Grouped in bags by entry into the Euro hub, documents in small parcels of less than 500 grams are directed to the doc sort, dedicated sorting area on the upper floor. The bags are emptied, the contents identified and repackaged depending on destination. The upper floor also contains storage and repair areas for empty containers. In the hub control centre for sorting, the operation control centre and the network control centre for all air operations, the teams modulate the flow of the process, react to the unexpected, distribute resources and needs. The custom clearance department is responsible for trade and customs compliance.
