exclusive use provisions; see 
173.441(b) of this subchapter). 

1

Any package containing a ‘‘highway route controlled quantity’’ (§ 173.403 of this subchapter) must be labelled as RADIO-

ACTIVE YELLOW-III. 

2

If the measured TI is not greater than 0.05, the value may be considered to be zero. 

(d) 

EMPTY label. 

See § 173.428(e) of 

this subchapter for EMPTY labeling re-
quirements. 

(e) 

FISSILE label. 

For packages re-

quired in § 172.402 to bear a FISSILE 
label, each such label must be com-
pleted with the criticality safety index 
(CSI) assigned in the NRC or DOE 
package design approval, or in the cer-
tificate of approval for special arrange-
ment or the certificate of approval for 
the package design issued by the Com-
petent Authority for import and export 
shipments. For overpacks and freight 
containers required in § 172.402 to bear 
a FISSILE label, the CSI on the label 
must be the sum of the CSIs for all of 
the packages contained in the over-
pack or freight container. 

(f) Each package required by this sec-

tion to be labeled with a RADIO-
ACTIVE label must have two of these 
labels, affixed to opposite sides of the 
package. (See § 172.406(e)(3) for freight 
container label requirements). 

(g) The following applicable items of 

information must be entered in the 
blank spaces on the RADIOACTIVE 
label by legible printing (manual or 
mechanical), using a durable weather 
resistant means of marking: 

(1) 

Contents. 

Except for LSA-1 mate-

rial, the names of the radionuclides as 
taken from the listing of radionuclides 
in § 173.435 of this subchapter (symbols 
which conform to established radiation 
protection terminology are authorized, 

i.e.

, 

99

Mo, 

60

Co, etc.). For mixtures of 

radionuclides, with consideration of 
space available on the label, the radio-
nuclides that must be shown must be 
determined in accordance with 
§ 173.433(g) of this subchapter. For LSA- 
I material, the term ‘‘LSA-I’’ may be 

used in place of the names of the radio-
nuclides. 

(2) 

Activity. 

The maximum activity of 

the radioactive contents in the pack-
age during transport must be expressed 
in appropriate SI units (

e.g., 

Becquerels 

(Bq), Terabecquerels (TBq)). The activ-
ity may also be stated in appropriate 
customary units (

e.g., 

Curies (Ci), 

milliCuries (mCi), microCuries (uCi)) 
in parentheses following the SI units. 
Abbreviations are authorized. Except 
for plutonium-239 and plutonium-241, 
the weight in grams or kilograms of 
fissile radionuclides (or the mass of 
each fissile nuclide for mixtures when 
appropriate) may be inserted instead of 
activity units. For plutonium-239 and 
plutonium-241, the weight in grams of 
fissile radionuclides (or the mass of 
each fissile nuclide for mixtures when 
appropriate) may be inserted in addi-
tion to the activity units. 

(3) 

Transport index. 

(see § 173.403 of 

this subchapter.) 

(h) When one or more packages of 

Class 7 (radioactive) material are 
placed within an overpack, the over-
pack must be labeled as prescribed in 
this section, except as follows: 

(1) The ‘‘contents’’ entry on the label 

may state ‘‘mixed’’ in place of the 
names of the radionuclides unless each 
inside package contains the same 
radionuclide(s). 

(2) The ‘‘activity’’ entry on the label 

must be determined by adding together 
the number of becquerels of the Class 7 
(radioactive) materials packages con-
tained therein. 

(3) For an overpack, the transport 

index (TI) must be determined by add-
ing together the transport indices of 
the Class 7 (radioactive) materials
