I'm not sure I get the question. Are you talking about exporting dropship items?
I used to export auto parts (used OEM Toyota MR2 Turbo parts to be specific) to Asia, Europe, and the Americas all the time. Like Pete said, people abroad can't get alot of this stuff, so if you've got the product and you're willing to deal with the customs process, you've got a market.
We sourced the parts ourselves, so there really wasn't a supplier, and perhaps I'm missing the point completely. What I do know is this: if you're willing to simplify the process for the end-user, and make acquiring what they want easy (and priced competitively relative to the ease of acquistion), you'll get buyers. They don't care about how many moving parts there are in the process, as long as they get what they're paying for.
In our case, we were lucky to have a product that, outside of Japan, was really only US centric. For people not in Japan or the US, they had a need. Most US/Japanese MR2 parts dealers didn't want to screw with exporting, so we got their customers.
