What you need to know

The limited quantity mark normally replaces the proper shipping name and ID number marking.

A hazardous substance or a hazardous waste inside pulls the full marking requirement back in.

A package displaying this mark is not subject to the marking requirements of § 172.301 of this subpart unless the limited quantity package also contains a hazardous substance or a hazardous waste.

49 CFR 172.315

172.315(a)(1) fixes the form: a square-on-point with black top and bottom portions and a white or contrasting center.

It carries no words and no class number.

The top and bottom portions of the square-on-point and the border forming the square-on-point must be black and the center white or of a suitable contrasting background

49 CFR 172.315

100 mm a side, measured outside the border, with the 2 mm border itself separate.

A reduction is allowed only where the packaging size forces one.

the minimum dimension of each side, as measured from the outside of the lines forming the border, must be 100 mm
