U.S. EPA, Certification & Compliance Division, 2000 Traverwood Dr., Ann Arbor, Michigan 48105. (734) 214-4100; imports@epa.gov; www.epa.gov/otaq/imports/

This form must be prepared by the importer for each imported nonroad or heavy-duty highway engine, including engines incorporated into vehicles or
equipment. Note that references in this form to engines generally include vehicles or equipment if they are subject to equipment-based standards. One
form per shipment may be used, with attachments including all information required to fully describe each engine as below. Provide a duplicate form
and attachments to the U.S. Customs Service upon request (42 U.S.C. 7522, 7601, 19 CFR 12.73 or 12.74). This form must be retained for five years
from the date of entry (19 CFR 163.4). NOTE: While certain imports require specific written authorization from EPA, Customs may request EPA review
of importer documentation and eligibility for any import using this form. For light-duty motor vehicles, highway motorcycles, and the corresponding
engines, use form 3520-1. This form does not apply to aircraft engines.
Identify the appropriate type of highway or nonroad engine, vehicle, or equipment you are importing from the following list of products:
G A. Heavy-duty highway engines (for use in motor vehicles with gross vehicle weight rating above 8500 pounds). See 40 CFR parts 85 and 86.

G B. Locomotives or locomotive engines. See 40 CFR part 92.

G C. Marine compression-ignition engines. See 40 CFR part 94. This includes propulsion engines and auxiliary engines installed on marine vessels.

G D. Other nonroad compression-ignition engines. See 40 CFR part 89 or 40 CFR parts 1039 and 1068. Note that 40 CFR part 89 also applies to some

marine compression-ignition engines below 37 kW.

G E. Marine spark-ignition engines. See 40 CFR part 91.

G F. Recreational spark-ignition engines and vehicles, including snowmobiles, off-highway motorcycles, all-terrain vehicles, and offroad utility vehicles

that are subject to the same emission standards as all-terrain vehicles. See 40 CFR parts 1051 and 1068. These standards apply to 50 percent of 2006

model-year vehicles and 100 percent of 2007 and later model-year vehicles.

G G. Other nonroad spark-ignition engines at or below 19 kW (or at or below 30 kW if total displacement is at or below 1000 cc). See 40 CFR part 90.

G H. Other nonroad spark-ignition engines above 19 kW (or above 30 kW if displacement is at or below 1000 cc). See 40 CFR parts 1048 and 1068.
