Simple answer, no you cannot.
You cannot import a resource that you already own. (I would like to do this but we can't)
This in mind, because you cannot import a resource you do not have you cannot export the same resource.
The only exception to this is you do not own say, rubber and you import it and then export it to another civ. You will not own the rubber then, you'll just be the middleman with no rubber resource.
