Understanding Car Import Tariffs and Customs Duty in the US

The short answer

US customs car import duty is a percentage of the vehicle's dutiable value, which is usually the price paid for it. The rate comes from the Harmonized Tariff Schedule of the United States (HTSUS), which classifies goods by type. For many years the base rate was 2.5 percent for passenger cars and 25 percent for light trucks, the higher truck rate often called the "chicken tax." Since 2025, additional tariffs on imported vehicles and some parts have been added on top of or in place of those base rates, and the effective rate now varies by country of origin and by trade agreement. These rates have changed several times and may change again, so check the current tariff schedule or ask a licensed customs broker before you budget for a specific car.

What a tariff is and how it differs from other import costs

"Tariff" and "customs duty" mean essentially the same thing: a tax collected by US Customs and Border Protection (CBP) when goods enter the country. Several other costs are often grouped together with duty, but they are separate:

Customs duty: the percentage-based tax set by the tariff schedule and any additional tariff measures. Customs processing fees: smaller fees charged on formal entries, such as the Merchandise Processing Fee and, for ocean shipments, the Harbor Maintenance Fee. Gas guzzler tax: a federal excise tax on certain new passenger cars with low fuel economy. Whether it applies depends on the vehicle. Shipping, insurance and port charges: paid to carriers and terminals, not to the government. Customs broker fees: optional, and paid only if you hire a broker to file the entry for you. State costs: sales or use tax, title and registration, charged by your state after import.

What determines how much duty you pay

Vehicle classification

The HTSUS code assigned to the vehicle sets the base rate. Passenger cars, light trucks, motorcycles and commercial vehicles fall under different headings. Classification follows the vehicle's design and intended use, not its marketing name. The large gap between the historical car and light-truck rates is why some pickups and vans are classified differently from what buyers expect, and why disputes over how a vehicle should be classified come up.

Country of origin

Duty depends on where the vehicle was manufactured, not where you bought it or where it was shipped from. A car built in one country and sold in another keeps its original country of origin for customs purposes. This matters more now that country-specific tariff arrangements are in force.

Trade agreements

Vehicles that meet the rules of origin under a trade agreement may receive a reduced or zero rate. The most relevant agreement for cars is the United States-Mexico-Canada Agreement (USMCA). Qualifying is not automatic just because a car was assembled in Canada or Mexico. The rules look at how much of the vehicle's content comes from the region, and the importer has to be able to support the claim.

Dutiable value

Duty is normally calculated on the transaction value, meaning the price actually paid or payable. A bill of sale showing the real purchase price is central to the entry. If CBP doubts a declared value, it can determine the value by other methods, and undervaluing a vehicle can lead to penalties.

Exemptions and special cases

Some imports are treated differently. Examples include certain US-made vehicles being returned, vehicles brought in temporarily by nonresidents, and vehicles imported by returning residents or military and government personnel under specific conditions. Each has its own requirements, and none applies just because a vehicle is used or personally owned. Confirm whether your situation qualifies before you count on a reduced rate.

Duty is not the same as eligibility

This is where many imports go wrong. CBP collects the duty, but whether the vehicle can legally enter and be registered also depends on two other federal agencies:

Safety standards: the Department of Transportation, through NHTSA, requires vehicles to meet the Federal Motor Vehicle Safety Standards (FMVSS). The DOT declaration for this is Form HS-7. Emissions compliance: the Environmental Protection Agency requires vehicles to meet federal emissions rules. The EPA declaration is Form 3520-1. Some states, notably California, have stricter emissions requirements of their own.

A car built to US market specification normally carries manufacturer labels certifying that it meets both sets of standards, which makes the import much simpler. A car built for another market usually lacks those certifications even if it looks identical to a US model. Lighting, bumpers, crash structures, emissions equipment and labeling can all differ by market specification, and the same model can differ between generations, model years and regions.

Vehicles that do not conform generally have to be brought into compliance by a DOT Registered Importer, and for emissions by an appropriate EPA-recognized process. This can be expensive and is not possible for every vehicle. The main exceptions are based on age. Vehicles at least 25 years old are exempt from FMVSS requirements, and vehicles at least 21 years old in original, unmodified configuration are generally exempt from EPA requirements. Age is counted from the date of manufacture, so a car of the right model year may still be a few months too young.

Import documentation you can expect to need

The exact paperwork varies with the vehicle and how it is shipped, but a typical personal vehicle import involves:

Bill of lading or other shipping document from the carrier. Bill of sale or commercial invoice showing the purchase price. Foreign title or registration as proof of ownership. CBP entry documents, including the entry summary on which duty is declared. DOT Form HS-7 declaring the vehicle's safety status or exemption. EPA Form 3520-1 declaring the vehicle's emissions status or exemption. Compliance paperwork from a Registered Importer, if the vehicle is nonconforming.

How customs clearance works in practice

When the vehicle arrives, the importer or their customs broker files the entry with CBP, declares the classification, origin and value, and submits the DOT and EPA declarations. CBP reviews the entry, may inspect the vehicle, and collects the duty and fees. Once the vehicle is released, you take the customs paperwork to your state motor vehicle agency to title and register it. Many first-time importers hire a customs broker, especially for higher-value vehicles or where classification or origin is not obvious. Hiring one is not mandatory for a personal import.

Exports from the US have their own process. Vehicles leaving the country generally have to be presented to CBP with proof of ownership before departure, and the destination country then applies its own tariffs and eligibility rules.

Practical takeaways before you buy

Identify the vehicle's HTSUS classification and country of origin, then check the current duty rate, including any additional tariffs that apply. Find out whether the vehicle was built to US market specification. If not, check whether it meets an age exemption or can realistically be brought into compliance. Budget for fees, shipping, broker costs, state taxes and any possible gas guzzler tax as well as the duty. Keep accurate purchase and ownership records, because the declared value and proof of title underpin the whole entry. If anything is uncertain, especially for a vehicle that has not been imported before, get a broker's assessment before you commit to the purchase.
