s. Much international transshipment also takes place in designated customs areas, thus avoiding the need for customs checks or duties, otherwise a major hindrance for efficient transport. An item handled (from the shipper's point of view) as a single movement is not generally considered transshipped, even if it changes from one mode of transport to another at several points. Previously, it was often not distinguished from transloading, since each leg of such a trip was typically handled by a different shipper. Transshipment is normally fully legal and an everyday part of world trade. However, it can also be a method used to disguise intent, as is the case with illegal logging, smuggling, or grey-market goods.


Transshipment at container ports or terminals

The transshipment of containers at a container port or terminal can be defined as the number (or proportion) of containers, possibly expressed in TEU, of the total container flow that is handled at the port or terminal and, after temporary storage in the stack, transferred to another ship to reach their destinations. The exact definition of transshipment may differ between ports, mostly depending on the inclusion of inland water transport (barges operating on canals and rivers to the

In both cases, a single, unique, transshipped container is counted twice in the port performance, since it is handled twice by the waterside container cranes (separate unloading from arriving ship A, waiting in the stack, and loading onto departing ship B).


Transshipment at sea

Transshipment at sea is done by transferring goods from one ship to another.


Fisheries

In global fisheries transshipment is used to transfer catch to refrigerated cargo vessels that also supply fishing vessels with fuel, food, equipment and personnel allowing them to stay at sea for months or even years. This guarantees that fish quickly find their way to the market without a decrease in quality. Since transshipment at sea encounters often happen on the high seas, in regions with poor regulation and oversight, they are also used to disguise criminal activities such as illegal, unreported and unregulated fishing, Unfree labour, forced labor, human trafficking and Illegal drug trade, drug smuggling. Several states and Regional fisheries management organisation, regional fishery management organizations have therefore prohibited the practice for certain vessel types or issued a complete ban within their zone of jurisdiction.


Bulk products

Transshipment at sea also occurs in the export of bulk products. Choosing to transship reduces capital costs for port developers and can overcome problems arising from limited access to deep water. Loading barges typically specify 4 to 7 meters of draft. Since at least 2011, transshipment has been used in northern Australia in the export of bulk minerals including bauxite, iron ore and potash from mines in Queensland, Western Australia and the Northern Territory. As of 2020, two new transshipment export pathways are planned for South Australia. One is primarily for the export of minerals near Port Augusta and the other is for the export of wheat from Lucky Bay, South Australia, Lucky Bay. Companies providing at-sea transshipping services in Australia include the CSL Group and Transshipment Services Australia (TSA).


Transshipment at a break-of-gauge

At a break-of-gauge, cargo is transloaded from boxcars or covered goods wagons on one track to wagons on another track of a different rail gauge, or else intermodal container, containers are transloaded from flatcars on one track to flatcars on another track of a different gauge. Variable gauge, Variable-gauge axles can eliminate this inconvenience.
