Singapore is a market, a manufacturing base and a hub, and hand carry uses all three. As a market it is finance, trade, legal and arbitration, original instruments and executed documents on deadlines set by counterparties and tribunals. As a manufacturing base it is semiconductors, precision engineering, pharmaceuticals and marine and offshore fabrication, all of which generate the ordinary urgent spares and qualification traffic.
As a hub it is the best door into Southeast Asia. The onward network is deep, the formalities are among the fastest anywhere, and the land crossing to Johor and the ferry to Batam make two neighbouring manufacturing regions reachable without a second flight. For a consignment bound for Malaysia or the Riau islands, a Singapore arrival is frequently the faster and always the simpler answer.
The third point is administrative and unusually pleasant: Singapore is among the most predictable customs environments in the world. What it is strict about, it is strict about consistently, and the controlled and prohibited categories are published clearly enough to check before anyone travels rather than discover on arrival.
