The Short Answer

Yes, federal law imposes civil penalties, seizure of prohibited items, and possible criminal prosecution for bringing prohibited items through U.S. customs.

What the Law Says

Federal law authorizes U.S. Customs and Border Protection (CBP) to assess penalties, seize prohibited goods, and refer cases for criminal prosecution when travelers or importers violate customs laws.

Under 19 U.S.C. § 1500, CBP has authority to appraise, classify, and liquidate entries — including determining whether merchandise is admissible. While § 1500 itself focuses on administrative procedures, it operates within a broader statutory framework (e.g., 19 U.S.C. §§ 1581–1597) that establishes penalties for violations such as importing prohibited or restricted articles without proper entry, declaration, or permits.

Civil penalties may be imposed for negligent or fraudulent misdeclaration, failure to declare, or importing prohibited items — up to the value of the merchandise or $10,000 per violation, whichever is greater. Criminal penalties apply for willful violations, including smuggling, with potential imprisonment up to 5 years and fines under Title 18.

Prohibited items include narcotics, counterfeit goods, certain agricultural products, unlicensed firearms, and goods violating intellectual property rights — each governed by specific statutes (e.g., 21 U.S.C. § 841 for drugs; 18 U.S.C. § 545 for smuggling).

Statutory Text

The Secretary of the Treasury shall prescribe regulations for the appraisement, classification, and liquidation of merchandise entered for consumption or warehouse, and for the assessment and collection of duties thereon.

What to Do

1

Declare all items truthfully on your CBP Form 6059-B (or electronically via CBP’s Mobile Passport Control or Global Entry app).

2

Research restrictions in advance using CBP’s website (cbp.gov) or contacting a licensed customs broker.

3

Obtain required permits or licenses for restricted items (e.g., FDA approval for food, USDA permits for plants).

4

If unsure whether an item is prohibited, consult CBP before travel or shipment.

5

If penalized, request a written explanation and consider filing a petition for relief (e.g., mitigation) with CBP within 30 days.
