2025 NMFC Changes: What LTL Shippers Need to Know

‍

The LTL freight industry experienced its most significant classification overhaul in recent history during 2025. The National Motor Freight Traffic Association (NMFTA) implemented sweeping changes to the National Motor Freight Classification (NMFC) system, fundamentally reshaping how freight is classified and rated. For shippers, understanding these changes isn't just about compliance—it's about protecting your bottom line and avoiding unexpected costs.

What Changed: A Fundamental Shift in Classification

The NMFTA introduced two critical updates in 2025 through Docket 2025-1 (effective July 19, 2025) and Docket 2025-2 (effective December 2025). These changes represent a strategic pivot from commodity-based classification to density-based rating across the board.

Key Changes:

Over 2,000 commodities were recategorized and consolidated into broader categories

The density scale expanded from 11 tiers to 13 tiers, providing more granular classification options

Single-class items were transitioned to the new multi-tier density structure

Real-World Example: Consider NMFC 154800, which previously classified all faucets and sinks under a single freight class. Under the new system, this classification was consolidated into NMFC 158880—"Plumber's Goods"—which now uses the 13-tier density scale. Depending on the actual density of your specific products, this could mean your freight class (and therefore your shipping costs) may shift up or down.

The New 13-Tier Density Scale:

‍Note: PCF = Pounds per Cubic Foot

The Impact on Your LTL Program

Carriers have been rapidly adapting to this new landscape with strategic investments and operational adjustments:

Enhanced Technology: Carriers are deploying advanced weighing and dimensioning equipment to capture precise freight characteristics

Increased Scrutiny: Bill of lading (BOL) information is being reviewed more carefully than ever before

Revenue Protection: Carriers are actively managing the financial impact of these changes, particularly for dense freight that may have shifted to lower (cheaper) classes

What This Means for You: The likelihood of freight reclassification has increased substantially. If your commodity information isn't precise, or if your products fall into newly consolidated categories, you may face unexpected reclassifications during carrier inspections. These adjustments can lead to higher freight charges, billing disputes, and delays in your accounts payable process.

Additionally, if these changes affect your typical freight class distribution, your existing Freight All Kinds (FAK) agreements may no longer align with your actual shipping profile. FAK bands that worked perfectly before may now need adjustment to account for the shifted rating structure.

The Cost of Inaccuracy

While the NMFTA's goal is to create a more standardized and organized freight classification system, the transition period presents significant risk for shippers who haven't updated their processes. Inaccurate commodity information on your BOL can trigger a cascade of problems:

·      Unexpected cost increases from freight reclassification

·      Billing adjustments and disputes that delay payment processing

·      Audit complications that tie up resources

·      Strained carrier relationships due to repeated classification errors

The key to avoiding these issues is proactive adaptation—ensuring your commodity classifications are accurate under the new system before problems arise.

How to Adapt: A Strategic Approach

The most effective way to minimize the impact of these NMFC changes is to conduct a comprehensive review and update of your commodity classifications. However, this is easier said than done. The process requires:

·      Detailed product-by-product NMFC verification

·      Accurate density calculations and class range validation

·      Analysis of your shipping data to identify patterns and risks

·      Assessment of how changes affect your overall freight costs and FAK structures

This level of analysis is time-intensive and requires both LTL expertise and attention to granular detail—often examining individual line items across thousands of shipments.

Our Approach: Freight Classification Validation

As LTL advisors, our mission is to take this burden off your shoulders. We specialize in freight classification validation—a comprehensive service designed to ensure your commodity data is accurate, compliant, and optimized under the new NMFC structure.

Our Process:

1. Deep-Dive Analysis: We analyze your complete product catalog alongside your historical shipping data, examining patterns down to individual line items to understand your freight profile.

2. Accurate Classification: We verify that each product has the correct NMFC code and that density and class ratings align with the new 13-tier structure.

3. Cost Impact Assessment: We model the financial impact of the NMFC changes on your freight spend and identify opportunities for optimization.

4. FAK Optimization: We evaluate whether your existing FAK agreements need adjustment to reflect your updated freight class distribution.

By partnering with us, you gain the benefit of specialized expertise without diverting your internal resources from core business operations.

Looking Ahead

The 2025 NMFC updates represent one of the most substantial shifts in LTL freight classification in recent years, but they won't be the last. The NMFTA continues to refine and adjust the system as the industry evolves. Shippers who stay ahead of these changes—and partner with experts who monitor them closely—will maintain a competitive advantage.

As your LTL advisors, we make it our mission to know your freight inside and out. We stay current on industry changes, proactively alert you to impacts on your program, and help you adapt seamlessly. Our goal is simple: to set you up for success in an ever-changing freight landscape.
