(1)Commission Regulation (EU) No 605/2014note, which was adopted on 5 June 2014, provides for the application of new or updated provisions for harmonised classification and labelling of a number of substances as from 1 April 2015. Due to some delays in the adoption process of that Regulation, the transitional period until the application of Regulation (EU) No 605/2014 is significantly shorter than those applied for previous adaptations to technical and scientific progress. 10 months appear insufficient to allow economic operators to adapt to the new rules, some of which affect widely used chemicals. The application date should therefore be deferred to allow for a transitional period that is in line with the practice for previous adaptations to technical progress of Regulation (EC) No 1272/2008.
