Dear Mr. Kelly:
This letter is in response to your September 3, 2019, letter requesting clarification of the
Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the packaging
testing requirements for a limited quantity package via highway transportation. Specifically, you
ask whether a packaging used for a limited quantity shipment by highway is subject to vibration
test requirements in § 178.608.
The answer is no. In accordance with the applicable limited quantity requirements in Part 173, a
limited quantity package transported by highway is excepted from the specification packaging
requirements, including the vibration standard in § 178.608. However, in accordance with
§ 173.24a(a)(5), a packaging used for a limited quantity package must be capable of
withstanding, without rupture or leakage, the vibration test procedure specified in § 178.608.
Meeting this requirement may be based on performance of the test, institutional knowledge, prior
experience, modeling, or other data.
I hope this information is helpful. Please contact us if we can be of further assistance.
Sincerely,
Dirk Der Kinderen
Chief, Standards Development Branch
Standards and Rulemaking Division

Do Packages of Limited Quantities Need to be Tested When Shipped by Ground In
t
_
he United States of America? How shall they be tested?
If I'm shipping a hon-bu.fk package of Paint, U.N1263, P_acking Group H, by ground in the United
States of America as a Limite
_
d Quantity, I am afforded the ex,;:eptions in Column 8A of the
Hazardous Materials Table (HMT). Here in Column 8A, we are referred to Section 173.150.
Section 173.lS0(b) says, we are excepted f~om thE:? specification packaging requirements of this
subchapter when packaged in combination packagings according to THIS paragraph.
It goes on to say, for transportation by aircraft,the package must also conform to Section
173.27 of this part. This is a no brainer. Section 173.27(f)(2)(G)(v), clearly states the package
must be drop tested. Section 173.27(f)(2)(G)(vi), clearly states the package must be stack
tested. I get this and this requirement harmonizes with international regulations {ICAO /
IMDG). We're shipping a non-bulk package by ground. So we stay, right there in Section
173.150.
Are you buckled-up? Here we go. I've already pointed out above, we are excepted from the
specification packaging requirement as long as it is a combination package according to this
paragraph. Also in Section 173.lS0(b), same paragraph mind you, it goes onto say, Each
package must conform to the packaging requirements of subpart B of this part and may not
exceed 30 kgs. Okay where's subpart B? Subpart Bis Preparation of Hazardous Materials for
Transportation. Section 173. Here it is;
§ 173.21 Forbidden materials and packages.
§ 173.22 Shipper's responsibility.
§ 173.22a Use of packagings authorized under special permits.
§ 173.23 Previously authorized packaging.

The List of Dangerous Goods, Subsection 4.2, lists specific dangerous articles and substances
which experience has shown are likely to be offered for transport by air. The list is divided
into 14 columns.
• Column A: provides us with the UN or ID number. The UN number must always be
preceded with the letters UN.
• Column B: provides us with the proper shipping name in bold print. There may be
additional text in light text but not part of the proper shipping name.
• Column C: shows us the hazard class and/or the division.
• Column D: shows us the labels that must be displayed on the package. Primary
hazard labels will be listed first followed by subsidiary risks labels in parenthesis.
• Column E: shows us the packing group in roman numerals I, II, III.

IDENTIFICATION
Not only did the committee of experts create 9 different hazard classes and 3 different
packing groups, they also created proper shipping names for each of these dangerous goods.
(Approximately 3,000 entries) Proper shipping names are shown in alphabetical order in bold
print.
4.1 - SELECTING THE PROPER SHIPPING NAME
Dangerous goods must be assigned to one of the proper shipping names shown in the list of
dangerous goods.
Entries in the list of the dangerous goods are one of four types:
• Single entries for well-defined substances or articles, for example
o Kerosene - UN 1233
o Isopropyl butyrate - UN 2405
• Generic entries for a well-defined group of substances or articles, for example
o Adhesives - UN 1133
o Paint related material - UN 1263
• Specific not otherwise specified (n.o.s.) entries covering a group of substances or
articles, for example
o Refrigerant gas, n.o.s.
- UN 1078
o Selenium compound, solid, n.o.s. - UN 3283
• General n.o.s. entries, for example
o Corrosive solid, n.o.s. - UN 1759
o Flammable liquid n.o.s.
- UN 1993

In summary, a Limited Quantity package prepared for shipment by ground in the United States
of America is excepted from ·
a) Specification Packaging requirements but
b) Must meet the General Packaging requirements as outlined in Sections 173.24,
173.24a, and 178.608 (vibration test) and be in a Strong Outer Package which
c) Brings us to Section 171.8 and back to the aforementioned references
I' m so dizzy my head is spinnin, like a whirlpool it never ends! ·
Section 173.27 makes it crystal clear a Limited Quantity shipped by air, the package must be
dropped tested and stack tested.
Section 173.150 makes it clear as mud as to the package testing requirements for a Limited
Quantity shipped by ground.
If, and that's a big if. If I followed the dots correctly, it appears, a limited quantity package
shipped by ground must be in a strong outer package which has successfully completed a
vibration test.
Question 1) How must the test be recorded?
Question 2) Is the shipper or offerer required to maintain a copy of the vibrati. on
test?
Question 3) Is the result of the test reqtJired to be mar:ked on the ouf,side of the limited
quantity package?

CLASS 7 - RADIOACTIVE MATERIALS
Class 7 does not have any Divisions. It is, however; defined with 3 different categories.
0 CATEGORY WHITE I / YELLOW II / YE LLOW Ill
Radioactive material means any material containing radionuclides where both the activity
concentration and the total activity in the consignment exceed the values specified in Section

CLASS 8 - CORROSIVE MATERIALS
Class 8 does not have any Divisions but it does have 3 packing groups.
The packing group is determined by observing full thickness destruction of intact skin by
utilizing exposure times and observation times.

CLASS g - MISCELLANEOUS
The previous 8 hazard classes have unique and specific definitions.
Either the material meets these definitions or it does not. If you have
a material that does not meet the definition of one of the first 8 hazard
classes, but still poses a risk in transportation, we must classify it as
class 9 miscellaneous.

Question 4) Does Section 178.608 fall under Subpart M which clearly states requirements for
Performance-Orientated Packaging? Which brings us back to 173.150 conflicting
package requirements.
In closing, a limited quantity package by ground inthe:lJili~J~- - States of imerica is excepted
from the Specification Packaging requirements but must ~~et the'.r,equlre: ments in subpart B
(Section 173), which refers us to the Specification Packa~ing ~equlremeJts in Subp~rt M (The

CLASS 4 - FLAMMABLE SOLIDS
• 4.1 - flammable solids
• 4.2 - spontaneous combustible
• 4.3 - dangerous when wet
4.1 Flammable solids, self-reactive substances, Polymerizing Substances and solid de-sensitized
explosives.
4.2 Substances Liable to Spontaneous Combustion - substances liable to spontaneous heating
under normal conditions of transport, or to heating up in contact with air, and then being liable
to catch fire.
4.3 Substance Which in Contact with Water Emit Flammable Gases - substances, which, in contact
with water, emit flammable gases (dangerous when wet). Substances which, by interaction with
water, are liable to become spontaneously flammable or to give off flammable gases in dangerous
quantities.

CLASS 5 - OXIDIZERS
5.1 - Oxidizing substances
Oxidizing substances are not necessarily combustible but may cause or contribute to the combustion
of other materials by yielding oxygen.
5.2 - Organic peroxides
Organic peroxides are liable to exothermic decomposition, which can be started by heat, contact
with impurities (e.g. acids, heavy metal compounds, or amines). For certain organic peroxides, the
temperature must be controlled during transportation.
CLASS 6 - TOXIC AND INFECTIOUS SUBSTANCES
6.1 - toxic or poison substances
• Toxic substances are liable to cause death or injury or to harm human health if swallowed, inhaled
or contacted by the skin.
