U.S. Customs and Border Protection sorts everything in your luggage into two very different buckets, and knowing which is which is the difference between a five-minute inspection and a $300 fine. Prohibited means the item is forbidden by law to enter the United States, and no paperwork will save it. Restricted means the item is allowed, but only with a license, permit, or certificate from a federal agency before it arrives.
CBP itself draws that line in its official traveler guidance. Prohibited examples the agency lists include bush meat, dangerous toys, and cars that fail U.S. crash standards. Restricted examples include firearms, certain fruits and vegetables, animal products, animal by-products, and some live animals. The same physical object can sit in either bucket depending on where you bought it and what documents you carry.
The scope is larger than most travelers expect. CBP enforces hundreds of laws on behalf of 40 other federal agencies, including the U.S. Fish and Wildlife Service, the U.S. Department of Agriculture, the Food and Drug Administration, and the Centers for Disease Control and Prevention. The officer at the podium is applying rules written by agencies you may never have heard of.
Free toolB1/B2 Tourist Visa Stay Calculator onlineThe financial stakes are concrete. CBP states that the civil penalty for failing to declare agricultural items costs first-time offenders $300, rising to $500 for a second violation. On its separate agricultural-products guidance, CBP puts the ceiling higher, stating that civil penalties for failure to declare prohibited agricultural products may range up to $1,000 per first-time offense for non-commercial quantities, with much higher assessments when the goods are judged commercial.
Here is the part that saves travelers money: none of those penalties apply if you declare. CBP is explicit that declared agriculture items in non-commercial quantities that turn out to be prohibited can simply be abandoned at the port of entry, and the traveler continues into the country. Only undeclared items get confiscated and generate a penalty.
This guide organizes the CBP prohibited and restricted list by category, so you can check your bag against it before you fly. It covers food and agriculture, plants and soil, wildlife products, medications, currency, counterfeits, alcohol and tobacco, weapons, and biological materials, then closes with the penalty schedule and how the amnesty bins actually work.
For the mechanics of the declaration itself, including what to write on the form and how the questions are worded, see our companion reference on items you must declare at US customs. This guide answers the prior question: what is banned outright, and what is merely conditional.
Prohibited vs. Restricted: The Distinction That Decides Everything
Travelers routinely use the two words interchangeably. CBP does not. The classification determines whether a permit exists that could make your item legal, and whether the item is destroyed or released after inspection.
A prohibited item cannot be imported under any circumstance available to an ordinary traveler. A restricted item is admissible the moment you produce the right federal document, which almost always has to be obtained in advance, in the country of origin, before you travel.
| Prohibited | Restricted | |
|---|---|---|
| CBP definition | Forbidden by law to enter the U.S. | Requires a license or permit from a federal agency |
| Can paperwork fix it | No | Yes, if obtained in advance |
| CBP examples | Bush meat, dangerous toys, non-compliant vehicles | Firearms, certain fruits and vegetables, animal products, some animals |
| Outcome at inspection | Seized and destroyed | Released on presentation of the permit |
| If you declared it | May be abandoned without penalty | Held until documents are produced |
When you are unsure which bucket an item falls into, declare it. Declaring an admissible item costs you nothing. Failing to declare a prohibited one starts the penalty clock.
Food, Meat, and Dairy
Meat is the strictest category on the list. CBP states you may not import fresh, dried, or canned meats or meat products from most foreign countries, and you may not import food products that have been prepared with meat. The rule reaches ingredients, not just cuts: if meat from a restricted country appears inside a product such as beef broth, the whole product is usually prohibited.
That catches items travelers think of as souvenirs rather than meat. Bouillon cubes, soup mixes, and packaged sauces containing meat extract are all covered. Bush meat made from African wildlife is flatly inadmissible.
The reason the rules change without warning is that they track disease outbreaks abroad, specifically foot-and-mouth disease and bovine spongiform encephalopathy. APHIS revises country eligibility as animal-health status changes, so a product that cleared customs last year may be barred this year.
- Bakery items and certain cheeses
- Condiments, vinegars, and cooking oils
- Packaged spices, honey, coffee, and tea
- Most prepared, shelf-stable foods without meat content
CBP advises avoiding rice entirely. Rice frequently harbors insects, and a bag of it is a common reason an otherwise clean suitcase gets pulled for secondary agricultural inspection.
Fresh Produce, Plants, Seeds, and Soil
Whether fresh fruit and vegetables are admissible depends on where you bought them and where you are headed after arrival. CBP’s guidance is blunt: it is best not to bring fresh fruits or vegetables into the United States at all. The airport apple you bought before boarding and never ate is exactly the item that triggers a secondary inspection.
The agency justifies that caution with a specific number. The Mediterranean fruit fly outbreak of the 1980s cost California and the federal government roughly $100 million to eradicate, and CBP attributes the cause to a single traveler carrying a single contaminated piece of fruit.
Seeds and anything propagative face a higher bar. Certain plants and any plant parts intended for growing require a foreign phytosanitary certificate obtained in advance. Every plant and plant product must be declared and presented for inspection, and that includes handicraft items made with straw, regardless of how pest-free they look.
Soil is close to an absolute bar. No soil or earth of any kind may enter the United States without a permit issued in advance by the USDA Plant Protection and Quarantine Permit Unit, and the permit must be verified at the port. Pure sand, such as a small container of decorative beach sand, is usually allowed, but check in advance.
- Seed potatoes from Canada require a permit
- Fresh tomatoes and bell peppers from Canada are prohibited
- Stone fruit, apples, mangoes, oranges, guavas, sopote, cherimoya, and sweet limes from Mexico require a permit
- Mexican avocados are enterable if peeled, halved, seed removed, and either in liquid or vacuum-packed
Check “Yes” on the declaration if you visited a farm or were near livestock. Agriculture specialists may need to inspect or disinfect your shoes for soil traces that can carry foot-and-mouth disease.
Wildlife, Ivory, and Animal Products
Endangered wildlife species and products made from them generally may not be imported or exported. The restriction reaches far past whole animals: it covers any part or product, including skins, tusks, bone, feathers, and eggs, and articles manufactured from wildlife or fish.
Ivory deserves its own warning because the souvenir trade is large and the rule is near-total. You need a permit from the U.S. Fish and Wildlife Service to import virtually all types of ivory, with one narrow exception: warthog ivory. FWS maintains separate restrictions for Asian elephant, African elephant, whale, rhinoceros, and seal ivory, along with pre-Endangered Species Act and post-CITES categories.
There is an antique route, and it is documentary rather than discretionary. Ivory may be imported if it is antique, which FWS defines as at least 100 years old, and you must carry documentation authenticating that age. The same condition applies to other antiques containing wildlife parts.
Anyone importing or exporting fish or wildlife must file FWS Form 3-177, the Declaration for Importation or Exportation of Fish or Wildlife, regardless of species. Only 14 ports of entry are currently designated to handle game and hunting trophies; other ports need FWS approval before they can clear your entry.
One wildlife category carries a dedicated penalty schedule. Under the Dog and Cat Protection Act of 2000, it is illegal to import, export, distribute, transport, manufacture, or sell products containing dog or cat fur, and each offending item is subject to seizure and forfeiture. The Act sets civil penalties of up to $10,000 for each knowing and intentional violation, $5,000 for each gross negligent violation, and $3,000 for each negligent violation.
State law can be stricter than federal law, and CBP applies the stricter standard. A trophy or wildlife article legal federally can still be refused if your destination state bars it.
Medications and Drug Paraphernalia
The FDA regulates every human and animal drug entering the country, and the DEA adds a second layer whenever the medication is a controlled substance. The rules split sharply depending on your citizenship.
For non-U.S. citizens visiting temporarily, CBP’s guidance is workable. Carry a valid prescription or a doctor’s note written in English. Keep medication in its original container with the doctor’s instructions printed on the bottle. Travel with no more than you need, and CBP offers a rule of thumb of no more than a 90-day supply. If you are staying longer than 90 days, additional medication can be mailed or couriered to you with documentation showing it is for your own use, which may include a copy of your visa and passport, a letter from your doctor, and a copy of the prescription in English.
For U.S. citizens the rule is more restrictive than most travelers assume. CBP states that in most cases it is illegal for a U.S. citizen to obtain drugs outside the United States and import them for personal use, because foreign-made versions have not been evaluated or approved by the FDA and are generally considered unapproved drugs.
Separately, the FDA prohibits importing fraudulent or counterfeit drugs and medical devices by mail or in person, a category that includes unorthodox “cures” marketed for cancer, AIDS, arthritis, or multiple sclerosis.
Drug paraphernalia is prohibited unless prescribed for an authentic medical condition such as diabetes. CBP seizes any illegal paraphernalia, and conviction for importing it carries fines and imprisonment.
Currency and Monetary Instruments Over $10,000
Carrying cash into or out of the United States is not illegal at any amount. Failing to report it is. Federal law requires anyone who brings, sends, or receives currency or monetary instruments totaling more than $10,000 at one time, in either direction, to report it to CBP on FinCEN Form 105.
The trap is aggregation. When families or groups travel together, the $10,000 threshold applies to the total the group is carrying collectively, not to each individual. Four travelers with $3,000 each have crossed the threshold and must file.
“Monetary instruments” is broader than banknotes. It covers U.S. and foreign coins and currency, traveler’s checks in any form, negotiable instruments such as checks, promissory notes, and money orders that are in bearer form or endorsed without restriction or made out to a fictitious payee, signed instruments with the payee’s name left blank, and securities or stock in bearer form. Checks made payable to a named person that carry no endorsement or a restrictive endorsement are generally not counted, and neither are warehouse receipts or bills of lading.
The consequences of skipping the filing are severe. CBP states that an individual who fails to file, or who submits false or fraudulent information, risks having the currency or monetary instruments forfeited and seized, and may face civil or criminal penalties including fines or imprisonment under 31 U.S.C. 5317, 5321, 5322, and 5332. Travelers using Mobile Passport Control can submit the report electronically alongside their entry declaration. Gold is handled under separate rules; see our breakdown of customs duty-free gold carrying limits.
Counterfeit and Pirated Goods
Articles that infringe a federally registered trademark or a copyright protected under the Berne Convention are subject to detention and seizure. Goods bearing counterfeit marks are subject to seizure and forfeiture outright, and importing counterfeit-marked articles intended for sale or public distribution can expose you to a civil fine when the genuine trademark is recorded with CBP.
There is a narrow personal exemption, and it is more limited than the street-market assumption. An arriving traveler may import one article of each type bearing a counterfeit, confusingly similar, or restricted gray market trademark, provided the article accompanies the person, is for personal use, and is not for sale. The exemption may be granted no more than once every 30 days.
CBP’s own example is instructive: a traveler arriving with three handbags is permitted to keep exactly one, whether all three carry the same infringing mark or three different ones. The other two are forfeited. If an article admitted under the personal exemption is sold within one year of importation, the article or its value is subject to forfeiture.
A parallel personal-use exemption applies to pirated copyrighted articles. Genuine trademarked and copyrighted goods may be brought back normally, subject to duty. The categories CBP sees most often are handbags and accessories, clothing, software on discs, sound recordings, toys, DVDs, and books.
Alcohol and Tobacco Allowances
Alcohol and tobacco are restricted by quantity rather than banned, and the allowances sit inside the standard $800 duty-free personal exemption available to a returning resident once every 31 days after at least 48 hours abroad.
One American liter, or 33.8 fluid ounces, of alcoholic beverages may be included in that exemption if you are at least 21, the alcohol is exclusively for personal use and not for sale, and it does not violate the law of the state where you arrive. Tobacco is capped at 200 cigarettes and 100 cigars, and that allowance also requires you to be 21 or over.
| General merchandise exemption | $800 |
| Frequency of exemption | Every 31 days |
| Minimum time abroad | 48 hours |
| Alcohol, duty-free (age 21+) | 1 liter |
| Cigarettes (age 21+) | 200 |
| Cigars (age 21+) | 100 |
| Duty on the second liter of liquor | 3% plus IRT |
Alcohol above the allowance is taxed even if you never reach your $800 limit. CBP’s worked example: return from Europe with $200 of purchases including two liters of liquor, and the first liter is duty-free while the second is dutiable at 3 percent plus any Internal Revenue Tax. Bring back three liters of wine and nothing else, and two of the three are dutiable and taxed.
Federal rules set no hard ceiling above the exemption, but volume attracts scrutiny. CBP officers enforce ATF rules and are authorized to make on-the-spot determinations that an importation is commercial, which forces you to obtain a permit and file a formal entry before the alcohol is released. Tobacco quantities beyond the exemption are subject to detention, seizure, penalties, abandonment, and destruction. For how the $800 threshold plays out in practice, see our report on CBP’s warning to shoppers on the duty-free exemption.
The law of the state where you first arrive governs how much alcohol you may bring and whether you need a license. Contact that state’s alcoholic beverage control board before you depart.
Weapons, Ammunition, and Biological Materials
Firearms are restricted rather than prohibited, and the paperwork burden falls on the outbound leg as much as the return. Temporarily taking a firearm or ammunition abroad is governed by the Export Administration Regulations administered by the Bureau of Industry and Security, and a BIS license is generally required. Many travelers instead rely on the Baggage license exception at 15 CFR 740.14.
Using that exception requires presenting the firearms and ammunition to a CBP officer before departure and completing CBP Form 4457, the Certificate of Registration for Personal Effects Taken Abroad. You then present Form 4457 along with the firearm and any unused ammunition when you return.
Form 4457 is only a re-entry document for the United States. It does not authorize entry into the country you are visiting, and complying with that country’s import law remains your responsibility.
Biological materials are restricted through a strict permitting process. A USDA permit, a CDC permit, or both may be required for bacterial cultures, culture medium, excretions, fungi, arthropods, mollusks, tissues of livestock, birds and plants, viruses, and vectors imported for research, biological, or pharmaceutical use. All such materials must be declared and presented for inspection on arrival.
Two smaller categories catch travelers off guard. Absinthe is admissible only if it is thujone free, meaning under 10 parts per million, with “absinthe” barred from being the brand name or standing alone on the label and no hallucinogenic imagery on the artwork; non-compliant bottles are seized. Animal hide drums from Haiti are restricted by the CDC unless processed to be non-infectious, after goat hide drums were linked to a case of cutaneous anthrax.
Penalties and How Amnesty Bins Work
The penalty for a prohibited item is not the item’s value. It is a civil fine assessed for the failure to declare, and it applies whether or not you knew the item was banned.
| Agricultural items, first offense | $300 |
| Agricultural items, second violation | $500 |
| Prohibited ag products, non-commercial, first offense | Up to $1,000 |
| Dog or cat fur, negligent violation | $3,000 |
| Dog or cat fur, gross negligent violation | $5,000 |
| Dog or cat fur, knowing and intentional | $10,000 |
CBP publishes two figures for undeclared agriculture. Its prohibited-and-restricted-items guidance states $300 for a first-time offender and $500 for a second violation. Its agricultural-products guidance states that penalties may range up to $1,000 per first-time offense for non-commercial quantities, and that commercial-quantity violations are assessed at a much higher rate. The same fines apply to prohibited agricultural products sent through international mail.
The amnesty mechanism is the single most valuable thing to understand in this guide, and it is not a loophole. It is written into CBP policy: declared agriculture items in non-commercial quantities that agriculture specialists find to be prohibited or restricted can be abandoned at the port of entry, and the traveler continues into the United States without a fine.
In practice this is what the bins near the baggage hall are for. Many international arrival halls place amnesty or abandonment containers before the CBP inspection point so travelers can drop food, produce, and plant material before reaching an officer. Using one, or telling the officer you wish to abandon a declared item, converts a potential $300 penalty into a discarded apple.
The line is declaration, not disposal. Undeclared prohibited agriculture items are confiscated and can generate a civil penalty for failure to declare. Everything abandoned or confiscated is then destroyed using USDA-approved destruction methods to stop pests and diseases from spreading.
Declare agricultural items by checking “Yes” on Question 11 of CBP Form 6059B, and check “Yes” again if you visited a farm or were near livestock.
Common Mistakes That Trigger Penalties
Packaging has no bearing on admissibility. Canned and dried meats are prohibited from most countries just as fresh meat is, and a factory-sealed soup mix containing meat extract is treated as a meat product.
The threshold applies to the group’s combined total, not per traveler. Dividing $12,000 among three relatives does not avoid the filing requirement, and undeclared currency can be seized outright.
The personal exemption covers one article of each type, once every 30 days. Three handbags means one is kept and two are forfeited, and reselling the permitted article within a year forfeits it too.
The antique route requires the ivory to be at least 100 years old and requires documentation that authenticates that age. A seller’s verbal assurance is not documentation, and FWS permits cover virtually all other ivory.
Medication should stay in its original container with the doctor’s instructions on the bottle. Without the container, carry a copy of the prescription or a doctor’s letter in English explaining the condition.
Soil is prohibited without an advance USDA permit, and soil clinging to boots counts. Declaring farm contact lets specialists clean the footwear instead of assessing a failure-to-declare penalty.
Before You Fly: What to Do Next
Work backwards from the two buckets. Anything on the prohibited list should come out of your bag before you leave the foreign country, because no document will rescue it at the border. Anything restricted needs its permit, certificate, or declaration form secured in advance, usually from the country of origin, since permits are almost never issued at the port of entry.
Then declare everything that touches agriculture, wildlife, currency above the threshold, or commercial quantities. The declaration is what converts a fine into an inspection. Our guide to filling out CBP Form 6059B walks through each question, and our overview of the customs process on international flights explains what happens between the jet bridge and the exit.
According to analysis by VisaVerge.com, the travelers who get fined are rarely smugglers. They are people who packed a piece of fruit, a jar of honey with meat content, or a souvenir made from an animal, and then answered “No” on the form because the item seemed too small to matter. CBP’s own rule turns that judgment call into a $300 decision.
Rules change with disease outbreaks and sanctions updates, so confirm current status before departure on CBP’s Prohibited and Restricted Items page and USDA APHIS guidance for agricultural products.
Frequently Asked Questions
What is the difference between prohibited and restricted items at US customs?
CBP defines prohibited as forbidden by law to enter the United States, with no permit available. Restricted means the item is allowed once you hold a license or permit from a federal agency. CBP lists bush meat and dangerous toys as prohibited, and firearms, certain fruits and vegetables, and animal products as restricted.
How much is the fine for not declaring food at US customs?
CBP states the civil penalty for failing to declare agricultural items costs first-time offenders $300, rising to $500 for a second violation. CBP’s agricultural-products guidance puts the range up to $1,000 per first-time offense for non-commercial quantities, with much higher assessments for commercial quantities. The same fines apply to prohibited agricultural products sent by international mail.
Can I throw away food at the airport instead of paying a customs fine?
Yes, if you declare it first. CBP policy allows declared agriculture items in non-commercial quantities that are found prohibited or restricted to be abandoned at the port of entry so the traveler can continue into the country. Undeclared prohibited items are confiscated instead and can generate a failure-to-declare penalty.
How much cash can I bring into the US without declaring it?
You may carry any amount, but anything over $10,000 must be reported to CBP on FinCEN Form 105. For families or groups traveling together, the $10,000 threshold applies to the combined total, not per person. Failure to file risks seizure and forfeiture plus civil or criminal penalties.
Can I bring meat or dairy products into the United States?
CBP prohibits importing fresh, dried, or canned meats and meat products from most foreign countries, and foods prepared with meat. Products containing meat as an ingredient, such as beef broth or soup mixes, are usually prohibited too. Bakery items and certain cheeses are admissible, as are honey, coffee, tea, and packaged spices.
Is it legal to bring ivory souvenirs back to the US?
You need a US Fish and Wildlife Service permit to import virtually all types of ivory, with warthog ivory the only exception CBP names. Antique ivory may be imported if it is at least 100 years old and you carry documentation authenticating that age. Anyone importing wildlife must also file FWS Form 3-177.
How many counterfeit items can I bring through US customs?
One article of each type, and no more than once every 30 days. The article must accompany you, be for personal use, and not be for sale. CBP’s example is a traveler with three handbags keeping only one. Selling the permitted article within a year subjects it or its value to forfeiture.
How much alcohol and tobacco can I bring into the US duty-free?
One American liter of alcohol, or 33.8 fluid ounces, plus 200 cigarettes and 100 cigars, all requiring you to be at least 21. These sit inside the $800 personal exemption available every 31 days after 48 hours abroad. A second liter of liquor is dutiable at 3 percent plus Internal Revenue Tax.
