I believe you are allowed to purchase items to value of $800 from outside the USA before you are supposed to incurr any tariffs.
And of course it all depends on how the seller lists price and items on their paperwork.
I have bought numerous vinyl from Europe and a couple of phono cartridges from Japan.
All with zero issues, most expensive was a cartridge at $869, technically some tarrif but I was never asked for any additional funds from anywhere.
