Mine was released through customs with no issue, but the link in the text I got did say that I owe $62.82 for import duty/tax at pickup.  I was pleased with that amount, was afraid it was going to be several hundred for a $15K order of four S11s with power supplies.   Earlier this year I sent one A4 to Canada and the buyer had to pay more than that, so I am thankful this is inexpensive.
