An implied warranty of fitness arises under the Uniform Commercial Code §2-315 when a buyer requests something for a particular purpose, and the seller then supplies a product for that purpose.
For example, if a farmer goes to a farm supply store, and tells the salesperson they need a plow for the rocky soil of their farm, and the salesperson directs them to a particular plow, there may be an implied warranty that the plow in question is fit for use in rocky soil.
In the event that the product subject to the implied warranty of fitness is unsatisfactory for the buyer’s expressed purpose, the seller may be liable for breach of warranty and subject to damages.
