How much should I pay to ship a 20ft container, and what the index will not tell you
There is no single answer, and the honest version has three parts. The published indices quote a 40-foot container — Drewry assessed its composite at $4,374 on 07/23/2026, down 4% on the week — and a 20-foot box is not half of that, because the cost of moving a slot is not proportional to what is in it. On top of the ocean line comes roughly 30% more in handling, federal fees and destination charges for a full container. And your quote sits above a composite more often than below it.
Why the 20ft price is not half the 40ft price
A vessel sells slots, and a slot is a unit of deck and stack space rather than a unit of volume. A 20-foot box occupies roughly half the length of a 40-foot box but consumes a comparable share of the handling, documentation and gate work at each end. On many lanes the 20-foot rate lands between 70% and 90% of the 40-foot rate, and on some it is higher per unit than the larger box.
The practical consequence: if your volume is near the boundary, price both. The larger box is frequently cheaper per cubic metre and occasionally cheaper outright.
The 20-foot decision, in three numbers
Three figures settle whether the smaller box is the right buy, and none of them is the headline rate.
| Question | The number | What it means |
|---|---|---|
| What fits | ~33 CBM usable in a 20ft, ~67 in a 40ft | Practical loading rarely reaches either |
| What it costs per unit | 20ft commonly 70-90% of the 40ft rate | The larger box is usually cheaper per CBM |
| What rides on top | ~30% of the delivered total | Handling and federal fees, not the freight |
Ocean freight is around 70% of the delivered total on a full container, so a $4,000 ocean line implies roughly $1,700 more before duty. The full itemisation of that 30% — terminal handling, brokerage, ISF, documentation, chassis and the two federal fees — is set out under what a 40-foot container actually costs delivered. Duty sits outside all of it and has no average.
How to read a published index without being misled
An index composite averages many shippers, many volumes and many contract positions on a route. Three things follow. A small shipper's quote sits above the composite more often than below. The index moves weekly, so a print without its assessment date is unreadable. And different publishers measure different things: Drewry and Freightos publish spot composites, Xeneta publishes contracted alongside spot, and none of them is your quote.
Read the index as context for whether the market is rising or falling, then get two quotes normalised to the same scope and compare those.
What a fair quote looks like on paper
- The ocean rate, with the port pair and the week it
is valid for.
- The surcharges named individually — THC, BAF, PSS, ISPS — rather than folded into "all-in".
- The exclusions listed, especially the destination side.
- Free time stated in days, and what the daily rate is after it. At most US terminals free time is
3 to 7 days and published demurrage runs $75 to $300 per container per day.
Where this goes next
Three pages carry the rest of this question: the number behind it, the comparison of whoever would do it, and the check that runs before you pay.
- the arithmetic of the total, duty and federal fees included — the figure behind it
- how the forwarder lists are built, and on what data — who does it
- the two-minute check that runs before you pay — check the licence
Two neighbouring pieces sit closer to this one than any of them: What are the top freight companies in the US, and Who is the No. 1 container company.
Frequently asked questions
How much should I pay for a 20 ft shipping container?
There is no single figure. Drewry assessed a 40-foot box on its composite at $4,374 on 07/23/2026; a 20-foot container commonly lands at 70-90% of the 40-foot rate, and handling plus federal fees add roughly 30% on top for a full container.
Is a 40ft container cheaper than a 20ft?
Per cubic metre, usually yes, and occasionally cheaper outright. If your volume is near the boundary, price both rather than assuming the smaller box is the cheaper booking.
Why is my quote higher than the index?
An index is a composite across many shippers and volumes. Small shippers sit above it more often than below, and the composite excludes the destination-side lines your invoice will carry.
How long is a container quote valid?
Spot rates reprice weekly, so a validity window is part of the price. A quote without an expiry date is not a rate you can plan on.
What is not in the ocean rate?
Terminal handling at $138-340 per end, brokerage at $100-250, ISF at $35-100, documentation, chassis, the two federal fees and duty. On a full container these are around 30% of the delivered total.
