A product that is not fit for its particular purpose or that has a defect that inhibits functionality and cannot be corrected must be replaced. A product that needs to be replaced will be returned to the supplier, who is responsible for substituting for the item another item that meets the contractual requirements and is void of all defects. When return for replacement is required, the supplier is responsible for all costs of transportation and for risk of loss in transit. When the cost of physical return makes it impractical to return an item for replacement, the supplier will be responsible for removing the item from its current physical location, with Postal Service concurrence, and for disposing of the item at the supplier’s expense.
