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
