REACH – the European Regulation on Registration, Evaluation, Authorisation and Restriction of Chemicals – entered into force on 1 June 2007.

It aims at enhancing the protection of human health and the environment from the risks chemical substances could pose; while enhancing the competitiveness of the EU chemicals industry. 


In 2012, both m-tolylidene diisocyanates (TDI) and Methylene diphenyl diisocyanate (MDI) were included in the first Community Rolling Action Plan for Substance Evaluation.




-          TDI


TDI was evaluated in 2013 by Polish authorities that concluded that there was no need for further risk management measures. The assessment noted in particular that there was no data gap in the registration dossier and that TDI is not a Persistent, Bio-accumulative and Toxic (PBT) substance.


-          MDI


4,4'-MDI and MDI mixed isomers substances are currently being evaluated by the Estonian REACH competent authorities.


Risk Management Options Analysis


In 2014, the German Federal Institute for Occupational Safety and Health (BAuA) performed a Risk Management Option Analysis on diisocyanates and concluded that unconventional restrictions were the most relevant regulatory option in order to further improve workplace safety.
