You can carry one package of up to five litres of Zamzam water for free in addition to your checked baggage allowance from any point of departure. It must be safely packed and labelled in a sealed plastic container, covered by a protective cardboard box. These are available to purchase at the airport.
You can only carry Zamzam water from Jeddah if you hold an Umrah or Haj visa. This applies to all guests including GCC nationals.
