other than the shipping costs being higher
you don't need to worry about taxes or other stuff. the guy getting it will have to claim it's worth and he will pay what ever they decide.
i recently sold some fairing lowers to a guy in Denmark. he asked that i wrap them in Christmas paper and write a note stating "Don't open 'till Christmas" and put it in the box. the import people still screwed him and made him open the box, unwrap the "present" and charged him a % of what they felt the part was worth. can you imagine the monkeys at the US Post Office trying to determine the worth of some old Duc parts?
so your buyer will have to be aware that he might get zinged when he picks the stuff up and that the initial shipping will be higher than what you stated in your auction. you won't be out anything if he gets caught up in red tape because of his countries messed up postal laws. he should be aware of these laws since he lives there.
