Dear Mr. Harrison:
This letter is in response to your January 18, 2016, email requesting clarification of the
Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the
classification of an internal combustion engine with installed Class 1 components.
Specifically, you state that the installed components are classed as two "UN0325, Igniter,
1.4G" and one "UN0275, Cartridge, Power Device Installed" and assigned the Department of
Transportation (DOT) approval number EX-2005010294 and EX-2008010116, respectively.
Your questions have been paraphrased and answered as follows:
Q1. You ask if the basic description "UN3166, Engine, internal combustion, flammable
liquid powered, Class 9" is appropriate and for confirmation that the engine with two
installed igniters and one cartridge, power device would be eligible for the provisions
of § 173.220(f)(1), as they are integral components of the engine and required for its
operation.
Al. Under § 173.56(i), the Associate Administrator for Hazardous Materials Safety may
specify a classification or except an explosive material from the requirements of the
HMR. In the scenario you described, the Associate Administrator has determined that
a 1.4G igniter and a cartridge, power device that are integral parts of the combustion
engine do not pose a hazard requiring an approval and may be excepted if the
requirements of § 173.220(f)(1) are met. Provided the two 1.4G igniters and one
cartridge, power device are integral and necessary for the operation of the engine in
accordance with § 173.220(f)(1), the basic description "UN3166, Engine, internal
combustion, flammable liquid powered, Class 9" would be appropriate. Please note
that this opinion is limited to the facts you presented in your letter.
Q2.
You note that § 173.220(h)(1) exempts engines from placarding requirements when
transported domestically by ground, and you request clarification on the required
hazard communication for international air transport of this engine.

The requirements for the transportation of engines can vary by mode. The modal
exceptions are provided in § 173.220(b)(4).
Please note that this letter of interpretation is based on the information provided specific to the
scenario in question and should not be construed as generally applicable.
I hope this information is helpful. Please contact us if we can be of further assistance.

Hello,
This is to obtain a Formal Letter of Interpretation for the classification of a shipment of a UN3166 Engine, Internal
Combustion, Flammable liquid Powered with two UN0325 1.4G Igniter and a UN0275 1.3C Cartridge, Power Device
Please help with providing information for this domestic shipment.
Shipment:
UN3166 Class 9 Engine, internal combustion, flammable liquid powered. On this engine is fixed and installed, grounded
and shielded two UN0325, Igniter 1.4G (REFERENCE NUMBER EX2005010294) and a UNO275, Cartridge, Power Device
(REFERENCE NUMBER EX2008010116) these are fixed components required for the operation of the engine.
including placarding rules, when shipped by ground in the US and prepared in accordance with 49 CFR 173.220.
Per 49 CFR 173.220(h)(1), Internal Combustion Engines are not subject to the Hazardous Materials Regulations,
With respect to the Igniter and Cartridge, Power Device, see 49 CFR 173.220(f)(1):
"Items containing hazardous materials... that are integral components of the motor vehicle, engine, or mechanical
installed in the motor vehicle, engine, or mechanical equipment. Such items are not otherwise subject to the
equipment and are necessary for the operation of the vehicle, engine, or mechanical equipment.. must be securely

The Two Igniter and One Cartridge, Power Device will be securely installed to the engine. The two Igniters will have
actuation from High Energy Frequency Fields and Electrostatic Discharge while in storage or transporting. The Cartridge
Protective Fraday Cap-Shorting Device installed to provide a ground path from all connector contacts to ground to prevent
will have a Shunt between the wires preventing any connections and a Shielding Cap attached for storage or transporting,
these protective devices will not be removed until the engine is installed on vehicle.
Per IATA UN3166 Packing instruction 950(d)(1)(2): Other operational equipment
These dangerous good UNO325, Igniter 1.4G and UN0275, Cartridge, Power Device would not be required to be reported
on the Dangerous Goods Documents and this shipment would be shipped as a UN3166 Class 9 Engine, Internal
Combustion, Flammable Liquid Powered.
In light of the above information please advise if this shipment can be made using UN3166 Engine, Internal Combustion,
Flammable Liquid Powered,9? Please see attachments for additional information.
Thank you in advance for help!!!!

Dear Mr. Harrison:
This is in response to your letter dated April 2, 2014 requesting clarification of the
Hazardous Material Regulations (HMR; 49 CFR Parts 171-180) applicable to the
classification of an engine with an installed Class 1 component. The installed component is
classed as "UN0325, Igniter, 1.4G" and assigned the Department of Transportation (DOT)
approval number EX-2005010294. Specifically, you ask if the basic description "UN3166,
Engine, internal combustion, flammable liquid powered, Class 9" is appropriate and ask for
confirmation that the engine with installed igniter would be eligible for the provisions of
§ 173.220(f)(1) as the igniter is both an integral component of the engine and required for
operation of the engine. In addition, you note that § 173.220(h)(1) exempts engines from
placarding requirements when transported domestically by ground and request clarification
on the required hazard communication for international air transport of this engine.
Under §173.56(i) of the HMR, the Associate Administrator for Hazardous Materials Safety
may specify a classification or except an explosive material from the requirements of the
HMR. In the scenario described, the AA has determined that a 1.4G igniter that is an integral
part of the combustion engine does not pose a hazard requiring an approval and may be
excepted if the requirements of § 173.220(f)(1) are met. Provided the 1.4G igniter is an
integral component of the engine and necessary for the operation of the engine in accordance
with § 173.220(f)(1), the basic description "UN3166, Engine, internal combustion,
facts you presented in your letter.
flammable liquid powered, Class 9" would be appropriate. This decision is limited to the
The requirements of the HMR apply to all modes of transportation. For domestic
transportation to the airport of departure by motor vehicle or rail car, provided the fuel tank
is securely closed, the engine is not subject to any other requirements under the HMR (e.g.,
shipping papers, labeling, marking, placarding, or emergency response information). Subpart
C of Part 171, authorizes the use of the ICAO Technical Instructions for the Safe Transport
of Dangerous Goods by Air (TI) if any portion of the transportation is by aircraft. Under the
ICAO TI, Packing Instruction 950 provides that dangerous goods required for the operation

of the vehicle, machine, or equipment must be securely mounted to the vehicle, machine, or
equipment, and in addition requires that dangerous goods identified in Table 3-1 as forbidden
on passenger aircraft, only be transported on cargo aircraft. Special Provision A87 excepts
articles, which are not fully enclosed by packaging, crates or other means that prevent ready
identification, from the marking requirements of 5;2 and the labeling requirements of 5;3.
Please note that this letter of interpretation is based on the information provided specific to
information is helpful. If you have further questions, please do not hesitate to contact this
the scenario in question and should not be construed to be generally applicable. I hope this
