Every importer who has moved a container through PortMiami has had the same experience: the drayage quote said one number, the invoice said another, and the gap was not small. This is usually not a case of being overcharged. It is that the quoted rate covers one specific scenario — a clean pickup, an available chassis, a container that leaves the terminal on the first attempt — and real freight does not always cooperate.
The Line Haul Is the Small Part
The base rate covers the truck moving from the terminal to your warehouse and back. Inside Miami-Dade that is a short run. Our facility in Doral sits roughly fifteen miles from PortMiami and about the same from Miami International Airport, so on a clean day the round trip is a couple of hours of driver time.
That is the number you get quoted, and on a good share of containers it is close to what you pay. Everything else lives in the accessorials.
Chassis: The Charge Nobody Budgets For
A container needs a chassis to move on the road, and at most US ports that chassis does not belong to the trucker. It comes from a pool and it bills by the day. If the container sits at your warehouse for three days while you unload, you are paying chassis rental for three days on top of the move itself.
Two situations make this materially worse. A chassis split means the container is at one terminal and the available chassis is somewhere else, so the driver makes an extra trip before he can even collect your freight. Scarcity is the other: when the pool runs short, day rates climb and appointment slots get harder to secure.
Waiting Time, Dry Runs, and Pre-Pulls
Drivers bill for time spent waiting at the terminal beyond an allowance, usually an hour or two. Terminal congestion is not your fault and it is not the trucker’s, but somebody pays for the hours.
A dry run is when the driver arrives and leaves empty — the container was not released, customs was not cleared, the appointment was wrong, or the box could not be located. You are billed for the attempt. A pre-pull is the deliberate version of the same idea: the container is collected before your free time expires and parked at a yard, so the terminal clock stops even though your warehouse is not ready. It costs money, and it is frequently cheaper than the alternative.
Weight, and Why It Matters More Here
A standard tractor-trailer has a legal limit on how much it can carry, and heavy containers exceed it. Moving one legally needs a triaxle chassis or an overweight permit, both of which cost more. Importers who load a forty-foot container to the ceiling with dense product routinely get surprised by this, and it is entirely avoidable at the point of loading.
How to Make the Bill Predictable
You cannot remove accessorials, but you can stop most of them from happening.
- Clear customs before the vessel arrives. Most dry runs trace back to a document that was not ready. Your broker can file in advance.
- Know your free time and count it correctly. It is set by your carrier contract, not by the port, and calendar days and working days are not the same thing.
- Book the unload before you book the truck. A container that arrives at a warehouse with no dock slot becomes a chassis rental.
- Ask about pre-pull early, not late. Once demurrage starts, the decision has already been made for you.
- Give your warehouse the packing list in advance. Knowing what is in the box determines how fast it comes out of it.
The importers who consistently pay close to their quoted rate are not getting better pricing. They are running a tighter process on the paperwork and the receiving end, so the expensive scenarios never get a chance to start.
If you are moving containers through PortMiami and want them unloaded close to the terminal rather than trucked across the county first, our crossdock and transload services are built around exactly that. Tell us what you are moving and we will tell you what it takes.
