Under the International Air Transport Association Dangerous Goods Regulations (DGR), UN-specified packaging is mandatory because it has been performance-tested to withstand the stresses of air transport, including pressure changes, vibration, and handling impacts. This ensures safety and regulatory compliance.
UN-specified packaging refers to packaging that has passed internationally recognized performance tests in accordance with UN standards (IATA DGR Part 6). It bears a UN marking code that confirms the packaging type, material, packing group performance level, manufacturer, and year of manufacture.
Dangerous Goods are assigned to Packing Groups I, II, or III based on the degree of danger. UN packaging is tested and certified according to these levels, ensuring the packaging strength matches the hazard level of the material.
Dangerous Goods packing is the regulated process of preparing hazardous materials for safe transportation in accordance with international transport regulations. It includes correct classification, selection of UN-approved packaging, proper marking and labeling, and accurate documentation.
DDG packing must be carried out by trained and certified personnel who are competent under applicable regulations (e.g., GCAA&IATA CBTA requirements for air shipments).
The primary reference is the Material Safety Data Sheet (MSDS) / Safety Data Sheet (SDS). Section 14 (Transport Information) clearly states whether the product is classified as Dangerous Goods, including the UN number, Proper Shipping Name, hazard class, and packing group.
