Any problems selling equipment outside of USA?

For private party, after the deal is finalized,the best way to handle the transaction is to have the buyer wire money to your bank before sending the amp.

I live in United Arab Emirates and have bought and sold many things on Audiogon sometimes to/from the US and others to Europe. No problems, the same rules apply. Sometimes sellers worry about customs. You see the customs are the responsibility of the buyer. So the most that you would do in enclose an invoice describing the item and the market price for it. And if you want to help the buyer reduce the cost of customs you should reduce that value.

I sold my speakers (Snell A/IIIi totalling over 300 lbs) to a guy in Italy. I wasn't too keen on the process, but the buyer knew what he was doing and contacted shippers himself. He wired the money to me and the shippers came for the speakers (I had the original boxes) and everything went smooth from there. Letting the buyer arrange the shipping has the advantage that he/she is better equipped to handle the customs problem.

We have done dozens of transactions all over the world...We always follow the same routine no matter where the items are going (overseas); have the buyer do a wire transfer to your account before you ship. We use USPS Global priority on small items and fedex on larger ones...we have never had a problem.

I am glad to see shipping around the world is positive. I reside in Canada and have had no problems. I have found some people a little hesitant at first, but after they find out it is really no different than shipping domestically (other than declaring what you are shipping), it goes well.
I have done about 95% of my transactions outside of Canada. The majority with American customers- has been a pleasure doing business!
