We study optimal transportation problems with constraints on densities of transport plans. We obtain a sharp condition for the uniqueness of an optimal solution to the Kantorovich problem with density constraints, namely that the Borel measurable cost function h(x, y) satisfies the following non-degeneracy condition: h(x, y) can not be expressed as a sum of functions u(x) + v(y) on a set of positive measure.
