The tare weight of a container is included in the total weight of the containerized goods transported, also called the gross-gross weight of goods. The gross weight of containerized goods transported can be calculated by deducting the tare weight of the container from the gross-gross weight. If information about the tare weight is missing, then it may be estimated using the averages below:
- 20-foot long ISO container: 2.3 tonnes;
- 40-foot long ISO container: 3.7 tonnes;
- Over 20-feet and under 40-feet long ISO container: 3.0 tonnes;
- Over 40-feet long ISO container: 4.7 tonnes.
