On 1st July 2016 the International Maritime Organization (I.M.O) introduced 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). There has always been a requirement in SOLAS to declare the gross mass of cargo and containers but the new requirement adds an extra level requiring verification of the mass. This is to ensure that the mass declared is a true reflection of the gross mass of the packed container, in order to avoid injury, cargo damage, loss of containers, and so on.
The SOLAS regulation allows for two methods to verify the gross mass of packed containers:
Take a loaded container over a weighbridge, subtract the weight of the truck, chassis, and fuel to get the weight of the packed container.
Weight all packages and cargo items, including the mass of pallets, dunnage and other packing and securing material to be packed in the container, and add the tare mass of the container to the sum of the single masses of the container’s contents.
