The 'Restrictions on the Manufacture, Import, and Sale of Dry Cell Batteries' (hereinafter referred to as the 'Announcement') was first promulgated on 27 March 2006, and has been revised three times, most recently on 2 March 2015. To strengthen domestic mercury management and align with the United Nations Minamata Convention on Mercury, the Ministry of Environment amended the 'Regulated Toxic Chemical Substances and Their Management Matters' in 2025 to remove the permitted use of mercury in the manufacturing of silver oxide and zinc-air button cell batteries with a mercury content of less than 2%. Accordingly, relevant provisions of the Announcement and Attached Table 1 of Item 2 will be revised.
