Mapei code*: FEICA_21_C16

*The Mapei FEICA code does not expire, but it is valid only for the trainings on the use of sealants and adhesives which can be found by clicking on the 'Adhesives & Sealants' picture on the training website.



ISOPA is the European trade association for producers of aromatic diisocyanates and polyols – the main building blocks of polyurethanes. ALIPA is the European Aliphatic Isocyanates Producers Association.

ISOPA/ALIPA works to promote the highest level of best practices in the distribution and use of diisocyanates and polyols in Europe and ensures that all stakeholders can easily access accurate and up-to-date information on these substances.
