HAF 604 Certification for Nuclear Safety Equipment & Components
HAF 604 Certification for Nuclear Safety Equipment and Components is a mandatory requirement for foreign manufacturers supplying civil nuclear safety equipment, safety-related components, and other nuclear safety equipment to China. This certification ensures that imported civilian nuclear equipment meets the rigorous standards set by the National Nuclear Safety Administration (NNSA) before being installed in Chinese nuclear power plants and other nuclear facilities.
This certification process involves a comprehensive technical review and an on-site factory inspection (which may be exempted) conducted by Chinese nuclear safety authorities. It is one of the most stringent and essential steps for international suppliers in gaining market access in the Chinese nuclear power industry.
All imported civilian nuclear equipment and components for use in nuclear power plants must undergo HAF 604 Certification to meet Chinese regulations. This applies to a wide range of systems, including mechanical assemblies, safety valves, and nuclear safety components.
Foreign companies often face challenges entering the Chinese market, such as language barriers and navigating quality management regulations. The HAF 604 journey typically involves initial certification, active participation in Chinese nuclear projects, and evidence of continued compliance; each crucial for maintaining and renewing the certification over time.
Understanding HAF 604 Certification
HAF 604 Certification for Nuclear Safety Equipment and Components is a license issued by the National Nuclear Safety Administration (NNSA), under the Ministry of Ecology and Environment (MEE). It applies to foreign manufacturers of nuclear safety equipment and safety-related components intended for Chinese nuclear facilities.
To obtain the certification, manufacturers must undergo a thorough qualification process that includes:
This certification extends beyond manufacturing entities. Designers of nuclear safety components must also apply separately, further highlighting the strict supervision required under the management regulations. This underlines the stringent guidelines inherent to the HAF 604 protocol intended to sustain top-tier security measures in nuclear energy generation settings as well as within systems involving safety valves.
History & Background
The HAF system was established in the early 2000s to control imports of safety equipment and materials for nuclear power projects. HAF 601 applies to domestic manufacturers, while HAF 604 governs international suppliers. The system strengthens supervision and ensures compliance with evolving regulations.
While the CCC system focuses on general product safety, the HAF system specifically governs safety-critical items used in nuclear reactors and related facilities, making it one of the most demanding certifications in China’s regulatory landscape.
HAF Regulatory Framework
The detailed stipulations for obtaining HAF 604 certification can be found within the Supervision and Management Regulations for Imported Civilian Nuclear Equipment. The following institutions are involved in supervising and regulating the HAF system:
Who Needs HAF 604 Certification?
HAF 604 is required for non-Chinese manufacturers that supply:
This includes both civil nuclear safety equipment and other critical systems intended for nuclear facilities manufactured outside China.
The HAF 604 Certification Process
The certification process known as HAF 604 was designed to improve supervision and control over imported safety components and equipment used in nuclear facilities. Obtaining a HAF 604 certification involves multiple steps, each requiring detailed technical and procedural documentation. The process typically includes:
1
Pre-assessment
Confirming product within the scope of “HAF 604”.
2
Application
Filing a formal application with the National Nuclear Safety Administration.
3
Design Appraisal (if applicable)
At accredited laboratories or review of test samples.
4
On-site Inspection
Of manufacturing site, QMS, and testing capabilities.
5
Issuance of License
The HAF 604 certificate is granted following a successful audit and final review.
6
Regular Renewals
A similarly complex renewal process is required every 5 years, with surveillance inspections conducted in between.
1
2
Application & Evaluation
Applicants must provide diligently prepared technical documentation covering the nuclear safety equipment and components. Interest must be shown by at least two Chinese end users. The certification process begins with a regulatory review of these supporting documents.

4
Examination & Testing
Product testing may be required to verify compliance with HAF 604 standards. Specific test samples and sensor-based measurements may be involved. Documentation is reviewed alongside testing to confirm regulatory compliance and product suitability for use in nuclear facilities.
5
Issuance & Validity
The process of obtaining HAF 604 Certification generally takes 10 to 16 months. Once issued, the certificate remains valid for 5 years and is essential for the installation of imported civilian nuclear equipment in nuclear power projects.
6
Follow-Up & Renewal
Renewal every five years requires:
Renewal is complex and demands thorough preparation to ensure continuous certification.
Certificate Maintenance
HAF 604 certificates are subject to mid-term audits and must be updated if:
Non-compliance may result in suspension or cancellation.
Marking & Traceability
Unlike the CCC mark, HAF 604 does not require a specific logo or label. However, strict documentation and traceability of materials, processes, and final inspection results are mandatory. Records must be retained and available for audit by Chinese regulators or nuclear license holders.
