NMFC Code Lookup

An NMFC (National Motor Freight Classification) code is a standardized freight identification number used to classify cargo based on density, handling, stowability, and liability. It determines freight class, which directly affects LTL shipping rates and ensures pricing accuracy.

You can use FreightCenter’s NMFC Code Lookup Tool to search for the correct classification quickly. Enter your product type, and the tool will provide the matching NMFC code and freight class.

Using the wrong NMFC code can result in carrier reclassification, leading to:

• Unexpected freight rate adjustments
• Billing disputes and delays
• Additional fees from the carrier
  To avoid these issues, always verify your NMFC code before booking your shipment.

NMFC codes are primarily required for LTL freight shipments. If you’re shipping via full truckload (FTL), intermodal, or parcel, an NMFC code may not be necessary. However, some carriers may still require it for reference.

Each NMFC code corresponds to a specific freight class, ranging from Class 50 (lowest cost, most dense) to Class 500 (highest cost, least dense). The higher the freight class, the more expensive the shipping rate.

Example:

• Class 50: Heavy, dense products like steel parts (lower cost)
• Class 175: Lightweight, bulky items like furniture (higher cost)

The NMFC system categorizes freight based on these four key factors:

1. Density – Weight per cubic foot (higher density = lower freight class).
2. Stowability – How easily it fits in a truck (odd shapes or hazardous materials may increase class).
3. Handling – Fragile, oversized, or special-handling items have higher classifications.
4. Liability – Risk of damage, theft, or perishable nature affects classification.

No, NMFC codes and freight classes are standardized by the National Motor Freight Traffic Association (NMFTA), meaning carriers cannot change or negotiate classifications. However, working with a freight broker like FreightCenter can help you find cost-saving strategies.

The official NMFC codes are published by the NMFTA (National Motor Freight Traffic Association). You can access the full list through their website, but FreightCenter’s NMFC Code Lookup Tool makes it easy to find your specific code instantly.

Your freight class, determined by the NMFC code, directly affects your LTL freight rate. Lower freight classes mean lower shipping costs, while higher classes result in higher costs due to increased handling or space requirements.

• NMFC Code: A numeric identifier assigned to specific goods based on their characteristics.
• Freight Class: A general classification (ranging from 50 to 500) that helps carriers determine pricing and handling requirements.

Every NMFC code corresponds to a freight class, but not every freight class has only one NMFC code—similar products may have multiple NMFC codes depending on density and packaging.

Yes! Some products have multiple NMFC codes based on their packaging, density, or material composition. For example, the NMFC code for wood furniture varies if it’s assembled vs. unassembled or flat-packed vs. crated.

Yes, LTL carriers inspect shipments to ensure the correct NMFC code and freight class were used. If a carrier determines that the wrong NMFC code was applied, they will reclassify your shipment and adjust your rate accordingly.

Here are some frequently used NMFC codes and their freight classes:

If you’re unsure which NMFC code applies to your shipment, you can:

1. Use FreightCenter’s NMFC Code Lookup Tool for quick identification.

3. Check with the NMFTA’s official classification list for detailed freight categorization.

Avoid costly mistakes—verify your NMFC code before booking!

To get an LTL freight quote, you’ll need to provide the following:
Product description (What are you shipping?)
NMFC code & freight class (Use our lookup tool to find it)
Shipment dimensions & weight (Accurate info prevents reclassification)
Pickup & delivery locations (For rate calculation)

Once you have this info, enter it into FreightCenter’s freight quote tool to compare rates from top LTL carriers and book your shipment.
