Marine cargo can be divided into two major categories Packed/General Cargo and Unpacked/Bulk Cargo. Unpacked or packed is related to the goods itself and of course it affects what ship type that should be used for transportation.
Further can general cargo be split into there areas of goods: Break bulk, Neo Bulk and Unitizised Cargo.
Break Bulk – is typically when goods is packed in boxes, bags, barrels, crates, drums & on pallets. Ships used for this cargo is Bulk Carriers or combination ships.
Neo Bulk – is typically lumber, paper, steel, cars & trucks. Ships used here are bulk carriers but also specialized RoRo (veihicle carriers) ships for cars & trucks.
Unitized Cargo – is typically cargo that is packed in containers. In this case it is the container carriers that does the job.
Like the packed cargo the bulk carge is also śplit into two areas: Liquid/Wet Bulk and Dry Bulk.
