The complex features its own dedicated port, enabling the efficient import of raw materials and the direct export of finished products worldwide. The strategic importance of Seosan to the South Korean economy is immense, as it forms the foundation for numerous industries ranging from textiles to construction. Lately, there has been an increased focus on developing more environmentally friendly processes and researching hydrogen technologies at the site.
