Shipping container weight
How heavy is an empty and fully loaded shipping container?
The weight of a shipping container is essential for safe transport, lifting operations and cost control. Knowing the tare weight (empty), maximum payload and total gross weight helps prevent overloading and ensures safe use of cranes, trucks and vessels.

What is the difference between tare, payload and gross weight?
Shipping container weight is divided into three key specifications:
- Tare weight: the weight of the empty container
- Maximum payload (net weight): the maximum weight of cargo that can be loaded
- Maximum gross weight: the total weight of the container including cargo
These values are critical for safe handling and are defined under international CSC regulations. For most standard containers, the maximum gross weight is 30,480 kg.
How much does a standard shipping container weigh?
Below is an overview of the most common shipping container weights for 20ft, 40ft and 40ft high cube containers.
| 20ft | 40ft | 40ft High Cube | |
|---|---|---|---|
| Maximum payload | 28,300 kg (62,390 lbs) | 26,860 kg (59,220 lbs) | 26,660 kg (58,770 lbs) |
| Maximum gross weight | 30,480 kg (67,200 lbs) | 30,480 kg (67,200 lbs) | 30,480 kg (67,200 lbs) |
| Tare weight | 2,180 kg (4,800 lbs) | 3,620 kg (7,980 lbs) | 3,820 kg (8,420 lbs) |
- Typical cargo: pallets, consumer goods, machinery parts
- Example: a 20ft container can hold approx. 10–11 standard pallets depending on weight
How heavy is a reefer container?
Reefer containers are heavier than standard containers due to the built-in cooling unit. This reduces the available payload capacity.
| 10ft | 20ft | 40ft | |
|---|---|---|---|
| Maximum payload | 27,440 kg | 27,541 kg | 30,420 kg |
| Maximum gross weight | 30,480 kg | 30,480 kg | 35,000 kg |
| Tare weight | 3,040 kg | 2,940 kg | 4,580 kg |
- Typical cargo: food, pharmaceuticals, temperature-sensitive goods
- Note: high cube reefers may have slightly different weights
Because of the cooling system, reefers require additional power (gensets) and careful weight planning, especially in warm climates such as Southern Europe and the Middle East.
What does a flat rack container weigh?
Flat rack containers are designed for heavy and oversized cargo such as machinery and vehicles. They are available as fixed-end and collapsible versions.
| 40ft Fixed-end | 40ft Collapsible | |
|---|---|---|
| Maximum payload | 26,280 kg | 39,140 kg |
| Maximum gross weight | 30,480 kg | 45,000 kg |
| Tare weight | 4,200 kg | 5,860 kg |
- Typical cargo: heavy machinery, pipes, vehicles, project cargo
- Advantage: high payload capacity and flexibility for oversized loads
Why is container weight important?
Incorrect weight calculations can lead to unsafe situations, transport delays and additional costs. Overloading a container can result in fines, rejected shipments or damage to equipment.

FAQ about shipping container weight
Why is tare weight important?
Tare weight determines how much cargo you can safely load without exceeding the maximum gross weight.
How do I calculate total container weight?
Add the tare weight of the container to the weight of your cargo to get the total gross weight.
What happens if I overload a container?
Overloading can lead to safety risks, fines, rejected shipments and damage to transport equipment.
Do I need different lifting equipment for reefers?
Yes, reefers are heavier due to cooling units and may require adjusted lifting capacity.
Are there legal limits for container weight?
Yes, standard containers typically have a maximum gross weight of 30,480 kg under international regulations.
