On 10 January 2010, MEP revised the 2003 Measures for the Environmental Management of New Chemicals Substances (SEPA Order 17) and made the 2010 version (MEP Order 7) enter into force as of 15 October 2010.

To detail the implementation of the updated substance notification, MEP published, in the notice 124 of 2010, six supporting documents for MEP Order 7 on 16 September 2010. The most important guidance is the 2010 New Chemical Substance Notification Guidance Document. 

This guidance document was compiled according to Article 11 of MEP Order 7 in order to standardize the notification of new chemical substances and guide the notifier in completing the notification of new chemical substances.

The focus of this guidance document is on the notification procedures and categories. The guidance specifically addresses the six aspects of the Measures which are: the scope of application, notification types and submissions, notification procedure for registration, application material requirements, special provisions for polymers and the supervision and management of the registration following notification. It also describes the notification application report content, notification submission and data requirements as well as the post-registration requirements.

The main parties the guidance document is addressed to are the new chemical substance notifiers or representative agents. The notifiers or representative agents should adhere to the requirements of the guidance in order to complete new chemical substance notifications, to implement the post-registration risk control measures and to assist in the supervision and management of the new chemical substances.

The guidance document can also be consulted by the test institutes which provide the new chemical substance notification testing data and the evaluation committee who technically review the new chemical substance notification. It can also be consulted by local environmental protection branches of all levels that supervise new chemical substance management.
