Marco, I found the same situation as what David mentions -- when we were doing a high profile job that was going to be inspected by a certain someone from Las Cruces, all the wire available from local suppliers was only physically marked as THHN / THWN, but when we dug a little deeper and found the actual spec sheets from the manufacturer we were able to determine that the wire actually was rated as THWN-2 (plus a whole alphabet soup worth of additional listings), although it wasn't marked as such. Have the vendor pull up the spec sheet on the wire brands they typically carry, and keep a couple copies in your "for the inspector" file.
