what you say is possible, although it would make goods a little uncompetitive. In any case the problem is not one of taxation. The EU has granted the TC chambe rof commerce the full authority to certify goods and services produced in the occupied areas. These goods can then be moved via authoristed ports. The RoC has offere preferential port charges for TC goods. But the point is not to move goods and overcome the so called isolation.
The goal is to have ports and airports certified for international traffic and thus move a step closer to recognition without giving anything in return.
It is obviouis that citrus from the Morphou area can be moved more cheaply via Limassol than Famagusta. The insistence on Famagusta is for obvious reasons.
