Detailed Fine Structures & Calculations

CBP penalties are calculated based on the type and severity of violation:

Violation Type Legal Basis Minimum Fine Maximum Fine Typical Case Example
Undervaluation of Merchandise 19 CFR 171 20% of undervalued amount 40% of undervalued amount $1,000 item declared as $500 = $100-$200 fine
Failure to Declare Prohibited Item 19 U.S.C. 1592 Item seizure + $300 Item seizure + 300% value Undeclared fresh fruit worth $20 = seizure + $300 fine
False Statement on Form 18 U.S.C. 1001 $10,000 $250,000 + 5 years prison Claiming "nothing to declare" when carrying $2,000 in goods
Currency Non-Report 31 U.S.C. 5316 Seizure of all funds Seizure + criminal charges $12,000 not declared = full $12,000 seizure

Mitigating Factors:

  • First-Time Offense: May qualify for one-time warning instead of fine
  • Minimal Value: Items under $25 may be exempt from duty but still must be declared
