DGR Class 9 — Miscellaneous

DGR Class 9 — Miscellaneous is a dangerous goods classification for any substances and articles which during transport present a danger or hazard not covered by other dangerous goods classes. This class encompasses miscellaneous dangerous substances and articles, including environmentally hazardous substances. Common Class 9 materials include lithium batteries, asbestos, dry ice, and magnetized materials. Miscellaneous dangerous substances and articles may be in UN Packing Group II or III, or have no Packing Group.

A FedEx Express shipment with AWB number 023-12345678 carries lithium ion batteries classified as UN3480, requiring Class 9 labels and specific packing instructions per IATA DGR. An Emirates SkyCargo flight AWB 176-87654321 transports dry ice (UN1845) from Dubai International Airport to John F. Kennedy International Airport, with the cargo requiring ventilation markings and net weight declarations due to its sublimation properties.

What are the most common DGR Class 9 — Miscellaneous dangerous goods shipped by air?

The three most commonly shipped Class 9 dangerous goods are flammable liquids, dry ice, and lithium batteries. Dry ice has a temperature of -79°C, magnetized materials require field strength measurements at 2.1 meters (maximum 0.418 A/m), and lithium batteries have state-of-charge limits of less than 30% for cargo air transport.

What specific field strength limit applies to magnetized materials in DGR Class 9?

The DGR specifies regulations for any magnetized material that has a maximum magnetic field strength sufficient to cause a compass deflection of more than 2 degrees at a distance of 2.1 meters from any point on the surface of the assembled package. That magnetic field strength is equal to 0.418 A/m. Magnets with relatively high magnetic field strength can interfere with the instruments onboard the aircraft.
