When consumers buy goods, California law implies a basic promise: the product will meet ordinary quality and performance expectations. CACI No. 3210 explains how juries evaluate claims for breach of the implied warranty of merchantability when a consumer good fails to meet those expectations.
This instruction applies to many everyday products, from household goods and electronics to tools, equipment, and packaged consumer items.
What Is the Implied Warranty of Merchantability?
The implied warranty of merchantability means that a consumer good must be reasonably fit for its ordinary purpose, consistent with industry standards, and packaged and labeled in a way that matches what consumers are promised.
CACI No. 3210 applies when a product is not necessarily dangerous, but is defective in quality, function, or reliability compared to what a buyer reasonably expects.

CACI No. 3210. Breach of Implied Warranty of Merchantability – Essential Factual Elements
[Name of plaintiff] claims that the [consumer good] did not have the quality that a buyer would reasonably expect. This is known as “breach of an implied warranty.” To establish this claim, [name of plaintiff] must prove all of the following:
- That [name of plaintiff] bought a[n] [consumer good] [from/manufactured by] [name of defendant];
- That at the time of purchase [name of defendant] was in the business of [selling [consumer goods] to retail buyers/manufacturing [consumer goods]];
- That the [consumer good]:
- was not of the same quality as those generally acceptable in the trade; or
- was not fit for the ordinary purposes for which the goods are used; or
- was not adequately contained, packaged, and labeled; or
- did not measure up to the promises or facts stated on the container or label;
- That [name of plaintiff] was harmed; and
- That [name of defendant]’s breach of the implied warranty was a substantial factor in causing [name of plaintiff]’s harm.

How Juries Evaluate Merchantability
Under CACI 3210, jurors evaluate whether the product met ordinary consumer expectations, not whether it was the best product available. Key questions include:
- Does the product perform its basic intended function?
- Is its quality consistent with similar products sold in the marketplace?
- Was it packaged and labeled accurately and adequately?
- Did it live up to the promises made on the label or packaging?
If the product fails in any of these respects and causes harm, liability may attach.
Legal Foundation for Implied Warranty Claims
California recognizes implied warranties as part of its consumer protection framework, ensuring that sellers and manufacturers stand behind the basic quality of the goods they place into the marketplace.
Unlike negligence claims, implied warranty claims focus on the condition of the product itself, not whether the seller acted carefully.
Illustrative Example
A household appliance repeatedly fails during normal use shortly after purchase, despite being used exactly as intended. Even if it does not pose a safety hazard, a jury may find that the product breached the implied warranty of merchantability because it was not fit for its ordinary purpose.
Practical Considerations in Warranty Cases
Implied warranty claims often rely on:
- Product performance history and failure rates
- Industry standards and comparable products
- Packaging, labeling, and marketing representations
- Repair records, recalls, or consumer complaints
These cases focus on what the buyer reasonably expected versus what they received.
