Contract and competition law apply uniformly, but stamp duty on a distribution agreement is a state matter.
Maharashtra charges duty under the Maharashtra Stamp Act, 1958, which carries its own schedule rather than the central one, with distribution agreements usually falling under the agreement entry in Article 5.

Karnataka applies the Karnataka Stamp Act, 1957, with e-stamp certificates widely available in Bengaluru. The Karnataka High Court has no original civil side, so disputes are filed before the commercial courts in Bengaluru, with appeals to the High Court's commercial appellate division. An agreement executed in Karnataka and later received in another state may attract differential duty there.
Delhi follows the Indian Stamp Act, 1899 as amended for the National Capital Territory, with e-stamping as the standard route. The Delhi High Court has original jurisdiction above its pecuniary threshold and a busy arbitration docket. New Delhi is therefore a common seat when a foreign supplier is involved, with interim measures available under Section 9 of the Arbitration and Conciliation Act.
Tamil Nadu applies the Indian Stamp Act, 1899 with state amendments. The Madras High Court hears commercial disputes arising in Chennai on its original side.
