A pallet serves as a medium for transforming static cargo into dynamic cargo; it is a load-bearing platform-specifically, a mobile platform or a movable surface. Goods that would otherwise lack mobility when resting directly on the ground gain immediate mobility once loaded onto a pallet, becoming flexible, fluid cargo, as they are constantly poised for movement. This method of dynamic loading and unloading, utilizing the pallet as the fundamental tool, is known as pallet handling.
The Chinese national standard *Logistics Terminology* defines a pallet as a horizontal platform device used for unitizing, stacking, handling, and transporting goods and products as unit loads. As a type of unit-load equipment similar to the shipping container, the pallet is now widely used in production, transportation, warehousing, and distribution, and is regarded as one of the two key innovations in the logistics industry during the 20th century.
