Vehicle and Transportation Imports into the United States: CBP Tariffs, Compliance, Detentions, and Enforcement
Your vehicle has arrived at a U.S. port. You expected the usual customs clearance process. Instead, the United States Customs and Border Protection (“CBP”) places the shipment on hold and starts asking questions. Maybe CBP wants documentation supporting the vehicle’s country of origin. It may also be questioning the declared value, tariff classification, or United States-Mexico-Canada (“USMCA”) treatment. Or perhaps CBP is asking you to explain information provided by your manufacturer or supplier.
Your vehicle is still sitting at the port. Your inventory is tied up. Your customer may be waiting. And you now have to determine what CBP’s questions mean and what could happen if the agency is not satisfied with the information provided.
If you import motor vehicles into the United States, a problem that initially looks like a routine customs issue can become much more serious.
That can happen when CBP questions an entry, places a vehicles on hold, requests supporting documentation, or begins an enforcement action.
The tariff rules make the analysis even more complicated for some importers. Canadian vehicle importers, for example, must account for existing tariff measures, the Section 338 measures discussed below, and the recently announced potential increase in tariffs on Canadian cars, trucks, automotive parts, and steel. They must also determine which ordinary customs and regulatory requirements apply to the particular vehicle being imported.
A problem that begins as a classification, origin, valuation, documentation, or regulatory issue can eventually become a CBP enforcement matter.
Importing a vehicle can raise questions about origin, USMCA treatment, classification, valuation, Section 232 tariffs, and federal vehicle requirements. Those issues can also lead to detention, seizure additional duties, or other enforcement action. The goal here is to explain where those problems tend to arise and what an importer should consider when CBP begins asking questions.
Vehicle and Transportation Import: Cars, Motorcycles, Boats, E-Bikes, and More.
Motor-vehicle imports can involve much more than passenger automobiles. Depending on the product and its intended use, importers may encounter different customs and regulatory requirements involving motorcycles, recreational vehicles, commercial vehicles, certain off-road vehicles, electric vehicles, and vehicle parts and components. Other transportation-related products, such as boats, e-bikes, trailers, and industrial equipment, may be subject to separate classification and regulatory frameworks and should not automatically be treated as “motor vehicles.”
The requirements are not necessarily the same from one vehicle or product category to another. The proper analysis depends on the specific product, its specifications, its country of origin, how it was manufactured, and the circumstances of the importation.
Common Reasons CBP Holds or Seizes Imported Vehicles.
Tariffs are only one part of the picture. Motor-vehicle imports can attract scrutiny when CBP has questions about the information reported on an entry or about whether the vehicle satisfies applicable federal requirements. CBP’s questions may involve several different issues:
Country of Origin Disputes and USMCA Claims
Country of origin can be one of the most difficult issues in vehicle imports. For vehicles claiming USMCA preferential treatment, the analysis can involve rules of origin, regional value content, and other requirements. If you claim USMCA treatment, your certificate of origin is important, but it may not be the only information relevant to the claim. CBP may also look at the vehicle’s production, sourcing, and other underlying information.
The importer may not have all of the information needed to independently establish the vehicle’s origin. Relevant information may come from the manufacturer or supplier, including production records, sourcing information, and certifications.
If CBP later determines that a preferential claim was not supported, the importer can face additional duty liability and, depending on the circumstances, potential penalty exposure. That does not necessarily relieve the importer of its obligations to CBP simply because the information came from a foreign supplier.
Section 232 Tariffs on Steel and Aluminum
Section 232 measures can also affect vehicle and vehicle-component imports. Whether Section 232 applies depends on the merchandise being imported, its tariff classification, the particular Section 232 measure at issue, and the entry documentation.
If you’re importing vehicles or components containing steel or aluminium into the U.S., you need to determine whether Section 232 applies to your particular merchandise and how the applicable measure interacts with other tariff provisions.
This interaction between these tariff provisions can be especially important for Canadian automotive products
NHTSA, EPA, and Vehicle Compliance
CBP also works with other federal agencies in administering requirements applicable to imported vehicles. National Highway Traffic Safety Administration (“NHTSA”) regulates federal motor vehicle safety requirements, while Environmental Protection Agency (“EPA”) administers federal emissions requirements for covered vehicles and engines.
A vehicle that does not satisfy applicable federal requirements may face problems at the border even if the customs entry itself is otherwise properly prepared. Depending on the circumstances, an importer may face detention, exclusion, exportation, or other enforcement consequences.
This matters especially when the vehicle was manufactured for a foreign market. Compliance with the laws of the country where the vehicle was manufactured does not necessarily establish compliance with U.S. requirements.
Odometer Fraud and Title Issues
Odometer fraud and documentation problems present a different type of risk. Questions concerning an imported vehicle’s mileage, title history, identification information, or supporting documentation can become significantly more serious when CBP or another federal agency suspects that information has been altered or misrepresented.
The consequences may extend beyond customs duties and may involve other federal or state requirements.
If information concerning a vehicle’s mileage, identification, title history, or other documentation is inaccurate or appears inconsistent, the issue may require more than simply correcting an entry.
How a Wrong HTS Code Creates Bigger Problems Than You Expect
Every imported vehicle or vehicle component must be properly classified under the Harmonized Tariff Schedule of the United States (“HTSUS”).
Classification can depend on characteristics such as the type of vehicle, engine or motor specifications, propulsion system, passenger or cargo capacity, and other product-specific characteristics. Small differences in the merchandise can sometimes result in materially different tariff treatment. Classification also matters because it can determine whether additional tariff measures apply. An incorrect classification can therefore affect more than the base customs duty.
As discussed in the firm's prior article on Section 232 vs. Section 301 tariffs, classification is one of the first things an importer should get right when determining its tariff obligations.
Customs Valuation Disputes
CBP also examines the value reported for imported vehicles. Valuation questions can arise in related-party transactions, unusual pricing arrangements, or situations where the declared value does not comply with the applicable customs valuation rules.
For used vehicles, valuation disputes may arise when CBP questions the declared price or supporting documentation. For new vehicles and related products, valuation issues can also involve assists or other amounts that may need to be considered in determining the customs value.
An undervaluation can result in unpaid duties and, depending on the facts, potential penalty exposure.
If CBP questions your declared value, the issue may involve more than whether the purchase price appears reasonable. The applicable customs valuation rules and the circumstances of the transaction must be considered.
Anti-Dumping and Countervailing Duty Orders
Certain vehicle components and other automotive products may also be covered by antidumping or countervailing duty orders. Determining whether an order applies can be difficult because the answer may depend on the precise merchandise description, country of origin, manufacturer or exporter, and the language of the particular order.
As discussed in the firm's prior article on transshipment enforcement, attempting to disguise the actual country of origin or route merchandise through another country to avoid applicable trade measures can create substantially greater enforcement exposure.
The Section 338 and Canadian Imports: What Vehicle Importers Need to Know
On July 20, 2026, President Trump issued a proclamation under Section 338 of the Tariff Act of 1930, imposing an additional 50% ad valorem duty on certain products of Canada identified in the proclamation. The proclamation was issued in response to what the President determined was discriminatory treatment of U.S. motor vehicles and auto parts by Canada.
The Section 338 measures did not, however, result in a 50% tariff on Canadian imported vehicles. The July 20 proclamation identified the covered products through the HTSUS and its annexes and originally made the additional duties effective August 19, 2026. On August 18, however, the President suspended those duties for three days while negotiations with Canada continued. The duties therefore became effective on August 22, 2026.
For vehicle importers, the distinction is important. The Section 338 action should not be described as a blanket 50% tariff on Canadian passenger vehicles. The additional duty applies only to Canadian products identified in the applicable HTSUS provisions and annexes. Moreover, the proclamation excludes article subject to Section 232. Rather, the Section 338 measures apply to specified Canadian products identified under the applicable HTSUS provisions, while Canadian automobiles and automotive products remained subject to the separate tariff measures applicable to those products.
On August 24, 2026, President Trump announced through a social-media post that tariffs on Canadian cars, trucks, automotive parts, and steel would be increased to 50% beginning January 1, 2027. That announcement is not, by itself, an implementing tariff provision. As of the date of this article, the precise HTSUS provisions and mechanics for the proposed January 1, 2027 increase have not been provided. Importers should therefore monitor subsequent presidential action, HTSUS changes, and CBP guidance before determining how calculating the tariff treatment that would apply to a particular importation.
The interaction between the proposed January 1, 2027 tariff increase, existing automotive tariffs, Section 232 measures, and any applicable USMCA treatment will need to be evaluated under the implementing provisions in effect at that time. If implemented as announced, the increase could significantly change the tariff cost of importing Canadian vehicles and automotive products. Importers may need to revisit pricing, sourcing, and other aspects of their import arrangements.
Received a CF-28 or Seizure Notice on a Vehicle Import? Here’s What It Means.
What happens next depends on the issue CBP is investigating. A request or notice from CBP should not be treated as routine paperwork simply because the vehicle has not yet been seized.
A CF-28 Request for Information may be used when CBP requests documentation or information concerning an entry. If you receive a CF-28, CBP may be questioning your classification, valuation, country of origin, preferential treatment, or another aspect of your entry. The significance of the request depends on what CBP is asking and why.
A CBP seizure notice is more serious. If CBP seizes your vehicle, you are no longer dealing with a shipment that has been delayed. Your vehicle is in government custody. Applicable deadlines may arise. The matter may also develop into a forfeiture or other enforcement proceeding.
Section 592 penalty proceedings may also arise when CBP determines that material false statements or omissions were made in connection with an entry. The potential liability can be substantial, particularly when the merchandise is high-value or the same issue affects multiple entries.
When It Makes Sense to Bring in Trade Compliance and Enforcement Counsel
You do not have to wait until CBP seizes a vehicle before involving counsel. If you are unsure about the classification, origin, valuation, tariff treatment, or supporting documentation for an import, it can make sense to have the issue reviewed before CBP raises it.
Likewise, when CBP has already sent a CF-28, issued a detention or seizure notice, or otherwise questioned an entry, early legal review can help determine what the government is actually asking, what information should be assembled, and what legal issues may be developing.
The importer of record is generally responsible for the accuracy of the information submitted to CBP. A manufacturer, supplier, customs broker, or freight forwarder may provide information or services, but that does not necessarily relieve the importer of its own obligations to CBP. At the same time, the circumstances surrounding that reliance may be relevant to the importer’s legal position if CBP later alleges a violation.
A customs broker can be an essential part of an importer’s compliance team, but a CBP enforcement matter can raise legal questions that go beyond the preparation and transmission of an entry.
A vehicle import can involve customs law, tariff measures, federal vehicle requirements, and CBP enforcement at the same time. When those issues overlap, the question is no longer simply whether an entry can be filed.
When that happens, the issue is no longer simply whether an entry can be filed. You may need to determine what CBP is asking for, what you are required to disclose, and whether there is any potential liability beyond the immediate shipment.
You should consider speaking with counsel if:
CBP issues a CF-28 or other request that could lead to additional duties or enforcement;
A vehicle or shipment is detained or seized;
CBP questions your classification, valuation, country of origin, or preferential tariff claim;
You discover a potential compliance problem involving prior entries;
You are considering whether a voluntary disclosure or another corrective submission is appropriate; or
You want to understand your potential exposure before continuing an existing import program.
For a business importing motor vehicles, the real risk is not simply paying the wrong amount of duty on one shipment. A classification, valuation, origin, documentation, or regulatory problem can affect more than one entry and may create financial consequences long after the vehicle has been sold.
If your company imports vehicles or vehicle-related products into the United States, including cars, motorcycles, trucks, recreational vehicles, golf carts, electric vehicles, or vehicle components and has received any communication from CBP such as a CF-28, a CF-29, a detention notice, a seizure notice, or if you have questions about the tariffs, classification, country of origin, valuation, or compliance of an existing vehicle import program, contact us to discuss the situation confidentially.
-
Yes. Depending on the circumstances, CBP may seize a vehicle when it believes there has been a violation of customs laws or other applicable federal requirements.
-
A detention means CBP is holding the vehicle while the agency addresses a particular issue. A detention does not necessarily mean the vehicle will be seized, but it should be taken seriously.
-
A CF-28 is a Request for Information from CBP concerning an entry. It may involve questions about classification, valuation, country of origin, tariff treatment, or other entry information.
-
Yes. CBP may review the claimed country of origin, including information supporting a USMCA preferential tariff claim.
-
Potentially. As the importer of record, you have obligations concerning the accuracy of your customs entries. The circumstances surrounding the information provided by your supplier may also be relevant to the matter.
-
Yes. CBP may question the declared value of a vehicle if the agency believes the value does not comply with applicable customs valuation requirements.
-
An incorrect classification can result in additional duties and, depending on the circumstances, potential penalty exposure. The financial impact can be greater when additional tariff measures are involved.
-
No. USMCA qualification does not necessarily resolve every tariff issue. Other tariff measures may still apply depending on the vehicle, its classification, country of origin, and the specific tariff provision at issue.
-
Yes. Imported vehicles may be subject to federal safety and emissions requirements administered by agencies including NHTSA and EPA. Compliance with the laws of another country does not necessarily establish compliance with U.S. requirements.
-
You should consider speaking with a trade compliance and enforcement counsel when CBP questions your entry, your vehicle is detained seized, or you have concerns about classification, valuation, country of origin, tariff treatment, or compliance.
