More than a year after one of the most significant changes to less-than-truckload (LTL) freight classification in decades, the industry appears to have adapted more smoothly than many initially expected. However, transportation executives say there is still work to be done when it comes to helping shippers understand the new density-based system and how it can affect freight costs.
The National Motor Freight Traffic Association (NMFTA) introduced major changes to the National Motor Freight Classification (NMFC) system on July 19, 2025. The overhaul placed significantly greater emphasis on freight density while simplifying and modernizing commodity classifications used throughout the LTL industry.
A Smoother Transition Than Expected
Despite early concerns about how such a large change would affect LTL operations, carriers say the transition has generally gone well.
The updated system introduced a standardized 13-tier density model, replacing the previous 11-tier approach for applicable freight. It also removed or consolidated outdated commodity listings and created a more standardized way to classify freight based on its transportation characteristics.
Density has consequently become increasingly important when determining freight class. For shippers, that means accurately knowing the weight and dimensions of a shipment is more important than ever.
NMFTA continues to emphasize that freight classification is based on characteristics including density, handling, stowability and liability, with special considerations still applying to freight that presents unique transportation challenges.
Shipper Education Remains a Priority
Although carriers and logistics providers have largely adjusted to the changes, industry leaders say some shippers are still learning how the new classification structure affects their freight.
Incorrect measurements, outdated NMFC information or inaccurate commodity classifications can create problems ranging from billing discrepancies and reclassification charges to shipment delays and disputes.
NMFTA recommends that shippers regularly review their most commonly shipped commodities, update internal systems with current classification information, train employees involved in shipping and pricing, and work closely with carriers and 3PL partners to ensure classifications remain accurate.
Accurate dimensions are particularly important. Because density is calculated using both a shipment’s weight and the amount of space it occupies, even changes in packaging can potentially affect the applicable classification.
Technology Is Becoming More Important
The shift toward density-based classification also reinforces the importance of accurate freight data.
Transportation management systems, rating tools and other logistics platforms need current shipment information to produce accurate results. NMFTA specifically recommends keeping systems that reference NMFC item numbers and freight classes updated as classification standards continue to evolve.
For businesses managing large or complex transportation networks, having reliable shipment data and greater visibility can make these changes easier to navigate.
Logos Logistics supports customers through technology-enabled transportation management, including shipment scheduling, load configuration, route scheduling, carrier tendering, GPS capabilities and web-based reporting.
What LTL Shippers Should Do Now
Even if your company experienced little disruption when the NMFC changes were introduced, freight classifications should not be treated as a one-time update.
Shippers should continue to:
- Accurately weigh and measure freight before tendering shipments.
- Review commonly used NMFC classifications.
- Make sure bills of lading contain accurate shipment information.
- Recheck classifications when packaging, dimensions or products change.
- Keep TMS, rating and shipping systems updated.
- Educate warehouse, transportation, customer service and billing teams.
- Communicate with logistics providers when classification requirements are unclear.
NMFTA describes the NMFC as a living standard that will continue to evolve alongside changes in freight, packaging and transportation practices. ClassIT+ serves as its official digital source for current item changes, density scales and rule updates.
