When it comes to shipping goods through the air, security comes first. That’s where the Known Shipper Management System (KSMS) comes in. You can think of it like a screening process that keeps air cargo safe and makes shipping smoother for businesses.

In this article, we will explain what KSMS is, what it means to be a “known Shipper”, the benefits of this and how your business can become a known shipper.

What Is the KSMS?

The Known Shipper Management System (KSMS) is a program that the related official department employs to qualify shippers to load cargo on passenger planes.

For example, in the U.S., the Transportation Security Administration (TSA) runs the KSMS to screen and approve shippers before they can tender cargo for passenger aircraft.TSA keeps a list of trusted shippers in its records as “known shippers”.

Unknown shippers or businesses that aren’t approved can only ship via cargo-only aircraft. It helps prevent unauthorized or high-risk shippers from using passenger flights.

The known shipper program works through freight forwarders or air carriers, and they vet shippers, send the required information, and get approval for them in the trusted shipper list. Once shippers are approved, they get certain benefits and more flexibility in air freight. 

What Are the Benefits of Becoming a Known Shipper?

If your business gets approved under KSMS, it will bring a lot of good perks for your air freight business.

First, a known shipper status gives you access to more flight options. You aren’t limited to cargo-only flights; rather, you can ship your goods on passenger flights as well. Passenger planes run more frequently and have more routes, which means shipments reach their desired destination more quickly. This flexibility is especially helpful for time-sensitive shipments in industries like healthcare and e-commerce, where delays can cause serious consequences. Besides, in the U.S., TSA-approved shipments don’t go through unnecessary security checks as unknown shippers, so there are shorter delivery times.

Secondly, having a known shipper tag usually lowers cost. As there are more aircraft options, there is more competition among carriers, and more frequent flight schedules mean you have an option of comparing and negotiating prices.

Lastly, the status enhances your credibility. It shows your business follows strict security protocols. This can make you more attractive to airlines and logistics partners, leading to better business relationships and fewer delays at ports.

How to Become a Known Shipper

If you want your business to gain known shipper status through the Known Shipper Management System. In the U.S., this is how the process works:

  • Team up with a freight forwarder or Indirect Air Carrier (IAC) that already works with TSA. These partners know the TSA’s KSMS well and can help you in submitting your profile for review. 

  • Gather and provide certain documents. These documents might include your business name, address, contact details, shipping history, and some proof that you have been shipping previously. Also, TSA might require you to confirm your physical facility and security controls. 

  • Often, a site visit is also required so TSA or your freight forwarder can check that your operations meet security standards. 

  • Finally, once everything is submitted, TSA reviews the application through the Know Shipper Management System (KSMS). If the application is approved, your company will be added to the list of known shippers, and you will be given a unique known shipper ID. 

Becoming a known shipper will require some time, depending on how quickly you can provide the required information and documents. But once your application is approved, all your efforts will pay off. 

Conclusion

The Known Shipper Management System (KSMS) is all about making air cargo safer and giving trusted businesses more flexibility. By becoming a known shipper, your business can access passenger flights, save costs, and improve your delivery efficiency. This all will be achieved while enhancing your credibility in the market. 

The application process might require some paperwork and verification, but the benefits you will gain after that are worth it. As a business, if you ship goods through air, taking the step to become a known shipper can make your supply chain faster, safer, and more reliable.
