NMFC Codes & Freight Class Changes: What LTL Shippers Need to Know in 2025

Understanding how your freight is classified can mean big savings.

When shipping via Less-Than-Truckload (LTL), NMFC (National Motor Freight Classification) codes play a vital role in how your freight is priced, handled, and processed.

These codes are managed by the National Motor Freight Traffic Association (NMFTA) and are used to classify items based on:

• Density (weight per cubic foot)

• Stowability (ease of loading with other cargo)

• Handling (special care or equipment needed)

• Liability (risk of damage, theft, or special restrictions)

Each product is assigned a specific NMFC Item Number and a corresponding freight class, ranging from 50 (cheapest) to 500 (most expensive).

Big updates are coming to the NMFC system. Starting in July 2025, over 2,000 commodities without special handling needs will shift to a density-based classification system with 13 new freight class tiers.

🗓 Rollout Schedule:

• July 15 – Updates go live in the ClassIT online tool

• July 19 – Full implementation begins

These changes will simplify the classification process, improve pricing accuracy, and reduce errors.

Using the correct NMFC code and freight class ensures:

• ✅ Accurate pricing and quotes

• 🚫 No reclassification fees or delays

• 📦 Proper handling and safety for your goods

• 📋 Full compliance with LTL carrier requirements

Incorrect codes on your Bill of Lading (BOL) can result in surprise charges, delivery delays, or rejected shipments.
