Shipping Dangerous Goods (DG) requires strict compliance with international safety regulations. Whether it’s flammable liquids, toxic chemicals, or lithium batteries, proper handling is critical to prevent hazards.
This guide covers everything you need to know about DG classification, packaging, labeling, and safe transportation.
What Are Dangerous Goods?
Dangerous Goods (DG) are substances that pose risks to health, safety, or the environment when transported. Common types include:
- Flammable Liquids (e.g., gasoline, paint)
- Gases (e.g., propane, compressed oxygen)
- Explosives (e.g., fireworks, ammunition)
- Lithium Batteries (used in electronics, EVs)
💡 Fact: Lithium batteries have been involved in major air transport incidents, leading to strict airline restrictions.
DG Classification & Labeling

🚨 The 9 DG Hazard Classes:
Class | Category | Examples |
1️ | Explosives | Fireworks, TNT |
2️ | Gases | Oxygen tanks, propane |
3️ | Flammable Liquids | Gasoline, ethanol |
4️ | Flammable Solids | Matches, sodium |
5️ | Oxidizing Substances | Hydrogen peroxide, bleach |
6️ | Toxic & Infectious Substances | Pesticides, medical waste |
7️ | Radioactive Materials | Uranium, X-ray equipment |
8️ | Corrosives | Battery acids, ammonia |
9️ | Miscellaneous DG | Lithium batteries, dry ice |
📌 DG shipments require proper labeling with UN numbers and hazard symbols. Failure to comply can result in shipment rejection or fines.
International DG Regulations
DG transport is governed by international safety bodies:
Regulatory Body | Mode of Transport |
IATA (International Air Transport Association) | Air Freight ✈ |
IMO (International Maritime Organization – IMDG Code) | Ocean Freight 🚢 |
ADR (European Agreement on DG Transport) | Road Transport 🚛 |
ICAO (International Civil Aviation Organization) | Air Freight ✈ |
💡 Key Requirement: Each shipment must comply with packaging, labeling, and documentation rules set by these authorities.
DG Packaging & UN Certification

📦 Types of DG Packaging: ✔
- Single Packaging – Used for liquids and gases (e.g., fuel containers)
- Combination Packaging – Inner containers inside an outer box for added safety
- Intermediate Bulk Containers (IBC) – Used for large DG shipments
All DG packaging must be UN-certified and pass strict safety tests.
📌 Example UN Packaging Code: 👉 UN 4G/Y25/S/24 USA/M4567
- 4G – Type of container (Fiberboard Box)
- Y25 – Performance rating
- S – Solid contents
- 24 – Year of manufacture
- USA – Country of approval
- M4567 – Manufacturer’s code
DG Documentation Requirements
Essential DG Shipping Documents:
- Shipper’s Declaration for DG (DGD) – Confirms compliance with safety rules
- Material Safety Data Sheet (MSDS) – Details on DG hazards & handling
- UN Certification for Packaging – Ensures regulatory compliance
- Transport Emergency Card (TREM Card) – Used for emergency response
🚨 Missing documentation? Your shipment could be delayed or rejected!
Best Practices for Safe DG Handling
✅ Train Employees – DG handlers must be certified in safety procedures
✅ Use AI & Automation – AI-driven tracking systems ensure compliance
✅ Follow Regulatory Guidelines – Stay updated on IATA, IMO, and UN rules
✅ Conduct Regular Safety Audits – Inspections reduce compliance risks
✅ Have an Emergency Plan – Preparedness prevents accidents and losses
💡 Did You Know? Lithium battery fires can reach over 1000°C, making them a serious hazard for air cargo transport!
The Future of DG Logistics
🚀 Trends Shaping DG Logistics:
- AI-Powered DG Classification – Automates hazard identification
- Blockchain-Based Tracking – Secures real-time supply chain transparency
- Sustainable DG Packaging – Reducing environmental impact
With digitalization and AI-driven logistics, DG handling is becoming safer, more efficient, and fully compliant with global standards.
Conclusion
Shipping Dangerous Goods is complex, requiring expert knowledge, compliance with global regulations, and precision in handling. Whether you’re transporting flammable liquids, lithium batteries, or hazardous chemicals, following proper DG classification, labeling, packaging, and documentation is crucial.
