Delivered At Frontier (DAF)
  
Delivered at Frontier is a shipping term that has lapsed into disuse, referring to delivery at a specified border location.
Maritime shipping to ocean ports obviously does not logistically have the capability to deliver to landlocked countries, so an exporter who agreed to ship DAF will have also arranged inland shipping to deliver to the border location of the nation where the goods were to be received. This could be due to customs restrictions of the receiving nation, or because the goods were going to a war zone, for example.
DAF has since been generally supplanted by the terms Delivered at Terminal (DAT) or Delivered at Place (DAP).
