Build date

States when the car was built. This is the date every import rule is measured from.

What you have to supply

Nothing but a torch and a phone camera.

Who can order it

Export-market cars almost always carry one. Japanese domestic-market cars almost never do.

Limits and gaps

A JDM-market car normally has no date-bearing label at all. Its caution plate carries model code, chassis number, engine model and paint and trim codes - and no date.

Notes

NHTSA puts this first: the 25-year period runs from the date of manufacture, and the agency looks for that date on a label permanently affixed to the vehicle by its original manufacturer. Everything else on this site exists because that label is missing. Photograph the driver's door aperture, the passenger door aperture, the engine bay bulkhead and the centre pillars before you conclude there isn't one.
