A Terminal Operating System, or TOS, is a key part of a supply chain and primarily aims to control the movement and storage of various types of cargo in and around a port or marine terminal.

The Seatrade Group’s associated companies are by far the largest cargo handling, stevedoring, and terminal operators at Port Qasim, dominating bulk cargo handling in Karachi Port. The Group handles an average of 3.500 to 4.000 million tons annually and owns and operates the largest fleet of pneumatic vacuvators, hydraulic and electro-pneumatic clamshell grabs, automatic high-speed bagging plants, and dumper trucks.
