Mitsubishi Chemical exits Taiwan MMA joint venture, selling KMC stake to CPDC, aiming to optimize operations and focus on competitive markets.
Mitsubishi Chemical Corporation has announced its decision to dissolve its co-ownership in Kaohsiung Monomer Company Limited (KMC), a Taiwan-based producer and supplier of methyl methacrylate (MMA) monomers. The company has reached an agreement with its joint venture partner, China Petrochemical Development Corporation (CPDC), under which Mitsubishi Chemical will transfer its entire equity stake in KMC to CPDC. Upon completion of this transaction, CPDC will assume full ownership and control of the business. The transfer is scheduled to be finalized by August 3, 2026.
This strategic move comes in response to increasingly challenging market conditions in the global MMA industry, particularly in Asia. Over recent years, the MMA market has witnessed significant competitive pressure due to rapid capacity expansions, especially in China. The addition of large-scale production facilities has led to intensified competition, oversupply concerns, and pricing pressures, making it more difficult for producers to sustain profitability. In light of these developments, Mitsubishi Chemical undertook a comprehensive review of its MMA business operations, including the long-term strategic relevance of maintaining its production base in Taiwan.
Following this evaluation, the company concluded that continuing its co-ownership of KMC was no longer aligned with its broader business objectives. As a result, it opted to exit the joint venture and transfer its 60% ownership stake to CPDC, which currently holds the remaining 40%. This decision reflects Mitsubishi Chemical’s intent to optimize its global production footprint and focus resources on areas where it can maintain stronger competitive advantages.
Looking ahead, Mitsubishi Chemical plans to reorganize and strengthen its MMA operations by consolidating manufacturing activities in regions that offer greater operational efficiency and cost competitiveness. The company also aims to accelerate its expansion into high-growth markets, leveraging its portfolio of proprietary MMA production technologies and its established presence across multiple regions. Through these measures, Mitsubishi Chemical seeks to build a more resilient and optimized production and marketing network that can better adapt to evolving market dynamics.
KMC, headquartered in Kaohsiung, Taiwan, has been a longstanding player in the MMA industry since its establishment in 1976. The company operates an MMA production facility based on the acetone cyanohydrin (ACH) method, with an annual capacity of 105,000 tonnes. Prior to this transaction, Mitsubishi Chemical held a 60% stake in KMC, while CPDC owned the remaining 40%. CPDC itself is a major Taiwanese petrochemical company, established in 1969, with a diversified portfolio that includes the production of caprolactam, acrylonitrile, and other chemical products. The company reported net sales of TWD 19.2 billion in 2025, highlighting its strong presence in the regional petrochemical sector.
The planned transfer of ownership marks a significant shift in Mitsubishi Chemical’s approach to its MMA business. By exiting the Taiwanese joint venture, the company is taking a proactive step toward reshaping its operational strategy in response to global market pressures. At the same time, CPDC’s full acquisition of KMC is expected to streamline decision-making and enhance operational efficiency for the Taiwan-based business.
Overall, this move underscores Mitsubishi Chemical’s commitment to strategic realignment, focusing on competitiveness, efficiency, and growth potential in an increasingly dynamic and competitive global MMA market.
