A higher-twist nuclear enhancement of R=\mathrm\ensuremathσL/\mathrm\ensuremathσT whose magnitude is within the error bars of recent experiment is shown to lead to a monotonic decrease in the ratio of nuclear versus nucleon cross sections at small Bjorken x for increasing Q2. This effect at small X, comparable in magnitude to those reported for nuclear shadowing, is driven mainly by kinematic factors and essentially vanishes for x>0.1. Its unusual Q2 dependence rather complicates the unraveling from present data in the shadowing region the corresponding dependence in Q2 of the nuclear structure functions, F2A(x,Q2).
