We present our results on terahertz photoconductivity studied in epitaxial Hg1-xCdxTe films with the inverted energy spectrum (x<~0.16) in the nonlocal (Hbar type) geometry. We show that the terahertz photoresponse demonstrates nonlocality and chirality in magnetic field. We discuss the results in terms of a qualitative model that takes into account coexistence of the bulk transport and boundary conductive channels.
