Unpacking the new LTL Freight Class Changes

The National Motor Freight Traffic Association (NMFTA) is introducing a new round of updates to the National Motor Freight Classification (NMFC), set to take effect on July 19, 2025. These changes are aimed at modernizing freight classification, improving consistency, and better aligning classifications with current shipping practices. For professionals in logistics, LTL freight, and supply chain operations, understanding these updates is critical to avoid reclassification fees, shipment delays, or margin erosion.

Here’s a breakdown of what’s changing, who it affects most, and how to prepare.

Key NMFC Changes Effective July 19, 2025

1. Reclassification of Common Commodities

Several widely shipped commodities are being reclassified based on revised density breaks, stowability, and handling characteristics. Expect adjustments in classes for items like:

  • Flat-packed furniture
  • Consumer electronics
  • Medical equipment
  • Auto parts and accessories

Lower or higher class assignments may affect your freight charges, depending on how your items meet the new density thresholds.

2. New Density Guidelines

Updates to density-based items now include more granular classification ranges. The class boundaries for density tiers are shifting slightly, which could impact freight class for borderline shipments. Make sure you recheck your product’s PCF (pounds per cubic foot).

3. Consolidation of Obsolete Subclasses

The NMFTA is eliminating or merging certain outdated subclasses. This reduces redundancy and helps streamline classification for frequently misunderstood product types. If you’ve relied on legacy subclass codes, now is the time to verify if they’ve been retired or consolidated.

4. Updated Packaging Requirements

Some classifications will now carry stricter packaging stipulations. Items with fragile or irregular characteristics may require reinforced packaging or specific palletization methods to maintain their freight class and avoid upcharges.

Who’s Most Affected?

These changes will have the biggest impact on:

  • LTL Shippers who regularly move multi-class freight
  • Freight Brokers who manage carrier agreements and quoting
  • Third-Party Logistics Providers (3PLs) with diverse product categories
  • Manufacturers with products near class breakpoints or recent product redesigns

If your team ships products that straddle the line between density classes or if you’ve experienced reclassification issues in the past, pay particular attention to these updates.

How to Prepare

1. Audit Your Product Classifications

Review your most commonly shipped SKUs and compare their current classifications against the upcoming NMFC table. Use updated density calculators and be conservative—assume higher-class rates if you’re unsure.

2. Update Your TMS and Rate Tools

Ensure your transportation management system (TMS), quoting software, and API-based rate engines are updated with the new NMFC data on or before July 19th. Even a one-day delay can cause quote mismatches or reclassification fees.

3. Communicate with Your Carriers

Get ahead of potential disputes by proactively speaking with your LTL carriers. Ask if they’re adjusting their rating logic based on the new NMFC and if they anticipate any major reclassifications.

4. Retrain Shipping Teams

Your warehouse and fulfillment staff should be aware of the packaging changes and revised class requirements. Even subtle changes in pallet configurations or packaging integrity can now trigger higher costs or rejections.

5. Watch Your Invoices

Post-rollout, monitor your freight bills for a spike in reclassification or inspection charges. If you notice anomalies, dispute quickly and request the inspection reports. The first 60 days post-change are the most volatile.

What to Watch for After July 19th

  • Initial Carrier Flexibility: Some carriers may offer leniency for misclassified items during the first few weeks, but don’t count on it lasting.
  • Rate Volatility: Expect fluctuations in base LTL rates as carriers recalibrate to the new classifications.
  • Volume Reclassification Trends: Watch for any patterns—if multiple SKUs are suddenly being reclassed, it’s likely a systemic issue that needs reengineering.

Final Thoughts

The July 19, 2025 NMFC changes aren’t just another update—they carry real operational and financial implications. Proactive logistics professionals will take this moment to revalidate their freight data, tighten up packaging protocols, and ensure their tech stack reflects the new classification structure.

Staying ahead of NMFC changes helps protect margins, improve carrier relationships, and prevent unpleasant surprises when the freight bills arrive. Use the coming days wisely for a graceful transition.
