Box overrun refers to the excess amount of products or items that are produced or ordered beyond the intended quantity, resulting in an overflow of boxes. This can occur due to miscommunication, miscalculation, or unexpected demand. The term is commonly used in manufacturing and retail industries, where the production or ordering of goods is done in bulk. Box overrun can lead to storage and logistical challenges, as well as potential financial losses if the excess items cannot be sold or utilized.
