Introduction to DOT Limited Quantitites

 

What is a DOT Limited Quantity?

The formal definition of a Limited Quantity from the Pipeline and Hazardous Materials Administration (PHMSA) is as follows:

Limited quantity, when specified as such in a section applicable to a particular material, means the maximum amount of a hazardous material for which there is a specific labeling or packaging exception.

49 CFR 171.8 “Limited quantity”

In simpler terms, a limited quantity in an amount of hazardous material small enough to be less hazardous and therefore requires less stringent packaging and labeling compared to other hazardous shipments.

What Exceptions are made for Limited Quantity Shipments?

The full text describing exceptions to the shipping rules for limited quantity materials can be found in 49 CFR Part 173.156. In addition to the exceptions listed in the linked text, there are other exceptions within Part 173 pertaining to more specific exceptions by hazard class and transportation method.

Gross Weight Limitation

The base gross weight limitation is 30 kg (66 lbs). For certain materials, this limitation can change.

This gross weight limitation can also change in certain packaging styles. This is particularly notable with multiple smaller, inner packages contained in corrugated fiberboard trays, as described in 49 CFR 173.156(b)(2).

Display packs of consumer goods can also have exceptions to the 30 kg gross weight limitation as described in 49 CFR 173.156(c).

Limited Quantity Markings

Markings, described more in our Markings Guide, are a means of clearly identifying the contents of a package with a standardized technical name and a subset of pictograms not otherwise covered by the Labels or Placards. The Limited Quantities pictogram is included in this group.
