On February 1, 2024, Japan's Ministry of Health, Labor and Welfare (MHLW), Ministry of Economy, Trade and Industry (METI), and Ministry of Environment (MoE) jointly issued a draft on the revision of the Chemical Substance Control Law (CSCL) for public comments closing on March 1, 2024. This draft aims to strengthen the management of PFOA-related compounds, involving their manufacturing, import, and usage.
