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/Mineral Safety Certification are eligible for the MA/KA label. Individuals and entities are prohibited from selling, purchasing, or using mineral products included in the safety sign management directory without obtaining the safety sign.
The product manufacturer must undergo several steps to obtain a safety mark, including filling out an application form, preliminary review and qualification registration, evaluation, and certification issuance.

Basic Process and Agencies for Coal Safety Certification
Coal safety certification is a mandatory safety certification for equipment and products used in coal mine underground. It follows the "Product Testing + Factory Audit" approach, which involves both testing the applied products and conducting on-site audits and annual supervisory reviews of the production factories for the applied products, which is commonly referred to as factory inspection.
The product testing aspect requires that the products meet the Coal Safety standards, such as electrical products needing to consider the explosion-proof requirements in the coal mine gas environment, as well as meeting the product performance requirements.
Factory audits are primarily based on the ISO9001 production quality system, further combined with the requirements of the Mine Product Safety Mark Implementation Rules for factory evaluation. The Safety Mark Center is the coal safety certification issuing and inquiry institution.

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 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.
