Can the OEM model apply for the Coal Safety Certification? -- Shenzhen ZhongNuo Inspection & Testing Technology Co., Ltd.
This year, the Anbang Standard Center has gradually expanded the scope of application enterprises, including OEM production model companies in the Anbang application range. This means that companies previously adopting the OEM production model can now apply for the Coal Safety Certification themselves. However, there is currently no actual implementation. What kinds of issues may arise during actual implementation remains a mystery.
Please familiarize yourself with the following requirements prior to applying for the product for your convenience in declaration.
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. If the declared product is self-produced, the applicant's legal person business license scope should include the declared product; if the application product is produced under the OEM model, the OEM production factory should be a legal entity, and its legal person 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 validity period of the lease agreement.
4. For products manufactured under the OEM model, 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.

Coal Safety/Mine Safety Certification Differences
1. Distinctions in Definitions. Coal Mine Safety Certification, abbreviated as MA Certification, as the name implies, is used in underground coal mines. Mine Safety Certification, or KA Certification, refers to other metal or non-metal mines that are not coal mines, marking the fundamental difference.
2. Testing varies. During the type testing phase, their testing methods are also different. In terms of performance, 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's safety performance must be tested according to relevant industry standards. Coal safety certification is more inclined to prevent explosions, while mine safety certification is more focused on product safety performance, which is the distinction between their type testing.

What explosion-proof certifications are required for explosion-proof products? What are the institutions for applying for explosion-proof certifications?
Currently, the certification models for explosion-proof products entering the Chinese market are mainly three.
1. Obtain explosion-proof certification for equipment used in environments with explosive gases and combustible dust in non-coal mines. Simply conduct product testing; upon passing, the certificate is issued.
2. Conduct explosion-proof 3C certification; for products listed in the explosion-proof 3C directory, product testing and factory inspections are required.
3. Coal Mine Safety Certification, applicable to explosion-proof equipment used underground in coal mines, involving product testing and factory audit certification process.
