Freight Class Codes Guide: What Are NMFC Codes?

NMFC System Overview

If you want to ship freight the right way, you need to know about the NMFC system. The National Motor Freight Classification, or NMFC, is a standard that people use in North America. It helps you compare different things that are shipped across states and countries. The NMFC system puts items into 18 different freight classes. These classes go from 50 up to 500. If your item has a lower number, it is heavy and easy to move. If your item has a higher number, it is light, big, or needs special care.

The National Motor Freight Traffic Association (NMFTA) makes and updates the NMFC. The Freight Classification Development Council (FCDC) helps NMFTA keep the system current. NMFTA gives out new updates every three months. You should always know about these changes to keep your shipping easy.

Tip: Check the newest NMFC codes before you ship. This helps you stop mistakes and extra costs.

How Freight Classes Are Determined

You pick a freight class by looking at four main things. These things help you see how simple or hard it is to move your shipment. The four main things are:

• Density: This means how much your freight weighs compared to its size. If your item is less dense, it gets a higher class.

• Handling: If your shipment is hard to move or needs special care, it gets a higher class.

• Stowability: This shows how well your items fit with other shipments in a trailer. If your items do not fit well, they get a higher class.

• Liability: If your items are worth a lot or break easily, they get a higher class.

You need to measure and weigh your shipment the right way. You also need to think about how you pack your items and if they need special care. The NMFC system uses these four things to make sure every shipment gets the right class.

Why Classification Matters

You have to use the right freight classification for every shipment. If you use the wrong class, you might have problems like delays, extra charges, or even denied claims. Carriers can look at your shipment and change the class if they find mistakes. This can mean you pay more and your delivery is slower.

The NMFTA helps you get the right class. They give you tools, training, and help to understand the NMFC system. They also work with carriers and shippers to keep things fair.

Note: Using the right classification keeps you safe from problems and helps you save money.

The freight class codes guide gives you the facts you need to ship with confidence. When you follow the NMFC codes, your freight moves safely and without trouble.

Key Factors in Freight Classification

Density and Measurement

You need to know the density of your freight to assign the right freight classification. Density means how much your shipment weighs compared to its size. To find density, measure the length, width, and height of your package in inches. Multiply these numbers to get the cubic inches, then divide by 1,728 to get cubic feet. Next, divide the weight in pounds by the cubic feet. This gives you the density in pounds per cubic foot.

Here is a table that shows how density matches with freight class:

To measure your freight, you can use tools like Parcel Ultima Pro, Pallet Ultima Pro, or a Dimensional Weight Scanner. These tools help you get accurate numbers, which is important for correct freight classification.

Stowability and Handling

Stowability looks at how well your freight fits with other shipments in a truck. If your items are odd-shaped or hazardous, they may need special storage. This can raise your freight class because it makes transportation harder. You want your freight to stack and fit easily to keep costs down.

Handling checks how easy it is to move your shipment. If your freight needs special equipment or extra care, it gets a higher class. Carriers look at how your freight is packed and if it can be loaded or unloaded without problems.

• Stowability affects NMFC codes for irregular or hazardous items.

• Irregular shapes or dangerous goods often need special storage.

• Special handling increases the freight class.

Liability Considerations

Liability means the risk of damage, theft, or loss. If your freight is valuable or fragile, it gets a higher class. Carriers want to know if your shipment needs extra protection. You should pack your freight well and label it clearly. This helps lower the risk and keeps your shipment safe during transit.

Tip: Always check if your freight needs extra insurance or special handling. This can help you avoid problems and extra costs.

How to Assign the Correct Freight Class

Step-by-Step Freight Classification

You need to follow some steps to pick the right freight class. This helps you stop mistakes and extra fees. The NMFTA says to do these things:

1. Measure and Weigh
   Use a tape measure to check the length, width, and height in inches. Weigh your shipment in pounds. Make sure you count the packaging too.

2. Calculate Volume
   Multiply the length, width, and height together. This gives you the total cubic inches. Divide that number by 1,728 to get cubic feet.

3. Calculate Density
   Take the weight in pounds and divide it by the cubic feet. This tells you the pounds per cubic foot. Density is key for picking the freight class.

4. Determine Freight Class
   Use the density to find the freight class in the NMFC book or online. Each class has its own density range and handling needs.

5. Identify NMFC Number
   Find the NMFC number that matches your shipment’s type and density. You need this number for booking and paperwork.

Tip: Always measure your shipment. Do not guess. Guessing can cause mistakes and cost more money.

Using NMFC Codes and Directories

You should check official sources to make sure your freight class and NMFC code are right. The NMFTA makes the official NMFC directory. You can use online tools to look up codes faster. Here are some trusted places:

Use these directories to double-check your freight class before you ship. The NMFTA updates the list often to match new changes. If you are not sure, ask your carrier or freight forwarder for help.

Note: Talking with your carrier or freight forwarder helps you avoid mistakes. It also makes sure your shipment follows all the rules.

Freight Class and Shipping Costs

Rate Calculation

It is important to know how freight class changes shipping costs. Carriers use freight class to set prices for shipments that do not fill a truck. This system puts your goods into groups by density, stowability, handling, and liability. Each group has a number from 50 to 500. Lower numbers mean you pay less. Higher numbers mean you pay more. Carriers use these numbers to keep prices fair for everyone.

• Freight class helps carriers give the right price.

• Higher freight class codes mean you pay more per pound.

• Every item gets an NMFC code. This helps carriers see how hard it is to ship.

• If you use the wrong class, you may pay extra fees.

You can save money by picking the right class and checking your NMFC code before you book.

Carrier Selection

Carriers use NMFC codes to see if they can ship your items. They look at things like density, handling, stowability, and liability. These things help carriers set prices and see if your shipment fits their trucks.

Every product has a freight class and an NMFC code. Some NMFC codes are different even in the same class. Carriers use this to set prices and decide if they will ship your items.

Operational Efficiency

Using the right NMFC code helps your shipping go smoothly. When you use the correct codes, carriers can load and move your items faster. This helps use space better and makes delivery quicker. You also avoid delays and extra costs.

• Using the right code helps with handling and cost control.

• NMFC codes help carriers use space and plan routes better.

• Freight class calculators and digital tools help stop mistakes and keep prices right.

Tip: Use digital tools and check your NMFC codes. This helps keep shipping costs low and prices correct.
