Yes, I'd definitely check with your customs officials as red-tape changes rapidly, and it would be better to know before you get a nice bill for duty!! (Australia: under $1000 seems to be happily ignored. I ordered some parts for my classic car a few months back, and the US supplier split the order into 2 shipment - to keep it under $1000. Postage for the two was still less than any duty I may have been slugged with, so was happy to receive the shipments separately. )
