Time-sensitive regulatory update: China REACH / New Chemical Substance Registration

China is changing the registration framework for new chemical substances. As of 2 September 2026, the final revision of MEE Order No. 12 has not yet been published. Nevertheless, the PRC Ecological and Environmental Code, the MEE draft of 11 June 2026, the interim MEE notice effective from 15 August 2026 and changes already made to the official online system point to a clear administrative direction: a future application for an imported substance is expected to be made by an importing enterprise established in China.

This change could be particularly relevant for companies that currently export, or plan to export, chemical substances to China and either hold, rely on, or plan to obtain a China new chemical substance record notification or registration.

Companies with current or planned exports of chemical substances to China may wish to consider the following questions:

• Do you currently export, or plan to export, chemical substances to China, either as such or in mixtures?
• Do you currently hold, rely on, or plan to obtain a China new chemical substance record notification or registration for exports to China?
• If the current overseas applicant model is no longer available, could this affect your compliance route, supply-chain setup or protection of confidential business information for exports to China?

Early review recommended

As the draft includes a short timeline and may affect existing or planned China market-entry strategies, companies potentially affected by the proposed changes may wish to review their situation promptly.

For questions or an initial assessment, please contact us to discuss whether your substances, supply chain or project status may be affected.

China REACH

The MEP Order No. 7 (Measures on Environmental Administration of New Chemical Substance) came into force on October 15, 2010 and due to its similarity to the European model it is referred to as China REACH. On January 1, 2021 this was replaced by the Chinese Ministry of Ecology and Environment with MEE Order No.12 (Measures for the Environmental Management Registration of New Chemical Substances).

New Substances are substances, that are not listed in the Chinese Inventory of Existing Chemical Substances manufactured or imported in China (IECSC). These must be registered regardless of the production volume. Substances with a change in the intended use must also be registered.

A Regular Registration is required for substances that are manufactured or imported in quantities> 10 t / a. A Simplified Registration is sufficient for substances that are manufactured or imported in quantities of 1-10 t / a. For substances that are manufactured or imported in quantities <1 t / a or for polymers that meet PLC criteria (Polymers of Low Concern) a Record Notification is sufficient. In contrast to EU REACH, polymers have to be registered.

The competent authority is the Solid Waste and Chemical Management Center (SCC) of the State Environmental Protection Administration (SEPA). Registration must take place prior to production or import.

The MEE Order No.12 has resulted in the following changes in the data requirements:

• Physico-chemical test data from non-Chinese laboratories are accepted
• In-vitro skin and eye irritation studies are accepted if the results are conclusive
• Additional requirements based on P and B potential (Persistence and Bioaccumulation), e.g. toxicological data, sediment chironomid test, etc.
