QUICK ANSWER A chassis fee is the daily rental for the wheeled frame that carries an ocean container on the road, commonly $25 to $45 per day and higher in tight markets. Around that base sit its relatives: the split fee when the frame and the box start in different places, the flip fee when a terminal moves a container between frames, and tri-axle premiums for overweight loads. The days count automatically from pickup to return, whether anyone watches them or not.
No line on a drayage invoice confuses importers like the chassis fee, because nobody remembers renting one. The frame appears under the container at the terminal and the meter starts. Here is the whole fee family, why the system works this way, and where the days pile up unnoticed.
A wheeled frame you rent by the day
A chassis is the skeletal trailer, wheels, frame, brakes, lights, that an ocean container locks onto for its drayage leg. Containers cannot roll; every box that leaves a terminal by truck rents a frame, and the rental is priced per calendar day, commonly $25 to $45. The fee itself is small. What surprises people is the multiplication: a container that gates out Monday, unloads Thursday, and returns empty the following Tuesday has paid for eight days of frame, a rental that can approach the price of the move itself.
A short history of the rented frame
The US system is an accident of history. Ocean carriers owned chassis for decades and handed them out with the container, until they exited the business in the years after 2009, dumping the fleets into pool operators and leasing companies. Today most frames belong to intermodal equipment providers running shared pools at the ports, some to trucking companies, and almost none to the carriers whose containers ride them. Every chassis fee on your invoice descends from that separation: someone owns the box, someone else owns the wheels, and you pay the second party by the day.
The whole chassis fee family
Chassis charges and what triggers each
| Charge | What triggers it | Typical shape |
|---|---|---|
| Daily rental | Every day from gate-out to return | $25 to $45 per day, market dependent |
| Split fee | Chassis and container start in different locations | Commonly $50 to $150 per event |
| Flip fee | Terminal lifts a container from one frame to another | $25 to $100 |
| Tri-axle premium | Cargo over road-legal weight for a standard frame | Per move, equipment and permit dependent |
| Late return / pool fee | Frame kept past the pool's terms | Flat or escalating daily, pool dependent |
TAKEAWAY The days count themselves; nobody at the pool calls to warn you. Ask for chassis days as a line on every drayage invoice, and treat more than three or four days on a routine delivery as a question worth asking.
The split fee, dissected
A split happens when the frame is not where the box is. The driver first deadheads to a chassis depot, mounts a frame, then drives to the terminal for the container: two stops, extra miles, extra time, billed as a split fee of commonly $50 to $150. Splits multiply when pools run dry at peak and when a carrier has no committed frames at that port. They fall close to zero when the trucker controls its own chassis or the pool sits inside the terminal, which is a fair question to ask any drayage provider before peak season: where do your frames live?
Weight and the tri-axle premium
Standard frames carry standard loads. Past roughly 36,000 pounds of cargo in a 20-foot container or 44,000 in a 40-footer, the move needs a tri-axle chassis to stay road-legal, plus permits, at a premium per move and with fewer trucks available to run it. The full weight math lives in our drayage explainer; the chassis-specific point is that the premium is predictable from the packing list, so discovering it at the gate is a planning failure, not bad luck.
Keeping chassis days down
The lever is turnaround. A live unload done inside the free hour returns the frame in a day or two. A drop-and-hook, where the trailer waits at the warehouse while the driver leaves, trades convenience for days of rental, sometimes worth it, never free. And the empty return is where chassis days and per-diem run on the same calendar: the frame and the box usually go back together, so a slow empty return bills you twice for the same delay. Counting the days on each container is what makes the pattern visible; monthly totals hide it.
How Platton manages chassis exposure
Chassis costs respond to arrangement more than negotiation, and the arrangement is set before the vessel arrives.
Carriers with committed chassis access
Our drayage carriers run committed chassis arrangements at their ports, which keeps split events the exception. Where a pool is known to run tight in peak, the plan accounts for it instead of discovering it.
Days counted per container, on the quote
Chassis days appear in the all-in quote and on the invoice as a counted line, so an eight-day rental on a two-day delivery stands out immediately and gets fixed on the next container.
Weight flagged before the gate
Packing list weights get checked against the tri-axle thresholds when the shipment is booked, so overweight moves get the right equipment booked from the start.

Common Questions About Chassis Fees
How much is a chassis fee per day?
Most markets run $25 to $45 per day, with tight ones reaching $50 or more. The rate matters less than the day count: at $35 a day, the difference between a two-day and an eight-day cycle is $210 per container, every container, so the count belongs on the invoice.
What is a chassis split fee?
A charge, most invoices show $50 to $150, billed when the chassis and the container are in different places and the driver must make a separate trip to fetch the frame before picking up the box. It prices the extra stop and miles. Carriers with committed or terminal-based chassis rarely bill it.
Is a chassis surcharge the same as a chassis fee?
Yes. Chassis fee, chassis usage fee, chassis surcharge, and chassis rental all name the same daily charge for the frame; the wording varies by who bills it, carrier, pool, or trucker. If two chassis lines appear on one invoice, that is worth a question, not a synonym.
What is chassis demurrage?
The charge for keeping a frame past the pool's allowed terms, flat or escalating depending on the pool, the chassis world's version of late equipment fees. It stacks on top of the ordinary daily rental and usually signals the same root problem: an empty return that did not happen on time.
How much does a container chassis weigh?
A standard 20-foot chassis weighs roughly 5,000 to 6,000 pounds, and 40-foot frames run somewhat heavier. That tare weight is part of why road-legal cargo limits sit well below a container's structural maximum: the truck, frame, and box eat into the 80,000-pound federal gross before the first carton counts.
Who owns the chassis pools?
Mostly intermodal equipment providers, leasing companies running shared pools at ports and ramps, plus trucking companies with their own fleets. Ocean carriers largely left the business years ago. Buying your own frames only makes sense at fleet scale, which is why virtually every importer rents by the day through the drayage carrier.
