I am trying to finish off my fireplace surround. I am thinking I need a non-combustible material that would withstand repeated temperatures around 400F.I purchased some Hardiebacker, but - it seems it is only rated to around 210F. Anyone familiar with National code and what a building inspector would accept as a suitable non-combustible cement type board.

You need to read the msds for the product you are going to use. It should be rated as noncombustible.
I am looking at a Hardiebacker, and Durock product. They both state that they have ASTM E84 & ASTM E136 fire ratings. ASTM E136 uses 1300 F burner to test the product. Well above what my fireplace brick front would ever reach, but the - each product states in their "limitations" not to be used in areas exceeding 210 - 220F. This I do not understand. Do you have insight to this.
Looking at the MSDS for Hardibacker, it appears to be a "safety" sheet. Melt point, Flammability , and Flash Point - all state "Not Applicable". I do not see a fire rating or standard listed.
