When a ship is cleared by the customs authorities on arrival in Argentina bunkers, paints, chemicals and spare parts are required to be declared on the ship's store list. Lack of declaration and inaccuracies will constitute "prima facie" an infringement of customs regulations.
Ship's agents are jointly and separately responsible for this sort of infringement since proceedings are instigated against them as "clearance agent". Therefore, the ship agent will require a letter of undertaking before ship's departure from Argentinean waters covering themselves for the potential fine up to its maximum exposure.
