The US has a Small Seed Lot import permit through APHIS. The permit is free, lasts for 3 years and small lots of seed do not requite CITES. (Lots under 50 seeds.)

I did check this out before posting, as I am aware of the plant health import laws. This is the reason I searched out a company that sold the Teucrium seeds in lots of 25 or less, rather than the actual living plant. The link was posted because Leslieray mentioned an interest.
