Do I need to do explosion-proof design before applying for explosion-proof certification for a product?

That's for sure.

To obtain explosion-proof certification for a product, it is necessary to pass the relevant testing items of explosion-proof standards and obtain the explosion-proof qualification certificate.

To ensure that the product can pass the explosion-proof standard related testing projects, it is necessary to design the product according to the testing requirements, that is, to do explosion-proof design.

For example, explosion-proof design should refer to GB/T3836.1 and GB/T3836.2, intrinsic safety design should refer to GB/T3836.1 and GB/T3836.4, and positive pressure design should refer to GB/T3836.1 and GB/T3836.5

The national explosion-proof standard GB/T 3836 series has clear design requirements for various explosion-proof types, different explosion-proof areas, and different explosive environments.
