The United Nations Convention on Contracts for the International Sale of Goods (CISG), also known as the Vienna Convention, is the primary international treaty governing cross-border sales of goods. It has been ratified by over 95 countries, including Australia, the United States, China, Germany, France, Japan, South Korea, and most of Australia’s major trading partners. The CISG sets out rules on contract formation, seller’s and buyer’s obligations, risk of loss, remedies for breach, and force majeure. It applies automatically to contracts between parties based in different Contracting States unless explicitly excluded.
