How much tariff if buying $10k from Japan?

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. 

@wsrrsw I’m in LA , LA county is 9.75%, some areas are even higher at 10.25%.. I’m a reseller and I collect and pay monthly sales tax payments for my business on top of all the stuff I buy. The reason I say it's a ripoff is because of how insanely bad, wasteful, mismanaged and embarrassing our state is ran, highest cost of everything, highest taxes, and highest in homeless camps and lots of other problems...

Newsome just spent $450 million to "update" the 911 system  then they announced they scrapped the whole program and the money is gone, and that is just the tip of the iceberg of insane fraud and waste, secret billions to upgrade the capital building all with secret contracts, the corruption and incomptence never ends in California 

@fpomposo respectfully, you have no idea how CA is run if you say nonsense like this. Be specific about where the corruption and incompetence is otherwise it's just baseless accusations.
