International Trade Contracts Under Pressure: Why the CISG Matters More Than Ever
International Trade Contracts Under Pressure: Why the CISG Matters More Than Ever
In 2025, the global trading system absorbed its most significant shock in decades. Sweeping tariff increases, reshored supply chains, and renegotiated long-term supply agreements left legal teams worldwide scrambling to reassess the contracts governing their cross-border transactions. At the centre of most of those contracts — whether parties realised it or not — is the United Nations Convention on Contracts for the International Sale of Goods. The CISG now governs commercial sales between parties in 97 contracting states, covering the majority of global merchandise trade by volume. When contracts break down, when delivery is refused, when goods fail to conform — the CISG is the legal framework that determines what happens next.
Yet the CISG remains one of the most misunderstood instruments in international commercial law. Many legal practitioners default to domestic law when the CISG applies automatically. Others exclude it without understanding what they lose. And the case law — now spanning courts and arbitral tribunals across dozens of jurisdictions — evolves faster than any single practitioner can track. That is the gap this Encyclopedia fills.
What This Reference Provides
The Elgar Concise Encyclopedia of International Sales Law (CISG), edited by Franco Ferrari (NYU School of Law) and Marco Torsello (University of Verona) and published in April 2026, brings together over 120 alphabetically organised entries written by leading academics and practitioners from multiple jurisdictions. Each entry covers a specific legal concept or provision — acceptance, avoidance, conformity of goods, fundamental breach, passing of risk, remedies, usages — with direct references to case law from courts and arbitral tribunals worldwide.
This is not a commentary to read from beginning to end. It is a reference to reach for when a specific question arises: How does the CISG handle late acceptance? What constitutes fundamental breach in arbitration? When does risk pass in transit contracts? The 125 entries answer those questions precisely, with citations that allow practitioners to go deeper when necessary.

Q&A
Q: Does the CISG apply automatically to international sales contracts?
Yes — when both parties have their place of business in different CISG contracting states, the Convention applies automatically unless the parties expressly exclude it. As of 2025, 97 states have ratified the CISG, covering the majority of global merchandise trade. Many contracts are governed by the CISG without the parties being aware of it.
Q: What is fundamental breach under the CISG and why does it matter?
Under Article 25 of the CISG, a fundamental breach is one that substantially deprives the innocent party of what they were entitled to expect under the contract — and whose consequences the breaching party foresaw or should have foreseen. Only a fundamental breach entitles the innocent party to avoid the contract entirely.
Q: How does the CISG handle non-conforming goods?
The CISG requires goods to conform to the contract in quantity, quality, and description. The buyer must examine goods promptly and give notice of any non-conformity within a reasonable time. Remedies include repair, replacement, price reduction, or avoidance depending on the severity of the defect.
Q: Can parties opt out of the CISG?
Yes. Article 6 allows parties to exclude the Convention entirely. Exclusion must be express or clearly implied — simply specifying a domestic law does not automatically exclude the CISG. An explicit exclusion clause is advisable.
Q: How does the CISG interact with arbitration clauses?
The CISG applies in arbitration whenever it would apply in national court proceedings. Arbitral tribunals regularly apply the CISG even when not explicitly chosen. The Encyclopedia includes dedicated entries on CISG applicability in arbitration.
