About this page

This page announces that some imported products containing sodium aluminate have been found to contain sodium aluminum dioxide, a designated poisonous substance, according to Japan's Ministry of Health, Labour and Welfare. The affected products are concrete chemical admixtures, including "RE-CON ZERO EVO" and two others. Businesses handling these products must verify with suppliers whether they contain sodium aluminum dioxide and register as poisonous substance handlers by October 31, 2023. Information about the substance's properties and handling must be provided to distributors and users. The ministry apologizes for errors in its previous public comment response.
