Here you will find various correspondence tables which I have manually constructed in .dta format. These are tables that connect the traditional classification system for goods, which are used in the empirical trade literature (i.e. Nunn 2007; Levchenko 2007; or Chor 2010), with other systems where services are included -- mainly EBOPS. Please quote if you find them useful. Thanks!
