We study the Kantorovich-Rubinstein transhipment problem when the difference between the source and the target is not anymore a balanced measure but belongs to a suitable subspace X(Ω)\mathbf{X}(\Omega) of first order distribution. A particular subclass X0♯(Ω)\mathbf{X}_0^\sharp(\Omega) of such distributions will be considered which includes the infinite sums of dipoles ∑k(δpk−δnk)\sum_k(\delta_{p_k}-\delta_{n_k}) studied recently by A. C. Ponce ["On the distributions of the form ∑i(δpi−δni)\sum_i (\delta_{p_i}-\delta_{n_i})", C. R. Math. Acad. Sci. Paris 336 (2003) 571–576; and "On the distributions of the form ∑i(δpi−δni)\sum_i (\delta_{p_i}-\delta_{n_i})", J. Funct. Anal. 210 (2004) 391–435]. In spite of this weakened regularity, it is shown that an optimal transport density still exists among nonnegative finite measures. Some geometric properties of the Banach spaces X(Ω)\mathbf{X}(\Omega) and X0♯(Ω)\mathbf{X}_0^\sharp(\Omega) can be then deduced.
