A term used by shipping lines to indicate that a ship will call at a port if there is enough profitable cargo to make the stop worthwhile.
Placing a port on a vessel's itinerary because the volume of cargo offered at that port justifies the cost of routing the vessel.
When steamship lines publish in their schedules the name of a port and the words "by inducement" in parentheses, this means the vessel will call at the port if there is a sufficient amount of profitable cargo available and booked.
