for many years tea from Ceylon and India were the only available in Poland, so people are quite used to those countries of origin, although now we also have lots of Chinese tea.
A non-professional opinion - the name Sri Lanka never made a career in Poland, for commercial reasons I think it's better to use the name Ceylon (or actually Cejlon in Polish spelling) :)
(we simply don't accept too quick those new country names like Sri Lanka, Myanmar or Burkina Faso, because you don't hear much of those countries, so once people get used to the old name like Cejlon, Birma, Górna Wolta, they don't recognize the new name for a long time after it's been introduced)
