Currently there is a shipping ban to any of the European Union countries because of a bacteria called Xyrella. Most nurseries have stopped overseas shipping completely.
Hand-carrying plants out of the US has never been allowed.
Before the ban, nurseries would require a minimum order amount for overseas shipping - generally around $500. On top of that is the actual cost of shipping plus cost of the phyto fee. (About $75.00)
Any fees incurred overseas for customs, etc. are always the customer's responsibility.
