Limited quantity markings
['Hazmat markings, Placards, and Labels']

A package containing a limited quantity of hazardous materials is required to be marked with one of the following:
- Non-air packages containing a limited quantity must display the square-on-point limited quantity marking. A package displaying the limited quantity marking is not required to be marked with the proper shipping name or identification number, unless the material is a hazardous substance or hazardous waste.
- Packages meeting the requirements for air transport must display the square-on-point “Y” limited quantity marking. A package displaying the “Y” limited quantity marking is required to be marked with the proper shipping name and identification number when transported by air. Packages displaying the square-on-point “Y” limited quantity marking are authorized for transport by all modes of transportation.
The width of the border forming the square-on-point marking must be at least 0.08 inches (2 mm). Each side of the marking must be at least 3.94 inches (100 mm). If the package size requires a reduced size marking, then each side of the marking may be reduced to no less than 1.97 inches (50 mm). For cargo transport units transported by water, each side of the marking must have a minimum size of 9.84 inches (250 mm).
