Everything practical about sea transit in Saudi Arabia on one page: what it costs, how long it takes, what documents decide the outcome. Modjo does the rest.
The short version: VAT stays national per destination. The GCC customs union collects the common 5% tariff once at first entry; goods then move between member states without paying duty again.

With sea transit, certificates ready before sailing beat any discount on freight.
