i disagree. international sellers are not going to list something new as used just in case a tax is to be paid by the buyer. they have to list something correctly for auction. thus its new or used status is reasonably correctly established. there is a definite blanket approach to make life easy for tax collection.

You obviously dont do much international trade.  Every second buyer wants items either sent as gifts, or fudge the purchase price

to reduce or eliminate their import costs.  And wher would  New/Unused items sit.
