The 25-year rule for importing cars, explained

What the 25-year rule allows

NHTSA lets a vehicle that is at least 25 years old be imported without meeting the federal motor vehicle safety standards it was never built to. Younger cars that weren't made for the US market generally can't be imported permanently unless they go through a separate, much harder compliance route.

The rule only covers federal safety standards. EPA emissions rules, customs paperwork and your state's title and registration rules all still apply on their own.

Why the build month matters

NHTSA counts 25 years from the car's actual manufacture date, not its model year or the year on the ad. A car built in March 2001 becomes eligible in March 2026, while one built in November 2001 has to wait until November 2026. Before you commit to a car, confirm the build date from its documents. We check it for every candidate. The Nissan Silvia S15 is a good example: its 1999–2002 production means cars become eligible one build month at a time through 2027.

Planning to buy a car early and store it until its birthday doesn't make early permanent import legal, and neither does calling a road car a "track car". Some vehicles do qualify through other lawful routes, but those have their own eligibility rules and use restrictions.

EPA's separate 21-year rule

EPA has its own age-based exemption. It generally covers vehicles at least 21 original-production years old in their original, unmodified configuration, and EPA calculates the age from production and import calendar years. Meeting it doesn't replace NHTSA's 25-year safety rule. You need both.

Engine swaps are where people get caught. EPA describes an acceptable replacement engine for its age-based provision as the same model and configuration as the original. A swapped car needs individual review before purchase or shipping, however old the body is.

Paperwork that comes with the car

• Ownership and Japanese export documents
• The purchase invoice and shipping documents
• NHTSA Form HS-7, declaring the car's status under the safety rules
• EPA Form 3520-1, where it applies
• Customs entry and clearance records

Keep every clearance record. You'll need them for the Texas title.

How to title an imported car in Texas

Federal rules decide whether the car can come in. Texas decides whether it can be titled and driven here. According to TxDMV, a vehicle imported from another country needs:

1. Proper import: it must meet, or be exempt from, the federal safety standards and all federal and state import requirements.
2. A passing safety inspection at a Texas-certified inspection station (you get a Vehicle Inspection Report). In Harris County and the other emissions counties it also needs an emissions inspection.
3. A law-enforcement VIN inspection by a trained auto theft investigator (Form VTR-68-A).
4. An application at your county tax office with Form 130-U, the HS-7 or other proof of customs clearance and safety compliance or exemption, the inspection reports, proof of insurance, the ownership document (with a certified English translation if it isn't in English) and the odometer reading where required.

TxDMV says to register within 30 days of the vehicle arriving in Texas. Fees and the 6.25% Texas motor vehicle tax are covered in our JDM import cost guide.
