The United Nations Convention on Contracts for the International Sale of Goods is divided into four parts: (1) Scope of application; (2) Establishment of the contract; (3) Commodity sales; (4) the final clause. Full text *** 10 1. The main contents of the Convention include the following four aspects: 1. Basic principles of the convention. The principles of establishing a new international economic order, equality and mutual benefit, and taking into account different social, economic and legal systems. These basic principles are the basis for the implementation, interpretation and revision of the Convention, and they are also the guidelines for handling and developing international trade relations. 2. Scope of application. First, the convention only applies to international contracts for the sale of goods, that is, contracts for the sale of goods concluded between two parties whose places of business are in different countries, but it is clearly stipulated that the convention cannot be applied to the international sale of certain goods. Secondly, this Convention applies to contracts where both parties have their places of business in Contracting States, but if the law of a Contracting State should be applied to the contract according to the conflict rules applicable to the contract, the CISG should also apply to this situation, regardless of whether the places of business of both parties to the contract are in that Contracting State. In this regard, States parties may declare reservations upon ratification or accession. Third, the parties may expressly stipulate in the contract that this Convention shall not apply. (The scope of application does not allow States parties to reserve) 3. The conclusion of the contract. Including the form of contract and the legal effect of offer and acceptance. 4. Rights and obligations of buyers and sellers. 1.

Second, the buyer's responsibility is mainly manifested in two obligations: paying the price of the goods; Collect goods. Third, the remedies for breach of contract by buyers and sellers are specified in detail. Fourthly, several situations of risk transfer are stipulated. Fifth, the meaning of fundamental breach of contract and expected breach of contract and the obligations that both parties should perform when this happens are clarified. Sixth, the conditions of tax exemption basis are clarified. Supplement: CISG (United Nations Convention on Contracts for the International Sale of Goods). Authorized by the United Nations General Assembly, the United Nations Conference on Contracts for the International Sale of Goods (Vienna Conference) was held in Vienna, Austria from March 65438 to April 1980, with the participation of representatives from 62 countries. The convention was adopted at this meeting. The 1988 Convention will enter into force after reaching the number of legally ratified countries. China submitted its instrument of ratification of the Convention to the Secretary-General of the United Nations in February 1986 and became a party to the Convention. However, when we joined the Convention, according to the provisions of Article 95 and Article 96, China made reservations on Article 1 1 and Article 1 item b of the Convention. The States parties to the United Nations Convention on Contracts for the International Sale of Goods (Vienna, April 1980, 1 1) believe that the development of international trade on the basis of equality and mutual benefit is an important factor in promoting friendly relations between countries, bearing in mind the broad objectives of the resolutions adopted by the sixth special session of the United Nations General Assembly on the establishment of a new international economic order. The adoption of uniform rules for international sales contracts that take into account different social, economic and legal systems will help to reduce legal obstacles and promote the development of international trade. It is hereby agreed as follows: Amend the scope of application and general provisions of the first part of this paragraph and amend the scope of application of the first chapter of this paragraph Article 1 (1) This Convention applies to the sale of goods concluded between parties whose places of business are in different countries. Or (b) if the rules of private international law lead to the application of the law of a Contracting State.

Article 8 (1) As far as this Convention is concerned, statements and other acts made by one party shall be interpreted according to his intention if the other party already knows or cannot be unaware of his intention.

(3) When determining the intention of a party or the understanding that a reasonable person should have, due consideration should be given to all the facts, including the negotiation situation, any customary practices and practices established between the parties and any subsequent actions of the parties. Article 9 (1) Any convention agreed by both parties and any convention established between both parties shall be binding on both parties. (2) Unless otherwise agreed, both parties shall be deemed to have tacitly agreed to apply the customary practices that both parties already know or should know to their contracts or the conclusion of contracts, which are well known and frequently observed by the parties to similar contracts involved in specific trade in international trade. Article 10 As far as this Convention is concerned: (a) If both parties have more than one place of business, the place of business which is most closely related to the contract and its performance shall be their place of business, but what both parties knew or envisaged at any time before or at the conclusion of the contract shall also be taken into account; (b) If the party has no place of business, reference shall be made to his habitual residence. Article 11 A sales contract does not need to be concluded or proved in writing, nor is it restricted by other formal conditions. The sales contract can be proved by any means, including witness. Article 12 Any provision in Article 11, Article 29 or Part II of this Convention that allows the sale contract or its modification or termination of the agreement, or any provision that any offer, acceptance or other expression of intention is made in any form other than writing, shall not apply. If either party has its place of business in a Contracting State that has made a declaration in accordance with Article 96 of this Convention, both parties may not derogate from this Article or change its effect. Article 13 For the purposes of this Convention, "writing" includes telegram and telex. Article 14 (1) A proposal to conclude a contract made to one or more specific persons constitutes an offer if it is absolutely certain and shows the intention of the offeror to be bound by it when it is accepted. If a proposal clearly specifies the goods and explicitly or implicitly specifies the quantity and price, or how to determine the quantity and price, the proposal is quite certain. (2) A proposal that is not made to one or more specific people shall only be regarded as an invitation to issue the starting price, unless the person who made the proposal clearly expresses the contrary intention. Article 15 (1) An offer takes effect when it reaches the offeree. (2) An offer, even if it is irrevocable, may be withdrawn if the notice of withdrawal reaches the offeree before or at the same time. Article 16 (1) Before the conclusion of a contract, an offer may be revoked, if the notice of revocation reaches the offeree before the offeree sends the acceptance notice. (2) However, an offer may not be revoked under any of the following circumstances: (1) The offer specifies the time limit for accepting the offer or otherwise indicates that the offer is irrevocable; Or (b) the offeree has reason to believe that the offer is irrevocable, and the offeree has trusted the offer. Article 17 An offer, even if it is irrevocable, shall be terminated upon notification that it has been refused to be delivered to the offeror. Article 18 (1) A statement or other act of the offeree expressing agreement with an offer is an acceptance, but silence or inaction does not in itself mean an acceptance. (2) The acceptance of an offer takes effect when the notice of consent reaches the offeror. If the notice of consent does not reach the offeror within the time specified by the offeror, if the time is not specified, the acceptance will be invalid within a reasonable time, but due consideration should be given to the transaction situation, including the rapid sequence of communication methods used by the offeror. The price of distribution must be accepted immediately, unless the situation is different. (3) However, if, according to the offer or the customary practices and practices established between the parties, the offeree can do some behavior, such as the behavior related to the delivery of goods or the payment of the price, to express his consent without giving notice to the offeror, the acceptance will take effect when the behavior is made, but the behavior must be made within the period specified in the preceding paragraph. Article 19 (1) A reply that accepts an offer but contains additions, restrictions or other changes is a rejection of the offer and constitutes a counter-offer. (2) However, an answer indicating acceptance of an offer, if the additions or different conditions contained therein do not substantially change the terms of the offer, will still constitute acceptance, unless the offeror objects to the different opinions orally or in writing within a certain period of time, without undue delay. If the offeror does not raise such objections, the terms of the contract shall be subject to the changes contained in the terms of the offer and the acceptance notice. (3) Additional or different conditions related to the price of goods, payment, quality and quantity of goods, place and time of delivery, scope of one party's liability to the other party, dispute settlement, etc. Are regarded as conditions for substantially changing the offer. Article 20 (1) The time limit for acceptance agreed by the offeror in a telegram or letter shall be counted from the date when the telegram or letter is sent, or from the date when the letter is not sent. The time limit for acceptance stipulated by the offeror by telephone, telex or other rapid communication means shall be counted from the time when the offer reaches the offeree. (2) When calculating the commitment period, legal holidays or non-business days within the commitment period shall be counted. However, if the acceptance notice does not reach the address of the offeror at the last 1 day of the acceptance period, because that day is a legal holiday or a non-business day at the business place of the offeror, the acceptance period will be postponed to the next business day. Article 21 (1) An overdue acceptance still has the effect of acceptance, if the offeror notifies the offeree of the intention orally or in writing without delay. (2) If the letter or other written document containing the overdue acceptance shows that it was sent under the condition of normal delivery and timely delivery to the offeror, the overdue acceptance has the effect of acceptance, unless the offeror informs the offeree orally or in writing without delay that he thinks his offer is invalid. Article 22 An acceptance may be withdrawn if the notice of withdrawal reaches the offeror before or at the same time as the acceptance should take effect. Article 23 A contract is concluded when the acceptance of an offer in accordance with the provisions of this Convention takes effect. Article 24 For the purposes of this Part of the Convention, an offer, acceptance or other expression of intention means "delivery" to the other party, that is, oral notification to the other party or face-to-face delivery to the other party or its business place or mailing address in any other way, or delivery to the other party's habitual residence if there is no business place or mailing address.

Article 26 A declaration declaring a contract invalid shall take effect after notifying the other party. Article 27 Unless otherwise specified in this Part of this Convention, after a party sends any notice, demand or other notice in a manner appropriate to the circumstances, if the notice is delayed, wrongly delivered or fails to arrive, it shall not deprive the party of the right to use the notice. Article 28 If, according to the provisions of this Convention, one party has the right to require the other party to perform an obligation, the court is not obliged to make a judgment requiring the specific performance of that obligation, unless the court is willing to do so according to its own laws for similar sales contracts that are not within the scope of this Convention. Article 29 (1) A contract may be modified or terminated by mutual agreement. (2) If the written contract stipulates that any modification or dissolution according to the agreement must be made in writing, it shall not be modified or dissolved according to the agreement in any other way.

Article 40 If the non-conformity of the goods refers to some facts that the seller knew or could not have known but did not inform the buyer, the seller has no right to invoke the provisions of Articles 38 and 39. Article 41 The goods delivered by the seller must be goods for which no third party can claim any rights or claims, unless the buyer agrees to collect the goods according to these rights or claims.
