Yes, you can import a car into the US, as long as it conforms to US safety and emissions standards. New or recent model automobiles must meet current standards, while cars over the age of 25 years may be exempt from these requirements. If you are unsure if your vehicle meets emissions standards, visit the website of the Environmental Protection Agency (EPA).
The total cost of shipping your car to America is determined by its size and weight, the distance, ports of departure and entry, shipping method and any additional services such as door-to-door services. Duties for vehicles entering the US are based on the price paid. They are typically 2.5% for automobiles, 25% for trucks, and 2.4% for motorcycles. Returning US residents may be able to use their $800 per person CBP allowance to offset the duty on a vehicle they purchased and used abroad.
If you are moving to the US on a short-term assignment, you may be able to bring your auto duty-free, as long as you keep the car in the US for less than 1 year.
