> If you ordered delivery by say FedEx and they paid the duty and passed it on to you, you should have a reasonable case to get it refunded from FedEx when they get the money back. Ideally they handle it automatically since they have all the necessary details.

I didn't have to deal with it, but from other comments, most of the international shippers also charged a hefty fee to broker the tarrifs. Expect not to get that refunded.
