Distinguish empty weight, payload and gross mass for a 40-foot container. Plan delivery using the actual unit’s values and the real mass of its contents.
Three different masses
Tare · empty weight
Tare is the mass of the empty container. Equipment, repairs and conversions can change it. Read the actual unit’s tare and confirm what it includes.
Maximum payload
Payload refers to the contents. Its limit is maximum gross mass minus tare; this alone does not validate concentrated floor loads or lifting conditions.
Maximum gross mass
Gross mass includes the container and its contents. The limit marked on the unit does not replace vehicle, axle, route or handling-equipment limits.
Documented example · 40-foot standard
| Tare · empty weight | 3,750 kg |
|---|---|
| Maximum payload | 28,750 kg |
| Maximum gross mass | 32,500 kg |
Example from the Hapag-Lloyd fleet, checked on 16 October 2026. Values vary by manufacturer and do not describe Container Origin stock. Check the selected unit’s markings and documentation.
Calculate the mass to move
Calculation example: 3,750 kg tare + 10,000 kg contents = 13,750 kg to move. This example does not authorise loading or lifting your unit.
Information to provide
Provide the container identifier, confirmed tare, documented limits, contents mass and load distribution. Specify whether transport will be empty or loaded. Use the specific technical sheet for office, refrigerated, High Cube or converted units.
Confirm transport and handling
The carrier and lifting provider confirm the vehicle, capacity, method and access for the actual mass. Have load distribution and supports checked for your use. Volume in m³ does not establish allowable mass.
