Shenzhen Zhongnuo Testing Technology Co., Ltd. specializes in consulting services for explosion-proof certification and coal safety certification.
We now have the explosion-proof 3C certification, how can we convert it to the Coal Mine Safety or 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 are part of different certification systems and are relatively contradictory. 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.

What are the requirements for obtaining coal safety certification and mine safety certification?
Coal Mine Safety Certification and Mine Safety Certification are mandatory certifications for mining products and equipment.
Coal safety certification is for equipment used in coal mines, and mine safety certification is for non-coal mine equipment. Both are applied for, reviewed, and certified by the Safety Standard Center.
Certificates are valid for 5 years and must undergo annual supervision and review.
To apply for coal safety and mine safety certifications, both product testing and factory inspections are required. Applicants must possess design and development capabilities, provide complete product design drawings, and have their own manufacturing facility.
Some products can also apply for coal safety and mine safety certifications through OEM.
If distributors or end-users do not meet these requirements, they are not eligible to apply for the Coal Mine Safety and Coal Safety Certification.

Currently, the frequent occurrence of coal safety certification is under the Safety Standardization Center. Under the Safety Standardization Center, there are various local Testing institutions, each responsible for the Testing tasks of different product fields. Generally, when a company applies for coal safety certification, they cannot directly find a laboratory to conduct Testing; instead, they must go through the Safety Standardization Center's designated Testing and certification laboratories. In fact, the domestic coal safety certification system is still quite strict. It combines type testing with factory production system review to ensure that the applicant company has the capability to ensure product production and quality. Even after obtaining the coal safety certification, the company must undergo an annual supervision and evaluation by the Safety Standardization Center.

Coal Mine Safety Sign Certification is a mandatory certification implemented by the Coal Mine Safety Sign Office for items used underground. All products listed in the Coal Mine Product Safety Certification Catalog must obtain a certification certificate.
Products with Coal Safety/Mineral Safety certification may affix the MA/KA mark. Individuals and entities are prohibited from selling, purchasing, or using mineral products included in the safety mark management catalog without obtaining the safety mark.
To obtain a safety mark from the product manufacturing enterprise, several steps are required, including filling out an application form, preliminary review and qualification registration, assessment, and issuance of the certificate.
