As far as I know, Hershey's. I loved running loads for them. Nice people. Funny thing that I remember was that they didn't have not one candy bar in the break room vending machines. the best part of delivering those loads...opening the trailer doors. Then reopening them! The aroma would be too much for you! Lol
Hardly any brand of chocolate is sold worldwide. Even international companies like Cadbury, Hershey or Ferrero make different types of chocolate for the different countries, also because people in different parts of the world have other preferences for the taste.
