More and more trade partners require shipments to be marked externally with barcodes digitally linking them to shipping notices and thus enabling a far easier and faster goods receival processes.In this case, shipping notices must include a “shipment hierarchy” that identifies every transport unit (pallet, carton, etc.) using a unique transport unit identifier. The identification system used is usually SSCC (Serial Shipment Container Code)
A single package will have a transport label printed on the physical package and list a single transport unit in digital form.PhysicalSingle SSCC on packageDigital

A shipment that consists of a single pallet will have a single transport label printed on the pallet shrink wrap. In digital form, a single transport unit is listed and the amount of cartons on the pallet is communicated via the containedTradeUnitCount parameter.PhysicalSingle SSCC on palletDigital

A pallet that is made up of multiple homogeneous “layers” (sandwich pallet) receives N+1 transport labels. One label on the shirk wrap of the whole stacked pallet and one label per layer. The same is true for the digital form: Transport units describing the different “layers” are contained within a wrapping transport unit describing the whole stacked pallet.PhysicalOne SSCC on the shrink wrap of the stacked palletOne SSCC on each sandwich layerDigital
