The Adriatic Border & Frontex
Tourists often view Bari as a relaxed southern Italian destination. This is a critical error. Bari is Italy’s primary maritime border with the Balkans (Albania, Greece) and is treated as a high-security international frontier.
The Guardia di Finanza (GdF) and Frontex operate with heavy mandates here. Attempting to board a ferry to Durrës or Patras with personal amounts will not be treated under the standard Article 75 for personal use, but instantly escalates to international smuggling charges.
