Under Article 2 of the Uniform Commercial Code, when a buyer rejects a seller's tender of goods because it is not a perfect tender, the seller may have an option to cure if the time for performance has not expired. For example, if the seller did not have a perfect tender of a delivery of goods sent to a buyer, such as sending less of a certain item than the buyer requested, if it is prior to a date set by the parties that was to be the latest date for delivery, the seller will have an opportunity to remedy the error.
