The 25-Year Import Rule Explained

Under US federal law, motor vehicles must generally comply with Federal Motor Vehicle Safety Standards (FMVSS) and EPA emissions requirements to be imported permanently. Vehicles that are at least 25 years old are exempted from the FMVSS requirement, because they're treated as collector items rather than everyday transportation that needs to meet current safety mandates.

That's the headline rule most enthusiasts know. The practical effect: once a vehicle's production date is 25 years or older, it becomes dramatically easier to import, title, and register it in most states — including Arizona — without the vehicle needing to be re-engineered to meet modern crash standards.

The 25-year rule isn't the only door in. There are a handful of narrower exemptions that let certain vehicles in earlier — 'show or display' exemptions for historically or technologically significant vehicles, and federalization, where a vehicle is modified and certified to meet FMVSS/EPA standards regardless of age.

Both paths exist, but both come with real strings attached: show-and-display vehicles are typically capped at a small number of miles driven per year, and federalization can be an expensive, time-consuming process involving specialized shops. If your vehicle came in through one of these routes, it changes what documentation we need to write your policy — and sometimes which carriers are even willing to write it.

Insurance carriers care about title status because it tells them how 'real,' from a compliance standpoint, your vehicle's US existence is. A vehicle that's cleared the 25-year rule and has a clean US title behind it is the simplest case to underwrite — it functions, on paper, much like any other titled collector vehicle.

A vehicle imported under show-and-display or federalization carries more nuance: usage restrictions, documentation requirements, and sometimes limits on which state DMVs will register it without extra steps. We ask about this on every quote specifically because it changes which carriers we can shop your policy to and what documentation we'll need up front.

Before we can bind coverage, we typically need your vehicle's title, VIN, and US Customs and Border Protection entry documentation (commonly CBP Form 7501, or equivalent for your import pathway). If your vehicle was federalized, we'll also want the certification paperwork from the shop that did the work.

None of this needs to be intimidating — most of our import clients have already gathered this paperwork by the time they title the vehicle with the Arizona MVD (or their home state's equivalent), and we're happy to walk through exactly what's needed for your specific case before you request a quote.
