How Much Does a Shipping Container Weigh? Tare, Gross and Payload Explained

If you are buying a shipping container, weight is one of the first practical figures you will need. It affects how the unit is delivered, whether your ground can support it, and how much you can safely load inside. The trouble is that a single container has three different weights, and they are easy to confuse.

This guide explains the three figures that matter, sets out typical weights across the main container sizes, and shows you where to find the exact weight for the unit you are buying.

Tare, Gross and Payload: The Three Weights That Matter

Every shipping container is described using three separate weights. Understanding the difference is the key to everything else on this page.

Tare weight: the weight of the empty container on its own, with nothing inside. This is the figure you need for delivery and lifting.

• Maximum gross weight: the heaviest the container is ever allowed to be, including its own tare weight plus everything loaded into it. This is a safety limit set by the manufacturer and certified for shipping.
• Payload (net weight): the maximum weight you can actually load inside. It is simply the maximum gross weight minus the tare weight.
• In plain terms: tare is the box empty, gross is the box at its absolute limit, and payload is what you are allowed to put in it.

How Much Does a Shipping Container Weigh by Size?

The figures below are typical industry averages for standard steel containers. Exact weights vary by manufacturer, age and specification, so always treat these as a guide rather than a guarantee.

• 10ft: tare approx. 1,300 kg (1.3 t), maximum gross approx. 10,160 kg, maximum payload approx. 8,860 kg.
• 20ft standard: tare approx. 2,200 kg (2.2 t), maximum gross 30,480 kg (30.5 t), maximum payload approx. 28,280 kg.
• 40ft standard: tare approx. 3,750 kg (3.7 t), maximum gross 30,480 kg (30.5 t), maximum payload approx. 26,730 kg.
• 40ft hi-cube: tare approx. 3,940 kg (3.9 t), maximum gross 30,480 kg (30.5 t), maximum payload approx. 26,540 kg.

A 20ft container weighs around 2.2 tonnes empty, while a 40ft container weighs closer to 3.7 tonnes despite being only twice the length. The extra steel in the longer floor and side walls accounts for the difference. A hi-cube is taller than a standard unit, so it carries slightly more tare weight again.

Some older 20ft units are certified to a lower maximum gross weight of around 24,000 kg rather than 30,480 kg. If maximum loading matters to your use, this is worth confirming before you buy.

Why Container Weight Matters

These figures are not just technical details. They have a direct bearing on three practical parts of owning a container.

• Crane and HIAB delivery: containers are delivered by HIAB lorry, a vehicle with a crane mounted on the back that lifts the unit onto your site. The crane is rated to lift the empty tare weight, so an empty 20ft or 40ft unit is well within range. A pre-loaded or part-converted container is heavier and may need to be assessed in advance.
• Ground-bearing capacity: a container concentrates its weight onto small contact points at each corner. A loaded 20ft unit sitting near its gross limit can exceed 30 tonnes. Soft ground, tarmac in warm weather, or unsupported slabs may not cope, which is why a level, firm and load-bearing base matters.
• Onward transport and craneage: if you ever need to move a loaded container, both the haulage vehicle and any crane must be rated for the combined weight. Knowing your payload keeps you the right side of legal axle limits and lifting safety.

Where to Find the Exact Weight of Your Container

Every certified shipping container carries a CSC plate (a small metal data plate, usually on the left-hand door). It lists the unit’s exact tare weight and maximum gross weight in both kilograms and pounds. This is the authoritative figure for your specific container, so it is always worth checking against the guide figures above.

At Container Sales (UK) Ltd we supply new and used containers across Scotland and the North East of England, and our team can confirm the exact weight and loading limits of any unit before you commit. Browse our general purpose containers or get in touch to talk through your requirements.

Frequently Asked Questions

How much does a 20ft shipping container weigh?

A standard 20ft shipping container weighs around 2,200 kg (2.2 tonnes) empty. Its maximum gross weight is typically 30,480 kg, giving a usable payload of roughly 28,280 kg.

How much does a 40ft shipping container weigh?

A standard 40ft container weighs around 3,750 kg (3.7 tonnes) empty, and a 40ft hi-cube around 3,940 kg. Both share the same 30,480 kg maximum gross weight, so payload is roughly 26,500 to 26,700 kg.

What is the difference between tare weight and gross weight?

Tare weight is the empty container on its own. Gross weight is the maximum total the container is allowed to reach, including everything loaded inside. The difference between the two is your payload.

Can my delivery vehicle lift a full container?

HIAB delivery lifts an empty container, which sits well within the crane’s rating. Lifting a loaded container is a separate job that needs equipment rated for the combined weight, so always tell your supplier if a unit is pre-loaded.

Where can I find the exact weight of my container?

Check the CSC plate fitted to the door of the container. It lists the certified tare and maximum gross weight for that specific unit. Our team can also confirm these figures for any container we supply.
