Air Transport of Sensitive Goods: Which Categories Require Special Attention?

Air Transport of Sensitive Goods: Which Categories Require Special Attention?

In the field of international air transport, the shipment of sensitive goods remains a critical challenge for cross-border e-commerce and foreign trade enterprises. This article systematically categorizes six major classifications of sensitive goods for air transport, provides an in-depth analysis of transportation regulations for special categories such as lithium batteries, liquids, powders, magnetic materials, pharmaceuticals, and food products, and details the latest regulatory requirements from IATA, ICAO, and various national aviation authorities. It also presents a comprehensive solution for the compliant air transport of sensitive goods.

Aligned with the 2024-2025 revisions of the IATA Dangerous Goods Regulations (DGR), this guide incorporates real-world case studies to help readers master compliant operational procedures, avoid legal risks, and mitigate transportation safety hazards.

1. Overview and Regulatory Framework for Sensitive Goods Air Transport

1.1 Definition and Classification of Sensitive Goods

Sensitive cargo refers to items that, due to their physical, chemical, or biological properties, may pose risks to health, safety, property, or the environment during air transport. According to the latest IATA 2025 classification standards, sensitive goods are divided into six major categories:

1. Dangerous Goods (DG)
   • Class 1: Explosives (e.g., fireworks)
   • Class 2: Gases (e.g., aerosol cans, diving cylinders)
   • Class 3: Flammable Liquids (e.g., alcohol, paint)
   • Class 4: Flammable Solids (e.g., magnesium powder, activated carbon)
   • Class 5: Oxidizers (e.g., bleach, peroxides)
   • Class 6: Toxic Substances (e.g., pesticides, mercury compounds)
   • Class 7: Radioactive Materials
   • Class 8: Corrosives (e.g., batteries, strong acids)
   • Class 9: Miscellaneous Dangerous Goods (e.g., dry ice, lithium batteries)
2. Regulated Articles
   • Weapons, ammunition, and accessories
   • Narcotics and psychotropic substances
   • Endangered species products (CITES-listed)
   • Cultural relics and artworks
3. Special Cargo
   • Temperature-controlled goods (vaccines, biologics)
   • Live animals (pets, lab animals)
   • Valuables (gold, jewelry)
   • Human organs and remains
4. Sensitive but Non-Hazardous Goods
   • Electronics with trace liquids/gels
   • Weakly magnetic materials (speakers, motors)
   • Nanomaterials
   • Certain cosmetics and personal care products

1.2 International Regulatory System

Global air cargo regulations follow a three-tiered framework:

1. International Level
   • ICAO’s Technical Instructions for the Safe Transport of Dangerous Goods by Air (Doc 9284)
   • IATA’s Dangerous Goods Regulations (DGR) 2025 Edition
   • WCO’s Harmonized System (HS) Code Classification
2. Regional Level
   • EU: Aviation Safety Regulation (EU) No 965/2012
   • USA: DOT 49 CFR 100-185
   • China: CAAC’s Regulations on the Transport of Dangerous Goods by Air (CCAR-276)
3. Airline-Specific Policies
   • Carrier-specific restrictions (e.g., Lufthansa Cargo’s DG guidelines)
   • Variations in lithium battery transport rules

2.2.2 Packaging Rules

1. Single container ≤100mL (aerosols ≤500mL).
2. Total outer package ≤2L.
3. Leak-proof secondary containment.
4. Absorbent material (must retain full liquid volume).

2.3 Magnetic Materials

Must pass magnetic field test (<0.159 A/m at 2.1m distance).

   • Assign correct UN number & packing group.
2. Compliant Packaging
   • Use UN-certified packaging (e.g., 4GV boxes).
   • Apply triple-layer packaging (inner + cushioning + outer).
   • Include hazard labels (e.g., lithium battery marks).
3. Documentation
   • Shipper’s Declaration for Dangerous Goods.
   • Cargo Security Declaration.
