What Hakusui Tech Co does

Hakusui Tech Co (ハクスイテック株式会社) is a privately held Japanese specialty chemicals manufacturer founded in 1947, headquartered in Osaka, Japan. The company produces zinc oxide, zinc powder, and related inorganic materials, and self-describes as Asia's largest zinc oxide supplier. It serves industrial customers across at least seven end-markets — rubber and elastomer vulcanization, paints and anti-corrosion coatings, electronic components (notably varistors and surge protection devices), electrophotography, pharmaceuticals and cosmetics (Japanese Pharmacopeia grade), ceramics and glass, and emerging thermal-management applications. The firm also generates revenue through commissioned contract processing services spanning crushing, surface treatment/mixing, granulation, and calcination/drying.

The technology base centers on differentiated zinc-oxide variants: the 23-K series (low-cost white conductive ZnO with leading market share), the Pazet series (ultra-fine conductive ZnO — described as the only commercially successful product of its kind globally, used as an ITO/ATO replacement in transparent conductive films), ZINCOX SUPER F nano-zinc oxide (catalytic, UV-blocking, antibacterial), and SKY-Z vacuum-deposition tablet targets co-developed with Kochi University of Technology. The company also sells zirconium silicate (Micropax, Zircosyl, zircon sand) and precipitated barium sulfate (Varico) for ceramics, glass, and friction-material applications. Manufacturing is split across Japan (Chubu/Gifu and Iizuka/Fukuoka) and a wholly owned subsidiary in Zhenjiang, China (Zhenjiang Baishui Chemical Co., Ltd.).

The business model is direct B2B industrial sales with three regional sales offices (Osaka, Tokyo, Chubu) targeting enterprise customers. Pricing is not publicly disclosed and is structured around inquiry-based quotes. Product and commissioned-processing services constitute the bulk of revenue, supplemented by specialty inorganic materials. The firm operates with 101–250 employees and is led by President Toyo Izumi, with no parent company, venture backers, or public shareholders identified.
