Implied warranties are unspoken, unwritten promises, created by state law, that go from the seller or merchant to the customers. The Uniform Commercial Code provides for two basic types of implied warranties that occur in consumer product transactions. They are the implied warranty of merchantability and the implied warranty of fitness for a particular purpose. The "implied warranty of merchantability" is a seller's basic promise that the goods sold will do what they are supposed to do and that there is nothing significantly wrong with them. In other words, it is an implied promise that the goods are fit to be sold. According to the law, merchants make this promise automatically every time they sell a product they are in business to sell. By contrast, the implied warranty of "fitness for a particular purpose" is a promise that a seller makes when the customer relies on the advice that a product can be used for some specific purpose.
A disclaimer is a means of denying that you are making one or more express or implied warranties. In the absence of a disclaimer, a breach of warranty will often give the purchaser of the faulty item the right to recover the cost of the item as well as additional damages caused by that breach of warranty.
A product may be accompanied by instructions or warnings, instructions and warnings, or neither. The duty to warn includes the duty to provide adequate instructions for safe use. Thus, the duty to warn actually consists of two duties: (1) to provide adequate instructions for safe use, and (2) to provide a warning as to dangers inherent in improper use.
