Why is Asahi Kasei considering selling or partnering on its South Korea ACN operations?

Asahi Kasei is considering seeking partners or buyers for its South Korea ACN operations because the ACN business is highly cyclical and fluctuating, which conflicts with the company’s strategic shift away from capital-intensive, volatile basic chemicals toward high-growth sectors like healthcare and housing; CEO Koshiro Kudo stated that while the Ulsan plant is 'very strong relatively in the world,' its volatility makes it unsuitable for long-term investor confidence, especially as basic chemicals now account for only 5% of Asahi Kasei’s total business.

What is Asahi Kasei’s broader strategy for its ACN production amid Japan’s petrochemical industry restructuring?

Asahi Kasei is systematically reducing domestic ACN production—discontinuing the 200,000 tonne/year line at Mizushima Works by FY2030—and converting part of its MAN capacity to co-produce ACN and MAN, while relying on its wholly owned subsidiary Tongsuh Petrochemical in South Korea to continue fulfilling ACN supply; this reflects a larger corporate pivot from cyclical basic chemicals to specialty materials, housing, and healthcare, aligned with Japan’s industry-wide consolidation driven by demographic decline and competitive pressure from China’s expanding and increasingly high-value petrochemical sector.
