How much will I now pay in duties to ship a stylus from Japan?

herman, If what you say is true, that shippers have to calculate tariff (duty) based on country of manufacture, not country from which the shipment originated, that seems really awkward

Of course it is true. If not,  companies from countries with high tariffs would first ship to a country with low tariffs and then on to the US, which has already been going on.

@faustuss yes, that is true. I am using a transformer, and I was told that the unit would not be warrantied in the USA. These Japanese stereo units being sold on eBay are for the Japanese market. That is why they are at such a lower price. I was willing to take the chance to save $8000

I imported a SUT in September.  Duty was 15%.  Shipped with UPS and the process and the process was pretty simple.  Bought something else in October that was shipped with DHL.  That was a big pain so I would not use them again if I could avoid it.
