What Heesung Catalysts Corp does

Heesung Catalysts Corp is a privately held South Korean catalyst manufacturer founded in 1983 (originally as Heesung Engelhard, a joint venture between Lucky Goldstar Group and US-based Engelhard, now part of BASF). The company is headquartered in Seoul with its primary manufacturing and R&D operations at the Siheung plant in Gyeonggi-do, described as Korea's largest integrated catalyst technology campus. Heesung designs, develops, and produces catalyst technologies across four core domains — automotive emission control (TWC, GPF, DOC, DPF, SCR, AOC, and the world's first Gasoline NOx Trap), chemical process catalysts (paraffin dehydrogenation, hydrogen production, selective hydrogenation, gas refining), environmental catalysts (PFC/N2O abatement at >99% efficiency for semiconductor and display manufacturing, VOCs/CO oxidation, SCR for marine and industrial), and electrode catalysts (PEMFC, PAFC, and PEM water electrolysis). The portfolio is supported by 354 patents, 10 advanced R&D labs, 300+ specialized analytical instruments, and proprietary capabilities in precious metal alloy design, nanostructure control, catalyst support optimization, and regeneration processes. Beyond catalysts, the company sells PGC precision gold electroplating materials (99.99% purity) for semiconductors and PCB, and dental gold alloys (34 product types) where it holds Korea's No. 1 market position in quality and sales.

Heesung operates three distinct go-to-market motions. The dominant channel is direct enterprise field sales to large automotive OEMs (Hyundai Motor Group / Kia), petrochemical plants, shipbuilders, semiconductor manufacturers, and industrial facilities, with technical support spanning design through scale-up. The Catalyst Foundry platform offers contract development, scale-up, OEM production, and licensed manufacturing for customers holding their own catalyst IP — effectively serving as Korea's only comprehensive catalyst foundry. A Catalyst Subscription Service delivers a managed, lifecycle model covering catalyst procurement, performance monitoring, regeneration, and recovery, creating recurring revenue and circular economy value. Pricing is B2B quotation-based with multi-year contracts; no public price list exists. Distribution extends globally through the BASF partnership (originating with Engelhard in 1983) and through regional channels across Asia Pacific, Europe, North America, and Southeast Asia.

Revenue is generated across catalyst hardware sales, foundry/professional services, and subscription/recurring services, with precious metal materials (PGC and dental alloys) forming a smaller but distinct fourth stream. The wholly owned subsidiary Heesung PMTech — a 2004 joint venture with Hyundai Motor Company for precious metal recycling from spent catalysts — reported KRW 6,056 billion in 2024 sales and provides vertical integration into the precious metal value chain. The company has set a Vision 2030 target of KRW 5 trillion in value-added sales and over 50% new business share by 2030, alongside an AA ESG rating target. CEO Han Hyun-sik has led the company since founding; key certifications include Hyundai Grand Quality 5-Star (2011), Hyundai-Kia Quality 5-Star (2002), the USD 1 Billion Export Tower (2021), and ISO 9001/14001/45001/22301 quality, environmental, safety, and continuity certifications.
