Understanding the NMFC Changes – Why GPC is Your Ideal Solution

What is NMFC?

The National Motor Freight Classification (NMFC®), overseen by the National Motor Freight Traffic Association (NMFTA), is the system that determines how less-than-truckload (LTL) freight is classified in the U.S. Freight class (ranging from 50 to 500) is based on four key factors: density, handling, stowability, and liability.

In July 2025, major updates to NMFC rules went into effect, changing the way many commodities are classified and how density impacts pricing. For shippers, 3PLs, and carriers, the stakes have never been higher—accurate measurement of freight is now essential.

Key NMFC Freight Classification Changes in 2025

The NMFTA’s July 2025 update introduced one of the most significant overhauls in recent years:

- Greater emphasis on density: Density now plays a larger role in determining freight class unless other factors (handling, liability, stowability) dominate.

- More detailed density scale: The number of density breaks increased from 11 to 13 sub-scales, making classifications more precise.

- Commodity redefinitions: Many NMFC item headers were consolidated or updated to better reflect real-world handling and packaging.

Although some carriers are delaying strict enforcement of reclassification charges, the message is clear: freight must be measured and documented accurately to avoid costly errors.

Why Accurate LTL Freight Measurement Matters More Than Ever

Misclassifying freight leads to:

- Unexpected surcharges when carriers reclassify after pickup.

- Overpayment when density is underestimated.

- Delays and inefficiencies caused by rework in warehouses or at terminals.

- Safety risks if liability or handling requirements aren’t reported correctly.

With the new NMFC rules, relying on guesswork or tape-measure estimates isn’t enough. Precision is now the difference between profit and penalty.

How GPC’s 3D Freight Measure Software Solves NMFC Challenges

At GPC, we’ve designed our 3D Freight Measure software to meet exactly these challenges.

Here’s how our technology helps you stay compliant and efficient:

- Instant, accurate measurements: Capture dimensions and volume of parcels, pallets, and irregular freight in seconds—shrink-wrapped or not.

- Measure multiple items at once: Eliminate time-consuming manual checks by dimensioning stacked or mixed freight together.

- Flexible pallet inclusion: Choose whether to include or exclude pallets in volumetric calculations—crucial when density determines class.

- Versatility across environments: Works with handheld devices, forklifts, conveyors, and even in low-light warehouse conditions.

- Seamless integration: Push data directly into your WMS or TMS, ensuring quotes, billing, and classifications are always backed by accurate measurements.

Turning NMFC Rule Changes Into a Competitive Advantage

Rather than viewing the NMFC changes as a hurdle, companies can see them as a chance to sharpen operations. With GPC’s 3D Freight Measure software, you can:

- Avoid misclassification penalties with precise, documented data.

- Optimise freight spend by ensuring density-based classes reflect the true characteristics of your shipments.

- Enhance customer trust with accurate quotes and fewer billing surprises.

- Stay ahead of enforcement as carriers phase in stricter compliance.

Final Thoughts: Stay Ahead of NMFC Changes with GPC

The NMFC updates are reshaping how the industry measures and bills freight. The winners will be the companies that move from rough estimates to reliable, data-driven precision.

At GPC, we provide the tools to make that shift simple and cost-effective. By automating freight measurement, we help you classify correctly the first time—protecting margins, reducing risk, and keeping your operations compliant with the new NMFC rules.
