Your freight bill

Why is my freight bill higher than my quote?

The short answer

Freight Benchmarks found that 43.6% of 8,298 US import container shipments first invoiced July 2024 to June 2026 paid at least one extra charge, such as demurrage, storage, a chassis split or chassis extra days. Across all shipments, including those that paid none, extras averaged $174 per shipment. They are billed after the box lands, for things a quote can't know yet.

What a quote covers, and what it can’t

A typical import quote prices the ocean freight from the origin port, often with customs clearance and delivery to your door. Those costs are known when the quote is written. What happens after the container is unloaded is not: how many days it sits in the terminal, whether a chassis is waiting where the container is, whether customs picks it for an exam, and how long the driver waits at the gate or at your dock. Each of those becomes a line on a later invoice.

A careful quote can’t price those events in advance, but it can state the rules that will price them: the free time, the chassis days included, and the rate for each extra. When a quote says nothing about them, the first time you see the rate is on the bill.

The charges that show up after arrival

Here is how often the common extras were billed across all published ports in Freight Benchmarks’ data. Trucking fees are shares of shipments whose final trucking was billed on the same invoices.

  • Chassis extra days: 37.5% of trucked shipments, for days on a chassis beyond those included in the trucking rate. See chassis extra days.
  • Chassis splits: 29.0% of trucked shipments, when the trucker had to fetch the chassis from somewhere other than the container. See chassis split.
  • Storage: 9.5% of all shipments, at a terminal, a warehouse or the trucker’s yard. See storage.
  • Per diem and demurrage: 3.7% and 2.4% of all shipments, and when demurrage was charged the median bill was $490 per shipment. See demurrage and per diem.

Why the bill arrives in pieces

Freight, customs and delivery are usually invoiced as the shipment moves. Delay charges can’t be invoiced until they stop running: demurrage when the container leaves the terminal, per diem when the empty is returned, storage when the cargo is picked up. So a second or third invoice can follow the first by weeks, and it is often the bigger surprise. More on that in why a demurrage bill can arrive weeks after delivery.

A fair extra charge, or padding?

A fair extra charge has three things: a cause you can see, such as the dates, the hold or the wait; a rate that was agreed or published; and backup from whoever billed it first. Compare each amount with the benchmarks for your port. The port pages show how often each fee hits there and what it cost. An amount far above the usual range isn’t proof of overcharging, but it is a fair reason to ask questions, as covered in is my freight forwarder overcharging me?

What to do

  1. Before you book, get the terminal free time, the chassis days included in the trucking rate, and the rates for storage, chassis splits and driver waiting time in writing.
  2. When an extra charge arrives, ask for the carrier’s, terminal’s or trucker’s own invoice behind it. A pass-through charge should match it.
  3. Compare each amount with what other importers paid at your port on the port pages, or check a fee on your bill.
  4. For demurrage and detention, check the invoice against the FMC’s billing rule: see how to dispute a demurrage or detention invoice.

Questions

Is it normal for the final freight invoice to be higher than the quote?

It is common. In Freight Benchmarks' invoice data, 43.6% of US import container shipments paid at least one extra charge, such as storage, demurrage or chassis extra days. A quote can't price days that haven't happened yet, but it can state the free time and the rates that will apply.

What is an accessorial charge?

Any charge beyond the base freight and delivery rate: chassis extra days, chassis splits, storage, demurrage, per diem, customs exam costs, driver waiting time, overweight fees and similar lines. Freight Benchmarks measures how often each one is billed and what it costs, by port.

How much should I budget for extra charges on an import container?

Freight Benchmarks found that accessorial charges averaged $174 per shipment across all US import container shipments, counting the ones that paid none. The average hides a long tail: when demurrage was charged, 1 in 10 bills was over $2,870. Budget by port, and keep a margin for delays.

Can a forwarder add charges that weren't in the quote?

Usually only charges the quote or its terms allow, such as pass-through fees from carriers, terminals and truckers when they occur. Ask for the underlying invoice for each one, and ask whether pass-through charges are billed at cost or with a handling fee.
