How to prove a Honda's build date

The single best evidence there is, and it is free. Look for it before you pay anyone anything.

Nothing but a torch and a phone camera.

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

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.

Japanese recall notices pair exact chassis-number blocks with exact production periods. If your chassis number falls inside a block, your car was built inside that window. It brackets; it does not pin.

The real technique is to find every recall your chassis number falls inside and intersect the production periods. Two or three overlapping recalls can narrow an eighteen-month window to a couple of months. It is an inference, not a certificate, and no authority formally accepts it - but it is free, it is government-published, and you can show your working.

This is the workhorse document of every JDM import, and it does NOT state a build date. Two widely-read broker guides claim it gives a date of manufacture or a build date. Both are wrong.

JPY 350 in revenue stamps; JPY 500 for a kei car. An English translation costs about JPY 5,000-10,000 and is not official.

Handled by your exporter as part of deregistration.

Carries no date of manufacture. Useful for other things; useless for proving a car's age.

What it does give is a first-registration date on an official government document, and that satisfies NHTSA's second tier: a registration document showing the vehicle was registered at least 25 years ago. First registration is always at or after manufacture, so it can only ever make a car look younger than it is - which is why NHTSA accepts it, and why it cannot rescue a borderline car. Australia names the Japanese de-registration certificate explicitly as acceptable evidence. No CBP regulation requires an English translation, but every customs broker treats one as mandatory in practice.

For these six manufacturers there is no route. Ask your dealer anyway, but plan as though the answer is no - because it is.

One exception worth trying: a Mazda dealer employee has publicly stated that dealer systems hold build data for all Mazda vehicles up to around 2004 and offered to look them up. That is one person's informal offer, not a Mazda programme, but it establishes that the data exists inside the dealer network. It costs nothing to ask.

An official MLIT statement of the first registration date and the full registration history from new, independent of the export certificate. The cheapest insurance in the whole process, and almost nobody buys it.

Order it before your exporter deregisters the car. If a US entry officer questions the export certificate, a second government document saying the same thing settles it for JPY 1,200.

Proves nothing about age. A private trading document, trivially forged, accepted by no import authority anywhere.

At least one popular guide claims the sheet shows the actual production month and year. It does not. Use the sheet for condition and history - that is what it is for and it is very good at it.
