hazard class
also called GHS hazard classification
A UN Globally-Harmonised-System / dangerous-goods hazard classification the product carries — the anchor of a qualified bundle, a hazard-type token (flammable, corrosive, toxic, oxidiser, and so on) naming HOW the product is hazardous. Cardinality many, because a dangerous good carries several classifications at once (a can of acetone is both flammable and an irritant), each its own statement carrying its own pictogram and signal word. The classification drives the printed GHS label and the product's shippability. Distinct from a consumer warning (compliance `warning` — free-text mandatory caution copy, a different speech act) and from a certification (a borne conformity mark): a hazard class is the structured dangerous-goods classification of the substance itself. Region-neutral: the international GHS/UN class, never a jurisdiction-specific artifact.
