The tax to import a car from Japan to the US starts with a 2.5% federal customs duty on passenger cars, plus a 25% Section 232 tariff on anything built in the last 25 years, small processing and harbor fees, a possible gas guzzler tax on low-MPG vehicles, and state sales or use tax when you register. On a $20,000 passenger car at least 25 years old, the federal bill lands around $594 before any gas guzzler charge. On the same car if it is newer, add roughly $5,000 for the Section 232 tariff.
The 25% Section 232 Tariff Is the Big One
The single largest cost for most importers is the Section 232 national-security tariff that took effect April 3, 2025. Under Presidential Proclamation 10908, imported automobiles carry a 25% ad valorem tariff on top of any existing customs duty, fees, and charges.1Federal Register. Adjusting Imports of Automobiles and Automobile Parts Into the United States On a $20,000 sedan, that is $5,000 by itself.
Vehicles manufactured in a year at least 25 years before the year of entry are exempt.2U.S. Customs and Border Protection. Section 232 Additional FAQs – Automobiles and Auto Parts For entries filed in 2026, that covers anything built in 2001 or earlier. A 1999 Skyline GT-R pays no Section 232 duty; a 2005 model pays the full 25%. Age is the biggest single variable in your landed cost.
Japan and the U.S. have negotiated a bilateral arrangement that may modify the effective Section 232 rate on Japanese-origin vehicles. Because the rate is moving, confirm the number in effect on your entry date with CBP guidance or a licensed customs broker.
The 2.5% Base Duty, and the 25% Light-Truck Trap
Every imported vehicle also owes a standard duty set by the Harmonized Tariff Schedule, Chapter 87. Passenger cars fall under heading 8703 at 2.5% of the transaction value.3United States International Trade Commission. Harmonized Tariff Schedule of the United States – Chapter 87 On $20,000, that is $500.
Light trucks, vans, and certain utility vehicles are a different story. They fall under the 25% “Chicken Tax” duty that has applied since 1964. Classification depends on the vehicle’s structural design and intended use, not on how you personally plan to drive it. A misclassification can cost thousands, so confirm the correct HTS subheading before you ship. Vehicles taxed at the light-truck rate are not subject to the gas guzzler tax below.
Gas Guzzler Tax on Thirsty Passenger Cars
Passenger cars rated below 22.5 combined MPG owe a federal gas guzzler tax under 26 U.S.C. § 4064. The scale runs from $1,000 for a car between 21.5 and 22.5 MPG up to $7,700 for a car below 12.5 MPG.4Office of the Law Revision Counsel. 26 USC 4064 – Gas Guzzler Tax Plenty of Japanese performance cars from the 1990s and early 2000s land inside that table, so look up your model’s EPA-equivalent fuel economy before you commit to a purchase.
The tax applies only to passenger automobiles. Trucks and SUVs classified under the light-truck heading avoid it, but they pay the 25% Chicken Tax duty instead.
Processing and Harbor Fees
CBP charges a Merchandise Processing Fee on every formal entry. For fiscal year 2026, the rate is 0.3464% of customs value, with a floor of $33.58 and a ceiling of $651.50 per entry.5Federal Register. Customs User Fees To Be Adjusted for Inflation in Fiscal Year 2026 On a $20,000 car, that is roughly $69. Paper filings add a $4.03 surcharge.6U.S. Customs and Border Protection.

Any vehicle arriving by ship also owes the Harbor Maintenance Fee at 0.125% of declared value.7eCFR. 19 CFR 24.24 – Harbor Maintenance Fee Another $25 on a $20,000 car. Small on their own, they stack.
What CBP Charges the Percentages Against
Every percentage above runs against the vehicle’s transaction value, defined by federal law as the price you actually paid or agreed to pay when the car was sold for export to the United States.8Office of the Law Revision Counsel. 19 U.S. Code 1401a – Value International ocean freight and marine insurance from Japan to the U.S. port are excluded from that figure. The statute does add certain items when they apply: packing costs you paid, any buying commission, and royalties or license fees tied to the sale.
Your commercial invoice or auction receipt is the primary proof. If CBP thinks the declared price looks low, they can request more documentation or appraise the vehicle themselves. Keep the original purchase records, wire confirmations, and auction screenshots.
State Sales or Use Tax at Registration
Federal duty and tariffs are only the first bill. When you register the car with your state DMV, most states charge sales or use tax on the vehicle’s full value. Rates run from roughly 4% to over 10% depending on where you live, and no state gives a credit for customs duties paid to the federal government or for taxes paid in Japan. On a $20,000 import, expect $800 to $2,000 in state tax alone.
Many states also require a VIN verification for a vehicle that has never been titled domestically. A mobile VIN inspection usually runs $25 to $125. Title and registration fees are separate again and vary widely by state.
Sample Total on a $20,000 Car
Here is how the federal side breaks down for a $20,000 Japanese passenger car entering in 2026, assuming it qualifies for the Section 232 age exemption:
- Base customs duty at 2.5%: $500
- Section 232 tariff: $0, since the car is 25 or more years old
- Merchandise Processing Fee at 0.3464%: about $69
- Harbor Maintenance Fee at 0.125%: $25
- Gas guzzler tax: $0 to $7,700 depending on fuel economy
- Federal subtotal before any gas guzzler charge: about $594
If the same car is newer than 25 years, add the Section 232 tariff on top. At the general proclamation rate that is another $5,000 on a $20,000 vehicle, though the U.S.–Japan bilateral arrangement may reduce that figure by the time you file. State sales tax, shipping, and any federal safety-compliance work for a non-conforming vehicle sit on top of everything above. Two numbers move the total more than any others: the age of the car, which controls Section 232, and the fuel economy, which controls gas guzzler exposure. Pin down both before you buy.
