| 1 | Map the CISG’s geographic reach | The CISG may apply to an international sale of goods when the parties’ places of business are in different Contracting States. It may also apply through private international law rules, subject to applicable declarations. The parties’ nationalities are not the test. | Articles 1 and 95 | Record each party’s relevant place of business and check the CISG status, effective date, and any relevant declaration for each state involved. |
| 2 | State clearly whether the CISG applies | Choosing the law of a Contracting State does not, by itself, generally exclude the CISG, because the Convention forms part of that state’s applicable sales law. Parties may exclude it or vary many of its rules by agreement. | Article 6 | Use an express clause stating whether the CISG is included or excluded, and identify the domestic law that will govern matters outside the Convention. |
| 3 | Confirm that the transaction is a covered sale | The CISG excludes certain sales, including consumer purchases in specified circumstances, auctions, and sales of ships, vessels, hovercraft, or electricity. A contract for goods to be manufactured may be covered, but not if the buyer supplies a substantial part of the materials; contracts in which services or labor predominate are also excluded. | Articles 2 and 3 | Describe the goods, manufacturing obligations, buyer-supplied materials, and service components so the transaction’s legal classification can be assessed. |
| 4 | Define specifications and acceptance criteria | The seller generally must deliver goods that meet the contract’s agreed requirements for quantity, quality, description, packaging, and fitness for applicable purposes. The parties can set or modify these obligations in their contract. | Articles 35 and 36 | Attach measurable specifications, approved samples, testing methods, packaging requirements, and a written acceptance process to the agreement. |
| 5 | Inspect promptly and give specific notice | A buyer must examine the goods, or have them examined, within as short a period as is practicable in the circumstances. The buyer generally must notify the seller of a lack of conformity within a reasonable time after discovering it, specifying its nature; a two-year outer limit normally applies from handover, subject to the stated exception. | Articles 38 and 39 | Keep dated inspection records, photographs, test results, delivery documents, and written notices that identify the defect and affected goods. |
| 6 | Assess remedies before declaring the contract over | Avoidance generally requires a fundamental breach, or may be available in certain cases after an additional period for performance expires. The CISG also sets requirements and time limits for declarations of avoidance. | Articles 25, 47, 49, 63, and 64 | Document the breach, its consequences, any opportunity to cure, and the relevant notice dates before sending a termination or avoidance notice. |
| 7 | Separate damages, force majeure, and forum questions | Damages may include foreseeable loss and lost profit, subject to mitigation. Article 79 may exempt a party from damages for a qualifying impediment beyond its control, but it is not a blanket release from every remedy. The CISG does not generally determine court jurisdiction or arbitration procedure, and it does not govern every issue, including contract validity and the effect of the contract on property in the goods. | Articles 4, 74, 77, and 79 | Specify the dispute forum, arbitration arrangements if used, notice process, evidence preservation, and any separate rules that may govern limitation periods or issues outside the CISG. |
