Shenzhen Zhongnuo Testing Technology Co., Ltd. specializes in consulting services for explosion-proof certification and coal safety certification.
Do we need a Coal Safety Certificate if we already have an explosion-proof certification for the product?
The explosion-proof certificate and coal safety certificate are applicable to different locations.
The explosion-proof certificate generally refers 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-mining explosive gas and dust environments, a防爆 certification is sufficient.
If used in underground coal mines, a coal safety certificate is mandatory; the two certificates are mutually not applicable.

Coal 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 an effective 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 guarantee mechanism for safety production research and development should be established.
Therefore, 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.

Can OEM models apply for the Coal Safety Certification? -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
This year, the Anbang Standard Center has gradually expanded the scope of applicant companies, including OEM production mode enterprises in the Anbang 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 no actual implementation as of now. The potential issues that may arise during actual implementation remain unknown.
For your convenience in filing, please familiarize yourself with the following requirements prior to product application:
Please first select the production address for the declared product. If there is no production address for the declared product in the production address database, the applicant should choose "Add New Production Address" and then complete the production address information as required.
2. When the declared product is self-produced, the applicant's legal business license scope should include the declared product. When the application product is produced under the OEM model, the OEM production factory should be a legal entity, and its legal business license scope 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 pay attention to the validity period of the OEM entrustment 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 period.
