Warranty disclaimer: what it means and how to draft it

What a warranty disclaimer does

Every sale of goods carries promises the parties never typed out. Under the Uniform Commercial Code (UCC), a merchant who sells goods impliedly warrants that they are merchantable, meaning fit for the ordinary purpose for which such goods are used (UCC 2-314). When the seller has reason to know the buyer is relying on the seller’s skill to select goods for a particular purpose, an implied warranty of fitness for that purpose can also arise (UCC 2-315). A warranty disclaimer is how a seller opts out of these default promises, in whole or in part.

The clause does three things at once. It identifies which warranties are being excluded, most often the implied warranties of merchantability and fitness. It preserves any express warranty the parties actually intend to give, so the disclaimer does not accidentally swallow the promise the deal is built on. And it shifts the risk of quality and performance onto the buyer for everything outside that narrow express commitment. A well-drafted disclaimer is not a refusal to stand behind anything; it is a deliberate line between what the seller guarantees and what the buyer accepts as-is.

Because the clause reallocates risk that the law would otherwise place on the seller, courts read it strictly. The language has to hit statutory markers, and it has to be visible. Miss either requirement and the disclaimer is treated as if it were never written.

Drafting example

The sample below combines an express-warranty carve-out with a conspicuous exclusion of implied warranties and an as-is allocation of risk. Adapt the section references and the scope of the express warranty; keep the structure and the conspicuous formatting.

Warranties; Disclaimer. Except for the limited express warranty stated in Section [X], the Goods are provided “AS IS” and “WITH ALL FAULTS.” 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, USAGE OF TRADE, OR COURSE OF PERFORMANCE. Buyer assumes all risk as to the quality and performance of the Goods except as expressly warranted in Section [X].

Read the clause part by part. The opening carve-out (“Except for the limited express warranty stated in Section [X]”) tells the reader that one promise survives and points to exactly where it lives, so the disclaimer and the express warranty do not contradict each other. The words “AS IS” and “WITH ALL FAULTS” invoke a recognized shorthand that, on its own, excludes implied warranties under the UCC. The capitalized sentence does the technical work: it names “merchantability” by that word, refers to fitness for a particular purpose, and sweeps in warranties that arise from prior dealings or trade custom. The final sentence states the practical consequence, that the buyer carries the risk of quality outside the express promise, which is the point a court will look to when the goods disappoint.

The formatting is not decoration. The exclusion is set in capital letters and bold precisely because the statute requires the disclaimer to be conspicuous, a requirement examined below.

What the law says

Implied warranties are the default, and the disclaimer is the exception. UCC 2-314 and 2-315 create the implied warranties of merchantability and fitness automatically in qualifying sales of goods. A disclaimer only removes what the statute lets it remove, and only in the manner the statute prescribes.

The exclusion has to meet UCC 2-316. To exclude or modify the implied warranty of merchantability, the language must mention the word “merchantability,” and if the disclaimer is in writing it must be conspicuous. To exclude the implied warranty of fitness, the exclusion must be in writing and conspicuous, though it can be stated in general terms, such as a statement that there are no warranties extending beyond the description of the goods. Separately, UCC 2-316(3)(a) recognizes that expressions like “as is” or “with all faults,” in common understanding, call the buyer’s attention to the exclusion and make plain that there is no implied warranty.

Conspicuous has a defined meaning. Under UCC 1-201(b)(10), a term is conspicuous when it is written so that a reasonable person against whom it operates ought to have noticed it, for example headings in capitals, or body text in larger type, contrasting color, or bold. This is why disclaimers are so often in all caps: burying the exclusion in ordinary type invites a court to strike it.

Express warranties are hard to erase. UCC 2-313 provides that affirmations of fact, descriptions, samples, and models can create express warranties. UCC 2-316(1) instructs courts to read express warranties and disclaimers as consistent where reasonable, and to disregard the disclaimer to the extent the two cannot be reconciled. In practice, a seller cannot make a specific promise and then negate it with boilerplate; the promise usually wins.

Consumer sales carry extra limits. The federal Magnuson-Moss Warranty Act restricts a supplier that gives a written warranty on a consumer product, or sells a service contract, from disclaiming or modifying the implied warranties on that product. Several states also restrict or forbid as-is sales and implied-warranty disclaimers in consumer transactions, so a clause that is valid business-to-business may be unenforceable against a consumer.

Software and services do not map cleanly onto Article 2. The UCC governs goods, and whether it reaches software licenses or mixed goods-and-services deals varies by jurisdiction and by how the contract is characterized. Even so, as-is and no-implied-warranty language is standard in software and SaaS terms, and the drafting instincts (name the warranties, be conspicuous, preserve the intended express warranty) carry over.

Common mistakes to avoid

Forgetting to name “merchantability.” UCC 2-316 is explicit: a disclaimer of merchantability must use that word. A clause that broadly says “no warranties of any kind” without naming merchantability may fail to exclude it.

Hiding the disclaimer in ordinary type. An exclusion in the same small font as the rest of the terms is not conspicuous and can be disregarded. Capitals, bold, or contrasting type are the cheap insurance that keeps the clause alive.

Contradicting an express warranty. Promising specific performance or a service level in one section and disclaiming “all warranties” in another creates a conflict that UCC 2-316(1) resolves against the disclaimer. Carve out the express warranty by cross-reference so the two provisions read as one plan.

Using a business-to-business disclaimer against consumers. As-is language that works between merchants can be void in a consumer sale under Magnuson-Moss or state law. A disclaimer needs to match the counterparty.

Confusing a warranty disclaimer with a limitation of liability. A disclaimer controls what is promised; a limitation-of-liability or damages cap controls what the buyer can recover if a surviving promise is broken. They are complementary clauses, not substitutes, and a strong contract uses both deliberately.

When it matters most

Warranty disclaimers earn their place wherever a product or service may not perform to a buyer’s private expectations and the seller wants a clear, defensible boundary. They are central to sales of equipment and components, to as-is sales of used or clearance inventory, to software and SaaS terms of service, and to any deal where an implied warranty of fitness could otherwise attach because the buyer described a purpose and leaned on the seller’s judgment. The higher the risk that goods could be blamed for a downstream failure, the more the exact wording and the conspicuous formatting matter.

A disclaimer is also a negotiation lever. Buyers push to preserve implied warranties or to win a robust express warranty; sellers push toward as-is. Where the line lands, and how the surviving express warranty is scoped, often decides who absorbs the cost when something goes wrong.

None of this protects you if the clause is inconsistent from one contract to the next. A warranty disclaimer only works when it is present, conspicuous, and aligned with the express warranties and liability caps around it, across an entire portfolio rather than in one carefully drafted template. This is where disciplined contract management pays off: a repository that surfaces every agreement’s warranty terms, standardized templates that carry conspicuous disclaimer language by default, and a copilot that helps reviewers spot a missing disclaimer or a conflict between an express warranty and a disclaimer before signature. Pactolane’s CLM platform and its PactAI copilot are built for exactly that kind of consistency, so the boundary you drafted once is the boundary that actually holds every time you sign.
