The current new chemical notification system came into effect on 15 Oct, 2010. In an effort to improve the regulatory system, authorities have actively solicited opinions in the later half of 2013 from industry in order to guide a revision of China’s New Chemical Substance Notification Guidance. The revision task is a sub-project of the national critical projects for chemical pollution control, managed by the Department of Pollution Prevention and Control of the MEP, undertaken by the SCC-MEP. The revision task began in Jan 2014. The draft revision was completed in Jan 2015 and then submitted for internal review by the MEP, and finally issued for public comment on 25 Jun 2015 after more than 1 year of drafting. All amendments are made in accordance with the provisions of MEP Order 7, the Measures for the Environmental Management of New Chemical Substances.
