Product Stewardship



New European legislation on aromatic and aliphatic diisocyanate-containing products, entered into force on August 24, 2020. This regulation applicable in the European union aims at protecting the European workers, who are exposed to diisocyanates.

Watch this video with Mr Christian Léger, Vencorex Vice-President Sales & Marketing to learn more about it.

The target of this training is to ensure a safe use and handling of diisocyanates. So even though some products are exempted from the training obligation, it is recommended to follow the training in all cases.

Training content has been created by ALIPA/ISOPA and some Downstream user associations in a joint industry effort.

For more information, please visit the digital platform Safe use of Diisocyanates - Homepage, where various training options are available in different EU languages and where you can find useful guidelines such as :

The restriction is NOT A BAN : isocyanates continue to be available on the European the market. But industrial and professional users exposed to diisocyanates containing more than 0,1% isocyanate monomer in Europe have to successfully completed a minimum standardized mandatory training on safe use of diisocyanates.

The new legislation applied after 2 transition periods:

  • Since 24 February 2022:  suppliers have to provide the information on the packaging: “As from 24 August 2023 adequate training is required before industrial or professional use”
  • Since 24 August 2023: an employer or self-employed person has to ensure that industrial or professional user(s) and supervisors of these tasks, have successfully completed training on the safe use of diisocyanates prior to the use of the substance(s) or mixture(s) containing a concentration of diisocyanates > 0.1% by weight
