It is estimated that 65 - 75 % of REACH registration dossiers contain data gaps or obsolete data potentially leading to non-compliance. That's why the European Chemicals Agency (ECHA) is putting the issue of dossier quality and dossier updates at the very top of the list of priorities for upcoming years. ECHA's director, Bjorn Hansen, reported that REACH lacks clear incentives for companies to update registration dossiers, just about a year after ECHA's former director, Geert Dancet, mentioned that the industry is misinterpreting REACH dossier update obligations. That was back in 2017. Now some of the EU member states are calling for REACH dossier update Regulation, forcing the registrants to check and update their registrations on regular basis. We will take a close look at the latest developments in dossier quality, dossier updates and any potential upcoming regulatory measures associated with this challenging issue.
