The consultation process was conducted under the framework of the Act on the Examination of Chemical Substances and Regulation of Manufacture, etc., and followed procedures in line with Japan's Administrative Procedure Act. The draft proposal was originally published on 19 February 2026, with a public comment period open until 20 March 2026.

These revisions aim to improve the efficiency, clarity, and scientific robustness of chemical evaluation processes in Japan. Following the review of submitted opinions, the final results and corresponding revisions were formally announced and promulgated on 24 April 2026
