South Korea's petrochemical industry is undergoing a significant restructuring, with local firms committing to a voluntary reduction of their naphtha cracking center (NCC) capacity by 2.7 million to 3.7 million tons, representing 18-25 percent of the nation's total capacity. This move, announced by Industry Minister Kim Jung-kwan, aims to address a severe industry-wide crisis primarily caused by global oversupply. Sixteen major petrochemical companies have submitted their initial business restructuring plans, demonstrating a concerted effort to adapt to challenging market conditions.The government is actively supporting these self-rescue efforts, promising a comprehensive support package. This includes crucial tax incentives, increased research and development (R&D) funding, and the streamlining of regulations. Furthermore, the support will facilitate the industry's transition towards high-value and eco-friendly products, aligning with global sustainability trends. The restructuring is guided by three core principles: simultaneous transformation of major industrial complexes in Seosan, Ulsan, and Yeosu; robust self-rescue plans from companies; and a holistic government support framework.Lotte Chemical Corp. and HD Hyundai Chemical have already initiated their restructuring by agreeing to spin off Lotte Chemical's NCC operations at the Daesan petrochemical complex into a new joint entity. Minister Kim urged other companies to swiftly finalize their plans, emphasizing that 2025 will be a critical year for execution. This collective effort is deemed essential for the long-term success and competitiveness of South Korea's petrochemical sector in the face of evolving global market dynamics.
