Steve,
The best way is to get someone in the states that has a seed permit and ship them to their place (of course I would volunteer for that, haha). Depending on what seeds you are sending there are different methods.
Anyway, I have a friend going over there in a few weeks with a permit to bring live plants and scions back here, although I have to quarantine them for 2 years at my place. But the seeds you don't have to quarantine. I would sure like to get some of the jujubes barerooted back here.
Good luck, Mark in San Diego
