Companies Should Recheck Their New Chemical Registration Route Under the Revised Measures
The regulatory change and the main decision
China's Ministry of Ecology and Environment has formally issued revised measures for environmental management registration of new chemical substances. The measures take effect upon promulgation and repeal the previous version. They identify three registration routes: regular, simplified, and formal registration. Companies planning to manufacture or import a new chemical substance in China should look beyond whether it appears in the Inventory of Existing Chemical Substances in China. Before starting the activity, they need to check the intended use, projected volume, polymer criteria, and the registration certificate required for their situation.
Under the previous measures, certain low-volume cases followed a filing route. The revised measures describe the corresponding route as formal registration and require manufacturers or importers to obtain the applicable certificate before manufacture or import. Existing projects should not simply carry forward an earlier filing assessment. Companies should review their current application status and any applicable transition arrangements. This review is a compliance recommendation; the governing requirements are those in the formal measures and any supporting directions from the authority.
Choose the route by volume and substance characteristics
The principal thresholds are based on annual manufacture or import volume. Regular registration applies at 10 metric tons or more, and simplified registration applies from 1 metric ton to less than 10 metric tons. Formal registration applies below 1 metric ton and also to qualifying polymers, including those with no more than 2% monomer or reactant content and polymers of low concern. The polymer route has specific supporting-evidence requirements. A company should not infer eligibility from a product name or aggregate volume alone. Where volumes approach a threshold, applicants register jointly, or uses may change, companies should establish a consistent volume basis before selecting a route.
What changes for application preparation
A regular-registration dossier includes an application form, physicochemical and health and ecotoxicological information, an environmental risk assessment, and a signed commitment concerning risk-control measures. Simplified registration also requires specified physicochemical and ecotoxicological information and a commitment. Formal registration requires an application form and, for the specified polymer cases, evidence supporting eligibility. Companies should build a route-specific dossier checklist and assess whether existing test data support the required evaluation. Internal preparation recommendations should remain distinct from materials expressly required by the authority.
For a highly hazardous substance, regular registration additionally calls for an analysis of the socioeconomic benefits and necessity of the proposed activity. The measures also address supplementary data, technical review, certificate amendments, and circumstances requiring a fresh registration. A company planning to exceed its registered volume, switch from import to manufacture, or change the registered use or risk-control measures should review the applicable procedure before making the change. An existing certificate should not be assumed to cover every subsequent activity.
Who should reassess their position
The direct audience includes companies manufacturing or importing substances absent from the Inventory of Existing Chemical Substances in China, as well as those proposing an industrial use outside the permitted scope for an inventory substance subject to new-use environmental management. Finished products such as pharmaceuticals and cosmetics are generally outside these measures, but a substance redirected to another industrial use, or used as a raw material or intermediate for those products, still requires a scope assessment. Downstream processors should also pay attention to the certificate number, registered use, hazard information, and risk-control information passed along by suppliers.
Practical compliance steps
Companies can first verify inventory status, actual use, annual volume, and the applicant entity, then select the registration route. They can next check test data, the risk assessment, commitments, and any polymer evidence against the revised requirements, while reviewing amendments and ongoing obligations for registered projects. For existing filings or applications in progress, companies should separately verify transition and supporting documents instead of assuming that a change in route name itself completes registration. Regulix can help assess the appropriate new chemical registration route, prepare application materials, and review the compliance of technical dossiers. The registration decision remains with the competent authority.
