The States Parties to this Convention,

Considering that the development of international trade on the basis of equality and mutual benefit is an important element in promoting friendly relations among States,

Article 73

• In the case of a contract for delivery of goods by instalments, if the failure of one party to perform any of his obligations in respect of any instalment constitutes a fundamental breach of contract with respect to that instalment, the other party may declare the contract avoided with respect to that

• A buyer who declares the contract avoided in respect of any delivery may, at the same time, declare it avoided in respect of deliveries already made or of future deliveries if, by reason of their interdependence, those deliveries could not be used for the purpose contemplated by the parties at  the time of the conclusion of the

Section II.     Damages

Article 74

Damages for breach of contract by one party consist of a sum equal to the loss, including loss of profit, suffered by the other party as a consequence of the breach. Such damages may not exceed the loss which the party in breach foresaw or ought to have  foreseen at the time of the conclusion of   the contract, in the light of the facts and matters of which he then knew or ought to have known, as a possible consequence of the breach of contract.

Article 75

If the contract is avoided and if, in a reasonable manner and within a reasonable time after avoidance, the buyer has bought goods in replacement or the seller has resold the goods, the party claiming damages may recover the difference between the contract price and the price in the substitute transaction as well as any further damages recoverable under article 74.

Article 76

• If the contract is avoided and there is a current price for the goods, the party claiming damages may, if he has not made a purchase or resale under article 75, recover the difference between the price fixed by the contract and the current price at the time of avoidance as well as any further damages recoverable under article 74. If, however, the party claiming damages has avoided the contract after taking over the goods, the current price at the time of such taking over shall be applied instead of the current price at the time  of

• For the purposes of the preceding paragraph, the current price is the price prevailing at the place where delivery of the goods should have  been made or,  if there is no current price at that place, the price at such  other place as serves as a reasonable substitute, making due allowance for differences in the cost of transporting the

Article 77

A party who relies on a breach of contract must take such measures as are reasonable in the circumstances to mitigate the loss, including loss of profit, resulting from the breach.

• The party who fails to perform must give notice to the other party of the impediment and its effect on his ability to perform. If the notice is    not received by the other party within a reasonable time after the party who fails to perform knew or ought to have  known of the impediment, he is  liable for damages resulting from such non-receipt.

II.  explanatory Note by the UNCItRAL Secretariat on the United Nations Convention

on Contracts for the International Sale of Goods

 This note has been prepared by the Secretariat of the United Nations Commission on International Trade  Law for informational purposes; it is  not an official commentary on the Convention. 

Introduction

1. The United Nations Convention on Contracts for the International Sale of Goods provides a uniform text of law for international sales of The Convention was prepared by the United Nations Commission on International Trade Law (UNCITRAL) and adopted by a diplomatic conference on 11 April 1980.

2. Preparation of a uniform law for the international sale of goods began  in 1930 at the International Institute for the Unification of Private Law (UNIDROIT) in Rome. After a long interruption in the work as a result of  the Second World War,  the draft was submitted to a diplomatic conference  in The Hague in 1964, which adopted two conventions, one on the international sale of goods and the other on the formation of contracts for the international sale of

3. Almost immediately upon the adoption of the two conventions there was widespread criticism of their provisions as reflecting primarily the legal traditions and economic realities of continental Western Europe, which was the region that had most actively contributed to their preparation. As a result, one of the first tasks undertaken by UNCITRAL on its organization in 1968 was to enquire of States whether or not they intended to adhere to those conventions and the reasons for their positions. In the light of the responses received, UNCITRAL decided to study the two conventions to ascertain which modifications might render them capable of wider acceptance by countries of different legal, social and economic systems. The result of this study was the adoption by diplomatic conference on 11 April 1980 of the

33

34                                   United Nations Convention on Contracts for the International Sale of Goods 

United Nations Convention on Contracts for the International Sale of Goods, which combines the subject matter of the two prior conventions.

4. UNCITRAL’s success in preparing a Convention with wider acceptability is evidenced by the fact that the original eleven States for which the Convention came into force on 1 January 1988 included States from every geographical region, every stage of economic development and every major legal, social and economic The original eleven States were: Argentina, China, Egypt, France, Hungary, Italy, Lesotho, Syria, United States, Yugoslavia and Zambia.

5. As of 1 September 2010, 76 States are parties to the Convention. The current updated status of the Convention is available on the UNCITRAL website.1 Authoritative information on the status of the Convention, as well  as on related declarations, including with respect to territorial application and succession of States, may be found on the United Nations Treaty Collection on the 2

6. The Convention is divided into four parts. Part One deals with the scope of application of the Convention and the general provisions. Part Two contains the rules governing the formation of contracts for the international sale of goods. Part Three deals with the substantive rights and obligations of buyer and seller arising from the contract. Part Four contains the final clauses of the Convention concerning such matters as how and when  it comes into force, the reservations and declarations that are permitted and   the application of the Convention to international sales where both States concerned have the same or similar law on the

Part one.     Scope of application and general provisions

A.        Scope of application 

7. The articles on scope of application indicate both what is covered by the Convention and what is not covered. The Convention applies to contracts of sale of goods between parties whose places of business are in different States and either both of those States are Contracting States or the rules of private international law lead to the law of a Contracting State. A few States have  availed themselves of the authorization in article 95 to declare that  they would apply the Convention only in the former and not in the latter of these two As the Convention becomes more widely adopted, the

1. Explanatory Note 35

practical significance of such a declaration will diminish. Finally, the Convention may also apply as the law applicable to the contract if so chosen by the parties. In that case, the operation of the Convention will be subject   to any limits on contractual stipulations set by the otherwise applicable law.

8. The final clauses make two additional restrictions on the territorial scope of application that will be relevant to a few One applies only if a  State is a party to another international agreement that contains provisions concerning matters governed by this Convention; the other permits States that have the same or similar domestic law of sales to declare that the Convention does not apply between them.

9. Contracts of sale are distinguished from contracts for services in two respects by article 3. A contract for the supply of goods to be manufactured or produced is considered to be a sale unless the party who orders the goods undertakes to supply a substantial part of the materials necessary for their manufacture or production. When the preponderant part of the obligations   of the party who furnishes the goods consists in the supply of labour or   other services, the Convention does not

10. The Convention contains a list of types of sales that are excluded from the Convention, either because of the purpose of the sale (goods bought for personal, family or household use), the nature of the sale (sale by auction, on execution or otherwise by law) or the nature of the goods (stocks, shares, investment securities, negotiable instruments, money, ships, vessels, hovercraft, aircraft or electricity). In many States some or all of such sales are governed by special rules reflecting their special

11. Several articles make clear that the subject matter of the Convention is restricted to formation of the contract and the rights and duties of the buyer and seller arising from such a contract. In particular, the Convention is not concerned with the validity of the contract, the effect which the contract may have on the property in the goods sold or the liability of the seller for death or personal injury caused by the goods to any

B.        Party autonomy 

12. The basic principle of contractual freedom in the international sale of goods is recognized by the provision that permits the parties to exclude the application of this Convention or derogate from or vary  the effect  of any  of its This exclusion will occur, for example, if parties  choose  the  law of a non-contracting State or the substantive domestic law of a contracting State as the law applicable to the contract. Derogation from the Convention

36                                   United Nations Convention on Contracts for the International Sale of Goods 

will occur whenever a provision in the contract provides a different rule from that found in the Convention.

C.        Interpretation of the Convention 

13. This Convention for the unification of the law governing the international sale of goods will better fulfil its purpose if it is interpreted in a consistent manner in all legal systems. Great care was taken in its preparation to make it as clear and easy to understand as possible. Nevertheless, disputes will arise as to its meaning and application. When this occurs, all parties, including domestic courts and arbitral tribunals, are admonished to observe its international character and to promote uniformity in its application and  the observance of good faith in international trade. In particular, when a question concerning a matter governed by this Convention is not expressly settled in it, the question is to be settled in conformity with the general principles on which the Convention is based. Only in the absence of such principles should the matter be settled in conformity with the law applicable by virtue of the rules of private international

D.        Interpretation of the contract; usages 

14. The Convention contains provisions on the manner in which statements and conduct of a party are to be interpreted in the context of the formation  of the contract or its Usages agreed to by the parties, practices they have established between themselves and usages of which the parties knew or ought to have known and which are widely known to, and regularly observed by, parties to contracts of the type involved in the particular trade concerned may all be binding on the parties to the contract of sale.

E.        Form of the contract 

15. The Convention does not subject the contract of sale to any requirement as to form. In particular, article 11 provides that no written agreement is necessary for the conclusion of the contract. However, if the contract is in writing and it contains a provision requiring any modification or termination by agreement to be in writing, article 29 provides that the contract may not be otherwise modified or terminated by agreement. The only exception is that a party may be precluded by his conduct from asserting such a provision to the extent that the other person has relied on that

16. In order to accommodate those States whose legislation requires contracts of sale to be concluded in or evidenced by writing, article 96 entitles those

1. Explanatory Note 37

States to declare that neither article 11 not the exception to article 29 applies where any party to the contract has his place of business in that State.

Part two.     Formation of the contract

17. Part Two of the Convention deals with a number of questions that arise in the formation of the contract by the exchange of an offer and an When the formation of the contract takes place in this manner,  the contract  is concluded when the acceptance of the offer becomes effective.

18. In order for a proposal for concluding a contract to constitute an offer, it must be addressed to one or more specific persons and it must be sufficiently definite. For the proposal to be sufficiently definite, it must indicate the goods and expressly or implicitly fix or make provisions for determining the quantity and the

19. The Convention takes a middle position between the doctrine of the revocability of the offer until acceptance and its general irrevocability for some period of The general rule is that an offer may be revoked. However, the revocation must reach the offeree before he has dispatched an acceptance. Moreover, an offer cannot be revoked if it indicates that it is irrevocable, which it may do by stating a fixed time for acceptance or otherwise. Furthermore, an offer may not be revoked if it was reasonable for the offeree  to rely  on the offer as being irrevocable and the offeree has acted in reliance on the offer.

20. Acceptance of an offer may be made by means of a statement or other conduct of the offeree indicating assent to the offer that is communicated to the However, in some cases the acceptance may consist of performing an act, such as dispatch of the goods or payment of the price. Such an act would normally be effective as an acceptance the moment the  act was performed.

21. A frequent problem in contract formation, perhaps especially in regard to contracts of sale of goods, arises out of a reply to an offer that purports to be an acceptance but contains additional or different terms. Under the Convention, if the additional or different terms do not materially alter the terms of the offer, the reply constitutes an acceptance, unless the offeror without undue delay objects to those terms. If he does not object, the terms  of the contract are the terms of the offer with the modifications contained     in the

22. If the additional or different terms do materially alter the terms of the contract, the reply constitutes a counter-offer that must in turn be accepted

38     United Nations Convention on Contracts for the International Sale of Goods 

for a contract to be concluded. Additional or different terms relating,  among other things, to the price, payment, quality and quantity of the goods, place and time of delivery, extent of one party’s liability to the other or settlement of disputes are considered to alter the terms of the offer materially.

Part three.    Sale of goods

 A.        Obligations of the seller 

23. The general obligations of the seller are to deliver the goods, hand  over any documents relating to them and transfer the property  in  the  goods, as required by the contract and this Convention. The Convention provides supplementary rules for use in the absence of contractual agreement as to when, where and how the seller must perform these

24. The Convention provides a number of rules that implement the seller’s obligations in respect of the quality of the goods. In general, the seller must deliver goods that are of the quantity, quality and description required by the contract and that are contained or packaged in the manner required by  the contract. One set of rules of particular importance in international sales  of goods involves the seller’s obligation to deliver goods that are free from any right or claim of a third party, including rights based on industrial property or other intellectual

25. In connection with the seller’s obligations in regard to the quality of the goods, the Convention contains provisions on the buyer’s obligation to inspect the goods. He must give notice of any lack of conformity with the contract within a reasonable time after he has discovered it or ought to have discovered it, and at the latest two years from the date on which the goods were actually handed over to the buyer, unless this time limit is inconsistent with a contractual period of

B.        Obligations of the buyer

26. The general obligations of the buyer are to pay the price for the goods and take delivery of them as required by the contract and the Convention. The Convention provides supplementary rules for use in the absence of contractual agreement as to how the price is to be determined and where and when the buyer should perform his obligations to pay the

1. Explanatory Note 39

C.        Remedies for breach of contract

27. The remedies of the buyer for breach of contract by the seller are set forth in connection with the obligations of the seller and the remedies of the seller are set forth in connection with the obligations of the This makes it easier to use and understand the Convention.

28. The general pattern of remedies is the same in both cases. If all the required conditions are fulfilled, the aggrieved party may require performance of the other party’s obligations, claim damages or avoid the contract. The buyer also has the right to reduce the price where the goods delivered do not conform with the

29. Among the more important limitations on the right of an aggrieved party to claim a remedy is the concept of fundamental breach. For a breach  of contract to be fundamental, it must result in such detriment to the other party as substantially to deprive him of what he is entitled to expect under  the contract, unless the result was neither foreseen by the party in breach   nor foreseeable by a reasonable person of the same kind in the same circumstances. A buyer can require the delivery of substitute goods only if the goods delivered were not in conformity with the contract and the lack    of conformity constituted a fundamental breach of contract. The existence    of a fundamental breach is one of the two circumstances that justifies a declaration of avoidance of a contract by the aggrieved party; the other circumstance being that, in the case of non-delivery of the goods by the  seller or non-payment of the price or failure to take delivery by the buyer,   the party in breach fails to perform within a reasonable period of time fixed by the aggrieved

30. Other remedies may be restricted by special circumstances. For example, if the goods do not conform with the contract, the buyer may require the seller to remedy the lack of conformity by repair, unless this is unreasonable having regard to all the A party cannot recover damages that he could have mitigated by taking the proper measures. A party may be exempted from paying damages by virtue of an impediment beyond his control.

D.        Passing of risk

31. Determining the exact moment when the risk of loss or damage to the goods passes from the seller to the buyer is of great importance in contracts for the international sale of goods. Parties may regulate the issue in their contract either by an express provision or by the use of a trade term such as, for example, an The effect of the choice of such a term

would be to amend the corresponding provisions of the CISG accordingly. However, for the frequent case where the contract does not contain such a provision, the Convention sets forth a complete set of rules.

32. The two special situations contemplated by the Convention are when the contract of sale involves carriage of the goods and when the goods are sold while in transit. In all other cases the risk passes to the buyer when he takes over the goods or from the time when the goods are placed at his disposal and he commits a breach of contract by failing to take delivery, whichever comes first. In the frequent case when the contract relates to goods that are not then identified, they  must be identified to the contract before they can be considered to be placed at the disposal of the buyer and the risk of their loss can be considered to have passed to

E.        Suspension of performance and anticipatory breach

33. The Convention contains special rules for the situation in which, prior to the date on which performance is due, it becomes apparent that one of    the parties will not perform a substantial part of his obligations or will commit a fundamental breach of contract. A distinction is drawn between those cases in which the other party may suspend his own performance of   the contract but the contract remains in existence awaiting future events and those cases in which he may declare the contract

F.       Exemption from liability to pay damages

34. When a party fails to perform any of his obligations due to an impediment beyond his control that he could not reasonably have been expected to take into account at the time of the conclusion of the contract and that he could not have avoided or overcome, he is exempted from the consequences of his failure to perform, including the payment of damages. This exemption may also apply if the failure is due to the failure of a third person whom he has engaged to perform the whole or a part of the contract. However, he is subject to any other remedy, including reduction of the price, if the goods were defective in some

G.        Preservation of the goods

35. The Convention imposes on both parties the duty to preserve any goods in their possession belonging to the other Such a duty is of even greater importance in an international sale of goods where the other party is from a

foreign country and may not have agents in the country where the goods are located. Under certain circumstances the party in possession of the goods may sell them, or may even be required to sell them. A party selling the goods has the right to retain out of the proceeds of sale an amount equal to the reasonable expenses of preserving the goods and of selling them and  must account to the other party for the balance.

Part Four.    Final clauses

36. The final clauses contain the usual provisions relating to the Secretary- General as depositary and providing that the Convention is subject to ratification, acceptance or approval by those States that signed it by 30 September 1981, that it is open to accession by all States that are not signatory States and that   the text is equally authentic in Arabic, Chinese, English, French, Russian and

37. The Convention permits a certain number of declarations. Those relative to scope of application and the requirement as to a written contract have been mentioned above. There is a special declaration for States that have different systems of law governing contracts of sale in different parts of   their territory. Finally, a State may declare that it will not be bound by Part   II on formation of contracts or Part III on the rights and obligations of the buyer and seller. This latter declaration was included as part of the decision to combine into one convention the subject matter of the two 1964 Hague Conventions.

Complementary texts

38. The United Nations Convention on Contracts for the International Sale of Goods is complemented by the United Nations Convention on the Limitation Period in the International Sale of Goods, 1974, as amended by a Protocol in 1980 (the Limitation Convention). The Limitation Convention establishes uniform rules governing the period of time within which a party under a contract for the international sale of goods must commence legal proceedings against another party to assert a claim arising from the contract or relating to its breach, termination or The amending Protocol of 1980 ensures that the scope of application of the Limitation Convention is identical to the one of the United Nations Convention on Contracts for the International Sale of Goods.

39. The United Nations Convention on Contracts for the International Sale of Goods is also complemented, with respect to the use of electronic communications,

42                                   United Nations Convention on Contracts for the International Sale of Goods

by the United Nations Convention on the Use of Electronic Communications in International Contracts, 2005 (the Electronic Communications Convention). The Electronic Communications Convention aims at facilitating the use of electronic communications in international trade by assuring that contracts concluded and other communications exchanged electronically are as valid and enforceable as their traditional paper-based equivalents. The Electronic Communications Con- vention may help to avoid misinterpretation of the CISG that might occur, for example, when a State has lodged a declaration mandating the use of the traditional written form for contracts for the international sale of goods. It may also promote the understanding that the “communication” and/or “writing” under the CISG should be construed so as to include electronic communications. The Electronic Communications Convention is an enabling treaty whose effect is to  remove those formal obstacles by establishing the requirements for functional equivalence between electronic and traditional written form.
