How Airlines Handle Cargo That Cannot Be X-Rayed

X-rayed screening is one of the most common methods used to inspect shipments before they are loaded onto an aircraft. However, not all cargo can pass through standard X-ray equipment.

Some shipments may be too large, too dense, unusually shaped, or require special handling, making standard X-ray screening unsuitable. In these situations, airlines and cargo handling teams may use alternative security procedures to determine whether the shipment can be safely cleared for air transport.

So, how do airlines handle cargo that cannot be screened by X-ray? Let’s take a closer look.

1. Why Some Cargo Cannot Be X-Rayed

Not every shipment can pass through a standard cargo X-ray machine.

Common reasons include:

The shipment is too large for the screening equipment.
The cargo is too heavy to be moved through the machine.
Its dimensions or shape prevent proper screening.
Dense materials make it difficult for the X-ray system to produce a clear image.
The shipment requires special handling and cannot easily be moved.

For example, oversized machinery, industrial equipment, or large cargo pieces may require a different security screening process.

2. Alternative Screening Methods May Be Required

When standard X-ray screening is not suitable, cargo may be subject to other approved security procedures.

Depending on the airport, cargo type, and applicable security requirements, these may include:

Physical inspection.
Explosive trace detection.
Canine screening.
Additional documentation checks.
Other approved security screening methods.

The goal is to ensure that the shipment has been properly screened before being accepted for air transportation.

3. Physical Inspection May Take More Time

One alternative is a physical inspection of the shipment.

Cargo handlers or authorized security personnel may inspect the packaging and accessible parts of the shipment according to applicable procedures.

Depending on the cargo, this process may involve:

Opening selected packaging.
Checking the contents.
Verifying the shipment description.
Inspecting for unusual or prohibited items.

Because physical inspections can require additional coordination, they may take longer than standard X-ray screening.

4. The Cargo May Need to Be Repositioned or Repacked

In some cases, a shipment may not be suitable for screening in its original form.

The cargo could require:

Repositioning on a pallet.
Separation into smaller pieces.
Repacking for safer handling.
Additional preparation before alternative screening.

However, this depends on whether the shipment can be safely handled without damaging the cargo or violating packaging requirements.

5. Documentation Becomes Even More Important

When a shipment requires additional screening, accurate documentation becomes especially important.

Airlines and handlers may need to verify information such as:

The exact description of the goods.
The shipper and consignee details.
Cargo dimensions and weight.
The nature and intended use of the goods.
Any special handling requirements.

Incorrect or incomplete information can create additional delays during the screening process.

6. Special Cargo May Require Extra Coordination

Oversized, high-value, temperature-sensitive, or other special cargo may require coordination between multiple parties.

These can include:

The shipper.
Freight forwarder.
Ground handling company.
Airline.
Airport security authorities.

Planning the screening process in advance can help avoid last-minute problems at the cargo terminal.

7. What Happens If the Cargo Cannot Be Cleared?

If a shipment cannot complete the required security procedures, it may not be accepted for the planned flight.

The cargo could be:

Held for further inspection.
Rebooked on a later flight.
Returned to the warehouse for additional preparation.
Repacked or separated for screening.
Subject to further review by the relevant authorities.

The exact outcome depends on the reason the cargo could not be cleared and the procedures available at the airport.

How Can Shippers Avoid Delays?

To reduce the risk of delays, shippers should:

Provide Accurate Cargo Information

Always provide correct details about the shipment’s contents, dimensions, weight, and handling requirements.

Plan Ahead for Oversized Cargo

If a shipment is too large or unusual for standard screening equipment, inform the freight forwarder or airline before the cargo arrives at the airport.

Prepare Complete Documentation

Ensure that all required shipping documents and cargo descriptions are accurate and consistent.

Coordinate With the Freight Forwarder

Freight forwarders can help identify potential screening requirements and arrange appropriate handling before the shipment reaches the airport.

Frequently Asked Questions

1. Can cargo that cannot be X-rayed still be transported by air?

Yes. Cargo that cannot go through standard X-ray screening may still be accepted for air transport if it successfully completes other approved security screening procedures.

2. Why is some cargo too large for X-ray screening?

Oversized machinery, industrial equipment, or unusually shaped shipments may exceed the size or weight limits of standard X-ray equipment, making alternative screening necessary.

3. Will alternative security screening delay my shipment?

It can. Physical inspections or other screening procedures may require additional time and coordination, especially if the shipment was not identified as oversized or difficult to screen in advance.

4. What should shippers do before sending cargo that cannot be X-rayed?

Shippers should provide accurate information about the cargo’s dimensions, weight, contents, and special handling requirements. It is also important to inform the freight forwarder or airline before the shipment arrives at the airport.

5. What happens if the cargo cannot pass the required security screening?

The shipment may be held for further inspection, repacked, rebooked on a later flight, or returned for additional preparation. The final outcome depends on the applicable security requirements and the nature of the cargo.

Conclusion

Cargo that cannot be X-rayed does not automatically mean that it cannot be transported by air. However, it may require alternative security screening and additional coordination before it can be cleared for loading.

The best approach is to identify potential screening challenges early. By providing accurate cargo information and planning ahead, shippers can reduce delays and help ensure that their cargo moves through the airport security process as smoothly as possible.
