Customs officers are found on Karamja, both at the port at Musa Point and the port in Brimhaven. The player must talk to them in order to take a boat back to Port Sarim or Ardougne. It costs 30 coins to depart. If a player is wearing the Karamja gloves, the cost is lowered to 15 coins.
Before the player leaves, they will search the player for any banned substances, such as Karamjan rum. If the player has any on themselves, it will be confiscated. Since this item is necessary in the Pirate's Treasure quest, the player must find some way to smuggle it past them.
If the player has an activated ring of charos, the player can charm the customs officers into letting the player ride for free.
