The Ministry of Environmental Protection (MEP) of China published two drafts for the Guidelines for Risk Assessment of Chemicals and Guidelines for Hazard Identification of New Chemical Substances and consulted publically for comments.

These documents are essential standards that provide guidance to enable fulfillment of the regular notification requirements of China New Chemical Substance Notification (China NCSN) - Measures on Environmental Management of New Chemical Substances. In line with the guidance of China NCSN, the minimum requirements for regular notification include physicochemical, toxicological and eco-toxicological test reports and a risk assessment report.

This document is a translated copy of “The Guidelines for Risk Assessment of Chemicals, China”. REACH24H Consulting Group has undertaken to translate the full Chinese legal text to help non-Chinese companies understand and comply with obligations arising from this new chemical legislation.
