Belgium SDS Authoring The EU has fully adopted GHS under their CLP Regulation (Regulation on classification, labeling and packaging of substances and mixtures). The deadline for having new SDSs has passed for pure substances – it was November 30, 2010. The deadline for mixtures was May 31, 2015. Not all the building blocks in the United Nations Purple Book were adopted by the EU CLP regulation. Furthermore, the EU has adopted the EU No 453/2010 format for SDSs, which goes well beyond what was recommended in the Purple Book.
