UN 1173 (Ethyl acetate) — Air Shipping Requirements

QUICK GLANCE

UN 1173 (Ethyl acetate) is a dangerous product classified as Flammable Liquid (Class 3). It presents a medium degree of danger (Packing Group II). It can be shipped on passenger aircraft, up to 5 L net per package, and on cargo aircraft only, up to 60 L net per package — cargo aircraft allows a higher net quantity. It qualifies for the Limited Quantity exemption (up to 1 L net per package) and the Excepted Quantity exemption (up to 500 mL net per package). Specific country restrictions, airline operator restrictions, and special provisions also apply - these override the standard ICAO/IATA rules.

Why is UN 1173 Dangerous On An Aircraft?

Ethyl acetate (UN 1173) poses a fire and explosion risk aboard aircraft due to its low flash point (approximately -4°C), meaning it releases flammable vapors even at relatively low ambient temperatures.

In the confined, pressurized environment of a cargo hold, any leakage can allow vapors to accumulate rapidly, creating conditions where a spark or heat source could trigger combustion or explosion during flight.

Its high volatility compounds the risk: packaging failure results not merely in a liquid spill but in rapid vapor release. Classified as Packing Group II (medium hazard), it presents sufficient flammability and volatility to warrant strict regulatory controls on permitted quantities, packaging standards, and loading location aboard the aircraft.

Passenger & cargo aircraft statuts

Passenger aircraft carry paying passengers, with cargo in the lower hold. Cargo aircraft (freighters) carry freight only, with no passengers on board.

Choosing which aircraft type a shipment of UN 1173 can use is one of the first important decisions in the process.

Passenger aircraft offer more routes, more frequent flights, and generally lower costs, but they allow smaller quantities per package. Cargo-only aircraft allow larger quantities, but they have fewer flights, longer transit times, and higher costs.

Some dangerous goods are restricted to either passenger aircraft or cargo-only aircraft, but UN 1173 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 1173 (Ethyl acetate) 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 per package — 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 per package — 60 L
