A more thorough explanation:

Definition: “Merchantable” means that goods are of reasonable quality within expected variations and are fit for sale in the usual course of trade, at the usual selling price. Merchantable goods need not be outstanding or superior quality, they need only be fit for the ordinary purpose for which they are used.

For example, if you buy a new phone, it should be merchantable, meaning it should work properly and be fit for sale at the usual selling price. However, if you buy a used phone that is sold "as is" or "with all faults," it may not be merchantable.

There exists an implied warranty of merchantability for all items sold, unless there is some sort of disclaimer with language stipulating the item is being sold “as is” or “with all faults.” This is not to be confused with the similar but distinct implied warranty of fitness, which exists to ensure that an item requested for a particular purpose by a buyer and supplied by the seller is usable for that purpose.

Under UCC Section 2-314, for goods to be merchantable, they must be at least such as:

• Pass without objection in the trade under the contract description
• In the case of fungible goods, are of fair average quality within the description
• Are fit for the ordinary purposes for which such goods are used
• Run, within the variations permitted by the agreement, of an even kind, quality within each unit and among all units involved
• Are adequately contained, packaged and labeled as the agreement may require
• Conform to the promise or affirmations of fact made on the container or label if any

Overall, merchantable goods are those that are fit for sale and meet certain quality standards. This ensures that consumers are getting what they paid for and that the goods are suitable for their intended use.
