That helps - let me make sure we're on the same page (I think so).
Your question is what happens if an individual purchases a thing for his own end use directly from offshore with no middleman - say an Internet purchase from Hong Kong of A DVD player for example?
It was not a question, it was a hypothetical situation on what the Sale Tax police will consider suspecious and target an individual for. If they recieve lots of packages from foreign countries, it is highly likely that they are trying to avoid paying sales tax and would raise red flags to tax auditors.
