What's the payment method? Make sure to tell him that all checks must clear before you ship, and that he is responsible for all import duties into his country. He will probably want to pay through Bidpay, which is OK because a lot of international buyers pay through Bidpay legitamately, just make sure it clears first.
There's nothing inherently wrong with shipping to another country; just make sure you have your wits about you and make sure payments clear before shipping.
