Why Was My LTL Shipment Reclassified?
Short answer
Because the carrier found that the class, weight or description on the bill of lading did not match the freight. LTL rules tariffs let carriers open packages, reweigh shipments and check density; when the information is wrong, the freight bill is corrected and re-rated, and many carriers add an inspection or validation fee.
What it depends on
- Wrong NMFC item or class on the bill of lading.
- Lower density than declared, often from taller or overhanging pallets.
- A weight difference found on reweigh.
- A vague description that does not identify the commodity.
What carriers are allowed to check
Rules tariffs spell it out. FedEx Freight's tariff says that when bill of lading information "is incomplete or believed to be incorrect," the carrier will take the action needed to determine the correct information, including "opening of packages to inspect the contents," "verification of gross shipment weights" and "verification of actual or declared density." When the information is wrong, the freight bill is corrected and the increased weight is charged "at the highest rated commodity in the shipment."[1]
Many shipments are measured automatically. RXO notes that most shipments go through a dimensioner that scans pallets, and "if the dimensioner results vary from the listed product specifications on the bill of lading, the LTL carrier will reclassify the freight."[2]
What it costs
Beyond the re-rated freight charge, fees are common. The same FedEx tariff, effective January 5, 2026, lists a $40 validation fee when a reweigh finds the shipment 50 lb or more heavier, or when an inspection changes the charges.[1] Other carriers set their own amounts. A motor carrier must give you, on request, the rules and rates its charges are based on.[5]
How to prevent it
- Use the correct NMFC item for the commodity, and confirm its class with the carrier.
- Measure each handling unit at its greatest length, width and height, including the pallet and any overhang, as NMFTA describes.[3]
- Weigh the shipment as tendered, pallet included.
- Build pallets square and tight; overhang and tall, light stacks lower density.
- Photograph each pallet with a tape measure before pickup, in case you need to dispute.
Example
A pallet is declared as 48 x 40 x 48 in. and 600 lb: 53.3 cubic feet and 11.25 pcf, which falls in class 92.5 on the density scale. The carrier's dimensioner measures it at 60 in. tall because of a loose top layer: 66.7 cubic feet and 9.0 pcf, class 100.[4] If the item is classed by density, the shipment is re-rated at class 100 and a fee may apply.
Limitations
Whether density sets the class depends on the NMFC item. Tariff fees and procedures differ by carrier and change over time; the figures above are from one published tariff.
