Subpart A—General 

§ 172.1

Purpose and scope. 

This part lists and classifies those 

materials which the Department has 
designated as hazardous materials for 
purposes of transportation and pre-
scribes the requirements for shipping 
papers, package marking, labeling, and 
transport vehicle placarding applicable 
to the shipment and transportation of 
those hazardous materials. 

[Amdt. 172–29, 41 FR 15997, Apr. 15, 1976, as 
amended by 66 FR 45379, Aug. 28, 2001]

Pipeline and Haz. Matls. Safety Admin., DOT 

§ 172.101 

§ 172.3

Applicability. 

(a) This part applies to— 
(1) Each person who offers a haz-

ardous material for transportation, and 

(2) Each carrier by air, highway, rail, 

or water who transports a hazardous 
material. 

(b) When a person, other than one of 

those provided for in paragraph (a) of 
this section, performs a packaging la-
beling or marking function required by 
this part, that person shall perform the 
function in accordance with this part. 

[Amdt. 172–29, 41 FR 15996, Apr. 15, 1976, as 
amended by Amdt. 172–32, 41 FR 38179, Sept. 
9, 1976] 

Subpart B—Table of Hazardous 

Materials and Special Provisions 

§ 172.101

Purpose and use of haz-

ardous materials table. 

(a) The Hazardous Materials Table 

(Table) in this section designates the 
materials listed therein as hazardous 
materials for the purpose of transpor-
tation of those materials. For each 
listed material, the Table identifies the 
hazard class or specifies that the mate-
rial is forbidden in transportation, and 
gives the proper shipping name or di-
rects the user to the preferred proper 
shipping name. In addition, the Table 
specifies or references requirements in 
this subchapter pertaining to labeling, 
packaging, quantity limits aboard air-
craft and stowage of hazardous mate-
rials aboard vessels. 

(b) 

Column 1: Symbols. 

Column 1 of the 

Table contains six symbols (‘‘ + ’’, ‘‘A’’, 
‘‘D’’, ‘‘G’’, ‘‘I’’ and ‘‘W’’) as follows: 

(1) The plus (+) sign fixes the proper 

shipping name, hazard class and pack-
ing group for that entry without regard 
to whether the material meets the defi-
nition of that class, packing group or 
any other hazard class definition. When 
the plus sign is assigned to a proper 
shipping name in Column (1) of the 
§ 172.101 Table, it means that the mate-
rial is known to pose a risk to humans. 
When a plus sign is assigned to mix-
tures or solutions containing a mate-
rial where the hazard to humans is sig-
nificantly different from that of the 
pure material or where no hazard to 
humans is posed, the material may be 
described using an alternative shipping 

name that represents the hazards posed 
by the material. An appropriate alter-
nate proper shipping name and hazard 
class may be authorized by the Asso-
ciate Administrator. 

(2) The letter ‘‘A’’ denotes a material 

that is subject to the requirements of 
this subchapter only when offered or 
intended for transportation by aircraft, 
unless the material is a hazardous sub-
stance or a hazardous waste. A ship-
ping description entry preceded by an 
‘‘A’’ may be used to describe a material 
for other modes of transportation pro-
vided all applicable requirements for 
the entry are met. 

(3) The letter ‘‘D’’ identifies proper 

shipping names which are appropriate 
for describing materials for domestic 
transportation but may be inappro-
priate for international transportation 
under the provisions of international 
regulations (e.g., IMO, ICAO). An alter-
nate proper shipping name may be se-
lected when either domestic or inter-
national transportation is involved. 

(4) The letter ‘‘G’’ identifies proper 

shipping names for which one or more 
technical names of the hazardous ma-
terial must be entered in parentheses, 
in association with the basic descrip-
tion. (See § 172.203(k).) 

(5) The letter ‘‘I’’ identifies proper 

shipping names which are appropriate 
for describing materials in inter-
national transportation. An alternate 
proper shipping name may be selected 
when only domestic transportation is 
involved. 

(6) The letter ‘‘W’’ denotes a material 

that is subject to the requirements of 
this subchapter only when offered or 
intended for transportation by vessel, 
unless the material is a hazardous sub-
stance or a hazardous waste. A ship-
ping description entry preceded by a 
‘‘W’’ may be used to describe a mate-
rial for other modes of transportation 
provided all applicable requirements 
for the entry are met. 

(c) 

Column 2: Hazardous materials de-

scriptions and proper shipping names. 

Column 2 lists the hazardous materials 
descriptions and proper shipping names 
of materials designated as hazardous 
materials. Modification of a proper 
shipping name may otherwise be re-
quired or authorized by this section. 
Proper shipping names are limited to 

154 

49 CFR Ch. I (10–1–23 Edition) 

§ 172.101 

those shown in Roman type (not 
italics). 

(1) Proper shipping names may be 

used in the singular or plural and in ei-
ther capital or lower case letters. 
Words may be alternatively spelled in 
the same manner as they appear in the 
ICAO Technical Instructions or the 
IMDG Code. For example ‘‘aluminum’’ 
may be spelled ‘‘aluminium’’ and ‘‘sul-
fur’’ may be spelled ‘‘sulphur’’. How-
ever, the word ‘‘inflammable’’ may not 
be used in place of the word ‘‘flam-
mable’’. 

(2) Punctuation marks and words in 

italics are not part of the proper ship-
ping name, but may be used in addition 
to the proper shipping name. The word 
‘‘or’’ in italics indicates that there is a 
choice of terms in the sequence that 
may alternately be used as the proper 
shipping name or as part of the proper 
shipping name, as appropriate. For ex-
ample, for the hazardous materials de-
scription ‘‘Carbon dioxide, solid or Dry 
ice’’ either ‘‘Carbon dioxide, solid’’ or 
‘‘Dry ice’’ may be used as the proper 
shipping name; and for the hazardous 
materials description ‘‘Articles, pres-
surized pneumatic or hydraulic,’’ ei-
ther ‘‘Articles, pressurized pneumatic’’ 
or ‘‘Articles, pressurized hydraulic’’ 
may be used as the proper shipping 
name. 

(3) The word ‘‘poison’’ or ‘‘poisonous’’ 

may be used interchangeably with the 
word ‘‘toxic’’ when only domestic 
transportation is involved. The abbre-
viation ‘‘n.o.i.’’ or ‘‘n.o.i.b.n.’’ may be 
used interchangeably with ‘‘n.o.s.’’. 

(4) Except for hazardous wastes, when 

qualifying words are used as part of the 
proper shipping name, their sequence 
in the package markings and shipping 
paper description is optional. However, 
the entry in the Table reflects the pre-
ferred sequence. 

(5) When one entry references an-

other entry by use of the word ‘‘see’’, if 
both names are in Roman type, either 
name may be used as the proper ship-
ping name (e.g., Ethyl alcohol, 

see 

Eth-

anol). 

(6) When a proper shipping name in-

cludes a concentration range as part of 
the shipping description, the actual 
concentration, if it is within the range 
stated, may be used in place of the con-
centration range. For example, an 

aqueous solution of hydrogen peroxide 
containing 30 percent peroxide may be 
described as ‘‘Hydrogen peroxide, aque-
ous solution 

with not less than 20 percent 

but not more than 40 percent hydrogen 
peroxide’’ 

or ‘‘Hydrogen peroxide, aque-

ous solution 

with 30 percent hydrogen 

peroxide.

’’ Also, the percent sign (%) 

may be used in place of the word ‘‘per-
cent’’ when words in italics containing 
the word ‘‘percent’’ are used in addi-
tion to the proper shipping name. 

(7) Use of the prefix ‘‘mono’’ is op-

tional in any shipping name, when ap-
propriate. Thus, Iodine monochloride 
may be used interchangeably with Io-
dine chloride. In ‘‘Glycerol alpha- 
monochlorohydrin’’ the term ‘‘mono’’ 
is considered a prefix to the term 
‘‘chlorohydrin’’ and may be deleted. 

(8) Use of the word ‘‘liquid’’ or 

‘‘solid’’. The word ‘‘liquid’’ or ‘‘solid’’ 
may be added to a proper shipping 
name when a hazardous material spe-
cifically listed by name may, due to 
differing physical states, be a liquid or 
solid. When the packaging specified in 
Column 8 is inappropriate for the phys-
ical state of the material, the table 
provided in paragraph (i)(4) of this sec-
tion should be used to determine the 
appropriate packaging section. 

(9) 

Hazardous wastes. 

If the word 

‘‘waste’’ is not included in the haz-
ardous material description in Column 
2 of the Table, the proper shipping 
name for a hazardous waste (as defined 
in § 171.8 of this subchapter), shall in-
clude the word ‘‘Waste’’ preceding the 
proper shipping name of the material. 
For example: Waste acetone. 

(10) 

Mixtures and solutions. 

(i) A mix-

ture or solution meeting the definition 
of one or more hazard class that is not 
identified specifically by name, com-
prised of a single predominant haz-
ardous material identified in the Table 
by technical name and one or more 
hazardous and/or non-hazardous mate-
rial, must be described using the proper 
shipping name of the hazardous mate-
rial and the qualifying word ‘‘mixture’’ 
or ‘‘solution’’, as appropriate, unless— 

(A) Except as provided in 

§ 172.101(i)(4) the packaging specified in 
Column 8 is inappropriate to the phys-
ical state of the material; 

(B) The shipping description indi-

cates that the proper shipping name 

155 

Pipeline and Haz. Matls. Safety Admin., DOT 

§ 172.101 

applies only to the pure or technically 
pure hazardous material; 

(C) The hazard class, packing group, 

or subsidiary hazard of the mixture or 
solution is different from that specified 
for the entry; 

(D) There is a significant change in 

the measures to be taken in emer-
gencies; 

(E) The material is identified by spe-

cial provision in Column 7 of the 
§ 172.101 Table as a material poisonous 
by inhalation; however, it no longer 
meets the definition of poisonous by in-
halation or it falls within a different 
hazard zone than that specified in the 
special provision; or 

(F) The material can be appro-

priately described by a shipping name 
that describes its intended application, 
such as ‘‘Coating solution’’, ‘‘Extracts, 
flavoring’’ or ‘‘Compound, cleaning liq-
uid.’’. 

(ii) If one or more of the conditions 

in paragraphs (c)(10)(i)(A) through (F) 
of this section is satisfied then the 
proper shipping name selection process 
in (c)(12)(ii) must be used. 

(iii) A mixture or solution meeting 

the definition of one or more hazard 
class that is not identified in the Table 
specifically by name, comprised of two 
or more hazardous materials in the 
same hazard class, must be described 
using an appropriate shipping descrip-
tion (e.g., ‘‘Flammable liquid, n.o.s.’’). 
The name that most appropriately de-
scribes the material shall be used; e.g., 
an alcohol not listed by its technical 
name in the Table shall be described as 
‘‘Alcohol, n.o.s.’’ rather than ‘‘Flam-
mable liquid, n.o.s.’’. Some mixtures 
may be more appropriately described 
according to their application, such as 
‘‘Coating solution’’ or ‘‘Extracts, fla-
voring liquid’’ rather than by an n.o.s. 
entry. Under the provisions of subparts 
C and D of this part, the technical 
names of at least two components most 
predominately contributing to the haz-
ards of the mixture or solution may be 
required in association with the proper 
shipping name. 

(11) Except for a material subject to 

or prohibited by § 173.21, § 173.54, 
§ 173.56(d), § 173.56(e), § 173.224(c) or 
§ 173.225(b) of this subchapter, a mate-
rial that is considered to be a haz-
ardous waste or a sample of a material 

for which the hazard class is uncertain 
and must be determined by testing 
may be assigned a tentative proper 
shipping name, hazard class, identifica-
tion number and packing group, if ap-
plicable, based on the shipper’s ten-
tative determination according to: 

(i) Defining criteria in this sub-

chapter; 

(ii) The hazard precedence prescribed 

in § 173.2a of this subchapter; 

(iii) The shipper’s knowledge of the 

material; 

(iv) In addition to paragraphs 

(c)(11)(i) through (iii) of this section, 
for a sample of a material other than a 
waste, the following must be met: 

(A) Except when the word ‘‘Sample’’ 

already appears in the proper shipping 
name, the word ‘‘Sample’’ must appear 
as part of the proper shipping name or 
in association with the basic descrip-
tion on the shipping paper. 

(B) When the proper shipping descrip-

tion for a sample is assigned a ‘‘G’’ in 
Column (1) of the § 172.101 Table, and 
the primary constituent(s) for which 
the tentative classification is based are 
not known, the provisions requiring a 
technical name for the constituent(s) 
do not apply; and 

(C) A sample must be transported in 

a combination packaging that con-
forms to the requirements of this sub-
chapter that are applicable to the ten-
tative packing group assigned, and 
may not exceed a net mass of 2.5 kg (5.5 
pounds) per package.

OTE TO PARAGRAPH

(c)(11): For the trans-

portation of samples of self-reactive mate-
rials, organic peroxides, explosives or light-
ers, 

see 

§ 173.224(c)(3), § 173.225(c)(2), § 173.56(d) 

or § 173.308(b)(2) of this subchapter, respec-
tively. 

(12) Except when the proper shipping 

name in the Table is preceded by a plus 
(+)— 

(i) If it is specifically determined 

that a material meets the definition of 
a hazard class, packing group or hazard 
zone, other than the class, packing 
group or hazard zone shown in associa-
tion with the proper shipping name, or 
does not meet the defining criteria for 
a subsidiary hazard shown in Column 6 
of the Table, the material shall be de-
scribed by an appropriate proper ship-
ping name listed in association with 
the correct hazard class, packing 

156

§ 172.101 

group, hazard zone, or subsidiary haz-
ard for the material. 

(ii) 

Generic or n.o.s. descriptions. 

If an 

appropriate technical name is not 
shown in the Table, selection of a prop-
er shipping name shall be made from 
the generic or n.o.s. descriptions cor-
responding to the specific hazard class, 
packing group, hazard zone, or sub-
sidiary hazard, if any, for the material. 
The name that most appropriately de-
scribes the material shall be used; e.g., 
an alcohol not listed by its technical 
name in the Table shall be described as 
‘‘Alcohol, n.o.s.’’ rather than ‘‘Flam-
mable liquid, n.o.s.’’. Some mixtures 
may be more appropriately described 
according to their application, such as 
‘‘Coating solution’’ or ‘‘Extracts, fla-
voring, liquid’’, rather than by an n.o.s. 
entry, such as ‘‘Flammable liquid, 
n.o.s.’’ It should be noted, however, 
that an n.o.s. description as a proper 
shipping name may not provide suffi-
cient information for shipping papers 
and package markings. Under the pro-
visions of subparts C and D of this part, 
the technical name of one or more con-
stituents which makes the product a 
hazardous material may be required in 
association with the proper shipping 
name. 

(iii) 

Multiple hazard materials. 

If a ma-

terial meets the definition of more 
than one hazard class, and is not iden-
tified in the Table specifically by name 
(e.g., acetyl chloride), the hazard class 
of the material shall be determined by 
using the precedence specified in 
§ 173.2a of this subchapter, and an ap-
propriate shipping description (e.g., 
‘‘Flammable liquid, corrosive n.o.s.’’) 
shall be selected as described in para-
graph (c)(12)(ii) of this section. 

(iv) If it is specifically determined 

that a material is not a forbidden ma-
terial and does not meet the definition 
of any hazard class, the material is not 
a hazardous material. 

(13) 

Self-reactive materials and organic 

peroxides. 

A generic proper shipping 

name for a self-reactive material or an 
organic peroxide, as listed in Column 2 
of the Table, must be selected based on 
the material’s technical name and con-
centration, in accordance with the pro-
visions of § 173.224 or § 173.225 of this 
subchapter, respectively. 

(14) A proper shipping name that de-

scribes all isomers of a material may 
be used to identify any isomer of that 
material if the isomer meets criteria 
for the same hazard class or division, 
subsidiary risk(s) and packing group, 
unless the isomer is specifically identi-
fied in the Table. 

(15) Unless a hydrate is specifically 

listed in the Table, a proper shipping 
name for the equivalent anhydrous 
substance may be used, if the hydrate 
meets the same hazard class or divi-
sion, subsidiary risk(s) and packing 
group. 

(16) Unless it is already included in 

the proper shipping name in the 
§ 172.101 Table, the qualifying words 
‘‘liquid’’ or ‘‘solid’’ may be added in as-
sociation with the proper shipping 
name when a hazardous material spe-
cifically listed by name in the § 172.101 
Table may, due to the differing phys-
ical states of the various isomers of the 
material, be either a liquid or a solid 
(for example ‘‘Dinitrotoluenes, liquid’’ 
and ‘‘Dinitrotoluenes, solid’’). Use of 
the words ‘‘liquid’’ or ‘‘solid’’ is subject 
to the limitations specified for the use 
of the words ‘‘mixture’’ or ‘‘solution’’ 
in paragraph (c)(10) of this section. The 
qualifying word ‘‘molten’’ may be 
added in association with the proper 
shipping name when a hazardous mate-
rial, which is a solid in accordance 
with the definition in § 171.8 of this sub-
chapter, is offered for transportation in 
the molten state (for example, 
‘‘Alkylphenols, solid, n.o.s., molten’’). 

(17) Unless it is already included in 

the proper shipping name in the 
§ 172.101 Table, the qualifying word 
‘‘stabilized’’ may be added in associa-
tion with the proper shipping name, as 
appropriate, where without stabiliza-
tion the substance would be forbidden 
for transportation according to 
§ 173.21(f) of this subchapter. 

(d) 

Column 3: Hazard class or Division. 

Column 3 contains a designation of the 
hazard class or division corresponding 
to each proper shipping name, or the 
word ‘‘Forbidden’’. 

(1) A material for which the entry in 

this column is ‘‘Forbidden’’ may not be 
offered for transportation or trans-
ported. This prohibition does not apply 
if the material is diluted, stabilized or 
incorporated in a device and it is 

157 

Pipeline and Haz. Matls. Safety Admin., DOT 

§ 172.101 

classed in accordance with the defini-
tions of hazardous materials contained 
in part 173 of this subchapter. 

(2) When a reevaluation of test data 

or new data indicates a need to modify 
the ‘‘Forbidden’’ designation or the 
hazard class or packing group specified 
for a material specifically identified in 
the Table, this data should be sub-
mitted to the Associate Administrator. 

(3) A basic description of each hazard 

class and the section reference for class 
definitions appear in § 173.2 of this sub-
chapter. 

(4) Each reference to a Class 3 mate-

rial is modified to read ‘‘Combustible 
liquid’’ when that material is reclassi-
fied in accordance with § 173.150(e) or (f) 
of this subchapter or has a flash point 
above 60 

°

C (140

(e) 

Column 4: Identification number. 

Column 4 lists the identification num-
ber assigned to each proper shipping 
name. Those preceded by the letters 
‘‘UN’’ are associated with proper ship-
ping names considered appropriate for 
international transportation as well as 
domestic transportation. Those pre-
ceded by the letters ‘‘NA’’ are associ-
ated with proper shipping names not 
recognized for transportation outside 
of the United States. Identification 
numbers in the ‘‘NA9000’’ series are as-
sociated with proper shipping names 
not appropriately covered by inter-
national hazardous materials (dan-
gerous goods) transportation stand-
ards, or not appropriately addressed by 
international transportation standards 
for emergency response information 
purposes, except for transportation in 
the United States. Those preceded by 
the letters ‘‘ID’’ are associated with 
proper shipping names recognized by 
the ICAO Technical Instructions (see 
§ 171.7 of this subchapter for avail-
ability). 

(f) 

Column 5: Packing group. 

Column 5 

specifies one or more packing groups 
assigned to a material corresponding to 
the proper shipping name and hazard 
class for that material. Class 2, Class 7, 
and Division 6.2 do not have packing 
groups. Articles in classes other than 
Class 1 are not assigned to packing 
groups. For packing purposes, any re-
quirement for a specific packaging per-
formance level is set out in the appli-

cable packing authorizations of part 
173. Packing Groups I, II, and III indi-
cate the degree of danger presented by 
the material is great, medium, or 
minor, respectively. If more than one 
packing group is indicated for an 
entry, the packing group for the haz-
ardous material is determined using 
the criteria for assignment of packing 
groups specified in subpart D of part 
173. When a reevaluation of test data or 
new data indicates a need to modify 
the specified packing group(s), the data 
should be submitted to the Associate 
Administrator. Each reference in this 
column to a material that is a haz-
ardous waste or a hazardous substance, 
and whose proper shipping name pre-
ceded in Column 1 of the Table by the 
letter ‘‘A’’ or ‘‘W,’’ is modified to read 
‘‘III’’ on those occasions when the ma-
terial is offered for transportation or 
transported by a mode in which its 
transportation is not otherwise subject 
to requirements of this subchapter. 

(g) 

Column 6: Labels. 

Column 6 speci-

fies codes which represent the hazard 
warning labels required for a package 
filled with a material conforming to 
the associated hazard class and proper 
shipping name, unless the package is 
otherwise excepted from labeling by a 
provision in subpart E of this part, or 
part 173 of this subchapter. The first 
code is indicative of the primary haz-
ard of the material. Additional label 
codes are indicative of subsidiary haz-
ards. Provisions in § 172.402 may require 
that a label other than that specified 
in Column 6 be affixed to the package 
in addition to that specified in Column 
6. No label is required for a material 
classed as a combustible liquid or for a 
Class 3 material that is reclassed as a 
combustible liquid. For ‘‘Empty’’ label 
requirements, see § 173.428 of this sub-
chapter. The codes contained in Col-
umn 6 are defined according to the fol-
lowing table:

(h) 

Column 7: Special provisions. 

Col-

umn 7 specifies codes for special provi-
sions applicable to hazardous mate-
rials. When Column 7 refers to a special 
provision for a hazardous material, the 
meaning and requirements of that spe-
cial provision are as set forth in 
§ 172.102 of this subpart. 

(i) 

Column 8: Packaging authorizations. 

Columns 8A, 8B and 8C specify the ap-
plicable sections for exceptions, non- 
bulk packaging requirements and bulk 
packaging requirements, respectively, 
in part 173 of this subchapter. Columns 
8A, 8B and 8C are completed in a man-
ner which indicates that ‘‘§ 173.’’ pre-
cedes the designated numerical entry. 
For example, the entry ‘‘202’’ in Col-
umn 8B associated with the proper 
shipping name ‘‘Gasoline’’ indicates 
that for this material conformance to 
non-bulk packaging requirements pre-
scribed in § 173.202 of this subchapter is 
required. When packaging require-
ments are specified, they are in addi-
tion to the standard requirements for 
all packagings prescribed in § 173.24 of 
this subchapter and any other applica-
ble requirements in subparts A and B 
of part 173 of this subchapter. 

(1) Exceptions. Column 8A contains 

exceptions from some of the require-
ments of this subchapter. The ref-
erenced exceptions are in addition to 
those specified in subpart A of part 173 
and elsewhere in this subchapter. A 
‘‘None’’ in this column means no pack-
aging exceptions are authorized, except 
as may be provided by special provi-
sions in Column 7. 

(2) Non-bulk packaging. Column 8B 

references the section in part 173 of 
this subchapter which prescribes pack-
aging requirements for non-bulk pack-
agings. A ‘‘None’’ in this column means 
non-bulk packagings are not author-
ized, except as may be provided by spe-
cial provisions in Column 7. Each ref-
erence in this column to a material 
which is a hazardous waste or a haz-
ardous substance, and whose proper 
shipping name is preceded in Column 1 
of the Table by the letter ‘‘A’’ or ‘‘W’’, 
is modified to include ‘‘§ 173.203’’ or 
‘‘§ 173.213’’, as appropriate for liquids 
and solids, respectively, on those occa-
sions when the material is offered for 
transportation or transported by a 
mode in which its transportation is not 
otherwise subject to the requirements 
of this subchapter. 

(3) 

Bulk packaging. 

Column (8C) speci-

fies the section in part 173 of this sub-
chapter that prescribes packaging re-
quirements for bulk packagings, sub-
ject to the limitations, requirements, 
and additional authorizations of Col-
umns (7) and (8B). A ‘‘None’’ in Column 
(8C) means bulk packagings are not au-
thorized, except as may be provided by 
special provisions in Column (7) and in 
packaging authorizations Column (8B). 
Additional authorizations and limita-
tions for use of UN portable tanks are 
set forth in Column 7. For each ref-
erence in this column to a material 
that is a hazardous waste or a haz-
ardous substance, and whose proper 
shipping name is preceded in Column 1 
of the Table by the letter ‘‘A’’ or ‘‘W’’ 
and that is offered for transportation 
or transported by a mode in which its 
transportation is not otherwise subject 
to the requirements of this subchapter: 

(i) The column reference is § 173.240 or 

§ 173.241, as appropriate. 

(ii) For a solid material, the excep-

tion provided in special provision B54 is 
applicable. 

(iii) For a Class 9 material, which 

meets the definition of an elevated 
temperature material, the column ref-
erence is § 173.247. 

(4) For a hazardous material which is 

specifically named in the Table and 
whose packaging sections specify pack-
agings not applicable to the form of the 
material (e.g., packaging specified is 
for solid material and the material is 

159 

Pipeline and Haz. Matls. Safety Admin., DOT 

§ 172.101 

being offered for transportation in a 
liquid form) the following table should 
be used to determine the appropriate 
packaging section:

Cylinders. 

For cylinders, both non- 

bulk and bulk packaging authoriza-
tions are set forth in Column (8B). Not-
withstanding a designation of ‘‘None’’ 
in Column (8C), a bulk cylinder may be 
used when specified through the sec-
tion reference in Column (8B). 

(j) 

Column 9: Quantity limitations. 

Col-

umns 9A and 9B specify the maximum 
quantities that may be offered for 
transportation in one package by pas-
senger-carrying aircraft or passenger- 
carrying rail car (Column 9A) or by 
cargo aircraft only (Column 9B), sub-
ject to the following: 

(1) ‘‘Forbidden’’ means the material 

may not be offered for transportation 
or transported in the applicable mode 
of transport. 

(2) The quantity limitation is ‘‘net’’ 

except where otherwise specified, such 
as for ‘‘Consumer commodity’’ which 
specifies ‘‘30 kg gross.’’ 

(3) When articles or devices are spe-

cifically listed by name, the net quan-
tity limitation applies to the entire ar-
ticle or device (less packaging and 
packaging materials) rather than only 
to its hazardous components. 

(4) A package offered or intended for 

transportation by aircraft and which is 
filled with a material forbidden on pas-
senger-carrying aircraft but permitted 
on cargo aircraft only, or which ex-
ceeds the maximum net quantity au-
thorized on passenger-carrying air-
craft, shall be labelled with the CARGO 
AIRCRAFT ONLY label specified in 
§ 172.448 of this part. 

(5) The total net quantity of haz-

ardous material for an outer non-bulk 
packaging that contains more than one 
hazardous material may not exceed the 
lowest permitted maximum net quan-
tity per package as shown in Column 
9A or 9B, as appropriate. If one mate-

rial is a liquid and one is a solid, the 
maximum net quantity must be cal-
culated in kilograms. 

See 

§ 173.24a(c)(1)(iv). 

(k) 

Column 10: Vessel stowage require-

ments. 

Column 10A [Vessel stowage] 

specifies the authorized stowage loca-
tions on board cargo and passenger ves-
sels. Column 10B [Other provisions] 
specifies codes for stowage and han-
dling requirements for specific haz-
ardous materials. Hazardous materials 
offered for transportation as limited 
quantities are allocated stowage cat-
egory A and are not subject to the 
stowage codes assigned by column 10B. 
The meaning of each code in Column 
10B is set forth in § 176.84 of this sub-
chapter. Section 176.63 of this sub-
chapter sets forth the physical require-
ments for each of the authorized loca-
tions listed in Column 10A. (For bulk 
transportation by vessel, see 46 CFR 
parts 30 to 40, 70, 98, 148, 151, 153 and 
154.) The authorized stowage locations 
specified in Column 10A are defined as 
follows: 

(1) Stowage category ‘‘A’’ means the 

material may be stowed ‘‘on deck’’ or 
‘‘under deck’’ on a cargo vessel or on a 
passenger vessel. 

(2) Stowage category ‘‘B’’ means— 
(i) The material may be stowed ‘‘on 

deck’’ or ‘‘under deck’’ on a cargo ves-
sel and on a passenger vessel carrying 
a number of passengers limited to not 
more than the larger of 25 passengers, 
or one passenger per each 3 m of over-
all vessel length; and 

(ii) ‘‘On deck only’’ on passenger ves-

sels in which the number of passengers 
specified in paragraph (k)(2)(i) of this 
section is exceeded. 

(3) Stowage category ‘‘C’’ means the 

material must be stowed ‘‘on deck 
only’’ on a cargo vessel or on a pas-
senger vessel. 

(4) Stowage category ‘‘D’’ means the 

material must be stowed ‘‘on deck 
only’’ on a cargo vessel or on a pas-
senger vessel carrying a number of pas-
sengers limited to not more than the 
larger of 25 passengers or one passenger 
per each 3 m of overall vessel length, 
but the material is prohibited on a pas-
senger vessel in which the limiting 
number of passengers is exceeded. 

(5) Stowage category ‘‘E’’ means the 

material may be stowed ‘‘on deck’’ or 

160 

49 CFR Ch. I (10–1–23 Edition) 

§ 172.101 

‘‘under deck’’ on a cargo vessel or on a 
passenger vessel carrying a number of 
passengers limited to not more than 
the larger of 25 passengers, or one pas-
senger per each 3 m of overall vessel 
length, but is prohibited from carriage 
on a passenger vessel in which the lim-
iting number of passengers is exceeded. 

(6) Stowage category ‘‘01’’ means the 

material may be stowed ‘‘on deck’’ in 
closed cargo transport units or ‘‘under 
deck’’ on a cargo vessel (up to 12 pas-
sengers) or on a passenger vessel. 

(7) Stowage category ‘‘02’’ means the 

material may be stowed ‘‘on deck’’ in 
closed cargo transport units or ‘‘under 
deck’’ on a cargo vessel (up to 12 pas-
sengers) or ‘‘on deck’’ in closed cargo 
transport units or ‘‘under deck’’ in 
closed cargo transport units on a pas-
senger vessel. 

(8) Stowage category ‘‘03’’ means the 

material may be stowed ‘‘on deck’’ in 
closed cargo transport units or ‘‘under 
deck’’ on a cargo vessel (up to 12 pas-
sengers) but the material is prohibited 
on a passenger vessel. 

(9) Stowage category ‘‘04’’ means the 

material may be stowed ‘‘on deck’’ in 
closed cargo transport units or ‘‘under 
deck’’ in closed cargo transports on a 
cargo vessel (up to 12 passengers) but 
the material is prohibited on a pas-
senger vessel. 

(10) Stowage category ‘‘05’’ means the 

material may be stowed ‘‘on deck’’ in 

closed cargo transport units on a cargo 
vessel (up to 12 passengers) but the ma-
terial is prohibited on a passenger ves-
sel.
