United Nations Convention on International Sales of Goods (CISG), which entered into force in 1988, has a very important place in the formation of uniform rules of law on the international sales contract. In the event of breach of the contract under the CISG, the foreseen type of permanent sanction is compensation. Regardless of whether the infringer is defective, the counterparty has the right to claim compensation. It is possible that both the actual losses and the loss of profits can be claimed in line with this right. However, this right is limited to the foreseeability principle, and the compensation to be paid is limited to the damages that the breach party ought to have foreseen or foresaw at the time the contract is established. In order to get rid of this compensation liability; the presence of an obstacle which is outside the control of the breach party and which is not possible to participate in the account at the time of the establishment of the contract and which is inevitable with its consequences is sought.
