The maximum gross mass for a 20 ft (6.10 m) dry cargo container is 24,000 kg (53,000 lb), and for a 40 ft (12.19 m) container (including the 9 ft 6 in or 2.90 m high cube) it is 30,480 kg (67,200 lb). Allowing for the tare mass of the container, the maximum payload mass is therefore reduced to approximately 22,000 kg (49,000 lb) for 20 ft (6.10 m), and 27,000 kg (60,000 lb) for 40 ft (12.19 m) containers.[36]
