HAYASHI KASEI KOREA

What HAYASHI KASEI KOREA does

HAYASHI KASEI KOREA CO., LTD. (하야시카세이코리아) is a privately held Korean industrial mineral supplier and wholly-owned subsidiary of Japanese HAYASHI KASEI CO., LTD., headquartered in Osaka. Originally established in January 2005 as 한국에이치케이통상 (Korea HK Trading Co., Ltd.) and renamed in February 2011, the company operates from a single Seoul office (Seocho-gu) with a seven-person headcount, importing and distributing a focused portfolio of three industrial mineral product lines: talc (탈크), heavy calcium carbonate (중질 탄산칼슘), and aluminum hydroxide (수산화 알루미늄). The products serve Korean manufacturers in resins, paints and coatings, rubber, ceramics, construction materials, adhesives, and flame-retardant applications.

The underlying technology centers on advanced industrial mineral processing and surface treatment, including controlled particle-size grinding, classification, and chemical surface modification. The talc line features the proprietary MICRON WHITE® series with high whiteness (CIE L* 93–95) and the KHP series with compressed variants. The calcium carbonate line ranges from standard FP/KS grades to the ultra-fine ESCARON series (down to 1.7μm particle size, surface area up to 23,000 cm²/g) and fatty-acid surface-treated SST/SCP variants. The aluminum hydroxide line covers general-purpose C-12/C-31 grades and high-whiteness CW-series grades, leveraging endothermic decomposition for flame retardancy in resins, papers, and electrical/electronic components.

The business model is a quote-based B2B direct sales operation targeting Korean enterprise manufacturers, with products supplied from parent-company production in Japan. Distribution is single-channel direct sales within Korea, supplemented by a basic inquiry-based website; the company does not disclose pricing, employs no enterprise software/API platform, and has no public capital structure beyond its parent relationship. Customer segmentation is horizontal across use cases, with named end-application categories rather than named customer accounts.
