The use of the term "whitelist" in the import field mainly refers to the catalog of cross-border e-commerce imported goods registered in the customs system. This catalog includes products that can enjoy preferential policies such as tariff reductions and faster customs clearance. Enterprises entering this catalog also need to meet certain conditions, such as compliant operations and qualified product quality. Therefore, when imported goods are queried in the customs system and belong to the whitelist, the whitelist will be displayed.
