Update 10/20:
K, so very strangely I received an envelope in the mail from FedEx with a record number and details about my shipment. My total charges are listed as $0.00 because they listed the country/territory of manufacture as the U.S.A. and in Box 33 of the Entry Summary the rate is "FREE".
I reckon this must have something to do with how Blue Lug is filling out customs forms? or with how people at Homeland security are reading them? For a Taiwanese made frame, designed by an American company, imported to Japan, then exported to the USA to have no Tariff or Import Duty feels like a comedy of errors. I didn't even pay sales tax!
Don't get me wrong, I'm more than happy to only pay shipping on the frame... but whaaaaa?
