Question one: who is the customer?
Income from a transaction with another free zone person is qualifying, unless it comes from an excluded activity. The free zone customer must be the beneficial recipient of the goods or services, meaning it actually uses or enjoys them rather than passing them straight to a mainland party.
Example: a Sharjah Airport International Free Zone packaging maker sells AED 2 million of cartons to a SAIF Zone food producer that uses them in its own production. That is a transaction with a free zone person that is the beneficial recipient, so it is qualifying.
