Dangerous Goods Quantity Limitations: Per Package and Per Aircraft IATA Guide

Understanding Dangerous Goods Quantity Limitations

Quantity limitations are among the most critical regulatory controls in IATA DGR dangerous goods air transport. These limits restrict how much hazmat can be placed in a single package, how much can be loaded on an aircraft, and how different hazard classes interact when co-loaded. Exceeding quantity limits is a serious violation that can ground aircraft and trigger enforcement action.

Inner Container Quantity Limits

Each packing instruction specifies maximum inner container quantities for the applicable UN numbers. These limits vary by packing group, container type (glass, plastic, metal), and whether the shipment is on passenger or cargo aircraft. PG I materials typically have the smallest inner container allowances, while PG III materials have the most generous limits. Understanding these limits drives packaging design decisions.

Package Quantity Limits

Total net quantity per package is restricted by packing instruction and aircraft type. Passenger aircraft package limits are significantly more restrictive than cargo aircraft limits. Some hazard classes are entirely forbidden on passenger aircraft. Air freight planners must calculate total package quantities against applicable limits before completing documentation and tendering shipments for acceptance.

Per Aircraft Quantity Limits

Beyond per-package limits, IATA DGR Table 7.3.A specifies maximum quantities per aircraft for certain hazard classes. These limits prevent concentration of dangerous goods that could overwhelm aircraft safety systems in an incident. When multiple hazmat shipments are booked on the same flight, cumulative quantities must not exceed per-aircraft maximums, requiring coordination between logistics providers and airlines.

Compatibility and Co-Loading Restrictions

IATA DGR Table 9.3.A governs which hazard classes may be loaded together on the same aircraft. Incompatible combinations are either forbidden or require specific separation distances. Freight forwarders shipping multiple hazmat consignments must verify compatibility before consolidating shipments for the same flight.

Limited and Excepted Quantity Benefits

Limited quantity and excepted quantity provisions offer relaxed quantity limits and simplified compliance for qualifying small shipments. These provisions enable e-commerce and sample distribution of consumer-sized hazmat products without the full regulatory burden of standard dangerous goods shipments. Maximizing LQ and EQ utilization reduces shipping costs and processing time.
