Is it possible to ship more than one car in a single container?
The answer is YES.
Shipping multiple cars in one 40-foot container is not only possible, but also cost-effective when done correctly.
By using proper loading methods such as decking, multiple vehicles can be safely consolidated into a single container, helping importers and exporters reduce overall shipping costs.
In this blog, we’ll explain how four cars can be shipped in one 40-foot container, what decking is, when it works, and what limitations to consider before choosing this option.
What Is a 40-Foot Container?
A 40-foot container is a standard shipping container widely used in international freight, including vehicle transportation.
It is designed to carry large volumes of cargo securely across long distances and is commonly chosen for car shipments due to its size and availability.
The internal dimensions of a standard 40-foot container are approximately:
- Length: 12.0 meters
- Width: 2.35 meters
- Height: 2.39 meters
Although a 40-foot container can handle heavy loads, space is the main limitation when shipping vehicles. The length, width, and height of the container determine how many cars can be safely loaded inside.
For this reason, the number of vehicles that fit inside a 40-foot container depends largely on vehicle size and loading method, which we’ll explain in the next section.
How Many Cars Fit in a 40-Foot Container?
A standard 40-foot container can carry more than one car, but the exact number depends on the size of the vehicles and how they are loaded.
Without Decking (Floor Load Only)
- Typically, a 40-foot container can fit 2 to 3 cars.
- Cars are loaded end-to-end on the container floor.
- This method works well for sedans and compact vehicles.
- Taller or longer cars may reduce the total number you can fit.
With Decking or Racking
- Using a decking system, it’s possible to fit up to 4 small cars.
- Decking creates a second level inside the container, allowing two cars on the floor and two cars on the upper platform.
- This method maximizes space while keeping vehicles safe.
Key point: The total number of cars depends on vehicle dimensions, container height, and the use of decking or racking systems. For example, SUVs or vans usually take up too much space for four cars in one container.
What Is Decking in Container Car Shipping?
Decking is a loading method used to maximize space inside a shipping container by creating an additional level.
In simple terms, decking involves installing a temporary platform or frame inside a 40-foot container so that cars can be loaded on two levels instead of one.
With decking:
- One or two cars are placed on the container floor
- One or two cars are placed on top of the deck
- All vehicles are carefully secured and lashed to prevent movement during transit
This method allows shippers to safely transport up to four small cars in a single 40-foot container, making it a popular choice for consolidated vehicle shipments.
Decking must be done by experienced professionals, as proper weight distribution and securing are critical for safety. When done correctly, it is a reliable and cost-effective way to ship multiple cars together.
How 4 Cars Are Loaded Using Decking
Shipping four cars in a single 40-foot container requires careful planning and professional handling.
The process typically follows these steps:
- Installation of the decking structure
- A strong metal decking frame is installed inside the container to create an upper level.
- Loading the lower-level cars
- One or two cars are positioned on the container floor and securely lashed to prevent movement.
- Loading the upper-level cars
- The remaining cars are lifted or driven onto the decking platform using ramps or lifting equipment.
- Securing all vehicles
- Each car is tightly secured with straps and wheel chocks to ensure stability during transit.
Once loading is complete, the container is sealed and ready for shipment. When done correctly, this method ensures that all four vehicles remain safe, stable, and well-protected throughout the journey.
Vehicle Size Requirements
Not all vehicles are suitable for decking inside a 40-foot container. The size and height of the cars play a major role in determining whether four vehicles can be shipped together.
Decking works best for:
- Small cars
- Compact sedans
- Hatchbacks
These vehicles typically have lower heights and shorter lengths, making them easier to stack safely inside the container.
Vehicles that are usually not suitable for decking include:
- SUVs
- Vans
- Pickup trucks
- Oversized or modified vehicles
Taller vehicles may exceed the container’s internal height when placed on the upper deck, making four-car loading unsafe or impossible.
Before choosing this option, it’s important to review the exact dimensions of each vehicle to ensure they meet the container and decking requirements.
Is Decking Safe?
Yes, decking is safe when done correctly.
Decking is a commonly used method in container car shipping and has been successfully used for many years. The key to safety lies in professional execution.
When decking is done properly:
- Vehicles are loaded by trained personnel
- Weight is evenly distributed inside the container
- Cars are secured using heavy-duty straps and wheel chocks
- Movement during transit is minimized
However, improper decking can increase the risk of damage. This is why it’s important to work with experienced loaders and reputable shipping companies that follow approved loading practices.
When handled professionally, decking provides a secure and reliable way to ship multiple cars in a single container.
When Decking Is Not Recommended
While decking is a useful solution, it is not suitable for every shipment.
Decking is generally not recommended in the following situations:
- When shipping SUVs, vans, or pickup trucks
- When vehicle height exceeds container limits
- When shipping high-value or luxury vehicles that require extra clearance
- When the shipping line or destination port does not allow decking
- When professional decking services are not available
In these cases, forcing additional vehicles into a container can increase the risk of damage and delay.
For some shipments, alternative options such as standard container loading or RORO shipping may be safer and more practical.
Conclusion
Shipping four cars in one 40-foot container can be a practical and cost-effective solution when the right conditions are met.
For small and compact vehicles, decking helps maximize container space and reduce the overall shipping cost per car.
The success of this method depends on proper vehicle sizing and professional loading. When handled correctly, it provides an efficient and reliable way to ship multiple cars in a single container.
Frequently Asked Questions
1) Decking vs RORO: Which Is Better for Shipping Cars?
Both options are effective, but the best choice depends on your needs. Decking allows multiple cars to be shipped in one container, offering better protection and lower cost per vehicle.
RORO is often cheaper for single vehicles but provides less protection and limited route availability.
2) How Many Cars Can Fit in a 20-Foot Container?
A 20-foot container typically fits one car, or two very small cars in rare cases. Due to limited space and height, decking is usually not practical in a 20-foot container.
3) Is Container Car Shipping Better Than RORO?
Container shipping offers greater security and protection, especially for high-value vehicles or consolidated shipments. RORO can be a cost-effective option for drivable vehicles but comes with more exposure during handling and transit.
4) What Are Common Mistakes When Shipping Multiple Cars in a Container?
Common mistakes include misjudging vehicle size, using inexperienced loaders, improper securing, and attempting to overload the container. These issues can lead to damage, delays, or rejected shipments.
5) Is Decking Allowed on All Shipping Lines and Routes?
No. Decking policies vary by shipping line, port, and destination country. Some carriers require certified decking systems, while others may restrict or prohibit decking altogether.
6) Are SUVs Suitable for Decking in a Container?
In most cases, no. SUVs, vans, and pickup trucks are usually too tall for upper-level loading and exceed container height limits when decking is used.
7) Do Cars Need to Be Drained of Fuel When Shipping in a Container?
Most shipping lines require fuel levels to be kept very low, usually less than one-quarter of a tank. Specific requirements depend on the carrier and destination regulations.
8) Is Decking Safe for Long-Distance Shipping?
Yes, when performed by experienced professionals using proper securing methods. Safety depends on correct weight distribution, certified equipment, and compliance with shipping line requirements.
9) Which Option Is More Cost-Effective for Multiple Cars?
For small and compact vehicles, decking in a 40-foot container is often more cost-effective than shipping cars individually. However, the final cost depends on vehicle size, route, and handling requirements.
