1-3 Load Types

In the transportation industry, the term load is defined as a quantity of material assembled and packed as a shipping unit. Generally, packages are classified into three load types based on the nature of the contents, how well the packaging protects it, and the strength of the mailing container.

1-3.1 Easy Loads

Easy loads include moderate-density items that can completely fill the mailing container or be packed in interior receptacles. Easy loads are not readily damaged by shock, compression, or puncture during handling or mail processing. They do not shift or move within the container, and they usually do not endanger other parcels.

1-3.2 Average Loads

Average loads include moderately concentrated items that usually provide partial support to all surfaces of the mailing container. Often, the item can be damaged if the package is compressed.

Average loads can be placed directly into a container or into separate interior containers. Nesting items within partitions or separate paperboard boxes can stabilize an average load and prevent damage to the container and the items.

1-3.3 Difficult Loads

The items in difficult loads usually need additional protection against shock, puncture, or distortion during handling or mail processing. Fragile objects, delicate instruments, high-density items, and small bulk items are considered difficult loads. Paper boxes, paper or plastic bags, or wraps of any kind cannot support difficult loads and are not acceptable containers for such items.
