§ 172.203

Additional description re-



Special permits. Except as provided 

in § 173.23 of this subchapter, each ship-
ping paper issued in connection with a 
shipment made under a special permit 
must bear the notation ‘‘DOT–SP’’ fol-
lowed by the special permit number as-
signed and located so that the notation 
is clearly associated with the descrip-
tion to which the special permit ap-
plies. Each shipping paper issued in 
connection with a shipment made 
under an exemption or special permit 
issued prior to October 1, 2007, may 
bear the notation ‘‘DOT–E’’ followed by 
the number assigned and so located 
that the notation is clearly associated 
with the description to which it ap-


Limited quantities. When a ship-

ping paper is required by this sub-
chapter, the description for a material 
offered for transportation as ‘‘limited 
quantity,’’ as authorized by this sub-
chapter, must include the words ‘‘Lim-
ited Quantity’’ or ‘‘Ltd Qty’’ following 
the basic description. 


Hazardous substances. (1) Except 

for Class 7 (radioactive) materials de-
scribed in accordance with paragraph 
(d) of this section, if the proper ship-
ping name for a material that is a haz-
ardous substance does not identify the 
hazardous substance by name, the 
name of the hazardous substance must 
be entered in parentheses in associa-
tion with the basic description. If the 
material contains two or more haz-
ardous substances, at least two haz-
ardous substances, including the two 
with the lowest reportable quantities 
(RQs), must be identified. For a haz-
ardous waste, the waste code (e.g., 
D001), if appropriate, may be used to 
identify the hazardous substance. 

(2) The letters ‘‘RQ’’ must be entered 

on the shipping paper either before or 
after the basic description required by 
§ 172.202 for each hazardous substance 
(see definition in § 171.8 of this sub-
chapter). For example: ‘‘RQ, UN 1098, 
Allyl alcohol, 6.1, I, Toxic-inhalation 
hazard, Zone B’’; or ‘‘UN 3077, Environ-
mentally hazardous substances, solid, 
n.o.s., 9, III, RQ (Adipic acid)’’. 


Radioactive material. The descrip-

tion for a shipment of a Class 7 (radio-
active) material must include the fol-

lowing additional entries as appro-

(1) The name of each radionuclide in 

the Class 7 (radioactive) material that 
is listed in § 173.435 of this subchapter. 
For mixtures of radionuclides, the 
radionuclides required to be shown 
must be determined in accordance with 
§ 173.433(g) of this subchapter. Abbre-

e.g., ‘‘


Mo,’’ are authorized. 

(2) A description of the physical and 

chemical form of the material: 

(i) For special form materials, the 

words ‘‘special form’’ unless the words 
‘‘special form’’ already appear in the 
proper shipping name; or 

(ii) If the material is not in special 

form, a description of the physical and 
chemical form of the material (generic 
chemical descriptions are permitted). 

(3) The maximum activity of the ra-

dioactive contents contained in each 
package during transport in terms of 
the appropriate SI units (


Becquerels (Bq), Terabecquerels (TBq)). 
The activity may also be stated in ap-
propriate customary units (

e.g.,  Curies 

(Ci), milliCuries (mCi), microCuries 
(uCi)) in parentheses following the SI 
units. Abbreviations are authorized. 
Except for plutonium-239 and pluto-
nium-241, the weight in grams or kilo-
grams of fissile radionuclides (or the 
mass of each fissile nuclide for mix-
tures when appropriate) may be in-
serted 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 in-
serted in addition to the activity units. 

(4) The category of label applied to 

each package in the shipment. For ex-
ample: ‘‘RADIOACTIVE WHITE–I,’’ or 

(5) The transport index assigned to 

each package in the shipment bearing 

(6) For a package containing fissile 

Class 7 (radioactive) material: 

(i) The words ‘‘Fissile Excepted’’ if 

the package is excepted pursuant to 
§ 173.453 of this subchapter; or other-

(ii) The criticality safety index for 

that package.

(j) [Reserved] 

Technical names for ‘‘n.o.s.’’ and 

other generic descriptions. Unless other-
wise excepted, if a material is de-
scribed on a shipping paper by one of 
the proper shipping names identified by 
the letter ‘‘G’’ in column (1) of the 
§ 172.101 Table, the technical name of 
the hazardous material must be en-
tered in parentheses in association 
with the basic description. For example 
‘‘UN 1760, Corrosive liquid, n.o.s., (Oc-
tanoyl chloride), 8, II’’, or ‘‘UN 1760, 
Corrosive liquid, n.o.s., 8, II (contains 
Octanoyl chloride)’’. The word ‘‘con-
tains’’ may be used in association with 
the technical name, if appropriate. For 
organic peroxides which may qualify 
for more than one generic listing de-
pending on concentration, the tech-
nical name must include the actual 
concentration being shipped or the con-
centration range for the appropriate 
generic listing. For example, ‘‘UN 3102, 
Organic peroxide type B, solid, 5.2, 
(dibenzoyl peroxide, 52–100%)’’ or ‘‘UN 
3108, Organic peroxide type E, solid, 5.2, 
(dibenzoyl peroxide, paste, <52%)’’. 
Shipping descriptions for toxic mate-
rials that meet the criteria of Division 
6.1, PG I or II (as specified in § 173.132(a) 
of this subchapter) or Division 2.3 (as 
specified in § 173.115(c) of this sub-
chapter) and are identified by the let-
ter ‘‘G’’ in column (1) of the § 172.101 
Table, must have the technical name of 
the toxic constituent entered in paren-
theses in association with the basic de-
scription. A material classed as Divi-
sion 6.2 and assigned identification 
number UN 2814 or UN 2900 that is sus-
pected to contain an unknown Cat-

egory A infectious substance must 
have the words ‘‘suspected Category A 
infectious substance’’ entered in paren-
theses in place of the technical name 
as part of the proper shipping descrip-
tion. For additional technical name op-
tions, see the definition for ‘‘Technical 
name’’ in § 171.8. A technical name 
should not be marked on the outer 
package of a Division 6.2 material (see 
§ 172.301(b)). 

(1) If a hazardous material is a mix-

ture or solution of two or more haz-
ardous materials, the technical names 
of at least two components most pre-
dominately contributing to the hazards 
of the mixture or solution must be en-
tered on the shipping paper as required 
by paragraph (k) of this section. For 
example, ‘‘UN 2924, Flammable liquid, 
corrosive, n.o.s., 3 (8), II (contains 
Methanol, Potassium hydroxide)’’. 

(2) The provisions of this paragraph 

do not apply— 

(i) To a material that is a hazardous 

waste and described using the proper 
shipping name ‘‘Hazardous waste, liq-

or  solid, n.o.s.’’, classed as a mis-

cellaneous Class 9, provided the EPA 
hazardous waste number is included on 
the shipping paper in association with 
the basic description, or provided the 
material is described in accordance 
with the provisions of § 172.203(c) of this 

(ii) To a material for which the haz-

ard class is to be determined by testing 
under the criteria in § 172.101(c)(11). 

(iii) If the n.o.s. description for the 

material (other than a mixture of haz-
ardous materials of different classes 
meeting the definitions of more than 
one hazard class) contains the name of 
the chemical element or group which is 
primarily responsible for the material 
being included in the hazard class indi-

(iv) If the n.o.s. description for the 

material (which is a mixture of haz-
ardous materials of different classes 
meeting the definition of more than 
one hazard class) contains the name of 
the chemical element or group respon-
sible for the material meeting the defi-
nition of one of these classes. In such 
cases, only the technical name of the 
component that is not appropriately 
identified in the n.o.s. description shall 
be entered in parentheses.

§ 172.204 


Marine pollutants. (1) If the proper 

shipping name for a material which is 
a marine pollutant does not identify by 
name the component which makes the 
material a marine pollutant, the name 
of that component must appear in pa-
rentheses in association with the basic 
description. Where two or more compo-
nents which make a material a marine 
pollutant are present, the names of at 
least two of the components most pre-
dominantly contributing to the marine 
pollutant designation must appear in 
parentheses in association with the 
basic description. 

(2) The words ‘‘Marine Pollutant’’ 

shall be entered in association with the 
basic description for a material which 
is a marine pollutant. 

(3) Except for transportation by ves-

sel, marine pollutants subject to the 
provisions of 49 CFR 130.11 are excepted 
from the requirements of paragraph (l) 
of this section if a phrase indicating 
the material is an oil is placed in asso-
ciation with the basic description. 

(4) Except when all or part of trans-

portation is by vessel, marine pollut-
ants in non-bulk packagings are not 
subject to the requirements of para-
graphs (l)(1) and (l)(2) of this section 
(see § 171.4 of this subchapter). 


Poisonous Materials. Notwith-

standing the hazard class to which a 
material is assigned, for materials that 
are poisonous by inhalation (see § 171.8 
of this subchapter), the words ‘‘Poison- 
Inhalation Hazard’’ or ‘‘Toxic-Inhala-
tion Hazard’’ and the words ‘‘Zone A’’, 
‘‘Zone B’’, ‘‘Zone C’’, or ‘‘Zone D’’ for 
gases or ‘‘Zone A’’ or ‘‘Zone B’’ for liq-
uids, as appropriate, shall be entered 
on the shipping paper immediately fol-
lowing the shipping description. The 
word ‘‘Poison’’ or ‘‘Toxic’’ need not be 
repeated if it otherwise appears in the 
shipping description. 


Elevated temperature materials. If a 

liquid material in a package meets the 
definition of an elevated temperature 
material in § 171.8 of this subchapter, 
and the fact that it is an elevated tem-
perature material is not disclosed in 
the proper shipping name (for example, 
when the words ‘‘Molten’’ or ‘‘Elevated 
temperature’’ are part of the proper 
shipping name), the word ‘‘HOT’’ must 
immediately precede the proper ship-

ping name of the material on the ship-
ping paper. 


Organic peroxides and self-reactive 

materials. The description on a shipping 
paper for a Division 4.1 (self-reactive) 
material or a Division 5.2 (organic per-
oxide) material must include the fol-
lowing additional information, as ap-

(1) If notification or competent au-

thority approval is required, the ship-
ping paper must contain a statement of 
approval of the classification and con-
ditions of transport. 

(2) For Division 4.1 (self-reactive) and 

Division 5.2 (organic peroxide) mate-
rials that require temperature control 
during transport, the control and emer-
gency temperature must be included on 
the shipping paper. 

(3) The word ‘‘SAMPLE’’ must be in-

cluded in association with the basic de-
scription when a sample of a Division 
4.1 (self-reactive) material (see 
§ 173.224(c)(3) of this subchapter) or Di-
vision 5.2 (organic peroxide) material 
(see § 173.225(b)(2) of this subchapter) is 
offered for transportation. 


Liquefied petroleum gas (LPG). The 

word ‘‘non-odorized’’ or ‘‘not-odorized’’ 
must be included in association with 
the proper shipping description on a 
shipping paper when non-odorized liq-
uefied petroleum gas is offered for
