Starting out as a state-run enterprise, TSC has sought to diversify its operations from its core salt business to comply with uninhibited private, international competition. Taiwan Salt is now divided into Seawater Chemistry, Biotech, Info-Tech, and Distribution business units based on their respective unique product lines and directions of future development.
