Core Viewpoint - The article discusses the high barriers to entry in the MDI (Methylene Diphenyl Diisocyanate) industry, highlighting a significant shift in market dynamics with a Chinese company emerging as a leader, surpassing traditional international giants like BASF and Covestro [3][4]. Industry Analysis - MDI is recognized as one of the most complex products in the chemical industry, with its industrial production limited to the liquid-phase phosgene method, which is complicated and poses environmental challenges [3]. - The production process of MDI involves significant technical barriers, including high toxicity and substantial hydrochloric acid byproduct, deterring many potential entrants [3]. - According to the Ministry of Industry and Information Technology, new MDI facilities must have a minimum capacity of 300,000 tons per year, requiring investments exceeding 6 billion yuan, which is a substantial hurdle for small and medium-sized enterprises [3]. Market Dynamics - Currently, there are only about eight companies globally capable of MDI industrial production, indicating a highly concentrated market with little new competition entering [4]. - A notable shift is occurring in this concentrated market, with a Chinese company rapidly gaining market share and positioning itself as the global leader in MDI production, outpacing established players like BASF and Covestro [4].
