What a W&I re-bill is
Weight and inspection (W&I) is the carrier's check of what you declared on the bill of lading against what actually crossed its dock. At most large LTL terminals that check is done by overhead or drive-through dimensioners, laser or camera systems that measure a pallet in seconds as a forklift carries it through, and by certified floor or forklift scales. When the measured dimensions, weight or commodity differ from the bill, the carrier issues a corrected invoice, usually with an inspection certificate or report attached.
A re-bill can change four things: the weight, the dimensions (and so the density and class), the commodity description (and so the NMFC item), or the application of a rules tariff item such as a cubic capacity or linear foot charge. Many carriers also add an inspection or correction fee. Each of those is a separate question in a dispute, and it pays to separate them before writing anything.
Dimensioners used for billing are commonly certified as legal for trade under the U.S. National Type Evaluation Program, which means they are accurate within published tolerances when installed and maintained correctly. They measure what they see: stretch wrap tails, banding buckles, a tilted top carton and forklift tines can all register. That is where most winnable disputes come from.
Worked example: is this re-bill worth fighting?
A shipper's bill shows four stackable 48 × 40 × 48 pallets at 450 lbs each, class 100. The carrier's W&I report shows 50 × 42 × 52 inches and reclasses the freight to class 125.
| Scenario | Dimensions | Total cube | Density | Class | Indicative bill, 850 mi |
|---|---|---|---|---|---|
| Shipper's BOL | 48 × 40 × 48 | 213.3 cu ft | 8.44 PCF | 100 | $301 |
| Carrier W&I report | 50 × 42 × 52 | 252.8 cu ft | 7.12 PCF | 125 | $376 |
| Overhang real, height wrong | 50 × 42 × 48 | 233.3 cu ft | 7.71 PCF | 125 | $376 |
| Height wrong only (another load) | 48 × 40 × 56 read, 48 true | 248.9 vs 213.3 | 7.23 vs 8.44 | 125 vs 100 | $376 vs $301 |
The math for the carrier's reading: 50 × 42 × 52 ÷ 1,728 = 63.19 cubic feet per pallet, 252.8 for four; 1,800 ÷ 252.8 = 7.12 PCF. Now suppose the shipper's photos prove the pallets were 48 inches tall, but the cartons did overhang the deck by an inch on each side. The true dimensions are 50 × 42 × 48: 58.33 cubic feet each, 233.3 total, 7.71 PCF. Still class 125. Winning the height argument would not change the bill by a cent, because the overhang alone moved the freight across 8 PCF.
The fourth row is the dispute worth filing: a load whose true footprint matched the bill, read 8 inches tall because of a stretch wrap tail or a forklift carrying the pallet tilted. There the correction is the difference between class 125 and class 100. The first test in every dispute is the same: recompute the class with your best true dimensions, and only argue the numbers that change it.
Re-run the carrier's dimensions
- Safe — tariff cube, density and linear feet stay under the carrier's cube and linear-foot rules.
- Tier 1 — 350 cu ft or more under 3 PCF (XPO, Saia, ABF, Estes): synthetic weight of 6 lbs per tariff cubic foot.
- Re-bill — 750 cu ft or more under 6 PCF, or linear feet at the carrier's rule: book volume LTL or direct partial truckload.
The dispute procedure, step by step
- Log the re-bill the day it arrives. Record the PRO number, BOL number, ship date, invoice date, original and corrected charges, and the reason code. Federal law (49 U.S.C. 13710) gives a shipper 180 days from receipt of a bill to contest the charges, but carriers resolve disputes faster and more favourably when they are filed within days, and your pricing agreement may set its own process.
- Request the inspection record. Ask for the W&I certificate or inspection report, dimensioner images, the terminal and date of inspection, the scale ticket if weight changed, and the device's certification details if you intend to challenge the measurement itself.
- Pull your own evidence. The signed BOL, the pick and pack record, photos of each pallet with a tape measure visible on length, width and height, the scale ticket from your floor scale, and your packaging specification if the product ships the same way every time.
- Recompute both versions. Run your true dimensions and weight, then the carrier's, through the cubic feet calculator. Note the density, class, tariff cube and whether a cube or linear rule applies in each. If your true numbers produce the same class and charge as the carrier's, do not dispute the class; at most dispute the fee.
- Identify the single cause. Height read high from wrap or straps, footprint read wide from a tilted pallet, weight including forklift attachments, commodity misread, imputation applied to a stackable unit. One clear cause, shown in one photo, wins more often than a list of five.
- Write the dispute. One page: PRO and BOL numbers, what was declared, what was billed, what was true and why, the corrected class and charge you are asking for, and the attachments. State the math explicitly so the reviewer can check it in a minute.
- Submit through the carrier's dispute or invoice-correction channel and keep the confirmation. If you ship through a broker, send it to the broker; they file with the carrier and track it.
- Follow up on a schedule. Check status at about 10 and 30 days. If the dispute is declined, ask for the specific reason and decide whether new evidence exists. Escalate patterns, not single bills, to your carrier account representative.
- Fix the cause for next time. Update the packaging spec, the BOL template or the stacking label so the same correction does not recur.
What wins and what does not
| Argument | Usually | Why |
|---|---|---|
| Photo with tape measure shows true height lower than read | Wins | Direct evidence of a measurement artefact |
| Scale ticket from a certified scale shows lower weight | Often wins | Two certified readings; carrier may re-scale |
| Unit was stackable but was cubed to 96 in | Often wins | If the unit had a flat, rigid top and no do-not-stack label |
| "Our BOL said class 100" | Loses | The class on the bill is a declaration, not evidence |
| "We always ship it this way" | Loses | Past bills that were never inspected prove nothing |
| Overhang was "only an inch" | Loses | Dimensions are taken at the extreme points |
| Dimensions disputed but class unchanged | Wastes time | No change to the charge |
Preventing the next one at the dock
Most re-bills are prevented, not won. The habits that work:
- Measure every pallet after wrapping, at the extreme points, pallet deck included, and round up to the next whole inch.
- Weigh after wrapping on a scale that is checked regularly, and record gross weight per line.
- Photograph each pallet with a tape measure in frame on two sides and the top; keep the photos with the BOL for at least the dispute window.
- Tuck stretch wrap tails, cut excess banding, and keep top tiers level.
- Put the dimensions on the pallet label as well as the bill so the terminal sees them.
- Label do-not-stack only when it is true. A flat-topped stackable pallet labelled do-not-stack invites a 96-inch imputation.
The full routine is on the BOL dimensional checklist, and the overhang numbers are on the overhang guide.
When the re-bill is really a mode problem
Some re-bills are correct and will keep coming: tall, light, non-stackable freight that crosses cube thresholds every time it ships. Disputing those wastes staff time. If the same lanes produce cube or linear-foot corrections month after month, the shipments belong on a spot volume quote or a direct partial truckload priced on linear feet and weight, where there is no dimensioner re-bill to dispute. Send a sample of recent corrected invoices with dimensions to rates@cubictransport.com and we will price the same loads on those modes, or request a quote through the tender form.
