Entry 56 of Annex XVII to REACH - Methylenediphenyl diisocyanate (MDI)

Does the entry 56 of Annex XVII cover, besides the MDI monomers, also the oligomers and polymers of MDI?

The polymeric MDI, with CAS number 9016-87-9, is not included in the definition of the substance with CAS 26447-40-5 and moreover is not classified as dangerous in Annex VI of Regulation (EC) No 1272/2008 (CLP). In the Risk assessment report and Risk reduction strategy performed by the Belgian Rapporteur, two main products were analysed during the exposure assessment and throughout the decision making process: the one-component foams and hot melt adhesives, both containing respectively 10% and 2% of MDI. Other products with MDI content below 0.1% did not pose any risk and therefore were excluded by the final consideration on the risk reduction measures under Directive 76/769/EEC. However, polymeric MDI present in mixtures is covered by the restriction when such mixtures contain more than 0.1% of MDI (as defined in the RAR). Therefore, dimers and polymeric forms of MDI are out of the scope of the current restriction except if they are part of mixtures containing more than 0.1% of MDI.
