According to the official source of the States, since March 11, custom tax allowance for individual importation had increased from $200 to $800. When purchase item from overseas, importation tax is one of taxes due. Therefore this is a great news for the US residents.
I believe that purchasing from overseas will expand more and more. Japan had recently agreed TPP provision and will be able to free trade with over 10 countries in the world.
Today’s news is for the States, but I believe that similar exercise will be done in other countries too.
