U.S. customs regulations: Prohibited and restricted items

Food products
Food is one of the most common sources of confusion for international travelers entering the United States. Many food products are allowed, but certain categories must be declared and may be subject to inspection.

Agricultural products include more than just fresh food. Some processed products made from animal or plant ingredients are also regulated. Import requirements can vary depending on the country of origin and may change in response to animal disease outbreaks or plant health concerns.

Before traveling, pay particular attention to:

• Meat and meat products
• Poultry
• Fresh fruits and vegetables
• Dairy products
• Eggs
• Plants and seeds
• Foods containing ingredients of animal or plant origin

Don't assume that a product is allowed simply because you bought it at a grocery store. Even commercially packaged food is not automatically permitted into the United States.

Meat and meat products
Meat is subject to particularly strict import regulations. Whether a specific product is allowed depends on several factors, including where it originated or was processed and the animal health conditions in that country.

The U.S. Department of Agriculture (USDA) notes that meat import restrictions can change in response to animal disease outbreaks. Certain meat products from specific countries may be prohibited, while others may be allowed if travelers can provide proof of origin and meet additional requirements.

For this reason, don't automatically pack sausage, smoked meat, dried meat, or other meat products in your luggage without checking the rules first.

Fruits and vegetables
Fresh fruits and vegetables must be declared when entering the United States. Many are prohibited or may be brought into the country only under specific conditions. These restrictions help prevent insects, larvae, plant diseases, and other agricultural pests from entering the United States.

The country of origin is particularly important. The same fruit may be subject to different import requirements depending on where it was grown. USDA maintains official databases that allow travelers to check import requirements based on the product and its country of origin.

Plants, seeds, and soil
Plants and seeds are also subject to strict import controls. Certain varieties may be imported only if specific requirements are met, while others are prohibited altogether. Soil deserves special attention. Bringing soil from foreign countries into the United States is prohibited without the required authorization because it may contain harmful pests and plant pathogens.

Avoid packing items such as:

• Soil from gardens or farms
• Plants with soil attached to their roots
• Seeds of unknown origin
• Certain types of planting materials

Even small amounts of soil or plant material can create problems during an agricultural inspection.

Dairy products and eggs
Milk, cheese, eggs, and other animal-derived foods may also be subject to import restrictions. Whether a particular item is allowed depends on its ingredients, country of origin, and current animal health regulations. Even familiar foods intended only for personal consumption should be checked before traveling.

Some lower-risk products, such as certain baked goods, candy, chocolate, and specific types of cheese, are generally allowed.
However, exceptions exist, and the final decision on whether an item may enter the United States is made during inspection.

Pets and animal products
If you're traveling with a pet, there are additional requirements to consider. You generally cannot simply place an animal in a carrier and board a flight to the United States without checking the applicable rules. Different animal species are subject to different entry requirements.

Restrictions may also apply to animal-derived products, including:

• Pet food
• Animal treats
• Hides and skins
• Bones
• Feathers
• Hunting trophies
• Other animal parts and products

Some live animals and animal products may be prohibited or require special permits and veterinary documentation. If you're planning to bring a pet, check the relevant requirements well before purchasing your airline tickets.

Medications
Traveling with medications requires additional care. Just because a medication is available over the counter in your home country doesn't necessarily mean you can bring it into the United States without restrictions.

This is particularly important for medications containing controlled substances or ingredients regulated under U.S. law. If you take medication regularly, it's a good idea to keep it in its original packaging and carry documentation supporting its medical use, especially for prescription medications.

Before traveling, check the current requirements of the appropriate U.S. authorities for the specific medications you plan to bring.

Alcohol and tobacco products
Alcohol and tobacco products are regulated and should not be treated as unrestricted personal belongings. In addition to federal requirements, individual states may impose their own restrictions. Taxes, quantity limits, and other regulations may apply when bringing alcohol or tobacco products into the country.

If you're traveling with significant quantities, check both federal import requirements and the rules of the state where you plan to arrive.

Firearms and ammunition
Importing firearms and ammunition into the United States is much more heavily regulated than bringing ordinary personal belongings. Depending on the type of firearm, country of origin, traveler's legal status, and purpose of importation, special permits and supporting documentation may be required.

U.S. Customs and Border Protection (CBP) notes that importing firearms and ammunition may involve additional forms and procedures administered by the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF). For this reason, firearms, ammunition, and related items should never be packed without first confirming all applicable import and airline requirements.

Cultural artifacts and antiques
Paintings, archaeological objects, antiques, and other cultural artifacts may also be subject to import restrictions. The issue isn't always whether an item can physically enter the United States. Travelers may also need to prove that it was legally acquired and exported from its country of origin.

In certain circumstances, supporting documentation may be required to establish ownership, purchase history, or lawful export. If you're planning to travel with antiques, artwork, or archaeological objects, check the applicable regulations before departure.

Wildlife and products made from protected species
Additional restrictions apply to certain animals, plants, and products made from protected wildlife species.
These may include:

• Hunting trophies
• Animal hides
• Bones
• Products made from rare or endangered animals
• Certain plant species
• Other wildlife products

Some items require special permits, while others are prohibited from importation. Travelers should verify the rules before purchasing or transporting products made from wildlife.

Why you should declare restricted or prohibited food
One of the most important rules when entering the United States is to never hide food or agricultural products from customs officials. If you're unsure whether an item is allowed, it's safer to declare it.

CBP and USDA explain that declared agricultural products may be inspected. If an inspector determines that an item cannot be brought into the country, the traveler may be required to surrender it. In general, travelers who properly declare prohibited agricultural products are not penalized simply for bringing the items to the attention of an inspector.

However, failing to declare restricted or prohibited items can lead to confiscation and civil penalties. Declaring an item doesn't guarantee that it will be allowed into the country, but it helps travelers comply with customs requirements.

What happens to prohibited items?
If a customs or agricultural inspector determines that an item cannot be admitted into the United States, it may be confiscated, or the traveler may be allowed to voluntarily surrender it. Agricultural products that are surrendered or seized are disposed of according to established procedures designed to prevent the spread of pests and diseases.

For this reason, it's not worth risking a penalty or unnecessary complications over a small package of food, a plant, or another restricted item.

What to do before traveling
Import requirements depend not only on the type of product but, in some cases, also on its country of origin. Regulations may also change in response to new outbreaks of animal or plant diseases.

Before traveling to the United States:

• Check the specific product using official CBP and USDA resources.
• Keep products in their original packaging with labels intact.
• Bring receipts or other documentation showing where an item originated.
• Declare agricultural products and products of animal origin.
• Avoid packing soil or questionable plant materials.
• Review the requirements for medications, pets, firearms, and other regulated items.

USDA recommends keeping receipts and original packaging for agricultural products because this information can help inspectors determine the country of origin. If you're unsure whether something is allowed, the safest approach is to research the requirements before traveling and declare the item when you arrive.

Key takeaways
When entering the United States, it's important to understand that not everything you can legally buy abroad is automatically permitted through U.S. customs. Pay particular attention to meat, dairy products, eggs, fresh fruits and vegetables, plants, seeds, soil, animals, and animal-derived products.

Many of these items are not universally prohibited, but they may require inspection or be subject to restrictions based on their origin.
Always declare agricultural products and other items that must be reported to customs authorities.

The final decision on whether a product may enter the United States rests with the appropriate customs or agricultural inspector.
Even if you've checked the rules before traveling, that doesn't guarantee an item will be admitted. Reviewing current CBP and USDA requirements, keeping supporting documentation, and declaring regulated products can help you avoid unnecessary delays, confiscation, and penalties.
