This car cleared both age lines by Apr 2026, 25 years from its date of manufacture. Confirm the build month on the chassis plate before you pay. The EPA exemption covers cars in original configuration only.
The form runs in your browser. With JavaScript off, the example result, the two rules and the chassis-code table below still work. Rules checked November 13, 2026.
The two age lines 二つの年式
Two different agencies, two different counts. A car has to clear both, and they do not fall on the same date.
25 years: NHTSA, safety
A motor vehicle 25 or more years old is exempt from the Federal Motor Vehicle Safety Standards under49 CFR 591.5(i), and the importer declares that on Form HS-7 at the port. NHTSA counts the 25 years from the date of manufacture, which is the build date on the chassis plate, not the model year in a listing. The regulation does not spell out a month-level count; this tool works in months because the plate records a month. Treat the month as the date to confirm.
21 years: EPA, emissions
The emissions route is separate.40 CFR 85.1511(f)(2) exempts a vehicle more than 20 years old when it is imported by a certificate holder, andEPA Form 3520-1 code E, the form ordinary importers file, uses a 21-year test. That test counts calendar years: the year of importation minus the year of manufacture must be at least 21. It also requires the vehicle to be in its original unmodified configuration. A replacement engine of a different model can take a car out of the exemption.
Check the plate, not the listing
A car first registered in 2002 can have been built in late 2001, or the other way round. Ask for a photograph of the chassis plate and the export certificate before you pay.
Current requirements are the ones that apply on the day of entry. Read theNHTSA importation FAQ and theEPA vehicle-import rules.
Chassis codes and production years
The codes the tool recognizes, with the model years each was built. Type either the short code or the full chassis code from the plate.

Common questions
Does the 25-year rule count from the model year or the build date?
From the date of manufacture. Customs and registration documents use the build date on the chassis plate, so two cars sold as the same model year can cross the line months apart. Enter the month and year from the plate, not the model year in an advertisement.
What happens in the month a car turns 25?
The 25 years run from the date of manufacture, and the plate records a month, so this tool treats the car as eligible in that same month 25 years later. The CFR does not spell out a month-level count, so confirm the date with your broker before you book shipping.
Does the EPA exemption work the same way?
No. EPA Form 3520-1 code E counts calendar years: the year of importation minus the year of manufacture must be at least 21. It also requires the vehicle to be in its original configuration, so a replacement engine of a different model can cost a car the exemption.
My chassis code is not in the list. Is the car illegal?
Not necessarily. The list covers the models this site writes about and the common full chassis codes. If your code is not there, the tool still works the dates out from the build month you entered; check the code against the plate and the export certificate.
