Customs officer

Customs officers are found on Karamja, both at the port on the east side and the port in Brimhaven. You must talk to them in order to take a boat back to Port Sarim or Ardougne. It costs 30 coins.

Before you leave, they will search you for any banned substances, such as Karamja Rum. If you have any on you, it will be confiscated. Since this item is necessary in the Pirate's Treasure quest, you must find some way to smuggle it past them.

If you have an activated Ring of Charos, you can charm the Customs officers to let you ride for free.
