Customs officers use a variety of tools to identify contraband cargo at ports. Here are some of them:

1. X-Ray Scanners: These are large machines that can scan entire shipping containers. They provide images of the contents, allowing officers to see if there are any hidden compartments or items that don't match the manifest.

2. Canine Units: Trained dogs are used to sniff out drugs, explosives, and other contraband. They are especially useful for checking luggage and vehicles.

3. Handheld Devices: These include density meters and ion mobility spectrometers. Density meters can detect hidden compartments in walls or floors of containers, while ion mobility spectrometers can identify traces of drugs or explosives.

4. Physical Inspection: This is the most traditional method. Officers open up the cargo and manually inspect the contents. This is usually done if there is a suspicion of contraband based on the other tools.

5. Documentation: Officers also check the paperwork of the cargo. Any discrepancies between the manifest and the actual contents can be a sign of contraband.

6. Risk Assessment Software: This software uses data analysis to identify shipments that are high risk. Factors can include the origin and destination of the shipment, the type of cargo, and the shipping company.

7. Radiation Detection Devices: These are used to detect radioactive materials. They are especially important for preventing the smuggling of nuclear materials.

These tools are used in combination to ensure that contraband is detected and seized.
