If you have a house in Archeage (which is likely if you are trying to get Blue Salt bonds), you can accept a daily quest from your local community manager NPC where you need to produce one of a few local specialty trade packs. This quest is pretty straightforward; just make one of those trade packs at your local community center.
What is not required is to deliver the package. You can make the pack, store it and just go to the Speciality Buyer NPC to complete the quest. But that’s a rather expensive way to get Blue Salt bonds.
