Quick Overview of Vehicle and Engine Import Requirements
Introduction
This overview outlines EPA requirements for importing a motor vehicle or engine into
the United States, and is organized by the type of vehicle or engine to be imported. The
Overview also describes requirements for vehicles
which are modified for export, and later returned
to the U.S. For a broader understanding of EPA
requirements, see the Automotive Imports Facts
Manual.
EPA Standard Form 3520-1 must be
submitted to the U.S. Customs Service to import
passenger vehicles, highway motorcycles, and the
corresponding engines into the United States.
Importation of nonroad engines and heavy-duty
highway engines requires EPA Standard Form
3520-21.
Section 1: Permanent Importations of
Vehicles and Engines
1.1 U.S. Version Vehicles
1.1.1 What is a U.S. Version Vehicle?
A U.S. version vehicle is manufactured in
conformity with federal emission requirements.
The manufacturer attaches a label in the engine
compartment that states, in English, that the
vehicle conforms to all EPA regulations. A
vehicle lacking the EPA emission compliance
label is considered non-complying.
Vehicle importers will likely need to
know:
Year of manufacture;
Model year, make, and model of
vehicle (i.e., 1990 Chevy
Lumina);
Whether the vehicle conforms to
U.S. emissions requirements;
Type of fuel the vehicle uses;
Whether the vehicle was
manufactured with or without a
catalytic converter; and
Gross vehicle weight for trucks
Engine importers will likely need to
know:
Engine and ignition type;
Engine power and/or
displacement;
First year the engine was
manufactured;
Whether the engine conforms to
U.S. standards;
Intended use;
Engine, vehicle, or equipment
manufacturer, model and serial
number, engine family name,
and/or type of equipment; and
Build date if uncertified.
Alternative proof is a written statement
from the manufacturer's U.S. representative
stating the vehicle is a U.S. version. EPA does
not accept passing a state inspection test as proof. State inspection tests do not determine
conformity with Federal emission standards. EPA also does not accept having a catalytic
converter as proof. The presence of a catalytic converter does not mean the vehicle is a U.S.
version, or that it meets Federal emission standards.

catalyst and oxygen sensor upon its return to the U.S. To
avoid this expense, you may obtain authorization from EPA to remove the catalyst and oxygen
sensor before the vehicle is shipped overseas. When the vehicle returns to the U.S., you must
file an EPA form 3520-1 with Customs and declare code "F" on the form. Doing so will allow
you to reenter your U.S. version vehicle into the U.S. without bond, upon your assurance that
you will have the reinstallation performed.
1.1.3 EPA Requirements for Importing a U.S. Version Vehicle
The importer must be able to demonstrate that the vehicle is a U.S. version. Note that
Customs may seize a non-U.S. version vehicle if it is falsely declared as a U.S. version.
If the vehicle has been modified or altered, such as

emission components and repair or restore the vehicle to its '--
original certified configuration.
1.1.3.1 U.S. Version Vehicles Modified or Altered
A vehicle originally manufactured as a U.S. version vehicle that has since been modified
or altered, will not meet U.S. emission requirements. For example, if the engine has been altered
or replaced with another type of engine, the vehicle is no longer considered a U.S. version.
A modified or altered vehicle may be conditionally imported as a U.S. version pending
repair and restoration. Upon entry, the importer must file an EPA Form 3520-1 with Customs,
declare code "F" on the form, and post a bond with Customs. The importer has 120 days to
demonstrate to EPA that the vehicle has been repaired or restored to its original configuration.
Alternatively, the vehicle owner may contract with an Independent Commercial Importer
(ICI) that has a valid EPA certificate of conformity to import the vehicle as a non-U.S. version
vehicle and to convert it to meet the EPA requirements. More information on importing non-
U.S. version vehicles with the help of an ICI is included in Section 1.3.2.3.
1.1.3.2 U.S. Version Vehicles Not Modified or Altered
A vehicle originally manufactured as a U.S. version vehicle that has not been modified or
altered may be imported without approval or a Customs bond required by EPA. Upon entry, the
importer must file an EPA Form 3520-1 with Customs, and declare code "B" on the form.
If your vehicle is a U.S. version vehicle, and either the catalyst, oxygen sensor, or fuel
filler neck restrictor were removed for use outside the U.S., or may have become damaged

through leaded fuel use, EPA does not require you to bond the vehicle upon its return to the U.S.
However, you must file an EPA form 3520-1 with Customs and declare code "F" on the form.
The catalyst, and/or oxygen sensor, and/or fuel filler neck restrictor, as applicable, must be
reinstalled or replaced, and if leaded gasoline was used, the fuel tank must be drained and refilled
with unleaded gasoline.
1.1.3.3 Bonded Entries
EPA will require a Customs bond upon importation of a U.S. version vehicle that has
been modified or altered. The bond is needed to ensure that the necessary repair and restoration
work will be completed. Even though the bond amount is set by Customs, EPA recommends to
Customs that the bond be at least the current market value of the vehicle. After a bonded entry
has been made with Customs, the importer has 120 days to bring the vehicle into compliance
with EPA requirements. Otherwise, Customs may seize the vehicle, require the vehicle to be
exported, and seek monetary damages and penalties.

1. 3: Non-V.S. Version Vehicles
manufactured to be sold in Canada and certified to meet , p
the Canadian requirements. They will usually not have
an EPA emissions compliance label, but instead will
have a Transport Canada label.
EPA categorizes Canadian vehicles as either identical to U.S. version vehicles or not
identical to U.S. version vehicles, with regard to emission requirements.
1.2.2 Canadian Version Vehicles ~ Identical to U.S. Version
Anyone may import a Canadian vehicle that is identical in all material respects to a
vehicle certified by EPA for sale in the U.S. No Customs bond or approval is required by EPA
in these cases, but the imported vehicle must meet one of the following two conditions.
For 2002 and newer model year vehicles, the importer must provide a letter from the U.S.
representative of the manufacturer stating that the vehicle met all U.S. emission
requirements when it was manufactured, except possibly for labeling or warranty.
For 1988 to 2001 model year vehicles, the vehicle must be on the EPA list of Canadian
models identical to U.S. version vehicles. The EPA list is located on EPA's Imports
Website and includes all 1988 to 2001 model year Canadian cars and light-duty trucks
(pick-ups and vans under 8,500 GVWR).
For additional information, see the imports website at http://www.epa.gov/otaq/imports.
For importation requirements for 1987 and older model year vehicles, see Section 3.1 below.
Section 1: Permanent Importations of Vehicles and Engines Page 3
-------
Upon entry, the importer must file an EPA Form
3520-1 with Customs declaring code "EE" in block 8 of
that form if for personal use, or code "FF" if for resale. If
the vehicle is not on the EPA list, attach the letter from the
original equipment manufacturer's U.S. representative.
1.2.3 Canadian Version Vehicles For Use by
Immigrants, Workers, and Students
Persons with documented proof of permanent
Canadian immigrant status or Canadian worker or student
status in the U.S. for longer than one year are eligible for an
exemption to import their Canadian vehicles. For those in
the U.S. for less than a year, EPA requires that eligible
importers obtain a nonresident exemption, EPA form 3520-
1 code "O."
Other Federal Agencies
require that the importer
obtain a letter of compliance
from the manufacturer before
attempting to import any
vehicle. The U.S.
representative of the
manufacturer is not required to
issue compliance letters. If you
cannot obtain a letter of
compliance from the
manufacturer you may not be
able to import your vehicle
even if it meets EPA
requirements.
Upon entry, the importer must file an EPA Form 3520-1 with Customs declaring code
"M" on the form, and attach proof that the vehicle is a Canadian version and that the importer
owned the vehicle prior to importation. For proof that the vehicle is a Canadian version
importers may use a copy of the Canadian title or registration, a letter from the manufacturer's
U.S. or Canadian representative stating that the vehicle was manufactured to comply with
applicable Canadian emission requirements, or a sales receipt showing that the vehicle was
purchased new from a Canadian dealership. Adequate proof of ownership before importation
may be a copy of the Canadian title or registration in the name of the importer.
No Customs bond or approval is required by EPA.
1.2.4 Canadian Version Vehicles Received by Inheritance
A U.S. resident is eligible for an EPA exemption if he/she receives a vehicle from a
Canadian resident by inheritance. No Customs bond or approval is required by EPA.
Upon entry, the importer must file an EPA Form 3520-1 with Customs declaring code
"M" on the form, and attach a copy of two documents. The first document must prove the
vehicle was owned by the Canadian resident, such as a copy of the vehicle registration or title in
the name of the Canadian resident. The second document must prove that the vehicle was
obtained from the Canadian resident by inheritance.
1.2.5 Canadian Version Vehicles ~ Other Exemptions
Canadian Vehicles and their importers also have the same requirements as for other non-
U.S. version vehicles and may not use code "EE" or "FF" for non-U.S. version vehicles.
Section 1: Permanent Importations of Vehicles and Engines
Page 4
-------
1.3 Non-U.S. Version Vehicles
1.3.1 What is a non-U.S. version vehicle?
Non-U.S. version vehicles generally are those that
are sold in foreign countries. They will not have the EPA
compliance label. Non-U.S. version vehicles may also
include U.S. version vehicles that have been modified or
altered, other than missing or damaged catalysts, oxygen
sensors, and fuel filler neck restrictors.
EPA does not recommend the
importation of non-conforming
vehicles. Conversion of non-
conforming vehicles is usually
very expensive, and sometimes
impossible or impractical.
Importers with modified U.S. version vehicles may enter the vehicle as a non-conforming
vehicle under the requirements of this section. A non-conforming vehicle is any motor vehicle
or motor vehicle engine not covered by a certificate of conformity. Non-U.S. version vehicles
proven to be identical to U.S. certified version vehicles (e.g., many Canadian vehicles) may be
eligible for exemption as "identical to U.S. version vehicles" or "modified to be identical to U.S.
version vehicles."
An individual may import a non-U.S. version vehicle only (1) if the individual qualifies
for an exclusion (see Excluded Vehicles) or (2) qualifies for and obtains a written letter of
exemption from EPA. A non-U.S. version vehicle may also be imported by an ICI, which is a
private business in the U.S. that holds a current EPA certificate of conformity, and which will
modify and test the vehicle, as applicable, to meet EPA emission requirements.
The importation of non-conforming vehicles is regulated by several Federal agencies,
including EPA, Customs, the Department of Transportation, and the Internal Revenue Service.
Customs will not permit admission of your vehicle until both emission (EPA) and safety
(Department of Transportation) requirements for conditional admission are met.
1.3.2 Permanent Exemptions
Some vehicles which otherwise must be EPA certified to be imported may be eligible for
an exemption from the emission regulations.
1.3.2.1 Vehicles Identical to U.S. Versions
The vehicle may qualify for an exemption if it was
manufactured to be identical to an EPA certified version. No
Customs bond or approval is required by EPA. However, a
vehicle is not eligible for the "identical" exemption if it has been
modified or altered since it was manufactured. Note that an
OEM may not import a vehicle using this exemption.
An "identical" vehicle
may not be imported for
resale, except for
"identical" Canadian
cars and light trucks.
The importer must obtain a letter from the manufacturer's U.S. representative stating the
vehicle met the U. S. emission requirements at the time of manufacture. (See also: 1.2.2
Canadian Version Vehicles Identical to U.S. Version.)
Section 1: Permanent Importations of Vehicles and Engines
Page 5
-------
Upon entry, the importer must file an EPA Form 3520-1 with Customs declaring code
"EE" in item 8 and attach the letter from the manufacturer's U.S. representative, if required.
1.3.2.2 Vehicles Modified to be Identical to U.S. Versions
The vehicle may qualify for an exemption if it is modified to be identical to a U.S.
version. The importer must arrange the importation and modifications with an ICI that holds a
current certificate of conformity from EPA. The ICI must obtain a letter from the manufacturer's
U.S. representative listing the specific modifications required to make the vehicle identical to its
U.S. certified counterpart and then make those modifications in accordance with the
manufacturer's instructions. Upon entry, the ICI must attach the instructions to EPA Form 3520-
1 and declare code Z in block 8 of that form.
1.3.2.3 Importation by an ICI
An ICI is a private business located in the U.S. that has at least one current, valid
certificate of conformity from EPA allowing it to import and modify certain non-conforming
vehicles to bring them into compliance with the EPA requirements. The ICI is not associated
with EPA or the original vehicle manufacturer, and the EPA does not guarantee the work of the
ICI.
Vehicles required to be imported by ICIs must be entered through Customs by the ICI,
not the vehicle owner. The ICI must retain custody until the vehicle has met all EPA
requirements. Those requirements include a fifteen day holding period, after the ICI informs
EPA that all the work and testing have been completed. Before making any purchase or shipping
arrangements, you should be sure that there is an ICI who holds a current, valid EPA certificate;
that the ICI is willing to import your vehicle; and that you are prepared to pay the ICI charges
and wait the necessary time.
1.4 Nonroad or Heavy-Duty Highway Engines
U.S. certified heavy-duty highway engines, certified nonroad engines, or nonroad engines
installed in a certified vehicle, covered by a valid U.S. EPA certificate of conformity and bearing
a U.S. emissions control label in English, can be imported using Form 3520-21 (check box 1).
There are eight categories of nonroad or heavy-duty highway engines, vehicles, and equipment
that must conform to EPA requirements and emission standards under several Federal
regulations. The categories include: heavy-duty highway engines, locomotives, marine
compression-ignition (CI) engines, marine spark-ignition (SI) engines, recreational SI engines,
nonroad CI engines below 37 kW, and all nonroad SI engines.
These engines may be imported as U.S. certified engines or engines installed in certified
vehicles. If this scenario does not apply, the engine may still be imported under certain
circumstances (e.g., exemptions). The exemptions and exclusions available to importers of
nonroad or heavy-duty highway engines are described in further detail below.
Section 1: Permanent Importations of Vehicles and Engines Page 6
-------
1.4.1 Permanent Exemptions for Nonroad or Heavy-duty Highway Engines
In some cases, a permanent exemption may apply to a heavy duty highway engine or
nonroad engine/vehicle, including older engines, manufacturer-owned, replacement engines,
hardship, and configurations identical to a U.S. certified version. If importing a non-conforming
engine under one of the permanent exemptions, importers should check the appropriate
exemption using boxes 2 through 9 on Form 3520-21. The applicable regulatory references are
listed on EPA Form 3520-21.
1.4.2 Other Exemptions for Nonroad or Heavy-duty Highway Engines
For engines that are not yet subject to EPA emission standards, importers should check
box 17 or 18 on Form 3520-21. These include engines that were manufactured before applicable
emission standards were in effect. A recreational marine compression-ignition engine below 2.5
liters per cylinder imported under this provision must be manufactured before the 2006 model
year. A recreational vehicle imported under this provision must be manufactured before the
2007 model year. In addition, certain sterndrive/inboard marine spark-ignition engines may also
be eligible for an exemption if they are not yet subject to EPA standards (see 40 CFR part 91).
There are a number of other specific engine categories and special cases that allow for
importers to claim an exemption. Importers should check the appropriate option from boxes 24
through 27 on Form 3520-21 if they are importing an engine that is subject to the Transition
Program for Equipment Manufacturers, intended for personal-use only, or imported by an ICI.
Some of these exemptions have limitations on the number of engines that can be imported (see
Form 3520-21 for information on the limitations associated with each exemption).
1.4.3 Excluded Engines
In addition to the exemptions that may apply, there are also several engine categories that
EPA does not regulate. These would qualify for an exclusion from EPA's import requirements.
Importers should indicate the appropriate option from boxes 19 through 23 on Form 3520-21 if
importing an engine that is excluded from EPA emission standards. These include engines used
for competition, stationary engines (model year 2006 and before), nonroad CI engines used for
underground mining, and hobby engines. Note that 2007 and later model year Stationary
compression-ignition engines are subject to certification (see: 40 CFR Parts 60 and 89) and thus,
not considered to be excluded engines. In addition, rules for spark-ignition stationary engines
were finalized on January 18, 2008 (see: http://www.epa.gov/fedrgstr/EPA-
AIR/2008/Januarv/Dav-18/a25394.pdf).

Section 1: Permanent Importations of Vehicles and Engines Page 8
-------
Section 2: Temporary Importations
Vehicles and engines imported into the U.S. temporarily for the specific reasons listed
below may be eligible for an exemption from complying with Federal emission requirements.
Vehicles imported under this type of exemption may not be sold or otherwise transferred to
another party in the U.S except with certain restrictions under the diplomatic exemption. Except
for diplomatic use, written EPA approval is required for temporary importation and importers
should keep a copy of the letter for proof of the exclusion. After the purpose of the exemption
has been satisfied, the vehicle must be exported, destroyed, or brought into compliance through
the services of an ICI.
2.1 Repair or Alteration
If a vehicle is imported only for repair or alteration, it may not be operated on public
roads or highways in the U.S. This exemption may not be used for the purpose of converting a
vehicle to meet Federal emission requirements. After the repair or alteration has been made, the
vehicle must be exported.
Upon entry, the importer must file EPA Form 3520-1 with Customs, declare code "G" on
this form, and attach an EPA letter of approval to Form 3520-1. The importer must also post a
bond with Customs.
2.2 Display
Generally, a legitimate display purpose is a display in the interest of the general public or
business. This exemption may not be used for private purposes, and offering a non-conforming
vehicle for sale, as a gift, or as a prize in the U.S. violates the Clean Air Act.
The vehicle may not be operated on public roads or highways in the U.S., except as
necessary for the display purpose (e.g., filming the vehicle for a movie or advertisement).
Driving demonstrations in conjunction with testing programs are permitted only under a testing
exemption. The vehicle must be exported, destroyed or brought into compliance through the
services of an ICI after the display has been completed or at the end of the exemption date,
whichever comes first.
Upon entry, the importer must file an EPA Form 3520-1 with Customs, and declare code
"K" on the form and attach the EPA letter of exemption. The importer must also post a bond
with Customs.
2.3 Testing
If a vehicle or engine is being imported for testing purposes involving research,
investigations, studies, demonstrations, or training, the vehicle or engine may be operated on
public roads only if such operation is an integral part of the test program. The vehicle must be
exported after the testing has been completed or at the end of the exemption date, whichever
comes first.
Section 2: Temporary Importations Page 9
-------
Upon entry, the importer must file an EPA Form 3520-1 with Customs and declare code
"I" on the form and attach the letter of exemption. The importer must also post a bond with
Customs.
2.4 Diplomats or Foreign Military
If a vehicle is being imported temporarily for personal use by a representative of a
foreign government or international organization on assignment in the U.S., the representative
must have authorization for free entry of a vehicle in writing by the U.S. Department of State.
However, for members of the armed forces of a foreign country, their official orders for duty in
the U.S. are considered to be sufficient documentation.
No Customs bond or approval is required by EPA.
Upon entry, the importer must file an EPA Form 3520-1 with Customs, declare code "N"
on the form, and attach a copy of the U.S. Department of State authorization, or orders for duty
in the U.S. for members of the armed forces of foreign countries. Documents from foreign
governments or other U.S. agencies are not acceptable, except for members of the armed forces
of foreign countries.
The vehicle may not be sold or otherwise transferred to another party in the U.S. unless
the new owner has required U.S. Department of State authorization of orders for duty in the U.S.
for members of the armed forces of foreign countries, and the new owner submits a new EPA
form 3520-1 to U.S. Customs.
The vehicle must be exported at the end of the authorizing assignment, or U.S.
Department of State authorization, whichever comes first. Alternatively, the vehicle may be
brought into compliance through the services of an ICI.
2.5 Nonresident
Individual nonresidents may import a vehicle under this exemption if it is being
temporarily imported by a nonresident and primarily for personal use by the importer. Motor
vehicles and motor vehicle equipment for personal use may be imported for up to one year. The
vehicle must be imported in connection with your arrival, and it must be owned by you or on
order before you depart from abroad. The vehicle may not be used to conduct business or for
principle use by persons other than the importer or importer's spouse. The importer must be a
nonresident according to Customs requirements. The vehicle must be exported after one year, or
upon the nonresident departing the U.S., whichever comes first.
No Customs bond is required. However, written EPA approval must be obtained before
clearance at Customs.
Upon entry, the importer must file an EPA Form 3520-1 with Customs and declare code
"O" on the form and attach the EPA letter of exemption. The importer should retain a copy of
the letter as proof of exemption.
Section 2: Temporary Importations Page 10
-------
2.6 Temporary Nonroad or Heavy-duty Highway Engine Imports
There are also a number of temporary exemptions that may apply to nonroad or heavy-
duty highway engines. Importers should check the boxes and review associated definitions on
Form 3520-21 if importing a non-conforming engine under the temporary exemptions for:
Repairs or alterations;
Testing;
Display;
Export (both the engine and shipping container must be labeled or tagged to identify them
solely as export);
Diplomatic or military use (does not apply to locomotive or marine compression-ignition
engines);
Delegated assembly;
A partially complete engine; or
An engine that will be installed in an application not yet subject to EPA emission
standards.

Section 2: Temporary Importations Page 12
-------
Section 3: Exclusions
Some vehicles are excluded from the motor vehicle emission requirements of the Clean
Air Act. Reasons for exclusion include vehicle age (i.e., manufactured prior to the regulations),
fuel type, maximum speed, exclusive use for competition or racing, or lack of features associated
with practical street or highway use. Please note that some vehicles excluded from the motor
vehicle requirements may be subject to non-road vehicle and emission standards which have
become effective in recent years.
3.1 Vehicles at Least 21 Years Old
A vehicle is exempted if it has been 21 years or more since its original production year
and it is in its original unmodified condition. Vehicles in any condition may be excluded if they
were manufactured prior to the year in which EPA's regulations for the class of vehicle took
effect. Vehicles at least 21 years old with replacement engines are not eligible for this
exemption unless they contain equivalent or newer EPA certified engines and emission control
systems. Upon entry, the importer must file an EPA Form 3520-1 with Customs and declare
code "E" on the form.
3.2 Engines Not in a Vehicle or Chassis
EPA regulates the entire vehicle, not individual parts, for cars, light trucks, medium duty
passenger vehicles (MDPVs), chassis-certified HDVs, and motorcycles. If an engine is not
installed, and is to be used in a car, motorcycle, or light truck, it may be imported as an
automotive part. Anyone may import a non-chassis-mounted light-duty engine for use in a
motor vehicle which is currently covered by an EPA certificate or will be covered by an EPA
certificate prior to introduction into commerce. No approval or Customs bond is required by
EPA. However, importers should be aware that several engine uses are violations of the Clean
Air Act:
Mounting an engine to a chassis to "manufacture" a vehicle without proper certification
of conformity from EPA;
Mounting a non-identical engine to a certified vehicle; and
Importing an engine for use in an engine-certified heavy-duty vehicle or heavy-duty truck
without a proper label indicating that it is covered under a certificate of conformity, or
was built prior to 1970, or is otherwise excluded or exempted.
To import an engine for use in a car, light truck, MDPV, chassis-certified HDV, or
motorcycle, the importer must file with Customs, upon entry, an EPA Form 3520-1 and declare
code "W" on the form. For an engine-certified "heavy-duty vehicle" or "heavy-duty truck," EPA
regulates the engine, whether or not it is installed. EPA considers a vehicle or truck "heavy" if it
has a gross vehicle weight rating of more than 8,500 pounds, or a curb weight of more than 6,000
pounds. To be imported, such an engine must be either excluded, exempted, covered by an EPA
certificate of conformity, or imported by an ICI. Note that EPA Form 3520-21 is used to import
heavy duty highway engines.
SectionS: Exclusions Page 13
-------
3.3 Racing Vehicles
Not all vehicles used in races are excluded from emissions compliance. To qualify for
the racing vehicle exclusion, EPA requires specific documentation as proof that the vehicle is
incapable of being safely and practically driven on streets and highways and that it will be used
only for racing. This documentation includes:
1. Importer's name, address, and daytime telephone number;
2. Vehicle information (make, model, model year and VEST);
3. A list of racing features (features that make the vehicle a racing vehicle);
4. A list of street features that are lacking (features that have been removed or have
never been installed that would permit safe driving on streets or highways);
5. At least four photographs showing the front, rear, and each side view; and if a vehicle
with an interior, photographs of the interior;
6. The name of the sanctioning body and competition class;
7. A schedule of racing events, including dates and locations where the vehicle will
participate;
8. A copy of the competition racing license; and
9. Other proof that the vehicle cannot be used on streets and highways, such as a letter
from a state's Department of Motor Vehicles (DMV) that explains the vehicle cannot
be licensed for use on public roads, and explains why it cannot be licensed.
At a later date, the importer may also be required to provide the EPA with proof showing
that the vehicle had been entered into official races. Written EPA approval must be obtained
before clearance at Customs. Upon entry, the importer must file an EPA Form 3520-1 with
Customs, declare code "L" in block 8 of that form, and attach the EPA letter of approval.
Once a racing vehicle is imported, it is a violation of the Clean Air Act to register or
license it for street use, or to convert it into a motor vehicle, unless it is covered by an applicable
EPA certificate of conformity. If an imported racing vehicle is subsequently converted to a
motor vehicle and registered or licensed for street use, the converter may be considered a
manufacturer of a new motor vehicle and subject to a penalty of $25,000 per day for failing to
meet EPA emission requirements.
3.4 Unregulated Fuel Vehicles
Regulated fuels are typically gasoline, diesel, ethanol, methanol, Compressed Natural
Gas (CNG), and Liquid Petroleum Gas (LPG) (including propane) fuels depending on the model
year of the vehicle as described below.
For model years earlier than 1991, gasoline and diesel are
For 2004 and later model
years, only fuel cell and
electric vehicles are
regulated fuels.
unregulated.
For 1990-1996 model years, gasoline, diesel, ethanol, and
methanol are regulated fuels.
For 1997-2003, gasoline, diesel, ethanol, methanol, CNG, and LPG (including propane)
are regulated fuels.
SectionS: Exclusions Page 14
-------
This exemption does not apply to 2004 and later model year vehicles, except for fuel cell
and electric vehicles.
Note that a duel-fueled or multi-fueled vehicle is regulated if it is capable of running on
any regulated fuel.
No Customs bond or approval is required by EPA for unregulated fuel vehicles.
Upon entry, the importer must file an EPA Form 3520-1 with Customs and declare code
"Y" in block 8 of that form.
Converting a vehicle that runs solely on an unregulated fuel to run on a regulated fuel
without a proper certificate of conformity from EPA is a violation of the Clean Air Act.

Secton 4: Motor Vehicle Definition
4.1 Application of section 216(2) 40CFR § 85.1703
(a) For the purpose of determining the applicability of section 216(2), a vehicle which is self-
propelled andcapable of transporting a person or persons or any material or any permanently or
temporarily affixed apparatus shall be deemed a motor vehicle, unless any one or more of the
criteria set forth below are met, in which case the vehicle shall be deemed not a motor vehicle
and excluded from the operation of the Act:
(1) The vehicle cannot exceed a maximum speed of 25 miles per hour over level, paved surfaces;
or
(2) The vehicle lacks features customarily associated with safe and practical street or highway
use, such features including, but not being limited to, a reverse gear (except in the case of
motorcycles), a differential, or safety features required by state and/or federal law; or
(3) The vehicle exhibits features which render its use on a street or highway unsafe, impractical,
or highly unlikely, such features including, but not being limited to, tracked road contact means,
an inordinate size, or features ordinarily associated with military combat or tactical vehicles such
as armor and/or weaponry.
EPA will make written determinations of exclusion for individual vehicle models upon receipt of
dimensions, technical specifications and photographs or drawings of the model in question.
While some vehicles can be easily determined to be excluded, particularly those of inordinate
size, others require more review. An importer that makes his or her own determination does so at
his or her own risk.

*The following vehicles are subject to regulations under parts 90,1051,1065,1068
and 86
4.2 Off-Road/Recreational Vehicles
Off-road/recreational vehicles include, but are not limited to, vehicles such as
snowmobiles, all-terrain vehicles and off-highway motorcycles, utility vehicles, sand cars, and
motorized bicycles.
Note that the deletion,
removal, or absence of
features associated with safe
and practical street or
highway use (that can be
readily added) is not sufficient
grounds for this exclusion.
All 2006 or later model year off-road/recreational
vehicles are subject to certification in accordance with 40
CFRPart 1051. Exclusion determinations for 2005 or
earlier off- road/recreational vehicles are based on the
capability of the subject vehicles to safely and practically
be driven on public roads, not on their intended or
principal use. Model year 2005 and earlier off-
road/recreational vehicles are excluded, unless they also
meet the definition of an on-highway motor vehicle or
motorcycle.
EPA will make written determinations of exclusions for individual vehicle models upon
receipt of dimensions, technical specifications and photographs or drawings of the model in
question. While some vehicles can be easily determined to be excluded, particularly those of
inordinate size, others require more review. An importer that makes his or her own
determination does so at his or her own risk.
EPA Form 3520-1 is no longer used for the importation of nonroad and off-
road/recreational vehicles. The importer must file with Customs, upon entry, an EPA Form
3520-21. For 2006 and later model year vehicles subject to certification, use box 1 or the
appropriate box for an exemption. For 2005 and earlier model year vehicles, you must use box
17 and attach proof that the vehicle was manufactured in 2005 or earlier, is a 2005 or earlier
model, and lacks safety or other features that are required for safe and practical street operation
(including evidence of inordinate size or weight preventing highway use).
A 2005 or earlier model year highway motor scooter or motorcycle with an engine
displacement of less than 50 cc is not regulated, and may be imported without an approval or
Customs bond under EPA declaration code "U" on Form 3520-1. Any 2006 or later model year
highway motor scooter or motorcycle with an engine displacement less than 50 cc is subject to
certification in accordance with 40 CFR Part 86, Subpart E.
Vehicles using this exclusion may not be registered or licensed for use on, or operated on,
the public roads or highways (with the exception of motorized bicycles). Any 2006 or later
model year vehicle must be certified accordance with 40 CFR 1051 and must not be for use in
racing or competition. If an imported off-road/recreational vehicle is subsequently converted to
a motor vehicle and registered or licensed for street use, the converter may be considered a

manufacturer of a new motor vehicle and subject to a penalty of $25,000 per day for failing to
meet EPA emission requirements.
4.3 Imported Used Japanese Mini-trucks and Vans
In recent years, significant numbers of used model year 2004 and older mini-trucks and
vans (also known as Kei-class vehicles) have been imported illegally from Japan into the U.S.
These vehicles, originally manufactured as on-road motor vehicles in Japan, are imported in
violation of the CAA because they were determined by EPA to be uncertified motor vehicles, or
were excluded from motor vehicle regulations and then subsequently modified to operate as a
motor vehicle. Mini-vehicles imported into the U.S. and sold as a nonroad engine or vehicle
must have the permanent physical attributes necessary to ensure that they cannot exceed the 25
mph threshold. Mini-vehicles that are capable of exceeding the 25 mph threshold, either as
originally manufactured or with the speed governing limiters removed, are regulated as "motor
vehicles" under the CAA and must be certified. Note that only modifications approved in
writing by EPA or performed in a manner consistent with EPA-issued guidance are sufficient to
exclude mini-vehicles from the motor vehicle requirements of the CAA.
When EPA or U.S. Customs determines that imported equipment does not meet EPA
emissions certification requirements, Customs will detain or seize the equipment. EPA and
Customs then coordinate on enforcement to address the CAA violations, including collection of a
penalty and exportation of the illegal equipment. The maximum penalty is $32,500 for each
illegal engine or vehicle, although penalties may be reduced for first-time violators and for
importers who voluntarily disclose and remedy the violation and all prior violations.
