Why hubs exist at all
Carriers run the largest vessels they can fill, because cost per container falls sharply with vessel size. A modern transpacific ship carries upwards of 14,000 TEU. No Caribbean island generates annual volume approaching a single sailing of that size, and most generate a small fraction of it.
The result is a hub-and-spoke network. Mainline vessels connect major ports across oceans. Feeder vessels, far smaller, distribute from the hub to the islands. Your container rides the mainline for the long expensive leg and the feeder for the short one, and the hub is where it changes hands.
This is not a Caribbean peculiarity. It is how global container shipping works everywhere volume is thin. What is specific to the Caribbean is which ports became the hubs, and the answer has almost nothing to do with the size of their local markets.
The Windward Passage logic
Kingston and Caucedo, and prospectively Mariel in Cuba, sit on the Windward Passage. That location puts them a small deviation off the mainline route between Asia and the United States East Coast.
That geometry is the whole explanation. A carrier running Asia to Savannah can call Kingston without materially lengthening the voyage, discharge Caribbean-bound boxes, and carry on. Calling Bridgetown or Port of Spain instead would mean a substantial detour for a small parcel of cargo. Those ports therefore receive feeders and not mainline vessels, permanently, and no amount of local investment changes the geography.
The commercial consequence is that hub status is durable. When you plan a Caribbean supply chain around Kingston or Caucedo, you are planning around a structural feature, not a carrier's current preference.
The four hubs
| Hub | Location | Operator context | Principally feeds |
|---|---|---|---|
| Manzanillo (MIT), Cristóbal, Balboa | Panama | Canal-adjacent, both coasts | Western and southern Caribbean, Central America, the Colón Free Zone |
| Kingston (KFTL) | Jamaica | CMA CGM Group subsidiary | Eastern and central Caribbean |
| Caucedo | Dominican Republic | DP World | Hispaniola, eastern Caribbean |
| Cartagena | Colombia | On the Asia–LatAm string | Southern Caribbean, north coast South America |
Panama is the natural first touch for transpacific tonnage and the only one of the four that is also a major destination in its own right, because of the Colón Free Zone. Cargo relaying here can be discharged into the zone, held, and moved onward in small lots rather than continuing as a single consignment. That option does not exist at the other three in the same form.
Kingston operates through Kingston Freeport Terminal, a CMA CGM Group subsidiary. This has a direct commercial implication: a CMA CGM booking relayed through Kingston is a single-carrier movement rather than an interline handoff between companies with no shared incentive to protect your connection. On a lane where the connection is the main risk, that is worth more than a marginally better rate.
Caucedo applies the same Windward Passage logic as Kingston, with deep-water capacity and modern handling. It is the natural hub for Hispaniola and competitive for the eastern arc.
Cartagena appears on the documented Asia–Latin America strings and has a strong onward network into the southern Caribbean and the north coast of South America. One published service calls Qingdao, Ningbo and Shanghai, then Busan, then Manzanillo, Cartagena, Charleston, Savannah, Jacksonville and Kingston, which shows how these hubs chain together rather than competing cleanly.
What actually happens at the relay
Three things have to line up: the mainline vessel arrives, the box is discharged and staged, and the feeder departs with it aboard. Each is a queue, and queues compound.
Realistic dwell at the hub is 3 to 10 days. That range is not imprecision, it is the difference between catching the intended feeder and catching the next one.
The critical property of feeder services is frequency. On the busiest hub-to-island pairs, a feeder runs weekly. On thinner routes, less often. A missed connection therefore does not cost a day. It costs a week, sometimes more, because the next connecting vessel is a week out. This single mechanism is the largest source of transit variance on China-to-Caribbean lanes, larger than customs, weather or origin delays combined.
Nothing about that is visible in a quoted transit time. A forwarder quoting "35 days" is quoting the good case.
Why control of the hub leg is the thing to buy
If the mainline carriage and the feeder carriage are separate bookings with separate parties, nobody owns the connection between them. The mainline carrier's obligation ends at discharge. The feeder operator's begins at loading. The gap between those two events is where containers sit for an extra week, and there is no party whose job it is to notice.
The practical protections, in order of effectiveness:
- Book the whole movement as one. Origin to final port under a single forwarder or a single carrier's network, so the connection is internal rather than a handoff.
- Prefer a single-carrier relay where one exists. A CMA CGM box through CMA CGM's own Kingston terminal has fewer seams than an interline move.
- Book before the cutoff, not at it. On LCL especially, a late booking misses the sailing, and behind the sailing sits the connection. One missed cutoff costs roughly two weeks.
- Ask which hub your cargo will relay through before you book. If nobody can tell you, that is the answer to a different and more important question.
Choosing routing by destination
The hub is not usually yours to choose directly, but the routing that implies it often is.
For the western and southern Caribbean, Panama routings are typically shortest, and they carry the additional option of staging in the free zone rather than moving straight through. For the eastern arc, Kingston and Caucedo dominate. For the southern Caribbean and the South American north coast, Cartagena competes strongly.
Where an importer serves several destinations, the hub stops being a routing detail and becomes a strategy: one full container from China into a free zone at the hub, then short feeder movements out as demand appears. That model is covered in Colón Free Zone re-export, and the mode decision behind it in LCL vs FCL for Caribbean imports.
Per-destination relay patterns and realistic leg-by-leg timings are in China to Caribbean transit times, and the full lane structure in shipping from China to the Caribbean. Individual lanes covering hub choice in detail include Jamaica, which is served at the hub itself, the Dominican Republic, likewise, and Barbados, which is always a feeder destination.
Interworld Freight books the mainline and feeder legs as a single movement on these lanes, through LCL consolidation and full container load services, specifically so that the relay connection has an owner.
Frequently Asked Questions
What is a transshipment hub?
A port where cargo is transferred from one vessel to another rather than delivered to its final destination. In the Caribbean the principal hubs are Manzanillo, Cristóbal and Balboa in Panama, Kingston in Jamaica, Caucedo in the Dominican Republic, and Cartagena in Colombia. Almost all cargo arriving from Asia relays through at least one of them.
Why do Kingston and Caucedo handle so much transshipment?
Because they sit on the Windward Passage, a small deviation off the mainline route between Asia and the United States East Coast. A carrier can call them without materially lengthening the voyage. Ports such as Bridgetown or Port of Spain would require a substantial detour for a small volume of cargo, so they receive feeders instead. The advantage is geographic and therefore permanent.
How long does cargo sit at a transshipment hub?
Typically 3 to 10 days. The wide range reflects whether the box catches its intended feeder or waits for the next one. On busy hub-to-island pairs feeders run weekly, so a missed connection costs about a week rather than a day.
What happens if my container misses its feeder connection?
It waits for the next sailing, which on most Caribbean routes is roughly a week later. This is the single largest source of transit variance on China-to-Caribbean lanes. It is also the risk least visible in a quoted transit time, since quotes assume the connection is made.
How do I stop my shipment being left behind at the hub?
Book the entire movement, origin to final port, with one party so the connection is internal rather than a handoff between a mainline carrier and a feeder operator with no shared obligation. Prefer single-carrier relays where they exist, and book ahead of the cutoff rather than at it, because a missed cutoff also means a missed connection behind it.
Which hub is best for my destination?
Panama routings are usually shortest for the western and southern Caribbean and carry the option of staging in the Colón Free Zone. Kingston and Caucedo dominate the eastern arc. Cartagena is strong for the southern Caribbean and the north coast of South America. The hub is rarely something you specify directly, but the routing that determines it usually is.
