Importing a Car from the UK to the USA: What Decides Whether It's Possible
The short answer
You can import a car from the UK into the USA, but whether a particular vehicle is eligible depends mainly on two federal questions. Does it meet US safety standards? Does it meet US emissions standards? Most cars built for the UK market were not certified to either set of US rules. For many recent UK-market vehicles, the practical answer is that importing them for regular road use is difficult or not allowed. Older vehicles and cars originally built to US specification are usually much simpler.
Shipping and paperwork are rarely the deciding factor. The decisive step is confirming, before you buy or ship, which legal route your specific vehicle qualifies for.
Who sets the rules
Three federal agencies are involved, and each one checks something different.
National Highway Traffic Safety Administration (NHTSA): checks compliance with the Federal Motor Vehicle Safety Standards (FMVSS), which cover items such as lighting, crash protection and bumpers. Environmental Protection Agency (EPA): checks compliance with federal emissions standards. U.S. Customs and Border Protection (CBP): handles formal entry of the vehicle at the port, collects any import duty and confirms that the safety and emissions declarations are in place.
After the car clears federal entry, your state's motor vehicle agency handles titling and registration. Some states, notably California, apply their own stricter emissions requirements.
The main routes for a UK car
Route | Typically applies to | Key point; Age-based safety exemption | Vehicles at least 25 years old | NHTSA does not require FMVSS conformity for these vehicles. Emissions eligibility must still be confirmed separately. Age-based emissions exemption | Vehicles at least 21 years old, in original configuration | The EPA exempts these from federal emissions conformity. State rules may still differ. Registered Importer conversion | Newer non-US-spec vehicles on NHTSA's eligibility list | An NHTSA-registered importer must modify and certify the car. This is only possible if the model has been found capable of conversion. US-specification vehicle | Cars originally built to US standards and labelled as such | Usually the simplest case, because certification labels show conformity. Temporary or special-purpose entry | Nonresidents' personal-use imports, show or display, and similar cases | These come with conditions such as time limits or restricted use. They do not give a general right to keep the car permanently on the road.
The 25-year safety rule is the reason classic and older UK cars are the most common personal imports. Eligibility is calculated from the vehicle's date of manufacture, not from its model year or first registration date, so check the exact build date.
For newer UK cars, the Registered Importer route is the only general option, and it is limited. If NHTSA has not found a model capable of conversion, it cannot be imported under this route, and conversion work can be costly. No model-specific eligibility or cost information was available for this guide. Check your exact make, model and year against the current NHTSA eligibility information.
How a UK car differs from a US-market car
Even when the badge matches a model sold in America, the UK version is usually a different vehicle in regulatory terms. Lighting, emissions equipment, safety labelling and sometimes structural details differ. That is why a UK car is not treated as equivalent to its US counterpart.
Right-hand drive is not prohibited by federal law, and right-hand-drive vehicles can be registered in the USA. Driving one on American roads does have practical drawbacks, such as overtaking visibility, toll booths and drive-throughs. Insurers and some states may also have their own requirements, so check locally.
Paperwork you should expect
Proof of ownership, such as the UK V5C registration certificate and a bill of sale. Shipping documents, including the bill of lading from the carrier. NHTSA form HS-7, declaring the vehicle's safety status or exemption. EPA form 3520-1, declaring the vehicle's emissions status or exemption. CBP entry documentation, usually filed with the help of a customs broker. UK-side export steps, such as notifying the DVLA that the vehicle is being permanently exported.
Import duty applies to cars entering the USA. Rates and trade measures affecting vehicles have changed in recent years, so this guide does not give a figure. Confirm the duty that applies on your entry date with CBP or a licensed customs broker.
What to confirm before you commit
The vehicle's exact date of manufacture, and whether it meets the 25-year safety and 21-year emissions thresholds. For newer cars, whether the model appears on NHTSA's import eligibility list, plus a written quote from a Registered Importer. Your state's registration and emissions requirements, especially in California or other states with stricter rules. Current import duty and fees, confirmed with CBP or a customs broker. Insurance availability for the specific vehicle, including if it is right-hand drive.
Gaps in this guide
No confirmed figures were available for shipping costs, conversion costs, current duty rates, processing times or the eligibility of specific models. Treat this article as an overview of how the system works. The requirements that apply to your car should be confirmed directly with NHTSA, the EPA, CBP and your state motor vehicle agency before you buy or ship.
