Understanding the 25‑Year Rule for Importing Vehicles Not Made in the USA

Ever wondered why you keep hearing that a car must be at least 25years old to be imported into the United States? The rule isn’t a myth - it’s a specific exemption built into U.S. safety and emissions law. Below we break down what the law really says, which vehicles qualify, and how to bring a foreign‑built classic across the Atlantic without hitting a wall.

Key Takeaways

• The 25-year import rule lets cars 25years or older skip most safety and emissions checks.
• Vehicles newer than 25years must meet both NHTSA and EPA standards before they can be cleared.
• You’ll need a valid VIN, the HS‑7 form, and a declaration to Customs and Border Protection (CBP).
• Typical costs include a 2.5% duty, EPA processing fees, and possible bond requirements.
• Common pitfalls: mis‑stating the manufacture date, overlooking required modifications, and skipping the EPA import eligibility check.

What the 25‑Year Exemption Actually Means

In 1988 the National Highway Traffic Safety Administration (NHTSA) set a standard that any vehicle imported into the U.S. must comply with Federal Motor Vehicle Safety Standards (FMVSS). Six months later the Environmental Protection Agency (EPA) added emission compliance requirements under 40CFR Part86. Both agencies agreed on a special carve‑out: any vehicle that is at least 25years old from its date of manufacture is exempt from these certification rules. The exemption is often called the "25‑year rule" and it applies regardless of where the car was built.

Why 25years? The agencies determined that a car that old is unlikely to be driven in regular traffic, so the safety and environmental impact is minimal. It also makes it easier for collectors to bring classic models into the country.

Which Vehicles Actually Qualify?

To claim the exemption, the vehicle must meet three simple criteria:

1. Age: The vehicle must be 25years or older based on the month and year of original manufacture, not the model year.
2. Original VIN: The Vehicle Identification Number (VIN) must be intact and traceable to the manufacturer’s records. A tampered or missing VIN disqualifies the car.
3. No major modifications that affect safety or emissions: Changes like converting a gasoline engine to diesel, adding a turbo, or removing the catalytic converter can trigger a re‑evaluation, forcing the vehicle into the compliance pathway.

Examples of cars that usually qualify include a 1995 Toyota Supra, a 1990 BMW M3, or a 1988 Mazda Miata. A 2020 Honda Civic, even if shipped from Japan, would not be exempt and must undergo a full certification process.

Step‑by‑Step: Importing a Classic Car

Below is a practical checklist that takes you from the dock to the driveway.

1. Verify the manufacture date: Pull the original build sheet from the manufacturer or use a reputable VIN decoder. Record month&year.
2. Gather documentation: You’ll need the original title, a bill of sale, and a HS‑7 form (Declaration of Conformity) completed by the exporter. If the car is older than 25years, you can mark the “Vehicle age exemption” box.
3. Submit to CBP: When the vessel arrives, present the paperwork to Customs and Border Protection (CBP). They will assess duties (usually 2.5% of the declared value) and collect any applicable merchandise processing fees.
4. EPA entry: Even exempt cars must be entered in the EPA’s Import Database. Fill out EPA Form3520‑1 to confirm the 25‑year status. The EPA fee is $85 for passenger vehicles.
5. Transport and registration: After clearance, arrange transport to your state’s motor vehicle agency. Some states require a bond (often $200-$500) to guarantee compliance with any future safety recalls.

If any step fails-say the VIN cannot be verified-the vehicle will be re‑routed for full compliance, which can add months and thousands of dollars in testing.

Costs You’ll Encounter

Remember, the figures above assume the vehicle qualifies for the exemption. If it’s under 25years, you’ll also need to budget for crash‑testing, emissions certification, and possibly a custom “show‑and‑tell” compliance lab, which can push costs above $10,000.

Common Pitfalls & Pro Tips

• Mis‑reading the build date: Some manufacturers label a 1995 model as “1996” in paperwork. Double‑check the VIN decoding report.
• Ignoring state‑specific rules: A few states (e.g., California) have stricter emissions rules even for classics. Verify with the local DMV.
• Skipping the EPA entry: Without Form3520‑1 the CBP will hold the vehicle until EPA clearance, causing delays.
• Using a generic broker: Choose a broker experienced with classic car imports; they’ll know the exact wording for the HS‑7 age exemption.
• Not budgeting for a bond: Some states require a surety bond to protect against future recall repairs.
