Can the OEM model apply for the Coal Safety Certification? -- Shenzhen ZhongNuo Inspection Technology Co., Ltd.
This year, the Anbang Standard Center has gradually expanded the scope of applicant companies, including OEM production model 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 currently no actual implementation. The potential issues that may arise during actual implementation remain unknown.
Please familiarize yourself with the following requirements prior to product application for your convenience.
Please first select the production location for the declared product. If the production location database does not contain the production location for the declared product, the applicant should choose "Add New Production Location" and then complete the production location information as required.
2. When the declared product is self-produced, the business scope of the applicant's legal person's business license should include the declared product; when the application product is in an OEM production model, the OEM production factory should be a legal entity, and its business scope of the legal person's business license must include the declared product.
3. When the production address is leased, the applicant should note the validity period of the lease agreement. If the declaration date is less than five years from the termination date of the lease agreement, the validity period of the safety label will be affected by the lease agreement.
4. For OEM-produced goods, applicants should be aware of the expiration date of the OEM agency agreement. If the declaration time is less than five years from the termination date of the OEM contract, the validity of the safety mark will be affected by the contract's duration.

Do I need a Coal Safety Certificate if the product already has an explosion-proof certificate?
The explosion-proof certificate and coal safety certificate are applicable to different locations.
Explosion-proof certificates generally refer to facilities used for various explosive gases and dusts, excluding underground coal mines.
Coal Mine 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-coal mining explosive gas and dust areas, a防爆certification is sufficient.
If mining underground coal is required, a coal safety certificate is mandatory; the two are mutually not applicable.
