The claim for damages in practice is the most important remedy under the CISG. The main prerequisite for claiming damages is the breach of a contractual obligation. It is important to note that the CISG in this regard does not distinguish between different breaches of contract like non-performance or delivery of non-conforming goods. The amount of damages that can be claimed is dealt with in Art. 74-77 while the possibility of exemption is governed by Art. 79, 80.
