The bonded zone is strategically positioned for "bonded warehousing, export processing, and re-export trade" as its three main functions. It offers services such as import/export processing, trade, and bonded warehousing product display, and enjoys policies of "duty-free, tax-free, and bonded storage." It operates under the "transit trade" model, making it one of China's most open economic zones with convenient operational mechanisms and preferential policies.

Perimeter fences around bonded zones are typically transparent, also known as bonded zone storage fences, comprehensive fences, bonded port area protective nets, and open storage area perimeter fences, among various names.
