A "Known Shipper" refers to a sender or shipper whose identity and shipping practices are well-documented and verified by the transportation authorities or a shipping carrier. Known Shippers have undergone a thorough vetting process to establish their legitimacy, adherence to security protocols, and compliance with shipping regulations, particularly concerning hazardous materials or restricted items.
This designation allows them to ship goods with greater ease and fewer security checks, as their status as a Known Shipper signifies a higher level of trust and reliability in their shipping practices.
