Yes, you are right. EU adopts new HS revision as soon as it is made
available. That is, from 1996-2001 HS96, 2002-2006 HS2002, and from
2007 onward, HS2007. But you no not need to worry about it as in
TRAINS, all HS revisions are combined into what is called "HS
Combined". If you choose a 6-digit code for 2005 which is only
introduced in 2007, you simply get no data.
