Can a domestic NEPSI explosion-proof certification be converted to an international IECEx certification?
Domestic explosion-proof certifications cannot be directly converted to IECEx certifications. This is because the domestic explosion-proof certification standards (GB/T3836) are essentially direct references to the international IECEx explosion-proof certification standards (IEC60079). Therefore, possessing a NEPSI certification does not allow for direct conversion to an IECEx certification.

Can IECEx certification be converted to a domestic explosion-proof certification? -- Shenzhen Zhongnuo Testing Technology Co., Ltd.
Currently, the IECEx certification is driven by standards, which is a voluntary certification.
But the IECEx certification is highly recognized in the international market.
Most IECEx member states directly or indirectly recognize the IECEx certification.
If the product has obtained IECEx certification,
Provide valid Reports (Ex Reports and Factory Quality Assurance Reports (QAR) issued by Ex CBs from other member states in the IECEx system).
Manufacturers from other member states that already hold an IEC Ex certificate only need to undergo a portion of the testing process to apply for access to regional certification pathways.
For instance, China, as an IEC member, still requires the application for a Chinese explosion-proof certification or coal safety certification for explosion-proof products.
This cannot be replaced by IECEx. In summary, if a country is a member of the IEC but also has its own mandatory explosion-proof certification,
Typically, it's mandatory to apply for your own explosion-proof certification, rather than simply using an IECEx explosion-proof certification as a substitute.
Of course, at times, the IECEx Report already obtained (possibly requiring additional test items) can be used.
To convert into a domestic mandatory explosion-proof certification, but it is absolutely necessary to pass the confirmation and review of the application institution.

Explosion-proof electrical products, also known as Ex products, are required to obtain explosion-proof certification before being allowed for use in hazardous explosive areas.
To eliminate unnecessary repetitive inspections and certifications of Ex products across international borders.
Promoting international trade, the guo ji Diangong Hui Explosion-Proof Electrical Products Certification Organization, abbreviated as IECEx certification system, was officially established in 1996.
