GHS Label Maker

Pick a substance and the pictograms, signal word and hazard statements come from the harmonised CLP Annex VI list. Enter the container volume and the label is sized to the rule that actually applies where you sell — or to the pack of blank labels you already own. The PDF is vector at true physical size, so 4 × 2 in prints 4 × 2 in.
