A question for those of the American persuasion

In the children's library I'm currently working in, we have small exhibits of various stuff - currently a small part of a collection of Kinder Egg things. Yesterday the collectors themselves were present - to answer questions and hand out chocolate - and they mentioned something very strange. Tell me, can it really be true that there are no Kinder Eggs in the US? That they are, in fact, illegal over there?
