On 30 March 2026, Japan’s Ministry of Economy, Trade and Industry (METI) published the reporting procedure for existing chemicals under the Chemical Substances Control Law (CSCL) for financial year (FY) 2026. The ministry released the reporting manual on its METI portal. The reporting process is revised annually in March. 

Background on CSCL 

The aim of the Chemical Substances Control Law is to prevent environmental pollution and protect human health and ecosystems from hazardous chemicals. The law requires businesses to report the annual quantities of chemical substances manufactured or imported above specified thresholds. This data is used to evaluate the risks associated with chemicals and is part of risk management practices.

• Scope of Chemicals: General Chemicals, Priority Assessment Chemicals (PACs), Monitoring Chemicals and others. 

• Submission Methods: Electronic submission via e-Gov (requiring a G Biz ID Prime or Member account), optical disc and paper submission.
