TEU (Twenty-foot Equivalent Unit)
Last updated: June 14, 2026
- TEU is the standard unit for measuring container ship capacity and port throughput — one 20ft container = 1 TEU
- A 40ft container = 2 TEU; the largest container ships carry over 24,000 TEU
- Qingdao port handles approximately 25-27 million TEU annually, ranking among global top 10
TEU (Twenty-foot Equivalent Unit) is the standard unit for measuring container ship capacity and port throughput. One 20ft container equals 1 TEU; one 40ft container equals 2 TEU. TEU is used universally by carriers, ports, and industry analysts to compare vessel sizes, port volumes, and trade flows.
Chinese: 标准箱 / 20英尺当量单位 (Biāozhǔn xiāng)
Why TEU Matters
TEU is the universal yardstick of container shipping. When a carrier announces a new vessel of 24,000 TEU capacity, or a port reports handling 25 million TEU annually, everyone in the industry understands the scale. For shippers, TEU is less relevant day-to-day — you typically book by FCL container count or LCL cubic meters — but understanding TEU helps interpret carrier capacity announcements and freight rate trends.
Practical Example
A Great Hensen client ships 10 x 40ft containers of machinery from Qingdao to Santos, Brazil. The shipment volume in TEU is 10 x 2 = 20 TEU. On a vessel booking confirmation, the carrier reports allocation as 20 TEU. When the same client later ships 5 x 20ft containers for a smaller order, that is 5 TEU. The client's total monthly volume with this carrier is 25 TEU — a figure used to negotiate volume-based freight rate discounts.

Frequently Asked Questions
How is TEU different from FEU?
TEU (Twenty-foot Equivalent Unit) is based on a 20ft container. FEU (Forty-foot Equivalent Unit) is based on a 40ft container. 1 FEU = 2 TEU. In practice, most carriers report capacity in TEU, while some trade statistics use FEU. When comparing port throughput or vessel capacity, always check which unit is being used.
How many TEUs do the largest container ships carry?
As of 2026, the largest container ships in service — MSC's Irina-class and similar ultra-large container vessels (ULCVs) — have capacities exceeding 24,000 TEU. These vessels are primarily deployed on Asia-Europe routes and can only call at a limited number of deep-water ports. The typical vessel calling at Qingdao ranges from 5,000 to 20,000 TEU depending on the trade lane.
What is Qingdao port's annual TEU throughput?
Qingdao port handles approximately 25-27 million TEU annually (2024-2025 data), making it the fourth-largest container port in China and consistently ranked in the global top 10. Qingdao is also China's leading port for refrigerated containers and a major hub for DG cargo handling in northern China. Ship with us from Qingdao headquarters.
