No additional charges where applied, I do know that when international Shippers, forwarders, couriers etc give you a quote they do ask for the value of the item/s to be shipped along with all other details. I believe that a big company like parcel force would include all clearance/customs charges in their price as they would handle that being that they provide a door to door service.
Might be different if you were to get it through ebay or something, not too sure.......
