Why is UN 1120 Dangerous On An Aircraft?
UN 1120 (Butanols, II) describes liquids that catch fire easily. Packing Group II means the liquid has a low flash point, so it gives off flammable vapours at moderate temperatures. On an aircraft, this creates a serious ignition risk from heat, sparks, static electricity, or a leaking package, and a fire could start and spread quickly inside the cargo hold.
Because aircraft cargo holds have limited oxygen and rely on fire-suppression systems, fires from highly flammable liquids are much harder to control mid-flight than on the ground, and could threaten the aircraft's structure or safety systems before landing. For this reason, UN 1120 (Butanols, II) is normally heavily restricted, requiring strict packaging, quantity limits, and labelling.

Passenger & cargo aircraft statuts
Passenger aircraft carry paying passengers, with cargo in the lower hold. Passenger aircraft offer more routes, more frequent flights, and generally lower costs, but they allow smaller quantities per package.
Cargo aircraft (freighters) carry freight only, with no passengers on board. Cargo-only aircraft allow larger quantities, but they have fewer flights, longer transit times, and higher costs.
Choosing which aircraft type a shipment of UN 1120 (Butanols, II) can use is one of the first important decisions in the process.
Some dangerous goods are restricted to either passenger aircraft or cargo-only aircraft, but UN 1120 (Butanols, II) is not. It can be transported on both types of aircraft:
Passenger aircraft 💺 — PERMITTED
Cargo aircraft ✈️ — PERMITTED
"Permitted" does not mean the substance can be carried by air without restriction. It is still a dangerous good and must comply with strict packing, packaging, marking, labelling, documentation and quantity rules imposed by IATA/ICAO, as well as by individual countries and airline operators.

Packing Instructions
UN 1120 (Butanols, II) is a dangerous good and poses a risk on aircraft.
To mitigate this risk, quantities are limited, but this alone is not sufficient. Each shipment must comply with strict packing, packaging, marking, labelling, and documentation requirements.
All of these requirements are consolidated in what is called the Packing Instruction.
PASSENGER AIRCRAFT
Passenger aircraft operate flights that carry passengers. Because people are on board, the maximum quantity allowed per package is lower:
Packing instruction — PI 353
Max net quantity — 5 L
CARGO AIRCRAFT ONLY
Dedicated freighter aircraft carry no passengers. As a result, larger quantities per shipment are allowed, but these flights are less frequent and serve fewer routes:
Packing instruction — PI 364
Max net quantity — 60 L

Excepted & Limited Quantity Exemptions
Exemptions allow you to ship smaller quantities under simplified rules, with reduced packaging, marking, and documentation compared to a full shipment. They don't remove the hazard classification—only the amount of compliance work required.
LIMITED QUANTITY
Max net quantity per package — 1 L
Packing instruction — Y341
EXCEPTED QUANTITY
Max net quantity — 500 mL
Check carefully the inner packaging strict quantity limits
