Not every container that lands in Miami is staying in Miami. A large share of the boxes crossing PortMiami and Port Everglades are headed onward — to Kingston, San Juan, Santo Domingo, Panama, Colombia, and dozens of smaller Caribbean and Latin American destinations that South Florida has served as a gateway for decades.
Transshipment freight follows different rules than domestic import freight, and the drayage leg in the middle is where a lot of avoidable cost and delay accumulates.
Why South Florida became the gateway
Geography did most of the work. Miami sits closer to much of the Caribbean basin and the northern coast of South America than any other major U.S. container gateway, and the region built the supporting infrastructure around that advantage: consolidators, freight forwarders, NVOCCs, customs brokers, and a dense cluster of warehouses in Medley, Hialeah, and Doral that exist specifically to receive, consolidate, and re-export cargo.
The result is a market where a container can arrive from Asia or Europe, be broken down, recombined with cargo from three other sources, and depart on a feeder vessel south — sometimes within days.
The three common transshipment patterns
1. Pure transit (T&E)
The cargo enters the U.S. and leaves again without ever entering U.S. commerce, moving under a Transportation and Exportation in-bond entry. No U.S. duty is owed. The container is under Customs control the entire time, which means the trucking leg must be handled by a bonded carrier. Our overview of bonded container drayage in Miami covers what that requires.
2. Consolidation and re-export
Import containers are stripped at a container freight station, cargo is sorted by destination, and new export containers are built with mixed cargo for a single onward port. This is the workhorse pattern for Caribbean trade, where individual consignees rarely fill a container on their own.
3. Import, store, then export
Goods are entered, held locally, and shipped south as orders come in. Cash flow and inventory considerations often push importers toward a bonded warehouse or foreign trade zone arrangement rather than paying duty on goods that will leave again.
Where the drayage leg goes wrong
Missing the export receiving window
Every outbound vessel has an earliest receiving date and a cargo cutoff. Deliver too early and the terminal will not accept the container; deliver too late and the box rolls to the next sailing, which for smaller Caribbean services can mean a full week. Our post on export drayage and earliest receiving dates goes deeper on this.
Using a non-bonded carrier for in-bond freight
A trucking company that is not approved by U.S. Customs cannot legally move uncleared cargo. Discovering this on pickup day means finding a new carrier under time pressure.
Underestimating the turn time between import and export
Transshipment compresses two drayage moves, a strip, a sort, a re-stuff, and an export delivery into a short window. Each handoff between separate vendors adds a day. Consolidating those steps with one operator who has the yard, the equipment, and the bonded authority in one place removes most of the slack.
Ignoring the empty
The inbound ocean container still belongs to the inbound line and still accrues per diem while it sits waiting to be stripped. Fast turns are not just about the export deadline.
What to look for in a drayage partner for transshipment work
- Customs bonded authority. Go Drayage is licensed by U.S. Customs under bond number LBR8, which allows bonded moves in and out of our own facility rather than requiring a hand-off.
- On-site transloading. Stripping and re-stuffing at the same yard the container was drayed to eliminates an entire move. Our container freight station runs 19,000 and 40,000 lb forklifts for exactly this.
- Yard capacity for staging. Export consolidation needs somewhere to hold cargo while the rest of the shipment arrives. Five acres and roughly 450 container and trailer positions is a different proposition than a carrier with no yard.
- Both terminals. Inbound and outbound do not always use the same port. A carrier that works PortMiami and Port Everglades equally avoids a second vendor.
- Visibility. When cargo is being consolidated from multiple sources, knowing what has physically arrived matters more than knowing what was promised.
Practical sequencing
The transshipment moves that run smoothly tend to share a pattern: the export booking and cutoff are known before the import container is even pulled, the consolidation facility has the destination sort plan in advance, and the empty return is scheduled rather than improvised. Everything else is logistics theatre.

Frequently asked questions
Do transshipment containers pay U.S. duty?
Cargo that moves under a Transportation and Exportation in-bond entry and leaves the country without entering U.S. commerce generally does not incur U.S. duty. Cargo that is formally entered and later exported follows different rules. Confirm treatment for your specific shipment with a licensed customs broker.
Can any trucking company move transshipment cargo?
No. Cargo travelling in-bond must be moved by a carrier approved by U.S. Customs and operating under a customs bond. Ask for the bond number before booking, because a non-bonded carrier simply cannot take the load.
How long does import-to-export turnaround take in Miami?
It depends on the export vessel schedule more than on the trucking. The controlling constraint is usually the outbound cutoff, so the practical answer is to work backward from the cutoff and build the import pickup, strip, sort, and re-stuff into that window.
