The DK2 had a logo on the headset and the camera. So I think there is definitely one
on the Rift, too. But I understand your question and concerns. The German costumes
returned once a collector’s edition Nintendo 3DS to Japan, because of the missing CE
logo. The customs told me it’s a potential danger. So I bought it 5 month later
used in Akihabara... and brought it back by plane (used in japan is always
perfect ;-)). If you are in Europe, the Rift is (I think) shipped via England.
So it’s already in Europe and Customs are already payed. (That’s why the
delivery is so expensive. DK1, DK2 where delivered that way)
