REACH Legislation

REACH is the European Regulation on Registration, Evaluation, Authorisation and Restriction of Chemicals. It entered into force in 2007, replacing the former legislative framework for chemicals in the EU.

On 4 February 2020, the REACH Committee (established under REACH, consisting of representatives of the Member States and the EU Commission) voted in favour of the European Commission’s proposal for a REACH restriction on diisocyanates. The Restriction was published on 4 August 2020 applying from 24 August 2023 after a transition period of 3 years.

The Restriction on Diisocyanates is available in all official EU languages here.

Training levels

The Restriction specifies 3 different levels of training required for various uses of diisocyanates, 
the General Training as a minimum requirement and depending on the exposure an Intermediate Training and an Advanced Training. This matrix will help you to select the right training course.
