A few months ago I had seeds sent to me and Customs confiscated the package. I went to their office and they said I'd need to get an import license, which I'm not going to do, so they said they would destroy them.
I did not send them stealth.
A year ago I did have some seeds sent in stealth packaging and they got through.
I'm afraid to order again, though, because I don't want to risk my marriage visa with some sort of violation.
