Unlike full dangerous goods compliance, the ADR (road), IMDG Code (sea), and IATA-DGR (air) regulations grant simplified requirements for certain hazardous substances when the quantity per inner packaging stays below substance-specific thresholds. Qualifying shipments must meet defined packaging standards and display the distinctive LQ diamond mark, but are largely exempt from documentation, placarding, and vehicle requirements. Knowing the exact per-substance limit is critical for logistics teams: exceeding it by even a small margin triggers full compliance obligations immediately. Limited quantities are distinct from excepted quantities, which offer broader exemptions under even stricter conditions.
