Humudepts are the Inceptisols that have an udic moisture regime and an umbric or mollic epipedon.
Andic Humudepts are the Humudepts that have, in one or more horizons with a total thickness of 18 cm or more within 75 cm of the mineral soil surface, a fine-earth fraction with both a bulk density of 1.0 g/cm3 or less, measured at 33 kPa water retention, and Al plus 1/2 Fe percentages (by ammonium oxalate) totaling more than 1.0.
