Incorrect tariff classification is one of the most common issues identified during customs audits and post entry reviews. When goods are declared under an incorrect HS or HTS code, customs authorities may reassess duties and determine whether the incorrect information constitutes a violation of U.S. customs law.

In the United States, civil penalties for false statements or material omissions in import declarations are governed by 19 U.S.C. §1592. The law applies when merchandise is entered into the United States using materially false information or material omissions that affect classification, valuation, duty liability, or admissibility.

The statute establishes three levels of culpability:

• Negligence
• Gross negligence
• Fraud

Each level carries different legal standards and maximum penalties.

HS and HTS Codes in Import Declarations

Tariff classification determines how imported goods are treated by customs authorities. The Harmonized System provides the international framework used to classify goods in global trade. National tariff schedules expand the system to apply country specific duty rates and trade rules.

In the United States, this system is implemented through the Harmonized Tariff Schedule of the United States. The first six digits correspond to the international Harmonized System, while additional digits apply U.S. duty rates and regulatory measures.

Customs authorities rely on these classifications to determine:

• Applicable duty rates
• Import restrictions and regulatory requirements
• Eligibility for trade preference programs

If the declared classification is incorrect, the entry may be considered a violation if the importer provided inaccurate information to customs authorities.

Civil Penalties Under U.S. Customs Law

Under 19 U.S.C. §1592, the maximum civil penalty depends on the level of culpability associated with the violation.

Violation Level	Legal Standard	Maximum Penalty
Negligence	Failure to exercise reasonable care	Lesser of the domestic value or 2× the loss of duties, taxes, and fees. If no duty loss: up to 20% of the dutiable value.
Gross Negligence	Actual knowledge or wanton disregard of legal obligations	Lesser of the domestic value or 4× the loss of duties, taxes, and fees. If no duty loss: up to 40% of the dutiable value.
Fraud	Intentional false statements or omissions	Up to the domestic value of the merchandise.

The severity of the penalty increases with the level of culpability.

Domestic value generally refers to the price at which such or similar property is freely offered for sale at the time and place of appraisal in the ordinary course of trade.

Negligence, 19 U.S.C. §1592(c)(3)

Negligence is the lowest level of culpability under the statute. It occurs when an importer fails to exercise reasonable care in providing information to customs authorities.

Examples of circumstances that may lead to a negligence finding include:

• Using supplier provided HS codes without verifying the classification
• Assigning classifications without reviewing product specifications
• Maintaining incomplete product descriptions in internal systems
• Failing to review classifications after tariff schedule updates

Maximum statutory penalty

Under 19 U.S.C. §1592(c)(3):

If duties were underpaid:

• Maximum penalty is the lesser of
  • the domestic value of the merchandise, or
  • two times the lawful duties, taxes, and fees of which the United States is or may be deprived

If the violation did not affect the assessment of duties:

• Maximum penalty is 20 percent of the dutiable value of the merchandise.

Gross Negligence, 19 U.S.C. §1592(c)(2)

Gross negligence represents a higher level of culpability than negligence. Under the statute, gross negligence is treated as a distinct category with higher maximum penalties.

Situations that may support a gross negligence finding include:

• Continuing to use an incorrect classification after internal warnings
• Ignoring compliance reviews that identified classification errors
• Maintaining inadequate procedures for determining tariff classifications
• Repeated import entries using a classification known to be incorrect

Maximum statutory penalty

Under 19 U.S.C. §1592(c)(2):

If duties were underpaid:

• Maximum penalty is the lesser of
  • the domestic value of the merchandise, or
  • four times the lawful duties, taxes, and fees of which the United States is or may be deprived

If the violation did not affect the assessment of duties:

• Maximum penalty is 40 percent of the dutiable value of the merchandise.

Fraud, 19 U.S.C. §1592(c)(1)

Fraud is the most serious violation category under 19 U.S.C. §1592. Fraud involves intentional false statements or omissions in connection with an import entry.

Examples of conduct that may support a fraud finding include:

• Intentionally declaring goods under a lower duty tariff classification
• Providing false product descriptions to justify a classification
• Submitting falsified technical documentation related to imported goods
• Coordinating with suppliers to misrepresent product characteristics

Maximum statutory penalty

Under 19 U.S.C. §1592(c)(1):

• The maximum civil penalty for fraud is an amount not to exceed the domestic value of the merchandise.

Prior Disclosure and Reduced Penalty Caps

19 U.S.C. §1592 includes a prior disclosure provision. When a person discloses the circumstances of a violation before, or without knowledge of, the commencement of a formal investigation of that violation, the maximum monetary penalty is capped under 19 U.S.C. §1592(c)(4).

Under 19 U.S.C. §1592(c)(4), the monetary penalty shall not exceed:

If the violation resulted from negligence or gross negligence:

• The interest, computed from the date of liquidation, on the amount of duties, taxes, and fees of which the United States is or may be deprived, provided the person tenders the unpaid amounts at the time of disclosure or within the time specified by customs.

If the violation resulted from fraud:

• One times the lawful duties, taxes, and fees of which the United States is or may be deprived, provided the person tenders the unpaid amounts at the time of disclosure or within the time specified by customs; or
• If the violation did not affect the assessment of duties, taxes, and fees, 10 percent of the dutiable value of the merchandise.

Why Accurate Classification Matters

HS and HTS codes determine duty rates, regulatory requirements, and eligibility for trade preference programs. Incorrect classification can result in duty reassessments and potential penalties under U.S. customs law.

The level of potential civil penalty exposure depends on whether customs determines the violation involved negligence, gross negligence, or fraud. Importers that maintain documented classification procedures, accurate product data, and effective internal controls are better positioned to reduce the risk of classification errors and to respond effectively during customs reviews.
