There is an ongoing discussion over at the Nihonto Message Board that illustrates some of the confusion surrounding international shipping these days:

From personal experience, earlier this year I received a package via UPS. There was no duty payable, but I had to pay about $40 for customs clearance services. The postal services were not making charges on values under $800 per
de minimus. With the postal route currently suspended, these charges become a consideration. As you will see from the NMB thread, there remains a lot of confusion.
