Shenzhen ZhongNuo Testing Technology Co., Ltd. specializes in consulting services for explosion-proof certification and coal mine safety certification.
What is the Coal Safety Certification?
Coal Mine Mark Certification (abbreviated as MA, KA Certification) is a mandatory certification implemented by the Coal Mine Safety Mark Office for products used underground in coal mines.
Products listed in the safety certification directory for mining products must obtain certification certificates. Individuals and organizations are prohibited from selling, purchasing, or using mining products included in the safety sign management directory but not yet possessing a safety sign.
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, evaluation, and issuance of the certificate.

Coal Safety/Mine Safety Certification Differences -- Shenzhen ZhongNuo Inspection Technology Co., Ltd.
1. Distinctions in Definitions. Coal Safety Certification, abbreviated as MA Certification, is self-explanatory, used for underground coal mines. Mine Safety Certification, or KA Certification, is for non-coal mines, including other metallic or non-metallic mines; this is the fundamental difference.
2. Testing varies. During the type testing phase, their testing methods also differ. In terms of performance, both coal safety certified products and mine safety certified products undergo testing based on the same industry standards. However, when it comes to safety performance, coal safety certification requires explosion-proof testing according to the explosion-proof standard GB/T 3836, while mine safety certification equipment must undergo testing based on industry standards. Coal safety certification is more inclined towards preventing explosions, while mine safety certification focuses more on safety performance. This is the difference in their type testing.

Coal Mine Safety Sign Certification is a mandatory certification implemented by the Coal Mine Safety Sign Office for items used underground in mines. All products listed in the Coal Mine Product Safety Certification Catalog must obtain a certification certificate.
Products with coal safety/mining safety certification can be marked with MA/KA labels. Individuals and organizations are prohibited from selling, purchasing, or using mining products included in the safety label management directory but without a safety label.
To obtain a safety symbol from the product manufacturing company, several steps are required, including filling out an application form, preliminary review and qualification registration, evaluation, and issuance of the certificate.

Can OEM models apply for the Coal Safety Certification? -- Shenzhen ZhongNuo Inspection Technology Co., Ltd.
This year, the Anbao Center has gradually expanded the scope of applicant enterprises, including OEM production mode companies in the Anbao application range. This means that companies previously operating under the OEM production model can now apply for the Coal Safety Certification themselves. However, there is currently no actual implementation. The potential issues in actual implementation remain unknown.
For your convenience in declaration, please familiarize yourself with the following requirements prior to product application:
Please first select the production address for the declared product. If the production address library does not contain the production address for the declared product, the applicant should choose "Add New Production Address" and then complete the production address information as required.
2. When the declared product is self-manufactured, the scope of business in the applicant's legal person business license should include the declared product; when the application product is produced under the OEM production model, the OEM production factory should be a legal entity, and the scope of business in its legal person business license must include the declared product.
3. If the production address is leased, the applicant should pay attention to the validity period of the lease agreement. If the declaration time is less than five years from the termination date of the lease agreement, the validity period of the safety mark will be affected by the lease agreement's validity period.
4. For OEM-manufactured products, applicants should note the validity period of the OEM agency agreement. If the declaration time is less than five years from the termination date of the OEM contract, the validity period of the safety mark will be affected by the contract's validity.
