International Sales Law

International sales law is undergoing profound change. Digitalisation, new modes of contract formation, sustainability requirements and geopolitical tensions are reshaping cross-border trade. The fully revised third edition addresses these developments and offers a comprehensive account of international sales law in a rapidly changing commercial environment.

At its heart is a “CISG plus” approach: while the CISG provides the point of departure, its framework is complemented by comparative perspectives and relevant sources of hard and soft law. The Treatise draws in particular on the UNIDROIT Principles (PICC), the Principles of European Contract Law (PECL), selected national legal systems, trade usages and the INCOTERMS as a key instrument of international commercial practice. In this way, it traces the entire life cycle of an international sales contract, from negotiations and formation through performance, breach and remedies to continuing post-contractual obligations. Legal analysis is closely linked to illustrations, contract clauses and practical guidance.

The third edition introduces new chapters on merger and no oral modification clauses and on the CISG and supply chain due diligence. Case law, scholarship and legislation have been thoroughly updated, while increased attention is devoted to the digital transformation of international commerce, including electronic communications and automated contract formation.
