Additional information

Justification for classification or non-classification

Hydrazine salts have been classified under the DSD (67/548/EEC) and CLP regulation. These classifications do not include a classification for explosiveness, therefore hydrazine mono-nitrate has not been classified. Hydrazine mono-nitrate will not be explosive with the 55% water content as per the registered substance.
