Why Cargo Screening Alone Won't Stop Hidden Dangerous Goods

Klaus Schmidt · 2026-09-25

You might think that once a package goes through an X-ray machine, it's safe. But what if the real threat isn't what's visible on the screen? The International Air Transport Association (IATA) recently made a bold statement: security screening is just one layer of protection, and it can't be the only solution to the growing problem of undeclared and mis-declared dangerous goods in air cargo. ### The Problem with Relying on Screening Screening technology has come a long way, but it's not foolproof. Dangerous goods can be hidden in ways that even advanced scanners miss. For example, lithium batteries might be disguised as everyday electronics, or chemicals could be mislabeled as harmless materials. Screening alone can't catch everything, especially when the paperwork says one thing and the package contains another. That's why IATA is calling for a multi-layered approach. It's not about replacing screening; it's about adding more defenses. Think of it like securing a house: you wouldn't rely solely on a deadbolt. You'd also have locks on windows, an alarm system, and maybe a dog. Each layer makes it harder for a burglar to get in. Similarly, air cargo security needs multiple layers to be truly effective. ### What Are These Layers? A multi-layered approach means combining different strategies to reduce risk. Here are some key elements: - **Accurate documentation:** Shippers must declare exactly what's in the package. Falsifying documents should have serious consequences. - **Training and awareness:** Everyone in the supply chain, from packers to pilots, needs to recognize the signs of undeclared dangerous goods. - **Advanced screening technologies:** While not perfect, better scanners and artificial intelligence can help identify anomalies. - **Collaboration:** Regulators, airlines, freight forwarders, and shippers must work together. No single entity can solve this alone. ### Why Collaboration Is Key IATA stresses that collaboration is not just nice to have—it's essential. Regulators are currently discussing how to strengthen aviation security, and they're looking at screening as a primary defense. But IATA warns that over-relying on screening could give a false sense of security. Instead, the entire supply chain needs to share information and best practices. > "Security screening is an important layer of protection, but not a primary solution," IATA stated. This quote sums up the core message: we need more than just technology. ### The Real-World Impact Undeclared dangerous goods can lead to catastrophic incidents. A single undeclared lithium battery can cause a fire in the cargo hold, endangering lives and costing millions. In 2024 alone, there were over 50 reported incidents involving undeclared dangerous goods in air cargo. Each incident disrupts operations, damages reputations, and increases insurance costs. For professionals in the rental property industry, this might seem unrelated. But consider this: many rental properties are furnished with electronics that contain lithium batteries. If those items are shipped as cargo without proper declaration, they pose a risk. Understanding the challenges in air cargo can help you make safer choices when sourcing products for your rentals. ### What Can You Do? If you're involved in shipping or receiving goods, here's how you can contribute: - Always declare dangerous goods accurately. If you're unsure, ask. - Train your staff on how to identify and handle dangerous goods. - Choose logistics partners who prioritize safety and compliance. - Stay informed about regulations and best practices. ### The Bottom Line Screening alone won't solve the problem of undeclared dangerous goods. It's a critical tool, but it needs to be part of a broader strategy. By working together and layering our defenses, we can make air cargo safer for everyone. Whether you're shipping products for your rental properties or managing a global supply chain, remember that safety is a shared responsibility. So next time you send a package, think beyond the scanner. Ask yourself: what else can I do to ensure it's safe? The answer might just save lives.
