Merchantability: Most importantly, a merchant in goods of a particular type is held to automatically warrant that they are “merchantable” (i.e., “fit for the ordinary purposes for which such goods are used”).

Fitness for particular purpose: Also, a seller may be found to implicitly warrant that the goods are “fit for a particular purpose” — this warranty arises where the seller knows that the buyer wants the goods for a particular purpose, and the buyer relies on the seller’s recommendation of a suitable product.
