Given that income tax exemption is longer for "free zone" vs. "promotion zone", how could an investor be registered as a Free Zone investor?

An investor needs to export at least 75% of the production in value to be registered as a Free Zone investor, who is eligible to enjoy seven-year corporate tax holidays. The companies such as logistics that support export-oriented manufactures can also be free zone companies. Domestic oriented manufacturing companies are regarded promotion zone companies and they are eligible to enjoy five-year tax holidays.
