U.S. customs rules for travelers require you to declare everything you’re bringing into the country on CBP Form 6059B, including any currency over $10,000, all food and agricultural products, and the total value of goods purchased or received abroad. Most travelers owe no duty because the first $800 in goods is exempt, but the rules on what must be declared are strict, and the penalties for skipping a declaration can equal or exceed the value of the item itself.
What You Have to Declare
You fill out CBP Declaration Form 6059B before you arrive, and one form covers your entire immediate family traveling together.1U.S. Customs and Border Protection. CBP Traveler Entry Forms The form asks about the value of goods you’re bringing in, whether you visited a farm, whether you’re carrying food, plants, or animal products, and whether you have more than $10,000 in currency or monetary instruments.
Everything you purchased abroad or received as a gift has to appear on that form, even if it falls within your duty-free allowance. Gifts you carry with you count against your personal exemption rather than getting a separate allowance, and gifts intended for business or resale can’t be included in the exemption at all.2U.S. Customs and Border Protection.

Currency Over $10,000
If you’re carrying more than $10,000 in currency or monetary instruments, you must file FinCEN Form 105 with a customs officer at your port of entry or departure.3Office of the Law Revision Counsel. 31 U.S. Code 5316 – Reports on Exporting and Importing Monetary Instruments The threshold applies to the combined total a family traveling together with pooled funds is carrying, not per person.
“Monetary instruments” is broader than cash. It includes traveler’s checks, money orders, cashier’s checks, personal checks endorsed without restriction or made out to a fictitious payee, bearer securities, and incomplete instruments signed but with the payee’s name left blank. Credit cards, prepaid cards, Bitcoin and other virtual currencies, and precious-metal coins do not count.4U.S. Customs and Border Protection. Currency / Monetary Instruments – Definition of Negotiable Monetary Instruments for Currency Reporting Requirements
You don’t owe tax on the money just for carrying it. The reporting requirement exists regardless of whether the funds are legally earned. Failing to report can result in a civil fine of up to $500,000, criminal imprisonment of up to ten years, and seizure of the currency itself.5Financial Crimes Enforcement Network. FinCEN Form 105 Intentionally concealing currency to avoid reporting is a separate offense under the bulk cash smuggling statute, which carries up to five years in prison plus forfeiture.6Office of the Law Revision Counsel. 31 U.S. Code 5332 – Bulk Cash Smuggling Into or Out of the United States
Food, Plants, and Agricultural Items
You must declare all food, plants, seeds, soil, animals, and animal products, including items that don’t seem risky like soup mixes and herbal teas. CBP agriculture specialists inspect declared items and decide whether they can enter. Many fresh and dried meats are prohibited because of diseases like foot-and-mouth disease and bovine spongiform encephalopathy.7U.S. Customs and Border Protection. Bringing Agricultural Products Into the United States
Here’s the part most travelers miss: if you declare an agricultural item and the inspector says it can’t enter, there’s no fine and no penalty. The item is confiscated and that’s the end of it.8Animal and Plant Health Inspection Service (APHIS). Traveling With Food or Agricultural Products But if you fail to declare a prohibited item and an inspector finds it, you face confiscation and potential fines. When in doubt, check “yes” on the agricultural question.
Duty-Free Allowance and What Gets Taxed
Returning U.S. residents can bring back goods worth up to $800 without paying duty, provided you’ve been outside the country for at least 48 hours and haven’t claimed the exemption in the previous 30 days.9eCFR. 19 CFR Part 148 – Personal Declarations and Exemptions The goods must accompany you and be for personal use.
Travelers arriving directly or indirectly from American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, or the U.S. Virgin Islands get a higher exemption of $1,600, though no more than $800 of that can cover goods acquired outside those locations.
For the first $1,000 worth of goods beyond your personal exemption, you pay a flat duty rate of 3 percent rather than item-by-item rates. Arriving from the U.S. insular possessions drops the flat rate to 1.5 percent on goods acquired there. Anything beyond that $1,000 flat-rate window is assessed at the full tariff rate for each item under the Harmonized Tariff Schedule.10U.S. International Trade Commission. Harmonized Tariff Schedule
Gifts Mailed to the U.S.
A different rule applies to gifts you mail rather than carry. Mailed gifts worth up to $100 per recipient per day enter duty-free, but if any single item in the package exceeds $100, the entire package becomes dutiable.11U.S. Customs and Border Protection. Gifts Mailed gifts containing alcohol, tobacco, or perfume with alcohol valued over $5 don’t qualify.
Alcohol and Tobacco
You can bring back one liter of alcohol duty-free as part of your personal exemption if you’re at least 21 and the alcohol is for personal use. Federal law doesn’t set a hard cap on personal-use quantities beyond that, but anything over one liter is dutiable, and state alcohol control laws may impose stricter limits. CBP enforces whichever rule is more restrictive at your port of entry.12U.S. Customs and Border Protection. Customs Duty Information
The duty-free tobacco allowance is 200 cigarettes, 50 cigars, or 2 kilograms of smoking tobacco.13eCFR. 19 CFR 148.43 – Tobacco Products and Alcoholic Beverages Cuban cigars and other Cuban tobacco products cannot be brought in as accompanied baggage. As of September 2020, even authorized travelers to Cuba are prohibited from returning with Cuban alcohol or tobacco for personal use.14U.S. Customs and Border Protection. Bringing in Cuban Goods and/or Cigars Into the United States
Medications
The FDA generally allows a personal supply of up to 90 days for medications you bring or ship into the country. Medications not approved by the FDA may be confiscated even if a foreign doctor prescribed them.15U.S. Food and Drug Administration. Personal Importation
If your medication is also a controlled substance, additional rules apply. Medications containing potentially addictive ingredients like certain cough medicines, tranquilizers, sleeping pills, or stimulants must be declared, kept in original packaging, and accompanied by a prescription or doctor’s statement. U.S. residents entering through a land border without a prescription from a U.S.-licensed, DEA-registered practitioner are limited to 50 dosage units of a controlled substance.16U.S. Customs and Border Protection. Traveling With Medications
Rohypnol, GHB, and Fen-Phen cannot be brought into the United States under any circumstances, regardless of prescription status.
Firearms, Pets, and Counterfeits
Importing firearms and ammunition requires appropriate federal permits and licenses. The Gun Control Act prohibits importation of firearms with no sporting purpose, and most travelers won’t be able to bring a firearm in without going through the licensing process in advance. Contact CBP and the Bureau of Alcohol, Tobacco, Firearms, and Explosives well before your trip.
Bringing a dog into the United States requires completing a CDC Dog Import Form, updated in February 2026. For dogs that have been only in rabies-free or low-risk countries during the six months before entry, the form receipt is the only document you need. It’s valid for multiple entries from the same country within six months of issuance and must be shown to the airline before boarding and to CBP on arrival.17Centers for Disease Control and Prevention. CDC Dog Import Form and Instructions Dogs arriving from high-risk rabies countries face additional vaccination and documentation requirements.
CBP seizes goods bearing counterfeit trademarks, but there’s a narrow personal-use exception. You can bring in one counterfeit article of each type every 30 days for personal use without penalty.18eCFR. 19 CFR 148.55 – Exemption for Articles Bearing Counterfeit Marks Anything beyond one item per type, or items clearly intended for resale, will be detained and destroyed.
Inspections and Device Searches
On arrival, a CBP officer checks your passport, visa if applicable, and declaration form during primary inspection. Most travelers clear this in minutes. Prior violations, travel patterns, incomplete declarations, or risk assessments run through CBP’s Automated Targeting System may trigger secondary screening, where officers conduct a more detailed review of your belongings and travel documents. Federal law authorizes CBP to search persons and baggage entering from foreign countries without a warrant.19Office of the Law Revision Counsel. 19 U.S.C. 1582 – Search of Persons and Baggage There is no set time limit on these searches.
CBP treats phones, laptops, and other electronic devices under a two-tier framework. A basic search, where an officer manually reviews what’s on the device, can be done without any suspicion. An advanced search, where an officer connects external equipment to copy or forensically analyze the device’s contents, requires reasonable suspicion of a legal violation and approval from a supervisor at the GS-14 level or higher.20U.S. Customs and Border Protection (CBP). CBP Directive No. 3340-049A Border Search of Electronic Devices Officers can ask for your passcode. If you refuse or the device is encrypted in a way they can’t access, CBP may detain the device.
U.S. citizens, lawful permanent residents, Canadian visitors with B1/B2 visas, and returning Visa Waiver Program travelers with an approved ESTA can use the Mobile Passport Control app to submit their customs declaration and passport information electronically before arriving.21U.S. Customs and Border Protection. Mobile Passport Control It doesn’t replace the need for proper documents, but it can shorten your wait.
Penalties If You Don’t Declare
Any article you fail to declare before your baggage is examined is subject to forfeiture. On top of losing the item, you face a penalty equal to its value. If the undeclared item is a controlled substance, the penalty jumps to $500 or 1,000 percent of the item’s value, whichever is greater.22Office of the Law Revision Counsel. 19 U.S.C. 1497 – Penalties for Failure to Declare
Deliberately smuggling goods or falsifying import documents is a federal crime under 18 U.S.C. 545, carrying a maximum prison sentence of 20 years. Even without criminal charges, CBP can pursue civil penalties and forfeit everything involved in the violation.
How to Fight a Seizure or Penalty
If CBP seizes your property or assesses a penalty, you can file a petition challenging the action. The petition deadline for seizures is generally 30 days from the date the notice of seizure is mailed. For penalty assessments, you typically get 60 days from the date of the penalty notice.23U.S. Customs and Border Protection. Customs Administrative Enforcement Process – Fines, Penalties, Forfeitures and Liquidated Damages Missing these deadlines can result in administrative forfeiture, meaning CBP takes full title to the property with no further process.24Federal Register. Administrative Forfeiture – New Publication Timeline for the Notice of Seizure and Intent to Forfeit
CBP has discretion to reduce penalties or return seized property through mitigation. The decision weighs factors like whether the violation was intentional, your compliance history, and the nature of what was seized. A first-time traveler who genuinely forgot to declare tends to get a better outcome than a repeat offender. You can also make an offer in compromise at any time before forfeiture becomes final.
If CBP denies your petition, you can file a claim to move the matter into federal court for a judicial forfeiture proceeding. At that point, hiring an attorney experienced in customs law is worth the cost. The procedural rules are specific and the government has the burden-of-proof advantage in forfeiture cases.
Effect on Global Entry
A customs violation doesn’t just affect the trip where it happens. If you hold Global Entry or another Trusted Traveler Program membership, CBP can revoke your status based on a violation. You’ll receive a written explanation of the reason for denial or revocation.25U.S. Customs and Border Protection. Trusted Traveler Program Denials
If you believe the decision was based on inaccurate or incomplete information, you can request reconsideration through the Trusted Traveler Programs website. The request goes to the CBP Ombudsman and should include the date and reason for the denial, a summary of the circumstances, and court disposition documents for any arrests or convictions, even expunged ones. There’s no published filing deadline, but submitting promptly with complete documentation gives you the best chance at a reversal.
