Do you need a factory audit to apply for the Coal Safety/Mineral Safety Mark? -- Shenzhen ZhongNuo Inspection & Testing Technology Co., Ltd.
Necessary. Unlike applying for an explosion-proof certificate, there are strict regulations concerning the control of mining signs.
Application for Coal Mine Safety and Mine Safety Certification requires a factory audit of the applicant company.

Do the Coal Safety/Mineral Safety signs require annual inspections? -- Shenzhen ZhongNuo Inspection & Testing Technology Co., Ltd.
The Mark Management Authority conducts annual supervision and management for enterprises that have obtained the Coal Safety/Mineral Safety Mark.
Generally, companies are notified in advance of the annual supervisory review to prepare for the assessment, which is relatively stringent.

Coal Mine Safety Certification is the abbreviation for Coal Mine Safety Certification.
In 2007, the Economic and Trade Commission and the Coal Mine Safety Supervision Bureau issued documents such as the "Temporary Measures for the Safety Marking of Coal Mine Products," implementing a safety production certification system for equipment, instruments, and meters used in underground coal mines, effectively preventing substandard products from entering the mines. The safety production marking system is a practical approach. To enhance coal mine safety, there is an increasing emphasis on safety technology development. The funding methods for technological development have been reformed. Due to insufficient safety investment, a financial security mechanism for safety production research and development should be established.
So, all types of equipment and products used in coal mine underground must pass the safety certification system of the Safety Standardization Center and obtain the corresponding coal safety certification.

We now have the explosion-proof 3C certification, how can we transition 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 are used in different locations. The two certificates are part of different certification systems and are mutually exclusive. Regardless of which certificate is held, the other 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.
