In May 2013, Regulation (EC) No 1272/2008, better known as CLP regulation, was updated based on the revised interpretations in the fourth edition of UN GHS. The updated CLP regulation aligned itself with its UN counterpart on “chemical hazard classification” and “principles for classification”. Similar moves also took place in Asian countries almost immediately afterwards. Many countries published their new versions of GHS or GHS-like regulations in the second half of the year, with China, Japan and Korea most notable.
