The Known Consignor (KC) program is voluntary. The Known Consignor process allows companies to declare their cargo as suitable to be considered as ‘secure’ air cargo, providing they abide by the rules, regulation and good practise provided by the Department for Transport and the Civil Aviation Authority.

There are many different sectors that are active Known Consignors and all work to the same principles. A site will manufacture or source their own products and identify them as air cargo at site. The job of the Known Consignor, once air cargo is identified, is to pick/ pack, secure, store and dispatch in a safe and secure manner. When this is achieved the Known Consignor can send their cargo as suitable to be considered as ‘secure’, which negates the need for further screening at a Cargo Regulated Agent premises.

The Civil Aviation Authority (CAA) are the regulators in this process and do provide some support with initial queries regarding the suitability of sites and whether the Known Consignor process is right for their company. There is a list of Aviation Security Consultants who can provide more information and guidance on your journey to becoming a Known Consignor.

Part of the initial process is to recruit and train your staff to the required level as all employees involved are new to the Known Consignor process. You will also be sent Known Consignor material to help you to better understand the process.

We will endeavour to support you with guidance (on this page) and advice when required:

  • security program
  • guide to becoming a Known Consignor in the UK
  • aviation recruitment guide

Details of approved cargo trainers (to be used to verify the status of a cargo trainer).

Every Known Consignor is subject to a 12 monthly validation of their premises. This involves a site visit by a CAA Aviation Security Compliance Auditor who will review your secure process and your recruitment and training of AvSec staff only. Existing Known Consignors are subject to yearly validation audits, these are normally within 2 months of the expiry date but may on some occasions be earlier than this. The validation date does not affect your expiry date.

A guide to applications for Known Consignors is available from the CAA by using the contact details on this page.
