China REACH (MEE Order 12)
China REACH Substance Registration and Compliance Services
Place New Chemical Substances on the Chinese Market with Confidence with China REACH (MEE) Registration Services by GPC
Before entering the Chinese market, companies must determine whether their substance is listed in the Inventory of Existing Chemical Substances in China, commonly known as the IECSC.
If a substance isn’t found in the IECSC, it’s usually thought of as a new chemical substance. What happens next depends en a few things: how much of it is made or imported each year, its properties, whether it’s a polymer, y what it’s going to be used for. Based on these factors, it might need to have a record filed, go through a simplified registration process, o get a regular registration before it can be made o brought into the country.
GPC helps companies for China REACH (MEE) Registration Services from other countries, like manufacturers, exporters, y traders, as well as Chinese importers, con el whole China REACH compliance process . China REACH substance registration includes checking if a substance is on the IECSC list, coming up with a registration plan, submitting el necessary documents, y managing everything after registration. They support these companies every step of the way, making sure they follow all the rules and regulations.
What Is China REACH?
China REACH: A Brief Overview – Industry terms – EuChemS
En law for China REACH es called Measures for the Environmental Management Registration of New Chemical Substances, MEE Order No. 12.
MEE Order No. 12 of 2020, which became effective en January 1, 2021, replaced the MEP Order No. 7 of 2009 for Environmental Management New Chemical Substances Registration and requires the filing or registration by fabricantes o importers of new chemical sustancias prior to their production or introduction into the market in China.
China REACH es managed by el Chinese Ministry of Ecology and Environment (MEE).
Important 2026 Regulatory Update
MEE recently issued nuevo measures for el registration of chemical sustancias for público comment. The comment period for el proposed changes closes en 11 June 2026.
The proposed changes may affect areas such as:
- Registration applicants and China-based agents
- Registration and filing pathways
- Exemptions and exclusions
- Polymer requirements
- High-hazard substances
- Supply-chain obligations
- Post-registration supervision
- Legal liabilities and penalties
The consultation closed on 12 July 2026.
The revised measures have not yet been adopted by el MEE and we recommend that companies continue a operate in accordance with the existing measures as set out in MEE Order No. 12 whilst we monitor the progress of the proposed revision.
We continue a monitor the developments and inform you en el possible impact for future registrations, existing certificates and your polymer portfolio.
Who Must Comply with China REACH or MEE Order No. 12 registration ?
China REACH legislation apply to within organizations involucrado con new chemical substances in China (i.e., manufacturing, importing, exporting, using of new substances)
Potentially affected companies include:
- Chinese chemical manufacturers
- Chinese importers
- Overseas chemical manufacturers
- Overseas formulators
- Overseas trading companies
- Exporters supplying chemicals to China
- Companies introducing new polymers
- Importers of mixtures containing new substances
- Importers of articles designed to release new substances
Proposing a new industrial use for a controlled existing chemical substance.
En obligations of China REACH are defined by four elements: el chemical identity in question, el annual amount of the substance in question, el intended use or new function of the substance in question, y el role of el company in the supply chain of that chemical substance in question.
IECSC Checking
The Inventory of Existing Chemical Substances in China (IECSC) es a list of chemical substances which have been recorded prior to the implementation of the law relating to the registration of new chemicals in China, and is used to distinguish between nuevo chemicals and existing chemicals for purposes of chemical registration.
Substances listed on the IECSC are considered to be already existing en stock in China. These chemical sustancias son usually no required a ser registered as new chemical substances even if they are to be manufactured or imported into China. However, such existing chemical sustancias could ser subject to environmental control measures for new use.
The IECSC includes:
- A publicly available inventory
- Confidentially listed substances
- Substances subject to new-use controls
- Eligible substances added following regular registration
- The MEE periodically updates the IECSC inventario of chemical substances that have already been registered in China and publishes lists of newly added substances y of substances that are proposed for addition after the update has been conducted.
- Public IECSC search
- The initial search may use:
- Número CAS
- Chinese chemical name
- English chemical name
- Molecular formula
- Substance identity information
- Confidential IECSC inquiry
- Even if a substance es no en el público IECSC list, it might be in the confidential part of the inventory.
- Distinguishing between sustancias included en el confidencial part of el inventario y those no included en the inventory at all even if publicly unknown is sometimes necessary and puede prevent unnecessary efforts for new chemical registration, testing, y related work as well as avoid associated expenses and delays.
GPC IECSC services
GPC can support:
- Public inventory screening
- Substance identity review
- Confidential IECSC inquiry
- Interpretation of search results
- New-use control screening
- Written regulatory status confirmation
Can an Overseas Company Register?
- A supplier from overseas, be it a manufacturer or trading company, puede ser the registration applicant for a new chemical for export to China.
- In cases where a single overseas manufacturer or trading company wants to register a nueva sustancia química for export to China, they puede act as the registration applicant. However, el overseas manufacturer or trading company has to appoint a registered legal entity in mainland China as su agent. The overseas applicant and el agent registered in mainland China jointly carry out the registration and post-registration procedures and their obligations afterwards.
- An overseas manufacturer or trading company would typically register through their overseas company. En overseas company would then appoint a China-based entity (e.g. GPC) as su agent y el overseas applicant and their China-based agent would jointly regístrese en el chemical substance y perform el subsequent post-registration obligations.
GPC can assist with:
- China REACH Only Representative
- Power of Attorney documentation
- Application preparation
- Regulatory submission
- Authority communication
- Certificate management
- Post-registration reporting
- Supply-chain communication
Tipo de registro
MEE Order No. 12 establishes three main registration pathways, together with specific compliance routes for qualifying polymers and new uses of certain IECSC-listed substances.
| Compliance Pathway | Application Scope / Description |
|---|---|
| General Application | |
| Record filing | New chemical substances manufactured or imported in quantities of less than 1 tonne per year. |
| Simplified registration | New chemical substances manufactured or imported in quantities from 1 tonne to less than 10 tonnes per year. |
| Regular registration | New chemical substances manufactured or imported in quantities of 10 tonnes or more per year. |
| Polymer record filing | Polymers containing no more than 2% by weight of new monomers or reactants, and qualifying polymers of low concern that meet the applicable criteria. |
| New-use registration | IECSC-listed substances are subject to new-use environmental management controls when they are intended for a use outside the permitted scope. |
Notificación requirements son no only determined by the amount of tonnage of a substance, pero also by several additional criteria.
- Substance identity
- Polymer composition
- Intended use
- Hazard profile
- Persistence and bioaccumulation
- Environmental exposure
- Existing test data
- Confidentiality requirements
- Supply-chain structure
Article 10 of MEE Order No. 12 of el MEPC sets out el thresholds for el relevant categories as well as the principal registration categories.
Documento de registro
Inventario
The Inventory of Existing Chemical Substances in China (IECSC) was introduced in 2013. The list has been regularly updated since then. Currently, there are 46,192 listed chemical substances as of the latest updates (Latest reference date 2020-11-17). Substances in the inventory are presented as category names, neither CAS number nor molecular structure is given. Substances that are not listed in the Inventory are considered Nueva sustancia química.
El Inventario consta de dos partes (público y confidencial). Actualmente hay 3.270 sustancias confidenciales. Las empresas deben presentar una solicitud formal para comprobar si una sustancia figura en la parte confidencial. El Centro de Gestión de Residuos Sólidos y Productos Químicos de China (SCC), una división de MEE, emitirá entonces una carta de confirmación (normalmente en 2 semanas) y se cobrará una tasa de 3 000 RMB. GPC puede atender la consulta en nombre del cliente.
A pesar de que todos los monómeros figuran en el inventario, sigue siendo necesario registrar los polímeros.
Informe anual
Primer informe de actividad
Los titulares de certificados o sus RUP, independientemente de los tipos de registro, tienen que presentar los primeros informes de actividad en un plazo de 60 días desde la primera actividad (fabricación e importación/transferencia al usuario intermedio) de las sustancias químicas en cuestión.
El informe debe contener la siguiente información:
- Información de la empresa importadora o productora nacional
- Hora, lugar y volumen de la primera actividad
- Información del usuario transferido
- Medidas de control de riesgos medioambientales
- Aplicación de los requisitos de gestión medioambiental
Informe anual
Los titulares de certificados de registro ordinarios o sus RUP de los anotados con obligación de Informe Anual en sus certificados tienen que presentar Informes Anuales antes del 30 de abril a partir del segundo año de registro.
El informe anual debe incluir la siguiente información:
- Registro de las actividades de las nuevas sustancias químicas desde el año pasado, incluido el volumen de producción o importación, el historial de transferencias y la información sobre los usuarios del tratamiento.
- Registro sobre comunicación de información
- Emisión al medio ambiente
- Medidas de control de riesgos medioambientales
- Aplicación de los requisitos de gestión medioambiental
Nota: los usuarios del tratamiento están obligados a ayudar a los titulares de los certificados a cumplir con la obligación del informe anual.
Are Polymers Exempt?
No. Unlike EU REACH polymers are not automatically excluded from new chemical substance requirements in China for existing substances not listed in IECSC.
For chemicals que son not listed in the IECSC a polymer assessment needs to ser performed in order to determine the corresponding measures to be taken in order to fulfill the legal requirements for new chemical substances.
Certain polymers may qualify for record filing, including:
Polymers que contain no more than 2% by weight of new monomers or of reactants used in the polymerisation.
A polymer assessment may require information on:
- Monomers and reactants
- Weight percentages
- Number-average molecular weight
- Molecular-weight distribution
- Oligomer content
- Functional groups
- Cationic properties
- Polymer stability
- Residual monomers
- Structural information
Information obtained from the GPC measurement puede be used to assess whether a polymer has a degree of concern low enough to enable record filing or whether it will require simplified or full registration.
China REACH Compliance Process
1. Confirm the substance identity
Define the substance (chemical name) y provide identifiers for el substance such as the CAS number, molecular formula and 2D structure. Also, provide information on the substance’s purity, and any impurities o additives that are present in the substance.
2. Search the IECSC
Public database search (IECSC public inventory). Is a confidential inquiry required?
3. Confirm the regulatory scope
Are the substance and intended utilisar covered by the scope of the MEE Order No. 12 or son they excluded o subject to another exception or special case?
4. Identify the compliance pathway
Determine whether a substance has to be registered by record filing, simplified registration, regular registration or new-use registration.
5. Conduct a data-gap analysis
Compare the information you have with the technical requirements for registration in el relevant category of registration.
6. Develop a testing strategy
Determine whether it is possible to rely on existing knowledge (e.g. reports, literature) or whether a read-across, a QSAR calculation, a weight-of-evidence assessment etc. has a ser performed before new tests can be conducted.
7. Prepare the dossier
Application forms; Information on el registered substance; Study summaries; Evaluations; Assessments as required by the appropriate registration procedure.
8. Appoint the China-based agent
Overseas applicants would also need to prepare agent appointments and Power of Attorney documentation.
9. Submit the application
Step 9: Submit the filing or registration application (for overseas applicants’ agents to submit on their behalf through the MEE system(s) as required, respond to any MEE review queries and follow up until the processing is completed).
10.Complete post-registration obligations
Complete post registration requirements i.e. reporting, communicating, keeping records y managing risks as required by applicable requirements.

According a MEE Order No. 12 the technical-review periods are as follows:
Up to 30 days for simplified registration
Up to 60 days for regular registration
Time spent by the applicant to compile supplementary información (such information is no part of the formal review period granted by MEE Order No. 12) y time required a carry out any necessary laboratory testing plus time required a complete el registration dossier.
Companies should start to assess the required substances for su products before the first manufacture or import date.
China REACH does not cease to require actions of compliance after a registration certificate or a filing receipt has been obtained.
Supply-chain communication
Information of registered or filed use of substances of very high concern (SVHC) by manufacturer, importador o processing user has a ser communicated to other parties in the supply chain after registration certificate or filing receipt has been obtained by such manufacturer, importador or processing user.
- Registration certificate or filing receipt number
- Registered or filed use
- Environmental and health hazards
- Environmental risk-control measures
- Applicable environmental management requirements
Record keeping
Companies must maintain records of:
- Activity dates
- Manufactured or imported quantities
- Uses
- Risk-control measures
- Environmental management requirements
Records must generally be retained for:
- 10 years for substances subject to registration under simplified o regular procedure.
- At least three years for record filings
First activity reporting
En first activity report of holders of simplified or regular registration certificates has a ser submitted within 60 days of the following events:
- First manufacture; or
- First import and transfer to a processing user
- A first activity report as required for registered sustancias under Article 41 is not required for sustancias filed under Article 40.
Annual reporting
Annual reporting for registered substances does no apply a all of them.
Annual reporting for substances registered on el basis of regular registration es only required if el regular registration certificate includes environmental management requirements for annual reporting. In such cases the report must be submitted by 30 April of el year following the previous calendar year.
New hazard information
Any nuevo information concerning potential health o environmental effects has a be reported immediately to REACH if in the notifier’s opinion this information indicates an increased risk for the environment. Appropriate action has a be taken by el notifier en el case of such increased risk.
Confidential Business Information Protection
Applicants puede apply for the protection of su confidential information as filed during el Inscripción o Filing process.
A confidentiality request should:
- Identify the information requiring protection
- Explain why confidentiality is necessary
- Describe the potential commercial harm caused by disclosure

Frequently Asked Questions
1. What is China REACH?
China REACH is the commonly used industry term for China’s regulatory framework governing new chemical substances.
The principal legislation currently in force is the Measures for the Environmental Management Registration of New Chemical Substances, commonly known as MEE Order No. 12.
MEE Order No. 12 was issued in 2020 and entered into force on 1 January 2021, replacing the former MEP Order No. 7 of 2010.
2. How can I check whether a substance is listed in the IECSC?
The Inventory of Existing Chemical Substances in China, or IECSC, is used to determine whether a chemical is considered existing or new in China.
A public IECSC search can be conducted using available identifiers such as:
- Número CAS
- Chinese or English chemical name
- Molecular formula
- Other relevant substance identity information
If the public search result is unclear or the substance cannot be found, a formal confidential IECSC inquiry may be required. This is important because some substances are included in the confidential portion of the inventory and cannot be identified through the public list.
3. What happens if a substance is not listed in the IECSC?
A chemical substance that is not listed in the IECSC is generally considered a new chemical substance in China.
The substance must complete the applicable record-filing or registration procedure before it is manufactured in or imported into China.
The required compliance pathway depends on factors such as:
- Annual manufacture or import quantity
- Polymer status
- Intended use
- Hazard characteristics
- Applicable new-use controls
4. Does a substance below one tonne per year require China REACH compliance?
Yes.
A new chemical substance manufactured or imported in a quantity of less than one tonne per year is not automatically exempt from China REACH.
It will generally require record filing before manufacture or import, unless a specific exemption or exclusion applies.
5. Does an overseas company need a China-based agent?
Yes.
An overseas manufacturer or trading company acting as the registration applicant must appoint a legally established entity in mainland China as its agent.
The overseas applicant and the China-based agent are responsible for fulfilling the applicable registration and post-registration obligations.
The China-based agent is sometimes commercially referred to as a China REACH Only Representative, although MEE Order No. 12 formally uses the term agent.
6. Are polymers exempt from China REACH?
No. Polymers are not automatically exempt from China REACH.
A polymer that is not listed in the IECSC must be assessed to determine the applicable compliance pathway.
Certain polymers may qualify for record filing, including:
- Polymers containing no more than 2% by weight of new monomers or reactants
- Qualifying polymers of low concern
- Polymers that do not meet the record-filing criteria may require simplified or regular registration, depending on the annual quantity and other relevant factors.
7. Are mixtures covered by China REACH?
Mixtures are generally assessed at the individual substance level.
Each chemical substance contained in a mixture should be checked against the IECSC. Any component that is considered a new chemical substance must complete the applicable filing or registration procedure before the mixture is manufactured in or imported into China.
8. Is testing always required?
Not necessarily.
The testing and data requirements depend on the applicable compliance pathway and the information already available for the substance.
existing information may be considered where it is sufficiently reliable and relevant, including:
- Existing study reports
- Scientific literature
- Read-across data
- QSAR results
- Weight-of-evidence assessments
- Other scientifically justified information
However, simplified and regular registrations have specific data requirements. Certain ecotoxicological data may also need to meet Chinese testing requirements and include studies conducted using Chinese test organisms.
A data-gap analysis should therefore be completed before commissioning new studies.
9. How long does China REACH registration take?
Under MEE Order No. 12, the formal technical-review periods are generally:
- Up to 30 days for simplified registration
- Up to 60 days for regular registration
These periods do not include the time required to:
- Confirm the substance identity
- Conduct an IECSC inquiry
- Generate laboratory data
- Prepare the registration dossier
- Translate supporting documents
- Respond to requests for supplementary information
The total project timeline may therefore be considerably longer, particularly when new testing is required.
10. What happens after China REACH registration?
Post-Registration Obligations
Compliance obligations continue after a registration certificate or record-filing receipt has been obtained.
Depending on the applicable registration pathway and the conditions specified in the certificate, companies may be required to fulfil the following obligations.
Communicate Information Downstream
Manufacturers, importers and processing users must communicate relevant information to downstream recipients, including:
- Registration certificate or record-filing receipt number
- Registered or filed use
- Environmental and health hazard information
- Environmental risk-control measures
- Applicable environmental management requirements
Maintain Activity Records
Companies must maintain records of activities involving the new chemical substance, including:
- Manufactured or imported quantities
- Uses of the substance
- Downstream recipients
- Implementation of environmental risk-control measures
- Compliance with applicable environmental management requirements
Records must generally be retained for:
- At least 10 years for simplified and regular registrations
- At least 3 years for record filings
Submit a First Activity Report
A holder of a simplified or regular registration certificate must generally submit a first activity report within 60 days of:
- The first manufacture of the substance; or
- The first import and transfer of the substance to a processing user
Submit Annual Reports Where Required
Annual reporting is not required for every registered substance.
It applies where an annual-reporting obligation is specifically included in the regular registration certificate. Where required, the annual report must generally be submitted by 30 April and cover activities conducted during the previous calendar year.
Report New Hazard Information
Any newly identified environmental or health hazard information relating to the substance must be reported promptly.
Where the new information indicates an increased environmental risk, the company must take appropriate measures to control or reduce that risk.
