Why Is My Freight Getting Reclassed?

BySarah Moll

Freight reclassification happens when a carrier decides the class you entered on your bill of lading (BOL) is wrong. And when that happens, you get hit with extra charges — often without warning.

If you’ve ever received a higher invoice than expected or had your freight delayed or rejected, this might be why.

Here’s what’s really going on, and what to do about it.

What Is Freight Reclassification?

Freight class is a rating between 50 and 500 that carriers use to price LTL shipments. It’s based on density, handling, stowability, and liability.

If your class is off — even slightly — the carrier can remeasure and reweigh the shipment and reclass it. That often means you pay more.

Common Reasons for Reclassification

1. Incorrect Weight or Dimensions

Carriers use dimensioners and certified scales. If you underestimate weight or size, they’ll reweigh it — and charge you the difference.

→ Fix: Always use accurate, final packaged dimensions and weight. Round up.

2. Wrong NMFC Code

Freight class is tied to NMFC (National Motor Freight Classification) codes. Some products have multiple possible codes depending on packaging or use.

→ Fix: Double-check with your broker or carrier if you’re unsure which NMFC code to use.

3. Low Density

If your shipment takes up space but doesn’t weigh much, it’ll get bumped to a higher class. Density is a huge factor in LTL pricing.

→ Fix: Know your pounds per cubic foot (PCF). [PCF = weight ÷ (length x width x height ÷ 1728)]

4. Packaging Issues

Odd shapes, loose items, or freight that can’t be stacked may not fit well in a truck. That increases handling difficulty and risk.

→ Fix: Use standard pallets when possible. Shrink wrap securely. Avoid overhang.

How to Avoid Freight Reclass Charges

  • Measure after packing, not before
  • Use a freight class calculator or ask your broker
  • Document everything — photos, weight slips, pallet counts
  • Include the correct NMFC on the BOL
  • Keep packaging consistent for repeat lanes

Final Thoughts

Reclass fees add up fast. They also damage your relationship with carriers.

If you’re regularly getting reclassed, it’s worth fixing — not just for your bottom line, but for better service overall.
