To safely manage the transport and storage of hazardous materials, you must adhere to several sets of international and regional standards. As of 2026, the primary global reference for air transport is the of the IATA Dangerous Goods Regulations (DGR) . 1. Classification & Identification
The physical containment of dangerous goods is critical. Most regulations follow a "Triple Packaging" philosophy, especially for infectious substances or liquids:
Transportation of Dangerous Goods (TDG) - Overview (Road) - CCOHS
Common exceptions include:
– DGR changes yearly (e.g., new lithium battery rules, updated packing instructions).
: Indicates the level of danger:
Packaging must be "UN Certified." This means they have undergone rigorous drop tests, stack tests, and vibration tests. A box carrying dangerous goods will usually have a UN specification mark (a code stamped on the bottom) indicating it meets these standards.
