Carrier reclassification and reweigh charges are some of the most common — and most disputable — surprises on an LTL invoice. Answer seven quick questions about how you build and document your shipments to see your reclassification risk score and exactly where you're exposed.
Guidance only. This score is a self-assessment of common reclassification triggers, not a carrier decision. Your actual exposure depends on your carrier, commodity, and NMFC classification.

A reclassification happens when a carrier inspects your shipment, decides the freight class on your bill of lading is wrong, and rebills at a higher class — usually with a reweigh or reinspection fee on top. The most common trigger is a density mismatch: the actual pounds per cubic foot don't match the class you declared, because the dimensions or weight on the BOL were estimated, rounded, or simply wrong.
Measure and weigh every shipment on a calibrated scale, put the exact dimensions and weight on the BOL, and calculate your real density before you assign a class. When your density lands near a break point, document it carefully — that's where disputes are won or lost. And when a carrier does reclass you, you can challenge it: if your documented density supports your original class, the burden is on the carrier to prove otherwise.
The carrier inspected the shipment, determined the freight class on your BOL was incorrect, and rebilled it at a different (usually higher) class — often with a reweigh or reinspection fee added.
A density mismatch from inaccurate dimensions or weight on the bill of lading. Most density-based class corrections trace back to estimated or rounded measurements.
Yes. If your documented dimensions, weight, and calculated density support your original class, you can dispute the rebill. The carrier should be able to show the inspection evidence (a reweigh ticket or inspection photos); if they can't, the charge is challengeable.

Weigh and measure every shipment accurately, calculate your true density, and put exact figures on the BOL. Pay special attention when your density is close to a class break point, and keep your NMFC classification current.
It weights seven common reclassification triggers — BOL accuracy, density type, proximity to a class break, packaging consistency, adjustment history, and classification currency — into a 0–100 score. It's a self-assessment, not a carrier ruling.
