Known Shipper

A known shipper is an entity that has been vetted and approved under the TSA’s (Transportation Security Administration) Known Shipper Program, allowing it to tender cargo for transport on passenger aircraft within or departing from the United States. This designation is a security requirement, not a service level or commercial status. Without known shipper approval, cargo must either fly on all-cargo (freighter) aircraft or undergo additional screening before it can be loaded onto a passenger plane.

Why the Known Shipper Program Exists

After the security policy changes following 2001, the TSA implemented stricter controls over cargo carried on passenger aircraft. The Known Shipper Program is part of the broader air cargo security framework designed to ensure that freight placed in the belly of passenger planes does not pose a threat. The program applies specifically to cargo tendered to indirect air carriers (IACs) and to airlines operating passenger flights.

Cargo shipped on all-cargo aircraft (such as dedicated FedEx or UPS freighter flights) is not subject to the known shipper requirement, though it must still undergo screening under the TSA’s Certified Cargo Screening Program (CCSP).

How to Become a Known Shipper

The vetting process is managed by the TSA through the Known Shipper Management System (KSMS). When a company first tenders cargo to an IAC or airline for shipment on a passenger aircraft, the carrier submits the shipper’s information to the TSA. The TSA reviews the company’s identity, business history, and other security-relevant data. Approval typically takes 24 to 72 hours for established businesses with verifiable records.

The information submitted includes the company name, physical address (P.O. boxes are not accepted), phone number, and a point of contact. The TSA cross-references this data against government databases. Companies operating from residential addresses, newly formed businesses, or entities with inconsistent records may face delays or additional scrutiny.

Once approved, the shipper’s status is recorded in the KSMS database. The approval is linked to the specific business entity and address, not to individual employees. If the company moves to a new address, the known shipper status must be re-established.

Operational Implications

For shippers who are not yet approved as known shippers, the practical impact is that their cargo must undergo physical screening (X-ray, ETD, physical search, or canine inspection) before it can be loaded onto a passenger aircraft. This adds time, cost, and handling to the shipment. Alternatively, the shipper can route their freight exclusively on all-cargo carriers, which may limit options and increase rates on certain lanes.

Freight forwarders who operate as IACs maintain their own known shipper databases. When an FBA seller or e-commerce business contacts a freight forwarder to ship goods by air, the forwarder checks whether the seller has known shipper status. If not, the forwarder initiates the vetting process. First-time air shippers should request this vetting well before their first shipment to avoid delays.

Relevance for E-commerce and FBA Sellers

Most FBA sellers ship inventory by ocean freight, making the known shipper designation less relevant for routine inventory replenishment. However, sellers who use air freight for urgent restocks, product launches, or lightweight high-value items need to understand this requirement. A seller who suddenly needs to air ship 500 units to avoid a stockout and has never shipped by air before may face a 1 to 3 day delay while the TSA completes vetting.

Sellers who anticipate periodic air shipments should establish their known shipper status proactively by working with their freight forwarder to submit the initial vetting request. There is no fee from the TSA for the vetting process itself, though the freight forwarder may include it as part of their setup or booking process.

The known shipper program does not apply to small parcel shipments sent through integrated carriers like FedEx Express or UPS, as those companies operate their own all-cargo aircraft and have separate security protocols for packages entering their networks.
