and stored (or kept) in a cool and well-ven-
tilated place, away from all sources of 
heat. 

47

Mixtures of solids that are not subject to 

this subchapter and flammable liquids may 
be transported under this entry without 
first applying the classification criteria of 
Division 4.1, provided there is no free liquid 
visible at the time the material is loaded 
or at the time the packaging or transport 
unit is closed. Except when the liquids are 
fully absorbed in solid material contained 
in sealed bags, for single packagings, each 
packaging must correspond to a design 
type that has passed a leakproofness test 
at the Packing Group II level. Small inner 
packagings consisting of sealed packets 
and articles containing less than 10 mL of 
a Class 3 liquid in Packing Group II or III 
absorbed onto a solid material are not sub-
ject to this subchapter provided there is no 
free liquid in the packet or article. 

48

Mixtures of solids that are not subject to 

this subchapter and toxic liquids may be 
transported under this entry without first 
applying the classification criteria of Divi-
sion 6.1, provided there is no free liquid 
visible at the time the material is loaded 
or at the time the packaging or transport 
unit is closed. For single packagings, each 
packaging must correspond to a design 
type that has passed a leakproofness test 
at the Packing Group II level. This entry 
may not be used for solids containing a 
Packing Group I liquid. 

49

Mixtures of solids that are not subject to 

this subchapter and corrosive liquids may 
be transported under this entry without 
first applying the classification criteria of 
Class 8, provided there is no free liquid 
visible at the time the material is loaded 
or at the time the packaging or transport 
unit is closed. For single packagings, each 
packaging must correspond to a design 
type that has passed a leakproofness test 
at the Packing Group II level.

Cases, cartridge, empty with primer 

which are made of metallic or plastic cas-
ings and meeting the classification criteria 
of Division 1.4 are not regulated for domes-
tic transportation. 

51

This description applies to items pre-

viously described as ‘‘Toy propellant de-
vices, Class C’’ and includes reloadable 
kits. Model rocket motors containing 30 
grams or less propellant are classed as Di-
vision 1.4S and items containing more than 
30 grams of propellant but not more than 
62.5 grams of propellant are classed as Di-
vision 1.4C. 

52 This entry may only be used for sub-

stances that are too insensitive for accept-
ance into Class 1 (explosive) when tested in 
accordance with Test Series 2 in the UN 
Manual of Tests and Criteria, Part I (incor-

porated by reference; see § 171.7 of this sub-
chapter). 

53

Packages of these materials must bear 

the subsidiary risk label, ‘‘EXPLOSIVE’’, 
and the subsidiary hazard class/division 
must be entered in parentheses imme-
diately following the primary hazard class 
in the shipping description, unless other-
wise provided in this subchapter or 
through an approval issued by the Asso-
ciate Administrator, or the competent au-
thority of the country of origin. A copy of 
the approval shall accompany the shipping 
papers. 

54

Maneb or maneb preparations not meet-

ing the definition of Division 4.3 or any 
other hazard class are not subject to the 
requirements of this subchapter when 
transported by motor vehicle, rail car, or 
aircraft. 

55

This device must be approved in accord-

ance with § 173.56 of this subchapter by the 
Associate Administrator. 

56

A means to interrupt and prevent deto-

nation of the detonator from initiating the 
detonating cord must be installed between 
each electric detonator and the detonating 
cord ends of the jet perforating guns before 
the charged jet perforating guns are of-
fered for transportation. 

57

Maneb 

or 

Maneb preparations stabilized 

against self-heating need not be classified 
in Division 4.2 when it can be dem-
onstrated by testing that a volume of 1 m

3

 

of substance does not self-ignite and that 
the temperature at the center of the sam-
ple does not exceed 200 

°

C, when the sample 

is maintained at a temperature of not less 
than 75 

°

C 

±

2 

°

C for a period of 24 hours, in 

accordance with procedures set forth for 
testing self-heating materials in the UN 
Manual of Tests and Criteria (IBR, see 
§ 171.7 of this subchapter). 

58

Aqueous solutions of Division 5.1 inor-

ganic solid nitrate substances are consid-
ered as not meeting the criteria of Division 
5.1 if the concentration of the substances 
in solution at the minimum temperature 
encountered in transport is not greater 
than 80% of the saturation limit. 

59

Ferrocerium, stabilized against corro-

sion, with a minimum iron content of 10 
percent is not subject to the requirements 
of this subchapter.
