Dangerous Goods by Air | IATA DGR & ICAO Compliance Guide |

1. What Are Dangerous Goods?

According to IATA DGR, dangerous goods (also known as hazardous materials or DG) are articles or substances which, when transported by air, are capable of posing a significant risk to health, safety, property, or the environment. These materials require specific handling, packaging, documentation, and training to ensure safe transport.

Examples of common dangerous goods shipped by air include lithium batteries (in electronics), paints and adhesives (flammable liquids), medical oxygen cylinders (gases), dry ice (used as a refrigerant), perfumes and aerosols, and industrial chemicals. Understanding classification is the first step toward compliance — and toward a charter booking that clears customs and ramp handling without delay.

2. Regulatory Framework – ICAO & IATA

Two primary documents govern dangerous goods by air:

• ICAO Technical Instructions for the Safe Transport of Dangerous Goods by Air: the international baseline standard adopted by all ICAO member states, legally binding under the Chicago Convention.
• IATA Dangerous Goods Regulations (DGR): incorporates the ICAO Technical Instructions with additional, stricter airline-specific requirements. The practical guide used by shippers, forwarders, and carriers worldwide, updated annually.

National aviation authorities — the FAA in the US, EASA in Europe, the DGCA in India, and the GCAA in the UAE, among others — enforce these regulations and may impose additional restrictions. Operators must also comply with their own Operations Specifications (OpSpecs) approved by their national authority, which is one reason an experienced charter broker with multi-jurisdiction operating experience matters for cross-border DG movements.

3. The 9 Classes of Dangerous Goods

IATA DGR divides dangerous goods into 9 hazard classes. Each class has distinct risks and handling requirements:

Important note: many substances have multiple hazards and are assigned a primary and subsidiary hazard class. Lithium batteries (Class 9) are currently the most scrutinized DG category due to fire risk.

4. Packaging Requirements & UN Specifications

Dangerous goods must be packaged in UN-certified packaging that has passed rigorous performance tests. Under IATA DGR Section 6, packaging must:

• Bear UN specification markings (e.g. “1A1/Y1.4/150/22/USA/M1234”)
• Be chemically compatible with the hazardous material
• Meet performance standards for stacking, vibration, drop, and pressure tests
• Include appropriate inner packaging and absorbent or cushioning material
• Be closed according to the manufacturer's specifications

5. Marking, Labeling & Documentation

Every dangerous goods shipment requires three layers of communication:

Marking (on the package)

• UN number (e.g. UN3480 for lithium ion batteries)
• Proper shipping name (e.g. “Lithium ion batteries”)
• Shipper and consignee name and address
• Net quantity per package
• “Overpack” marking, if applicable

Labeling (hazard communication)

• Primary hazard label (diamond, 100×100mm, colour-coded by class)
• Subsidiary hazard label, if applicable
• Cargo Aircraft Only label, for items forbidden on passenger aircraft
• Lithium battery handling label, for cells and batteries

Documentation

• Shipper's Declaration for Dangerous Goods (DGD): the IATA form certifying the shipment complies with regulations, signed by trained personnel.
• Air Waybill (AWB): includes a “Dangerous Goods” notation and indicates if the shipment is “Cargo Aircraft Only.”
• Packing List: detailed contents with DG information.

6. Lithium Batteries – Special Restrictions

Lithium batteries (rechargeable ion and non-rechargeable metal) are classified as Class 9 dangerous goods and are subject to the strictest current regulations, due to thermal-runaway fire risk:

7. Training Requirements for Shippers & Handlers

IATA DGR Section 1.5 mandates dangerous goods training for all personnel involved in preparing, offering, accepting, or handling dangerous goods shipments. Key requirements:

• Initial training: complete before performing any DG function.
• Recurrent training: every 24 months minimum — many organisations require annual refreshers.
• Function-specific training: shippers, packers, loaders, and acceptance staff each have distinct requirements.
• Documentation: training records must be retained, typically for 36 months after employment ends.
• Certification: an IATA DGR certificate is issued on completion, valid for 24 months.

Safe Fly Aviation maintains IATA-certified dangerous goods specialists on staff for all cargo charter operations, and can also advise shippers on their own compliance requirements.

Frequently Asked Questions

What are dangerous goods by air?

Dangerous goods are articles or substances which, when transported by air, are capable of posing a risk to health, safety, property, or the environment. Examples include lithium batteries, flammable liquids, gases, corrosives, explosives, and infectious substances.

What regulations govern dangerous goods by air?

The two primary regulations are the ICAO Technical Instructions for the Safe Transport of Dangerous Goods by Air (the global standard) and the IATA Dangerous Goods Regulations (DGR), which incorporate ICAO rules with additional airline-specific requirements.

What are the 9 classes of dangerous goods?

Class 1: Explosives, Class 2: Gases, Class 3: Flammable Liquids, Class 4: Flammable Solids, Class 5: Oxidizers, Class 6: Toxic & Infectious, Class 7: Radioactive, Class 8: Corrosives, Class 9: Miscellaneous (including lithium batteries and dry ice).

Can I ship lithium batteries by air?

Yes, but with strict restrictions. Lithium ion batteries (UN3480) are prohibited as cargo on passenger aircraft. They may be shipped on cargo aircraft with specific packaging, marking, and documentation requirements under IATA DGR Section IA or IB. Small batteries contained in equipment have fewer restrictions.

What training is required to ship dangerous goods by air?

IATA requires dangerous goods training every 24 months for all personnel involved in preparing, offering, accepting, or handling dangerous goods. Training must be certified and documented, and recurrent training ensures compliance with regulation updates.
