Toxic substances — dangerous goods classification
Division 6.1 substances are liable to cause death or serious injury on ingestion, inhalation or skin contact. Packing group follows the LD50 and LC50 criteria in 49 CFR 173.133.
The mistake this category generates
Toxicity often appears as a subsidiary risk on a substance classified primarily as something else — methanol is Class 3 with a 6.1 subsidiary, and needs both labels.

Shipper notes
UN1230 Methanol
- Toxic by inhalation and skin absorption, which is why the subsidiary 6.1 label is required alongside the flammable liquid label.
- Forbidden on passenger aircraft; permitted on cargo aircraft under the IATA DGR entry.
UN2809 Mercury
- Mercury contained in a manufactured article — a thermometer or a switch — ships as UN3506 instead. Mercury is forbidden on passenger aircraft because of its corrosivity to aluminium.
UN2810 Toxic liquid, organic, n.o.s.
- Packing group follows the oral, dermal and inhalation LD50/LC50 criteria in 49 CFR 173.133.
