Its very simple.

It's admirable to to carry on commerce without worrying about
national boundaries, and I can only wish you continued good luck.

However, one's luck in dealing with agencies of foreign governments,
and sometimes one's own government, is outside one's own control and
can change in expensive and troublesome ways at times.

Mostly I, too, have had good experiences with overseas shipments but the
occasional mishaps can really put a damper on things. So I think it's
more accurate to say that it's simple until and unless it happens to
become quite complicated.
