Now that we have the explosion-proof 3C certification, how can we convert it to a coal mine safety or mineral mine safety certification? -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
In China, explosion-proof 3C certification/examination certificate and coal safety/mining safety certification belong to different management systems, and the product usage locations are also different. The two certificates belong to different certification systems and are relatively opposed. Regardless of which certificate is held, the other certificate must be re-applied for according to the new product application process. Similarly, if a coal safety/mining safety certification is obtained, applying for an explosion-proof examination certificate or explosion-proof 3C certification also requires re-applying according to the new application process.

Coal Mine Safety Sign Certification is a mandatory certification implemented by the Coal Mine Safety Sign Office for items used underground in mines. Any product listed in the Coal Mine Product Safety Certification Catalog must obtain a certification certificate.
Products with Coal Safety/Mine Safety certification can affix the MA/KA mark. Individuals and organizations are prohibited from selling, purchasing, or using mining products included in the safety mark management catalog that have not obtained a safety mark.
The manufacturer of the product must go through several steps to apply for a safety mark, including filling out an application form, preliminary review and qualification registration, assessment, and issuance of the certificate.

What are the requirements for applying for the Coal Safety/Mine Safety Mark? -- Shenzhen ZhongNuo Inspection & Testing Technology Co., Ltd.
Meets safety production requirements for coal mines, in compliance with current standards, industry safety standards, and the "Coal Mine Safety Regulations."
(2) Proper and complete technical documents are available.
(3) New products produced with new materials, technologies, and processes should have evaluation opinions from relevant departments.
(4) Other relevant conditions.

Does a product with an explosion-proof certificate still need a coal safety certificate?
The explosion-proof certificate and coal safety certificate are applicable to different locations.
Explosion-proof certificates generally refer to facilities used in places where explosive gases and dusts are present, excluding underground coal mines.
Coal Safety Certificate refers to the safety certification mark for equipment and products used underground in coal mines.
So, whether to apply for an explosion-proof certificate or a coal safety certificate depends on where the product is used.
If used only in non-coal mine explosive gas and dust areas, a explosion-proof certificate is sufficient.
If coal mine operations are involved, a coal safety certificate is mandatory; the two certificates are mutually incompatible.
