Can ODM/OEM companies apply for explosion-proof certification and explosion-proof 3C certification? What are the requirements?
Many customers are asking whether their products are OEM-manufactured, ODM-branded, or purchased.
Can we apply for a explosion-proof certificate or explosion-proof 3C certification?
Here, ChinaNo Inspection introduces the requirements and conditions for applying for explosion-proof certification and explosion-proof 3C certification.
If applying for an explosion-proof certification, the company only needs to provide product design drawings and samples.
No requirement for a production factory. Therefore, whether it's OEM, ODM, or products purchased directly, just
Provide the required drawings and samples for certification, and they are eligible for explosion-proof certification.
Of course, the provided drawings and samples must comply with the requirements of the explosion-proof certification standards.
To obtain the Explosion-Proof 3C Certification compared to the Explosion-Proof Certificate, an additional factory audit and an annual supervision and assessment review are required.
Therefore, the applicant must have their own production factory/OEM/ODM factory.
The application process is also more complex than applying for the explosion-proof certification, with higher costs and a longer timeline.

What are the requirements for obtaining coal safety certification and mine safety certification?
Coal Mine Safety Certification and Mine Safety Certification are mandatory certifications for mining products and equipment.
Coal safety certification is for equipment used in coal mines, while mine safety certification is for non-coal mine equipment.
Certificates are all applied for, reviewed, and issued at the ANSI Center. Validity is for 5 years, with annual supervision and evaluation.
To obtain both Coal Safety Certification and Mine Safety Certification, both product testing and factory inspections must be completed.
Applicants must possess design and development capabilities and provide complete product design drawings.
And require an in-house production facility. Some products can also apply for coal safety and mine safety certifications through the OEM process.
If dealers or users do not meet these requirements, they are not eligible to apply for the Coal Safety and Mine Safety Certification.

Can coal safety certification be converted to explosion-proof 3C certification? - Answer from Shenzhen Zhongnuo Testing Technology Co., Ltd.
Pursuant to the announcement, as of October 1, 2020, certain explosion-proof electrical equipment has been transferred to the mandatory product certification catalog.
That is the CCC certification. Products under the explosion-proof 3C certification category obtain the explosion-proof CCC certification by undergoing a "type test + factory audit" certification method.
Coal Mine Safety Certification, abbreviated as CMSC, is a mandatory certification adopted by the Safety Standardization Center for various products and equipment used underground in coal mines.
The certification method is a combination of "type testing" and "factory audit."
Currently, mandatory product certification bodies and coal safety certification bodies are under different departments.
There is no mutual recognition between them. Coal safety certification and explosion-proof 3C certification are independent of each other.
The coal safety certification or the explosion-proof 3C certification cannot be substituted or converted for each other; they must be applied for separately.
