400.2-318. Third party beneficiaries of warranties express or implied

A seller’s warranty whether express or implied extends to any natural person who is in the family or household of his buyer or who is a guest in his home if it is reasonable to expect that such person may use, consume or be affected by the goods and who is injured in person by breach of the warranty. A seller may not exclude or limit the operation of this section.

Prior Uniform Statutory Provision: None.


1. The last sentence of this section does not mean that a seller is precluded from excluding or disclaiming a warranty which might otherwise arise in connection with the sale provided such exclusion or modification is permitted by Section 2-316. Nor does that sentence preclude the seller from limiting the remedies of his own buyer and of any beneficiaries, in any manner provided in Sections 2-718 or 2-719. To the extent that the contract of sale contains provisions under which warranties are excluded or modified, or remedies for breach are limited, such provisions are equally operative against beneficiaries of warranties under this section. What this last sentence forbids is exclusion of liability by the seller to the persons to whom the warranties which he has made to his buyer would extend under this section.

2. The purpose of this section is to give the buyer’s family, household and guests the benefit of the same warranty which the buyer received in the contract of sale, thereby freeing any such beneficiaries from any technical rules as to “privity.” It seeks to accomplish this purpose without any derogation of any right or remedy resting on negligence. It rests primarily upon the merchant-seller’s warranty under this Article that the goods sold are merchantable and fit for the ordinary purposes for which such goods are used rather than the warranty of fitness for a particular purpose. Implicit in the section is that any beneficiary of a warranty may bring a direct action for breach of warranty against the seller whose warranty extends to him.

3. This section expressly includes as beneficiaries within its provisions the family, household, and guests of the purchaser. Beyond this, the section is neutral and is not intended to enlarge or restrict the developing case law on whether the seller’s warranties, given to his buyer who resells, extend to other persons in the distributive chain.

400.2-315. Implied warranty–fitness for particular purpose

Where the seller at the time of contracting has reason to know any particular purpose for which the goods are required and that the buyer is relying on the seller’s skill or judgment to select or furnish suitable goods there is unless excluded or modified under section 400.2-316 an implied warranty that the goods shall be fit for such purpose.

Prior Uniform Statutory Provision: Section 15(1), (4), (5), Uniform Sales Act.

Changes: Rewritten.

Purposes of Changes:

1. Whether or not this warranty arises in any individual case is basically a question of fact to be determined by the circumstances of the contracting. Under this section the buyer need not bring home to the seller actual knowledge of the particular purpose for which the goods are intended or of his reliance on the seller’s skill and judgment, if the circumstances are such that the seller has reason to realize the purpose intended or that the reliance exists. The buyer, of course, must actually be relying on the seller.

2. A “particular purpose” differs from the ordinary purpose for which the goods are used in that it envisages a specific use by the buyer which is peculiar to the nature of his business whereas the ordinary purposes for which goods are used are those envisaged in the concept of merchantability and go to uses which are customarily made of the goods in question. For example, shoes are generally used for the purpose of walking upon ordinary ground, but a seller may know that a particular pair was selected to be used for climbing mountains.

A contract may of course include both a warranty of merchantability and one of fitness for a particular purpose.

The provisions of this Article on the cumulation and conflict of express and implied warranties must be considered on the question of inconsistency between or among warranties. In such a case any question of fact as to which warranty was intended by the parties to apply must be resolved in favor of the warranty of fitness for particular purpose as against all other warranties except where the buyer has taken upon himself the responsibility of furnishing the technical specifications.

3. In connection with the warranty of fitness for a particular purpose the provisions of this Article on the allocation or division of risks are particularly applicable in any transaction in which the purpose for which the goods are to be used combines requirements both as to the quality of the goods themselves and compliance with certain laws or regulations. How the risks are divided is a question of fact to be determined, where not expressly contained in the agreement, from the circumstances of contracting, usage of trade, course of performance and the like, matters which may constitute the “otherwise agreement” of the parties by which they may divide the risk or burden.

4. The absence from this section of the language used in the Uniform Sales Act in referring to the seller, “whether he be the grower or manufacturer or not,” is not intended to impose any requirement that the seller be a grower or manufacturer. Although normally the warranty will arise only where the seller is a merchant with the appropriate “skill or judgment,” it can arise as to nonmerchants where this is justified by the particular circumstances.

5. The elimination of the “patent or other trade name” exception constitutes the major extension of the warranty of fitness which has been made by the cases and continued in this Article. Under the present section the existence of a patent or other trade name and the designation of the article by that name, or indeed in any other definite manner, is only one of the facts to be considered on the question of whether the buyer actually relied on the seller, but it is not of itself decisive of the issue. If the buyer himself is insisting on a particular brand he is not relying on the seller’s skill and judgment and so no warranty results. But the mere fact that the article purchased has a particular patent or trade name is not sufficient to indicate nonreliance if the article has been recommended by the seller as adequate for the buyer’s purposes.

6. The specific reference forward in the present section to the following section on exclusion or modification of warranties is to call attention to the possibility of eliminating the warranty in any given case. However it must be noted that under the following section the warranty of fitness for a particular purpose must be excluded or modified by a conspicuous writing.

400.2-314. Implied warranty–merchantability–usage of trade

(1) Unless excluded or modified (section 400.2-316), a warranty that the goods shall be merchantable is implied in a contract for their sale if the seller is a merchant with respect to goods of that kind. Under this section the serving for value of food or drink to be consumed either on the premises or elsewhere is a sale.

(2) Goods to be merchantable must be at least such as

(a) pass without objection in the trade under the contract description; and

(b) in the case of fungible goods, are of fair average quality within the description; and

(c) are fit for the ordinary purposes for which such goods are used; and

(d) run, within the variations permitted by the agreement, of even kind, quality and quantity within each unit and among all units involved; and

(e) are adequately contained, packaged, and labeled as the agreement may require; and

(f) conform to the promises or affirmations of fact made on the container or label if any.

(3) Unless excluded or modified (section 400.2-316) other implied warranties may arise from course of dealing or usage of trade.

1965 Main Volume Uniform Commercial Code Comment

Prior Uniform Statutory Provision: Section 15(2), Uniform Sales Act.

Changes: Completely rewritten.

Purposes of Changes: This section, drawn in view of the steadily developing case law on the subject, is intended to make it clear that:

1. The seller’s obligation applies to present sales as well as to contracts to sell subject to the effects of any examination of specific goods. (Subsection (2) of Section 2-316). Also, the warranty of merchantability applies to sales for use as well as to sales for resale.

2. The question when the warranty is imposed turns basically on the meaning of the terms of the agreement as recognized in the trade. Goods delivered under an agreement made by a merchant in a given line of trade must be of a quality comparable to that generally acceptable in that line of trade under the description or other designation of the goods used in the agreement. The responsibility imposed rests on any merchant-seller, and the absence of the words “grower or manufacturer or not” which appeared in Section 15(2) of the Uniform Sales Act does not restrict the applicability of this section.

3. A specific designation of goods by the buyer does not exclude the seller’s obligation that they be fit for the general purposes appropriate to such goods. A contract for the sale of second-hand goods, however, involves only such obligation as is appropriate to such goods for that is their contract description. A person making an isolated sale of goods is not a “merchant” within the meaning of the full scope of this section and, thus, no warranty of merchantability would apply. His knowledge of any defects not apparent on inspection would, however, without need for express agreement and in keeping with the underlying reason of the present section and the provisions on good faith, impose an obligation that known material but hidden defects be fully disclosed.

4. Although a seller may not be a “merchant” as to the goods in question, if he states generally that they are “guaranteed” the provisions of this section may furnish a guide to the content of the resulting express warranty. This has particular significance in the case of second-hand sales, and has further significance in limiting the effect of fine-print disclaimer clauses where their effect would be inconsistent with large-print assertions of “guarantee”.

5. The second sentence of subsection (1) covers the warranty with respect to food and drink. Serving food or drink for value is a sale, whether to be consumed on the premises or elsewhere. Cases to the contrary are rejected. The principal warranty is that stated in subsections (1) and (2)(c) of this section.

6. Subsection (2) does not purport to exhaust the meaning of “merchantable” nor to negate any of its attributes not specifically mentioned in the text of the statute, but arising by usage of trade or through case law. The language used is “must be at least such as . . .,” and the intention is to leave open other possible attributes of merchantability.

7. Paragraphs (a) and (b) of subsection (2) are to be read together. Both refer, as indicated above, to the standards of that line of the trade which fits the transaction and the seller’s business. “Fair average” is a term directly appropriate to agricultural bulk products and means goods centering around the middle belt of quality, not the least or the worst that can be understood in the particular trade by the designation, but such as can pass “without objection.” Of course a fair percentage of the least is permissible but the goods are not “fair average” if they are all of the least or worst quality possible under the description. In cases of doubt as to what quality is intended, the price at which a merchant closes a contract is an excellent index of the nature and scope of his obligation under the present section.

8. Fitness for the ordinary purposes for which goods of the type are used is a fundamental concept of the present section and is covered in paragraph (c). As stated above, merchantability is also a part of the obligation owing to the purchaser for use. Correspondingly, protection, under this aspect of the warranty, of the person buying for resale to the ultimate consumer is equally necessary, and merchantable goods must therefore be “honestly” resalable in the normal course of business because they are what they purport to be.

9. Paragraph (d) on evenness of kind, quality and quantity follows case law. But precautionary language has been added as a reminder of the frequent usages of trade which permit substantial variations both with and without an allowance or an obligation to replace the varying units.

10. Paragraph (e) applies only where the nature of the goods and of the transaction require a certain type of container, package or label. Paragraph (f) applies, on the other hand, wherever there is a label or container on which representations are made, even though the original contract, either by express terms or usage of trade, may not have required either the labelling or the representation. This follows from the general obligation of good faith which requires that a buyer should not be placed in the position of reselling or using goods delivered under false representations appearing on the package or container. No problem of extra consideration arises in this connection since, under this Article, an obligation is imposed by the original contract not to deliver mislabeled articles, and the obligation is imposed where mercantile good faith so requires and without reference to the doctrine of consideration.

11. Exclusion or modification of the warranty of merchantability, or of any part of it, is dealt with in the section to which the text of the present section makes explicit precautionary references. That section must be read with particular reference to its subsection (4) on limitation of remedies. The warranty of merchantability, wherever it is normal, is so commonly taken for granted that its exclusion from the contract is a matter threatening surprise and therefore requiring special precaution.

12. Subsection (3) is to make explicit that usage of trade and course of dealing can create warranties and that they are implied rather than express warranties and thus subject to exclusion or modification under Section 2-316. A typical instance would be the obligation to provide pedigree papers to evidence conformity of the animal to the contract in the case of a pedigreed dog or blooded bull.

13. In an action based on breach of warranty, it is of course necessary to show not only the existence of the warranty but the fact that the warranty was broken and that the breach of the warranty was the proximate cause of the loss sustained. In such an action an affirmative showing by the seller that the loss resulted from some action or event following his own delivery of the goods can operate as a defense. Equally, evidence indicating that the seller exercised care in the manufacture, processing or selection of the goods is relevant to the issue of whether the warranty was in fact broken. Action by the buyer following an examination of the goods which ought to have indicated the defect complained of can be shown as matter bearing on whether the breach itself was the cause of the injury.

400.2-313. Express warranties by affirmation, promise, description, sample

(1) Express warranties by the seller are created as follows:

(a) Any affirmation of fact or promise made by the seller to the buyer which relates to the goods and becomes part of the basis of the bargain creates an express warranty that the goods shall conform to the affirmation or promise.

(b) Any description of the goods which is made part of the basis of the bargain creates an express warranty that the goods shall conform to the description.

(c) Any sample or model which is made part of the basis of the bargain creates an express warranty that the whole of the goods shall conform to the sample or model.

(2) It is not necessary to the creation of an express warranty that the seller use formal words such as “warrant” or “guarantee” or that he have a specific intention to make a warranty, but an affirmation merely of the value of the goods or a statement purporting to be merely the seller’s opinion or commendation of the goods does not create a warranty.

1965 Main Volume Uniform Commercial Code Comment

Prior Uniform Statutory Provision: Sections 12, 14 and 16, Uniform Sales Act.

Changes: Rewritten.

Purposes of Changes: To consolidate and systematize basic principles with the result that:

1. “Express” warranties rest on “dickered” aspects of the individual bargain, and go so clearly to the essence of that bargain that words of disclaimer in a form are repugnant to the basic dickered terms. “Implied” warranties rest so clearly on a common factual situation or set of conditions that no particular language or action is necessary to evidence them and they will arise in such a situation unless unmistakably negated.

This section reverts to the older case law insofar as the warranties of description and sample are designated “express” rather than “implied”.

2. Although this section is limited in its scope and direct purpose to warranties made by the seller to the buyer as part of a contract for sale, the warranty sections of this Article are not designed in any way to disturb those lines of case law growth which have recognized that warranties need not be confined either to sales contracts or to the direct parties to such a contract. They may arise in other appropriate circumstances such as in the case of bailments for hire, whether such bailment is itself the main contract or is merely a supplying of containers under a contract for the sale of their contents. The provisions of Section 2-318 on third party beneficiaries expressly recognize this case law development within one particular area. Beyond that, the matter is left to the case law with the intention that the policies of this Act may offer useful guidance in dealing with further cases as they arise.

3. The present section deals with affirmations of fact by the seller, descriptions of the goods or exhibitions of samples, exactly as any other part of a negotiation which ends in a contract is dealt with. No specific intention to make a warranty is necessary if any of these factors is made part of the basis of the bargain. In actual practice affirmations of fact made by the seller about the goods during a bargain are regarded as part of the description of those goods; hence no particular reliance on such statements need be shown in order to weave them into the fabric of the agreement. Rather, any fact which is to take such affirmations, once made, out of the agreement requires clear affirmative proof. The issue normally is one of fact.

4. In view of the principle that the whole purpose of the law of warranty is to determine what it is that the seller has in essence agreed to sell, the policy is adopted of those cases which refuse except in unusual circumstances to recognize a material deletion of the seller’s obligation. Thus, a contract is normally a contract for a sale of something describable and described. A clause generally disclaiming “all warranties, express or implied” cannot reduce the seller’s obligation with respect to such description and therefore cannot be given literal effect under Section 2-316.

This is not intended to mean that the parties, if they consciously desire, cannot make their own bargain as they wish. But in determining what they have agreed upon good faith is a factor and consideration should be given to the fact that the probability is small that a real price is intended to be exchanged for a pseudo-obligation.

5. Paragraph (1)(b) makes specific some of the principles set forth above when a description of the goods is given by the seller.

A description need not be by words. Technical specifications, blueprints and the like can afford more exact description than mere language and if made part of the basis of the bargain goods must conform with them. Past deliveries may set the description of quality, either expressly or impliedly by course of dealing. Of course, all descriptions by merchants must be read against the applicable trade usages with the general rules as to merchantability resolving any doubts.

6. The basic situation as to statements affecting the true essence of the bargain is no different when a sample or model is involved in the transaction. This section includes both a “sample” actually drawn from the bulk of goods which is the subject matter of the sale, and a “model” which is offered for inspection when the subject matter is not at hand and which has not been drawn from the bulk of the goods.

Although the underlying principles are unchanged, the facts are often ambiguous when something is shown as illustrative, rather than as a straight sample. In general, the presumption is that any sample or model just as any affirmation of fact is intended to become a basis of the bargain. But there is no escape from the question of fact. When the seller exhibits a sample purporting to be drawn from an existing bulk, good faith of course requires that the sample be fairly drawn. But in mercantile experience the mere exhibition of a “sample” does not of itself show whether it is merely intended to “suggest” or to “be” the character of the subject-matter of the contract. The question is whether the seller has so acted with reference to the sample as to make him responsible that the whole shall have at least the values shown by it. The circumstances aid in answering this question. If the sample has been drawn from an existing bulk, it must be regarded as describing values of the goods contracted for unless it is accompanied by an unmistakable denial of such responsibility. If, on the other hand, a model of merchandise not on hand is offered, the mercantile presumption that it has become a literal description of the subject matter is not so strong, and particularly so if modification on the buyer’s initiative impairs any feature of the model.

7. The precise time when words of description or affirmation are made or samples are shown is not material. The sole question is whether the language or samples or models are fairly to be regarded as part of the contract. If language is used after the closing of the deal (as when the buyer when taking delivery asks and receives an additional assurance), the warranty becomes a modification, and need not be supported by consideration if it is otherwise reasonable and in order (Section 2-209).

8. Concerning affirmations of value or a seller’s opinion or commendation under subsection (2), the basic question remains the same: What statements of the seller have in the circumstances and in objective judgment become part of the basis of the bargain? As indicated above, all of the statements of the seller do so unless good reason is shown to the contrary. The provisions of subsection (2) are included, however, since common experience discloses that some statements or predictions cannot fairly be viewed as entering into the bargain. Even as to false statements of value, however, the possibility is left open that a remedy may be provided by the law relating to fraud or misrepresentation.
