A cargo vessel designed to transport standardized shipping containers. While RoRo is the default for vehicle logistics, container shipping plays a specific role when enclosed protection, port flexibility, or mixed cargo is required.
What is a Container Ship?
Container ships carry standardized 20-foot and 40-foot boxes stacked in cell guides, loaded and unloaded by gantry cranes at container terminals. They handle roughly 90% of global non-bulk trade, but for vehicle logistics, they're the exception rather than the rule.
Most OEMs and fleet operators default to RoRo for production vehicles. Container shipping enters the picture in specific situations where RoRo either isn't available or isn't the right fit.
When Vehicles Go in Containers
Not every vehicle moves on a RoRo vessel. Container shipping makes sense for:
- Motorcycles, ATVs, and powersports: too small for efficient RoRo stowage, easily secured inside a 20ft or 40ft container
- Inoperable or damaged vehicles: can't be driven on/off a RoRo vessel under their own power, and towing adds cost and complexity
- Personal vehicle relocations: individuals shipping a single car often find containerized options more accessible since container services call at far more ports worldwide
- High-value exotics and classics: fully enclosed containers eliminate salt spray exposure and weather risk during transit, which matters for a $300,000 vehicle
- Mixed cargo: when vehicle parts, accessories, or personal effects need to ship alongside the vehicle itself
How many vehicles fit?
A standard 40ft high-cube container holds 2-4 vehicles depending on size, loaded using racking systems that stack cars vertically. A 20ft container fits 1-2 small sedans. Loading takes 2-4 hours per container versus minutes per vehicle on RoRo, which is why container shipping only wins on specific use cases, not volume.
Container vs RoRo for Vehicle Moves
The two modes serve fundamentally different needs. Here's what matters for vehicle logistics decision-makers:
Cost. RoRo is 30-50% cheaper per vehicle on most trade lanes. Container rates are calculated per box, not per unit, so you're paying for unused space unless the container is fully loaded. On the Japan-to-Middle East lane, shipping a sedan by RoRo runs $400-600 versus $800-1,200 containerized.
Damage risk. Containerized vehicles are sealed and protected from weather, but loading and unloading with forklifts and racking systems introduces handling damage that doesn't exist in drive-on/drive-off operations. In practice, damage rates are comparable: RoRo has salt spray exposure, containers have loading/unloading risk.
Port availability. Container services call at virtually every commercial port worldwide. RoRo is limited to specialized terminals, roughly 200 globally compared to thousands of container ports. For destinations without a RoRo service, containers may be the only option.
Speed. RoRo loading processes 100+ vehicles per hour. Container stuffing handles 4-8 vehicles per hour at best. For volume shipments, the math is clear.
Container Sizes at a Glance
The standard units in vehicle logistics:
- 20ft (1 TEU): 33 cubic meters. Fits 1-2 small vehicles or motorcycles. Common for personal relocations.
- 40ft Standard (2 TEU): 67 cubic meters. The workhorse for 2-3 vehicle shipments with racking.
- 40ft High Cube (2 TEU): 76 cubic meters. The extra foot of height accommodates SUVs and trucks that won't fit in standard containers.
Operator tip
If you're shipping more than 4 vehicles to a port with RoRo service, containerized shipping almost never makes financial sense. The break-even point where containers compete with RoRo is typically 1-3 units on routes where RoRo frequency is low or unavailable.
FAQ
When should I use a container instead of RoRo for vehicles?
Use containers when shipping to a port without RoRo service, when the vehicle is inoperable, when you need full weather protection for high-value units, or when you're combining vehicles with other cargo in the same box. For standard production vehicles in volume, RoRo is almost always more cost-effective.
How many cars fit in a 40ft container?
Typically 2-4 vehicles using specialized racking systems, depending on vehicle size. Sedans and compacts allow for 3-4 units. SUVs and trucks usually limit you to 2.
Is container shipping safer than RoRo for luxury vehicles?
The enclosed container eliminates salt spray and weather exposure, which matters for delicate paintwork. However, the loading process (racking, forklift positioning) introduces its own damage risks. Many luxury vehicle shippers use enclosed containers with custom padding, which adds $500-1,000 per unit but provides the highest protection level available.
