    Except for transportation by aircraft or as otherwise provided in

forming the square-on-point must be at least 2 mm and the height of the 
ID number must be at least 6 mm. The marking must be applied on at least 
one side or one end of the outer packaging.
    (b) When two or more hazardous materials with different ID numbers 
are contained in the package, the packaging must be marked with either 
individual square-on-points bearing a single ID number, or a single 
square-on-point large enough to include each applicable ID number.
