How much tariff if buying $10k from Japan?

AI should know that 👍

Tariffs are assessed based on where the product is manufactured and materials are sourced from, not necessarily the same as the country it's shipping from.

I recently bought a power supply from PD Creative in Poland for approximately $232.  The tariff amount on products from the EU is 15%, which would be $35 rounded off.  I received an email from Fedex for $60.  There was no break down on of the charges on the email, although it is apparently $25 for something.  I called the Fedex help line and asked them to explain the charge; they said they could not explain until a paper invoice was created, which I haven't received.

I had a nice discussion with Fedex employees, who all speak English as a second language which makes the conversation a bit difficult.  They couldn't understand my aggravation in being sent a bill which they couldn't explain.  In any event I am still waiting for an explanation.  Bottom line, I am paying an effective 26% to import the product, not counting having to deal with customs via Fedex.

Thank you @abnerjack and ev1 . Your answer is very helpful.

I entered very specific month (November) and amount ($10k) in hope to get most updated, accurate and helpful responses?…. or maybe someone’s past experience that can help to avoid or reduce tariff?

@abnerjack you spoke with FedEx employees in the US? 

Last year I sent a package to India. It was 2 DVDs and a laptop. The laptop 15 years old, I sent it for the hard drive. 

I declared the value, paid all the fees but in India it was not released by the customs unless the recipient paid another $200. They had no explanation. It was ransom. I have many stories like that shipping to all over the World regularly.

In most developing countries that's how the government works. There is no taxpayer BS. There is no representation. Every agency may very well be a criminal enterprise. But people don't call it that, they just call it business as usual. 

Now Americans get to experience this first hand, Customs are encouraged to make life difficult for buying stuff from abroad.
