Founded in 1970, Taekyung Chemical is Korea's largest specialized producer of liquid carbon dioxide and dry ice, manufacturing high-purity liquid CO2 and dry ice from byproduct CO2 generated at refining and petrochemical facilities.
Revenue is split between the carbon gas business and the environmental business, with the carbon gas segment accounting for over 90 percent of total sales and standing as the core operation, as one industry report noted.
The company holds the No.1 domestic market position, with a 25 percent share in liquid CO2 and 35 percent in dry ice as of 2023, according to analyst commentary.
Unlike rivals that typically operate single plants, Taekyung runs multiple production sites and secures stable feedstock from suppliers including Lotte Chemical, LG Chem and Hanwha Total, which analysts cite as a competitive edge.
Its major end markets are diversified across shipbuilding (welding), dry ice, food and beverage, and semiconductor cleaning applications.
On the capacity front, the company completed an expansion of production facilities at its Onsan plant in January 2025 and a dry-ice production line expansion at its Daesan plant in January 2024, according to regulatory filings.
As part of the Taekyung Group, affiliates include Taekyung Eco, which produces acetylene, oxygen, carbon gas, nitrogen and other industrial gases along with environmental treatment agents, and Namyoung Electric, a lighting manufacturer.
More recently, the company has moved beyond materials sales to promote a dry-ice cleaning equipment sales business as a new growth driver, presenting a materials-centered total solution and expanding into cleaning markets for automotive, electronic components and chemical plants.
The competitive landscape features domestic carbon makers including Sinbio Chemical and Donggwang Chemical, which are reportedly planning sequential capacity additions, creating a structure where market-share competition and feedstock-securing competition coexist.
