The quote said one number. The invoice says another. Between them sit six or seven line items with names like “dry run,” “chassis split,” and “detention at delivery,” and there is no obvious way to tell which are legitimate and which you could have avoided.

This is a plain-English tour of the accessorials that actually show up on a container drayage invoice, what triggers each one, and whether you can do anything about it.

First: what an accessorial is

The base drayage rate covers the expected move — pick the container up, drive it to the delivery address, return the empty. An accessorial is anything that falls outside that expected move. Extra time, extra trips, extra equipment, extra storage.

Accessorials are not inherently a rip-off. Most of them represent a truck and a driver doing work that was not in the plan. The problem is when they show up unexplained, which is a communication failure rather than a pricing one.

The accessorials you will actually see

Chassis split

The chassis is not at the terminal where the container is, so the driver makes a separate trip to get it. Very common in South Florida. Avoidable by using an asset-based carrier with its own equipment — full detail in our guide to chassis splits.

Waiting time / detention at stop

The driver arrives at your warehouse and waits. Most carriers include a free window — often an hour or two — and bill by the hour after that. This is the single most controllable accessorial on the list. It is entirely a function of how fast your receiving dock works.

Dry run / trouble ticket

The driver goes to the terminal and cannot get the container: it is on hold, not yet available, the appointment was invalid, or the terminal turned the truck away. The trip happened and gets billed even though nothing moved.

Pre-pull

Pulling the container out of the terminal before your delivery date and staging it on the carrier’s yard. It bills as a separate move plus storage — but it is often cheaper than demurrage. See what is a container pre-pull.

Yard storage / ground rent

Daily charge for the container sitting on the carrier’s yard. Usually far cheaper per day than terminal demurrage or steamship line detention, which is the whole point of yard storage.

Overweight / tri-axle surcharge

Specialized chassis and permits for heavy containers. Covered in overweight container drayage in Florida.

Reefer / genset

Refrigerated containers need a powered genset on the road and monitoring at the yard. That is equipment cost plus fuel plus attention.

Hazmat

Placarding, certified drivers, restricted routing, and additional insurance. Not optional and not negotiable.

Empty return / second return attempt

If the return depot is full or refuses the box, the driver comes back another day. Two trips, two bills — and the per diem clock keeps ticking in the meantime.

Congestion or terminal surcharge

Applied when terminal turn times blow out and each container consumes far more driver time than normal. Usually temporary and usually announced.

Fuel surcharge

A percentage tied to diesel prices. Standard across freight, adjusts with the market.

Redelivery / reconsignment

The delivery address changes after dispatch, or the receiver refuses the load. The truck has to go somewhere else.

How to read a quote so the invoice isn’t a surprise

The best defence is a quote that names its assumptions. A quote that says only “PortMiami to Medley — $X” is telling you almost nothing. A useful quote states:

• How much free waiting time is included at pickup and delivery
• Whether a chassis split is anticipated for that steamship line
• The daily yard storage rate, in case you need it
• The dry run rate
• Whether the price assumes a standard dry container of a given weight

Ask for those five before you book. A carrier that can answer immediately has a real rate structure. Go Drayage publishes indicative South Florida rates and you can request a drayage quote with your specific details.

The four accessorials most within your control

Waiting time — unload faster, or transload instead of live-unloading. This is pure warehouse throughput.

Dry runs — verify the container is actually available and free of holds before dispatch, not just discharged.

Empty return failures — confirm the depot is accepting that line’s equipment before the truck rolls.

Storage stacking — decide early whether the box is going to your warehouse or to a yard. Indecision is what generates simultaneous demurrage, detention, and storage on the same container.

The bigger picture

If accessorials are a large share of your total drayage spend, the base rate is not your problem. Chasing a lower per-move rate while bleeding waiting time and dry runs is optimizing the wrong number. Fix the operational causes first, then negotiate. Our comparison of contract vs. spot drayage rates covers when locking in a base rate actually helps.

Frequently asked questions

Are drayage accessorial charges negotiable?

Some are. Free waiting time windows, yard storage rates, and fuel surcharge formulas are commonly negotiated on volume. Charges that reflect a genuine second trip, such as chassis splits and dry runs, are harder to negotiate away because the cost is real — the better play is to reduce how often they happen.

Why does my drayage invoice have more line items than my quote?

Because the quote priced the expected move and the invoice reflects what actually happened. That gap should be explained, not just billed. Ask your carrier to identify the trigger for each accessorial with a timestamp or gate receipt.

Which accessorial costs importers the most?

It varies, but waiting time and storage-related charges are usually the largest avoidable categories, because they accrue by the hour or by the day rather than as a one-time fee. They are also the two most influenced by your own operations.
