Lesson 38

Understanding Warranties in Sales Contracts

Recommended resources

Hello! Welcome back to our course.

In our last lesson, we drew a clear line between contracts governed by common law and those governed by the Uniform Commercial Code (UCC). You learned that the UCC brings a more flexible, commercially-minded set of rules to contracts for the sale of goods.

Today, we dive into one of the most critical aspects of UCC Article 2: warranties. Warranties are essentially promises made by a seller about the quality, condition, or performance of the goods being sold. For a corporate lawyer, understanding warranties is fundamental. You will encounter them constantly when drafting sales agreements, advising on product liability risks, or conducting due diligence in a merger where you must assess the selling company's contractual obligations.

Our goal for this lesson is to evaluate warranties in sales contracts, including express and implied warranties. We'll explore how these promises are created—sometimes intentionally, sometimes automatically by law—and, just as importantly, how they can be limited or removed.

1. Two Worlds of Warranty: Express and Implied

At its core, a warranty provides a buyer with a legal recourse if the goods don't live up to the seller's promises. The UCC organizes these promises into two main categories:

  1. Express Warranties: These are explicit promises made by the seller through words, descriptions, or samples.
  2. Implied Warranties: These are unstated promises that are automatically imposed by the law on the seller to ensure a basic level of quality and fitness.
Implied Warranty vs. Express Warranty
This image visually contrasts the two main categories of warranties. Express warranties are explicitly stated, while implied warranties are automatically included by law unless properly disclaimed.

Let's start by examining the warranties that sellers create themselves.


2. Express Warranties: What the Seller Affirms

An express warranty is created when a seller makes a factual claim about the goods that becomes part of the buyer's reason for making the purchase (the "basis of the bargain"). Importantly, the seller doesn't need to use formal words like "warrant" or "guarantee" to create one.

Under UCC § 2-313, an express warranty can be created in three ways:

  • An affirmation of fact or a promise: "This engine will produce 200 horsepower."
  • A description of the goods: "Laptop with a 16-inch Retina display."
  • A sample or model: Showing a floor model of a sofa to a customer.

This seems straightforward, but it raises a key legal question: where is the line between a binding, factual promise and mere sales talk?

Distinguishing Warranty from "Puffery"

The law allows for a certain amount of "puffing"—subjective, opinion-based statements that a reasonable person would not take as a literal guarantee. A statement like "This is the best-looking car on the lot" is puffery. A statement like "This car has a V8 engine and has never been in an accident" is an affirmation of fact that creates an express warranty.

The more specific, measurable, and factual a statement is, the more likely it is to be an express warranty. The following reading provides an excellent overview and includes some classic legal cases that illustrate this distinction.

9.2: Warranties

Let's read 'Types of Warranties' from the resource 'Warranties' by LibreTexts. This will clarify how express warranties are created and the crucial difference between a binding warranty and non-binding 'puffery'.

Please read the subsection titled 'Express Warranties'. Pay close attention to the three ways an express warranty is created and the examples of the 'defective used car' and the 'faulty bull' to understand the fine line between fact and opinion.

Test your understanding!

A salesperson at an art supply store is selling a set of professional-grade paintbrushes to a customer. The salesperson makes the following statements:

  1. "These are fantastic brushes; you'll love them."
  2. "These brushes are made with 100% natural kolinsky sable hair."
  3. "These brushes will not shed any bristles for at least two years of regular use."
  4. "In my opinion, this is the best value in the whole store."

Which of these statements create an express warranty?

Show answer
  • Statement 2 ("100% natural kolinsky sable hair") creates an express warranty. This is a specific, verifiable description of the goods.
  • Statement 3 ("will not shed... for at least two years") creates an express warranty. This is a specific promise about the future performance of the goods.

Statements 1 and 4 are likely considered puffery. They are subjective opinions about the product's quality ("fantastic") and value ("best value"), not objective facts.


3. Implied Warranties: The Promises Built into the Sale

Unlike express warranties, implied warranties are not explicitly stated by the seller. They are created by the UCC itself to establish a baseline of quality that buyers can expect. These are often at the heart of product liability disputes. There are two major types you must know.

The Implied Warranty of Merchantability

This is the most common and important implied warranty. Under UCC § 2-314, when a merchant who regularly sells a certain type of good sells it, they automatically warrant that the good is "merchantable."

So, what does "merchantable" mean? It means the goods are reasonably fit for their ordinary purpose. A refrigerator must keep food cold, a raincoat must be waterproof, and a phone must be able to make calls.

This warranty only applies to sellers who are merchants for those goods. If you sell your used car to a neighbor, you are not a merchant, and this warranty does not apply. If a car dealership sells a used car, it does.

The Implied Warranty of Fitness for a Particular Purpose

This warranty is more specific. Under UCC § 2-315, it arises when any seller (not just a merchant) has reason to know two things at the time of the sale:

  1. The buyer has a particular purpose for the goods (i.e., a non-ordinary purpose).
  2. The buyer is relying on the seller's skill and judgment to select suitable goods.

The key distinction here is between "ordinary" and "particular" purpose. The ordinary purpose of hiking boots is to be worn for hiking on trails. If you tell a shoe salesperson you need boots for a sub-zero arctic expedition and they recommend a specific pair based on your request, an implied warranty of fitness for that particular purpose is created.

To deepen your understanding of these crucial concepts, let's turn back to our reading.

9.2: Warranties

The sections on 'Implied Warranties' and 'Other Warranties' from LibreTexts explain the key types of implied warranties in detail. Nolo's article also provides very clear examples.

First, read the subsection 'Implied Warranties'. Focus on the six characteristics of merchantability and the clear distinction between 'ordinary purpose' (merchantability) and 'particular purpose' (fitness). Then, briefly read 'Other Warranties' to understand the warranty of title, using the Chagall painting case as a mental hook. For more simple, direct examples, you can also consult the Nolo article 'The UCC and Sales Contract Warranties' (LINK), under the headings 'Implied Warranty of Merchantability' and 'Implied Warranty of Fitness for a Particular Purpose'.


4. Disclaimers: Taking Warranties Away

Now for the part of the contract that a corporate lawyer scrutinizes very carefully. Sellers often want to limit their liability, and the UCC allows them to disclaim or modify warranties, but they must follow specific rules to do so effectively.

  • Excluding Express Warranties: This is difficult. If a seller makes an explicit promise, a court is reluctant to enforce fine print that takes it away. The best way for a seller to avoid an express warranty is not to make one in the first place.

  • Excluding Implied Warranties: This is more common.

    • Sellers can use "magic words" like "as is", "with all faults", or similar language that makes it plain to the buyer that there are no implied warranties.
    • To disclaim the warranty of merchantability specifically, the disclaimer must mention the word "merchantability." If the disclaimer is in writing, it must be conspicuous (e.g., in bold, capital letters, or a different color).
    • To disclaim the warranty of fitness for a particular purpose, the disclaimer must be in writing and be conspicuous. General language is sufficient (e.g., "THERE ARE NO WARRANTIES WHICH EXTEND BEYOND THE DESCRIPTION ON THE FACE HEREOF.").

A Federal Limit: The Magnuson-Moss Warranty Act

The ability to disclaim warranties led to a practice of offering "phantom warranties," where a seller would offer a very limited express warranty in big print while disclaiming the more valuable implied warranties in fine print.

To combat this for consumers, Congress passed the Magnuson-Moss Warranty Act. Its most important rule for our purposes is this: if a seller provides a written warranty for a consumer product, they cannot disclaim the implied warranties. They can, however, limit the duration of implied warranties to the duration of the express warranty (e.g., a "1-Year Limited Warranty"). This act is a great example of how federal law can overlay state law (the UCC).

Let's read about how these disclaimers and limitations work in practice.

9.2: Warranties

The final reading explains the rules for disclaiming warranties and the important limitations placed on sellers by the Magnuson-Moss Act.

Please read the sections on 'Exclusion or Modification of Warranties' and 'The Magnuson-Moss Act and Phantom Warranties'. Pay close attention to the specific language required to disclaim implied warranties and the crucial rule that prohibits disclaiming implied warranties when a written warranty is given for a consumer product.


Conclusion

You have now explored the full life cycle of warranties under the UCC—from their creation to their disclaimer. Understanding this framework is not just an academic exercise; it's a practical skill for protecting a client's interests, whether they are a buyer seeking assurances or a seller managing risk.

Key Takeaways:

  • Express warranties are created by a seller's factual affirmations, descriptions, or samples. They must be distinguished from subjective "puffery."
  • The implied warranty of merchantability is an automatic promise from a merchant that the goods are fit for their ordinary purpose.
  • The implied warranty of fitness for a particular purpose arises when a buyer relies on the seller's expertise to select goods for a specific, non-ordinary use.
  • Sellers can disclaim implied warranties using conspicuous language like "as is" or by specifically mentioning "merchantability," but federal law limits this ability in consumer transactions.

In our next lesson, we will examine what happens when a seller fails to live up to these warranties. We will explore the perfect tender rule, a strict UCC standard of performance, and compare it to the more lenient doctrine of substantial performance that we briefly touched on in the common law context.
