Determining delivery charges for LTL shipments is much more complex than for small packages. In addition to the weight of the shipment and the distance it must travel, you must also specify a shipping classification. Shipments are classified on a scale from 50 to 500, according to a package's density, value, fragility, and storage requirements, with higher numerical ratings indicating higher per pound transportation costs.

To learn the class of your shipment, you can consult an LTL carrier or you can purchase the National Motor Freight Classification listing through the American Trucking Association (703/838-1700).

The final cost will include accessorial charges. These are extra charges for services such as storage, contacting the recipient or delivery to companies without loading docks.
