§ 172.313
Poisonous hazardous mate-
rials.
In addition to any other markings re-
quired by this subpart:
(a) A material poisonous by inhala-
tion (see § 171.8 of this subchapter) shall
be marked ‘‘Inhalation Hazard’’ in as-
sociation with the required labels or
placards, as appropriate, and shipping
name when required. The marking
must be on two opposing sides of a bulk
packaging. (See § 172.302(b) of this sub-

ages.) When the words ‘‘Inhalation Haz-
ard’’ appear on the label, as prescribed
in §§ 172.416 and 172.429, or placard, as
prescribed in §§ 172.540 and 172.555, the

quired on the package.
(b) Each non-bulk plastic outer pack-
aging used as a single or composite
packaging for materials meeting the
definition of Division 6.1 (in § 173.132 of
this subchapter) shall be permanently
marked, by embossment or other dura-
ble means, with the word ‘‘POISON’’ in
letters at least 6.3 mm (0.25 inch) in
height. Additional text or symbols re-
lated to hazard warning may be in-
cluded in the marking. The marking
shall be located within 150 mm (6
inches) of the closure of the packaging.
(c) A transport vehicle or freight con-
tainer containing a material poisonous
by inhalation in non-bulk packages
shall be marked, on each side and each
end as specified in § 172.332 or § 172.336,
with the identification number speci-
fied for the hazardous material in the
§ 172.101 table, subject to the following
provisions and limitations:
(1) The material is in Hazard Zone A
or B;
(2) The transport vehicle or freight
container is loaded at one facility with
1,000 kg (2,205 pounds) or more aggre-
gate gross weight of the material in
non-bulk packages marked with the
same proper shipping name and identi-
fication number; and
(3) If the transport vehicle or freight
container contains more than one ma-
terial meeting the provisions of this
paragraph (c), it shall be marked with
the identification number for one ma-
terial, determined as follows:
(i) For different materials in the
same hazard zone, with the identifica-
tion number of the material having the
greatest aggregate gross weight; and
(ii) For different materials in both
Hazard Zones A and B, with the identi-
fication number for the Hazard Zone A
material.
(d) For a packaging containing a Di-
vision 6.1 PG III material, ‘‘PG III’’
may be marked adjacent to the POI-
SON label. (See § 172.405(c).)

§ 172.315
Limited quantities.
(a)
Modes other than air transport.
Ex-
cept for an article or substance of Class
7 prepared in accordance with subpart I
of part 173, a package prepared in ac-
cordance with applicable limited quan-
tity requirements in part 173 of this
subchapter and offered for transpor-
tation by a mode other than air must
display the limited quantity marking
shown in paragraph (a)(1) of this sec-
tion. A package displaying this mark is
not subject to the marking require-
ments of § 172.301 of this subpart unless
the limited quantity package also con-
tains a hazardous substance or a haz-
ardous waste. Required markings need
not be duplicated if already marked as
prescribed elsewhere in this subpart.
As an alternative, a packaging may
display the limited quantity ‘‘Y’’ mark
shown in paragraph (b) of this section
if the package conforms to authorized
substance and article provisions and
the inner and outer package quantity
limits in § 173.27(f) of this subchapter.

Marking description.
The top and
bottom portions of the square-on-point
and the border forming the square-on-
point must be black and the center
white or of a suitable contrasting back-
ground as follows:

(2) The square-on-point must be dura-
ble, legible and of a size relative to the
packaging, readily visible, and must be
applied on at least one side or one end
of the outer packaging. The width of
the border forming the square-on-point
must be at least 2 mm and the min-
imum dimension of each side, as meas-
ured from the outside of the lines form-
ing the border, must be 100 mm unless
the packaging size requires a reduced
size marking that must be no less than
50 mm on each side and the width of
the border forming the square on point
may be reduced to a minimum of 1 mm.
Where dimensions are not specified, all
features shall be in approximate pro-
portion to those shown. When intended
for transportation by vessel, a cargo
transport unit (see § 176.2 of this sub-
chapter) containing packages of haz-
ardous materials in only limited quan-
tities must be marked once on each
side and once on each end of the exte-
rior of the unit with an identical mark
which must have minimum dimensions
of 250 mm on each side.
(i)

packaging marked prior to January 1,

service until the end of its useful life.
(3) Except for Class 1 and 7, and Divi-
sion 6.1 and 6.2 materials, for highway
transportation by private motor car-
rier, the limited quantity marking is
not required to be displayed on a pack-
age containing materials assigned to
Packing Group II and III prepared in
accordance with the limited quantity

this subchapter provided:
(i) Inner packagings for liquid haz-
ardous materials do not exceed 1.0 L

2 kg (4.4 pounds) aggregate net quan-
tity of any one hazardous material is
transported per vehicle;
(iv) The total gross weight of all the
limited quantity packages per vehicle
does not exceed 60 kg (132 pounds); and
(v) Each package is marked with the
name and address of the offeror, a 24-
hour emergency response telephone
number and the statement ‘‘Contains

(one-inch) high on a contrasting back-
ground.
(b)
Air transport.
Except for an article

cated if already marked as prescribed
elsewhere in this subpart.

Marking Description.
The top and
bottom portions of the square-on-point
and the border forming the square-on-
point must be black and the center
white or of a suitable contrasting back-
ground and the symbol ‘‘Y’’ must be
black and located in the center of the
square-on-point and be clearly visible
as follows:
(2) The square-on-point must be dura-
ble, legible and of a size relative to the
package as to be readily visible. The
square-on-point must be applied on at
least one side or one end of the outer
packaging. The width of the border
forming the square-on-point must be at
least 2 mm and the minimum dimen-
sion of each side, as measured from the
outside of the lines forming the border,
must be 100 mm unless the package size
requires a reduced size marking that
must be no less than 50 mm on each
side and the width of the border form-
ing the square on point may be reduced
to a minimum of 1 mm. Where dimen-
sions are not specified, all features
shall be in approximate proportion to
those shown.

section may use the packaging itself as
the contrasting background for the
center portion of the marking if the
color sufficiently contrasts so that the
black border, top and bottom portions
of the square-on-point, and the ‘‘Y’’
symbol, if applicable, are clearly rec-
ognizable.
