Under the 25 year import rule, any motor vehicle at least 25 years old, measured from its actual date of manufacture, can be imported into the United States without meeting the Federal Motor Vehicle Safety Standards that apply to newer vehicles. The exemption comes from a single line in federal statute, 49 U.S.C. § 30112(b)(9), which says the prohibition on importing non-certified vehicles “does not apply to a motor vehicle that is at least 25 years old.”1Office of the Law Revision Counsel. 49 U.S. Code 30112 – Prohibitions on Manufacturing, Selling, and Importing Motor Vehicles and Equipment No modifications, no Registered Importer, no compliance bond. If the vehicle is old enough, the safety-standard barrier is simply gone.
How the 25 Years Are Counted
The clock runs from the date the vehicle was actually built, not the model year printed on the title. A car assembled in August 2001 becomes eligible in August 2026, even if it was sold as a 2002 model. If the manufacture date isn’t on a label permanently attached by the original manufacturer, you need documentation proving the age, such as an original sales invoice or a registration record showing the vehicle was registered at least 25 years ago.2National Highway Traffic Safety Administration.

What the Exemption Covers and What It Doesn’t
The 25-year threshold is a NHTSA rule. It clears the vehicle of the Federal Motor Vehicle Safety Standards that govern crash protection, braking, lighting, roof strength, and the rest of the safety catalog.3eCFR. 49 CFR Part 571 – Federal Motor Vehicle Safety Standards
Emissions are regulated separately by the EPA under Title II of the Clean Air Act, and the EPA does not use the same 25-year line.4US EPA. Clean Air Act Title II – Emission Standards for Moving Sources, Parts A Through C For most passenger vehicles the practical result is that a 25-year-old car clears both agencies, but the EPA applies its own criteria and uses a 21-year threshold for what it calls “ancient engines” still in their original configuration.5US EPA. Declaration Form: Importation of Engines, Vehicles, and Equipment Subject to Federal Air Pollution Regulations A vehicle in the 21-to-24-year window may get help on the emissions side while still being blocked on the safety side.
Customs duties are a third, separate matter, and they apply regardless of age. Age does affect one of them, as discussed below.
Paperwork at the Border for an Eligible Vehicle
Three agencies touch every import. NHTSA handles safety, the EPA handles emissions, and U.S. Customs and Border Protection processes the entry and verifies the documentation.6U.S. Customs and Border Protection. Requirements for Importing a Personal Vehicle / Vehicle Parts For a vehicle 25 years or older, you file two forms at the port of entry:
- Form HS-7 for NHTSA, checking the box that declares the age-based exemption.7National Highway Traffic Safety Administration. Form HS-7
- EPA Form 3520-1 for emissions, using the corresponding age exemption.8United States Environmental Protection Agency. Declaration Form: Importation of Motor Vehicles and Motor Vehicle Engines Subject to Federal Air Pollution Regulations
With the age documentation in hand, this is a comparatively simple entry. The complications appear when the vehicle isn’t old enough.
Duties and the 2025 Tariff
Baseline customs duties have been steady for decades and are calculated on the price paid for the vehicle:9U.S. Customs and Border Protection. Importing a Motor Vehicle
- Passenger cars: 2.5%
- Trucks: 25%
- Motorcycles: 2.4% or free, depending on engine size
Starting April 3, 2025, a new 25% tariff applies to imported passenger vehicles and light trucks, stacking on top of the standard duty. A passenger car imported in 2026 would ordinarily face a combined 27.5%. The proclamation explicitly exempts vehicles manufactured at least 25 years before the date of entry, so a car qualifying for the NHTSA age exemption pays only the standard 2.5% duty.10The White House. Adjusting Imports of Automobiles and Automobile Parts Into the United States
CBP also collects a Merchandise Processing Fee on most imports. For fiscal year 2026, the fee ranges from $33.58 to $651.50 per entry.11Federal Register. Customs User Fees To Be Adjusted for Inflation in Fiscal Year 2026 And the Gas Guzzler Tax can apply if the vehicle’s fuel economy falls below 22.5 mpg. The scale starts at $1,000 and climbs to $7,700 for vehicles rated below 12.5 mpg, and for import purposes the importer counts as the manufacturer for tax liability.12Justia. 26 U.S. Code 4064 – Gas Guzzler Tax Many older European sports cars land in the higher brackets.
If the Vehicle Isn’t 25 Years Old Yet
A non-U.S.-spec vehicle that hasn’t reached the 25-year mark faces a much harder path. NHTSA must have already determined that the specific model is eligible for importation, generally because a substantially similar U.S.-certified version exists.13Office of the Law Revision Counsel. 49 U.S. Code 30141 – Importing Motor Vehicles Capable of Complying with Standards If the model isn’t on the eligibility list, it generally cannot come in at all.
Even eligible vehicles must be imported through a Registered Importer, a business specifically approved by NHTSA. The Registered Importer takes possession, performs the required modifications at an approved facility, and permanently attaches a label certifying compliance.14eCFR. 49 CFR 592.6 – Duties of a Registered Importer An Independent Commercial Importer holding an EPA certificate of conformity handles the emissions work. Labor and parts for headlight conversions, bumper changes, side-impact reinforcement, and emissions equipment can run from several thousand dollars into the tens of thousands.15eCFR. 49 CFR Part 594 – Schedule of Fees Authorized by 49 U.S.C. 30141
Before CBP releases the vehicle, the importer must post a conformance bond equal to 150% of the vehicle’s dutiable value.16eCFR. 49 CFR Part 591 – Importation of Vehicles and Equipment Subject to Federal Safety, Bumper, and Theft Prevention Standards The vehicle stays under bond until NHTSA certifies compliance. Missing the deadline forfeits the bond, and the vehicle must be exported or destroyed.
Narrow Exceptions for Younger Vehicles
A handful of exceptions let specific vehicles enter without full compliance, though none of them puts an uncertified car into daily-driver service.
Show or Display
NHTSA can approve import of a vehicle with historical or technological significance even if it can’t meet safety standards. Approved vehicles may be driven on public roads, but the odometer cannot register more than 2,500 miles in any 12-month period, and the owner must carry insurance conditioned on that limit.17NHTSA. How to Import a Motor Vehicle for Show or Display EPA emissions requirements still apply unless the vehicle separately qualifies for an emissions exemption. As of early 2026, roughly 109 specific models had been approved.
Racing Vehicles
Vehicles built exclusively for competitive racing can bypass both safety and emissions rules because they aren’t intended for public roads. “Exclusively” is the operative word: the vehicle cannot be registered for street use, and documentation of its racing purpose is required.
Temporary Import by Non-Residents
Non-residents can bring a personal vehicle in for up to one year without safety or emissions compliance. The vehicle cannot be sold in the U.S. and must be exported before the year is up. No extensions.9U.S. Customs and Border Protection. Importing a Motor Vehicle
Canadian-Market Vehicles
Vehicles originally sold in Canada often already meet U.S. standards. If a Canadian vehicle carries an emissions label stating it meets U.S. EPA federal standards, or the manufacturer’s U.S. representative supplies a letter of compliance, the emissions side is straightforward.18US EPA. Importing Canadian Vehicles NHTSA compliance still has to be confirmed separately, though for most Canadian-spec vehicles the differences are minor.
Returning Residents and Military Personnel
If you took a U.S.-spec vehicle abroad and are bringing it back, it enters duty-free as long as you can identify it, typically with a state registration card or a CBP Form 4455 issued before departure. Military members returning from extended overseas duty get a simplified entry process for personal effects, vehicles included.19eCFR. 19 CFR Part 148 – Personal Declarations and Exemptions Repairs abroad incidental to normal use aren’t dutiable, but modifications and accessories acquired overseas are.
Penalties for Getting It Wrong
A vehicle that enters without proper declarations, or that is misrepresented to dodge compliance, is subject to seizure. Once seized, it must be brought into compliance, exported, or destroyed.20U.S. Customs and Border Protection. CBP Seizes Illegal and Unsafe Motor Vehicle A vehicle previously smuggled in remains subject to seizure even in the hands of a later, innocent buyer.6U.S. Customs and Border Protection. Requirements for Importing a Personal Vehicle / Vehicle Parts
Bond forfeiture is a separate financial exposure. When an importer misses the conditions of a conformance bond, CBP demands the full bond amount. A petition to reduce or cancel the claim is available, but if no petition is filed or payment isn’t made, the full liquidated damages are enforced.21eCFR. 19 CFR Part 172 – Claims for Liquidated Damages; Penalties Secured by Bonds Filing a false statement in a petition for relief can trigger criminal prosecution.
State Titling After Federal Clearance
Federal clearance isn’t the last step. Every imported vehicle still needs a state title and registration before it can be driven legally. State DMVs generally require the HS-7 form stamped by CBP, a bill of sale, and proof of the vehicle’s identity. Initial titling fees typically fall between about $28 and $85 depending on the state.
Foreign-market vehicles often have identification numbers that don’t match the 17-digit U.S. VIN format, which creates friction at some DMVs. Some states handle it routinely; others require additional inspection or documentation. State emissions and safety inspections are separate from the federal process, and the rules vary. A vehicle cleared federally under the 25-year exemption may still have to pass a state inspection to register. Check the DMV requirements where you plan to register before assuming the federal clearance ends the process.
