Dry cargoes, particularly those carried in bulk and bagged, are subject to disputes arising related to the volume of cargo having been declared at the load port and that having been delivered at the disport. These disputes can arise due to a number of contributing factors, some of which are more controllable than others to prevent. Such disputes are also more likely more frequent in certain jurisdictions despite efforts by shipowners and their crews that are made to prevent them.
