On 1 July 2016, new requirements to verify the gross mass of a packed container enter into force under the International Convention for the Safety of Life at Sea (SOLAS). Shippers must verify the gross mass of packed containers through two methods. The First Method consists of weighing the packed container using calibrated and certified equipment. Under the second method, all packages and cargo items are weighed, including the mass of pallets, dunnage and other securing material to be packed in the container and the sum of these masses is then added the tare mass of the container, using a certified method approved by the competent authority of the State in which packing of the container was completed. In France, the order of 28 April 2016 allows a 5% tolerance between the declared mass and the actual mass of the container. In case this limit is exceeded, the carrier may refuse to load the container on board.
