MEE clarifies pre-manufacture and pre-import requirements for substances previously eligible for filing
China’s Ministry of Ecology and Environment has issued a notice clarifying the regulatory pathway for environmental management registration of new chemical substances. Starting August 15, 2026, China will stop processing environmental management filings for new chemical substances. Companies and other organizations that previously met the filing requirements under China’s new chemical substance rules must instead submit a registration application form before manufacturing or importing the substance. They must also provide supporting documents for the applicable circumstance, along with any information already available on the substance’s environmental and health hazards and environmental risks. The notice creates an important transition mechanism for substances that were previously handled through filing. Regulix advises manufacturers, importers, and China-based representatives to review their substance inventories, confirm whether each substance is listed in China’s existing chemical substance inventory, and prepare registration materials before production or import activities begin.
Filing will no longer be available after August 15, 2026
The most immediate change is the end of the filing pathway. From August 15, 2026, companies may no longer start a new chemical substance environmental management filing under the previous approach.
For manufacturers, importers, traders, and China-based representatives, this date should be treated as a compliance checkpoint. If a substance was previously eligible for filing, the company should now assess whether it needs to submit a registration application before manufacturing or importing the substance.
Regulix recommends that companies avoid relying only on annual volume or commercial urgency when choosing a compliance route. The first step should be to confirm whether the substance is listed in China’s existing chemical substance inventory, whether it falls within the scope of China’s new chemical substance registration rules, and whether any exemption or lower-concern pathway may apply.
Ending filing does not mean ending regulatory control
The notice does not remove regulatory obligations for substances that previously qualified for filing. Instead, it redirects those matters into a registration-based submission process.
Companies that meet the former filing-related requirements must submit a new chemical substance environmental management registration application form before manufacturing or importing the substance. They must also provide supporting materials that demonstrate the applicable circumstance under the relevant registration rules.
This distinction is important. Companies should not interpret the end of filing as permission to manufacture or import without a submission. Doing so may create compliance risks at the procurement, customs clearance, production, or customer delivery stage.
For low-volume imports, specialty chemicals, polymers, additives, and research samples, misclassification is a common risk. Regulix recommends completing substance identity confirmation first, including CAS information, polymer details where relevant, monomer composition, molecular structure, molecular weight distribution, intended use, and annual production or import volume.
Companies should prepare three core categories of materials
The notice points to three main categories of materials that companies should prepare.
The first is the environmental management registration application form for the new chemical substance. This document should accurately describe the applicant, substance identity, activity type, intended use, quantity, and other information relevant to environmental management.
The second is supporting documentation for the applicable circumstance under the relevant provision of China’s new chemical substance registration rules. These documents are used to demonstrate why the application fits the relevant regulatory pathway. Completeness, consistency, and traceability are essential.
The third is any information already available to the company regarding the substance’s environmental and health hazards and environmental risks. Even where a full testing package is not required at this stage, information already in the company’s possession should be submitted truthfully.
For imported substances, foreign suppliers may hold key information, including safety data sheets, toxicology and ecotoxicology data, degradation information, bioaccumulation data, environmental exposure details, and use descriptions. Regulix notes that an SDS alone is rarely enough for a reliable China new chemical substance assessment. Substance identity, hazard information, environmental behavior, use patterns, and exposure information often determine the quality of the submission.
Review and approval will refer to the simplified registration procedure and timeline
The notice states that the competent authority will accept and approve these submissions by referring to the simplified registration procedure and timeline. This provides a more predictable transition pathway for matters that previously used filing.
However, a simplified procedural reference should not be confused with a relaxed documentation standard. Authorities may still review whether the application materials are complete, whether the substance identity is clear, whether the supporting evidence is sufficient, and whether available hazard and risk information has been submitted.
For companies planning to manufacture or import affected substances after August 15, 2026, Regulix recommends completing three steps early: confirm whether the substance is new in China, determine whether it falls within the former filing-related scope, and verify whether the overseas supplier or upstream manufacturer can provide supporting evidence and hazard or risk information.
Submission before manufacture or import is the key compliance point
The notice emphasizes that the required materials must be submitted before manufacturing or importing the substance. This is particularly important for importers.
In practice, some companies only begin reviewing new chemical substance compliance after goods are ready to ship, already in transit, or close to customs clearance. Under the new transition arrangement, that approach carries greater risk.
If a substance is not listed in China’s existing chemical substance inventory and no exemption applies, manufacturing or importing before completing the required regulatory process may lead to shipment delays, disrupted customer deliveries, contract issues, and regulatory exposure.
Regulix recommends that companies importing chemicals from markets such as Japan, South Korea, the European Union, and the United States conduct China new chemical substance screening during the sourcing and procurement stage. For products imported in small but recurring volumes, companies should also maintain annual volume tracking and a registration-status record.
The notice is transitional, and future rules may replace it
The notice takes effect on August 15, 2026. It also states that if MEE later issues new provisions on environmental management registration of new chemical substances, those new provisions will apply and this notice will automatically cease to be effective.
This means the notice has a clear transitional function. It addresses how companies should proceed after filing is discontinued and before any further regulatory updates are issued.
Companies should therefore avoid treating the notice as a permanent, standalone rule. Instead, they should use it as the current basis for managing affected new chemical substance registration matters while continuing to monitor future regulatory updates.
Regulix will continue tracking changes to China’s new chemical substance registration system. Companies should conduct a fresh compliance review before each new production or import activity involving a substance that may not be listed in China’s existing chemical substance inventory.
Companies should build a new chemical substance registration checklist
Manufacturers, importers, and downstream users should establish an internal checklist for new chemical substance compliance. At a minimum, the checklist should cover:
- Whether the product contains any substance not listed in China’s existing chemical substance inventory;
- Whether the substance falls within China’s new chemical substance registration rules;
- Whether the substance was previously eligible for filing;
- Whether a registration application form is required after August 15, 2026;
- Whether supporting documentation is available for the applicable regulatory circumstance;
- Whether environmental and health hazard data or environmental risk information is already available;
- Whether the foreign supplier can provide substance identity, SDS, hazard data, and use information;
- Whether the production or import schedule leaves enough time for the required submission.
Overall, the notice is short but highly practical. The filing pathway will end, but the compliance obligation remains. Companies must evaluate affected substances and submit the required registration materials before manufacturing or importing them. For businesses relying on imported raw materials, specialty chemicals, polymers, additives, or research samples, early substance identification and pathway assessment will be essential to maintaining China market access and supply chain continuity.
