How to use the table 177.848(f)
In other cases, explosives of the same compatibility group but of different divisions may be transported together if the whole shipment is transported as though its entire contents were of the lower numerical division (i.e., Division 1.1 being lower than Division 1.2).
Example: A mixed shipment of Division 1.2 materials and Division 1.4 materials, both of compatibility group D, must be transported as Division 1.2 materials.
