What Import Codes Mean When You Buy a Car From Overseas

Import codes are the classification system that tells customs and regulators where a car came from and what rules explore to it

When you buy a car from another country, it arrives with an import code — a designation that tracks its origin and determines what inspections, modifications, and paperwork it needs before you can legally drive it. The code itself is not a single number you look up; instead, it is a combination of information: the country it came from, the year it was manufactured, whether it was previously registered elsewhere, and whether it meets the safety and emissions standards of the country you are importing it into.

Different countries use different systems to track imports. The United States uses a combination of the vehicle identification number (VIN), the country of origin marked on the title, and customs entry documents. The European Union uses a different framework tied to EU type-approval certificates. If you are importing a car into the UK, Australia, Canada, or Japan, each has its own import classification system. Understanding which system applies to your purchase is the first step, because the code determines whether you can register the car at all, what it will cost to bring it into compliance, and how long the process takes.

Key Takeaways

Import codes are not a single lookup number but a classification based on the car's origin country, manufacturing year, previous registration history, and whether it meets local safety and emissions standards.
The United States, European Union, UK, Australia, Canada, and Japan each have different import classification systems, and the rules for what cars can be imported vary widely by destination country.
A car's import code determines whether it can be registered at all, what modifications or inspections are required, and how much the import process will cost.
Most countries restrict or ban the import of cars that do not meet their safety and emissions standards, even if the car is legal in its country of origin.
You should check your country's customs and vehicle registration authority before purchasing an imported car, because some vehicles cannot be legally imported regardless of their condition.

How import codes work in the United States

In the United States, there is no single "import code" label, but the U.S. Customs and Border Protection (CBP) and the National Highway Traffic Safety Administration (NHTSA) use the VIN and country of origin to determine import rules. When a car crosses the border, CBP records the country it came from. NHTSA then checks whether the car meets Federal Motor Vehicle Safety Standards (FMVSS) and Environmental Protection Agency (EPA) emissions standards.

Cars imported into the U.S. fall into two broad categories: those that meet U.S. standards from the factory, and those that do not. A Japanese car built to Japanese specifications may not meet U.S. safety or emissions rules. If it does not, you cannot register it in most states unless it is at least 25 years old — a rule called the "25-year rule" that allows older vehicles to be imported as classics without modification. Cars younger than 25 years that do not meet U.S. standards cannot be legally registered, even if you modify them later.

If you are importing a car from Canada or Mexico, the rules are slightly different because those countries have trade agreements with the U.S. A car built in Canada or Mexico to North American standards may be easier to import than one from Japan or Europe. You will need to provide CBP with a bill of sale, proof of ownership, and documentation of the car's origin. CBP will assign an entry number and assess duties based on the car's value.

Import codes in the European Union and UK

The European Union uses a type-approval system tied to EU safety and emissions standards. A car sold in one EU country can be freely registered in another because they all meet the same baseline standards. However, if you are importing a car from outside the EU — from Japan, the United States, or elsewhere — it must meet EU standards or be modified to do so.

The UK left the EU and now has its own import system. Cars imported into the UK from non-EU countries must meet UK safety and emissions standards, which are currently aligned with EU standards but may diverge over time. The UK's Driver and Vehicle Licensing Agency (DVLA) and the Vehicle and Operator Services Agency (VOSA) handle import classification. A car from Japan or the United States will need a Vehicle Approval Certificate or a Single Vehicle Approval (SVA) test before it can be registered.

An SVA test is an inspection that checks whether the imported car meets UK standards for brakes, lights, emissions, and structural safety. The test costs between £500 and £1,500 depending on the vehicle and the testing station. If the car fails, you must modify it and retest. This process can take several weeks and add significant cost to the import.

Import codes in Australia, Canada, and Japan

Australia has one of the strictest import regimes. The Department of Infrastructure, Transport, Regional Development and Communications (DITRDRC) classifies imported cars based on their origin and age. Cars must meet Australian Design Rules (ADRs) for safety and emissions. Most cars imported into Australia must be at least 15 years old, and they must pass an inspection by an Authorized Inspection Station (AIS). Newer cars can be imported only if they are from a country with an approved type-approval system — currently limited to a small number of countries.

Canada allows imports from the United States and Mexico under USMCA (formerly NAFTA), and also permits imports from other countries if they meet Canadian safety and emissions standards. Transport Canada handles the classification. The process is generally faster than in Australia or the UK, but you still need to provide proof that the car meets Canadian standards or arrange for modifications.

Japan restricts imports heavily. Most imported cars must be at least 3 years old, and they must pass a Japanese vehicle inspection (shaken) that covers safety, emissions, and roadworthiness. The Japan Customs Service assigns an import code based on the car's origin and specifications. Importing a car into Japan is expensive and time-consuming, and many cars from the United States or Europe cannot be imported at all because they do not meet Japanese safety or emissions standards.

What happens if your car does not match its import code

If you purchase a car and its actual specifications do not match the import code assigned to it, you face registration problems. For example, if a car is coded as meeting U.S. safety standards but was actually built to Japanese specifications, the registration authority will reject it. You cannot straightforward re-code it or explore for a different classification — the code is based on the car's actual origin and manufacture date, not on what you want it to be.

In some cases, you can modify the car to bring it into compliance with local standards. In the United States, this is possible for cars younger than 25 years only if the modifications are certified by the manufacturer or by an authorized modifier. In the EU and UK, modifications must be documented and the car must pass a re-inspection. In Australia, modifications are rarely permitted for cars younger than 15 years, and the cost often exceeds the car's value.

If the car cannot be modified or does not meet standards, your only option is to export it again or scrap it. This is why checking the import code and local regulations before you purchase is critical — buying a car that cannot be imported is a total loss.

How to check import codes before you buy

Before purchasing an imported car, contact your country's customs authority and vehicle registration body. In the United States, check with NHTSA using the VIN to see whether the car meets FMVSS standards. You can also contact your state's Department of Motor Vehicles (DMV) to ask whether a car from a specific country and year can be registered.

In the EU and UK, contact your national vehicle registration authority or use the European Commission's type-approval database to check whether a car meets standards. In Australia, check the DITRDRC website for import restrictions by country and age. In Canada, contact Transport Canada. In Japan, contact the Japan Customs Service or a local import broker.

If you are buying from a dealer or private seller, ask them to provide documentation of the car's origin, manufacturing date, and any previous registration history. This information is usually on the title or registration document. If the seller cannot provide it, do not proceed — you will not be able to verify the import code yourself once you own the car.

Working with import brokers and customs agents

If you are importing a car yourself, you may need to work with a customs broker or import agent. These professionals handle the paperwork, arrange inspections, and coordinate with customs authorities. They know the import codes for different countries and can tell you upfront whether a specific car can be imported and what it will cost.

A customs broker typically charges between $500 and $2,000 depending on the complexity of the import and the destination country. They will request the VIN, bill of sale, and proof of ownership, and they will file the necessary documents with customs and the vehicle registration authority. They can also arrange for inspections and modifications if needed.

If you are buying from a dealer that specializes in imported cars, they often handle the import process themselves and include the cost in the sale price. This is usually more expensive than importing privately, but it shifts the risk to the dealer — if the car cannot be registered, they are responsible for resolving it.

Frequently Asked Questions

Can I import a car that does not meet my country's safety standards?

In most countries, no. The United States allows cars older than 25 years regardless of standards. Australia allows cars older than 15 years if they pass inspection. The EU, UK, Canada, and Japan generally require all imported cars to meet local standards or be modified to do so. Check your country's rules before you buy.

What is the 25-year rule in the United States?

Cars that are at least 25 years old are exempt from FMVSS and EPA standards in the U.S. and can be imported without modification. Younger cars must meet U.S. standards or cannot be registered. The age is calculated from the model year, not the purchase date.

Do I need an import code to buy a car from another country?

You do not need an import code to buy the car, but you need to know what the import code will be before you complete the purchase. The code determines whether you can legally register and drive the car in your country. Buying without checking is a major risk.

How long does it take to import a car?

The timeline varies by country and whether the car needs modifications. In the U.S., customs clearance takes a few days to a week. In the UK, an SVA test takes two to four weeks. In Australia, inspections and approvals can take six to eight weeks. Japan can take several months. Plan for at least one to three months for the full process.

What documents do I need to import a car?

You will need the original title or registration document, a bill of sale, proof of ownership, the VIN, and proof of insurance. Some countries also require a customs declaration, an import permit, or a pre-import inspection report. Your customs broker or registration authority can tell you exactly what is required for your destination country.
