Caribbean hub concentration
Analyses and trade data show Latin America and the Caribbean freight system is concentrated in a few terminals, with Colombia’s Caribbean ports handling the majority of its 126.7 million tons moved — emphasising single‑node dependency risk. At the same time, niche forwarders are marketing dedicated U.S.–Caribbean services, which highlights tradeoffs between scale at major hubs and resilience through specialized lanes.

One country can move 126.7 million tons through its ports in nine months and still have a fragility problem if 108 million of those tons run through one coast. Colombia’s transport ministry said its Caribbean ports handled about 85% of the national total from January to September 2025. (mintransporte.gov.co) That means the map looks diversified on paper but behaves like a system with a few giant valves. The same ministry update said the Pacific handled 16.4 million tons over the same period, a fraction of the Caribbean volume. (mintransporte.gov.co) This is not just a Colombia story. The Economic Commission for Latin America and the Caribbean said its 2023–2024 port report tracks concentration and ranking shifts across the region’s port system, where a relatively small number of terminals dominate container flows. (repositorio.cepal.org) The reason big hubs keep winning is simple: shipping lines save money when they pile more cargo into fewer calls. A major transshipment port like Cartagena can gather boxes from many origins, refill a ship fast, and send them onward on bigger routes than a smaller island port could support on its own. (seatrade-maritime.com) The tradeoff shows up when one busy node has weather delays, labor trouble, draft limits, equipment shortages, or customs bottlenecks. When a network is built around a handful of hubs, a disruption at one terminal can spill into trucking, warehousing, feeder vessels, and store shelves across multiple islands and coasts. (unctad.org) (repositorio.cepal.org) That is why smaller freight firms keep advertising direct or dedicated Caribbean lanes even while the system concentrates. Top of the Line Transport says it works as a local partner for the United States Virgin Islands, coordinating customs clearance, drayage, and site delivery rather than relying only on generic hub-and-spoke routing. (topofthelinetransport.com) Those niche services usually cannot match the raw scale of the biggest terminals. What they sell instead is route control for awkward cargo, island-specific paperwork, and fewer handoffs between mainland port, feeder service, customs broker, and final truck. (topofthelinetransport.com) (approvedforwarders.com) Colombia’s own numbers show how sharp the concentration can get. In January to September 2024, its port zones moved 135.1 million tons, and 118.3 million tons of that passed through the Caribbean region, according to official transport statistics cited by the government and local business coverage. (presidencia.gov.co) (larepublica.co) So the freight picture in the Caribbean is pulling in two directions at once. The region keeps rewarding giant hubs because they are efficient, while shippers keep paying for specialized lanes because efficiency at one node is not the same thing as resilience across the whole network.
