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.
