HazardClassification
https://ontology.toxindex.com/v1/HazardClassification HazardA determination that a substance falls in a hazard class and category, with the hazard statements that communicate it, under the Globally Harmonized System of Classification and Labelling of Chemicals or a regulation implementing it. A classification is a judgment made by someone, so it carries at least one citation recording where it came from; sources may disagree, and each classification stands on its own rather than being a property of the substance. A substance assessed against a hazard class and found not to meet its criteria carries the not_classified category, which is distinct from having no classification at all.
