up to a limit of 100kg net mass per pack-

b. Lithium ion batteries, UN 3480, packages 

containing a single aircraft battery with 
a net mass not exceeding 35kg; and 

c. Transport in accordance with this spe-

cial provision must be noted on the ship-
ping paper. 


Refrigerating machines and refrig-

erating machine components are not sub-
ject to the requirements of this subchapter

identical package filled with water must 
show that the maximum temperature 
measured inside the packages during test-
ing does not differ by more than 200

mit the slow escape of gas (


not more 

than 0.1 mL/hour per 30 mL inner pack-
aging at 20 


C (68 


F) produced from grad-

ual decomposition. The requirements of 
§§ 173.24(g)(1) and 173.27(c) do not apply. 

A61 a. When used for purposes such as steri-

lization, inner packagings of peroxyacetic

ganic peroxide type F, liquid may be fitted 
with a vent consisting of hydrophobic 
membrane, provided: 

(1) Each inner packaging contains not 

more than 70 mL; 

(2) The inner packaging is designed so that 

the vent is not immersed in liquid in any 

(3) Each inner packaging is enclosed in an 

intermediate rigid plastic packaging 
with a small opening to permit release of 
gas and contains a buffer that neutral-
izes the contents of the inner packaging 
in the event of leakage; 

(4) Intermediate packagings are packed in 

a fiberboard box (4G) outer packaging; 

(5) Each outer packaging contains not 

more than 1.4 L of liquid; and 

(6) The rate of oxygen release from the 

outer packaging does not exceed 15 mL 
per hour. 

b. Such packages must be transported on 

cargo aircraft only. The requirements of 
§§ 173.24(g)(1) and 173.27(c) do not apply.

metal in the batteries contained in any 
piece of equipment must not exceed 12 g 
per cell and 500 g per battery. 


The total net quantity of dangerous 

goods contained in one package, excluding 
magnetic material, must not exceed the 
a. 1 kg (2.2 pounds) in the case of solids; 
b. 0.5 L (0.1 gallons) in the case of liquids; 
c. 0.5 kg (1.1 pounds) in the case of Division 

2.2 gases; or 

d. any combination thereof.

b. Rigid plastics: 11H1, 11H2, 21H1 and 21H2 
c. Composite with plastic inner receptacle: 

11HZ1, 11HZ2, 21HZ1 and 21HZ2 

d. Fiberboard: 11G 
e. Wooden: 11C, 11D and 11F (with inner lin-


f. Flexible: 13H2, 13H3, 13H4, 13H5, 13L2, 

13L3, 13L4, 13M1 and 13M2 (flexible IBCs
