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.

§ 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

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;

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

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

49 CFR Ch. I (10–1–23 Edition)

§ 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

F) but below 93

C (200

F).

(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.

(l)
