IATA is a global trade association of airlines that establishes standards and regulations for the safe, secure, and efficient transportation of passengers and cargo via air. In logistics, IATA rules govern cargo documentation, packaging, labeling, shipment of hazardous materials, and operational procedures. Compliance with IATA standards ensures that air freight shipments meet international safety requirements, avoids delays, and mitigates risks associated with transport. IATA also provides training, auditing, and certification services to maintain industry-wide best practices.
