The utilization of erroneous HTS codes can lead to severe consequences, including monetary fines and the seizure of goods. The severity of these penalties is often dependent on factors such as the degree of negligence or intent on the part of the importer, the frequency of errors, and the nature of the misclassification.
Regardless of whether the importer is a novice or a seasoned international trader, it is imperative to ensure the accuracy of tariff classifications and import declarations. This guide will methodically elucidate how U.S. Customs and Border Protection (CBP) enforces violations of classification regulations, the criteria for assessing fines, and the available mechanisms for resolving penalties associated with erroneous HTS codes.

Why choosing the right HTS code matters
The correct use of Harmonized Tariff Schedule (HTS) codes isn’t just about following rules in international trade—it’s critical for your company’s bottom line, legal standing, reputation, and overall efficiency.
Your HTS Code Directly Impacts What You Pay
HTS codes dictate the exact amount of duty you owe on imported goods. Even a slight misstep in classification can result in significant cost differences. For example, if you accidentally classify a duty-free item under a code with high tariffs, your import costs will jump significantly, eating into your profits. Additionally, you may miss out on preferential duty rates available through trade agreements, which could put your products at a competitive disadvantage in the market.
You’re Legally Responsible as the Importer
U.S. Customs and Border Protection (CBP) relies on HTS codes to determine duties, collect trade statistics, and enforce various laws and regulations. As the Importer, you are legally responsible for ensuring those codes are accurate. Get them wrong, and your shipments could face delays or, even worse, your goods might be seized or destroyed. In some severe cases, misclassification can even be treated as fraud, which comes with hefty penalties and long-lasting repercussions.
Compliance Protects Your Reputation and Supply Chain
Consistently using incorrect HTS codes can label your business as high-risk with customs authorities. This often leads to more inspections, slower clearances, and higher operational costs in the long run. However, when you classify accurately, you achieve a smoother and more predictable shipping process. This helps with inventory planning and ensures customs clearance proceeds smoothly, ultimately leading to better customer service and a more reliable supply chain.
The Responsibility Is Always Yours
Even if your supplier or freight forwarder gives you HTS codes, the legal responsibility for their accuracy still rests squarely on your shoulders as the Importer. That’s why it’s non-negotiable to verify every single code before you submit your customs declaration. Being proactive about classification can save you from unnecessary expenses, regulatory issues, and potential damage to your business’s reputation.
Who Enforces Penalties for Incorrect Tariff Classification?
In the United States, U.S. Customs and Border Protection (CBP) is the primary agency responsible for enforcing compliance with tariff classification regulations. CBP has broad authority to review import declarations, verify the accuracy of Harmonized Tariff Schedule (HTS) codes, and take enforcement actions when misclassifications are found.
Penalties for incorrect tariff classification are not applied arbitrarily. CBP evaluates each case based on several factors, including the importer’s level of fault—whether the mistake was due to negligence, gross negligence, or intentional fraud—as well as any mitigating circumstances.
Importantly, liability is not limited to the importer alone. U.S. customs law prohibits any individual from aiding or abetting violations of customs regulations. That means customs brokers, freight forwarders, and even employees can be held accountable if they knowingly contribute to the misclassification of goods.
Even if an incorrect classification does not result in lost revenue for the government, it is still considered a violation of law. The act of misclassifying goods itself—intentionally or not—constitutes a breach of customs regulations and can lead to serious consequences.
What penalties can be imposed for using the wrong HTS code?
Using the wrong HTS code may result in various penalties, including:
- Financial penalties and fines: This is the most common penalty. CBP may impose fines of up to $10,000 per violation. Depending on the degree of negligence, fines may range from 0.5 to 8 times the value of the lost duties.CBP may also impose severe penalties for violations involving non-taxable, non-revenue goods.
- Customs clearance delays: Goods may be detained by customs, leading to clearance delays that impact supply chains and delivery timelines.
- Seizure or destruction of goods: If goods are incorrectly classified as restricted or prohibited, customs may seize or even destroy the goods.
- Future shipments may be subject to stricter scrutiny: Importers with a history of violations may face increased scrutiny from CBP for future shipments, resulting in more frequent inspections and potential delays.
- Potential legal issues and trade compliance violations: Serious classification errors, particularly those involving fraud, may lead to legal action, including criminal charges. For example, under the False Declaration Act, importers may face triple damages (three times the government’s losses) and substantial civil penalties. Whistleblowers who provide original information leading to the government successfully recovering losses may also be eligible for a reward of 15%-30% of the recovered amount.
- Damage to business reputation: Frequent violations may harm a company’s business reputation.
How to Ensure the Use of the Correct HTS Code
Using the correct Harmonized Tariff Schedule (HTS) code is essential for customs compliance and accurate duty assessment. Ensuring proper classification requires a careful, informed approach:
1. Understand Your Product Thoroughly
Start with a deep understanding of the product you’re importing. Consider its composition, function, intended use, manufacturing process, and any distinguishing features. These details are crucial for accurate classification.
2. Familiarize Yourself with the HTS Structure
The HTS system is organized into 99 chapters. Begin by identifying the chapter that best matches your product category, then progressively narrow down to the correct heading and subheading based on the specific details of your product.
3. Use the Official HTS Database
Refer to the official HTS database provided by the U.S. International Trade Commission (USITC). This resource allows you to search and verify tariff classifications, offering up-to-date and authoritative information.
4. Consult a Customs Professional
Licensed customs brokers and trade compliance specialists have the training and experience to help you navigate complex classifications. Many offer HTS code determination as a value-added service, helping reduce the risk of errors.
5. Request a Binding Ruling from CBP
If you’re uncertain about the correct HTS code for a product, consider requesting a binding ruling from U.S. Customs and Border Protection (CBP). This official decision provides legal certainty and protects you in the event of a customs audit.
6. Coordinate with Your Suppliers
It’s helpful to ask suppliers for the HS codes they commonly use. However, remember that the legal responsibility for correct classification falls on the importer. Always verify supplier-provided codes independently.
7. Stay Informed About HTS Updates
HTS codes are periodically revised to reflect changes in global trade and the evolution of technologies. Keeping current with these updates is crucial for maintaining compliance and ensuring accurate classification.
By following these best practices, importers can minimize the risk of misclassification, avoid costly penalties or shipment delays, and maintain a smooth and compliant import process.
