Reweigh and reclass audit: check every LTL weight and class change against your BOL
The Warp reweigh and reclass audit takes one shipment or a CSV of PROs, recomputes density from your dimensions, checks it against the density to class scale, and flags any reweigh or reclass charge that does not hold up.
How it works:Drop the carrier’s CSV or PDF, paste rows from Excel, or type one line. Check the column mapping, then read the findings in three tiers: dispute, review, note. Copy the letter.
What this audit catches
LTL carriers can reweigh or re-inspect a shipment at any point after pickup, and both actions can change the price. This audit checks a billed weight increase against whether a certified scale ticket backs it up, checks a small weight change against the tolerance your carrier typically allows before it should even bill a reweigh fee, and checks a class change against the density your own dimensions support. It also catches the two cheapest mistakes to miss: a reweigh or reclass fee billed when the weight or class never actually changed, and the same PRO billed twice.
None of this replaces your carrier’s tariff item, which sets the exact tolerance and evidence rules for your contract. It gives you the math to ask the right question before you pay.
How to run this audit
Pull the PRO number, the BOL weight and class, the billed weight and class, and the pallet dimensions from your invoice and BOL. Enter one shipment in the form for a quick check, or export a CSV from your TMS or accounting system with a row per PRO and upload it. Mark whether the carrier provided a certified scale ticket or inspection certificate for each shipment: those two fields decide whether a weight or class change is defensible.
Set the weight tolerance to match your carrier’s tariff item if you know it. The default of 10 pounds or 2 percent, whichever is larger, is a reasonable typical starting point but is not a universal rule.
How Warp bills instead
Warp LTL pricing is per pallet and all inclusive: no fuel surcharge, no accessorials, and no terminal handling added after the quote. Every Warp invoice is audited against its original quote before it ever reaches you, so a reweigh or reclass that changes your price after pickup is not something you have to catch yourself.
Reweigh and reclass audit FAQ
What is a reweigh and reclass audit?
A reweigh and reclass audit compares the weight and freight class a carrier billed against what your bill of lading originally stated. Carriers reweigh and re-inspect LTL shipments at their discretion, and a change in either number changes the price. This audit recomputes density from your shipment dimensions and checks it against the standard density to class scale, flags weight or class changes that lack supporting evidence, and finds reweigh or reclass fees billed with no actual change behind them.
How do carriers calculate freight class from density?
LTL carriers estimate freight class from density, measured in pounds per cubic foot. Density is total weight divided by cubic feet (length times width times height, in inches, times pallet count, divided by 1,728). The result maps to a class band on the 11 subclass density scale used across the industry: denser freight gets a lower, cheaper class, while lighter, bulkier freight gets a higher, more expensive class. Carriers publish the exact break points in their own NMFC tariff item, so treat the scale in this tool as typical and check your carrier item for the final word.
What is a reasonable weight tolerance before a carrier can rebill?
There is no single industry standard, and every carrier sets its own tolerance in its tariff item, but a flat floor of about 10 pounds or a small percent of the original BOL weight is typical for small variances from a scale reading. Anything inside that band is normal measurement variance, not a billable reweigh. This tool lets you set both numbers so you can match your carrier’s published tolerance.
What evidence should a carrier provide for a reweigh or reclass?
For a reweigh, ask for the certified scale ticket showing the date, PRO number, and actual weight. For a reclass, ask for the inspection certificate or photos documenting the commodity, along with the density calculation the carrier used. Without both, a reweigh or reclass charge is difficult for the carrier to defend if disputed, and you have grounds to push back.
Why would a carrier bill both a reweigh fee and a reclass fee on the same shipment?
Sometimes a single dock inspection turns up both a weight discrepancy and a class discrepancy, and both are legitimate. Other times the same inspection gets billed as two separate fees for what is really one event. Check that each fee has its own supporting evidence before accepting both.
Does Warp charge reweigh or reclass fees?
Warp LTL pricing is per pallet and all inclusive, with no fuel surcharge, no accessorials, and no terminal handling added after the quote. Every Warp invoice is audited against its original quote before it reaches you, so there is nothing to reconcile after the fact. See the full freight invoice audit for how that works across every charge type.
