Nihon Kagaku Sangyo Co., Ltd. (President: KADOYA Hiroki) is pleased to announce that the Cupric Oxide DC produced at its Saitama Plant (Soka-shi, Saitama Prefecture) completed the validation of the annual renewal of UL 2809-2* by UL Solutions Inc., as an international third-party certification body in July 2025.
 
At Nihon Kagaku Sangyo Co., Ltd., we have historically produced Cupric Oxide DC, a plating agent, from recycled materials—such as scrap coppers and used etching solutions containing copper—by utilizing our unique technology, with a view to ensuring the efficient use of metal resources.
 
As calls for a more efficient use of valuable metal resources increase globally, we will be striving even harder to contribute to the recycling of limited metal sources, by obtaining third-party validation with respect to the use of recycled materials.
 
Additionally, the Cupric Oxide DC manufactured by our consolidated subsidiary in Thailand, SIAM NKS CO., LTD., has also obtained UL certification in November 2024. (Visit website here)
 
This initiative represents a critical step toward realizing a circular society and building a decarbonized society, based on our “Medium-Term Management Plan” targeting 2030. Through further focus on recycling business, we will promote resource circulation not only within our own company but throughout the entire supply chain, contributing to the realization of a sustainable future.
