0408, UN 0409, UN 0410, UN 0455, and UN 0456. These explosives may be 

mix-packed with each other in accordance with the compatibility 

requirements prescribed in paragraph (e).

    (d) Division 1.1 and 1.2 explosives may not be packed with the 

following explosives: UN 0333, UN 0334, UN 0335, UN 0336, and UN 0337.

number may be packed together.

    (2) Explosives of the same compatibility group or authorized 

combination of compatibility group but different division number may be
