Discover the three main methods used to certify the safety and security of goods handed over to airlines: X-ray scanners, canine detection (K9 teams), and odorological screening. Learn how each method works and how frequently they are used.

There are three main methods for certifying the safety and security of goods handed over to airlines. They are listed from most to least frequently used:

X-Ray Scanning (80% of the time)

This method uses imaging to identify the contents of a package or pallet. The package or pallet is passed through an X-ray machine which, much like a medical X-ray, allows operators to see what is inside without opening it.

When goods cannot be scanned (dimensions too large for the scanner, opaque packaging that neutralizes the X-ray effect — such as black shrink wrap around a pallet or sealed blue plastic drums), two other methods can be used.

Canine Detection (K9 Screening)

This method is used approximately 19% of the time in France — even less in most other countries. A handler uses a specially trained dog to sniff the package or pallet. The dog is capable of detecting any explosive or narcotic substance.

Odorological Screening

This method involves sampling the air from a container, package, or pallet (i.e., testing the entire atmosphere of a truck or container) using special filters. These filters are then processed in a laboratory to be easily sniffed by a K9 team. No container opening, no unpacking or sampling — the goods remain intact. It is also worth noting that this technique allows each dog to sniff seven atmospheres at once, which significantly reduces waiting times.

Good to know: Cargo security screening can take time. Just as passengers need to arrive at the airport early to pass through security, the same applies to freight (lead times may vary from one airport to another).
