Dear Mr. Altemos:
This is in response to your August 28,2008 email requesting clarification of the Hazardous
Materials Regulations (HMR; 49 CFR Parts 17 1 - 180) applicable to shipping paper
requirements. You present a number of scenarios with your interpretation of the applicable
requirements. You ask that we comment on the accuracy of your interpretation. Your
specific scenarios and interpretations, and our responses are as follows:
Scenario 1: The shipping paper states "Fire Extinguisher (Fire
Extinguisher), 2.2, UN 1044, 1 cylinder X 3 kg." The package
marking states "Fire Extinguisher UN1044."
Altemos' Interpretation: This shipping paper description is not in compliance with the
HMR because the words "Fire Extinguisher" have been
interspersed between the required elements of the basic
description, and because this term is not a "technical [or]
chemical group" name specifically allowed to be interspersed
within the required shipping description.
PHMSA .'s Comment: Your interpretation is correct. As required in 5 172.202(d),
technical and chemical group names may be entered in
parentheses between the proper shipping name and hazard class
or following the basic description. An appropriate modifier,
such as "contains" or "containing," and/or the percentage of the
technical constituent may also be used.
Scenario 2: The shipping paper states "Paint (Paint related material), 3,
UN 1263,II, Fiberboard box X 2L." The package marking
states "Paint related material UN 1263."
Altemos' Interpretation: The shipping paper description is not in compliance with the
HMR because the words "Paint Related Material" have been

PHMSA's Comment: Scenario 3: Altemos' Interpretation: PHMSA's Comment:
Scenario 4:
Altemos' Interpretation: interspersed between the required elements of the basic
description, and because this term is not a "technical [or]
chemical group" name specifically allowed to be interspersed
within the required shipping. Moreover, "Paint" and "Paint
related material" are different materials, so although separated
by an "or" in the relevant entry in the Hazardous Materials
Table (HMT), both names cannot be "appropriate" to the
material being described. Finally, the proper shipping name
"Paint" conflicts with the proper shipping name on the
package.
Your interpretation is correct. As specified in 6 172.101(c), the
word "or" in italics indicates that terms in the sequence may be
used as the proper shipping name, as appropriate. In addition,
see PHMSA's comment to Scenario 1.
The shipping paper states "Paint, 3, IJN1263,III, 1 Fiberboard
box X 2L." The package marking states "Paint related material
UN1263 ."
The shipping paper description is not in compliance with the
HMR because "Paint" and "Paint Related Material" are
different materials, the proper shipping name "Paint" conflicts
with the proper shipping name on the package. Alternatively,
since "Paint" and "Paint related materials" are different
materials, if the shipping paper is correct, the package marking
is incorrect.
Your interpretation is correct. In addition, see PHMSA's
comment to Scenario 1 and 2.
The shipping paper states "Air bag inflators or Air bag
Modules, 9, UN3268,III, 1 Fiberboard box X 4 kg." The
package marking states "Air bag inflators UN 3268."
The shipping paper description is not in compliance with the
HMR because the words "Air bag modules" has been
interspersed between the required elements of the basic
description, and because this tern is not a "technical [or]
chemical group" name specifically allowed to be interspersed
within the required shipping description "without limitations"
under the provisions of $ 172.202(d). In this regard, "Air bag
inflators" and "Air bag modules" are different materials, so
although separated by an "or7' in the relevant entry in the HMT,
both names cannot be "appropriate" to the material being
described. Finally, the interspersed term "Air bag modules"

conflicts with the proper shipping name on the package.
Your interpretation is correct. In addition, see PHMSA's
comment to Scenario 1 and 2.
The shipping paper states "Ethanol, 3, UN1170,II, Fiberboard
box X 3 L. The package marking states "Ethanol or Ethyl
Alcohol UN 1 1 70."
The shipping paper description is in compliance with the HMR.
It does not conflict with the package marking, nor does the
packing marking contravene the provisions of the HMR since
no specific sequence is specified for package marking, and
because "Ethanol" and "Ethyl Alcohol" are synonyms for the
same material and both are authorized proper shipping names
for that material (UN1170) under the HMR.
As provided in 4 172.101 (c), when one entry in Column (2) of
the HMT references another entry by use of the word "see," if
both names are in Roman type, either name may be used as the
proper shipping name (e.g., Ethyl alcohol, see Ethanol).
However, this provision does not specify that both entries must
be simultaneously used in the basic description either on the
shipping paper or when marking a non-bulk packaging.
The shipping paper states "Ethanol (Ethyl Alcohol), 3,
UN1170,II, 1 Fiberboard X 1 L." The package marking states
"Ethanol UN 1470.:
The shipping paper description conforms to the HMR since
"Ethanol" and "Ethyl Alcohol" are synonyms for the same
material and both are authorized proper shipping names for that
material under the HMR. Moreover, "Ethyl Alcohol" is a
"technical" name specifically allowed to be interspersed within
the required basic descriptions.
Your interpretation is correct. See PHMSA's comment to
Scenario 1.
The quantity and unit of measure on the shipping paper states
"Acetone, 3, UN1090,II, 1 Fiberboard box X 4 1 L" for which
the "4 1 L" is intended to indicate that the fiberboard box
contains 4 inner packagings each of one liter capacity.
The manner of indicating the total quantity covered by the
description (the shipment concerned is not an air shipment)

<<<PAGE 4>>>

PHMSA's Comment: does not conform to the requirements of 8 172.202(a)(5)
because the numerical value indicating the quantity covered by
the description (i.e., the figure "4" as in 4 liters) is not
immediately followed by an indication of the applicable unit of
measurement (i.e., "Liters" or "L"). Because the HMR do not
require an indication of the number of inner packagings in a
combination packaging, as written, the total quantity covered
by the description could be incorrectly interpreted to be "41 L."
Your interpretation is correct. As specified in 8 172.202(a),
except for transportation by aircraft, the total quantity of
hazardous materials covered by the description must be
indicated (by mass or volume, or by activity for Class 7
materials) and must include an indication of the applicable unit
of measurement. For example, "200 kg" or "50 L."
I hope this information is helpful.
Sincerely,

Subject: Question concerning shipping paper descriptions
Ed and Susan,
I have been asked for my opinion concerning the correctness of a number of shipping paper descriptions (in some
cases, in light of the correspondirlg package marking). However, since I have not been able to find much in the
way of prior interpretations that specifically address the issues concerned, I would appreciate if you could let me
know if I am on target with my views concerning each. In each case, following the description and associated
package marking, I have indicated whether I think the description complies with the applicable provisions of the
HMR or not, along with my rationale for same. I would very much appreciate if you could either confirm my
opinion, or, if I am incorrect, provide an alternative explanation as to the acceptability (or otherwise) of each
description.
Before going into the various descriptions, as I see it the following provisions of the HMR are applicable:
1. 51 72.1 01 (c)(2) - which states that the word "or" in a shipping name sequence in the Hazardous
Materials Table indicates that terms in the proper shipping name sequence may be used as the
proper shipping name "as appropriate".
2. §172.201 (a)(4) - which allows a shipping paper to contain "additional" (i.e., not otherwise required)
information about the material that is not inconsistent with the required description, provided (unless
otherwise permitted or required) that the information is placed after the basic description required by
51 72.202(a).
3. §172.202(b) - which requires that, except as specifically provided, the basic description required by
5172.202(a)(l) to (4) must be shown in sequence with no additional information interspersed.
4. § I 72.202(d) - which allows "technical and chemical group names" to be entered in parentheses
between the proper shipping name and hazard class, or following the basic description. The attached
interpretation letter reference 01-0160 confirms that this is the case "without limitations" (that is, even
when this information is not specifically required for a particular proper shipping name) - as long as
the information is "appropriate and not inconsistent with the proper shipping name". [Note: While I
agree with the basic intent of this interpretation, I believe the specific example cited in the letter is
incorrect because "ethyl benzene" is a distinct chemical compound and not a "xylene", as evidenced
by the fact that ethylbenzene is a separate UN (and HMR) entry with its own UN number (UN 1175).
This being the case, it is not clear how, under the HMR, this could be a "technical name" for a
material described as "xylenes" -or even how a mixture of xylenes and ethylbenzene could be
properly described by the proper shipping name "Xylenes".]
Against that background, the shipping paper descriptions (and corresponding package markings) in question
follow, along with my view regarding the correctness under the HMR of each shipping description.
I. Shipping papers states: Fire Extinguisher (Fire Extinguisher), 2.2, UN1044, 1 cylinder X 3 kg

<<<PAGE 6>>>

Page 2 of 3
Package marking states: Fire Extinguisher UN 1044
In&rpretatiop: This shipping paper description is not in compliance with the HMR because the expression "(Fire
Extinguisher)" has been in interspersed between the required elements of the basic description, and because this
term is not a "technical [or] chemical group" name specifically allowed to be interspersed within the required
shipping description "without limitations" under the provisions of §172.202(d).
2. Shipping paper states : Paint (Paint Related Material), 3, UN1263, II, 1 Fiberboard box X 2 L
Package marking states: Paint Related Material UN1263
Interpretation: This shipping paper description is not in compliance with the HMR because the expression "(Paint
Related Material)" has been in interspersed between the required elements of the basic description, and because
this term is not a "technical [or] chemical group" name specifically allowed to be interspersed within the required
basic description "without limitations" under the provisions of §172.202(d). Moreover, "Paint" and "Paint related
material" are different materials, so, although separated by an "or" in the relevant entry in the Hazardous Materials
Table, both of these names cannot be "appropriate" to the material being described. Finally, the proper shipping
name "Paint" conflicts with the proper shipping name indicated on the package.
3. Shipping paper states: Paint, 3 ,LIN1263, 111, 1 Fiberboard box X 2 L
Package marking states: Paint Related Material UN1263
1.nt.erpretation: This shipping paper description is not in compliance with the HMR because, since "Paint" and
"Paint related material" are different materials, the proper shipping name "Pant" conflicts with the proper shipping
name indicated on the package. Alternatively, since "Paint" and "Paint related material" are different materials, if
the shipping paper entry is correct, the package marking is incorrect.
4. Shipping paper states: Air Bag Inflators or Air Bag Modules, 9, UN3268, 111, 1 Fiberboard box X 4 kg
Package marking states: Air Bag Inflators UN 3268
--
1nterpretati.o-n: This shipping paper description is not in compliance with the HNlR because the expression "or Air
Bag Modules" has been in interspersed between the required elements of the basic description, and because this
term is not a "technical [or] chemical group" name specifically allowed to be interspersed "without limitations"
under the provisions of §172.202(d). In this regard, "Air Bag Inflators" and "Air Bag IModules" are different
materials (see definitions in §173.166(a)), so, although separated by an "or" in the relevant entry in the Hazardous
Materials Table, both of these names cannot be "appropriate" to the material being described. Finally, the
interspersed term "Air Bag Modules" conflicts with the proper shipping name indicated on the package.
5. Shipping paper states: Ethanol, 3, UN1170, II, 1 Fiberboard box X 3 L
Package marking states: Ethanol or Ethyl Alcohol UN1170
1nt.erp~etation: This shipping paper description is in compliance with the HMR. Moreover, it does not conflict with
the package marking, nor does the package marking contravene the provisions of the HMR since for package
markings no specific sequence is specified, and because "Ethanol" and "Ethyl Alcohol" are synonyms for the
same material and both are authorized proper shipping names for that material (UN 1170) under the HMR.
6. Shipping paper states: Ethanol (Ethyl Alcohol), 3, UN1170, II, 1 Fiberboard box X 1 L
Package marking states: Ethanol UN1170
.. . . . . .. ..... . .. . ... .
Interpretation.: This shipping paper description conforms to the HMR since "Ethanol" and "Ethyl Alcohol" are
synonyms for the same material and both are authorized proper shipping names for that material under the HMR.
Moreover, "Efllyl Alcohol" is a "technical" name specifically allowed to be interspersed within the required

basic description "without limitations" under the provisions of §172.202(d)
7. The quantity and unit of measure on the shipping paper states: "Acetone, 3, UN1090, II! 1 Fiberboard box X 4 1
L" for which the "4 '1 L" is intended to indicate that the fiberboard box contains 4 inner packagings each of one liter
capacity.
Interpetation: . This manner of indicating the total quantity covered by the description (the shipment concerned is
not an air shipment) does not conform to the requirements of §172.202(a)(5) because the numerical value
indicating the quantity covered by the description (i.e., the figure "4" as in 4 liters) is not immediately followed by
an indication of the applicable unit of measurement (i.e., Liters" or "L"). Therefore - and because the HMR do not
require an indication of the number of inner packagings in a combination packaging - as written the total quantity
covered by the description could be incorrectly interpreted to be 41 L.
Again, I would appreciate your confirmation that my interpretation of the applicable requirements of the HMR as
they apply to each of these shipping paper entries is correct, or, if not correct, how the requirements would be
properly interpreted in the context of the entry. I very much appreciate your comments and assistance, and
please do not hesitate to contact me if you have questions concerning this request.
Best regards,
Andy
