The Known Consignor Scheme

Information for cargo companies

The Known Consignor scheme is voluntary. There is no legal requirement for any air cargo to be despatched from the shipper as SPX (Secure) cargo; insecure cargo may still be shipped, although it will be subject to additional security measures before it can be allowed to fly.

However, once approved as a Known Consignor, you must comply with the requirements outlined in the Regulations.

Once approved, Known Consignors are permitted to ship cargo from source. Such cargo may be transported by air without the need for any further security measures being applied.


  • HR presence at the site inspection to provide details of the recruitment procedures for all staff including a pre-employment check or a criminal background check.

You must be able to demonstrate that:

  • all staff (permanent, temporary or agency staff and drivers) with access to air cargo / mail have received the appropriate aviation security training
  • access to the production area is controlled and the production process is supervised.

Details of approved cargo trainers are available on our website.
