Which organization regulates the air transport of dangerous goods such as these samples?

• A. IATA
• B. ICAO
• C. DOT
• D. IMO

Answer: (A)

Air dangerous goods are governed in practice by the rules airlines and shippers actually use, which come from IATA. The IATA Dangerous Goods Regulations provide the detailed requirements for classification, packaging, labeling, documentation, and handling of dangerous goods in air transport, and these rules are harmonized with ICAO’s international standards. So, for shipments like these samples, IATA is the reference you’d follow in day-to-day air shipping. (ICAO sets the global standards, but the industry-wide, enforceable rules used by carriers are published in the IATA DGR; DOT covers U.S. domestic regulation, and IMO handles maritime transport.)
