Unishippers' Guide to Understanding LTL Freight Classification

Even with all of the information out there about freight classification (or freight class), learning how to classify your LTL freight shipments can still feel daunting. Unishippers is here to help simplify the freight classification process with our simple 3-step guide.

Download Unishippers' guide to learn the three most important steps to classifying your freight correctly, including:

  • Finding the correct NMFC code
  • Determining the proper freight class
  • Filling out your bill of lading accurately

A little background knowledge goes a long way

The National Motor Freight Association (NMTA) established the standard for freight identification and classification to provide a consistent comparison of freight commodities. Commodities are grouped into one of 18 classes based on the shipment's density, handling, stowability and liability. Together, these four characteristics establish a commodity's transportability and associated LTL shipping rate.

How does density factor into it all?

Density is the ratio of weight compared to volume. It is important that you get accurate shipment measurements in order to calculate your freight class density, or you could be at risk for reclassification.

What if my bill of lading is wrong?

The accuracy of your bill of lading is entirely dependent on how you classify your LTL freight. If your bill of lading includes mistakes, your shipment is subject to additional fees and delivery delays.

Unishippers' team of shipping experts is here to help you accurately identify your shipment's freight class. Along with the three simple steps outlined in this guide, our freight class calculator can help you calculate your freight density and determine the proper NMFC code for your LTL freight shipment.
