Can ODM/OEM companies apply for explosion-proof certification and explosion-proof 3C certification? What are the requirements?
Many clients are asking whether their products are OEM-manufactured, ODM-branded, or purchased.
Can we apply for an explosion-proof certificate or the explosion-proof 3C certification?
Here, ChinaNuo 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 the product's design drawings and samples.
No requirements for a production factory. Therefore, whether it's an OEM, ODM, or a product purchased directly, it's all acceptable.
Be able to provide the drawings and samples required for certification, all of which can apply for the explosion-proof qualification certificate.
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, in addition to the explosion-proof qualification certificate, there is a requirement for factory audit and an annual supervision and evaluation.
Therefore, the applicant must have their own manufacturing factory/OEM/ODM factory.
The application process is also more complex and costly, with a longer duration, compared to applying for a explosion-proof certification.
ZheNuo Inspection has been deeply involved in the explosion-proof field for many years, well-versed in the requirements of the GB/T 3836 series standards.
Extensive experience in the design and modification guidance for explosion-proof products.

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 Anbang Standards Center. The validity of the certificates is 5 years, and they are subject to annual supervision and assessment.
Both coal safety certification and mine safety certification applications require two parts: product testing and factory inspection.
The applicant must possess design and development capabilities, and provide complete product design drawings.
And a requirement for an in-house production facility. Some products can also apply for coal safety and mine safety certifications through the OEM process.
If distributors or end-users do not meet these requirements, they are not eligible to apply for the Coal Safety and Mine Safety Certification.
Shenzhen Zhongnuo Testing, as a coal safety and mine safety certification body, is well-versed in the standards and requirements.
A team of engineers and factory audit service professionals.
We offer services including online application, product design and modification, technical drawing revision, and factory audit.

Can coal safety certification be converted to an explosion-proof 3C certification? - Answer from Shenzhen ZhongNuo Testing Technology Co., Ltd.
As per the announcement, as of October 1, 2020, certain explosion-proof electrical equipment has been added to the mandatory product certification catalog.
It 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 process.
Coal Safety Certification is the abbreviation for Mine Safety Certification, which is a mandatory certification implemented by the Safety Standardization Center for all types of products and equipment used underground in coal mines.
The certification method combines "type testing" with "factory audit."
Currently, mandatory product certification bodies and coal safety certification bodies are under different departments.
There is no mutual recognition between them. The Coal Safety Certification and the 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.
