Where do I place the technical name on packages when shipping Dangerous Goods?

A question which comes to many of us while marking dangerous goods packages is, ‘how and where technical name is to be marked on these packages’.

Packages of Dangerous Goods assigned with special provision 274 shall be marked with technical name together with UN Number and proper shipping name.
