I do not know about the X, unless it has something to do with whether you are qualified to operate a vehicle with airbrakes or not, but the N stands for tanker endorsement, and the T stands for doubles/triples endorsement. I do not remember what the endorsement letter is for haz-mat, so that could be it as well. Contact your local DMV and ask for a copy of the Commercial Vehicle LIcense Study Guide; they will be listed in there within the first few pages.
