INEOS has announced its decision to permanently close its ABS production site in Addyston, Ohio. The company will commence a safe and responsible decommissioning process in the second quarter of 2025.

“Over the past few years, we have seen the ABS market become increasingly competitive, particularly with growing competition from overseas imports,” said Steve Harrington, CEO of INEOS Styrolution and INEOS ABS.

“After a thorough analysis, we concluded that the substantial investment needed to continue operations and achieve profitable cost competitiveness makes this site no longer economical. This difficult yet necessary decision is driven primarily by external market conditions and is not a reflection of the performance or dedication of our team in Addyston.”

The Addyston site manufactures ABS (acrylonitrile butadiene styrene) and SAN (styrene acrylonitrile) polymers that are used in a wide variety of applications and industries, including Automotive, Household, Healthcare, and Construction. INEOS, through its Styrolution business remains dedicated to serving the North American ABS market and will continue to serve affected customers from our other production facilities in North America and within its global footprint.

“Our focus is on the future – we are taking steps to strengthen our position in the near term and ensure a strong foundation for our continued success,” Harrington continued. “We remain committed to supplying our customers with a comprehensive range of high-quality styrenic polymer grades and ensuring both global availability and local production.”
