Registration Requirement if i am storing my goods in another state

May I know whether Registration is Required if i am storing my goods in another state. I have registration in Karnataka state and i want to store my goods in Kerala and sale those in Kerala. I have no GST registration in Kerala.
Can I store goods in cold storage in Kerala without having any registrations ? And I can sell the goods by issuing IGST Invoice to Kerala ?

Or I need to take a Normal Registration or CTP Registration in Kerala

please guide me on the issue
