EU officially adopts new exposure limits for diisocyanates
European Parliament and Council The Council officially adopted new exposure limits for diisocyanates and published them in the Official Journal of the European Union. They are welcomed by industry associations ISOPA and ALIPA.
The new regulation sets the eight-hour time-weighted average occupational exposure limit (OEL) for diisocyanates at 6 μg/m3. Member states have until April 9, 2026 to incorporate the new limits into their national legislation.
Importantly, occupational exposure limits (OELs) will now be consistent across all member states, whereas previously there were different limits. “Establishing a level playing field in the EU is important to ensure a coordinated approach across all EU member states,” the associations said. They added that the new binding limits would require a coordinated approach across the value chain. Significant investment, as noted in the impact assessment accompanying the Commission’s original proposal. Therefore, they welcome the transition value of 10 μg/m3, which will apply until December 31, 2028.
They said: “This transition period will allow the EU polyurethane system downstream industry to strengthen risk management measures and implement best practices, thereby ensuring that the industry adapts to the new limits.”
“ We believe that these EU Occupational Exposure Limit (OEL) values, combined with mandatory training of workers under existing EU restrictions, will ensure a framework that adequately protects workers, taking into account socio-economic and feasibility factors, further An important step towards reducing cases of occupational asthma.” ISOPA and ALIPA are now planning to publish practical guidance for industry and professionals on how to comply with the new restrictions. This should be rolled out in the next few weeks.
