LTL reweigh and reclassification
A reweigh is when the carrier weighs your shipment and bills a different weight from the one on the bill of lading. A reclassification is when the carrier bills a different freight class. Either can raise the invoice above the quote, and either is easier to review if you kept your own measurements.
Why carriers reweigh and inspect
Carriers can inspect shipments to confirm they match the bill of lading. One carrier's rules tariff, for example, says every shipment it handles is subject to inspection (XPO, Tariff CNWY 199, Item 26). The same tariff says that a bill of lading whose commodity description is too vague to classify may be billed at class 150 and inspected (Item 26), and that a reweigh showing 25 lb or more above the stated weight brings a reweigh fee and recalculated charges (Item 239). Other carriers set different rules and thresholds.
Why dimensions matter
NMFTA's changes to the National Motor Freight Classification, which took effect on July 19, 2025, expanded the density scale used for density-based classifications. When a classification depends on density, the dimensions the carrier measures affect the class it bills. Density alone does not decide every class; see freight density vs. freight class.
Evidence to keep before the shipment leaves
- A photo of each piece with the tape measure visible.
- A scale ticket or another weight record.
- Measurements taken after wrapping and banding.
- A copy of the bill of lading, with a complete commodity description.
The shipment measurement sheet records all of this on one page.
If you receive a reweigh or a reclassification
- Ask the carrier for the record behind the change, such as the weight or inspection record.
- Compare it with your own measurements and with the bill of lading.
- Expect to need documents to correct a bill of lading. One carrier's tariff, for example, only accepts changes to weight, class or description with documentary proof that supports them (XPO, Tariff CNWY 199, Item 205).
- Time limits apply to contesting a bill. See how to compare an LTL invoice with your quote.
