REACH Training requirements for diisocyanates

About the legislation

Diisocyanates listed in Entry 74 in Annex XVII shall not be used as substances on their own, as a constituent in other substances or in mixtures for industrial and professional use(s) after 24 August 2023, unless:

(a) the concentration of diisocyanates individually and in combination is less than 0,1 % by weight, or 

(b) the employer or self-employed ensures that industrial or professional user(s) have successfully completed training on the safe use of diisocyanates prior to the use of the substance(s) or mixture(s).


Restriction list in iChemistry

We have since September 12, 2022, offered a restriction list for REACH Training requirements for diisocyanates, so that you can keep track on your chemicals products that contain diisocyanates. This list is given as a standard list for all customers operating in the EU.

The matching criteria (CAS/EC number) will only generate a match if sum of concentration of matched CAS/EC is 0,1% or more. This is because the training requirement only applies if concentration is above 0,1%.

Besides the CAS and EC-numbers that you can find in Annex XVII Entry 74, our EHS consultants have supplemented the list with some additional diisocyanates covered by the requirements.

If you see that you have products inventoried in iChemistry that match the list for these training requirements, you can start by examining which substance is causing the matching and in what concentration that substance is in the product.

To do this, go to the product's iSafe/Product information> Restriction and Prohibition Lists and see the substance name under Reason

Then go to Show composition (or section 3 in the SDS) to see the concentration level for that substance. This way you see if the substance that causes the matching is present in high concentrations in your chemical product or not.

The education requirement in the REACH restriction covers diisocyanates (those found in entry 74 Annex XVII) where the concentration is above 0.1% by weight regardless of classification.
