Why Air Cargo Security Matters for Every Shipper
Air cargo security regulations affect every shipment that flies — whether it is a 1 kg document package or a 5,000 kg pallet of machinery. These regulations determine how your cargo is screened, what documentation you need, and how quickly your shipment can be processed at the airport. Understanding the requirements helps you avoid delays, reduce costs, and ensure your cargo moves smoothly through the supply chain.
Since 2010, aviation security authorities worldwide have progressively tightened cargo screening requirements. Today, 100% of cargo loaded on passenger aircraft must be screened, and the vast majority of freighter cargo undergoes similar screening. The rules are enforced by national aviation authorities (the TSA in the United States, the Civil Aviation Authority in the UK, EASA across the EU) under the framework set by the International Civil Aviation Organization (ICAO).
How Air Cargo Screening Works
X-Ray and Physical Inspection
Most air cargo passes through large-format X-ray machines at origin airports. These machines can scan pallets and containers without breaking them down, though unusual or suspect items may require physical inspection. X-ray screening typically adds 1–4 hours to cargo processing time at the airport.
For cargo that cannot be effectively screened by X-ray (dense materials, certain electronics, oversized items), airlines use alternative methods including explosive trace detection (ETD), physical search, and sniffer dogs. These methods take longer and may add 2–8 hours to processing time.
Known Shipper and Regulated Agent Programs
The most effective way to speed up cargo processing is to become a Known Shipper (US) or Known Consignor (EU). These programs allow pre-approved shippers to have their cargo accepted with reduced screening requirements, because the shipper’s premises and security procedures have been validated by authorities.
In the EU, the Known Consignor (KC) status is granted by national aviation authorities after an on-site security audit. KC-certified shippers can declare cargo as "secure" from origin, meaning it can be loaded on passenger aircraft with reduced screening at the airport. The certification process takes 4–8 weeks and requires demonstrating adequate premises security (access control, CCTV, background checks for staff).
In the US, the Certified Cargo Screening Program (CCSP) allows approved facilities to screen cargo before it reaches the airport. The CCSP works through the Indirect Air Carrier (IAC) program, where freight forwarders and shippers obtain TSA certification.
Regulated Agent Chain of Custody
Between the shipper and the aircraft, cargo must maintain an unbroken chain of custody through Regulated Agents (EU term) or Indirect Air Carriers (US term). Each entity in the chain is certified and audited by aviation authorities. If the chain is broken — for example, cargo is stored at a non-regulated facility — it must be re-screened before loading.
For shippers, this means choosing freight forwarders and ground handlers with proper certifications. Using non-regulated intermediaries can result in additional screening, delays, and costs. Ask your freight forwarder about their Regulated Agent status before booking.
Documentation Requirements
Shipper’s Security Declaration (SSD)
For EU shipments, shippers who are not Known Consignors must complete a Shipper’s Security Declaration for each consignment. This document declares the contents of the shipment and confirms it has been protected from unauthorized interference since packing. Your freight forwarder will provide the SSD template — it must be signed before cargo is accepted.
Dangerous Goods Declaration
If your shipment contains any dangerous goods (batteries, chemicals, compressed gases, magnetized materials, flammable items), a Dangerous Goods Declaration (DGD) must be completed by a trained and certified DG shipper. IATA’s Dangerous Goods Regulations (DGR) classify materials into 9 hazard classes, each with specific packaging, labeling, and documentation requirements.
Common items that require DG classification include: lithium batteries (in or with equipment), perfumes and cosmetics (flammable liquids), paint and adhesives, aerosol cans, dry ice (used for temperature control), and certain chemical compounds. Undeclared dangerous goods are a serious safety violation with severe penalties.
Air Waybill Security Information
The Air Waybill (AWB) must include security status information indicating the screening method applied and whether the shipment has been cleared for loading on passenger aircraft, cargo-only aircraft, or both. This information is added by the Regulated Agent or airline and follows IATA standard codes.
Special Cargo Security Considerations
Lithium Batteries
Lithium battery shipments face the strictest security and compliance requirements in air cargo. Depending on battery type (lithium-ion vs. lithium-metal), quantity, and whether batteries are packed with or in equipment, different packaging, labeling, and shipping restrictions apply. Some battery configurations are prohibited on passenger aircraft entirely and can only fly on freighter aircraft or under special approvals.
Major cargo airlines including FedEx Express, UPS Airlines, and DHL Aviation have their own additional battery shipping policies that may be stricter than IATA minimum requirements.
Perishable and Temperature-Controlled Cargo
Pharmaceutical and perishable shipments must comply with security screening while maintaining temperature integrity. X-ray screening does not affect most pharmaceuticals, but physical inspection (opening packaging) can break the cold chain. Pre-clearance through Known Consignor programs is particularly valuable for these shipments.
Valuable and High-Security Cargo
Shipments of high value (jewelry, precious metals, banknotes, electronics) or sensitive nature (diplomatic mail, military components) may require enhanced security handling. Airlines offer secure handling services with restricted access, additional documentation, and chain-of-custody tracking. These services carry premium surcharges but provide additional protection and accountability.
Compliance Tips for Shippers
Know your cargo: The most common compliance violation is inaccurate cargo description. Declare contents accurately and completely on all documentation. "General cargo" or "miscellaneous goods" descriptions are increasingly rejected by airlines and screening facilities.
Check for hidden DG: Many everyday items contain dangerous goods components. Electronics with lithium batteries, automotive parts with magnetized components, cleaning products with flammable solvents — these all require proper DG declaration even if the item itself seems ordinary.
Train your staff: If you ship regularly, invest in security awareness training for warehouse and shipping staff. IATA offers standardized training programs, and many freight forwarders provide free basic training to regular customers.
Secure your premises: Even if you are not pursuing Known Consignor certification, basic premises security (locked loading docks, visitor logs, CCTV) demonstrates due diligence and can speed up cargo acceptance.
Allow extra time: Build security screening time into your supply chain planning. Standard screening adds 2–6 hours at origin airport. If your cargo requires additional inspection, it could take 12–24 hours. For time-critical shipments, pre-arrange screening with your freight forwarder.

Frequently Asked Questions
Do all air freight shipments need to be screened?
Yes. Since the implementation of 100% cargo screening requirements (fully enforced from 2013 in the US and progressively in the EU), all cargo loaded on aircraft must be screened using an approved method. The screening method varies — Known Consignor cargo may undergo simplified checks, while unknown shipper cargo requires full X-ray or physical inspection. Cargo on freighter-only aircraft may have slightly different screening protocols than cargo on passenger aircraft, but screening is mandatory for all.
How long does air cargo security screening take?
Standard X-ray screening at origin airport takes 1–4 hours from cargo acceptance to clearance. If additional screening is required (physical inspection, ETD), add 2–8 hours. Known Consignor/Known Shipper cargo with pre-clearance can sometimes clear in under 1 hour. During peak periods or at congested airports like London Heathrow or Frankfurt, screening queues can extend processing to 6–12 hours. Always build screening time into your delivery schedule.
What happens if my cargo fails security screening?
If cargo is flagged during screening, it will undergo additional inspection methods. If the contents cannot be verified as safe, the shipment will be held and the shipper or freight forwarder will be contacted for additional information or physical inspection. In rare cases, cargo may be confiscated if undeclared dangerous goods or prohibited items are found. Repeated compliance violations can result in the shipper being flagged for enhanced screening on all future shipments, significantly increasing processing time and costs.
