CBP treats every undeclared agricultural item seriously. Here's the penalty structure, what to declare, and how to fill out CBP Form 6059B without a mistake.
🚨 The Most Common Mistake: "It's Sealed, So It's Fine"
Commercially packaged fruit, seeds, or meat products still must be declared — sealed packaging doesn't exempt them. CBP officials are explicit: all agriculture items must be declared, even a free apple from your flight. The fix: declare every food, plant, or animal item on CBP Form 6059B, regardless of packaging.
| Violation | Penalty |
|---|---|
| Undeclared agricultural item, first offense (non-commercial) | Up to $300–$1,000 |
| Undeclared dutiable goods (discovered by officer) | 3× the duty owed (min $50), or domestic value, whichever is lower |
| Duty-free item that should've been declared | 1–5% of domestic value ($50 floor, $1,000 ceiling) |
| Undeclared cash over $10,000 | Seizure of entire amount, not just the excess; criminal referral possible |
A customs violation can also trigger revocation of Global Entry, NEXUS, or TSA PreCheck — even for a single incident — separate from the monetary fine.
| Item | Allowance |
|---|---|
| Personal exemption (most countries) | $800 per returning US resident |
| Personal exemption (US insular possessions) | $1,600 (Guam, USVI, American Samoa) |
| Alcohol (Canadians entering US) | 1 litre regardless of stay duration, personal use only |
Exceeding your exemption means duty applies only to the amount over the limit — unlike some countries where the entire value becomes dutiable.
❓ Frequently Asked Questions — United States Customs
Do I need to declare a sealed granola bar from my flight?
Yes. All food must be declared regardless of packaging, even a free airline snack. CBP treats undeclared agricultural items seriously — first-offense civil penalties for non-commercial quantities can reach $1,000.
What happens if I forget to declare a $2,000 watch?
The item can be confiscated and you face a penalty up to its full domestic value on top of losing it — even if you would have owed little or no duty. Honest declaration, even of high-value items, avoids this entirely.
Is there a fee to declare cash over $10,000?
No. There's no tax or fee for carrying large sums — CBP simply requires a record via FinCEN Form 105. The serious consequences only apply if you fail to report it, which can mean losing the entire amount, not just the excess.
Can a customs violation affect my Global Entry membership?
Yes. CBP has revoked Global Entry memberships over single incidents of undeclared items, sometimes paired with a separate $500 civil penalty. This is independent of any agricultural or duty fine.
What's the difference between a civil penalty and criminal charges at customs?
Civil penalties apply when CBP sees carelessness or corner-cutting — fines and confiscation. Criminal charges apply when evidence points to deliberate fraud, concealment, or prohibited items like drugs or weapons, and can carry sentences up to 20 years.
