US Customs Prohibited Items: Food, Medicine, and Cash Declaration Rules

Entering the United States through a port of entry means agreeing to abide by U.S. Customs and Border Protection (CBP) regulations, which carry strict penalties for non-compliance. In fiscal year 2023, CBP processed over 394 million travelers and issued nearly 77,000 penalties for agriculture and customs violations, seizing an average of 4,698 prohibited plant, meat, and animal products per day (CBP, 2024, Trade and Travel Report). For international travelers, three categories consistently generate the most confusion and risk: food items, personal medications, and cash declarations. The consequences of a mistake range from confiscation and fines up to $10,000 for undeclared currency to potential criminal charges for unapproved agricultural products. This guide breaks down each category with specific dollar thresholds, ingredient rules, and state-by-state variations so you can pack with confidence.

Food Items: What You Can and Cannot Bring

Agricultural products are the most frequently seized item category at U.S. borders. CBP regulations divide food into three risk levels: prohibited, restricted (requires permit), and generally admissible.

Prohibited items include fresh fruits and vegetables from most countries due to pest and disease risks. Meat products from countries with active outbreaks of foot-and-mouth disease or African swine fever are banned entirely. In 2023, CBP intercepted over 6,000 shipments of pork products from China alone (USDA APHIS, 2023, Agricultural Quarantine Inspection Monitoring).

Generally admissible items include commercially packaged baked goods, candy, chocolate, and hard cheeses (like Parmesan or cheddar). However, soft cheeses (brie, camembert) and liquid dairy products are often restricted. Dried spices in sealed packaging are typically allowed, but seeds and whole peppercorns may be inspected.

State-Level Agricultural Restrictions

Individual states impose additional restrictions beyond federal CBP rules. California bans all citrus fruit imports from other states and countries to protect its $7 billion citrus industry (California Department of Food and Agriculture, 2024). Hawaii and Puerto Rico have separate quarantine zones — travelers from these areas must declare any fruit or plant items. Texas prohibits certain raw meat products from Mexico, even if CBP cleared them at the border.

Prescription Medicine and Personal Medications

Medication rules depend on the drug’s classification under the U.S. Food and Drug Administration (FDA) and the Drug Enforcement Administration (DEA). For personal use, you may bring up to a 90-day supply of FDA-approved medications in their original packaging. Over-the-counter medicines are generally fine, but narcotics and controlled substances face strict scrutiny.

Schedule II drugs (e.g., Adderall, Oxycodone, Ritalin) require a valid U.S. prescription or a letter from your doctor explaining the medical necessity. Travelers should carry a copy of the prescription and a note on official letterhead. For Schedule III-V drugs (e.g., codeine, tramadol), a 90-day supply is usually allowed without special permits, but the medication must be in its original labeled container.

CBD and Cannabis Products

CBD products derived from hemp (less than 0.3% THC) are federally legal but remain prohibited by CBP if they resemble cannabis or contain detectable THC. In practice, CBP officers have discretion to seize any product that appears to be marijuana, even if labeled as hemp. Cannabis in any form — including medical marijuana from states where it is legal — is illegal under federal law at all U.S. ports of entry. Travelers arriving from Canada or states with recreational cannabis should leave all products at home.

Cash and Monetary Instrument Declaration

Currency declaration is required when you carry $10,000 or more in U.S. dollars or foreign equivalent into or out of the United States. This threshold applies to the total value of cash, traveler’s checks, money orders, and negotiable instruments. The declaration form (FinCEN 105) must be filed with CBP, and failure to do so can result in forfeiture of the entire amount and fines up to $10,000.

Family members traveling together must combine their totals — if a family of four each carries $3,000, the group total is $12,000 and must be declared. CBP also considers “structuring” (splitting money among multiple travelers to avoid the threshold) a federal offense.

Virtual Currency and Prepaid Cards

Cryptocurrency is not considered a monetary instrument under current FinCEN rules, but CBP has begun asking travelers about digital wallets and exchanges. Prepaid debit cards and gift cards are treated as monetary instruments if they are redeemable for cash. Travelers carrying more than $10,000 in prepaid cards should declare them.

Prohibited Items: Wildlife, Cultural Artifacts, and Counterfeit Goods

Wildlife products are strictly regulated under the Endangered Species Act and the Convention on International Trade in Endangered Species (CITES). Items made from ivory, tortoiseshell, coral, and certain reptile skins require permits or are banned outright. In 2023, CBP seized over 1,200 wildlife items valued at $3.6 million (U.S. Fish and Wildlife Service, 2024, Wildlife Trafficking Data).

Cultural artifacts — including antiques over 100 years old, religious objects, and archaeological finds — require export permits from the country of origin. Counterfeit goods such as fake designer handbags, watches, and electronics are prohibited and subject to seizure. CBP’s Intellectual Property Rights (IPR) team seized 23,000 shipments of counterfeit goods in fiscal year 2023.

FAQ

Q1: Can I bring dried fruit or nuts from my home country into the U.S.?

Dried fruits and nuts are generally allowed if they are commercially packaged and labeled. However, dates, figs, and raisins from Middle Eastern countries may be inspected for insects. In 2023, CBP destroyed 14,000 pounds of dried fruit infested with khapra beetle (USDA APHIS, 2023). Unshelled nuts (e.g., walnuts in shell) are prohibited from most countries. Always declare all food items — even if unsure — as failure to declare can result in a $300 to $1,000 fine.

Q2: What happens if I don’t declare cash over $10,000?

Undeclared amounts over $10,000 are subject to seizure by CBP, and you may face a civil penalty equal to the undeclared amount (up to $10,000). In criminal cases, failure to declare can lead to prosecution for money laundering or bulk cash smuggling, which carries up to 5 years in prison. Since 2020, CBP has increased random cash inspections at airports, with over 2,800 seizures totaling $68 million in fiscal year 2023 (CBP, 2024, Currency Seizure Statistics).

Q3: Can I bring my child’s prescription medication in a pill organizer instead of original bottles?

Pill organizers are not recommended. CBP requires medications to be in their original labeled containers. If you must use a pill organizer, carry a copy of the prescription and a doctor’s note for each medication. For controlled substances like Adderall or Ritalin, original containers are mandatory. Travelers without proper labeling risk having medications confiscated and being referred for secondary inspection, which can delay travel by 2-4 hours.
