The obligation
Preparers must classify hazardous chemicals against GHS Rev. 3 criteria. The WHS Regulations directly reference GHS Rev. 3 for classification, and the Code details how to apply those criteria in the SDS.
Australia's model WHS Regulations adopt GHS Rev. 3 as the classification framework. Manufacturers and importers must classify each chemical (substance or mixture) against GHS hazard classes and categories to determine whether an SDS is required and what hazard information it must contain. The Code provides guidance on classifying mixtures, applying concentration limits, and using available data. Misclassification is a direct non-compliance risk.
