For many U.S. businesses, LTL (Less-Than-Truckload) shipping looks simple until unexpected reweighs alter the final invoice.
When carriers perform these reweighs, they often find discrepancies that lead to significant price adjustments. This is especially after your freight has already left the dock.
You book a shipment, provide the weight, and expect the quoted rate to be the final word.
Except it rarely ends there.
Weeks later, a second invoice shows up with a total much higher than expected.
The reason is often buried in a few words that quietly drain profit. LTL reweighs.
These fees are one of the most common and least understood cost drivers in the logistics industry.
For companies that ship LTL regularly, these small “corrections” can evolve into a significant annual loss.
Why Does Weight Accuracy Matters in the LTL Logistics?
To solve the problem, we must first understand the carrier’s perspective.
Unlike full truckload shipping, where you rent the entire trailer, LTL shipping is a shared economy.
Multiple shippers occupy the same space.
So, carriers rely on shipper-provided data, such as weight, dimensions, and freight class, to solve a complex daily puzzle.
They must balance trailers to meet Department of Transportation (DOT) safety regulations.
They must plan terminal stops to maximize efficiency.
When a shipper provides an inaccurate weight, it doesn’t just affect one invoice.
What happens is that it throws off the weight distribution of the entire vehicle.
Because the LTL model operates on thin margins, carriers have become incredibly efficient at catching these errors.
How Do Carriers Catch Weighing Errors?
Gone are the days when a dock worker might glance at a pallet and guess its weight.
Today, LTL carriers use advanced technology at their break-bulk terminals to audit almost every shipment.
Certified Forklift Scales
Most forklifts in modern terminals are equipped with scales that weigh the freight the moment it is lifted.
Dimensioning Systems
These are laser-based sensors that scan a pallet in seconds. They capture the exact length, width, height, and weight simultaneously.
Automated Flagging
If the captured data differs from your Bill of Lading (BOL), the system automatically triggers a re-rating of the shipment.
Why Do ReWeighs Cost More Than You Think?
Many shippers assume reweighs simply means paying for the “extra” pounds.
In reality, a re-weigh fee is the tip of the iceberg.
The true cost is often a compound effect.
1. The Weight Correction
This is the most direct cost. If you quoted 1,000 lbs but the carrier measured 1,200 lbs, you will be billed for those extra 200 lbs at your current rate.
2. The Administrative Fee
Most carriers charge a flat “Weight & Inspection” (W&I) fee just for the labor involved in correcting your paperwork. This fee typically ranges from $25 to $50 per occurrence.
3. Reclassification (The Profit Killer)
This is where the real damage happens. LTL rates are heavily influenced by density (weight divided by volume). If your weight changes, your density changes.
And when your density changes, your Freight Class may change.
Moving from a Class 70 to a Class 100 can increase your base rate by 20% to 40%.
Suddenly, a small weight error has turned into a massive billing adjustment that wipes out the margin on the product you just shipped.
4. Loss of Trust and “Account Flagging”
Carriers keep data on every shipper. If your account consistently shows a 15% discrepancy between your BOL and actual weights, you become a “high-risk” shipper.
Carriers may respond by:
- Increasing your base rates during contract negotiations.
- Applying stricter inspection protocols to your shipments.
- Reducing your “Freight All Kinds” (FAK) allowances.
What Are Common (and Costly) Gaps in the Warehouse?
Most weight errors are not intentional. They are the result of small process gaps that accumulate over time.
To fix the problem, you have to look at the loading dock.
The “Estimated” Weight Trap
Many warehouses use the weight listed in their sales catalog. However, catalogs often list the “net weight” of the product, failing to account for the “gross weight” of the final shipping unit.
The Pallet and Packaging Factor
A standard wooden pallet weighs between 30 and 50 lbs. Heavy-duty crates, shrink wrap, corner protectors, and dunnage can add another 20 lbs.
If you ship 10 pallets and forget to include the packaging weight, you are already off by 500 lbs.
Equipment Calibration
Scales that aren’t calibrated annually can slowly drift.
A scale that is off by just 2% can cost a high-volume shipper thousands of dollars over a year.
What Is A Strategic Roadmap to Eliminating Fees?
Reducing LTL re-weigh fees is about discipline, not negotiation. Here is how smart shippers take control:
Step 1: Weigh the “Final” Unit
Never rely on pre-packaging weights. The only weight that matters is the one the driver feels when they lift the pallet.
Invest in a floor scale or a pallet jack scale and make it a mandatory step to record the weight after the pallet is wrapped and ready.
Step 2: Update Your Master Data
Conduct a “packaging audit.” Weigh your top-selling items in their final shipping configurations.
Update your ERP or Warehouse Management System (WMS) so that the “Gross Weight” is automatically calculated when a BOL is generated.
Step 3: Document Everything
When you dispute a re-weigh fee, the burden of proof is on you. Take a photo of the pallet on your scale with the weight visible.
This “digital proof” makes it much easier for a partner like Jansson to successfully dispute an incorrect carrier measurement.
