Pickfords use a local company in Turkey as they dont have an office here. When you get your estimate from them check the small print. Generally THC, SIT and local taxes are not included in the estimate. THC (terminal handling charge) is normally a straight forward fee but SIT (storage in transit) would not be included as thats a daily storage rate of your container being in the Turkish port and is charged from the day it arrives to the day it physically leaves the port. Also remember that the longer your goods stay in a container at the port as you are trying to get all your paperwork, the shipping line who owns the container charges demurrage for use of their container on a daily basis.
Just be prepared for costs like this that would not be included in your estimate.
