THE PROBLEM
It's not the freight that kills your margin. It's the fees.
The base rate is the part you agreed to. Then come the surcharges. All of it shows on the invoice, weeks later, when it's too late to argue.
15-40%
of a parcel bill is now surcharges, not freight
$145
average overcharge on a corrected LTL shipment
4-6%
of shipments get flagged for a reweigh or reclass
70-82%
of disputed charges are recoverable, if you can prove your numbers in time

Carrier bills
16 lb
You measure with a tape and round to something clean. They use a certified scale and a dimensioner, measure to the fraction, and round up. They bill their number.
AND IT JUST GOT WORSE
The rules chang in the carrier's favor
12 July, 2026
USPS cut its dimensional divisor from 166 to 139, matching FedEx and UPS. Every fraction of an inch now rounds up.
A 12.2" side counts as 13"
3 sides rounded up adds up.
3 lb package that used to bill as 12 lb now bills as 14
It used to bill as 12. Big and light means you pay for size, not weight.
What's inside
5 plays to stop the oversize fees
Every threshold and dollar figure spelled out.

1. Audit the bill
Most shippers have never seen their surcharge spend in one place. How to run the audit, and how to trace it back to the SKUs and lanes causing it.
2. Measure before it ships
The carrier measures to the fraction and rounds up. How to match them at the dock, before the label prints, without a $50,000 dimensioner.
3. Kill the cheap triggers
Every trigger threshold in inches and pounds, with the fee attached, so you know which boxes are about to cost you.
4. Keep dated proof of measurement
You will still get flagged on 4 to 6% of shipments. What counts as proof a carrier accepts, and the filing window you cannot miss.
5. Take the data to the table
Prove your real dims and weights and you have leverage. The contract levers that move the bill, and what to put in front of your rep.

PROOF
One building cost 5 times its sister site.
Case study
At a medical-supply distributor, 1 of 5 warehouses sat on roughly 150 weight and inspection bills, five times its sister site. Once every scan saved a photo as proof, the surcharges dropped to almost 0.
~150 → ~0
W&I bills at the worst-performing site. The logistics manager hasn't had one from that building since.
