In order to ensure that boxes can be handled safely, the position of the center of gravity must be indicated by an appropriate symbol on boxes as of 1,000 kg gross weight.

The center of gravity has been unambiguously indicated if the symbol is present on at least two adjoining walls of the box. To guarantee safety during handling and transportation, it makes sense to mark the center of gravity on all four side walls. The center of gravity is to be indicated in accordance with DIN EN ISO 780 or in accordance with the regulations of the destination country, see chapter 11.
