This should be for products in the explosion-proof 3C catalog, such as motors, fans, walkie talkies, etc., all of which belong to the explosion-proof 3C catalog,
Those who have previously obtained an explosion-proof certificate need to convert to an explosion-proof 3C certification certificate.
The application for explosion-proof 3C certification adopts the "product testing factory review" method, which requires the applicant to have a production factory or OEM/ODM factory.
Explosion proof products outside the 3C certification catalog only need to obtain an explosion-proof certificate.
