Warranty Clause: Express, Implied, and Disclaimed

A warranty clause is the contract's promise about quality: it states what the product or service is guaranteed to be or do, for how long, and what the buyer gets if that promise fails. It has two faces. One side (the seller) uses it to make just enough of a commitment to close the deal while disclaiming everything else. The other side (the buyer) uses it to lock in the specific assurances they are paying for. Get the express warranties, the implied ones, and the disclaimer language right and the clause tells you exactly who eats the cost of a defect. Get them wrong and you find out in litigation.

Reviewed and corrected on 12 October 2026. This is general information, not legal advice; check the cited statute or opinion before relying on it. The warranty periods and negotiating positions on this page are drafting practice, not legal rules. UCC text is the uniform text as published by Cornell's Legal Information Institute, and your state's version may differ.

TL;DR

• A warranty clause makes express promises about the product or service and, unless you disclaim them, the law adds implied warranties (merchantability and fitness for a particular purpose) under UCC Article 2 for sales of goods.
• Under the uniform UCC text, to exclude the implied warranty of merchantability the language must mention merchantability and, in a writing, be conspicuous; a fitness disclaimer must be a conspicuous writing. Language like "as is" or "with all faults" that calls the buyer's attention to the exclusion also removes the implied warranties (2-316(3)(a)).
• A warranty is not a representation and not an indemnity. A representation is a statement of present fact that supports a misrepresentation claim; a warranty is a promise the thing will be as stated and supports a breach-of-contract claim; an indemnity is a promise to pay for a third party's loss.
• The clause is only as strong as its remedy and its survival period. "Repair or replace" plus a tight time limit is the seller's friend; a broader remedy plus a longer survival window is the buyer's.
• The most expensive miss is a warranty that reads well but is quietly gutted by the disclaimer, the exclusive remedy, and the liability cap two sections later. Read all four together.

What a warranty clause actually does

A warranty clause allocates the risk of the deliverable not being what it was supposed to be. It works through three moving parts, and confusing them is the usual drafting error.

1. Express warranties (the promises you write down). These are the affirmative statements a party makes about the goods or services: the software will perform materially in accordance with the documentation, the goods conform to spec, the seller has good title. Under UCC 2-313, an express warranty is created by any affirmation of fact, promise, description, or sample that becomes part of the basis of the bargain. The section says it is not necessary that the seller use "formal words such as 'warrant' or 'guarantee'," though a statement merely of the goods' value or the seller's opinion or commendation does not create a warranty.

2. Implied warranties (the ones the law adds for you). In a sale of goods, the law supplies warranties whether or not you write them. The warranty of merchantability (UCC 2-314) is implied if the seller is a merchant with respect to goods of that kind, and requires that goods be, among other things, "fit for the ordinary purposes for which such goods are used." The warranty of fitness for a particular purpose (UCC 2-315) applies where the seller "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." These attach automatically and stay attached until disclaimed.

3. The disclaimer and the remedy (the limits). The disclaimer removes what was not promised (often "all other warranties, express or implied"). The exclusive remedy says what the buyer actually gets when a warranty is breached (repair, replace, refund) and, ideally for the seller, caps recovery there. The warranty promise and the remedy for its breach are separate levers; negotiate them separately.

Why it matters: the dollars at stake

Picture a $250,000 order of industrial components. The buyer tells the seller the parts are going into a food-processing line that runs at high temperature, and relies on the seller to pick components rated for it. The seller ships parts that meet the written spec sheet but fail at operating temperature. A batch of product is contaminated and the buyer's downtime and recall run to $1.2M.

• If the contract has a conspicuous "AS IS" disclaimer and an exclusive repair-or-replace remedy, the buyer's recovery may be limited to replacement parts worth a few thousand dollars.
• If the seller knew the particular purpose and the implied warranty of fitness was never disclaimed, and the buyer can show the exclusive remedy failed of its essential purpose, the buyer may reach consequential damages and recover a large share of the $1.2M.

Same parts, same failure, a seven-figure swing decided by whether the implied warranties were disclaimed and whether the remedy holds. That is why in-house counsel read this clause line by line rather than skimming it as boilerplate.

Who wants what

The pattern: the buyer wants specific, durable promises with a real remedy behind them, and the seller wants a narrow promise, everything else disclaimed, and a single capped remedy so the downside is predictable.

Market-standard language

A typical express warranty plus disclaimer for a goods-or-software deal reads close to this:

WARRANTIES.

(a) Express Warranty. Seller warrants that, for a period of twelve (12)
months from delivery (the "Warranty Period"), the Products will (i)
conform in all material respects to the specifications set forth in
Exhibit A and (ii) be free from material defects in materials and
workmanship under normal use.

(b) Exclusive Remedy. Buyer's sole and exclusive remedy, and Seller's
entire liability, for breach of the warranty in Section (a) is, at
Seller's option, repair or replacement of the non-conforming Product or
refund of the price paid for it, provided Buyer notifies Seller in
writing during the Warranty Period.

(c) Disclaimer. EXCEPT FOR THE EXPRESS WARRANTY IN SECTION (a), THE
PRODUCTS ARE PROVIDED "AS IS," AND SELLER DISCLAIMS ALL OTHER
WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE AND ANY WARRANTY
ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.

The all-caps styling in Section (c) does legal work. Under UCC 2-316(2), a disclaimer of merchantability must mention merchantability and, in a writing, be conspicuous, and a disclaimer of fitness must be in writing and conspicuous. UCC 1-201(b)(10) defines "conspicuous" as "so written, displayed, or presented that a reasonable person against which it is to operate ought to have noticed it" and lists a heading in capitals, or language in larger or contrasting type, font or color, as examples. A court decides whether a term is conspicuous, so capitals or bold are a safeguard, not a guarantee.

The negotiation: standard, fallback, walk-away

Treat the promise, the remedy, and the survival period as three separate trades.

The workhorse compromise is a specific, material-conformance express warranty for a defined period, an exclusive repair-or-replace remedy, and a written acknowledgment that if that remedy fails of its essential purpose the buyer's other remedies revive. That gives the seller a predictable cap in the normal case and gives the buyer a floor when the seller cannot actually fix the problem.

Common variations

Warranty clauses shift shape by deal type. The high-frequency variants:

• Services warranty. Instead of conformance to spec, the seller warrants that services will be performed in a "professional and workmanlike manner" by qualified personnel. Note that UCC Article 2 governs goods, not services, so the implied-warranty analysis differs for pure service contracts and is governed by common law.
• Software / SaaS warranty. "The software will perform materially in accordance with the documentation," usually paired with a disclaimer that the software will not be error-free or uninterrupted. Often bundled with a service-level commitment rather than a goods-style warranty.
• Title and non-infringement warranty. In a sale of goods, UCC 2-312(1) implies a warranty that the title conveyed is good and its transfer rightful, and 2-312(3) says that, "[u]nless otherwise agreed," a merchant seller regularly dealing in goods of the kind warrants that they are delivered free of the rightful claim of a third person "by way of infringement or the like." The title warranty "will be excluded or modified only by specific language or by circumstances which give the buyer reason to know" the seller does not claim title (2-312(2)). The infringement piece typically routes to an IP indemnity, not the repair-or-replace remedy.
• Pass-through / limited manufacturer warranty. A reseller passes the manufacturer's warranty through and disclaims its own, so the buyer's recourse runs to the manufacturer.
• "AS IS" sale. The whole thing sold with no express warranty and all implied warranties disclaimed. Common for used equipment, distressed assets, and some M&A asset deals.

Jurisdiction and enforceability notes

Warranty clauses are routinely enforced between sophisticated commercial parties, but several rules can override the drafting. Checked against the sources named on 12 October 2026:

• Conspicuousness for implied-warranty disclaimers. Under UCC 2-316(2), a disclaimer of merchantability must mention that word and, in writing, be conspicuous; a fitness disclaimer must be written and conspicuous. "As is" language works under 2-316(3)(a) if it "calls the buyer's attention to the exclusion of warranties and makes plain that there is no implied warranty." A disclaimer buried in lower-case boilerplate risks being held ineffective.
• Failure of essential purpose. Under UCC 2-719(2), "Where circumstances cause an exclusive or limited remedy to fail of its essential purpose, remedy may be had as provided in this Act." Courts disagree on whether a separate consequential-damages exclusion survives. The Third Circuit, predicting New Jersey law, treated it as an independent provision, "valid unless unconscionable," and enforced it (Chatlos Systems, Inc. v. National Cash Register Corp., 635 F.2d 1081 (3d Cir. 1980)). The Ninth Circuit, applying California law, upheld consequential damages where the seller's default was "so total and fundamental" that the limitation was "expunged from the contract" (RRX Industries, Inc. v. Lab-Con, Inc., 772 F.2d 543 (9th Cir. 1985)). Draft the two as independent provisions.
• When the warranty claim must be filed. Under the uniform UCC 2-725(2), "A breach of warranty occurs when tender of delivery is made, except that where a warranty explicitly extends to future performance of the goods and discovery of the breach must await the time of such performance the cause of action accrues when the breach is or should have been discovered." The limitations period runs from that accrual, so a warranty period that is long on paper may still leave a short time to sue.
• Consumer transactions. The federal Magnuson-Moss Warranty Act applies to written warranties on "consumer products," meaning tangible personal property "normally used for personal, family, or household purposes" (15 U.S.C. 2301(1)). The FTC's rule says the test is the type of product, not the buyer: the Act covers products "used for both personal and commercial purposes," such as automobiles, and ambiguity is resolved in favor of coverage (16 C.F.R. 700.1(a)). A business that buys a consumer product can therefore fall inside the Act. State law adds more. Massachusetts, for example, makes language by a seller or manufacturer of consumer goods that attempts to exclude implied warranties of merchantability and fitness unenforceable (Mass. Gen. Laws ch. 106, section 2-316A(2)), and California's Song-Beverly Act makes an "as is" sale of consumer goods ineffective to disclaim the implied warranties unless a conspicuous writing attached to the goods gives the notices the statute lists (Civ. Code 1792.4). The disclaimer rules for consumer goods are described in more detail on the warranty disclaimer page.
• UCC vs common law. UCC Article 2 applies to transactions in goods. Pure services, real estate, and IP licenses fall under common law or other statutes, where implied warranties and disclaimer rules differ. Identify what is actually being sold before you rely on the UCC analysis. How courts classify software and SaaS varies, and we did not survey it.
• Statutory and product-liability duties. A private disclaimer does not limit what a statute imposes. Under UCC 2-719(3), limiting consequential damages for injury to the person in the case of consumer goods is prima facie unconscionable, and Massachusetts makes disclaimers of the implied warranties unenforceable with respect to injury to the person (Mass. Gen. Laws ch. 106, section 2-316A(4)).

This is general information, not legal advice for a specific deal. Whether any disclaimer or remedy holds turns on the governing law and the facts; confirm against the controlling state's version of the UCC before you rely on it. For how a false factual statement (rather than a broken promise) is handled, see our guide on representations and warranties.

Review checklist

• The express warranty is vague ("high quality," "industry standard") instead of tied to a spec, the documentation, or a measurable standard.
• The disclaimer does not carve back out the express warranty you just negotiated, creating a conflict.
• The disclaimer of implied warranties is not conspicuous or omits the word "merchantability," so it may not hold.
• The survival / warranty period is short (30-90 days) relative to when defects actually surface in this product.
• The remedy is repair-only with no refund and no escape if repair fails.
• No express provision for failure of essential purpose, leaving the buyer with nothing if the seller cannot fix the defect.
• A particular-purpose reliance exists (the seller knows the buyer's specific use) but the fitness warranty is silently disclaimed anyway.
• Warranty, disclaimer, exclusive remedy, and the liability cap are read in isolation; check whether the cap and consequential-damages waiver quietly hollow out the warranty.

How it interacts with other clauses

The warranty clause never stands alone. Read it together with:

• Warranty disclaimer: the conspicuous "AS IS" language that removes the implied warranties; the express warranty must be carved back out of it.
• Representations and warranties: a representation is a statement of present fact (misrepresentation claim); a warranty is a forward promise about quality (breach-of-contract claim). Deals often blur the two.
• Limitation of liability: the cap and consequential-damages waiver can shrink warranty recovery to almost nothing, and a failed exclusive remedy can drag the cap into the fight.
• Indemnification: title and IP non-infringement warranties usually route their remedy to an indemnity, not repair-or-replace.

FAQ

What is a warranty clause? It is a contract provision stating what the product or service is guaranteed to be or do, for how long, and what the buyer gets if the promise fails. It sets out the express warranties, addresses the implied warranties (usually by disclaiming them), and defines the remedy for breach.

What is the difference between an express and an implied warranty? An express warranty is a promise the parties write into the contract (the goods conform to spec, the software performs per the documentation). An implied warranty is one the law adds automatically in a sale of goods, chiefly merchantability and fitness for a particular purpose under UCC Article 2, unless the seller disclaims it.

How do you disclaim implied warranties? With a conspicuous written disclaimer. Under the uniform text of UCC 2-316(2), to disclaim merchantability the language must mention merchantability and, in a writing, be conspicuous; to disclaim fitness it must be a conspicuous writing. Selling goods "as is" or "with all faults" removes the implied warranties in one phrase if the language calls the buyer's attention to the exclusion and makes plain there is no implied warranty (2-316(3)(a)).

What is the difference between a warranty and a representation? A representation is a statement of present or past fact that induces the other side to enter the deal; a false one supports a misrepresentation claim. A warranty is a promise that a thing is or will be as stated; a breach supports a contract claim. Many contracts state facts "as a representation and warranty" to preserve both.

What is the difference between a warranty and an indemnity? A warranty is a promise about the deliverable, breach of which lets the buyer recover its own damages (subject to the remedy and the cap). An indemnity is a promise by one party to cover another party's loss, typically from third-party claims, and usually operates outside the warranty remedy and, if negotiated, outside the liability cap.

How long should a warranty last? It depends on the product and the deal. A period of 12 months from delivery or acceptance is often proposed, buyers push for longer periods (or the useful life of the product) for durable or high-stakes goods, and sellers push for 30 to 90 days. We did not survey contracts to measure these. The warranty period is a negotiated term, not a fixed rule, and the UCC limitations period for a warranty claim is separate (see above).

What happens if the exclusive remedy fails? Under UCC 2-719(2), if an exclusive "repair or replace" remedy fails of its essential purpose because the seller cannot actually cure the defect, remedy may be had as provided in the UCC. Courts disagree on whether a separate consequential-damages exclusion survives that failure (compare Chatlos and RRX Industries), so it is worth addressing expressly in the clause.
