How much tariff if buying $10k from Japan?

Hi @faustuss It is actually just a few wires rerouted to convert to US AC 115v and Japanese seller confirmed that they will get that done prior to shipping it out to me. As for their credential, I'm pretty confident dealing with them. It'll be my very first over sea transaction but it's not going to be their first. It's what they do and they have 100% and high feedbacks.  My concern on this thread  is tariff- so spanking new to me.

No personal experience with Japan, but for several other puchases (from Singapore, England and Poland), the approach and experience varied quite a bit. The dollar amount for the tariff from Poland was added on as an import or duty cost by FedEx. I was unable to pay online, and then unable to pay by phone (it came to $99) which was actually less than it should have been according to the published tariffs). I emailed the seller to see if he knew anything (like, had he paid the cost?) and they had no clue. A new bill came to me the next month for $89 (no idea why it dropped) and I was able to pay this one to FedEx online.

For my purchases from Singapore, one item was already in the United States in a LA warehouse so it dodged the tariff apparently. The seller promises (on their website) to pay all shipping related costs and ate the tariff on the second purchase. Another Singapore seller finally raised the online prices (explicitly because of tariffs), but still promised to pay all shipping related fees. Finally, a seller to me (not stereo stuff) in the UK, shipped me some goods and had no clue what the tariff related charge would be - it is waiting for me to go to the post office to pick it up tomorrow and I guess I will find out that charge then!  The suspension of de minimis exemptions has really hurt the sales of many international companies (the purchase from the UK was less than $800).

The upshot is that every company is dealing with it differently; the information is changing every day as courts rule against tariffs, then stay the rulings, etc; and no one can keep up. A company in Japan can scarcely be expected to be on top of a constantly changing rule from the US. For your substantial purchase, I would of course first and foremost ask the seller what they are going to do and what their experience has been. But if the overall cost is lower than buying it currently here, then it is still worth it and hopefully your Christmass will start early! Enjoy.

Well as the old saying goes it’s as clear as mud. A few months ago I sent a DAC from here to Switzerland and back. The word repair was in the description when sent away but not for return. No tarriff was charged on the high value item. 

@fpomposo CA tax is 7.25’% (Some locations do also charge city tax making it 10% plus.) Low and middle tax brackets in CA pay leas State Tax than many other states.

@nasaman Hope it’s a tube Amp.
