Customs Broker Overcharges: How to Spot Them
Overcharges on a customs broker invoice rarely look like errors. This guide covers the common types, how to catch them, and how the right tool surfaces them automatically.
A customs broker invoice mixes pass-through government charges with the broker's own service fees, and that blend is exactly where overcharges hide. Most aren't dramatic — a fee charged twice, a service marked up beyond what was agreed, an amount that doesn't match the math. Individually they're small; across many shipments they add up. This guide explains the common overcharge types and how to surface them.
Common overcharge types
Overcharges tend to fall into a handful of recurring patterns. Knowing them makes them far easier to catch.
- Duplicate fees
- The same service billed more than once — for example, a document or handling fee that appears on two lines under slightly different labels.
- Marked-up pass-through charges
- Government charges your broker pays on your behalf, billed back at more than the actual amount paid to CBP.
- Inflated service fees
- A brokerage service charged above the rate you agreed to, or above the broker's own published fee.
- Fees for services not rendered
- Line items for handling, exams, or processing that didn't actually apply to your shipment.
- Math and rounding errors
- Totals that don't match the sum of the lines, or per-line amounts that don't reconcile against the figures they're based on.
How to spot overcharges
- 1
Separate pass-through from service fees
Split the invoice into government charges and the broker's own fees. Overcharges usually hide in one of those two buckets, and confusing them is what lets charges slip by.
- 2
Recalculate what you can
Re-derive the amounts that follow fixed rules from the declared figures, and compare your result to what was billed.
- 3
Compare against what you agreed
Check service fees against your rate agreement, not just against the invoice itself.
- 4
Look for repeats and mislabels
Scan for the same charge appearing twice under different names — a common, easy-to-miss pattern.
Broker Inspector reads your uploaded invoice with AI, then verifies the broker's charges against the charges it calculates as expected — using the official HTSUS and CBP fee schedules as references. Where a charge exceeds the expected amount, it's flagged as a potential overcharge in the verdict, so you can see exactly which lines to question. The result is exportable as a PDF or CSV.
