What the cluster does
Charleston competes directly with Savannah for South Atlantic container volume and has invested heavily in harbour depth to take larger vessels on more tides. The port is efficient and modern, with the Leatherman terminal adding capacity, and the trade is overwhelmingly containerised rather than bulk or energy.
- Deep harbour after federal deepening
- Modern container terminals
- South Atlantic gateway
- Strong inland rail links
