That will be up to what your quarantine regulations are. We have a site here with a data base giving the requirements for importing anything into the counrtry. Your quarantine people possibly have something similar. Although, Tindara probably know already since they send them to other countries. But a warning note, I got some seed from Tindara a few years back and they sent soil with them. They SHOULD have known it's illegal to import soil into most countries but did it all the same. I got a letter from our quarantine people saying they were going to destroy the whole package and contents. I rang them and pleaded with them to spare the seeds. The seeds weren't mixed with the soil so wouldn't have been contaminated. I don't know whether it was my tears (very few people can stand seeing a grown man cry, LOL) or my logic that changed their minds. Who cares, I ended up getting the seeds finally.

But not neccessarily, so take a look.
