A trade lane (or trade route) refers to a specific pathway along which goods are transported between two or more locations, typically across international borders. Trade lanes are established based on the flow of goods and the economic relationships between countries or regions. They encompass both maritime and air routes and play a crucial role in global supply chains by facilitating the movement of goods and fostering international trade.
Transit time refers to the duration it takes for goods or shipments to travel from their origin to their destination. It is a crucial metric in supply chain and logistics management, as it directly impacts delivery schedules, inventory levels, and customer satisfaction. Transit time encompasses the entire journey of a shipment, including transportation, handling, and processing at various checkpoints along the route.
Transloading refers to the process of transferring goods or cargo from one mode of transportation to another, typically from one type of truck or railcar to another, or from rail to truck and vice versa. This logistical practice is often employed to optimize transportation routes, reduce costs, and improve overall efficiency in supply chain operations.
A Transportation Management System (TMS) is a specialized software solution designed to streamline and optimize transportation and logistics operations within supply chains. It provides functionalities to effectively manage and control the movement of goods from origin to destination.
Transportation lead time refers to the duration it takes for goods to be transported from the point of origin to the final destination. It encompasses the time required for transportation activities, including loading, transit, and unloading, across various modes of transport such as road, rail, air, or sea.
A transshipment is the process of transferring goods from one transportation vehicle or vessel to another during their journey from origin to destination. It typically occurs at intermediary points along the supply chain route, where cargo is transferred between different modes of transportation, carriers or vessels.
Twenty-foot Equivalent Unit (TEU) is a standard unit of measurement used in the shipping industry to quantify the cargo-carrying capacity of container vessels. It represents the volume of a standard twenty-foot-long shipping container.
An Ultra Large Container Vessel (ULCV) is a massive container ship used on major trade routes, capable of carrying over 14,000 TEUs.
Vendor Managed Inventory (VMI) is a supply chain management strategy where the supplier or vendor takes responsibility for managing the inventory levels of their products at the customer's or retailer's location. In this arrangement, the vendor monitors the inventory levels based on agreed-upon criteria such as sales data or inventory levels, and initiates replenishment as needed.
Verified Gross Mass (VGM) is a term used in the shipping industry to refer to the total weight of a packed container, including its contents and packaging materials. It is a crucial requirement mandated by the International Maritime Organization (IMO) under the Safety of Life at Sea (SOLAS) convention to enhance safety in maritime transportation.
A floating structure with its own mode of propulsion designed for the transport of cargo and/or passengers. In the Industry Blueprint 1.0 "Vessel" is used synonymously with "Container vessel", hence a vessel with the primary function of transporting containers.
A vessel sharing agreement (VSA) is a cooperative arrangement between shipping companies that allows them to share space and resources on vessels for specific routes.
Vessel bunching refers to the situation where multiple vessels arrive at a port simultaneously or within a short period, leading to congestion and delays. This clustering of vessels can overwhelm port facilities, causing extended wait times for berthing, loading, and unloading operations.
A vessel call sign is a unique identifier assigned to a ship for radio communication purposes. It is used to distinguish the vessel from others in maritime communication systems, including VHF radios and satellite communications.
A vessel omission (sometimes called a port omission) occurs when a scheduled vessel does not call at a planned port during its voyage. This disruption means that the vessel skips the port entirely, which can impact the transportation and delivery schedules of goods.
In cargo shipping, vessel rotation is the planned sequence of port calls that a shipping vessel follows on its route to optimize cargo loading and unloading operations.
The timetable of departure and arrival times for each port call on the rotation of the vessel in question.
A journey by sea from one port or country to another one or, in case of a round trip, to the same port.
Warehouse utilization is a logistics metric that refers to the effective use of available warehouse space for storing goods and inventory.
Order for specific transportation work carried out by a third party provider on behalf of the issuing party.
Logistics yard management refers to the process of overseeing and controlling the movement of trucks, trailers, containers, and other vehicles within a yard or distribution center. This includes tasks such as scheduling, tracking, and coordinating the arrival, departure, and storage of these vehicles.

Global Port Performance: November
Vietnam's Origin Ports Hit a Breaking Point in 2025 And Most Food Importers Missed It
Your shipment tracking may say "in transit." But if you're importing Vietnamese coffee or seafood, there's a good chance your container isn't moving. It could be sitting in an origin port terminal for over a week before the vessel even leaves.
Vietnam's two main export ports serving the US food trade saw container dwell times more than double this year.
What Happened in Vietnam
At Vung Tau, containers averaged 67.9 hours (2.8 days) in January 2025. By November, that figure had jumped to 229.7 hours (9.6 days) a 238% increase. Ho Chi Minh City followed the same pattern: 116.4 hours in January, 190.3 hours in November.
Both ports operated normally through February. Then something happened between March and June. Dwell times spiked to 8-10 days and never recovered. They stayed elevated through the rest of the year.
Several developments coincided with that March-June window. In May, Saigon Newport Corporation announced a congestion mitigation plan for Cat Lai Port, which handles nearly 50% of Vietnam's container throughput. The Vietnam Association of Seafood Exporters reported that 30% of Mekong Delta export orders were delayed in May 2025 due to container shortages. By June, carriers had imposed peak season surcharges. Regional pressure built throughout the period, with Southeast Asian ports accounting for 23% of global vessel capacity waiting for berths by mid-2025.
We can't definitively say what caused the spike port capacity limits, equipment shortages, carrier scheduling changes, or some combination. But the fact that dwell times stayed elevated for six months suggests structural problems, not temporary disruptions.
This matters because Vietnam exported $4.7 billion in coffee during the first five months of 2025, up 73.9% year-over-year in Q1. For US food importers, Vietnam is a critical source for coffee, seafood, and produce all products where time matters.

How Vietnam Compares to Other Food Export Ports
Vietnam's story stands out because of the sudden deterioration. Other major food export ports either stayed consistently problematic or actually improved throughout the year.
Ecuador and Colombia: Consistently high, not getting worse
Guayaquil, Ecuador fluctuated between 152-232 hours throughout the year, averaging around 8 days. Cartagena, Colombia showed similar volatility, ranging from 150-234 hours with no clear trend up or down.
Ecuador shipped 719,153 metric tons of shrimp in the first half of 2025, up 17% year-over-year. For importers working these origins, the 2025 data doesn't reveal new problems it confirms that these ports have been operating with week-plus dwell times consistently.
The difference from Vietnam is predictability. You can plan around consistent 7-9 day dwell. You can't plan around a port that suddenly triples its dwell time mid-year.
Peru and Panama: Steady monthly improvements
The monthly data reveals that these weren't sudden improvements they were consistent, progressive reductions.
Callao, Peru started at 138 hours in January and dropped steadily month-by-month to 59.3 hours by November. Every single month showed improvement.
Balboa, Panama's trend is even more dramatic: 177 hours in January, then a sharp drop in February to 83 hours, continuing down to just 31 hours by November. The improvements were consistent and sustained.
Both improvements coincided with major infrastructure investments. DP World's Bicentennial Pier expansion at Callao, inaugurated in June 2024, drove an 80% increase in operational capacity to nearly 3 million TEUs annually. Panama's improvements aligned with the canal's recovery from drought restrictions and Balboa's record container volumes, up 13.7% in 2024.
Whether infrastructure directly caused the improvements or other operational factors played a role is unclear. But the month-by-month trajectory shows sustained operational gains, not one-time flukes.
Brazil: Gradual, consistent improvement
Santos shows a different pattern from Panama and Peru not a dramatic drop, but steady month-over-month improvements. The port went from 161 hours in January to 89 hours in November, declining consistently almost every single month.
Yet industry reports described 84% of vessels at Santos facing delays averaging 12 days throughout 2024-2025. This suggests different bottlenecks container processing within terminals sped up even as overall port congestion persisted.

How do food importers cope?
The USDA projects horticultural products will represent 49% of US agricultural import value in fiscal year 2025. Food importers can't abandon Vietnam, Ecuador, or Colombia these origins provide products US consumers want at prices that work. But the 2025 data suggests practical adjustments:
For Vietnam sourcing:
Build 7-10 extra days into lead times and delivery commitments. What used to be 21 days ocean transit is now 28-31 days including origin dwell. Negotiate extended free time at origin in carrier contracts, or structure contracts so detention only starts after vessel departure rather than terminal gate-in.
Evaluate alternatives:
Peru's 2-3 day dwell versus Ecuador's 7-9 days translates to a full week of reduced detention costs and earlier market arrival. The monthly trends show Peru's improvements weren't a fluke they were sustained across 10 months. If your products can source from Peru instead of Ecuador or Colombia, the dwell time difference is material.
Diversify when possible:
If sourcing Vietnamese coffee, consider spreading containers across multiple origin ports rather than concentrating everything through Ho Chi Minh City or Vung Tau.
The ports that improved in 2025 Peru, Panama, Brazil show that change is possible. The monthly trends prove these weren't statistical anomalies but sustained operational improvements. Whether Vietnam's ports follow that path in 2026 remains to be seen. But the 2025 baseline is clear: origin port dwell deserves the same attention destination ports get. It's earlier in the supply chain, harder to see, and just as expensive when it goes wrong.
