In the title compound, C10H8Cl2O4, the two Cl atoms and one of the methoxycarbonyl groups are almost coplanar [maximum derivation = 0.035 (2) Å] with the benzene plane, and the other methoxycarbonyl group exhibits an almost orthogonal disposition relative to the benzene plane, with a dihedral angle of 84.82 (3)° between the planes. In the crystal, the molecules are connected into a chain propagating along the  direction through nonclassical C—H⋯O hydrogen bonds.
