The National Motor Freight Classification (NMFC®) changes that took effect in July 2025 fundamentally changed how many Less-Than-Truckload (LTL) shipments are classified and rated.
For years, many shippers relied primarily on commodity-based classifications. Today, freight density plays a much larger role in determining freight class, making dimensions and weight more important than ever. More than 2,000 commodity listings were revised, consolidated, or moved toward density-based classification, and the traditional 11-tier density scale was expanded to a 13-tier scale.
For warehouse teams shipping palletized freight, one simple reality has emerged:
Bad measurements now cost more money than ever.
Many organizations still rely on tape measures, manual estimates, or dimensions entered from old shipping records.
Unfortunately, carriers don't.
Today's carriers increasingly use automated dimensioning systems to verify shipment dimensions and density. If the dimensions on the Bill of Lading don't match what the carrier measures, the shipment may be reclassified, resulting in additional charges, billing disputes, and administrative headaches.
Common causes of costly reclassifications include:
Even a few inches can significantly impact density calculations and freight class.
The NMFC updates introduced a standardized density-based approach for many commodities. For qualifying freight, class determination now relies heavily on pounds per cubic foot (PCF), making shipment dimensions a critical part of the rating process.
Consider two pallets weighing the same amount:
| Shipment | Weight | Dimensions | Density Outcome |
|---|---|---|---|
| Pallet A | 500 lbs | Compact footprint | Higher density, potentially lower class |
| Pallet B | 500 lbs | Larger footprint | Lower density, potentially higher class |
The freight weighs exactly the same.
The shipping cost may not.
Under today's NMFC rules, the dimensions of the pallet can directly impact freight classification and transportation costs.
Since the NMFC classification updates took effect, many of the warehouse and logistics teams we speak with have noticed increased scrutiny around shipment dimensions and freight classification accuracy.
Carriers are validating shipment characteristics more frequently than in the past, creating challenges for organizations that still rely on manual measurements, estimated dimensions, or outdated shipment records.
As a result, many shippers are evaluating whether their current measurement processes provide the consistency and documentation needed to support today's freight classification requirements.
Since the NMFC transition, many operations teams are experiencing:
Unexpected Freight Chargebacks: Carriers identify dimensional discrepancies, resulting in adjusted invoices and reclassification fees.
Increased Administrative Work: Teams spend valuable time researching freight bills, validating measurements, and disputing carrier adjustments.
Inconsistent Data Across Locations: Multi-site operations often have different measuring processes, creating inconsistencies that lead to classification errors.
Slower Shipping Workflows: Manual measurement processes create bottlenecks at receiving and shipping stations.
Most warehouse shipments move on pallets.
Unfortunately, pallets are also one of the hardest shipment types to measure consistently.
Warehouse personnel must account for:
The result is inconsistent dimensional data that can create costly downstream problems.
Instead of manually measuring every pallet, mobile dimensioning allows warehouse personnel to capture dimensions directly from a handheld device.
Using MobileDemand's dimensioning solutions, users can quickly capture:
The data can then be sent directly to warehouse management, transportation management, ERP, or shipping systems.
This creates a more consistent and repeatable process while reducing manual data entry.

If you're shipping palletized freight under today's NMFC rules, ask yourself:
If any of these questions are difficult to answer, it may be time to evaluate your measurement process.
The 2025 NMFC changes didn't just update freight classifications - they increased the importance of consistent, reliable shipment data across the entire shipping process.
As density-based classification becomes the standard for many commodities, pallet measurements have become a critical factor in freight costs, compliance, and operational efficiency. Organizations that continue relying on manual measurements and inconsistent processes may find themselves spending more time resolving discrepancies, managing chargebacks, and supporting freight classification decisions.
For shippers looking to improve measurement consistency and reduce freight disputes, mobile dimensioning solutions such as xDIM and xPIM provide a practical way to capture pallet dimensions directly at the source.
