What the 25-year rule means
The NHTSA 25-year rule lets a vehicle that is 25 years old or older enter the United States without meeting the current Federal Motor Vehicle Safety Standards (FMVSS). For used-vehicle buyers, this single threshold decides most of the compliance work on an order.
If the model year is within 25 years, the vehicle generally must meet FMVSS, EPA emissions rules, and CBP entry formalities. That path is longer and depends on the exact specification, so confirm eligibility before you commit budget.
NHTSA and FMVSS compliance
NHTSA regulates vehicle safety through FMVSS. Vehicles at or beyond the 25-year mark are treated as exempt, which is why most classic and vintage imports clear without modification.
For newer used cars, compliance usually requires an Independent Commercial Importer (ICI) or a showing that the vehicle already meets FMVSS. Buyers should ask the supplier which path applies and keep the written confirmation with the order file. See the official guidance at NHTSA Importing a Vehicle.
EPA emissions requirements
The EPA sets federal emissions standards for imported vehicles. Vehicles 21 years or older are generally exempt from federal emissions certification, and heavy-duty vehicles above 8,500 lbs GVWR follow a different track.
EPA form 3520-1 documents the emissions basis at entry. The exact exemption that applies to your vehicle depends on model year and weight, so confirm the category rather than assuming.
Customs entry and duties
US Customs and Border Protection (CBP) handles the formal entry. Most passenger vehicles enter under HTS 8703 at a 2.5% duty rate, while other vehicle categories can differ, so verify the rate for your HS code.
Importers file entry through a licensed customs broker and present the DOT HS-7 and EPA 3520-1 forms. Broker fees and port handling are separate from the vehicle price and should be budgeted up front. CBP basics are at CBP Basic Import and Export.
Documents you will handle
| Document | Purpose | Who prepares it |
|---|---|---|
| Bill of sale | Proof of purchase and value | Seller |
| Export certificate / title | Ownership and export clearance | Origin jurisdiction |
| DOT Form HS-7 | States safety compliance basis | Importer / broker |
| EPA Form 3520-1 | States emissions basis | Importer / broker |
| Commercial invoice | Customs valuation | Seller |
What to confirm before you order
- Model year and exact 25-year eligibility date.
- Whether FMVSS or EPA exemptions apply to your vehicle.
- The HS code and the duty rate that goes with it.
- Which documents the supplier delivers and which the broker files.
- Port of entry and the broker who will file entry.
Common misunderstandings
- "Any used car can be imported." Only vehicles meeting an exemption or full FMVSS compliance clear.
- "State registration equals federal import." They are separate steps; federal entry comes first.
- "Duty is the only cost." Broker fees, port handling, and inland freight add up.
Frequently asked questions
Does the 25-year rule apply to trucks and motorcycles?
The age exemption applies to many vehicle types, but eligibility and any state rules vary. Confirm by VIN and model year.
Can I import a used car newer than 25 years?
Yes, but it must meet FMVSS through an ICI or another approved path. Expect more cost and lead time.
Do I pay duty on a used vehicle?
Usually yes, at the rate tied to the HS code. Ask your broker for the exact figure before ordering.
What forms does CBP require?
At minimum the DOT HS-7 and EPA 3520-1, plus the commercial invoice and ownership documents.
Is state registration separate from federal import?
Yes. Federal entry clears the border; the state handles titling and registration afterward.
Who confirms compliance for my order?
Your customs broker and the supplier should both confirm in writing. Keep those records with the shipment file.
Summary
The 25-year rule sets the compliance baseline for most used-vehicle imports. Newer vehicles need FMVSS and EPA steps that change cost and timing, so confirm the category early.
