Packages containing this type of substance shall bear the "EXPLOSIVE" subsidiary hazard label (Model No 1, see 5.2.2.2.2) unless the competent authority of the country of origin has permitted this label to be dispensed with for the specific packaging employed because test data have proved that the substance in this packaging does not exhibit explosive behaviour (5.4.1.5.5.1). The provisions of 7.1.3.1 shall also be considered.
