What is a 20 ft TEU?
A 20 ft TEU, or Twenty-Foot Equivalent Unit, is a standard unit of measurement used across the shipping and logistics industry. It reflects the storage capacity of a typical 20-foot-long shipping container. TEU simplifies the way businesses, ports, and shippers around the world talk about container capacity, ship size, and port throughput. Understanding what a TEU is, and specifically what a 20 ft TEU means, can help you navigate the world of international trade with ease.
Breaking Down the 20 ft TEU Container
The 20 ft TEU is the building block of global container shipping. Let’s break down what it actually is:
Dimensions
The standard dimensions of a 20 ft TEU (external) are:
- Length: 20 feet (6.096 meters)
- Width: 8 feet (2.438 meters)
- Height: 8.5 feet (2.591 meters)
Internal dimensions are slightly smaller due to wall and door thickness:
- Internal Length: Around 19.4 feet (5.9 meters)
- Internal Width: About 7.7 feet (2.35 meters)
- Internal Height: About 7.9 feet (2.39 meters)
Capacity and Weight
- Volume Capacity: Roughly 33 – 34 cubic meters (about 1,170 – 1,200 cubic feet)
- Payload Capacity (Weight it can carry): Typically around 28,000 kilograms (62,000 lbs), although this can vary depending on the container’s make and shipping line restrictions.
- Tare Weight (Empty Container): About 2,200 kilograms (4,850 lbs)
What Does “TEU” Stand For?
TEU stands for “Twenty-Foot Equivalent Unit”. One TEU is equal to the size of one standard 20-foot container.
- 1 × 20-foot container = 1 TEU
- 1 × 40-foot container = 2 TEU
So, whenever you encounter “TEU,” remember it’s just a way to compare container capacity based on the 20 ft standard.
Why are TEUs so Important in Shipping?
TEUs allow the shipping industry to have a universal language for capacity, logistics planning, and freight costs. Here’s why they matter:
- Simplicity: TEU provides a consistent measurement, making it easier to compare ship size, port efficiency, or freight rates across the globe.
- Efficiency: Helps ports and shipping companies plan space on vessels and in terminals accurately.
- Cost Planning: Shippers and buyers can calculate shipping needs and costs quickly.
- Scale: TEU statistics reveal trade volumes and trends for countries, ports, and carriers.
