Drums of Liquid Dangerous Goods for Airfreight

Drums of Liquid Dangerous Goods for Airfreight

A frequent issue with liquid dangerous goods in UN specification drums are the drums themselves. By ground transportation requirements under CFR49 removable head drums can be acceptable. When transported by air packaging instructions may require that the drums be of a non-removable head design.


Removable Head Drums

1A2 Steel drum

These are some examples but not an all inclusive list:

1A2- removable head steel drums

1H2- removable head plastic drums

3H2- removable head plastic jerricans

3A2- removable head steel jerricans

3B2- removable head aluminium jerricans

6HA2- plastic receptacle with outer steel crate*/or box

6HB2- plastic receptacle with outer aluminium crate*/or box










Non-removable Head Drums

3H1 Plastic jerricans

These are some examples but not an all inclusive list:

1A1- non-removable head steel drums

1H1- non-removable head plastic drums

3H1- non-removable head plastic jerricans

3A1- non-removable head steel jerricans

3B1- non-removable head aluminium jerricans

6HA1- plastic receptacle with outer steel drum

6HB1- plastic receptacle with outer aluminium drum




The issue with removable head drums that are single packages (meaning the dangerous goods are poured directly into the drum) is that sometimes the packaging instruction requires for the drum to be of a non-removable head design. See below for an example of Packing Instruction 364. This would be used for a packing group II flammable liquid prepared according to cargo aircraft only.



If you notice at the bottom of the Packing Instruction under "Single Packagings" that the UN codes listed are ONLY for non-removable head packages.



In this situation the material would need to be transferred to one of the authorized packages that is list in the packaging instructions.
