Do all the brands on this platform have SCPN registration?

We are a distributor that is still in the early stages of our business, so we are not very familiar with these processes yet. Therefore, if we decide to source Korean brands, we would prefer to work with brands that already have SCPN registration. If you know of any brands that already have SCPN registration, could you recommend some to us? We previously tried to collaborate with a Korean brand, but the deal could not be finalized because the brand had not obtained the necessary registration yet.
