Standard packages between 0.5 and 30 kg are sent to the upper floor that crisscross a network of the conveyor belts totalling up to 8 km. Scanners first guide the package to one or two possible output circuits, either air or road, then, direct them to a chute corresponding to the final destination within the TNT network. For illegible labels, overloaded chutes, or those requiring customs clearance, the parcel is then diverted for immediate inspection and reconditioning.
