For airfreight customers, the Known Shipper designation is a regulatory requirement that directly impacts your shipping overhead and transit speed. Established by the TSA, this status verifies your business as a secure entity, allowing your cargo to move on both passenger aircraft and all-cargo freighters.

The Financial Advantage of "Known" Status

Operating as an "Unknown Shipper" creates logistical bottlenecks that lead to higher invoices. Here is how gaining Known Shipper status adds value to your supply chain:

Access to Belly Cargo Rates:Passenger airlines move a massive percentage of global freight in the "belly" of scheduled flights. These carriers often offer more competitive rates than dedicated integrators (like FedEx or UPS) to fill available space. Only Known Shippers can access this pricing.
Reduced Screening Surcharges: Unknown cargo requires more intensive, time-consuming security protocols. Many Indirect Air Carriers (IACs) pass these labor and equipment costs back to the customer via "Security Handling" or "Unknown Shipper" surcharges.
Avoidance of Expedited Premiums: Because Unknown Shippers are restricted to cargo-only aircraft - which run on less frequent schedules - you may be forced to pay "Priority" premiums to secure a spot on a limited number of freighter flights. Known Shippers avoid this by utilizing the high frequency of passenger networks.

Direct Impact on Airfreight Rates: Real-World Examples

Scenario	Known Shipper	Unknown Shipper
Route Options	Can use any of the 15+ daily passenger flights between hubs.	Restricted to 1–2 dedicated nightly freighter flights.
Base Rate	Standard Market Rate: ~$2.50/kg (utilizing excess passenger capacity).	Premium Rate: ~$4.00/kg (limited freighter space availability).
Security Fees	Standard X-ray/ETD screening included in terminal fees.	Surcharge: Additional $0.15–$0.30 per kg for mandatory "Unknown" screening.
Lead Time	Same-day or Next-day departure.	48–72 hour delay waiting for available freighter space.

How to Secure Your Status

You cannot apply directly to the TSA. Your Freight Forwarder or Indirect Air Carrier (IAC) must sponsor your application. They will verify your business address, tax ID, and operational history. Once you are entered into the Known Shipper Management System (KSMS), your status is recognized across all airlines. If you are shipping more than once per quarter, the administrative effort to become a Known Shipper typically pays for itself within the first two shipments through lower base rates and avoided surcharges.
