Classify Your Shipment

The cost of shipping is based on certain characteristics of a shipment. For example, how much space does it take up and how much does it weigh? How easily can it be handled and stowed? What is the value of the shipment and what liabilities are associated with it?

To equitably assign rates to any one shipment, most carriers refer to the National Motor Freight Classification (NMFC).


What are the classifications?
The NMFC is a pricing tool developed by the National Motor Freight Traffic Association (NMFTA). The classifications establish groupings for virtually all commodities moving in interstate and intrastate transport. This gives both carriers and shippers a standard when agreeing on shipping prices.

What basic shipping characteristics are used to determine classifications?
NMFC groups all commodities into 18 classes (50 through 500) according to their "transportability." The four main characteristics used to evaluate the commodity include 1) density, 2) stowability, 3) ease or difficulty in handling, and 4) liability.

Why is a class required?
The NMFC does not set prices, nor does it specify any rates, revenues or charges. It does establish standard categories for pricing, allowing shippers and carriers to negotiate price based on standard shipping considerations. It also provides uniform rules, packaging provisions and Bill of Lading formats. Correct classification allows Estes Express Lines to offer you the best possible service and the most accurate rates.

How can I classify my shipment?
If you're not already familiar with the NMFC categories, simply call our Traffic department on (804) 353-1900, Ext. 2269.

Be sure to identify each commodity and its classification on your Bill of Lading to ensure that your shipment is properly rated. Some classifications require that the shipper declare the value and/or the density on the Bill of Lading as well. Call our Traffic department if you're unsure whether or not this information is necessary.
