Is ammonium chloride a sublime substance?

Ammonium chloride is a solid formed when two gasses (NH3(g) and HCl(g) ) are put together. (--> NH4Cl(s) )

It may be called 'chemical sublimation', though literally speaking this is a 'contradictio in terminis'.

This looks like a solid cloudy smoke coming out of gas, very much the same as the pure physical sublimation of iodine gas to iodine crystals or the formation of hoar-frost (ice from humid freezing air)
