ABSTRACT

If a party fails to pay the price or any other sum that is in arrears, the other party is entitled to interest on it, without prejudice to any claim for damages recoverable under article 74.

Art. 78 CISG states the duty to pay interest on a sum which is due. It is supplemented by Art. 84 CISG, which applies in cases where the contract has been avoided and obligates the seller to pay interest on the purchase price to be refunded.
