no that is incorrect!
as i mention above. it goes on the value of the item, and does not inc any shipping fees or other buyer fees you pay. Also just because it is market over $1000 doesnt mean he will be hit with duty and GST....
Its a fact that not every time you will get STOP, so if the value is over $1000, you run the luck of not getting picked up but you also have a chance of having to pay tax.
ps. it is being sent by EMS AIR, just check and the price for 18kg is 22800yen (which works out to be about $250) and 9550yen for sea
ohh and i would be interested to know if you got stop or not let us know
ohhh and if it gets stop, except delays for when you will see it
