China REACH is the common name for China’s new chemical substance registration regime. On 24 October 2026, China’s Ministry of Ecology and Environment (MEE) issued MEE Order 40, the revised Measures for the Environmental Management Registration of New Chemical Substances, which took effect the same day and repealed the previous MEE Order 12. For global manufacturers sourcing chemicals and components from China, this is not a cosmetic update. It restructures who may register, which activities are in scope, and how the former filing route works. If you want to understand your current exposure, a compliance review is a practical first step.

Key Takeaways

• MEE Order 40 took effect on 24 October 2026 and repealed MEE Order 12, completing China’s alignment with the new Ecological and Environmental Code.

• Overseas manufacturers and traders can no longer register directly or through a designated local agent. Only China-based manufacturers or importers may now apply.

• Order 12’s tonnage thresholds are retained. Record filing is replaced by a formal (pro forma) registration under administrative approval.

• The reform reaches deeper into your Chinese supplier base, shifting registration responsibility onto the China-based entity that manufactures or imports.

• Existing Order 12 certificates and pre-15 August 2026 filing receipts remain valid, but changes trigger re-registration by an eligible China-based applicant.

• Core sectors affected include chemicals, electronics, automotive, batteries, and any manufacturer importing new substances into China.

What Is China REACH, and What Changed Under MEE Order 40?

Under China REACH, a chemical substance is treated as “new” if it is not listed in the Inventory of Existing Chemical Substances in China (IECSC). A new substance generally requires environmental management registration before it is manufactured in, or imported into, China. This is conceptually similar to the EU regime covered on Certivo’s REACH framework page, but it is a distinct Chinese system with its own inventory, authority, and procedures.

MEE Order 40 is the revised version of that regime. It was published and enacted on 24 October 2026 and immediately superseded MEE Order 12, which had been in force since 1 January 2021. The change is documented in the U.S. Department of Agriculture’s official report on the notified Measures and in MEE’s own press responses. Manufacturers managing chemical and hazmat compliance should treat this as a material regulatory event, not a routine renumbering.

The Legislative Shift: From Order 12 to a Statutory Code

The most structural change sits above the Order itself. China’s Ecological and Environmental Code took effect on 15 August 2026 as statutory law, and it writes the registration obligation and the penalties for non-compliance into statute. MEE Order 40 is the departmental regulation that implements that Code. In practice, that elevates the legal weight behind the registration duty and the enforcement consequences for getting it wrong.

What MEE Order 40 Changes for Manufacturers

Four changes matter most for compliance, procurement, and supply-chain teams. Each one affects how substance data moves through your supplier base and where registration responsibility now sits.

Record Filing Replaced by Formal Registration

Under Order 12, registration had three routes: regular registration, simplified registration, and record filing. Record filing covered volumes below one tonne per year and certain polymers, and it issued an automatic receipt with low data requirements. Order 40 removes that automatic filing route and brings those submissions under formal administrative approval. Importantly, as Keller and Heckman’s legal analysis confirms, Order 40 did not adopt the June draft’s proposed new thresholds. The existing Order 12 tonnage bands remain in place.

Based on currently available regulatory guidance, data and testing requirements within each tonnage band remain broadly consistent with Order 12, so the data-gathering burden per dossier is largely unchanged. The administrative pathway, not the data depth, is what shifts.

Overseas Companies Can No Longer Register Directly

This is the single most consequential change for international supply chains. Article 11 of MEE Order 40 limits applicants to entities legally registered in China that can independently assume legal liability and that manufacture or import the substance. The former option, where an overseas manufacturer or trader applied through a designated Chinese agent, has been removed. A local service provider does not automatically qualify simply by being located in China. Teams managing supplier and contractor relationships will feel this immediately, because registration responsibility now rests with the China-based manufacturer or importer.

Narrowed Scope: Manufacture and Import

Order 12 applied to research, production, import, and processing or use. Order 40 defines the registration scope as the manufacture or import of new chemical substances in China. Entities engaged solely in research and development, or solely in processing and use, are no longer registration applicants, although processing and use companies retain environmental management responsibilities. Research use does not, by itself, exempt a substance from registration. This narrowing clarifies responsibility but concentrates it on the parties placing substances into Chinese production or import.

Exemptions Retained

MEE Order 40 retains Order 12’s exemptions for pharmaceuticals, veterinary drugs, cosmetics, food, food additives, feed, feed additives, and fertilisers. The June draft had proposed removing some of these, so their retention is a meaningful relief for affected sectors, with some boundary adjustments for pharmaceuticals and agrochemicals.

What Happens to Existing Registrations and Filings?

MEE applies a non-retroactivity principle. Registration certificates lawfully obtained under MEE Order 12 (and under the former MEP Order 7), and record-filing receipts acquired before 15 August 2026, remain fully valid. The catch is change management. If the details in a record-filing receipt or an overseas enterprise’s certificate change, a fresh registration must be submitted by an eligible China-based applicant that meets Order 40’s requirements, as set out in MEE’s own press responses on the revised Measures. For auditability, that makes point-in-time records of what was registered, by whom, and when, a practical necessity rather than a nice-to-have.

Why This Reaches Deeper Into Your Chinese Supplier Base

If you import finished goods, formulations, or components from China, the registration obligation sits with your Chinese suppliers, but the commercial risk sits with you. A supplier that cannot lawfully register a new substance cannot lawfully place it into Chinese production or import, which can disrupt the materials feeding your products. The same pressure that tariffs and reshoring have already put on material documentation now extends to new substance status inside China.

The core difficulty is visibility. Most manufacturers do not know, at the bill-of-materials level, which substances in their sourced inputs are IECSC-listed and which are “new.” Answering that question across a multi-tier supplier network is a data problem, and it is the same problem that multi-tier electronics supply chains face with every chemical rule change. Mapping substances to parts, and parts to suppliers, is where BOM-level compliance tracking becomes decisive.

If your materials documentation depends on suppliers relaying substance information, structured collection matters. Automated supplier data collection replaces email chasing with guided requests, and consistent capture supports broader materials and environmental compliance across jurisdictions.

Struggling to confirm which substances in your China-sourced inputs are IECSC-listed? A focused compliance review can map your current China REACH exposure before it affects production.

Executive and Compliance Implications

For the CEO and board, the exposure is continuity of supply and market access, since a supplier’s inability to register can halt the flow of a sourced material. For the CFO, the implications are the cost of re-registration, agent transitions, and potential qualification of alternate suppliers. For compliance and regulatory teams, the work is substance screening against IECSC, confirming applicant eligibility, and tracking the transition status of existing certificates. For supply-chain and procurement leaders, it is supplier data, multi-tier visibility, and material mapping. Treating these as one connected dataset, rather than separate spreadsheets, is what proactive compliance risk management requires.

How to Prepare: A China REACH Readiness Approach

1. Screen your China-sourced substances against IECSC. Identify which inputs contain substances that are “new” and therefore in scope for registration.

2. Confirm applicant eligibility with each supplier. Verify that a China-based manufacturer or importer holds, or will obtain, the registration under Order 40.

3. Review existing certificates and filings for change triggers. Any change to a certificate or an overseas-held registration may require fresh registration by an eligible applicant.

4. Map substances to your bill of materials. Connect substance status to parts and suppliers so impact is visible at the product level.

5. Centralise supplier evidence. Replace ad hoc requests with structured, repeatable collection that produces audit-ready records.

6. Monitor for transition guidance. MEE is expected to issue further transition documents, so horizon scanning should stay active.

This is where Certivo functions as the system of record. CORA-powered regulatory intelligence supports horizon scanning across frameworks, while BOM-level substance mapping and supplier portals turn scattered declarations into a single, queryable compliance backbone. For manufacturers that also track the EU regime, the same discipline underpins REACH recast readiness and supports chemical manufacturing teams managing overlapping obligations. The goal is not to make compliance risk disappear. It is to reduce surprises, speed evidence retrieval, and keep teams audit-ready.

Extend supplier data collection into your China supply chain. Request a compliance review to see where your China REACH exposure sits across products, substances, and suppliers.
