Skin corrosion - category 1A (H314): concentration >= 50%;
Skin corrosion - category 1B (H314): 10% <= concentration < 50%;
Skin irritation - category 2 (H315): 1% <=  concentration < 10%;
Eye irritation - category 2 (H319): 1% <= concentration < 10%;
Oxidising liquid - category 1 (H271): concentration > 50%;
Oxidising liquid - category 2 (H272): concentration <= 50%
Notes B (Some substances (acids, bases, etc.) are placed on the market in aqueous solutions at various concentrations and, therefore, these solutions require different classification and labelling since the hazards vary at different concentrations.Entries with Note B have a general designation of the following type: ‘nitric acid … %’.In this case the supplier should state the percentage concentration of the solution on the label. Unless otherwise stated, it is assumed that the percentage concentration is calculated on a weight/weight basis.)
17 (Generic cut off concentrations also apply to this chemical in addition to the specific cut off concentration(s) above. Refer to the generic cut off concentration table on the Reference Information page of HCIS (http://hcis.safeworkaustralia.gov.au/UserGuide).)

EU (Classification information for chemical is taken from the European Union’s Classification, Labelling and Packaging (CLP) Regulation.)
