Aviation - Limited Quantities

Unless otherwise noted in the HMR, a package containing a limited quantity of hazardous materials is not required to be marked with the proper shipping name, provided it is marked with the identification number, preceded by the letters "UN" or "NA" as applicable, placed within a square-on-point border with the ID number marking placed on a durable surface, and legible and of such a size relative to the package as to be readily visible. The marking must be applied on at least one side or one end of the outer packaging. When two or more hazardous materials with different ID numbers are contained in the package, the packaging must be marked with either individual diamonds bearing a single ID number or a single diamond large enough to include each applicable ID number.
